Revision laryngeal surgery for the suboptimal injection of calcium hydroxylapatite.
OBJECTIVE
The objective of this study was to describe the management of suboptimal injection of calcium hydroxylapatite during augmentation laryngoplasty.


METHODS
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.


CONCLUSIONS
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.
