Predictive factors for postoperative outcome after endolymphatic sac surgery. Part 2: Quality of life.

OBJECTIVE

To evaluate improvement in quality of life (QoL) 2years after endolymphatic sac surgery (ESS) in patients with Ménière's disease (MD), and preoperative factors for QoL.

MATERIALS AND

METHODS

A retrospective single-center study included patients who underwent ESS between 2015 and 2022, with unilateral MD according to the criteria of the American Academy of Otolaryngology - Head and Neck Surgery (AAO-HNS) as revised in 2015, and resistant to first-line medical treatment. The main study endpoint was quality of life, measured on the MDOQ-R questionnaire.

RESULTS

Thirty-eight patients were included. Mean improvement in MDOQ-R score was 31.1±24.6 points [range: -29 to 79], and was significant (P<0.001). No predictive factors were identified.

CONCLUSION

ESS provided significant and lasting improvement in quality of life. However, it was not possible to identify preoperative predictive factors for a "typical" patient profile with the highest likelihood of favorable outcome.
