Abstract

Objectives/Hypothesis: To evaluate the effect and safety of the 532nm Pulsed Potassium-Titanyl-Phosphate (KTP) laser in the office-based treatment of patients with Reinke's edema using objective and subjective scaled outcome measures. Study Design: Case Series. Setting: Tertiary hospital center. Subjects: Seven adult females undergoing in-office KTP laser treatment for Reinke's edema. Methods: Participants were studied pre- and posttreatment. Vocal function was evaluated by objective aerodynamic and acoustic analysis. Subjective changes were evaluated using the GRBAS scale, Voice Handicap Index, and videostroboscopy. Histologic effects of the laser were investigated by comparing one patient treated with laser one year prior to excision, one treated with laser just prior to excision, and one control patient who underwent excision without prior laser treatment. Results: At an average postoperative follow up of 17.8 weeks (range 5-78), maximum phonation time trended toward improvement. The median VHI score decreased from 37 to 26 (p=0.150). There was a reduction in each component of the GRBAS scoring and the median fundamental frequency increased from 162 to 186 (p=0.625). Stroboscopic findings demonstrated an intact posttreatment mucosal wave. Histologic comparison of the tissue effects of laser in three patients demonstrated changes in vocal fold vascularity but no acute or long-term damage to the overlying epithelium. Conclusion: Objective and subjective scaled measures suggest that treatment of Reinke's edema in the office with a 532nm KTP laser may result in improved voice. It appears safe with histologic preservation of the vocal fold vibratory epithelium and persistence of mucosal wave.
