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.

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

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.

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.

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.

Regenerative Treatment for Tympanic Membrane Perforation
Otology & Neurotology, 2011To establish a tissue engineering therapy for the treatment of large tympanic membrane perforation (TMP) without the need for conventional surgical therapy.Randomized control trial.General hospital.A total of 63 chronic TMPs were randomly selected from outpatients.Of the total 63 chronic TMPs, 53 were randomly assigned to the basic fibroblast growth ...

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.

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

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.

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
