# Classical vs. New Mini-Window Medialization Laryngoplasty Method in Glottic Insufficiency

## TL;DR

This study compares two surgical techniques for vocal cord repair, finding that the Mini-Window method improves voice quality and reduces surgery time.

## Contribution

The study introduces the Mini-Window medialization laryngoplasty as a more efficient alternative to classic methods.

## Key findings

- The Mini-Window method significantly reduced voice shimmer compared to the classic technique.
- Surgery duration was shorter with the Mini-Window approach.
- Both methods improved voice parameters, but Mini-Window was more efficient.

## Abstract

True vocal cord failure (glottis) refers to the inability or failure of the larynx structure and vocal cords to produce sound. One of the optimal techniques for repairing this lesion is medialization laryngoplasty, which restores sound strength, continuity, and quality. Another technique is to create a Mini window in the periphery of false vocal cords. This study compared the effectiveness of medialization laryngoplasty with Gore-tex in two classic medialization laryngoplasty techniques and the Mini window method in the periphery of false vocal cords.

A total of 30 participants who had unilateral vocal cord paralysis due to various causes, such as surgery, metastasis, and intubation, were studied. After obtaining informed consent from patients, 15 participants were assigned to each group (classic or mini-window medialization laryngoplasty). Voice parameters, such as pitch, jitter, shimmer, and hoarseness, were evaluated before and after surgery. The duration of the surgery was also compared.

The Mini-Window method significantly improved sound quality, resulting in lower voice shimmer and shorter surgery duration.

While both methods are effective, the Mini-Window technique offers a more efficient surgery with reduced voice shimmer.
