Secondary insertion of Provox®2 using an endotracheal tube

Abstract

Conclusion: A procedure with no exploratory puncture using an endotracheal tube, sharp-tipped trocar, flexible fiberscope, and flexible guidewire is useful for inserting the Provox®2 prosthesis. Objectives: The purpose of the present study was to examine the necessity of exploratory puncture in consideration of operating time, complications, and voice rehabilitation. Methods: Insertion of the Provox®2 was conducted using an endotracheal tube, sharp-tipped trocar, flexible fiberscope, and flexible guidewire under general anesthesia. This was performed in conjunction with exploratory puncture in the first 7 patients, and without exploratory puncture in the following 15 patients. Results: Operating time was 10 min in the group with exploratory puncture and 6 min in the group without exploratory puncture. Although a shorter size had to be substituted in one patient without exploratory puncture on the day following the procedure due to difficulty with eating, no complications due to the procedure were observed in any patients. Speech production was possible in all patients on the following day.
