Mastoid Obliteration: Autogenous Cranial Bone pÂte Reconstruction

Mastoid obliteration with autogenous cranial bone is a safe and extremely effective option for treatment of problematic canal wall-down mastoid cavities. Surgical techniques that include sterile harvest of the cranial bone graft mixed with antibiotic, revision of the cavity to expose viable native bone, inclusion of the epitympanic spaces in the obliteration, and complete coverage of the pAte with autogenous fascia have proven critical to successful outcome.
