AKURASI PREOPERATIF HIGH RESOLUTION COMPUTED TOMOGRAPHY (HRCT) TULANG TEMPORAL TERHADAP TEMUAN INTRAOPERATIF PASIEN OTITIS MEDIA SUPURATIF KRONIK (OMSK)
Background: High-resolution computed tomography (HRCT) imaging of the temporal bone prior to mastoidectomy is a routine examination in the field of Otorhinolaryngology–Head and Neck Surgery (ENT-HNS). HRCT findings play an important role in the medical and surgical management of patients with chronic suppurative otitis media (CSOM). In addition, HRCT can serve as the basis for planning the surgical approach. The aim of this study was to determine the accuracy of HRCT imaging prior to mastoidectomy at Mohammad Hoesin Hospital. Methods: An observational analytical study with a diagnostic test design was conducted at Mohammad Hoesin Hospital from June to August 2025. Thirty-two samples of patients with CSOM who had undergone mastoidectomy surgery and met the inclusion and exclusion criteria were obtained. Results: The accuracy between HRCT temporal bone images and intraoperative findings for the sigmoid sinus was 93.75% for the Halfmoon type, 100% for the protrusive type, and 93.75% for the saucer type. For mastoid pneumatization, the accuracy was 90.62% for the sclerotic type, 90.62% for the diploic type, and 100% for the pneumatic type. For pathological tissue, the accuracy was 96.88%. Accuracy for other structures was 96.88% for the scutum, 90.62% for the tegmen, 100% for the facial nerve canal, 93.75% for the lateral semicircular canal, and 96.88% for the ossicles. Conclusion: There is a high degree of accuracy between HRCT temporal bone findings and intraoperative mastoidectomy findings. Keywords: HRCT, Mastoidectomy
