Videostroboscopic Evaluation of Neoglottis in Alaryngeal Patients after Tracheoesophageal Voice Reconstruction without Prosthesis

Jeanne O. Madrid | Celso V. Ureta

 

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.
