Comparison of different tympanic membrane reconstruction techniques in type I tympanoplasty.
Summary of "Comparison of different tympanic membrane reconstruction techniques in type I tympanoplasty."
The objective of the study was to assess the functional results after type I tympanoplasty with temporal muscle fascia, perichondrium/cartilage island and cartilage palisades. The records of 120 patients who underwent type I tympanoplasty operation between January 2003 and June 2007 were retrospectively reviewed. This study aimed to comprise a homogeneous group of patients to make the comparisons as accurate as possible. For this purpose, primary tympanoplasty cases with subtotal perforations, intact ossicular chain, dry ear for a period of at least 1 month, and normal middle ear mucosa were included in the study. Patients younger than 15 years of age and patients with cholesteatoma were excluded. Temporal muscle fascia was used in 67 (55.8%), perichondrium/cartilage island flap was used in 34 (28.3%), and cartilage palisades were used in 19 (15.8%) of the patients. Pre- and postoperative otoscopic examinations, pure-tone averages, and air-bone gaps were compared pre and postoperatively. Concerning all of the cases, the graft take rate was 85% (102/120). In the perichondrium/cartilage island flap group, the graft take rate was 97.7%, whereas the graft take rates for the fascia group and cartilage palisades group were 80.6 and 79.0%, respectively. In the perichondrium/cartilage island flap group, the pure-tone average was 36.36 dB, whereas the pure-tone averages for the fascia group and cartilage palisades group were 36.07 and 39.79 dB, preoperatively. The postoperative pure-tone averages were 24.54 dB fort he perichondrium/cartilage island flap group, 24.51 dB for the fascia group and 23.23 dB for the cartilage palisades group. Cartilage grafting is not only more enduring against infection and negative middle ear pressure but also it has low re-perforation rates on long-term follow-up. Thus, cartilage may be preferred more often for primary tympanoplasties with high graft rate and hearing improvement.

To compare two methods of tympanic membrane (TM) grafting when graft materials medial or lateral to malleus, this study have been done.
We wished to determine if the success of lateral graft tympanoplasty was affected by either size of perforation, previous underlay tympanoplasty, or patient age.
We describe a series of 11 patients-8 men and 3 women, aged 18 to 70 years (mean: 46.0)-who had fungal otitis externa that had been complicated by a tympanic membrane perforation. These patients had b...

Surgical reconstruction of the hearing mechanism of the middle ear, with restoration of the drum membrane to protect the round window from sound pressure, and establishment of ossicular continuity between the tympanic membrane and the oval window. (Dorland, 28th ed.)
A mobile chain of three small bones (INCUS; MALLEUS; STAPES) in the TYMPANIC CAVITY between the TYMPANIC MEMBRANE and the oval window on the wall of INNER EAR. Sound waves are converted to vibration by the tympanic membrane then transmitted via these ear ossicles to the inner ear.
A temporary or persistent opening in the eardrum (TYMPANIC MEMBRANE). Clinical signs depend on the size, location, and associated pathological condition.
An oval semitransparent membrane separating the external EAR CANAL from the tympanic cavity (EAR, MIDDLE). It contains three layers: the skin of the external ear canal; the core of radially and circularly arranged collagen fibers; and the MUCOSA of the middle ear.
