[Contribution of the musculocutaneous flap of pectoralis major in head and neck oncology: 26 observations in Senegal]. / Apport du lambeau musculo-cutané du pectoralis major en carcinologie cervico-faciale: 26 observations au Sénégal.

INTRODUCTION: The pectoralis major musculocutaneous flap constitutes a significant advance in cervicofacial carcinology. At our institution, it has allowed most surgical problems to be resolved in a single-stage procedure. The objective of this study was to report our experience with this flap. PATIENTS AND METHODS: This retrospective study includes 26 cases observed over a 10-year period (January 1994-December 2003). The parameters studied were clinical and paraclinical. All patients included in this study received a pectoralis major musculocutaneous flap. Patients treated using another type of flap were not included. RESULTS: Mean patient age was 51 years (range, 20 to 74). The sex ratio was 12 (24 men and 2 women). At the time of admission, 73% of patients showed marked impairment of general condition. In 21 patients (81%), the effect of the pectoralis major musculocutaneous flap was observed immediately after surgery unlike pharyngostome (19%) in which the flap is used in a second stage procedure. With a mean follow-up of 7 years, failure has been observed in 4 cases (15%). CONCLUSION: The pectoralis major musculocutaneous flap is an excellent tool for cervicofacial reconstruction after carcinological exeresis. It reduces the duration of hospitalization. Acquiring proper flap harvesting technique is an important factor in improving outcome.

Laryngeal Papillomatosis in Adults: Assessment for Ten Years at the ENT Department of the National University Hospital of Fann (Dakar, Senegal).

OBJECTIVES: The aim of this study was to describe the epidemiological, diagnostic, and therapeutic aspects of adult laryngeal papillomatosis in Senegal. Patients and Methods. This is a retrospective descriptive study of patients aged above 18 years with laryngeal papillomatosis and followed at the ENT department of the NUH of Fann between 01 January 2009 and 31 December 2018. RESULTS: The mean age at diagnosis was 37.74 years and a sex ratio of 0.93. The 20-29 age group was the most represented (45.2%). The average consultation delay was 8.34 years. All patients had dysphonia at the moment of the diagnostic and in 35.5% of cases, and it was associated with laryngeal dyspnea. Glottis localization was present in all our patients, i.e., 100% of the cases. A tracheotomy was performed in 9.67% of cases. All of our patients have had their papilloma peeled per endoscopic with tweezers. No cases of malignant degeneration were found in our study. CONCLUSION: Laryngeal papillomatosis is the most common benign tumor of the larynx in both children and adults. Despite the progress of endoscopy and antiviral treatments, its treatment poses many problems in our undermedicalized countries.

[Solitary neurofibroma of the maxillary sinus]. / Neurofibrome isolé du sinus maxillaire.

OBJECTIVE: To illustrate the rarity and difficulty diagnosing maxillary sinus neurofibroma through a case report. PATIENTS AND METHODS: A 35-year-old female consulted our department for left cheek swelling evolving over 6 months, upper gum swelling, and a dental occlusion disorder. RESULTS: A computed tomography scan showed a tumor of the left maxillary sinus with bone destruction. Histological examination of a biopsy fragment found an in situ carcinoma. A maxillary resection was performed to excise the tumor. Histological examination of the specimen showed a neurofibroma. No sign of recurrence was noted after 8 months of follow-up. CONCLUSION: The difficulty diagnosing maxillary sinus neurofibroma is related to its nonspecific clinical and radiological signs. Consequently, the otorhinolaryngologist must keep this rare histological variety in mind within the range of tumors of the paranasal sinuses.

Laryngeal papillomatosis in Senegal: A ten-year experience.

