Mastoid Obliteration: Histopathological Study of Three Temporal Bones

Obliteration of temporal dorsal bulla in guinea pigs using different types of calcium phosphate

“…Ear surgeons usually use local flaps, autologous cartilage, or some fatty tissues to fill the mastoid cavities [1][2][3][4][5]. However, in many cases it is difficult to obtain sufficient tissue to obliterate large cavities and sometimes these tissues can atrophy and involute as time goes on [3,16].…”

“…However, in many cases it is difficult to obtain sufficient tissue to obliterate large cavities and sometimes these tissues can atrophy and involute as time goes on [3,16]. As a result, synthetic bioactive materials are used to reconstruct mastoid defect.…”

“…And other problem that we could face with is big meatus which could cause cosmetic problems in some patients. Clinically bone, autologous fat, cartilage and several local flaps are used to obliterate the mastoid cavity [1][2][3][4][5]. Some alloplastic materials such as hydroxyapatite and demineralized bone, have been used to fill the bony cavity defect [6][7][8][9][10][11][12][13][14][15].…”

“…Some alloplastic materials such as hydroxyapatite and demineralized bone, have been used to fill the bony cavity defect [6][7][8][9][10][11][12][13][14][15]. However, some autologous materials or flaps can be dissolved over time and other alloplastic materials may not to be suitable to use because of their appearances and possibility for a foreign body reaction [3][4][5][6][7][8][9][10][11][12][13][14][15][16].…”
