Assessment of Two Years of Free Surgical Treatment of Cleft Lip, Palate and Alveolar (CLPA) in the Maxillofacial Surgery and Stomatology Department of the Hospital University of Treichville-Abidjan

Introduction: Cleft lip, palate and alveolar (CLPA) are congenital malformations of the face due to a defect in the fusion of embryonic buds during the first weeks of embryogenesis. These malformations affect the upper lip, the alveolar bone and the palate. The incidence in Africa ranges from 1/2000 to 1/500 births. Their multidisciplinary management is long and costly. Thus, the help provided by humanitarian organisations during free care campaigns is welcome. Materials and Methods: This is a retrospective descriptive study conducted from August 2014 to July 2016 in the Maxillofacial Surgery and Stomatology Department of the Treichville University Hospital in Abidjan, Côte d’Ivoire. The objective was to describe the epidemiological, clinical and therapeutic aspects of CLPA during a humanitarian campaign for free care. Results: 51 cases of CLPA were operated on. Males were involved in 54.9% of the cases, i.e. a sex ratio of 1.2. The average age of the patients at the time of the operation was 3.44 years with extremes of 3 months and 52 years. Patients with low socioeconomic status represented 84.3% of the cases. Cleft lips (31.4%) and cleft palates (33.33%) predominated. For cleft lips, unilateral forms were the most frequent (73.5%) and the left side was most often affected (59.2%). The most common surgical techniques used were MILLARD cheiloplasty for cleft lips (79.36%) and Dorrance pushback for cleft palates (78.05%). The postoperative course was simple in the majority of cases (80.47%). Patients and/or parents were satisfied with the postoperative results in over 90% of cases. Discussion: Cleft lip and palate are common. Their management by humanitarian missions through mass campaigns allows us to receive a large number of patients affected by this pathology who are treated with a high satisfaction rate. Conclusion: The characteristics of cleft lip and palate in this study are in many respects identical to those described in the literature, but with some differences specific to Africa, notably the absence of antenatal diagnosis and the advanced age at the time of treatment.

Rhinoplasty in Cleft Lip and Palate

Various surgical techniques and approaches have been described to repair cleft nose deformities. It is necessary to consider that since it is a congenital deformity, surgical management must consider the patient’s growth process, as well as the healing itself from the surgery. The present study aims to evaluate an alternative solution to secondary rhinology, aesthetic, and functional alterations to unilateral or bilateral cleft lift palate to minimize deformities and ensure good results. 11 patients were studied between 1995 to 2002, ten male and one female. In 8 cases, the patients had a history of cleft lip and palate on the left side, 2 patients with cleft lift palate on the right, and 1 patient with bilateral cleft lip and palate. 100% of the patients increased their naso-labial angle. This improved their appearance and structure, starting from a preoperative arithmetic mean of 39 degrees to a postoperative arithmetic mean of 96 degrees. Such intervention increased the naso-labial angle by 57 degrees. At the base of the nose, it was possible to improve the inclination of the alar line (line B) in 10 of the cases with a variation of 2 to 3 mm in relation to the perpendicular line A and only one case remained with the same inclination.

When the Combination of a Chinese Flap and Dufourmentel Makes It Possible to Treat a Hopeless Case of Squamous Cell Carcinoma of the Upper Lip

Cancers of the lip are the leading cause of labial defects, and treatment is essentially surgical. The success of a repair is assessed by two essential criteria: The functional character of the lip (restoration of continence allowing feeding) and the aesthetic quality of the repair. However, for many patients from countries whose medical infrastructure does not allow them to undertake complex reconstructions locally, medical transfers represent their only chance of treatment. The aim of this article is to share with you an extreme clinical case of labial reconstruction, the management of which was a real challenge, using two major flaps: the free ante-brachial flap and the DUFOURMENTEL-type bi-pediculated scalp flap.

