Postpalatoplasty Eustachian tube function in young children with cleft palate.

OBJECTIVE

To characterize Eustachian tube function using the forced response test in young children with cleft palate with or without cleft lip after palatoplasty with tympanostomy tubes inserted prepalatoplasty and compare these results with those of a 1986 study that evaluated a similar population using identical methods.

SETTING

Outpatient research clinic.

PATIENTS/PARTICIPANTS: A total of 34 children with cleft palate were tested at an average age of 18.6 ± 4.0 months. MAIN OUTCOME MEASUREs: Passive and active measures for the forced response test.

RESULTS

Of the sample, 13 ears could not be tested, and tests on 24 ears were incomplete. The forced response test showed that the passive Eustachian tube function parameters were similar to those of normal adults and children. The percentage of ears that showed tubal dilation with swallowing was 60%. The active resistance and dilatory efficiency were similar to those of a normal adult population.

CONCLUSIONS

A 1986 study of Eustachian tube function in postpalatoplasty subjects with cleft palate (37 ears) aged 15 to 26 months documented Eustachian tube dilation with swallowing in 84% of the ears. In the present study, which focused on a similar population, the frequency of tubal dilation was 60%. Nonetheless, both frequencies are significantly greater than the dilation frequency of 27% reported for 56 ears of subjects with cleft palate tested between 3 months and 18 years with tympanostomy tubes inserted for persistent otitis media with effusion. This suggests that dilation during the forced response test may be a prognostic marker for those children with cleft palate who will resolve their ear disease at an early age.
