Associations of Pre- and Intraoperative Endoscopic Findings of Middle Ear Status in Cholesteatoma

Middle Ear Status in Cholesteatoma: the Associations of Preoperative Computed Tomography Scans, Audiologic Assessment, and Intraoperative Endoscopic Findings

The aim of this study is to assess the accuracy of preoperative HRCT of the temporal bone combined with the preoperative audiologic assessment compared with the intraoperative endoscopic middle ear finding.

The information of the preoperative HRCT scanning of the middle ear cavity in cholesteatoma combined with the preoperative audiologic assessment could be informed the intraoperative middle ear finding in the patients who were diagnosed with chronic otitis media with cholesteatoma, which influence the plan of surgical management. Whether these preoperative assessments can predict the intraoperative finding is unclear. The aim of this study is to assess the accuracy of preoperative HRCT of the temporal bone combined with the preoperative audiologic assessment compared with the intraoperative endoscopic middle ear finding.

Inclusion Criteria:

• The patients included in this study had otorrhea, hearing loss, or aural fullness that last more than 3 months. Otological examination revealed tympanic membrane perforation or retraction, along with cholesteatoma.

Exclusion Criteria:

• Patients who had a previous temporal bone fracture, concomitant with congenital craniofacial anomalies, or underwent previous otologic surgery were excluded.
