Hearing loss in perforations of the tympanic membrane
The Journal of Laryngology & Otology, 1979Abstract70 Patients with dry central perforations have been studied to assess the hearing loss. The hearing loss is greater at the lower frequencies and increases with the size of the perforation. Malleolar perforations cause more hearing loss than the non-malleolar unless the perforation involves less than 10 per cent of the tympanic membrance surface

Repair of Experimental Tympanic Membrane Perforations
Acta Oto-Laryngologica, 1980In this investigation the healing pattern of experimental central and marginal pars tensa perforations in cats and rats was studied by using light and scanning electronmicroscopic techniques. The perforations were closed by hyperplastic squamous epithelium exhibiting a marked keratin production.

[Tympanic membrane perforation ].
Duodecim; laaketieteellinen aikakauskirja, 2014Tympanic membrane perforation may be caused by, e.g., trauma or acute or chronic middle ear infection. Perforation causes conductive hearing loss. Since it predisposes to infections, it is important to keep the ear dry. In most cases traumatic perforations heal spontaneously.

Errors in the assessment of tympanic membrane perforations
Clinical Otolaryngology, 1993It is commonly stated that operative closure of large perforations of the tympanic membrane is less successful than closure of small perforations. Few authors mention the exact size of the perforations studied, and fewer still give their method of measuring perforations.

The perforated tympanic membrane.
American family physician, 1992Tympanic membrane perforations typically result from trauma or acute otitis media. Most perforations do not cause more than a mild conductive hearing loss, aural fullness and mild tinnitus. Blood, purulent secretions and other debris should be carefully suctioned out of the canal and the perforation size and location described. Irrigation and pneumatic

Photography in treatment of tympanic membrane perforations
The Journal of Laryngology & Otology, 1984A photographic method which gives a large image on the film is used for recording perforations of the tympanic membrane and it may be valuable for comparing different methods of closure. A method for the treatment of minor perforations is also briefly mentioned.

Ventilation Tubes and Persisting Tympanic Membrane Perforations
Otolaryngology–Head and Neck Surgery, 1997Surgical management of otitis media with effusion and recurrent acute otitis media includes myringotomy and the use of ventilation tubes. Since this procedure was reintroduced by Armstrong in 1954, it has become one of the most commonly performed operations in otolaryngology. In most series perforation of the tympanic membrane in some patients has been

Tympanic membrane perforations.
Acta oto-rhino-laryngologica Belgica, 1995The recent literature on the healing of tympanic membrane perforations is reviewed. Research on the migratory phenomena, epithelial migration and keratin dispersion on top of the tympanic membrane, is discussed. The etiology and pathogenesis of tympanic membrane perforations is then briefly described.

REPAIR OF CENTRAL PERFORATIONS OF TYMPANIC MEMBRANE
Archives of Otolaryngology - Head and Neck Surgery, 1953THE REPAIR of central perforations of the tympanic membrane has received practically no mention in current textbooks of otolaryngology and had received relatively scant attention in the literature prior to World War II. However, rupture of the tympanic membrane as a wartime injury focused much more interest on the closing of perforations, and a review ...
