Title: The Impact of Radiotherapy on Middle Ear Pressure in Nasopharyngeal Carcinoma Patients
Abstract: To study the impact of radiotherapy on middle ear pressure in nasopharyngeal carcinoma(NPC)patients.First diagnostic NPC patients(n=60)with normal hearing in language zone and A type graph of tympanic pressure before radiotherapy were randomly divided into two groups.The first group received local treatment of nasal cavity and nasopharynx radiotherapy.The second group received radiotherapy alone.Tympanic pressures of the first and the second group was measured at the end of radiotherapy.At the end of radiotherapy,there was significant difference in the measurement of tympanic pressure(z=-5.159,P0.005)between the first group and the second group.[Conclusions]More negative pressure values of the middle ear was mainly associated with organic obstruction of eustachian tubes at the end of radiotherapy in nasopharyngeal carcinoma patients.Local treatments of nasal cavity and nasopharynx have a good effect.
