摘要

Benign vocal fold lesions often cause significant dysphonia and may require surgical excision to restore voice quality. Precision techniques such as coblation and microdebrider-assisted microlaryngeal surgery have been introduced to excise lesions while minimising injury to normal tissue. We present a case series assessing voice outcomes after these methods. In this retrospective series, consecutive patients with benign vocal fold lesions underwent microlaryngeal surgery using either coblation or microdebrider techniques. Pre- and postoperative assessments included stroboscopy, the 30-item Voice Handicap Index (VHI-30), and acoustic measures (percent jitter and shimmer). Paired statistical tests compared pre/post values. Ten patients (mean age 42 years, 6 men) were treated (five coblation, five microdebrider). Mean VHI-30 improved from 40.3 ± 9.1 to 17.4 ± 5.8 (p < 0.01), while mean jitter decreased from 1.51% to 0.76% and shimmer from 6.50% to 3.18% (both p < 0.05). These improvements mirror prior reports of significant voice gains after phonomicrosurgery. No significant differences in final VHI or acoustic gains were found between the coblation and microdebrider groups. Both techniques had minimal blood loss and no complications. Coblation and microdebrider microlaryngeal excision yielded significant voice improvements with low morbidity. These precision approaches effectively preserve vocal function, consistent with literature on voice outcomes after benign lesion surgery.
