Obstructive sleep apnea syndrome after reconstructive laryngectomy for glottic carcinoma

Obstructive sleep apnea syndrome (OSAS) is characterized by repetitive episodes of partial or complete obstruction of the upper airway during sleep. The obstruction predominantly occurs along the pharyngeal airway but other sites of obstruction have occasionally been described. We report our experience with three patients suffering from OSAS suspected to be of laryngeal origin. OSAS developed after reconstructive laryngectomy for glottic carcinoma and upper airway obstruction seemed to be located in the reconstructed laryngeal area. The three patients were given nCPAP (nasal-continuous positive airway pressure) treatment associated with peroral endoscopic CO2 laser vaporization of the laryngeal edema. After CO2 laser treatment, one patient was able to stop nCPAP treatment. The other two have remained on nCPAP therapy. OSAS may arise in the post-operative period of reconstructive laryngectomy for glottic carcinoma and can be managed by CO2 laser vaporization (laryngeal edema in the reconstructed area) in association with nCPAP treatment.
