# Voice quality after open partial horizontal laryngectomy vs. total laryngectomy with voice prosthesis: a comparative study

## TL;DR

This study compares voice quality outcomes after two types of laryngeal surgeries, finding that total laryngectomy with a voice prosthesis may offer slightly better voice quality.

## Contribution

The study provides a direct comparison of voice outcomes between open partial horizontal laryngectomy and total laryngectomy with a voice prosthesis.

## Key findings

- Voice quality was slightly better in total laryngectomy patients using a voice prosthesis.
- Scores in I-SECEL and acoustic analysis were comparable between the two groups.
- The study enrolled 43 patients for voice outcome assessment.

## Abstract

The aim of this study is to compare voice outcomes in open partial horizontal laryngectomy vs. total laryngectomy (TL) with voice prosthesis.

In this retrospective monocentric study patients undergoing OPHL or TL with voice prosthesis were enrolled during the usual oncological follow-up consultations at the Otolaryngology and Audiology Unit of a University Hospital in the period between July 2022 and June 2023. Acoustic analysis (F0, HNR, NHR), maximum phonation time, I-SECEL and INFV0 scale were used to assess voice outcome.

Forty-three patients were enrolled. Voices of patients undergoing LT were better in quality of voice (V0) at INFV0 scale. The scores in I-SECEL and acoustic analysis were comparable.

Voice quality could be slight better in patients undergoing TL with voice prosthesis than those undergoing OPHL.
