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%).

<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>

Background Antrochoanal or Killian polyp is a rare polyp of the maxillary sinus in adults. It is generally unilateral, implanted on the lateral wall of the maxillary sinus upon the uncinate process. Bilateral cases are very rare; only 14 cases have been cited from 1980 to 2020. Case presentation Our patient presented with a complete bilateral nasal obstruction, this symptom persisted for more than 10 years, with a perceived prolapse in his throat in the last 4 months. Anterior rhinoscopy showed a polyp that took up the totality of his nasal vestibule. Posterior rhinoscopy showed a polyp bulging behind the uvula. The challenge in this case is related to diagnosis decision; conditions with the same clinical presentation are several. Diagnosis was established through the clinical, radiological, and endoscopic aspects, and confirmed by histological findings. Management was obtained through functional endoscopic sinus surgery; no recurrence was noted in the 12-month follow-up, and clinical signs had completely subsided. Conclusion Diagnosis in bilateral forms of Killian polyp is perplexing; however, its management is generally simple, with excellent outcome. We report the case of the 15th patient along with a systematic literature review discussing bilateral Killian polyps, illustrated by a rare case of enormous bilateral antrochoanal polyps.