Epidemiology, Clinical Aspects and Management of Cleft Lip and/or Palate in Burkina Faso: A Humanitarian Pediatric Surgery-Based Study

Background: Cleft lip and/or palate are the most common orofacial malformations. Many studies, especially in developed countries have been conducted on this malformation, but in Burkina Faso, data are scarce and they are not specific to children. The aim of this study was to report the epidemiological, clinical and therapeutic aspects of cleft lip and/or palate in children in a low-income country. Materials and Method: The authors conducted a retrospective descriptive study based on data of three humanitarian missions of pediatric reconstructive facial surgery which took place in 2007, 2010 and 2014 at Clinique El Fateh-Suka in Ouagadougou, Burkina Faso. All children of 0 - 14 years of age, presenting with cleft lip and/or palate, were included in the study. Results: A total of 185 cases of cleft lip and/or palate were seen during these three humanitarian surgery missions. There were 100 boys and 85 girls. The average age of the children was 2.4 ± 3.2 years [0 - 12 years];there were 8.7% newborns. The commonest type of cleft was cleft lip and palate (49.7%) followed by isolated cleft lip (48.7%) and isolated cleft palate (1.6%). The left side was the most affected (49.2%). In 21.1% of cases, clefts were associated with other congenital malformations. In total, 150 of 185 (81.1%) children underwent surgery and there were no postoperative complications reported. Conclusions: Epidemiological and clinical characteristics of cleft lip and/or palate observed in this study are not very different from those described elsewhere in Africa. However, in our conditions, there are circumstances and structural factors which hinder the diagnosis and constitute challenges that must be addressed for adequate management of this congenital, highly disfiguring malformation.

Review on the clinical application of autologous fattransplantation in secondary lip malformation after cleft lip surgery

Congenital cleft lip is a common congenital defect.At present,surgical treatment is the only effective treatment for congenital cleft lip.Currently,there are many surgical methods for cleft lip.Many scholars continue to the improvement of surgical methods,and the immediate effect after surgery is significantly improved.However,despite the continuous improvement of surgical methods,lip and nose deformities are inevitably left after cleft lip.Because the lip occupies an important aesthetic position in the face,the restoration of secondary lip deformity after cleft lip surgery has important clinical significance.There are individual differences in secondary lip deformities in patients with cleft lip,and there are various methods of rehabilitation.There is no uniform treatment standard.This article mainly focuses on the current treatment progress of secondary lip deformities after cleft lip,especially autologous fat transplantation in secondary lip deformity after cleft lip is reviewed as follows.

Accurate diagnosis of prenatal cleft lip/palate by understanding the embryology

Cleft lip with or without cleft palate(CP) is one of the most common congenital malformations. Ultrasonographers involved in the routine 20-wk ultrasound screening could encounter these malformations. The face and palate develop in a very characteristic way. For ultrasonographers involved in screening these patients it is crucial to have a thorough understanding of the embryology of the face. This could help them to make a more accurate diagnosis and save time during the ultrasound. Subsequently, the current postnatal classification will be discussed to facilitate the communication with the CP teams.

BHMT Gene Polymorphisms as Risk Factors for Cleft Lip and Cleft Palate in a Chinese Population

Objective Convincing evidence suggests a link between increased risk of nonsyndromic cleft lip with or without cleft palate （NSCL/P） and low intake of folic acid by the mother during pregnancy. The present study was designed to explore if genetic variation in the betaine‐homocysteine methyltransferase （BHMT） gene contributes to NSCL/P. Methods DNA was obtained from 166 individuals with NSCL/P and 285 healthy subjects. Three known single nucleotide polymorphisms （SNPs） present in the BHMT gene （rs651852, rs3797546, and rs3733890） were investigated by real‐time PCR‐based TaqMan genotyping. Results Neither allelic nor genotypic association was found between NSCL/P and SNPs rs651852 and rs3733890. SNP rs3797546 did not show allelic association with NSCL/P; however, a higher proportion of NSCL/P patients carry the CC genotype compared with the TT＋CT genotype （P=0.020, OR=2.10, 95% CI=1.11‐3.95）. Conclusion Our study suggests that polymorphism rs3797546 in the BHMT gene may confer genetic risk of NSCL/P in a recessive manner.

