Purpose of the work: to study the epidemiological, clinical and therapeutic aspects of diffuse cervico-facial cellulitis collected within the ENT-CCF surgery department of the CNHU of Cotonou. Materials and method: the study was a descriptive retrospective carried out from January 1 st , 2018 to December 31 st , 2020. It concerned new cases of diffuse cervico-facial cellulitis identified during the period. Results: in 3 years, 55 cases of diffuse cervico-facial cellulitis were identified out of 1101 hospitalized patients. The frequency was 4.99%. Per year, 18 cases of cervico-facial cellulitis are recorded. The mean age of the patients was 41.3 years with extremes of 15 years and 85 years. A clear male predominance was noted with a sex ratio of 1.29. Painful cervico-facial swelling was the most common reason for medical consultation (47 patients or 85.5% of cases). Thirty patients (54.5%) showed a deterioration in general condition. Several clinical forms of diffuse cervico-facial cellulitis have been described, in particular the gangrenous form, the suppurative, necrotizing form and LUDWIG's angina. The portal of entry was dental in 50 patients (91% of cases), favored by poor oral hygiene and self-medication with non-steroidal anti-inflammatory drugs (NSAIDs). The medico-surgical treatment implemented was favorable for 47 patients (85.5%). Conclusion: Diffuse cervico-facial cellulitis remains a frequent medical-surgical emergency in the CCF ENT department at the Teaching Hospital of Cotonou. Mainly of odontogenic origin, it is encountered in different clinical forms.

Wood dust may induce health risks on exposed timber or wood workers, one of which is ENT disorders. This article aimed to detect ENT pathologies found among woodworkers in Parakou. It was a cross-sectional descriptive study carried out from 1 st March to 31 st May, 2012 in Parakou, NorthBenin. It involved 703 carpenters and sawyers operating in timber workshops in Parakou, regardless of age and sex. The mean age of the wood-workers was 26.14 ± 7.77 years. Their seniority in the timber profession was on average 4.9 ± 2.64 years. All of them were males. It had been noticed that 81.6% of them did not comply with any safety measure for their protection. ENT pathology had been diagnosed in 60.3% of the timber workers. Rhinitises came first and affected 43.1% of the workers, followed by pharyngitises (14.1%). The histological nature of the only case of tumor observed in Parakou could not have been specified, as the patient refused to undergo anatomopathological examination. Measures should be taken to get Parakou timber workers to protect themselves.

Introduction: Acute otitis media (AOM) is one of the most common ENT childhood diseases. Objective: To identify risk factors for AOM in children aged 0 to 5 years. Methods: This research work was a cross-sectional, descriptive and analytical study. It focused on 2040 children aged 0 to 5 years from both sexes, who were healthy or sick, and living in the Local government of Parakou for at least one year. Those children were randomly selected in all three districts of Parakou. Results: Frequency of AOM was 2.8% and their prevalence was estimated at 16.3%. The identified risk factors were persistent or chronic cases of rhinitis, exposure to charcoal and wood smoke, low socioeconomic status, personal history of AOM, AOM history among the siblings, and children's poor nutritional status. No relationship could be established between AOM occurrence and factors like sex, passive smoking, attendance of a day-care centre or stay in nursery, prematurity, exclusive breastfeeding and large number of siblings. Conclusion: The identification of those risk factors will help put in place appropriate measures to reduce AOM prevalence in Parakou.

The aim of this study was to contribute to the improvement of the management of the condition in sub-Saharan Africa.

It involved all patients who consulted during the study period and in whom the diagnosis of acute maxillary rhinosinusitis was made. Results: A total of 405 cases were identified. The mean age was 34.26 ± 15.26 years with extremes of 9 and 63 years. The predominance was female with a sex ratio of 0.61. Acute maxillary rhinosinusitis was bilateral in 371 cases (91.60%). The main symptoms were facial pain in 346 cases (85.43%), mucopurulent rhinorrhea: 315 cases (77.78%), headache: 283 cases (69.88%), and nasal obstruction: 244 cases (60.25%). The most frequent physical signs were pain on pressure of the maxillary sinus points in 405 cases or 100%, purulent secretions at the middle meatus: 11.35%, hyperemia of the nasal mucosa: 53.58%, hypertrophy of the middle turbinate: 41.48% and discharge of pus on the posterior pharyngeal wall: 36.79%. Amoxicillin + clavulanic acid was the main antibiotic prescribed. Vasoconstrictors were used in 228 cases 56.30%. The evolution was favorable in all cases. Conclusion: The diagnosis of acute maxillary rhinosinusitis is clinical. Treatment with antibiotic gives good results.
