Middle Ear Irrigation During Insertion of Ventilation Tubes

Auris Nasus Larynx, 1985
Tympanostomy and insertion of ventilation tubes has become one of the most commonly performed operations in the United States. Most authors reporting complications of this procedure describe a postoperative rate of otorrhea in the range of 10-20% with some reports much higher.

Tympanomaxillary Shunt: A New Method of Middle Ear Ventilation

Archives of Otolaryngology - Head and Neck Surgery, 1969
INSUFFICIENT ventilation through the eustachian tube is one of the main causes of middle ear pathology and hearing loss. A dysfunction of the tube is always present in chronic serous otitis and very often in chronic otitis, in which case the result of a tympanoplastic procedure may depend on the ventilatory capacity of the tube.

The Middle Ear Gas Composition in Air-Ventilated Dogs

Acta Oto-Laryngologica, 1980
The middle ear gas composition has been examined in 5 air-ventilated dogs under sodium thiopentone anesthesia. The gas samples were obtained by transtympanic puncture and analysed by gas chromatography. The following mean +/- S.D. gas composition was obtained: N2 83.2 +/- 5.0; O2 12.1 +/- 2.2; and CO2 4.7 +/- 0.7.

Study of the Ventilation of Middle Ear Using Radioactive Xenon

Annals of Otology, Rhinology & Laryngology, 1976
The greatest contribution of nuclear medicine has been to make possible dynamic measurements of regional function. It is conceivable that if this technology could be successfully used to measure the ventilation and clearance of the middle ear, answers to some of the most crucial problems in otology may be found.

Effects of Large‐Bore Middle Ear Ventilation Tubes

Otolaryngology–Head and Neck Surgery, 1980
Patients with chronic otitis media that did not respond to conventional treatment were studied for the types and incidence of complications from the use of large‐bore tubes inserted into their ears. The most common complication was otorrhea (41%, 50 of 123 ears). Permanent perforation occurred in 25% (17/68 ears).

Ventilating Tubes in the Middle Ear: Long-term Observations

Archives of Otolaryngology - Head and Neck Surgery, 1984
This follow-up study is of the same patients we studied in 1976. Then we thought the results were unsatisfactory in 20.9% of the ears treated with ventilating tubes. The hearing losses varied from 25 to 60 dB and chronic otitis media developed in 7.7% of the cases.

Gas composition of the normal and the ventilated middle ear cavity

Scandinavian Journal of Clinical and Laboratory Investigation, 1987
Epidemiologic and controlled studies indicate that late minimal hearing impairment is a sequelae after the use of a ventilation tube in early childhood. The patho-physiology is unknown, but abnormal middle ear gas composition might be important. Therefore it is mandatory to measure middle ear gas composition in order to understand the gas exchange in ...

Long-term middle-ear ventilation with subannular tubes

The Journal of Laryngology & Otology, 2010
AbstractObjective:Long-term tympanostomy tubes are associated with a significant rate of complications, particularly persistent perforation. We describe the outcomes of 57 subannular ventilation tube insertions in 45 consecutive patients.Design:Retrospective case series.Subjects:We studied 45 consecutive patients with chronic otitis media with effusion

Otitis Media, Cleft Palate, and Middle Ear Ventilation

Otolaryngology–Head and Neck Surgery, 1981
Chinchillas with unilateral tympanostomy tubes in place underwent palate‐clefting in an effort to determine the histologic and bacteriologic effects of using tympanostomy tubes in the treatment of otitis media. The tympanostomy tube appeared to almost totally eliminate the occurrence of middle ear effusion but had much less, if any, effect on ...

Cholesteatoma in Relation to Middle-Ear Ventilation

2001
As is well known, middle-ear cholesteatoma is one of the most serious middle-ear inflammatory diseases. It invades deeply into the surrounding structures by absorbing the bone, causing various complications, and it sometimes recurs after surgery.
