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 perforations in children
International Journal of Pediatric Otorhinolaryngology, 1996We have assessed children with perforations of the pars-tensa presenting to an otolaryngology clinic over a 7-year period. We found that over 70% of the perforations followed the insertion of a ventilation tube. Using a novel method of dividing the tympanic membrane into quadrants, we were able to assess the sites and grade the size of perforations ...

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.

Closure of Tympanic Membrane Perforations
Archives of Otolaryngology - Head and Neck Surgery, 1962The repair of central perforations of the tympanic membrane was seldom attempted and received little mention prior to World War II. Due to the impetus of the large number of traumatic drum injuries during this period, more interest has been focused on closure in the past 15 years. The ear must be dry before closure is attempted, although the length of

Histology of the Tympanic Perforation and the Replacement Membrane
Acta Oto-Laryngologica, 1985This study shows that the mucocutaneous junction of a perforation of the tympanic membrane may be located at the margin, in the middle ear, or in the ear canal. It is incumbent upon the surgeon performing myringoplasty to identify this junction in order to optimize the success of surgery.

Polyvinyl in Tympanic Membrane Perforations
Archives of Otolaryngology - Head and Neck Surgery, 1967A STUDY OF the use of a synthetic material in the repair of tympanic perforations of the middle ear was undertaken to determine if the use of such material would replace the use of autogenous tissue. The experiment was carried out on cats of adult age. The use of implants in various parts of the body is not new.

Tympanic membrane perforations
2018This chapter discusses Macfadyen, Acuin, and Gamble’s paper on systemic antibiotics versus topical treatments for chronically discharging ears with underlying eardrum perforations including the design of the study, (including outcome measures, results, conclusions, and a critique).

Tympanic Membrane Perforations and Tympanostomy Tubes
Annals of Otology, Rhinology & Laryngology, 1994Tympanoplasty and tympanostomy tubes were developed at the same time and have dramatically changed the treatment of chronic middle ear disease. One hundred forty-nine children who had tubes inserted between ages 6 months and 8 years for chronic otitis media with effusion have been prospectively followed up for an average of 4 years.

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

AlloDerm tympanoplasty of tympanic membrane perforations
American Journal of Otolaryngology, 2003To study the effectiveness of AlloDerm (LifeCell Corporation, Branchburg, NJ) as a graft material in underlay tympanoplasty by comparison to autologous fascia in a chronic tympanic membrane perforation animal model.Seventeen chinchillas underwent creation of bilateral chronic tympanic membrane perforations over a 6-week period.
