The International Journal of Artificial Organs, 1980
Artificial eardrums made from biodegradable poly(D, L-lactic acid), poly(glycolic acid) and poly(ß-benzyl-L-aspartate-co-L-leucine) 50/50, and made from the microporous poly(tetrafluoroethylene) and bisphenol-A poly(carbonate) membranes were implanted into the ear and as a reference subcutaneously in rats.

AbstractThis retrospective study was undertaken to review the short- and long-term results of 70 revision and 16 re-revision myringoplasty operations. Of the former, 43 cases (61.4 per cent) had initial success, six weeks following surgery. The leading causes of immediate failure (27 cases) were associated with a complete no- take of thegraft ...

Clinical Otolaryngology, 1976
Myringoplasty is a deceptively difficult procedure in which surgical finesse and experience dictate success in terms of hearing improvement as well as closure rate. In essence, it is the complete removal of epidermal ingrowth followed by the placement of a non-epithelialized graft on the medial surface of the tympanic membrane which has withstood the ...

Heterograft myringoplasty on dogs was performed. Serosa of the cecum of the calf was used in eight middle ears and cadaver tympanic membrane of the calf with the malleus attached in four. All canine eardrums were healed 10 to 12 weeks postoperatively. The heterografts were then unidentifiable.

Auris Nasus Larynx, 1991
Our 11 years of experience of myringoplasty in 87 children aged 3 to 14 years were retrospectively studied. The children were followed up over a period of 3 years. Children in the 3-to-12-year-old age group had a success rate of 57.7%. Graft-take rate was 100% in children operated on at the age of 13 and 14 years. Revision surgery was needed in 33 ears,

Introduction: Perforations of the tympanic membrane result mainly from otitis media or trauma, and we need grafting when a perforation is chronically persistent to prevent recurring infections and to enhance hearing. In the present study, we assessed the success rate, feasibility, and efficacy of endoscopic transcanal tympanoplasty using tragal ...

Tympanic perforations can be determined mainly by acute and chronic otitis, or ear trauma. These defects can possibly heal spontaneously. A persistent perforation represents not only an anatomical but also a functional defect, requiring surgical correction in most of the cases.

Tympanoscope-Assisted Myringoplasty
ORL, 2001Thirty ears of 29 patients with different sized perforation of the tympanic membrane were operated on with the aid of rigid otoendoscopes. The technique has a significant novel feature: endoscopy of the tympanic cavity through a perforation with small tympanoscopes 1.7 mm in diameter with a 0%.

A simple technique for closing small-to-medium sized perforations of the tympanic membrane in the Out-Patient Department has been described. Homograft temporalis fascia was used as a graft material. In a series of eighteen patients a closure rate of 78.2 per cent was obtained. The advantages of the method have been discussed.

We analyzed those failures occurring in 417 myringoplasties. Forty-four drum re-perforations were found (10.6%), half of which occurred immediately after operation. Causes of these early failures included necrosis in the middle of the graft without infection (10 ears) and blunting of the anterior margins of the graft (7 ears).
