Abstract:
BACKGROUND AND OBJECTIVES:The presence of encapsulated nerve corpuscles that is involved in regulating middle ear pressure has been noticed in previous studies. Based on those findings, how the sensory receptors in the tympanic membrane and tubal function are related was tested in the present study. MATERIALS AND METHODS: Tubal function was tested by 9 step test using Grason-Stadler institute(GSI) Middle ear analyzer II Eustachian tube function(ETF) test mode. Tubal function was recorded as compliance of the tympanic membrane on an otoadmittance meter. To anesthetize the sensory receptors in the tympanic membrane, iontophoresis was applied to the twenty right ears of the twenty subjects. RESULTS: Peak pressure difference in the middle ear was reduced after the tympanic membrane (TM) anesthesia, which indicates that the tubal function has decreased due to pressure change in the sensory receptors in the tympanic membrane. CONCLUSION: The findings of the present study suggest that there may be a neural connection between the sensory receptors in the tympanic membrane and the tubal muscle, as the eustachian tube function changed following the TM anesthesia.
