Summary
Carbon dioxide laser surgery effectively restores voice in patients with benign glottic diseases. This study found significant voice improvements and low recurrence rates after phonosurgery.
Area of Science:
- Otolaryngology
- Laser Surgery
- Voice Science
Background:
- Benign glottic diseases can impair voice quality.
- Phonosurgery aims to restore vocal function.
- Carbon dioxide laser is a tool for laryngeal surgery.
Purpose of the Study:
- Evaluate glottic function after CO2 laser-assisted phonosurgery for benign laryngeal disease.
- Assess postoperative glottic morphology and disease recurrence.
- Determine the long-term effectiveness of laser-assisted phonosurgery.
Main Methods:
- Prospective non-randomized case series over 10 years.
- 235 patients with benign glottic pathology.
- Pre- and postoperative data: laryngeal examination, videostroboscopy, electroacoustic voice analysis, perceptual voice evaluation.
Main Results:
- Statistically significant improvement in objective voice parameters (P < 0.001).
- Postoperative morphology analysis showed three granuloma recurrences and one Reinke's oedema recurrence.
- Effective voice restoration achieved.
Conclusions:
- Carbon dioxide laser-assisted phonosurgery is effective for benign glottic disease.
- The procedure leads to significant voice improvement.
- Low recurrence rates observed in this cohort.