Genome-wide and Interaction Linkage Scan for Nonsyndromic Cleft Lip with or without Cleft Palate in Two Multiplex Families in Shenyang,China

Objectives To identify the loci involved in nonsyndromic cleft lip with or without cleft palate （NSCL/P） in Northern Chinese people in Shenyang by using genomewide and interaction linkage scan.Methods Two multiplex families in Shenyang from North China were ascertained through probands with NSCL/P.Blood of every member was drawn for DNA extraction and analysis.Genotypes were available for 382 autosomal short tandem repeat （STR） markers from the ABI Prism Linkage Mapping Set version 2.5.Linkage between markers and NSCL/P was assessed by 2-point parametric LOD scores,multipoint heterogeneity parametric LOD scores （HLODs）,and multipoint nonparametric linkage score （NPL）.Results The initial scan suggested linkage on Chromosomes 1,2,and 15.In subsequent fine mapping,1q32-q42 showed a maximum multipoint LOD score of 1.9（empirical P=0.013） and an NPL score of 2.35 （empirical P=0.053）.For 2p24-p25,the multipoint NPL increased to 2.94 （empirical P=0.007）.2-locus interaction analysis obtained a maximum NPL score of 3.73 （P=0.00078） and a maximum LOD score of 3 for Chromosome 1 （at 221 cM） and Chromosome 2 （at 29 cM）.Conclusion Both parametric and nonparametric linkage scores greatly increased over the initial linkage scores on 1q32-q42,suggesting a susceptibility locus in this region.Nonparametric linkage gave a strong evidence for a candidate region on chromosome 2p24-p25.The superiority of 2-locus linkage scores compared to single-locus scores gave additional evidence for linkage on 1q32-q42 and 2p24-p25,and suggested that certain genes in the two regions may contribute to NCSL/P risks with interaction.

Lateral Crus Graft with Autologous Rib Cartilage for Cleft Lip Nostril Asymmetry: A Report of 35 Cases

Summary： A surgical technique of lateral crus strut graft to correct the deformity of nostril contour and improve asymmetric nostril shape by autologous rib cartilage was reported. Thirty-five patients （20 males and 15 females）, with a mean age of 19 years （range of 16-26 years） were included in this study. All of the patients suffered moderate to severe unilateral cleft lip nostril deformity and underwent surgical technique of lateral crus strut graft by autologous rib cartilage to correct the asymmetric nostril contour from 2010 to 2012. The views of the nostril contour on both sides were reviewed and some parameters were measured at different time points （preoperatively, and 3 months and one year postoperatively） including the long axis and short axis of the nostrils. The differences in nostrils including long axis, short axis, elliptical area and eccentricity on the both sides were compared at different time points. The differences in the long axis and eccentricity of the nostrils on the two sides were decreased significantly between the preoperative view and postoperative view （P〈0.05）. The surgical technique of lateral crus graft with autologous rib cartilage is effective to correct the abnormal nostril contour and improve the asymmetry for unilateral cleft clip patients.

Repair of the Median Microform Cleft Lip Using Z-Plasty

A median cleft lip is a rare central midline deficiency of the upper lip. Multiple surgical techniques are described in the literature to address this defect, though there is little consensus on the preferred surgical technique. We describe an intra-oral approach for repair of the median upper lip cleft using mucosal Z-plasty. This technique provides excellent access to the attenuated orbicularis oris muscle and the frenulum fibrosed to the labial margin. The tethered lip can be mobilized and the notch converted with appropriate mucosal length, lip height, and vermillion fullness. The contour of the free labial border immediately improves, all while avoiding a cutaneous scar. The midline cleft lip notch can be effectively treated by adhering to 3 major principles: 1) excision of the tight, constrictive labial band;2) achieving midline orbicularis oris muscle approximation;and 3) establishing mucosal lengthening using a Z-plasty.

A Case-control Study of Environmental Risk Factors for Nonsyndromic Cleft of the Lip and/or Palate in Xuzhou,China

In this study, we sought to determine the association between environmental factors and nonsyndromic cleft of the lip and/or palate （NSCLP） to understand the etiology of the disease. A total of 200 NSCLP cases and 327 controls were recruited at the Maternal and Child Health Hospital of Xuzhou City. We conducted face-to-face interviews with the mothers of both cases and controls. The factors increasing the risk of NSCLP were a positive family history [odds ratio （OR）=56.74], pesticide exposure （OR=8.90）, and indoor decoration pollution （OR= 4.32）. On the other hand, the factors decreasing the risk of NSCLP were a high education level （OR=0.22） and supplementation of folic acid （OR=0.23） and multivitamins （OR=0.16）. Positive family history, pesticide exposure, and indoor decoration pollution are associated with the risk of NSCLP. In contrast, high education level and folic acid and multivitamin supplementation are protective factors against NSCLP.

