Tympanoplasty for sinus tympani retraction may result in delayed recurrence of the original problem. This is especially true in children with marginal eustachian tube function. Autogenous tragal cartilage, scored on one surface with perichondrium attached on the other, produces a "natural bend" in the cartilage. When placed in the middle ear, with the scored convex surface facing the promontory, retraction into the sinus tympani can be prevented. This simple, yet effective, surgical technique is outlined.
