Management of the Mastoid Cutaneous Fistula | Chapter 13 | Current Progress in Medicine and Medical Research Vol. 5

 This affiliate highlights to develop an persuasive technique for the conclusion of the mastoid cutaneous fistula and to prevent the recurrence of the fistula & prevent further complications.A uncommon incessant otitis media (COM) importance called post-auricular mastoid cutaneous fistula (PAMCF) can expand after troublesome mastoid surgery and extremely seldom after congenital cholesteatoma. Due to deadly skin edges, simple closures have a meaningful failure risk. Therefore, several methods for the closure of this fistula have existed described. Post hearing fistula after canal divider down (CWD) mastoidectomy maybe successfully treated by fistula area excision and obliterating the mastoid cavity. The mastoid-cutaneous fistula afterwards mastoid surgery demands regional flaps for repair and a vascularized flap to prevent the loss of avascular tissue because skilled is insufficient fabric locally to repair the fistula. The fistula developed subordinate to the disease maybe managed surgically along with the affliction. The PAMCF, following radical mastoidectomy surgery, may happen due to noncompliance of the patient, not gone for follow up following radical mastoidectomy, repetition of the disease, residual ailment. Post auricular cut is given encircling the fistulous hole. Anterior and posterior flaps are elevated.  The fistulous  lot  extending  into  the  mastoid  cavity  is detached in toto.The incomplete  affliction  clearance  all along  mastoidectomy  has been recognized as a coarse cause of failure in patients, accompanying or without cholesteatoma. The earlier based vascularized pedicled temporalis muscle flap guarantees the viability of the flap and forestalls the necrosis of the skin edges, thereby countering the recurrence of the fistula. The temporo-mastoid fascio-cutaneous-periosteal advancement flap is persuasive for proper plug of the fistula and obliteration of the cavity by conchal piece of animate skeleton.
