Sinonasal Polyposis: About 60 Cases at Fann University Hospital Center, Senegal

Introduction: Sinonasal polyposis (SNP) is a chronic inflammatory disease of the mucosa of the nasal cavities and facial sinuses. It is characterized by an oedematous, multifocal and bilateral degeneration of the nasosinus mucosa, which originates in the lateral masses of the ethmoid, where it causes the formation of smooth, gelatinous, translucent and pyriform polyp lesions. The objective of this study was to review epidemiological, clinical, paraclinical data and evaluate the results of endoscopic surgical treatment. Patients and Methods: This is a retrospective study on 60 patients followed at the ENT department of the Fann National University Hospital Center, from January 2010 to December 2015. All patients with sinonasal polyposis were included in the study. Results: The average age of our patients was 38 years and the sex ratio (M/F) was 0.8. In the patients’ histories, we found 18% asthma and 10% Widal’s disease. The average consultation time was 8.5 years. All patients had consulted for nasal obstruction;rhinorrhea was bilateral and found in 67.7% of cases, with olfactory disorders accounting for 50%. The CT scan performed in 58% of cases made it possible to specify the extent of the lesions;the involvement of the ethmoidal sinus was constant and extended to the other sinuses except in 2 cases. All patients had received medical treatment with local corticosteroids. Endoscopic surgical treatment was initiated in 43% of cases after failure of corticosteroid-based medical treatment. The evolution under treatment marked by the reappearance of symptoms that increased each month. At one month postoperatively, all clinical symptomatology had improved with the exception of olfactory disorders, which persisted in 3 patients. At 12 months we noted 12 cases of reappearance of nasal obstruction. Conclusion: SNP is a disease of little known etiology. The diagnosis is almost always clinical. Endoscopic surgery remains a recourse to medical treatment. For good local control, patients should be more respectful of good compliance with corticosteroid therapy.

Endoscopic endonasal intraconal orbit surgery

Endoscopic endonasal orbital surgery is evolving.With increasing knowledge,expertise,and technology,the historical limits of the endonasal endoscopic approach to the orbit have been redefined.This review discusses the clinical presentation and etiology,and highlights the pertinent anatomy,and discusses the diagnostic workup and surgical approach to orbital tumors and post-operative care.The role of the multidisciplinary team is not to be underestimated.The introduction of a classification system to ensure standardization of technical difficulty and outcome data will assist with international collaboration and further consolidate our attainment of knowledge in this developing field.

Does reconstruction affect outcomes following exclusively endoscopic endonasal resection of benign orbital tumors: A systematic review with meta-analysis

Objective:As exclusively endoscopic endonasal resection of benign orbital tumors has become more widespread,high-quality outcomes data are lacking regarding the decision of when and how to reconstruct the medial orbital wall following resection.The goal of this study was to systematically review pertinent literature to assess clinical outcomes relative to orbital reconstruction practices.Methods:Data Sources:PubMed,EMBASE,Web of Science.A systematic review of studies reporting exclusively endoscopic endonasal resections of benign orbital tumors was conducted.Articles not reporting orbital reconstruction details were excluded.Patient and tumor characteristics,operative details,and outcomes were recorded.Variables were compared usingχ^(2),Fisher’s exact,and independentt tests.Results:Of 60 patients included from 24 studies,34(56.7%)underwent orbital reconstruction following resection.The most common types of reconstruction were pedicled flaps(n=15,44.1%)and free mucosal grafts(n=11,32.4%).Rigid reconstruction was uncommon(n=3,8.8%).Performance of orbital reconstruction was associated with preoperative vision compromise(P<0.01).The tendency to forego orbital reconstruction was associated with preoperative proptosis(P<0.001),larger tumor size(P=0.001),and operative exposure of orbital fat(P<0.001)and extraocular muscle(P=0.035).There were no statistically significant differences between the reconstruction and nonreconstruction groups in terms of short-or long-term outcomes when considering all patients.In patients with intraconal tumors,however,there was a higher rate of short-term postoperative diplopia when reconstruction was foregone(P=0.041).This potential benefit of reconstruction did not persist:At an average of two years postoperatively,all patients for whom reconstruction was foregone either had improved or unchanged diplopia.Conclusion:Most outcomes assessed did not appear affected by orbital reconstruction status.This general equivalence may suggest that orbital reconstruction is not a necessity in these cases or that the decision to reconstruct was well-selected by surgeons in the reported cases included in this systematic review.
