Abstract:
OBJECTIVE:To investigate the clinical value of negative pressure tympanograms for diagnosis of middle ear effusion in adults.
METHOD:GSI-Tympstar II Middle Ear Analyzer of America was used to test tympanogram peak pressure (TPP); tympanogram width (TW); middle ear resonant frequency and stapedius muscle reflex for sceptical secretory otitis media (SOM) adult patients. Patients (207 ears) with C type tympanograms accepted tympanocentesis after tests. According to middle ear effusion quantity, 207 ears have been divided to three groups: non-effusion group (123 ears), small-effusion group (45 ears) and mickle-effusion group (39 ears). Acoustic immittance and ipsilateral stapedius muscle reflex were statistically analysed.
RESULT:About TPP and resonant frequency, non-effusion group and small-effusion group have statistical difference (P < 0.05); non-effusion group and mickle-effusion group have significant statistics different (P < 0.01). About TW, non-effusion group have significant difference from mickle-effusion group (P < 0.01). There was statistical difference on ipsilateral stapedius muscle reflex (P < 0.01) among three groups.
CONCLUSION:Negative pressure tympanograms has diagnostic value for middle ear effusion combined to TPP, TW, middle ear resonant frequency and ipsilateral stapedius muscle reflex.
