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.

Schwannome endonasal à localisation turbinale inférieure. A propos d'un cas

Introduction : Le schwannome est une tumeur bénigne développée aux dépens des cellules de Schwann des nerfs périphériques. La localisation endonasale en particulier au niveau des cornets est rare. Observation : Nous rapportons le cas d'une femme de 23 ans reçue dans notre structure pour une masse de la fosse nasale droite localisée au niveau du cornet inférieur, obstruant totalement la lumière nasale, sans envahissement local. Après un bilan endoscopique et radiologique, l'exérèse a été effectuée par voie endoscopique endonasale. L'analyse de la pièce opératoire avait mis en évidence un schwannome. Avec un recul de 24 mois nous n'avons pas noté de récidive. Conclusion : Le schwannome à point de départ turbinal inférieur constitue une entité rare. Il doit être considéré dans le diagnostic différentiel d'une tumeur bénigne unilatérale des cavités naso-sinusiennes

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.

Manejo quirúrgico de los carcinomas diferenciados de tiroides Experiencia en un país de bajos ingresos / SURGICAL MANAGEMENT OF DIFFERENTIATED THYROID CARCINOMAS. EXPERIENCE IN A LOW INCOME COUNTRY

ience in the management of differentiated thyroid carcinomas in a low- income country. Materials and Methods: We performed a retrospective study in our department where 21 cases of differentiated thyroid carcinomas were recorded from February 2001 to December 2010. Results: We performed 334 thyroidectomies for 326 patients. Of this group, 21 differentiated thyroid carcinomas were diagnosed. Differentiated thyroid carcinomas represented 6.4% of all thyroid neoplasm managed during the same period (n=326). Median age was 44 years (range 13 - 75 years). Male to female ratio was 1:20. Six (6) patients underwent primary hemithyroidectomy in other institutions while the fifteen left were entirely managed in our clinic. Of them, one patient was referred with positive fine needle aspiration cytology for papillary thyroid carcinoma (incidental detection by fine needle aspiration biopsy) and another had history of sinus pyriform fistula. Pathology of surgical specimens showed 13 cases of papillary thyroid carcinomas and 8 cases of follicular thyroid carcinomas with association to Hashimoto thyroiditis and Grave's disease in respectively in 1 case. Twenty cases were incidentally discovered by thyroid surgery and undergone completion thyroidectomy with prophylactic central neck dissection, completion thyroidectomy alone, modified lateral neck dissection alone and surveillance respectively in 13, 1, 1 and 6 cases. Complications of thyroid surgery were bilateral recurrent laryngeal nerve paralysis and hematoma respectively in 1 case. Median hospital stay was 5 days ranged from 3 to 15 days. During the follow-up period, most of our patients were lost of follow-up. Conclusion: Management guidelines of differentiated thyroid carcinomas are well established but not applicable to low- income country for several reasons. National guidelines, based on further researches, must then be implemented to improve 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.

Kyste valléculaire symptomatique de l'adulte. A propos d'un cas

Les kystes valléculaires encore appelés kystes épiglottiques ou kystes basi-linguaux sont des kystes canalaires qui traduisent l'obstruction et la rétention de mucus au niveau des canaux excréteurs, des glandes sous-muqueuses. Ils peuvent se manifester chez le nouveau-né par une détresse respiratoire aiguë, chez l'adulte ils sont le plus souvent asymptomatiques et sont découverts lors d'une laryngoscopie indirecte ou lors d'une intubation.L'objectif de ce travail était de rapporter un cas de kyste valléculaire symptomatique chez un adulte de 50 ans pris en charge au service d'ORL et de chirurgie cervico-faciale de Hôpital Général de Grand Yoff, Dakar, Sénégal. La nasofibroscopie a objectivé une formation kystique arrondie siégeant au niveau de la vallécule gauche. La tomodensitométrie cervico-faciale a mis en évidence une masse valléculaire gauche hypodense homogène plaquant l'épiglotte contre le plan glottique. Au plan thérapeutique, nous avions effectué une ponction première du kyste suivie de son exérèse complète par électrocoagulation de la base d'implantation. Les suites opératoires étaient simples

Paralysie récurrentielle bilatérale : l'aryténoïdopexie est-elle toujours compétitive ?

