Results of middle ear ventilation with Goode's tubes
Clinical Otolaryngology, 1989The results of a retrospective study of the effect and outcome of middle ear ventilation by Goode's tubes are presented. 83 ears from 50 patients were analyzed both as a group and in age-related sub-groups over a mean follow-up period of 1.83 years. The mean period of ventilation by Goode's tubes before removal or extrusion was 18.4 months.

A New Ventilation Tube for Long-Term Middle Ear Ventilation
Laryngoscope, 2002AbstractObjectives The treatment of secretory otitis media often requires repeated tubulation of the tympanic membrane as the standard ventilation tubes are extruded before the disease of the middle ear has remitted. The T‐tube and its modification have been developed to remain longer in situ, often requiring surgical removal.

Ventilation and clearance of the middle ear
The Journal of Laryngology & Otology, 2009AbstractObjective:To investigate the ventilation and drainage mechanism of the middle ear.Study design:Prospective.Setting:We observed 304 (of 337) middle ears with tympanic membrane perforation or myringotomy (102 normal, 90 with otitis media with effusion and 112 with chronic otitis media); 912 observations were recorded overall.

Middle Ear Ventilation Mechanism
Acta Oto-Laryngologica, 1990The ventilation mechanism of the middle ear is very important as regards the pathogenesis of middle ear disease, but its mode of function is still obscure. Therefore, we tried to measure the ventilation and clearance of the middle ear using radio-isotope imaging techniques and 133Xe in order to gain a clearer picture of the ventilation mechanism.

Normal and Abnormal Middle Ear Ventilation
Annals of Otology, Rhinology & Laryngology, 1977Studies in infants and children have suggested a functional rather than mechanical obstruction of the Eustachian tube as a predisposing factor in middle ear effusions (MEE). To simulate this condition in the laboratory, an animal model was prepared using juvenile Rhesus monkeys.

Membrane Ventilating Tube for the Middle Ear
Annals of Otology, Rhinology & Laryngology, 1976A pilot study was conducted to evaluate the efficacy of a membrane ventilating tube as a Eustachian tube prosthesis in 20 patients with otitis media. The design was based partly on assumptions since many of the physiological parameters required to calculate the gas transport processes have not been previously reported. An elementary gas transport model

Ventilating tubes in the middle ear.
Archives of otolaryngology (Chicago, Ill. : 1960), 1976One hundred children from 1 to 14 years of age had serous otitis media, the manifestations of which were bilateral in all but four patients. Thus, 196 ears were treated with aeration of the middle ear by means of a short transmyringeal tube. The mean duration of the treatment was 3.4 years, and the mean observation time was 7.3 years.

The Laryngoscope, 1974
AbstractTwenty years have now passed since the first tube was placed through the tympanic membrane for middle ear ventilation. In this relatively short period of time, many different ideas for tube design have emerged and are presented. The types of middle ear fluid formation and the relationship of this formation to impaired eustachian tube function ...

Middle Ear Ventilation in Secretory Otitis Media
Annals of Otology, Rhinology & Laryngology, 1976The Eustachian tube function was determined repeatedly in 42 patients during as well as after the course of secretory otitis media. Air pressure equalization technique and impedance audiometry were used. Also the size of the mastoid air cell system was determined. It was found that poor tubal function and a small mastoid air cell system are significant
