Closed External Trauma of the Larynx: About Four Cases Collected in Bamako

Objective: The purpose of our work was to review through four observations the mechanisms of injury, the main signs calling for classification in the management of blunt external trauma to the larynx in a hospital of last resort in Mali. Observations: We reported a series of four cases of blunt external trauma to the larynx, all of which occurred in the context of a public road accident (AVP) with reception of the shock at the level of the anterior part of the neck. Dysphonia was the most constant sign, it was associated with dyspnea. All our patients had benefited from a Nasofibroscopy or a direct laryngoscopy and a pharyngolaryngeal computed tomography allowing them to be classified according to the classification of Schaefer and Fuhmann. A patient with arytenoid dislocation underwent endoscopic reduction. Exploratory cervicotomy was performed in one patient. Conclusion: Adequate management of external trauma to the larynx requires a structured, rapid and precise diagnostic and therapeutic approach. This constitutes a challenge in our context where the mobilization of the patient and the diagnostic means (nasofibroscopy or a direct laryngoscopy, pharyngolaryngeal computed tomography) in the absence of third-party payment are part of a course of overcoming obstacles.
