Objectives: Endolymphatic sac decompression surgery (ESDS) is one of the surgical methods for intractable Meniere’s disease (MD), and it is known as a relatively safe treatment that does not cause hearing loss. However, the effectiveness and the degree of vertigo control rate of ESDS are still controversial.
In this study, we aimed to evaluate the clinical outcomes of ESDS in intractable MD.
Methods: We retrospectively reviewed 33 patients who underwent ESDS for intractable MD from January 2002 to March 2022. Clinical characteristics of patients, pure tone threshold, medical treatment method, and number of vertigo attacks before and after surgery were assessed. The improvement of hearing and vertigo was evaluated according to the 1995 American Academy of Otolaryngology- Head and Neck Surgery criteria.
Results: Of the 33 patients, the average follow-up period was 21.2 months, with immediate follow-up within 2 months (28 patients), short term between 2 and 6 months (27 patients), and long term at 12 months or later (29 patients). In the immediate hearing threshold, both air conduction and bone conduction showed slight deterioration, but there was no significant change in the long-term hearing threshold. At long-term follow-up, 12 patients (41.4%) were able to live without medication, and 18 patients (62.1%) showed improvement in their vertigo symptoms.
In addition, patients who showed improvement in hearing also showed improvement in vertigo at the same time.
Conclusions: ESDS in intractable MD is a relatively safe and effective treatment method for reducing vertigo attack without worsening hearing threshold.