OBJECTIVES: The objectives of this study were to describe the epidemiological, clinical and therapeutic characteristics of laryngeal papillomatosis in the Fann teaching hospital ENT department in Dakar, Senegal. PATIENTS AND METHODS: We retrospectively reviewed all cases of laryngeal papillomatosis managed in the Fann teaching hospital ENT department between 1st January 2006 and 31st December 2015. Epidemiological, clinical and therapeutic characteristics of laryngeal papillomatosis were studied. Statistical analysis was performed with SPSS 18 software. RESULTS: The median age at diagnosis was 11 years and the sex ratio was 1.88. The mean time to consultation was 4.5 years. The predominant symptom was dysphonia, present in all cases, followed by laryngeal dyspnoea in 64.6% of cases. The glottic area was involved in all patients. Tracheostomy was performed in 20.8% of cases. All patients in our study underwent endoscopic excision of the lesions. CONCLUSION: Laryngeal papillomatosis is the most common benign tumor in children, but it can also occur in adults. Treatment has been revolutionized by progress in endoscopy and antiviral therapy. However, tracheostomy still occupies an important place in our practice.

A Rare Cause of Upper Airway Obstruction in a Child.

Ventricular band cyst is a rare condition in children but can result in severe upper airway obstruction with laryngeal dyspnea or death. The diagnosis should be considered in any stridor in children with previous history of intubation or respiratory infections. We report a case of a 4-year-old girl, received in an array of severe respiratory distress, emergency endoscopy was done, and a large ventricular tape band cyst obstructing the air way was found. Complete excision was made, and postoperative prophylaxis tracheotomy was done. The postoperative course was uneventful with improvement of clinical and endoscopic signs.

[Cranioencephalic complications of middle ear cholesteatoma: report of 4 cases]. / Complications infectieuses cranio-encephaliques de l'otite moyenne chronique cholesteatomateuse. A propos de 4 observations.

INTRODUCTION: Cranial and intracranial complications can be observed during middle ear cholesteatoma's evolution. We report our experience of management of infectious cholesteatoma's cranioencephalic complications. MATERIAL AND METHODS: In a three year period, we had consecutively admitted 4 patients with cranioencephalic complications of middle ear cholesteatoma, in the Ear Nose and Throat (ENT) department of the university teaching hospital of Dakar. After preoperative investigations with computed tomography scan (CT scan) of brain and temporal bone. The patients had been operated after paraclinic assessment. RESULTS: The finding showed one case of temporal bone otogenic extensive osteomyelitis with multifocal extradural empyema, 3 cases of brain abscess associated with subdural empyema and meningitis in 1 case. For 3 patients (75%), neurosurgical drainage and mastoidectomy were performed, associated with antibiotic treatment. The mastaidectomy was performed in the same time of the surgical procedure or delayed. One patient, with brain abscess, died before surgical intervention. With a follow up of 15 months, we have noticed stable mastoidectomies cavities and no neurological recurrence symptoms. CONCLUSION: These complications can be prevented by early treatment of chronic otitis media diseases. The appropriated management of these complications necessitate collaboration between otorhinolaryngologists and neuro surgeons.

[Hyperthyroidism surgery: experience of ENT department of hospital center of Thies]. / Chirurgie de l'hyperthyroidie: experience du service d'ORL du centre hospitalier regional de Thies.

INTRODUCTION: The treatment of hyperthyroidism includes different therapeutics means of which surgery. The objectives of this study were to evaluate the place of the surgery in the treatment of hyperthyroidism and to describes the complications. PATIENTS AND METHODS: It is a retrospective study on 22 patients treated by thyroidectomy from March 2002 to April 2004. The biological confirmation was systematic. A medical preparation has been done in all the cases. A total thyroidectomy has been done in 13 cases and a subtotal in 9 cases. RESULTS: The mean age was 37 years. There were 20 women and 2 men. An euthyroidism has obtained after surgery. There complications were: 1/22 temporary palsy of recurrent nerve 1/22 acute hypoparathyroidism 1/22 post-operative death (haematoma) CONCLUSION: Surgery seems to be a good alternative to antithyroid agents, which are constraining and often ineffective in the long term, and to radioactive iodine who leads to a long follow-up because of induced hypothyroidy. With increasing surgical skill, the risk of recurrent or parathyroid injury is greatly decreased.

[Head and neck paragangliomas in Senegal. About 8 cases]. / Paragangliomes de la tête et du cou au Sénégal.

