Tympanic membrane changes in central tympanic membrane perforations
American Journal of Otolaryngology, 2005The objective of this study was to evaluate the histopathological changes in central tympanic membrane perforations caused by chronic otitis media without cholesteatoma.Twenty-nine temporal bones from 25 patients (13 male patients and 12 female patients) with central tympanic membrane perforations-18 chronic otitis media with perforation and 11 chronic

Tympanic Membrane Perforation: Effect on Audiogram
Archives of Otolaryngology - Head and Neck Surgery, 1972The effects of both size and location of tympanic membrane perforations on hearing loss were studied. Using only those cases in which the air-bone gap was closed by myringoplasty, the variable of ossicular chain defects was controlled. Definite trends appeared in averages of the groups which tend to confirm two generalizations: (1) Effectiveness of the

PERFORATING BURN OF THE TYMPANIC MEMBRANE
Archives of Otolaryngology - Head and Neck Surgery, 1948ACCIDENTAL burn of the tympanic membrane is uncommon. Recent bibliographic summaries do not mention it. Beck described a case in which the tympanic membrane had been destroyed by pure phenol which was instilled into the ear by a soldier in an attempt to avoid front line service. Recovery was good.

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.

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
