Objective: This study aimed to describe anatomic variants of sphenoidal sinuses and adjacent structures. Methods: A retrospective and descriptive study was carried out at The National and University Teaching Hospital Hubert Koutoukou Maga (CNHU-HKM), of Cotonou in Benin from November 1st to December 31st. A review of CT scans skull was done for the subjects aged at least 16 years old. Anatomic variants of the sphenoid sinuses and adjacent structures have been investigated. Results: 225 CT scans of skull were analyzed. The sellar type was the most common type of pneumatization of sphenoid sinuses (74.7%). Pneumatization of anterior clinoid processes of greater and lesser wings of the sphenoid and of pterygoid processes was observed in 7.1%; 4.6%; 3.3% and 7.3%; respectively. Protrusion of carotid canals and optic canals, maxillary and vidian nerves were observed in 48.3%; 13.1%; 18% and 9.5%; respectively. Conclusion: Risky anatomic variants of the sphenoid sinuses and adjacent structures are also described by CT-scan among Beninese. Before any surgery and to avoid bad outcome, a precise approach of these risky anatomic variants must be carried out by using CT-scan.
Introduction: Damage to the nasal cavities and sinuses of the face concern many disciplines, especially the specialist in Otorhinolaryngology and Cervical-Facial Surgery (ENT-CFS), since most symptoms have little value to direct the patient towards a precise diagnosis, radiological exploration, including three-dimensional imaging, provides diagnostic, therapeutic and follow-up support. The aim is to study the clinical and computed tomography scan aspects of non-traumatic chronic nasosinusitis disorders at the Teaching University Hospital of Hubert Koutoukou Maga (CNHU/HKM) in Cotonou. Material and Method: It was a descriptive and analytical study with retrospective collection, carried out over a period of 36 months from January 1st, 2014 to December 31st, 2016; on 261 files of patients seen in Otorhinolaryngology (ENT) and Cervico Facial Surgery (CFS) consultating for a chronic nasosinusitis disorder with no trauma notion and having performed a CT scan. Results: Chronic lesions of the nasal sinus cavities accounted for 13.42% of ENT consultations. There was female predominance with a sex ratio of 0.85. The clinic varied, the most common signs were rhinorrhea (74%), headache (73.6%) and sneezing (38.3%). On computed tomography scan, 225 results were pathological. Sinus backfilling was in the lead with 66.7% followed by mucous thickening with 60.44%, and by bone involvement in 28%. Inflammatory pathologies (82.22%
