0.05) except for 8 kHz. Air conduction thresholds were basically normal in children's simple type CSOM, whereas hearing loss during intermediate frequency and high frequency in adults with osteitis and cholesteatoma type was more severe than that in children.Conclusion Hearing-loss in children's CSOM was the same as adult patients, although course of disease was not long in children. Inner ear was not or mildly impaired in children's CSOM.

Objective To evaluate the application of the inlay butterfly cartilage graft technique in myringoplasty.Methods Thirty--eight ears in 38 patients (experiment group) with dry central drum perforations were treated with inlay butterfly cartilage myringoplasty,and 46 ears in 46 patients with underlay temporalis fascia myringoplasty (control group).Results After a mean follow-up of 6 months,the healing rate did not differ between two groups (92.1% in experiment group,91.3% in control group,P＞ 0.05).Average pure-tone hearing threshold improved than 10 dB and closure of the air-bone gap (ABG) within 10 dB were not different (P ＞ 0.05).The cured patients were followed up for 12-38 months,there was no ear perforation of drum in experiment group,but 4 ears in control group.Condusion Inlay butterfly cartilage myringoplasty is the reliable and ideal method for tzeating dry central drum pedoration with high success rate.

Objective:To evaluate the vestibular function of motion sickness. Method:VNG, which tests the vestibular function of horizontal semicircular canal,and CPT, which tests vestibulospinal reflex and judge proprio-ceptive,visual and vestibular status, were performed in 30 motion sickness pations and 20 healthy volunteers(control group). Graybiel score was recorded at the same time. Result:Two groups' Graybiel score (12. 67±11. 78 vs 2. 10±6. 23;rank test P<0. 05),caloric test labyrinth value [(19. 02±8. 59)°/s vs (13. 58±5. 25)°/s ;t test P< 0. 05],caloric test labyrinth value of three patients in motion sickness group exceeded 75°/s. In computerized pos-tourgrphy testing(CPT) , motion sickness patients were central type(66. 7%) and disperse type(23.3%);all of contral group were central type. There was statistical significance in two groups' CTP area, and motion sickness group was obviously higher than control group. While stimulating vestibulum in CPT, there was abnormality (35%-50%)in motion sickness group and none in contral group. Generally evaluating CPT,there was only 2 pro-prioceptive hypofunction,3 visual hypofunction, and no vestibular hypofunction, but none hypofunction in contral group. Conclusions Motion sickness patients have high vestibular susceptible, some with vestibular hyperfunction. In posturography,a large number of motion sickness patients are central type but no vestibular hypofunction, but it is hard to keep balance when stimulating vestibulum.

OBJECTIVE: This research focuses on the psychologic status of children patients with congenital malformation of external and middle ear by Achenbach's Child Behavior Checklist (CBCL) in order to explore the degree of the influence. METHOD: The 66 patients of 4-16 years old were assessed psychologic status with CBCL filled in by their parents according to their performance in half a year. Then calculated the detection rate of behav ioral disorders of these patients. Collected all patients' general information and Marx's grade of malformed ears. Then analyzed the relationship between the detection rate and these factors. RESULT: The detection rate of behavioral disorders of 4-16 years old patients, 21.21%, which is higher than that of Chinese norm. The Marx's grade and parents' mental stress relate with the behavioral disorders. In Logistic regression analysis, the value of Cox & Snell coefficient of the regression model is 0. 153. The detection rate of behavioral disorders in grade III patients (36.4%) is greater than that of grade II (4.3%), P = 0.004. CONCLUSION Congenital malformation of external and middle ear has an absolute influence on the patients' psychologic status, but its effect is only about 15% parts of the multitudinous influential factors. And grade III patients carry a high-risk for behavioral disorders.

Objective Following up with otoscopy after the middle ear surgery in order to understand the prognosis and recurrence of the surgical cavity. Methods Four hundred and eighty-three ears after middle ear surgery were followed up with otoscopy to understand the situation of its dry ear, surgical cavity lesions as well as whether there was recurrence. Among 483 ears with middle ear surgery, 172 ears were performed with tympanoplasty, 211 ears with tympanoplasty plus modified mastoidectomy, 26 ears with up wall mastoidectomy plus tympanoplasty, 15 ears with radical mastoidectomy, 59 ears with mastoid surgical cavity repair. Results By otoscopy 12 ears were found with secondary tympanic membrane perforation, 9 ears with tympanic membrane perforation without healing, 36 ears with granulation in tympanic membrane or mastoid, 23 ears with recurrent cholesteatoma, 11 ears with middle ear effusion, 5 ears with canal stenosis, 16 ears with fungus infections in surgical cavity, 2 ears with prolapse of artificial auditory ossicles, 3 ears with necrosis of mastoid cavity flap. The time of dry ear after the surgery in open mastoidectomy was (2.1 ± 0.4) months. Conclusion Following up regularly with otoscopy after middle ear surgery is benefit to the clearance of residual disease, preventing recurrence and promoting early dry ear.

