Canal wall prosthesis--new devices.
In our experience, management of the troublesome mastoid cavity a "rehabilitation" of the middle ear, usually involves post canal wall reconstruction. The purpose of the long canal wall reconstruction is to restore the anatomy as perfectly as possible in order to induce satisfactory wound healing of both epidermal a mucosal layers. The numerous materials and different surgical procedures to date, demonstrate the difficulty of reconstruction of the ear canal. Over twenty years we have performed 386 cases using various materials: cortical bone, ear canal allograft, ceravital, porous and dense hydroxylapatite. More recently to improve the anatomical results we have used a new titanium prosthesis. The pros and cons of each device are discussed.
