The Analysis of High Frequency Sensorineural Hearing Loss Caused by Piston Technique of Stapes Surgery in Patient with Otosclerosis / 听力学及言语疾病杂志

Objective To examine the causes of high frequency sensorineural hearing loss caused by piston technique of stapes surgery.Methods The retrospective analysis involved in thirty cases(49 ears)with stapedectomy from February 2004 to 2009 at our hospital.Pure tone audiometry was performed for each patient who underwent stapedectomy both during the two days preoperation and 1,3,6 months postoperation.Results One month after operation at 8000 Hz,the air conduction hearing threshold was 8 dB less than that before,4 000 Hz average bone conduction hearing threshold was 10 dB less than that before(P < 0.01).The average high-frequency hearingthreshold of ≥40 years old group was noticeably declined than that of 40 years old group(P < 0.01).There was no association between the tinnitus and high frequency hearing loss.(P >0.05).Conclusion Transient high-frequency sensorineural hearing losses occurred to most patients under going stapedectomy,but showed significant improvement,3 months after the surgery.The average high-frequency hearing threshold of ≥40 years old group was seriously declined than that of 40 years old group.

Analysis and comparison of the masking and TRT for patients with subjective tinnitus / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To compare the effect of tinnitus masking and tinnitus retraining therapy (TRT) in patients with subjective tinnitus, and to analyze the effect of TRT within the positive or negative group of tinnitus masking test.@*METHOD@#The 217 patients from January, 2006 to April, 2008 in our hospital, were performed with the determination of tinnitus including pitch matching, intensity matching, Feldmann masking curve and residual inhibition test with Tinni Test. Of which 143 cases were positive and 74 were negative in tinnitus masking. The follow-up was 6 months and 10 cases were lost. 207 patients were divided into two groups for prospective study: 69 cases in tinnitus masking group and 138 cases in TRT group, The curative effect was evaluated according to tinnitus handicap inventory (THI) and Subjective Visual Tinnitus Scale (SVTS).@*RESULT@#Both masking treatment and TRT were effective for cases with tinnitus, there was significant difference of the score of THI and SVTS of tinnitus between pretherapy and posttherapy (P < 0.01). TRT therapy was more effective than masking therapy, there was significant difference of the THI score between TRT and masking group,but there was no significant difference of of the SVTS between them. TRT therapy was suitable for the patients with both positive effect and negative effect of masking test, and there was no significant difference between them.@*CONCLUSION@#Both TRT and masking therapy are the most important therapy for tinnitus patients, but TRT is much more effective than masking therapy in some aspects.

Characteristic of nystagmus and treatment of horizontal semicircular canal benign paroxysmal positional vertigo / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the characteristic of nystagmus and treatment of horizontal semicircular canal benign paroxysmal positional vertigo (HSC-BPPV).@*METHOD@#The positioning nystagmic features in 43 patients with HSC-BPPV treated between April 2004 and October 2006 were recorded and analyzed with video nystagmography. After the subtype and the effect side were determined, the appropriate repositioning maneuvers were chosen.@*RESULT@#(1) Geotropic nystagmus was recorded in 27 cases, of whom 19 cases were treated with barbecue maneuver and/or combined forced prolonged position maneuver, while the others were treated with Asprella's maneuver. (2) Apogeotropic nystagmus was recorded in 16 cases with two types, one of which could turn into geotropic nystagmus with Gufoni's maneuver or spontaneously (in 12 cases), the other type could not (in 4 cases) transform accepted barbecue maneuver and/or combined forced prolonged position maneuver. The total improvement rate was 72.1% after 1 week and 81.4% 3 months later respectively.@*CONCLUSION@#The otolith position and the pathogenesis could be distinguished according to the nystagmic characteristics and type of HSC-BPPV. It was necessary to apply the appropriate repositioning maneuvers to treat HSC-BPPV.

Influence of childhood obstructive sleep apnea-hypopnea syndrome on hearing / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the influence of hypoxemia on the hearing of children with childhood obstructive sleep apnea-hypopnea syndrome (OSAHS).@*METHOD@#Auditory brainstem response (ABR) and distortion-product otoacoustic emission (DPOAE) was recorded in 68 ears and 60 ears respectively of children suffering from OSAHS with "A" tympanogram. Meanwhile, ABR and DPOAE was also recorded in 30 controls of children with "A" tympanogram.@*RESULT@#There was no statistical difference between the mild OSAHS group and the control group in the latency of wave I, III and V, the interval between wave I and III, III and V, I and V. There was significant difference between the moderate and severe OSAHS group and the control group in the delayed latency of wave I. There was significant difference between the mild OSAHS group and the control group in the amplitudes of DPOAE at 8 kHz. There was significant difference between the moderate and severe OSAHS group and the control group in the amplitudes of DPOAE at 6 kHz and 8 kHz.@*CONCLUSION@#Cochlear function was affected when AHI > or = 10/h. ABR and DPOAE could be used to detect the early damagement of auditory function in childhood OSAHS.

Relationship between childhood obstructive sleep apnea-hypopnea syndrome and tympanogram / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the correlation between childhood obstructive sleep apnea-hypopnea syndrome and tympanogram.@*METHOD@#A prospective clinical study was carried out. Polysomnography and tympanogram were analyzed in 72 cases.@*RESULT@#Among the 144 ears 37 ears had type C or B tympanogram. There was no correlation between tympanogram and LSaO2. It was found correlation between tympanogram and AHI (P < 0.05).@*CONCLUSION@#Hypoxemia may affect middle-ear function. It was necessary to do the examination of acoustic impedance routinely in children with moderate and severe OSAHS.

Clinical analysis of otitis media with effusion in adults and children / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the different and common features between adults and children with otitis media with effusion (OME) on course of disease, clinical characteristics and audiometric changes.@*METHOD@#Pure tone audiometry, tympanogram and clinical information were analyzed and compared between 34 cases of adults and 42 cases of children with OME.@*RESULT@#The course of disease was relatively short in children. The adenoid vegetation inflammation was more frequently found in children, while the OME occurred more often in adults. The air conduction and bone conduction threshold increased both in children and adults, particularly at high frequencies of 2 and 4 kHz. The bone conduction threshold at 4 kHz in adults was significantly higher than that in children (P < 0.05). In the cases with C type tympanogram, the negative pressure in adults was even lower than that in children (P < 0.05).@*CONCLUSION@#The OME in children is often relatively shorter in course of disease, which is mainly caused by adenoid vegetation. Sensorineural deafness can occur both in children and adults, especially at high frequencies. OME in children is less severe, however, it may lead to negative effects in learning and cognition, which should be diagnosed and managed in time.

Audiological Analysis in Children and Adults with Chronic Suppurative Otitis Media / 听力学及言语疾病杂志

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.

Infection of Respiratiory Viruses and Secretony Otitis Media / 听力学及言语疾病杂志

Objective To discuss the relationship between the infection of respiratory viruses and secretory otitis media(SOM). Methods The alkaline phosphatase anti-alkaline phosphatase(APAAP) bridged rapid diagnosis was used to detect the antigens of the common respiratory viruses in middle ear effusions(MEES). Results One or more kinds of antigens of respiratory viruses were detected in 73.9% MEES. Six kinds of antigens were detected in three patients' MEES at the same time. There were significant differences positive rates of the antigens of respiratory viruses in MEES with or without a cold history(P
