Abstract :
Tympanic membrane perforation is the most commonly seen pathology encountered by an otolaryngology surgeon. In underlay technique of tympanoplasty, mucosalization of the graft many a times leads to continuous or intermittent discharging ear despite an intact tympanic membrane “Red Drum Conundrum”. Total annulus excision (TAE) implies that the entire annulus is removed along with remnant of tympanic membrane during the procedure to surgically reconstruct a diseased membrane. TAE is an essential step of a broader technique of interlay technique. This novel Interlay technique’s basic premise is that - Once the graft is placed, there must not be any mucous membrane lateral to the graft and no epithelium medial to the graft. One very important benefit of TAE is neovascularization around the graft. Total annular excision is a new emerging technique of tympanoplasty as it gives patient a three layered physiologically and anatomically near natural membrane with good vibratory function without possibility of weeping membrane or granular myringitis.
