Postauricular Cutaneous Mastoid Fistula Surgically Closed by a Temporalis Muscle Rotational Flap: A Case Report

Background: Postauricular cutaneous mastoid fistula (PCMF) is quite rare. Possible triggers include a radical mastoidectomy, chronic suppurative otitis media (CSOM), or the spontaneous exteriorization of cholesteatoma through postauricular skin surface. Case Report: This study reported 62-year-old woman who presented with right-sided discharging lesion for two years and history ear discharge over past 20 years. Physical examination revealed 10×8 mm pearly white tissue at opening mucoid discharge. Otoscopy represented an attic as potential underlying cause, computed tomography demonstrated soft-tissue density in middle extending into cavity towards area. The PCMF was surgically closed using temporalis muscle rotational flap no recurrence 6-month follow-up. Conclusion: Overall, surgical closure appears to be effective technique treating PCMF.
