Purpose: Compare the audiological results and postoperative outcomes of the endoscopic approach versus the endaural microscopic approach for treatment of attic cholesteatomas, using a randomized prospective model.
Materials And Methods: Eighty patients were consecutively enrolled in the study and randomized into two groups of treatment of 40 patients: Group A -tympanoplasty with a microscopic endaural approach; Group B -tympanoplasty with an exclusive trans-meatal endoscopic approach. Preoperative, intraoperative and postoperative outcomes were evaluated. Hearing was assessed preoperatively and at 1 month, 3 months and 6 months after surgery in both groups.
Results: There were no differences in the parameters analyzed (CT findings, patient age, disease duration, intraoperative cholesteatoma characteristics,) between the group A and B patients. No statistical difference between the two groups regarding hearing improvement, abnormal taste sensation, dizziness, post-operative pain and healing times emerged. Graft success rate was 94.5 % and 92.1 % for MES and ESS respectively.
Conclusion: Both microscopic and exclusively endoscopic endaural approaches offer similar and excellent results in the surgical treatment of attic cholesteatomas.

This study aimed to compare the efficacy of continuous perfusion of underwater bone grinding combined with a -shaped incision versus a microscopic posterior ear incision in the treatment of attic cholesteatoma. Clinical trials were prospective studies from the Northern Jiangsu People's Hospital. Adult patients with middle ear cholesteatoma requiring ear surgery agreed to participate between September 2019 and September 2023 (age > 18).

Objective: The surgical strategy of cholesteatomas is still controversial. This study aimed to compare the hearing improvement and determine the prognostic factors between endoscopic and microscopic ear surgery for attic cholesteatoma via a multicenter retrospective study.
Methods: This retrospective study included 169 patients with attic cholesteatoma who received endoscopic ear surgery (EES) or microscopic ear surgery (MES) from 12 otorhinolaryngology centers.

Conductive hearing loss with a normal tympanic membrane is a common reason for otolaryngology consultation, with otospongiosis being the most frequent cause and House syndrome being extremely rare, requiring systematic investigation. We report the case of a 31-year-old woman who presented with conductive hearing loss with a normal tympanic membrane. A temporal bone computed tomography (CT) scan confirmed a House-Goodhill syndrome due to fixation of the malleus head.

Cholesteatoma is a lesion capable of destroying surrounding tissues, which may result in significant complications. Surgical resection is the only effective treatment; however, the presence of cholesteatoma recidivism is common. This study evaluated the effectiveness of the Attic Exposure-Antrum Exclusion (AE-AE) surgical technique in treating cholesteatomas and identifying factors associated with recidivism.

Objective: Atticotomy represents an essential surgical step within the management of attical cholesteatoma during endoscopic ear surgery. The aim of the present study was to evaluate the safety and functional results of an endoscopic atticotomy performed with piezosurgery, in terms of audiological outcomes and tissue's healing.
Methods: This is an observational retrospective study on patients with attical cholesteatoma who underwent endoscopic ear surgery with piezoelectric atticotomy and subsequent scutum reconstruction either with tragal cartilage or temporalis muscle fascia.
