A Case of Repair of Retroauricular Skin Defect and Mastoid Cavity with Posterior Wall Reconstruction Using Tutoplast(R)(Allograft Cancellous Bone Chip) and Bone Dust after Canal Wall Down Mastoidectomy / 대한이비인후과학회지

ABSTRACT

Canal wall down mastoidectomy is often selected for the complete eradication of lesion and prevention of recurrence in patients with cholesteatoma. However, potential complications include a chronically draining cavity, retention of debris that requires frequent cleaning, difficulty with fitting a hearing aid. Aimed at solving these problems, surgeons have attempted reconstruction with a variety of techniques and materials: the reconstruction of an anatomically correct canal wall and complete obliteration of the mastoid cavity. We recently experienced a case of a retroauricular skin defect and cavity after canal wall down mastoidectomy of a 58-year-old male patient. The skin defect and cavity were repaired using a local skin flap, mastoid obliteration and posterior wall reconstruction methods using Tutoplast(R)(Allograft cancellous bone chip). We report this along with a review of literature.
