Audiologic Improvement Following MCF Approach for Spontaneous Cerebrospinal Fluid Leaks
Objective:
To determine the audiologic improvement after middle cranial fossa (MCF) approach to repair spontaneous cerebrospinal fluid (sCSF) leaks.
Study Design:
Retrospective cohort study.
Setting:
Tertiary referral center.
Patients:
Twenty-four consecutive patients (27 ears) with temporal bone sCSF leak over a 4-year period. Patient age, sex, ethnicity, body mass index (BMI), location of CSF leak, recurrence of CSF leak, and presence of encephalocele(s) were recorded.
Intervention:
Audiometric testing in patients undergoing MCF repair of temporal bone sCSF leak.
Main Outcome Measures:
Comparison of preoperative and postoperative pure-tone average (PTA), air-bone gap (ABG), and word recognition score (WRS) in the sCSF leak ear.
Results:
Out of 27 ears, 55% had multiple tegmen defects and 82% had more than or equal to 1 encephaloceles. There were no recurrent CSF leaks at a median follow up of 4 months. The mean (SD) preoperative PTA and ABG were 40.58 [15.67] and 16.44 [6.93] dB, respectively. There was significant improvement in mean PTA (10.28 [8.01] dB; p
