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.展开更多

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.展开更多
