Abstract

Laryngeal mucosal perforation is a frequent event whose diagnosis is based on clinical, laryngoscopic and CT findings.

Nineteen patients with small skin tears and no signs and symptoms of laryngeal injury were immediately discharged while 37 patients were submitted to surgery: 17 to remove cerebral hematomas, 13 to stabilize cervical fractures and 7 because of hemodynamic instability. Twenty-one patients underwent laryngoscopy which showed laryngeal lesions in 12: wide mucosal disruption with fractures of the laryngeal skeleton and hematomas were observed, which needed immediate surgery with airway reconstruction in 7 cases; small mucosal tears and hematomas were seen and laryngeal CT examination was requested to establish the possibility of conservative management in 5 cases which are the subject of the present study. Laryngoscopic findings were: 1) laryngeal mucosal tear near the thyroid cartilage with quadrangular membrane edema, 2) thyroid mucosal tear with thyrohyoid muscle ...Continue Reading
