[Epidemiology and treatment of sinus mucoceles: 25 cases in Abidjan (Côte d'Ivoire)].

Objective: To determine the epidemiological, clinical and therapeutic characteristics of sinus mucoceles in Ivory Coast.

Materials And Methods: A multicenter study conducted in the three services ENT (ear, nose & throat) hospital and university centers and clinics in Abidjan from 1996 to 2012 (16 years). It involved patients who have been diagnosed clinically and radiologically with a sinus mucocele who benefited from surgical treatment.

Results: During the study period, 25 patients were recruited - a hospital incidence of 1.5 cases per year. A female predominance was noted with 60% of women and 40% men with a sex ratio of 0.67. Patients consulted for headache (68%), facial swelling (68%), proptosis (28%). Allergic rhinitis is the antecedent rhinologic found most commonly (32%) followed by sinusitis (12%) and nasal sinus surgery (12%). The naso-sinus CT was performed in all patients diagnosed with mucocele. Surgical excision was made by several surgical approach, the most used were the way of JACQUES and paralateronasal rhinotomy of MOURE. Pathological examination of the surgical specimen confirmed the diagnosis of sinus mucocele. The development was beset by complications such as eyelid swelling (1 case), blurred vision (1 case), unsightly surgical scar (1 case).

Conclusion: The nasal sinus mucoceles are relatively rare benign lesions with pseudo-cystic insidious evolution. Diagnosis suspected by the clinic is confirmed by radiology. Their treatment is mainly surgical.
