Abstract

Objective: The objective of this study was to describe the management of suboptimal injection of calcium hydroxylapatite during augmentation laryngoplasty.

Study Design: A retrospective review was conducted at four Voice and Swallowing centers to identify patients who had a suboptimal injection of calcium hydroxylapatite during augmentation laryngoplasty.

Results: Five patients (ages 19–75) were identified with an impaired voice secondary to a superficial injection of calcium hydroxylapatite or over-medialization of the true vocal fold. All patients underwent revision surgery with all experiencing subjective and objective improvement.

Conclusion: Microflap excision can lead to successful return of vibratory function after a suboptimal injection of calcium hydroxylapatite. Complete control of the initial injection is paramount to avoiding this complication.
