OBJECTIVES: The objective of this study was to evaluate the role of transnasal fiber-optic injection laryngoplasty in the treatment of glottic insufficiency.
METHODS: Video recordings of 16 patients who underwent fiber-optic injection laryngoplasty for the treatment of glottic insufficiency were reviewed. Outcome measures included perceptual evaluation using the GRBAS (grading, roughness, breathiness, asthenia, straining) classification, laryngeal videostroboscopy, and frame-by-frame analysis to assess the extent, shape, and duration of glottic closure.
RESULTS: Nine patients were ultimately included in this study. Their mean age was 66.2 years, with 7 men and 2 women. The most common symptoms were dysphonia and aspiration, and the most common diagnosis was vocal fold paralysis. Patients underwent transnasal fiber-optic injection laryngoplasty with hyaluronic acid as a filling material (0.2-0.8 mL). The procedure was well tolerated by all patients, with improvement in the phonatory symptoms and aspiration in 66.66% and 50% of patients, respectively. There were significant decreases in the mean scores of all perceptual parameters (P<.05 for all). All subjects had glottal gap preoperatively that was closed completely in 66.66% and reduced to <2 mm in 33.33%. The mean closed quotient significantly increased from 0.10 to 0.51 (P<.05).
CONCLUSIONS: Transnasal fiber-optic injection laryngoplasty is a safe procedure well tolerated by patients with good results.
