Introduction: Fallopian diseases are often implicated in female infertility. Several radiological and surgical explorations have been proposed in order to evaluate the severity of lesions found in utero-adnexal pathology. Among tools that are used to investigate such pathologies, we have ultrasound, hysterosalpingography and endoscopy. But, in many developing countries like Cameroon, the usage of endoscopy in gynecology is not yet known by many practicians. The objective of our study was to show the interest of endoscopy in the diagnosis of fallopian tube pathologies. Methodology: We conducted a cross-sectional and descriptive study from March 1st, 2017 to May 31st, 2017 at the Gyneco-Obstetrics and Pediatric department of our Hospital. We included all women who presented infertility and underwent ultrasound, hysterosalpingography (HSG) and endoscopy at the Yaoundé Gyneco-obstetrics Hospital. We analyzed epidemiological parameters, clinics, ultrasound, hysterosalpingography and endoscopic finding. We used Cohen’s Kappa test to determine the correlation between HSG/endoscopy and ultrasound/endoscopy in the diagnosis of fallopian tube pathologies. The threshold was significant for a K-value > 0.20. Results: We got a sample of 156 women;the mean age was 32.6 ± 4.5 years. The Secondary infertility dominated in 66.7% of cases;31.1% of women presented a past medical history of sexually transmitted infections and 41.7% did abortions before. Endoscopic lesions were dominated by a fallopian obstruction in 54.5% of cases, 8.3% of adhesions, 33.9% of women presented uterine myomas, 37.8% of ovarian cysts and 1.3% of pelvic endometriosis. The K-values between HSG and endoscopy for distal and proximal tube obstructions were significant with respective thresholds of 0.25 and 0.30. The K-value between ultrasound and endoscopy was not significant with a threshold of 0.015 for the tubal hydrosalpinx. Conclusion: Endoscopy assessment appears as the most efficien

Introduction: Endoscopic endonasal surgery is currently a validated therapeutic modality in most nasal sinus disorders. In developed countries, this practice is common and sees the indications constantly reviewed;In sub-Saharan Africa, this surgical technique is popularized. The external pathways are morbid and not very functional. In our daily practice at the Yaounde General Hospital (YGH), this technique is still in its infancy. Gradually it’s entering our habits and sees its indications increases. Through this study, we are reporting readily available data from our experience. Objectives: The objective was to study the practice of endoscopic endonasal surgery in our setting. Patients and Method: This was a cross-sectional, descriptive, retrospective study. The site of study was the ear-nose and throat service of Yaounde General Hospital. The study was conducted from January 2013 to December 2020, for an 8 years basis. The sampling was consecutive. We included in this study all patients operated on for a nasal sinus disease by the endoscopic endonasal modality. We excluded patients with incomplete files, as well as those who had a complementary transfacial approach during the same operation. The data were collected on prepared questionnaire. Data analysis is done with ssps 23.0 software. Results: We recruited 30 cases, out of a total of 330 interventions carried out in our department. The prevalence of this surgery in our activity was 9%. Male and female had equal ratio of 50%. The most represented age group was 30 - 40 years (33.3%). All the patients had a facial sinus CT scan, we did not note any anatomical variant as risk. Two patients of our sample size had a history of sinus surgery, treated externally. Chronic maxillary sinusitis was the surgical indication in 36.7%, followed by Killian antro-choanal polyps in 13.3%, nasosinus polyposis in 13.3% and all performed under general anesthesia. Th

Introduction: Deafness, is the most common neurosensory deficit in humans. The origins can be diverse: congenital or acquired and sometimes of an etiology that is difficult to specify. The main risk is social exclusion. The advent of cochlear implants is a solution of choice for severe to profound sensorineural hearing loss. This innovative therapeutic modality is new to Cameroon, so we proposed to evaluate the preliminary results of cochlear implantation at the General Hospitals of Yaoundé and Douala, by addressing the epidemiological, clinical and paraclinical, surgical, and prosthetic aspects. Methodology: We conducted a descriptive and prospective cross-sectional study over a period of two years and eight months, from January 2019 to 31 August 2021. The study sites were: the general hospitals of Yaounde and Douala, as well as the private practices of speech therapists in the said cities. We collected socio-demographic, clinical, paraclinical variables and data on surgical, prosthetic and speech therapy management which were processed. Results: We recruited 15 cochlear implant patients, one adult and 14 children. The sex ratio was 1.14 in favour of girls, the average age of the child population was 4.9 years and one subject was 57 years old. These children were mostly in school (85.7%) and mostly (86.7%) living in urban areas. The average period of sound deprivation was 3.9 years. The deafness of the children was 100% prelingual and the acquired cause was evoked in front of the risk factors (prematurity, low birth weight, neonatal asphyxia, jaundice, meningitis, neuromalaria) for 57.7% of them. The adult deafness was postlingual and post-traumatic. The associated clinical conditions found in 4 (26.8%) of the patients were an ocular refraction disorder, a chronic otitis media sequelae, cerebral palsy and minor head trauma injuries. There was no syndromic or malformative picture. The deafness was bilateral in all cases, asymmetric in 22.2% of cases and severe to pr

Introduction and Aims: Pharyngostoma or pharyngo-cutaneous fistula is a frequent complication of totals laryngectomies and pharyngo-laryngectomies. Its incidence varies from one series to another from 13% to 58%. Multiple risk factors are known. The data from our environment concerning this condition are few. Thus, in order to contribute to the study of this complication in our environment, we proposed to carry out this study, whose objective was to determine the predictive factors for the occurrence of pharyngo-cutaneous fistula or pharyngostoma after total laryngectomy and total pharyngo-laryngectomy in Yaounde and Douala. Patients and Methods: This was a retrospective, cross-sectional, descriptive study conducted in the 5 Ear-Nose-Throat (ENT) department of hospital in the city of Yaounde and Douala. The study took place between January 2009 and December 2020. All patients who underwent total laryngectomy or total pharyngo-laryngectomy with a follow-up of at least one month were included in the study. Incomplete records were excluded, as well as those of patients who died before one month of postoperative follow-up. Results: We selected 48 cases of total laryngectomies (TL) and total pharyngo-laryngectomies (TPL), and identified 37 cases of pharyngostoma. 45 men (93.8%) and 3 women (6.3%). The mean age was 56.4 years with extremes ranging from 37 to 86 years. Smoking and alcoholism were noted in 75% and 79.2% of our patients respectively. A tracheotomy before TL and TPL was found in 41.7%. 100% of the tumours found were T3 or T4. The surgery was in 34 cases (70.8%) TL and in 14 cases (29.2%) TPL. Pharyngostomas were observed in 37 cases among 48 patients operated on, i.e. a frequency of 77.1%. The average delay of appearance was 7 to 14 days. We had spontaneous healing with pressure dressing and nasogastric tube feeding in 35 patients (77.8%) and two patients benefited from pectoralis major flap treatment;the healing time was 21 to 30 days. We did not find any co