UNLABELLED: Paragangliomas are uncommon neoplasms with rare occurrence in the head and neck area. OBJECTIVE: The purpose of this study was to report the experience of management of these rare tumors by a team of Ear, Nose, and Throat (ENT) surgeons working in the context of a sub-Saharan country. MATERIAL AND METHODS: We conducted a retrospective study in the Ear, Nose and throat Department of a Dakar university hospital. The study concerned 8 patients with a highly vascular tumor located in the neck and temporal bone. The preoperative investigations were computed tomography scanning (CT scan) using contrast injection in 88% and Doppler ultrasonography for the patients with a neck mass. All the patients underwent surgery except one. In 2 cases, the management with a team of vascular surgeons was necessary. Histological examination of the tumor was realized in all cases. RESULTS: The tumor was located in the neck in 5 cases (62,5%) with a carotid body tumor in three patients (37,5%) and vagal location in two (25%). The temporal bone was involved in three patients with a tympano-jugular location (37,5%). All the neck masses were operated on via a unique cervical approach. The tympano-jugular tumors were treated by radical mastoidectomy in two patients. In the third patient with a tympano-jugular tumor, with important involvement of the temporal bone, only the neck extension was operated. The histological diagnosis of paraganglioma was confirmed in all patients. Radiation therapy was delivered in two patients (25%), to complete surgery in the event of extensive temporal bone tumor and exclusive in one case of an inoperable vagal tumor. The outcomes, marked early death in one patient (14%), were good in the short and mid term for the others patients. CONCLUSION: With the improvement of technological infrastructures, particularly with developing modern imaging, we have better knowledge of paragangliomas in the head and neck area, in our experience in a developing country. However, therapeutic approaches are still limited by modest humans and material resources.

[Subdural empyema complicating acute frontal sinusitis. Four cases report]. / Empyème sous-dural compliquant une sinusite frontale aiguë. A propos de 4 cas.

OBJECTIVE: Subdural empyema is a collected cranioencephalic suppuration between arachnoid and dura meninge space. Subdural empyema occurring after sinusitis is an uncommon but serious complication of paranasal sinus infections. The purpose of this study is to aware the clinician about this condition. MATERIAL ET METHOD: Four young male children had been admitted with expressed fronto-ethmoid sinusitis. The intracranial infection was confirmed by computed tomography scan of brain and sinus. Both drainage of the sinus and intracranial suppuration was performed at the same time surgical procedure and antibiotics administered during 4 weeks. RESULTS: The subdural empyema was localized in the right temporoparietal region in 1 case, in the frontal lobe in the others cases. In 1 case, the frontal subdural empyema was associated with an inerhemispherique collection. One patient underwent a second drainage. Immediate post-operative outcomes were temporally complicated with convulsions and focal neurological deficit, in 1 case. This symptoms had regressed spontaneously. There was no case of death. The functional prognosis was bad, marked by lost vision in 2 cases, which was bilateral in 1 case. CONCLUSION: A high index of suspicion of intracranial extension of sinus infection must recommended neuroradiological investigations. When suppurative collection is confirmed, an appropriated management of the infection between otorhinolaryngologists and neurosurgeons is necessary.

[Pseudo-tumoral aspergillus rhinosinusitis: About two cases]. / Aspergillose sinusienne invasive pseudo tumorale: à propos de deux cas.

INTRODUCTION: Pseudo-tumoral fongal rhinosinusitis is a rare and benign illness due to saprophyte germ, Aspergillus flavus. OBSERVATION: We reported two cases of invasive pseudo-tumoral fongal rhinosinusitis. CT scan helped with diagnosis and allowed for extension assessment. Complete surgical excision was done through external approach. Bacteriological examination evidenced the germ. DISCUSSION: Pseudo-tumoral invasive fongal rhinosinusitis remains a potentially serious pathology because of its local aggressiveness and its multiple extensions.

[Laryngeal foreign bodies: management in children in Senegal]. / Corps étrangers laryngés: prise en charge chez l'enfant au Sénégal.

