Tympano-nasopharyngeal shunt operation. A new method of middle ear ventilation. 1975

V K Misurya

The tympano-nasopharyngeal shunt operation is recommended as a "substitute" Eustachian tube. An experimental study regarding the efficacy of tympano-nasopharyngeal shunt operation was conducted in two dogs. Finally, four patients with complete tubal stenosis were operated on by this new method within a period of one year, with no postoperative complications. The hearing improved and patients were able to inflate their middle ears. The method is claimed to have the following advantages: permanent ventilation of the middle ear with preservation of an intact drum; the middle-ear pressure can be increased by Valsalva or Politzer manoeuvres; moderate technical difficulties; no risk of postoperative complications; and suitable in children as well as adults. The disadvantages seem to be: drainage not ensured; minor risk of ascending infection.