Comparison of Congenital Tooth Deficiencies Seen in Permanent Teeth in Individuals with Unilateral Cleft Lip and Palate to Those without Cleft Lip and Palate

Objective: To compare the congenital tooth deficiencies seen in permanent dentition in individuals with unilateral cleft lip and palate (UCLP) to non-cleft individuals with Angle Class I malocclusion. Method: The study was performed on orthopantomograph films of 50 individuals with UCLP aged between 12 - 16 years and 50 individuals with Angle Class I malocclusion individuals aged between 13 - 15 years. Individuals with UCLP;32 clefts were on the left side and 18 clefts were on the right side. Permanent third molar teeth deficiency was excluded from the study. Results: In 50 individuals with UCLP;35 (70%) upper lateral incisors were congenitally deficient in the cleft area, while 15 (30%) missing lateral teeth were found in the non-cleft side. In control group, 12 (24%) of 50 patients had congenital lateral incisor deficiency. Congenital deficiency of upper lateral incisor in UCLP;the cleft area was higher than the non-cleft side (p < 0.01). The difference was statistically important when compared with the control group (p < 0.001). In 50 individuals with UCLP;while 27 (54%) of second premolar teeth were congenitally deficient in cleft side, 23 (46%) were missing in non-cleft side. In control group, 18 (36%) congenital second premolar deficiency was detected. However, second premolar congenital deficiency was higher in UCLP group when compared to control group (p < 0.01). Conclusion: The deficiency of the lateral incisors in the cleft side is more often congenitally deficient than upper second premolar teeth and this should be considered in the treatment planning from an early age.

Updating Genetics Polymorphisms of Non-Syndromic Clefts Lip-Palates

Introduction: Non-Syndromic Clefts Lip-Palates (NSCLP/CP) are most common congenital malformation in the world, with very important psychic and social impact. Formation of NSCLP/CP arises from the interaction of environmental and genetic factors. This paper provides a review of recent progress in defining the genetic causes of NSCLP. Methods: A literature review was conducted on the Medline data by searching for the following keywords: genes, non-syndromic cleft lip-palate, and genetics of clefts lip-palates, until January 2018. Results: Various genes are identified in different population and country, with the study using case parent’s trio. The aim of this study contributes to review relative gene which has been identify in non-syndromic cleft lip and palate, and to help to have a better understanding of the inheritance pattern of this pathology and the prevention of genetic disease. Conclusion: Although three major genes have been confirmed, the genetic research is necessary to provide an understanding of the pathophysiology of the clefts lip-palates.

Evaluation of Maxillary Dental Arch Widths in Individuals Having Unilateral and Bilateral Cleft Lip and Palate Using Three-Dimensional Digital Models

Aim: Maxillary dental arch widths were evaluated in individuals having unilateral (UCLP) and bilateral (BCLP) cleft lip and palate (CLP) using three-dimensional (3D) digital models. Material and Method: The study had been conducted on 80 individuals aged between 14 - 17 years having UCLP and BCLP. 40 of the individuals had UCLP, whereas 40 had BCLP. The maxillary dental models taken from patients before the treatment were scanned using Orthomodel Programme (v.1.01, Orthomodel Inc., Istanbul, Turkey) to obtain 3D imagery. Student’s t-test was used in order to assess the data obtained by using SPSS software version 22.0. Results: In BCLP, the average inter-canine distance was 17.44 ± 1.31 mm, the average inter-molar distance was 36.57 ± 1.12 mm, while inter-canine/inter-molar ratio was 0.47. Whereas in UCLP, it was 25.10 ± 0.63 mm, 42.20 ± 0.53 mm and 0.59. The inter-canine distance in UCLP was found to be large enough to be statistically significant (p 0.05), even though there were differences in inter-molar widths. Conclusion: For the stable orthodontic treatment results, one of the most important points is arch form and widths to be coherent with each other. In our study, the increase of inter-canine distance seen in UCLP indicates that in the cleft region, the maxillary arch is inclined over to the back, while the same situation in BCLP suggests that the maxillary segments are collapsed inside. The difference in the arch is highly affected by the primary surgical treatment.