UNLABELLED: Inhalation of foreign bodies is a frequent accident in children. It remains severe in the case of laryngeal foreign bodies. PATIENTS AND METHODS: Retrospectively, for a 16-year period, 65 laryngeal foreign bodies have been treated (44.8%), among 145 cases of airway foreign bodies, in the ENT department of Dakar University hospital. Etiological, clinical and therapeutic aspects were reviewed. RESULTS: Average age was 36 months, with a sex-ratio of 2.42 in favour of males. The time lag (time between the accident and admission to the department) was particularly long; 73.33% of the children were admitted more than 24 hours after the event. Eighty-three percent of the patients presented greater or lesser laryngeal dyspnea. Tracheostomy was performed in 55.4% of the patients. Average duration for abiation of the canula was ten days. Three cases of death were recorded (4.16%). DISCUSSION: The frequency of 44.8% for laryngeal localization of foreign bodies appears to be the highest in the literature. If the appropriate treatment for foreign bodies in the respiratory tract is endoscopic removal, the tracheostomy nevertheless occupies a central place in the management of the disease. This procedure may be recommended to all ENT specialists working in similar conditions. In spite of its inherent complications, tracheostomy allows reduction of mortality in relation to laryngeal foreign bodies. Improvement of prognosis requires prevention based on widespread public information and improving technical infrastructures.

[Mucoceles of the maxillary sinus]. / Mucocéles du sinus maxillaire.

The term mucocele designates a cyst developing from a sinus mucosa, generally the frontal and/or ethmoidal sinuses. They present clinically as a benign tumor, and their diagnosis and treatment is usually simple. Maxillary sinus localizations are exceptional, however, and raise numerous problems in daily practice. Three cases of maxillary sinus mucoceles are reported.

[Limits to the practice of craniofacial oncology in Black Africa: the example of cancer of the larynx]. / Limites á l'exercice de la carcinologie cervico-faciale en Afrique Noire: l'exemple des cancers du larynx.

Cervico-facial carcinology is currently one of the major concerns of oto-rhino-laryngologists. The authors have chosen laryngeal cancers to determine the limits of the practice of such cervico-facial carcinology in the topics. Over a 10-year period, 61 patients with a suspected malignant laryngeal disease were examined at the E.N.T. Clinic of the University Hospital in Dakar. Histological confirmation was found in only 38 patients, and a curative treatment was undertaken with 27 patients. No significant differentiation could be found from the results as far as sex, age and histology were concerned. On the other hand, the TNM breakdown of our 36 carcinomas revealed that in 78% of the cases large tumours (T3, T4) were involved. In the vast majority of these cases (18/27), treatment was purely surgical, with a total laryngectomy in 90% of the cases. Pharyngostomas accounted for the majority of the early postoperative complications (6/14). Over 10 years of practice, 70% of our patients have died or have been lost from sight. These poor results are due to numerous factors, including late consultation, the lack of specialists and the insufficiency of technical facilities. To improve results, the authors recommended the setting-up of proper cancer institutes.

[Neck trauma in civil practice: a 16-year experience]. / Les traumatismes du cou en pratique civile: une expérience de 16 ans.

In spite of their seriousness, neck traumatism still are an unknown pathology. In a 16 years old hospital practice we have recorded 27 cases of neck traumatism. They concern, mainly, male adult. Accidental circumstances deal only with civil practice. The vulnerant agent is white weapon in 63% of the cases either in a suicide or aggression purpose. Because it occurs, mainly, with white weapons, penetrating wounds are more frequent (85%). Exploration cervicotomy has been indicated for 23 patients. But it was effective for only 22 patients. In 83% of cases surgery occurred in the first 48 hours delay. It permitted to find out a 78% score of aero-digestive tracks, and about 22% of vascular injury. We have recorded two death cases. One of them was noticed after surgery. These 27 cases do not, indeed, reflect the reality. Many people who died immediately after their accident may have undergone unseen neck traumatisms. By the same way, numbers of "closed" internal neck traumatisms have been misknown in the hospital. We, thus, suggest a reorganisation of surgical and medical emergencies in Senegal.

[Cylindroma of the epiglottis]. / Cylindrome de l'épiglotte.

