ABSTRACT
Objective: To investigate by means of videostoboscopy the characteristics of the neoglottis after total laryngectomy with primary or secondary voice reconstruction using a non-prosthetic tracheoesophageal fistula technique. Methods: Design: Cross-Sectional Study Setting: Tertiary Public Hospital Subjects: Twenty alaryngeal patients Results: Videostroboscopy enabled evaluation of the neoglottis in all but two patients with a pectoralis major myocutaneous flap reconstruction of the pharyngoesophageal segment. Pooling of saliva was present in the cranial neoglottic opening in all subjects, but obscured visualization in these two. A circular neoglottic shape was most commonly seen. Vibration of the neoglottis was noted in 90% of all alaryngeal patients and was associated with a regular mucosal wave. Pharyngoesophageal vibration was noted in two thirds of patients. It was associated with a strong mucosal wave, regular vibration and a longer open phase. Conclusion: Videostroboscopy confirmed that neoglottic vibration accompanies sound production while pharyngoesophageal vibration may reinforce and enhance voice production in alaryngeal patients with non-prosthetic TE voice reconstruction.
