ABSTRACT
Objective To investigate the multi-slice spiral CT characteristics of inner ear in child sensorineural deafness and its application analysis.Methods A total of 41 children patients(82 ears) with sensory deafness treated in this hospital from March 5,2016 to March 5,2017 were selected.The screening test was adopted to observe the accuracy rate of multi-slice spiral CT and monolayer spiral CT for diagnosing the inner ear malformation.The inner ear characteristics in child sensorineural deafness revealed by multi-slice spiral CT were observed.Results The sensitivity of multi-slice spiral CT for diagnosing child sensorineural deafness was 87.72 ％,the specificity was 80.00 ％ and the Gordon index was 0.68;the diagnostic sensitivity and specificity in the single-slice spiral CT were 59.65 ％ and 68.00 ％ respectively,the Gordon index 0.28;the sensitivity of the multi-slice spiral CT group was significantly higher than that of the single-slice spiral CT group,the difference was statistically significant(x2 =4.31,P＜ 0.05).The multi-slice spiral CT results showed 36 cases(63.2 ％) of vestibular aqueduct abnormalities,which were significantly higher than 16 cases (28.1％) of cochlear deformity,vestibular deformity in 18 cases (31.6 ％),semicircular canal deformity in 22 cases(38.6％) and inner ear canal deformity in 16 cases(28.1 ％),the differences were statistically significant(x2 =21.11,P＜0.05).Coclusion Multi-slice spiral CT can more completely display the inner ear deformity structure to provide more comprehensive and accurate diagnostic information.
ABSTRACT
Objective To discuss the tympanic membrane puncture or tympanostomy tube under endotoscope combined with adenoidectomy under nasal endoscopy on the influence of invalid conservative treatment of pediatric secretory otitis media.Methods A total of 112 cases of secretory otitis media with invalid conservative treatment were selected in the department of otorhinolaryngology of children′s hospital of Nanjing Medical University from July 2013 to August 2015.They were divided into three groups,the group A of 38 cases(68 ears)underwent transnasal endoscopic pure adenoidectomy;the group B of 37 cases(60 ears)underwent transnasal endoscopic adenoidectomy combined with tympanocentesis;the group C of 37 cases(59 ears)underwent tympanostomy tube insertion.The clinical treatment effect,the period of middle ear effusion,postoperative recurrence and complication were observed and compared.Results The total effective rate of the 3 groups was improved after 3 months(P<0.05);the total effective rate in group B and group C at one week and 3 months after operation were higher than those of group A(P<0.05);and the total effective rate in group C at 3 months after operation was significantly higher than that of group B(P<0.05).The level of auditory brainstem evoked potential(ABR)and the latency of ABR wave Ⅰ latency were decreased at 1 year after operation(P<0.05);the ABR changes in group B and group C at 1 week and 1 year after operation were lower than those in group A(P<0.05).The incidence of recurrence rate and the period of middle ear effusion in group C were lower than those in group A and B(P<0.05).The incidence of complication of group A was lower than those of group B and group C(P<0.05).Conclusion Using tympanostomy tube combined with adenoidectomy under endoscope can improve the children with hearing,which not only can shorten the time of the middle ear effusion,but also effectively reduce the recurrence rate.
ABSTRACT
OBJECTIVE@#To investigate incidents and clinical features of auditory neuropathy in Nanjing deaf school students.@*METHOD@#Three hundred and fifty-eight deaf students in the school accepted the first examination including otoscopic examination, tympanometry and transiently evoked otoacoustic emissions (TEOAE) screening. Detailed audiological and vestibular evaluations including pure-tone audiometry, immittance audiometry and acoustic reflex measures, transiently evoked otoacoustic emissions (TEOAE), distortion product otoacoustic emissions (DPOAE), auditory brain stem response (ABR), electronystagmography (ENG) and vestibular evoked myogenic potential (VEMP) were given to whom had positive TEOAE screening.@*RESULT@#Three hundred and twenty-three students entered the program of screening for auditory neuropathy. One student had positive TEOAE in single ear while the other two had positive TEOAE in both ears. In the screening stage,there were strong evidences in these three students with auditory neuropathy in the detailed audiological procedures.@*CONCLUSION@#Auditory neuropathy, which can also be found in deaf schools, is not as rare as we thought before. Early identification and intervention may help those children to avoid entering the deaf school and to return to normal society.
