ABSTRACT
Objective To study the influence of cochlear implantation on residual hearing in children .Methods Behavioral audiometry were performed pre -implant and 3~21 months post -implant on thirty -four cochlear implant recipients with severe to profound hearing loss .According to follow -up time ,they were divided into 2 groups which were Group A(3~12 months ,21 cases) and Group B(≥13 months ,13 cases) .The thresholds at 250 Hz ,500 Hz ,1 000 Hz and 2 000 Hz were analyzed .Results There were 25 out of 34 patients (73 .53% ) had partial residual hearing after cochlear implantation .Comparing to the hearing loss pre -operation and post -operation , which were most obvious at 500 Hz ,followed by 250 Hz ,1 000 Hz ,2 000 Hz (P<0 .05) ,and there were significant different among different frequencies .There was significant difference at different frequencies at hearing loss thresh-olds only in Group A .But there was no significant difference in Group B .With the prolonged time after the cochlear implantation ,residual hearing at all frequencies showed a trend of recovery .Conclusion The residual hearing could be partial preserved after cochlear implant in pediatric patients with severe to profound hearing impaired ,the residu-al hearing at lower frequencies (250 Hz ,500 Hz) were less affected than those at higher frequencies .With the pro-longed time after the cochlear implantation ,the residual hearing showed a certain degree of recovery .
ABSTRACT
Objective To know the position and shape of implanted electrode array with plain X-ray after cochlear implantation. Methods According to the Cochlear View developed by Xu plain X-ray was taken postoperatively to obtain the best view of electrode array. Results The Medical imaging of plain X- ray taken before switching on or following the concerning of the performance could assist in the detection of electrode arrays in improper position, partial insertion or bending inside the cochlea. It helped audiologists to make decisions to switch off affected electrodes for the optimization of the program, if functioning electrodes were insufficient and recipients failed. Conclusion It is recommended to conduct post-operative X-ray examination routinely for cochlear implant recipients. Audiologists should be able to use medical imaging to identify the position of intra-cochlear electrodes and apply the information to guide the mapping work.
ABSTRACT
OBJECTIVE@#To explore the value of laryngeal functional reconstruction with pedunculated musculocutaneous flap of platysma after partial laryngectomy.@*METHOD@#Fifty-four cases with glottic carcinoma were operated by partial or enlarged partial laryngectomy, and reconstructed laryngeal function with pedunculated musculocutaneous flap of platysma.@*RESULT@#All the cases regained the swallow, vocalization and breath. The rate of extubation was 100%, and the 5-year survival rate was 92.59%.@*CONCLUSION@#Application of pedunculated musculocutaneous flap of platysma to reconstruct laryngeal function is one of the effective method after partial laryngectomy.

OBJECTIVE To compare the results of plasma scalpel assisted uvulopalatopharyngoplasty(UP PP) under local anesthesia(PS)with radiofrequency volumetric tissue reduction(RF)in the treatment of obstructive sleep apnea/hypopnea syndrome (OSAHS). METHODS Sixty-nine and 79 patients were treated with PS and RF respectively. They were followed-up for 6 and 12 months after operation and the outcomes of the 2 surgical methods were compared. RESULTS The improvement rates at 6 months after PS and RF were 85.5 % and 83.5 % respectively. There was no significant difference between the 2 methods. The improvement rates at 12 months after PS and RF were 78.3 % and 49.3 % respectively. The difference was significant. No major complication was found. CONCLUSION The long-term outcome of PS is better than that of RF. PS surgery may be comparable with surgery under general anesthesia in some special cases.
ABSTRACT
BACKGROUND: The mechanism of spasmodic dysphonia(SD) is still unclear and lacks of confirmed diagnostic standards. Limited reports on the treatment mainly focused on botulinum toxin infiltration; recurrent laryngeal nerve section, and voice training, amongst which voice training has been considered as one of the ideal complementary therapeutic means for SD because of less side effects and complications.OBJECTIVE: To investigate the significance of voice training in the treatment of SD and provide a method for the clinical treatment.DESIGN: Clinical case analysis and retrospective study based on patients.SETTING: Department of otolaryngology and cerebral surgery in a university hospital.PARTICIPANTS: Thirty-six confirmed SD patients in Wuhan College affiliated Renmin Hospital from February 1985 to December 2002.METHODS: Psychological consultation combined with breathing and voice training was adopted to make patients breathe freely and coordinately, with breath pattern changed from deep chest breathing and reversal breathing to normal chest-abdominal combined breathing, which helped decreasing larynx muscle straining. All patients were followed up for one to two years and their therapeutic effects were assessed by normal phonation, improvement, and ineffectiveness.MAIN OUTCOME MEASURES: Assessment of therapeutic effects.RESULTS: All 36 SD patients achieved satisfactory outcomes after voice training, with SD completely recovered in 30 cases and obviously improved in 6 cases.CONCLUSION: Psychological consultation combined with voice training is an ideal approach for the rehabilitation of SD.
ABSTRACT
Objective To explore the effect of vocal rehabilitation training on patients with spasmodic dys-phonia. Methods Thirty-six patients with spasmodic dysphonia were recruited, and psychotherapy, acupuncture,respiratory and vocal training were performed according to the patients condition to improve the coordination of the vo-cal organs. Interventions were also employed to convert the patients reverse or high locational pattern of respiration in-to the normal associated chest and abdomen respiration, so as to reduce the tone of the laryngeal muscle. ResultsSatisfactory effects were achieved by the rehabilitation training. 30 out of 36 cases recovered and the other 6 cases im-proved. Conclusion It indicated that the comprehensive vocal rehabilitation should be adopted for the treatment ofpatients with spasmodic dysphonia.
ABSTRACT
ObjectiveTo search for the optimum external masking time and tonal models for patients with tinnitus.MethodsTwenty-seven patients with cochlear tinnitus were selected respectively from three different out-patients departments and divided into three groups. Nine patients in every group were treated with different masking parameters according to factorial design which had three masking noises, i.e. narrow band noise (NBN), wide band noise (WBN), speech noise (SN),and three masking time ranges, i.e. 15,30,45 minutes. The results before and after treatment were compared and analysed with analysis of variance (ANOVA). ResultsThe treatment effect when masking for 15 minutes was worse than that for 30,45 minutes, but there was no difference between 30 and 45 minutes. The NBN had the best effect when tinnitus signal was single, the WBN was effective for tinnitus with multiple sounds. ConclusionNBN or WBN masking for 30 minutes showed better therapeutic effect.
ABSTRACT
Nine patients with tinnitus were treated with tinnitus retraining therapy( TRT) between August and November, 1997. The components of TRT included(1)correct counselling, (2)use of appropriate hearing aid, (3)mask with a low level sound, (4)use of relaxation technique. 7 cases demonstrated encouraging results of treatment. This provides a new method for treatment of tinnitus.