Introduction : La Paralysie Récurrentielle (PR) bilatérale en adduction est une situation clinique dramatique. Le traitement repose sur la chirurgie par voie endoscopique couplée au laser. Ce procédé thérapeutique est inaccessible dans beaucoup de pays en développement. La chirurgie par voie externe peut-elle constituer une alternative ? Matériel et méthodes : Nous avons mené une étude rétrospective portant sur 20 patients, porteurs d'une PR bilatérale en adduction post-thyroïdectomie, sur une période de 12 ans. Tous les malades ont été traités par abord chirurgical cervical externe. L'appréciation des résultats se faisait sur la possibilité de décanulation et la qualité de la voix.Résultats : Tous les malades étaient de sexe féminin avec un âge moyen de 43 ans. La PR était une complication de la thyroïdectomie totale dans 85% des cas et subtotale dans 15% des cas. L'abord latéral du larynx nous a permis de réaliser 16 aryténoïdopexies selon King et 2 aryténoïdectomies associées à une cordopexie selon Graaf Woodman. L'abord antérieur par thyrotomie, effectué dans 4 cas, a permis de réaliser une aryténoïdectomie dans 1 cas et une cordo-aryténoïdectomie dans 3 cas. La décanulation a été effective chez tous les malades après un délai moyen de 30 jours. Après analyse perceptuelle, chez 11 patients, la qualité de la voix était jugée bonne dans 4cas (36.63%), passable dans 2 (18.18%) et mauvaise dans 5 (45.46%).Conclusion : Nos résultats sont satisfaisants et comparables à ceux des séries des pays développés, usant des procédés endoscopiques au laser

Corps étrangers laryngo-trachéo-bronchiques : à propos de 130 cas

Objectifs : Les objectifs de notre étude étaient de décrire les aspects épidémiologiques, diagnostiques et thérapeutiques des corps étrangers des voies respiratoires inférieures à la clinique d'ORL et de chirurgie cervico-faciale du centre Hospitalier National et Universitaire de Fann. Patients et méthodes : Il s'agit d'une étude rétrospective, couvrant la période du 1er janvier 2011 au 31 décembre 2013. Nous avons colligé, durant cette période, 130 dossiers de patients âgés de moins de 18 ans qui étaient reçus pour inhalation de corps étrangers. Les endoscopies blanches étaient exclues. Les paramètres étudiés étaient : l'âge, le sexe, la présence ou non d'un syndrome de pénétration, les signes fonctionnels, le délai de consultation, le traitement effectué, la localisation endoscopique, la nature du corps étranger, les données de l'imagerie, l'indication de la trachéotomie et les complications. L'analyse des données était effectuée avec le logiciel Sphinx Lexica V 4.5 2003. Résultats : L'âge moyen de nos patients était de 3,84 ans avec des extrêmes allant de 4 mois à 17 ans. Une prédominance féminine était notée avec un sex-ratio de 0,91. Les patients évacués d'autres pays représen- taient 6,9% des cas. Le délai moyen de consultation était de 8,05 jours. Le syndrome de pénétration était retrouvé dans 78,5% des cas. La radiographie standard mettait en évidence un corps étranger radio-opaque dans 33,1% des cas. La localisation laryngée était la plus fréquente, elle représentait 26,7% des cas. La graine d'arachide était le corps étranger le plus fréquemment retrouvé soit 39,2%. Onze patients étaient trachéotomisés. Quatre cas de décès ont été rapportés soit 3% des cas.Conclusion : L'inhalation d'un corps étranger est un problème de santé publique. L'augmentation de l'incidence de cet accident et la transition épidémiologique impose une meilleure prévention

[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.

[Primitive neuroectodermal tumor of the vagus nerve]. / Tumeur neuroectodermique primitive du nerf vague.

Primitive neuroectodermal tumors are a rare type of malignant neuroectodermal tumor that is very aggressive. Cervicofacial location is rare, even exceptional. We report a case of a 4-month-old male infant, referred from the pediatric clinic for severe supralaryngeal dyspnea, a firm mass under the left mandibular angle, mobile and extended to the parotid area, painful, with a curve of the left side wall of the oropharynx. Cervical computed tomodensitometry showed a well-limited mass in the carotid area, enhanced by the contrast product. A vascularized mass, which had developed at the expense of the vagus nerve, was removed surgically. Histology found a primitive neuroectodermal tumor.

Management of acquired cholesteatoma in children: a 15 year review in ENT service of CHNU de FANN Dakar.

OBJECTIVES: To analyze the epidemiology, diagnosis, management and the prognosis of cholesteatoma of the middle ear in children. METHODS: This was a retrospective study of 15 years (from 01 January 1995 to 31 December 2009) for patients aged 0-15 years admitted in ENT ward of FANN hospital for chronic otitis media complicated with cholesteatoma The parameters studied were epidemiology, clinical presentation, disease progression and management. RESULTS: Sixty-six participants were included. We noted a slight male predominance with a sex ratio of 1.44. The average mean age was 10 years. Most patients presented with signs of complications (69.7%) and mastoiditis was the most common complication (63.6%). The otorrhea was noted in almost all patients: n = 64 (97%) and deafness in 49 patients (74, 2%). There was a slight predominance of cholesteatoma on the right side (51.5%). Schuller's view of the mastoid cells was done in 21.2% of patients (n = 14) and showed sclerotic mastoid air cells for all them. Eighty-two percent (82%) of patients presented with conductive hearing loss. A radical mastoidectomy was performed in 66.7% and modified radical mastoidectomy in 33.3% of cases. Mean follow-up was 6 months. Recurrence of cholesteatoma was noted in 13% of cases. CONCLUSIONS: ENT ward of Hospital Fann is one of the two centers in Senegal where cholesteatoma of the middle ear are treated. This low number of cholesteatoma in children in a developing country is in relation to the fact that patients only present when complications develop: 70% of cases. The reason for this in our setting include insufficient human and manpower resources necessary for prompt management of the disease and also lack of awareness among the populace. In these settings we advocate canal wall down mastoidectomy (radical or modified radical) as the treatment of choice.

