Abstract

Contact granuloma of the vocal fold is a benign lesion that can be challenging to treat, often requiring multiple interventions. This case report presents the successful treatment of a refractory vocal fold contact granuloma using KTP laser vaporization under local anesthesia. A 30-year-old male patient with a persistent right vocal process granuloma, unresponsive to 3 months of conservative treatment, underwent in-office KTP laser surgery. The granuloma completely resolved within 1 month post-procedure, with improved voice quality and objective voice parameters. No recurrence was observed during the 6 months follow-up period. The in-office KTP laser vaporization technique provides a viable alternative for treating refractory vocal fold granulomas, particularly in patients who are unsuitable for general anesthesia or voice professionals who cannot tolerate prolonged voice rest following botulinum toxin injections. However, as this is a single case report, larger prospective studies with standardized follow-up periods are necessary to determine long term efficacy and recurrence rates.
