ABSTRACT
OBJECTIVE: To study the method on comprehensive evaluation of the middle ear function in children with secretory otitis media (SOM) after tympanotomy tube insertion. METHOD: Ear canal volume (ECV), pure tone audiometry and distortion product otoacoustic emission(DPOAE) were carried out in 31 children(43 ears) with SOM before and 1 month after tube insertion,in the meantime Eustachian tube function was recorded. The tympanotomy tube was observed under microscope. RESULT: After one month of tube insertion, the hearing level was improved in 39 ears with an ECV > 2.0 ml. In addition,the detection rate and amplitude of DPOAE were significantly increased in these 39 ears. No case of the function of Eustachian tube was complete recovered. CONCLUSION: ECV, pure tone audiometry, DPOAE and inflation-deflation test are significantly clinical worth for comprehensive evaluation of the middle ear function in children with SOM after tympanotomy tube insertion.

OBJECTIVE: To investigate the objective methods for tinnitus exploration by analysing the cochlear activity in tinnitus patients with normal hearing. METHOD: The 50 cases (50 ears) of unilateral tinnitus with normal hearing (the plastic group 1), 24 cases (46 ears) of bilateral tinnitus with normal hearing(the plastic group 2) and the 34 persons (68 ears) of normal hearing without tinnitus (control group) were measured by evoked otoacoustic emissions (TEOAE and DPOAE). All the tinnitus patients were also tested by the subjective tinnitus frequency and analysed with appropriate characteristic in TEOAE and DPOAE audiogram. RESULT: (1) The passing rate of TEOAE was 64.0% in the tinnitus group 1, 91.3% in the group 2, and 100% in the control group (group 1 P < 0.01, group 2 P >0.05 ). (2) The passing rate of DPOAE was 100% in three groups. But comparing to the control group, the amplitudes of DPOAE at the limited frequency ranges (3.125 kHz and 8.837 kHz) of the tinnitus group 1 was significant decreased ( P <0.05). (3) The subjective tinnitus frequencies were 0.25 approximately 8.00 kHz. The decreases in amplitudes and absent within the tinnitus frequencies were observed in TEOAE and DPOAE audiogram. CONCLUSION: Some patients of normal hearing with tinnitus have had early harmness of outer hair cell in cochlear. Evoked otoacoustic emissions is one of worthy methods to evaluated objectively the tinnitus. TEOAE is more susceptible to harmness in cochlear than DPOAE. DPOAE is superior to the analysis of tinnitus frequencies.

OBJECTIVE: To summarize the symptoms, various diagnostic procedures, and therapy of extraluminal foreign body originated from pharynx and esophagus (EFBOPE). METHOD: Twenty-four patients with EFBOPE were retrospectively reviewed. RESULT: Twenty-two cases were removed surgically, 1 case was spontaneous expulsion, 1 case died. CONCLUSION: EFBOPE is seldom seen in the clinical, diagnosis of EFBOPE should be considered whenever haematemesis or haemorrhage, inflammation or abscess in parapharyngeal space outside of pharynx and esophagus are presented after ingesting foreign body. Radiography and computed tomography are main diagnostic tools. Surgical treatment is the only effective method for EFBOPE and must be performed in time.
