Abstract

Purpose

Laryngeal framework surgery, including medialization laryngoplasty and arytenoid adduction (AA), is expected to have a lasting or permanent effect in patients with unilateral vocal fold paralysis (UVFP); however, there are few reports about the long-term outcomes of AA. This study aimed to evaluate the long-term postoperative effects of AA surgery and examine its stability and reliability.

Methods

This study collected the voice handicap index (VHI) questionnaire from patients with UVFP who underwent AA more than 2 years previously. The VHI values preoperatively and 3 months postoperatively (early postoperative evaluation) were retrospectively calculated, and VHI values more than 2 years after surgery (late postoperative evaluation) were collected by mailing a sheet to the patients and asking to fill and return it. Possible influenced subscales such as age, sex, causes of UVFP, affected side, and surgeons were also analyzed.

Results

A total of 77 patients with UVFP who underwent AA had significantly lower early and late postoperative evaluations than preoperative evaluations. In 38 patients with no missing values, there were no significant differences between early and late postoperative evaluations, measured at a median of approximately 5 years. There were also no significant differences between early and late postoperative evaluations in any of the subscale groups.

Conclusion

Patients with UVFP who underwent AA surgery achieved stable voice improvement in the long term after surgery.
