COMPARISON OF PREOPERATIVE TEMPORAL BONE HRCT FINDINGS WITH INTRAOPERATIVE FINDINGS IN PATIENTS WITH CHOLESTEATOMA

Dr. Lham Dorjee, Dr. P. S. K. Thangaraj

Abstract


Objectives: Comparing Preoperative High resolution CT image of Temporal bone with intraoperative findings in
patients with chronic suppurative otitis media with cholesteatoma
Study Design: Prospective study
Methods: 50 patients with cholesteatoma presenting to ENT outpatient department at Government Rajaji Hospital
attached to Madurai Medical College between December 2017 and November 2018 were taken up for study.
Radiological findings were noted and extent of disease established, management was done accordingly.
Observation: The prospective cohort clinical study was carried out on 55 patients. Scutum erosion was visualized in all
patients and similar findings intra operatively. Incus appeared eroded on CT scan in 25(45.45%) of cases, whereas intra
operatively it was seen in 27(49.09%)
Conclusion: HRCT can act as a guide to the nature of disease, potential dangers and possible complications, and this
information can assist the surgeon in the choice of surgery to be performed and better advise the patient on the degree
of hearing attainable after surgery.
