Vocal Fold Medialization Procedures in Previously Radiated Patients: A Survey of Practice Patterns.

BACKGROUND/OBJECTIVES: Head and neck radiation therapy (HNRT) has traditionally been considered a contraindication to vocal fold medialization procedures. Although safety has been demonstrated, we hypothesize that actual management varies. This study evaluates practice patterns of otolaryngologists regarding vocal fold medialization in patients after HNRT.

METHODS

A 25-question survey evaluating respondents' management of patients status post HNRT with vocal fold paresis/paralysis was distributed to 357 otolaryngologists. Practice patterns regarding injection laryngoplasty (IL), medialization thyroplasty (MT), and arytenoid adduction (AA) were queried.

RESULTS

Eight-two clinicians (23%) completed the survey. Ninety-one percent of respondents were laryngologists, 9% head and neck surgeons, 3% comprehensive otolaryngologists, and 3% "other." Eleven (15%) had been in practice <5 years, 19 (25%) for 5-10 years, and 46 (61%) for >10 years. No respondents considered HNRT a contraindication to IL, and 11 (14%) reported complications from the procedure. Hyaluronic acid (58, 75%) was most commonly injected. Twenty percent considered HNRT a contraindication to MT, and 37% considered it a contraindication to AA. Gore-Tex was used most commonly (65%). Twenty-seven percent reported major complications after MT. All complications occurred in the >10-year practice group, and this group was more likely to delay surgery after HNRT (p = 0.022). Respondents with complications were more likely to perform MT in HNRT patients (p = 0.0191).

CONCLUSIONS

Otolaryngologists generally do not consider HNRT to be a contraindication to IL, but some consider it a contraindication to MT/AA. Previous complications do not appear to deter surgeons from performing MT.
