In all patients, tympanoplasty with cortical mastoidectomy was performed. The patency and dimensions of the aditus ad antrum were assessed using a 30\u00b0 endoscope. Biopsies were obtained from unhealthy mucosa to detect the presence of granulation tissue or occult cholesteatoma.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Ten cases (20%) had a blocked aditus ad antrum by unhealthy and edematous mucosa.
