Maxillary sinusitis: 1752 cases at the ear-nose-throat department of a teaching hospital in Cotonou, Benin.

OBJECTIVE: Maxillary sinusitis is a frequent ear-nose-throat (ENT) infection. The purpose of this study was to determine the prevalence of maxillary sinusitis in the ENT department of a teaching hospital in Cotonou, Benin, and to report the clinical findings, together with the results of complementary examinations and treatment outcomes. PATIENTS AND METHODS: This was a retrospective descriptive analysis of patients seen at our hospital from January 1, 2004 to December 31, 2008 for maxillary sinusitis. RESULTS: Over the 5-year study period, 1752 cases of maxillary sinusitis were treated in the ENT department of the teaching hospital, which works out to 350 or 351 cases per year. The overall prevalence was 19.3%. There were 759 patients (83.1%) aged 16-50 years, and 984 patients (56.2%) were men. Factors favoring maxillary sinusitis were: dry season with dust (n=1051 patients, 60%); and atmospheric pollution (87.6%). Maxillary sinusitis was acute for 528 patients (30.1%) and chronic for 1224 patients (69.9%). A rhinogenic cause was identified for 960 patients (54.8%), an allergic cause for 668 patients (38.1%) and a dental cause for 96 patients (55.5%). In cases of chronic sinusitis, the infection was predominantly staphylococcal (29.3%) and pneumococcal (21.9%). Basically, medical treatment was given by combining local treatments for rhinopharyngeal disinfection or vasoconstriction. In cases with a dental origin, dental care was also delivered. For allergy-related sinusitis, nasal sprays with corticosteroids and antihistamine agents were prescribed. Outcomes were favorable for 89.7% of patients.

[Imflammatory myofibroblastic tumour of nose and paranasal sinuses in a little girl of 7-year-old]. / Tumeur myofibroblastique inflammatoire endonasale chez une fillette de 7 ans.

Inflammatory myofibroblastic tumours (IMTs) are clinical and pathological distinct entities with controversial biological entities. IMTs have been described in the lungs, abdomen, retroperitoneum and extremities but rarely in the head and neck region. This case report corresponds to an IMT of the nose and the paranasal sinuses in a little girl of 7 years of age. The computed tomography scan showed an expanding tumoral process without skull destruction. First case report in the west African region, this observation describes the treatment instituted according to the possible care in our medical area, and the treatment when the patient was referred to a centre with efficient technical platform. This case underlines the aggressiveness of this type of tumour: an invasive tumour with local-regional extension and high recurrence potential. Currently, after 2 years, the tumoral process is considered cured after several radical surgical excisions.
