研究目的
To validate the efficacy of office-based potassium titanyl phosphate (KTP) laser ablation for vocal fold polyps (VFPs) in professional singers.
研究成果
Office-based KTP laser treatment provided complete resolution of small- to medium-sized VFP with improvement in SVHI-10 and without perceivable negative impact on vocal fold vibration. All patients resumed their professional singing careers without limitations in their singing voice.
研究不足
The study is limited by the relatively small number of patients and the timing of follow-up visits, which may not precisely determine the true resolution time. It lacks a control group, and the resolution time may be earlier than reported.
1:Experimental Design and Method Selection:
A consecutive series of six professional singers with seven episodes of VFP underwent in-office KTP laser ablation based on patient and provider preference.
2:Sample Selection and Data Sources:
Patients seen at the University of Texas Voice Center who earn a living as professional singers.
3:List of Experimental Equipment and Materials:
KTP laser, laryngoscope, laser catheter, and KTP fiber.
4:Experimental Procedures and Operational Workflow:
Patients underwent informed consent, topicalization of nasal cavity, laryngotracheal anesthesia, and laser ablation. Voice conservation was recommended post-treatment.
5:Data Analysis Methods:
Pre- and posttreatment VHI-10 and SVHI-10 were compared using Wilcoxon Rank Sum.
