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

Area of Science:

• Otolaryngology
• Speech and Voice Science

Background:

• True vocal cord paralysis impairs the larynx's ability to produce sound.
• Medialization laryngoplasty is a key surgical repair technique.
• Alternative methods like the Mini-Window technique are being explored.

Purpose of the Study:

• To compare the effectiveness of the Mini-Window technique versus classic medialization laryngoplasty for vocal cord paralysis.
• To evaluate voice parameters and surgical outcomes.

Main Methods:

• A study involving 30 participants with unilateral vocal cord paralysis.
• Random assignment of 15 participants to either classic medialization laryngoplasty or the Mini-Window technique.
• Pre- and post-operative evaluation of voice parameters (pitch, jitter, shimmer, hoarseness) and surgical duration.

Main Results:

• The Mini-Window method demonstrated significant improvements in voice quality, notably reducing voice shimmer.
• Surgical duration was also significantly shorter with the Mini-Window technique.
• Both techniques showed effectiveness in treating vocal cord paralysis.

Conclusions:

• The Mini-Window technique is an effective alternative for treating vocal cord paralysis.
• This method provides a more efficient surgical procedure with enhanced voice quality, specifically reduced shimmer.
