Otosclerosis  Lindsay et al.139 present the histopathology in 5 patients successfully operated on for bilateral otosclerosis. Fenestration was performed on one ear in 4 patients, and stapes mobilization on both ears in 1. Four examples of a fenestra bore out certain principles which have been indicated by animal experiments and clinical experience in man. The fenestra should be placed on a convex surface to promote closer adherence of the flap. Stripping of endosteum from the bone at the margins of the fenestra should be avoided. It is advantageous to have a sharp edge to the fenestra to obtain close approximation between the endosteal margin and undersurface of the flap. One patient illustrated that in the presence of a well-prepared fenestra, a tear and gap in the membranous canal may be compatible with a good result. Three of these 4 fenestrations demonstrated the permanence of the well-prepared fenestra and the
