Eustachian tube function was evaluated by sonotubometry in otologically normal young adults. The purpose of the research was to determine if the incidence or duration of eustachian tube opening would be altered with changes in swallowing bolus volume or changes in head rotation. The subject performed multiple swallows of 10 cc water bolus and dry swallows (saliva), with the head in the straight-forward, turned right, and turned left positions. Both ears were evaluated. The average Incidence and duration of eustachian tube opening for all swallows was 74% (398 msec). No significant differences were found with any combination of bolus type or head position, suggesting that neither liquid bolus volume nor head rotation need be controlled when sonotubometry is performed.

The purpose of this study was to develop instructions and procedures and to establish a normal data base for four tympanometric tests of Eustachian tube function: Valsalva, Toynbee, Inflation, and Deflation. Data were obtained for 24 young adults (48 ears) with normal hearing and normal middle-ear function. The tympanograms were analyzed for differences between baseline and experimental (postmaneuver) and baseline and posttest tracings for seven measures: tympanogram peak pressure, peak acoustic admittance, static acoustic admittance, negative gradient, positive gradient, and negative and positive acoustic-admittance values at ±400 daPa. The results indicated a statistically significant difference only in peak pressure for baseline and experimental tympanograms. Peak-pressure shifts were most pronounced for the Valsalva and Toynbee procedures. The small pressure shifts characteristic of the Inflation and Deflation procedures coupled with the potential for instrumental error severely limit the use of these procedures as means of obtaining reliable indices of tubal function.

Objective The purpose of this study was to compare the effects of Veau-Wardill-Kilner (VWK) two-flap palatoplasty and Furlow double-opposing Z-plasty operations on eustachian tube (ET) opening in patients with cleft palate (CP). Design Twenty-six patients underwent CP repair between 1993 and 1997. VWK and Furlow operations were used in 13 patients each. All patients were examined by the otorhinolaryngologist before and after the operations; mean follow-up time was 27.3 months. Secretory otitis media (SOM), as identified by tympanograms, was the comparison criterion used. Results The prevalence of SOM was 69% (n = 18) in all CP patients pre-operatively. Among those with preoperative SOM, we did not find any statistically significant difference in the frequency of postoperative SOM between the two techniques. Conclusion This study suggests that there is no difference in postoperative ET function between patients undergoing either VWK or Furlow operations, in spite of the differences in muscle positioning in these operations. We discuss the implications of this finding in relation to surgical anatomy and histology of the soft palate muscles.
