Abstract: Objective To investigate the occurrence of eustachian tube dysfunctionchronic in adult chronic suppurative otitis media to provide reference for the clinical diagnosis and treatment. Methods Active opening function, passive opening function and incidence of eustachian tube dysfunction were detected by inflation-deflation balance test combined with sonotubometry and tube-tympano aero dynamic graphy in 241 patients (266 ears) with chronic suppurative otitis media (group A) and 53 patients (60 ears) with traumatic tympanic membrane perforation (group B). Results The average opening pressure of eustachian tube in group A (155.62±33.71daPa) was higher obviously than that in group B(67.39±16.57daPa) (P<0.05). In inflation balance test, external auditory canal pressure of 207 ears (77.82%) in group A could be restored to less than 50daPa, in deflation test, 50 ears (18.80%) in group A couldn,t be returned to less than 100daPa, while the external auditory canal pressure in group B all returned to less than 50daPa (100%), the difference had statistical significance between the two groups (P<0.05). There were 47ears (17.67%) could not complete Valsalva action successfully in group A, but all completed successfully in group B. The difference in the ratio of ABG>30dB in the two groups was not obviously. Maximum tympanic pressure difference in group A (17.28 ±.33daPa) was greater than group B (14.53 ± 4.06daPa), group A had poorer eustachian tube active and passive opening functions than group B (P<0.05). Comprehensive analysis showed that 95 ears were eustachian tube obstruction, 76 ears were eustachian tube incomplete lack in group A, that was to say, the incidence of ETDF was 64.29 (171/266). In Group B, 2 ears were eustachian tube incomplete lack, the others were normal, the incidence of ETDF was 3.33%(2/60), the difference had statistical significance between the two groups (P<0.05). In addition, the chief eustachian tube dysfunction in CSOM patients was obstruction, most CSOM patients with cholesteatoma or caries revealed eustachian tube dysfunction. Tympanic membrane perforation also had effect on eustachian tube dysfunction in CSOM patients. Conclusions Eustachian tube dysfunction had high incidence in CSOM patients, and eustachian tube function related to CSOM type and tympanic membrane perforation.
