[Cervicofacial cellulitis of dental origin: etiology, epidemiological and therapeutic aspects]. / Aspects étio-épidémiologiques et thérapeutiques des cellulites cervico-faciales d'origine dentaire.

OBJECTIVES: Cervicofacial cellulitises are dominated by dental affections. The aim of this study is to describe etio-epidemiological and therapeutic aspects of cervicofacial cellulitis of dental cause at the CNHU-HKM in Cotonou (Benin). METHODS: It's a retrospective study from 1998 to 2007 included patients with inflammatory cervicofacial tumefaction of dental cause. A glycaemia, a HIV serology and a blood formula numeration are realized. Some patients practiced standard oral and dental radio. Patients were hospitalized and received mono, bi or triple antibiotic. Lancing with swab of pus for cytobacteriological and antibiogram examination was realized for some of patients. Dental cares were been systematic. RESULTS: 68 cases whose 53 dental cause where been collected 77.94%. Bracket concern patients between 0-20 and 20-40 years old (64.15%). Males were, more concerned. Dental traumatisms find again (18.88%), tooth decay (56.60%) and 24.53% patients practiced dental extraction. Anti inflammatory practiced by 67.92% patients associated to antibiotic in 41.51% cases. The three latest molar were concerned to 26 patients. Among those last 22 had attack of mandibular teeth. Treatment consisted in lancing drainage to 2/3 patients in 83.40% cases associated to tri antibiotic. Evolution has been favourable with recovery to 86.67%; 6 decreases to 13.33% cases. CONCLUSIONS: Cervicofacial cellulitises are dangerous, rapidly responsible of deceases by extension. A better oral and dental hygiene would improved prognosis.

[Seven cases of inverted nasosinusal papilloma treated at Cotonou]. / Sept cas de papillome inversé nasosinusien pris en charge à Cotonou.

OBJECTIVE: Sinonasal inverted papilloma is a rare benign tumor with a high recurrence rate and potential malignant transformation. The purpose of this study was to analyze the clinical and radiological aspects and to identify the suitable surgical approaches to be used in developing countries. METHODOLOGY: In 3 years, 7 cases have been analyzed in a retrospective study. Patients presented with unilateral nasal obstruction and epitasis, a whitish unilateral polypoid mass, sinonasal opacity with osteolysis on CT scan or on sinus X-ray. Using these data we adopted the Krouse staging which classifies the disease in four stages and accordingly the appropriate surgical approach was used. The diagnosis was confirmed by histological examination of the biopsied specimen. RESULTS: Average age 48.28 years, predominant sex male. Symptom: unilateral nasal obstruction 5, bilateral nasal obstruction 1, epistaxis 5. The average time-delay before consultation was 73 months. The combined endonasal endoscopic and vestibular was the most commonly used approach (4 cases). The results were satisfying. After a minimal follow up of 2 years, one case of recurrence was detected after 4 years. CONCLUSION: CT scan is an essential tool for the diagnosis and detecting the extension of sinonasal inverted papillomas. Better results were obtained with a surgical approach that combined a vestibular approach and an endonasal endoscopic approach in our region.
