Abstract:
Objective:This study aims to explore the clinical effectiveness of a novel treatment method for refractory laryngeal contact granuloma, involving CO2 laser excision with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. Methods:A retrospective analysis was conducted on 18 patients with refractory laryngeal contact granuloma who visited Department of Otolaryngology Head and Neck Surgery, Nanjing Tongren Hospital, School of Medicine, Southeast University from January 2021 to June 2023. These patients underwent CO2 laser excision of the granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection. During follow-up, electronic laryngoscopy were performed at 1, 3, 6, and 12 months postoperatively, and local laryngeal mucosa, voice quality, and pharyngeal discomfort symptoms were evaluated. Results:Postoperative electronic laryngoscopy revealed the disappearance of granulomas in all 18 patients. Symptoms such as hoarseness, foreign body sensation in the throat, and cough were significantly improved. No complications were observed systemically or locally. No recurrence was observed during one-year follow-up. Conclusion:CO2 laser excision of granuloma with local pedicled mucosal flap transfer combined with type A botulinum toxin injection could eliminate the lesion, restore the integrity of the vocal fold lining, preserve the perichondrium, and provide a time window for mucosal flap recovery. This approach adheres to the principle of preserving normal mucosa, achieves a high cure rate, and is therefore worthy of widespread promotion and application in clinical practice.