Cleft Lip Surgical Intervention in Resource Constraint Settings: A Case Report

Cleft lip and palate is a very common condition which is globally undertreated. This case report shows how cleft lip surgery can transform patient’s lives, self-perception, and their self-esteem through a visionary and adaptive leadership of a few social workers and medical doctors in resource constrained settings. The case report also shows that when treated, the benefits to the patient and their family are lifelong and disproportionately large compared to the degree of effort and cost of doing the reconstruction;and puts forth the case for educating physicians to maximize their societal benefit through work in resource-constrained settings.

Orthognathic Surgery for Achieving Facial Balance and Harmony in Cleft Patients

Cleft surgery requires an expert team performing ongoing treatment in order to achieve optimal outcomes. The senior author's(KES) experiences of more than 2000 patients with cleft lip and palate treated by a surgical-orthodontic protocol were introduced. The paper here will concentrate on not only correcting the occlusion as others have described,but also on what one surgeon can do to achieve optimal aesthetic balance, harmony and beauty. The results of orthognathic surgery in respect to function, stability, cosmesis, and complications are also audited.

Gastroschisis Associated with Cleft Lip and Palate: Report of Three Cases

Gastroschisis is a malformation of the abdominal wall like omphalocele. In most cases, gastroschisis is isolated. But in some cases, we find malformations, essentially minor and concern gastrointestinal or genitourinary systems. Association with craniofacial congenital midline defects is uncommon. We report 3 cases of association between gastroschisis and cleft lip and palate for the benefit of the scientific community. Two 0-day-old and a 1-day newborns were admitted in our institution for malformation of face and abdominal wall. The physical examination confirmed the association of gastroschisis and cleft lip and palate. The patients underwent primary closure. Other malformations could not be sought until all patients died.

Stability of maxillary advancement using external rigid distractors in cleft lip and palate patients

Purpose: To evaluate the skeletal changes associated with maxillary advancement using the external rigid distractor in cleft lip and palate patients after distraction and to assess the stability of these changes. Patients and Methods: Eight cleft lip and palate patients with maxillary hypoplasia underwent maxillary distraction osteogenesis using external rigid devise. Lateral cephalometric records were obtained before distraction T1 and after completing active distraction T2. After a three month follow up period a final lateral cephalometric record was evaluated T3. Results: The maxilla was significantly advanced as indicated by the increase in maxillary depth angle and effective maxillary length (median difference, 10 mm). The palatal plane angle showed a significant increase (median difference, 5o), showing clockwise rotation. At T3 there was a slight decrease in maxillary depth angle (median difference, 3o). Effective maxillary length decreased significantly at T3 (median difference, 2 mm). The palatal plane angle decreased (median difference, 3o) and almost returned to its original position, showing a counterclockwise rotation. Conclusion: Maxillary advancement using external rigid distractor resulted in clockwise rotation of maxilla with increase in palatal plane angle and slight increase in mandibular plane angle. The amount of maxillary advancement was slightly reduced during follow up and the palatal plane almost returned to its original position. These changes showed good stable clinical results.

A protocol used to manage maxillary hypoplasia in cleft lip and palate patients

Objectives: We report our experience and the protocol we used in managing maxillary hypoplasia in cleft lip and palate patients. Patients and methods: 14 adult cleft lip and palate patients with maxillary hypoplasia were evaluated clinically. Dental models and radiographs including (lateral cephalograms and orthopantographs) were obtained at the initial visit and upon completion of the presurgical orthodontic treatment. Patients with occlusal discrepancies larger than 6 mm and severe palatal scaring underwent Distraction osteogenesis (DO) to advance the maxilla. Patients with an occlusal discrepancy of 6 mm or less, underwent traditional orthognathic surgery including le fort I advancement and Bilateral sagittal split osteotomy (BSSO) to seat the mandible in occlusion. Results: Five patients underwent orthognathic surgery. Two of them underwent double jaw surgery. Three underwent single jaw conventional le fort l advancement. Four patients required bone grafting to repair the residual alveolar defect and to augment the midface deficiency. Nine patients with severe maxillary hypoplasia underwent maxillary advancement using distraction osteogenesis. Conclusion: Patients with a severe maxillary hypoplasia of 6 mm or more and excessive palatal scaring are successfully treated with DO. Conventional le fort I is reserved for patients with less severe maxillary hypoplasia. Both techniques gave promising results providing having followed the proper selection criteria.