The observation of an exceptional laryngeal localization of an adenoid cystic carcinoma allows authors to review diagnostic, therapeutic and increasing problems of this glandular carcinoma. The reported case constitutes a histologic surprise. An economical removal has allowed to obtain a long remission without recurrence, nor metastasis; this never put back the principle of the broad surgery to institute when faced this type of cancer, but just emphasize the interest of an early treatment.

[Problems with carotid chemodectomas]. / Problèmes des chémodectomes carotidiens.

The authors report on their initial observation of a Shamblin Type I carotid body chemodectoma. Surgical exeresis was complete and relatively easy even though the diagnosis has been carried out in the open air. They take the opportunity to discuss diagnostic, therapeutic, evolutional and nosological problems connected with this rare neoplasm.

[Partial laryngectomies at the University Hospital Center of Dakar]. / Laryngectomies partielles au Centre Hospitalier Universitaire de Dakar.

Our experience on partial laryngectomies stretched on a period of 16 years. In an unfavorable medical environment, we issue our indicative criteria throughout this experience. From January 1st 1981 to December, 31st 1996, 14 patients have had a partial laryngectomy in University Hospital Center of Dakar. The average year was 56 and the sex-ratio was 1 woman out of 13 men. There were 13 carcinomas and 1 cas of acute dysplasia. 4 patients have had vertical partial laryngectomy, 5 have had a horizontal partial laryngectomy and 5 a partial laryngectomy on the upper out of the cricoid cartilage with the ganglia. After a 3 years close look, on 10 patients, we noted that 1 died, 1 disappeared, and 8 still were living. Carcinological failures consisted in 3 development by stages and 1 cas of a 2nd localisation. As for as functional results, the removal of the nozzle and the elimination of the nasogastric grohe of supply, were effective for respective average allotted time of 11 and 12 days. This laryngeal partial surgery seem scarce in our practice (12% of the patient who have had it). The improvement of results go to the choice of indications, the information the formation and the acquisition of technical stools more efficient.

[Tracheotomy in the child with a foreign body in the lower respiratory passages]. / Trachéotomie chez l'enfant porteur d'un corps étranger (CE) des voies respiratoires inférieures (VRI).

In 15 years period, 137 children with foreign bodies of inferior respiratory tracts were admitted in the otorhinolaryngology and head and neck department of the University of Dakar. For 48 of them, generally late admitted, a tracheostomy was performed. Male children were most affected. About 81% of the removed foreign bodies were organic, dominated by peanuts. 76% of the foreign bodies were found in the larynx. Tracheostomy had been realized before extraction of foreign body for 90% of the cases and after extraction for the others 10%. One case of death was to be deplored. This critical place of tracheostomy increases the morbidity and the mortality in relation with the inhalation of foreign body. This unusual practice of tracheostomy illustrates the arduousness of our working conditions.

[Diagnosis and treatment of thyroglossal cysts and fistulae (Sistrunck or Schlange?): reflections on 40 cases]. / Diagnostic et traitement des kystes et fistules thyréoglosses (Sistrunck ou Schlange?): réflexions à propos de 40 cas.

40 cases of cysts and fistulas of the thyroglossal tract duct offer to the authors occasion to review the rare problems of diagnosis raised by this pediatric pathology. They compare the results of surgery obtained by the classic technic of Sistrunck (1920) versus the Schlange's operation (1893) which remove the cyst with the hyoid bone's body only. The average of age is 17 years. A location of a thyroglossal cyst in the submandibular area was noted during operation. Sistrunck's operation was performed in 21 cases (52.5%) and the Schlange's one in 14 cases (35%) without recurrence. 4 cases (10%) recurrences were noted, all after simple cystectomy. Removal of the hyoid bone's body appear to us as the key of success in the surgery of thyroglossal anomalies.

[Lethal midline granuloma in Senegal. (Apropos of 15 cases)]. / Le granulome médio-facial au Sénégal (A propos de 15 observations).

African authors, other than senegalese, have not paid enough attention to lethal granuloma, a terrible disease. This series is about a series collected between 1975 and 1990. It is particularly high compared to other series in the world. If diagnosis is easy for the clinician, much care must surround the pathological answer. Those diagnosis problems and difficulties of treatment (represented by 11 deaths) are studied.
