Les lymphangiomes kystiques sont des lésions congénitales bénignes prédominantes nettement au niveau de la région de la tête et du cou plus particulièrement dans le triangle cervical postérieur. Ces malformations des vaisseaux lymphatiques sont fréquemment diagnostiquées chez l'enfant. Nous rapportons le cas clinique d'un lymphangiome kystique du plancher buccal ayant survenu chez un adulte de 28 ans et qui s'est étendu progressivement vers la région sous mandibulaire gauche. La tumeur suspecté cliniquement a été bien exploré à la tomodensitométrie. Le traitement a consisté en une exérèse complète par voie endobuccale avec étude histologique qui a confirmé le diagnostic d'un lymphangiome kystique macroscopique. Le suivi à quatre ans n'a montré aucune récidive.

Il s'agit d'une étude prospective et descriptive portant sur les patients admis en consultation d'oto-rhino-laryngologie, au sein de l'hôpital marocain médico-chirurgical de campagne, déployé en Guinée Conakry, du 24 février au 24 mai 2014. Les critères d'inclusion étaient l’âge, le sexe, le type et la localisation de l'affection. L'objectif de notre étude est d’établir un regroupement diagnostique et topographique des principales affections otorhinolaryngologiques rencontrées en Guinée Conakry. Ont été examinés 1877 patients, soit une incidence de 8,14% si l'on rapporte au nombre total de la consultation pluridisciplinaire. La série comprenait 56,04% de femmes (n =1052) et 43,96% d'hommes (n = 825). L’âge de nos patients variait de 9 mois à 73 ans avec une moyenne de 33 ans, la tranche d’âge la plus touchée était celle de 20 ans à 29 ans et 53,54% des patients avaient un âge compris entre 20 ans et 39 ans. Au plan diagnostique, la pathologie infectieuse était la plus fréquente (54,51%), suivie de la pathologie ototologique non infectieuse et non tumorale entrainant surdité ou acouphènes (18,96%), de la pathologie inflammatoire rhino-sinusienne et pharyngée (18,01%), de la pathologie tumorale (6,34%), des corps étrangers de la sphère ORL (0,69%), des chéloïdes (0,43%) et de la pathologie malformative (0,37%). Au plan topographique, les affections rhino-sinusiennes étaient les plus fréquentes (37,93%), suivies des affections otologiques (33,46%), des affections oro-pharyngées et laryngées (21,20%) et des affections cervicales (6,34%).

Head and neck myxofibrosarcoma is rare. MRI is essential and should always precede treatment. Diagnosis is histological. There is elevated risk of local recurrence after resection, accompanied by worsening tumor grade, whence the need for accurate diagnosis, appropriate treatment and regular MRI follow-up.

The Castleman disease (CD) is a rare disease of unknown etiology, characterized histologically by angiofollicular lymphoid hyperplasia. It comes in two forms, unicentric and multicentric. We report a case of Castleman disease in a 58 year old man, who had consulted for chronic cervical lymphadenopathy. This case was a multicenteric and rapidly fatal despite aggressive treatment with corticosteroids, and chemotherapy

<p class="abstract">Laryngeal fracture is a rare and potentially fatal traumatic injury. Because of the rarity of this type of injury, many laryngeal fractures are often undiagnosed or poorly managed, leading to significant problems with airway patency, voice production, and swallowing. We report a case of a 49 year old man admitted to the emergency room after a motor cycle accident with cervical trauma. The patient presented with hoarseness, anterior neck pain, cervical subcutaneous emphysema, and increasing respiratory distress that led to the tracheostomy of the patient. The computed tomography (CT) of the neck revealed a comminuted fracture of the thyroid cartilage, a hematoma of the left piriform sinus and cervical subcutaneous emphysema. The three-dimensional CT showed a double fracture of thyroid cartilage with displaced intermediate fragment. The patient underwent an open reduction and internal fixation of the thyroid cartilage with miniplates along with laryngeal stenting. He has no significant swallowing or breathing problem and reasonably good voice 6 months after surgery. We conclude that early diagnosis and appropriate therapy favorably alters the prognosis in terms of long-term voice and airway outcome.</p>

Peripheral facial nerve palsy (FNP) is the most common cranial nerves neuropathy. It is very rare during dental treatment. Classically, it begins immediately after the injection of local anaesthetic into the region of inferior dental foramen and it's homolateral to the injection. Recovery takes a few hours, normally as long the anaesthetic lasts. The authors present a 44-year-old patient who presented a contralateral delayed-onset facial paralysis arising from dental procedure and discuss the plausible pathogenesis mechanism of happen and a possible relationship between dental procedure and contralateral FNP.

Parotid tuberculosis remains a very rare localization in the Department of Otolaryngology and Cervico-Facial Surgery (ENT) sphere. It is presented in the form of a deceptive clinical picture causing confusion with other pathologies of the parotid gland, including tumor pathology. In addition, its lack of knowledge by practitioners increases the risk of missing the diagnosis. Often, the diagnosis is a histological surprise on a piece of excision after an exploratory parotidectomy. However, its treatment is primarily medical if the positive diagnosis is well established. We report medical observation of two new cases aged 44 and 45 respectively, who consult our center for parotid swelling. Radiological examinations were in favor of intraparotid cystic lesions. Both patients benefited from an excision whose histopathological study was in favor of primary parotid tuberculosis. The subsequent evolution was favorable under antituberculous treatment.