A case of cervical Pott's disease revealed by parapharyngeal abscess.

INTRODUCTION: We report a case of cervical Pott's disease revealed by parapharyngeal abscess. CASE REPORT: A seven-year-old boy was admitted with a three-week history of painful fluctuating left lateral cervical swelling, associated with night sweats. Examination found trismus, through which a lateral pharyngeal bulge could be observed. Incision and drainage of the abscess on a combined cervical-oropharyngeal approach was performed under general anesthesia, associated to non-specific antibiotherapy by parenteral route. Bacteriology was negative. After one week of antibiotherapy, fever persisted with onset of torticollis. A diagnosis of tuberculosis was considered. Tuberculin skin test was positive at 16.5 mm. A second sample by pharyngeal aspiration showed caseous pus with acid-fast bacilli. Cervical spine CT found a retrostyloid abscess with atlantoaxial lysis. Cervical Pott's disease complicated by Grisel syndrome was diagnosed. Antituberculosis therapy was initiated. Results at five months' follow-up were satisfactory. DISCUSSION/CONCLUSION: Parapharyngeal abscess with an etiology of Pott's disease is rare. Modern imaging is highly contributive to diagnosis and follow-up of lesion regression under treatment.

Osteolipoma: an unusual tumor of the parotid region.

PURPOSE OF STUDY: Oncology of the parotid region is rich and varied, like its components. During his career, the ENT surgeon may come across such an exceptional tumor as osteolipoma. The aim of this study was to describe the rarity and the etiopathogeny of osteolipoma with parapharyngeal location. PATIENTS AND METHOD: We had the opportunity to find this uncommon tumor in a 21-year-old female patient. The mass located in the parotid region was hard, barely mobile and at first looked like a parotid tumor. Total parotidectomy with facial nerve preservation was performed. It revealed a stony and dented tumor inside the internal lobe of the parotid located in the parapharyngeal space between the vertical portion of the mandible anteriorly and the styloid apophyse posteriorly. Macroscopic examination of the piece evidenced a lipomatous mass with hard as bone nodes in its middle. Histology revealed an osteolipoma. CONCLUSION: A review of the literature shows the uncommon occurrence of this type of tumor. A few rare cases were reported among which two involving the parapharyngeal space.

[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.

[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.

Squamous carcinoma of the hypopharynx in children in Sénégal: between disarray and enigma.

INTRODUCTION: The squamous carcinoma of the hypopharynx constitutes the first reason of hospitalization in our department. Different studies have been realized about it and showed an epidemiological profile characterized by the young age of the patients and the predominance of female. OBJECTIVES: To specify the place of the children in hypopharynx cancers. To evaluate the epidemiological criteria and the difficulties in the management. MATERIALS AND METHODS: Retrospective study of 11 years (1995-2005). Collection of the data concerning the epidemiology, clinical and paraclinical findings, the treatment, and the evolution was carried out at the University Department of Otorhinolaryngology in Dakar (Sénégal). RESULTS: 15 charts of children have been collected. They presented in the majority of the cases, an advanced cancer, with 93% of T3T4. The lesion was localized at the retro-cricoid area in 4 cases, the pyriform sinus in 3 cases, the oesophagus junction in 2 cases, and the posterior wall in 1 case. In 5 cases the lesion was spreading to the totality of the hypopharynx. No case of smoking or alcohol has been noted. The anemia has been noted in 86.7% of the cases. A case of papillomatosis of the mouth and lips has been noted. The treatment was for most of cases as symptomatic, like tracheotomy with or without gastrostomy. The evolution was fatal with 11 deaths (73.33%). DISCUSSION: Our set is the richest set through the world of hypopharyngeal cancers in children. The Plummer-Vinson syndrome noted in 86.7% of the cases and the viral infection by HPV could play a role in the genesis of this cancer. CONCLUSION: The cancer of the hypopharynx essentially affects the young women in Sénégal without alcohol or tobacco consumption. It does not save the children, with an awful prognosis, however. So, it is imperative to organize a vast campaign of information of the populations on the bad prognosis of this cancer and to lead a large-scale epidemiological investigation, to get a better understanding of this cancer in our country.

[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.

[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.
