Polyvinyl in Tympanic Membrane Perforations

Archives of Otolaryngology - Head and Neck Surgery, 1967
A 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, 1962
The 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, 1985
This 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.

Photography in treatment of tympanic membrane perforations

The Journal of Laryngology & Otology, 1984
A 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.

Tympanic Membrane Perforations and Tympanostomy Tubes

Annals of Otology, Rhinology & Laryngology, 1994
Tympanoplasty 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, 2011
To 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 ...

Errors in the assessment of tympanic membrane perforations

Clinical Otolaryngology, 1993
It 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.

Acceleration of Healing of Traumatic Tympanic Membrane Perforation in Rats by Implanted Collagen Membrane Integrated with Collagen-Binding Basic Fibroblast Growth Factor.

Tissue Engineering. Part A, 2016
Traumatic tympanic membrane (TM) perforation is very common in clinical practice. Several biomaterials have been reported to play a role in TM reparation, whereas their functional recovery is limited when used alone.

Ventilation Tubes and Persisting Tympanic Membrane Perforations

Otolaryngology–Head and Neck Surgery, 1997
Surgical 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