To investigate the clinical features of laryngeal papilloma in children.Method:In a group of 62 patients with laryngeal papilloma in children,the tumors of 28 patients were cut under the direct laryngoscope,34 patients were treated with laryngeal micro-laser operation.Result:The post-operation followup ranged from 2 to 5 years,the cure rate of 2 years was 51.61%.Conclusion:The clinical features of this disease include rapid development,a large lesion,and it is often found in the infraglottic cavity.Furthermore,we believe that in order to eliminate the tumors more accurately and decrease recurrence,microlaser surgery and the use of interferon is very necessary.

Objective To explore the therapeutic efficacy and complications of endoscope-assisted lateral skull base surgery. Methods Assisted by hard-tube ear endoscope, 11 patients with acoustic neuroma were operated via labyrinthine approach and retrosigmoid approach, and 5 patients with petrous apex cholesteatoma were operated via middle cranial fossa approach and mastoid-middle cranial fessa approach. Results Among 11 patients with acoustic neuroma, total removal was achieved in 9 cases (81.8%), subtotal in 2 cases (18.2%). Facial nerves and cochlear nerves were preserved completely during operation. After operation there was no facial paralysis in 9 cases (81.8%), mild peripheral facial paralysis in 2 cases (18.2%), the same hearing level as that of preoperation in 2 patients (18.2%), hearing impairment in different degrees in 9 cases (81.8%), among which moderate sensorinural hearing loss in 1 patient (9.1%), moderate to severe in 2 patients (18.2%), severe in 3 patients (27.3%), profound in 3 patients (27.3%). Among 5 patients with petrous apex cholesteatoma, total removal was achieved in all cases. After operation, preoperative facial paralysis in 3 patients disappeared within 9 months, and moderate to severe conduction deafness appeared in 2 patients. Conclusions The application of ear endoscope in lateral skull base surgery can improve the total removal of lesions and the salvage rate of vessels and nerves. However, its disadvantages make it only be an assistant method for micresurgery.

[ABSTRACT]OBJECTIVETo evaluate the short-term efficacy of Eustachian tube balloon dilation (ETBD) in the treatment of symptomatic Eustachian tube dysfunction (SETD) by subjective and objective analysis.METHODS Forty patients who underwent ETBD were included. Subjects’ inclusion criteria were as followed: symptoms of ETD (aural fullness predominantly, with or without otalgia, muffle hearing and tinnitus), normal tympanic membrane, type A or C tympanograms, and without a history of any middle ear diseases. Main outcomes including subjective improvement, otoscopy, pure-tone audiometry, impedance audiometry, R-value in tubomanometry (TMM) and Eustachian Tube Score (ETS) were assessed 1 week and 6 months postoperatively.RESULTSAll cases were dilated successfully. A significant effect of treatment was documented when measuring subjective improvement, impedance audiometry, R-value in TMM and ETS 1 week and 6 month postoperatively. Subjective symptoms were not relieved only in one patient. The overall success rate for all patients was 98%.CONCLUSIONETBD can provide short-term benefits to those who are diagnosed with SETD and refractory to medical management. SETD might be an optimal indication for ETBD in the treatment of ETD.

OBJECTIVE: To investigate the risk factor,type and characteristic nystagmus of the otolith abnormal migration during diagnosis and treatment for posterior semicircular canal benign paroxysmal positional vertigo (PSC-BPPV). The therapy and prevention is also discussed. METHOD: Four hundred and seventy-nine patients with PSC-BPPV were treated by Epley's canalith repositioning procedures(CRP) from March 2009 to March 2012. We observed otolith abnormal migration complicating during diagnosis and treatment. According the type of otolith abnormal migration, the additional repositioning maneuver was performed. RESULT: The rate of complication was 8. 1%(39/479), with canal conversion in 5.4%(26/479) and primarily canal reentry in 2.7%(13/479). The rate of incidence of conversion to horizontal canal conversion and anterior canal were 4. 8%(23/479)and 0. 6%(3/479) respectively. All the patient was cured in follow up. The risk factors were unappropriated head movement during or after CRP, including another Dix-Hallpike were performed immediately. CONCLUSION To prevent the complications,the pathognostic positioning sequence and angle of head rotation are commenced during CRP. Appropriate short time postural restrictions post-treatment is necessary. Careful observation of nystagrnus variation is crucial to determine the otolith abnormal migration.
