Objective: To investigate the effecacy of cochlear implantation (CI) improving hearing of Lermoyez's syndrome, we retrospectively analyzed a case of Lermoyez's syndrome whose left ear was extremely severe sensorineural deafness and right ear was severe sensorineural deafness.
Method: The patient had completed preoperative audiological examination , vestibular function and imaging examination, then was carried out bilateral endolymphatic sac decompression and left side CI. Follow up after the surgery.
Result: The vertigo could be controlled very well after the bilateral endolymphatic sac decompression surgery, but the hearing loss couldn't be control, so CI was carried out to improve hearing and speech recognition rate. The contralateral hearing also improved significantly after the operation.
Conclusion: Endolymphatic sac decompression can effectively control. Ménière's disease in patients with vertigo attacks. CI can improve patients' hearing, and speech recognition rate and, also could improve the quality of life. CI was the first choice for the patient of 4 stage Ménière's disease.

Introduction: Endolymphatic sac tumor (ELST) is a rare neoplasm that exhibits aggressive growth primarily in the endolymphatic capsule and can potentially affect nearby neurovascular structures. The diagnosis of ELST poses challenges due to its low prevalence, gradual progression, and nonspecific symptomatology. It is currently believed that prompt surgical intervention is recommended for endolymphatic sac tumors upon diagnosis.

Endolymphatic sac tumors (ELSTs) are rare, slow-growing, and locally aggressive neoplasms that originate from the epithelial lining of the endolymphatic duct and sac. These are characterized by their infiltrative growth pattern and the potential for local destruction of surrounding structures, including the inner ear and temporal bone. We report a case of an incidentally diagnosed sporadic ELST.

Objective: Endolymphatic sac tumors (ELSTs), as rare low-grade neoplasms, are primarily treated with surgery. This study analyzes the characteristics of tumor-infiltrating leukocytes (TILs) in ELSTs and their relationships with clinical features to explore the potential for immunotherapy in ELSTs.
Methods: Clinical data and tumor specimens of 10 ELSTs patients who underwent surgery were retrieved.

Background: Meniere's disease (MD) is a disabling disease of the inner ear, having a substantial effect on a patient's quality of life. While various postulations regarding its aetiology exists, due to the difficulty with accessing inner ear tissue, there have been limited histological studies in patients with active MD.
Methods: Tissue was collected during labyrinthectomy from 8 patients with intractable MD who had failed medical therapy (22 samples), and 9 patients undergoing translabyrinthine resection of vestibular schwannoma (19 samples).

Objectives: Surgical treatments for Ménière's disease differ in efficacy. Endolymphatic duct blockage (EDB) is favored for its minimal risk and ability to preserve hearing. One of the main challenges in the technique is the difficulty in accurately identifying the endolymphatic duct (ED).
