Phonatory and Radiological Analysis in Modified Montgomery Thyroplasty.

Area of Science:

• Otolaryngology
• Voice Science
• Medical Imaging

Background:

• Assessing phonatory and radiological features post-modified Montgomery thyroplasty.
• Evaluating hoarseness, roughness, and breathiness (GRB) using Auditory Perceptual Voice Evaluation Scale.
• Investigating functional voice characteristics and sex-based differences.

Purpose of the Study:

• Analyze phonatory and radiological characteristics in patients with optimal vs. suboptimal GRB scores.
• Determine the influence of sex on voice quality and functional parameters.
• Correlate functional outcomes with laryngeal imaging findings.

Main Methods:

• Descriptive study of postoperative phonatory results.
• Radiological analysis using laryngeal computed tomography (CT) scans.
• Measurement of nine key laryngeal landmarks on CT images.

Main Results:

• Younger patients generally achieved better outcomes.
• Optimal GRB group showed significantly greater Voice Handicap Index-30 (VHI-30) improvement.
• No significant differences in maximum phonatory time (MPT) between groups; sex influenced MPT and radiological findings.

Conclusions:

• A significant relationship exists between optimal hoarseness grade and VHI-30 score.
• Maximum phonatory time (MPT) was not significantly related to GRB grade or VHI-30.
• Laryngeal radiological data, specifically thyroid window location, were described in relation to surgical outcomes.
