Analyses of chronic otitis media with intact tympanic membrane concurrent with intracranial complication / 中华耳鼻咽喉头颈外科杂志

<p><b>OBJECTIVE</b>To investigate the clinical and imaging characteristics of chronic otitis media with intact tympanic membrane.</p><p><b>METHOD</b>Ten patients were retrospective studied in the department of otorhinolaryngology of Guangdong general hospital from December 2006 to January 2015. The clinical characteristics of their manifestations, audiology and imaging examinations were analyzed.</p><p><b>RESULTS</b>All the cases could be divided into two groups: the intracranial complication group who was primarily diagnosed as intracranial complications, and the hearing loss group who primarily complained of hearing loss. Five cases belonged to the first group, which include 1 cerebellar abscess, 3 meningitis and 1 meningoencephalitis, 2 of them were profound hearing loss, 2 were mixed hearing loss, and 1 was normal hearing. The other 5 cases belonged to the hearing loss group, 3 were mixed deafness, 2 were conductive deafness. All the case showed positive high-resolution computed tomography (HRCT) features. In the first group, four cases showed the soft tissue shadow in tympanic antrum/superior tympanic pouch and 1 case showed a wide damage of skull base, in addition to intracranial complications. In the second group, five cases showed soft tissue imaging in tympanic antrum/superior tympanic pouch. Pathology showed that 2 cases were cholesterol granuloma(one was in the first group and the other was in the second group), 4 were intracranial inflammatory(the first group) and 4 were cholesteatoma(the seond group).</p><p><b>CONCLUSIONS</b>In chronic otitis media with intact tympanic membrane, intracranial complications may be the primarily diagnosis, which should be paid much attention by multidisciplinary team. HRCT and audiology were valuable for early diagnosis.</p>

The correlations between varying tinnitus severity and anxiety and depression in non-acute tinnitus patients / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To investigate the correlation betwen varying degrees of non-acute tinnitus and anxiety and depression.@*METHOD@#Seventy-seven outpatients with non-acute tinnitus as their in chief complaint were submitted to Tinnitus Handicap Inventory(THI), Self-Rating Anxiety Scale(SAS), and Self-Rating Depression Scale (SDS).@*RESULT@#THI and its three subscales were found to have significant correlations with SAS and SDS. The group (THI ≥ 38) had more anxiety and depression than the mild (THI < 38). Significant correlations were also observed between THI, SAS and SDS in the group with THI ≥ 38, in contrast with the group of THI < 38.@*CONCLUSION@#Patients with THI ≥ 38 suffered from severe anxiety and depression than the mild. Doctors should pay more attention to these patients, especially their psychological disorders.

OBJECTIVE@#To evaluate the clinical manifestation of Mondini dysplasia with cerebrospinal fluid leakage and investigate the effect of the surgical repair through trans-horizontal semicircular canal and vestibule approach.@*METHOD@#Four cases which were operated by the approach of trans-horizontal semicircular canal and vestibule in our hospital were analyzed retrospectively.@*RESULT@#The leakages were all stopped by the primary surgical closure after six-month follow up.@*CONCLUSION@#Mondini dysplasia should be considered in children or teenagers with recurrent bacterial meningitis whether or not with otorhinorrhea. Pure tone audiometry and a temporal bone CT or MRI will confirm the diagnosis. A trans-horizontal semicircular canal and vestibule approach is an effective and simple way for the treatment.

The configuration of soft palate muscular phenotype in obstructive sleep apnea hypopnea syndrome / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the mRNA expression of muscle phenotype and collagen of soft palate and pathology in obstructive sleep apnea hypopnea syndrome (OSAHS).@*METHOD@#We used the Real-time PCR to test the mRNA expression of soft palate muscle myosin heavy chain (MyHC) phenotype and collagen in 12 OSAHS patients and 8 control patients. We also distinguished the muscle isoforms I , II with ATPase staining, then counted the numbers of isoforms muscle fiber.@*RESULT@#The mRNA expression of OSAHS group was more than control group in II A MyHC phenotype (P<0.01). The number of OSAHS group muscle fibre I isoform was less than control group with pH4. 3 ATPase staining (P<0.05).@*CONCLUSION@#Compare to control group, the enhancement happened in the mRNA expression of II A MyHC phenotype which can increase the velocity and power but de crease the enduring quality of muscle in OSAHS, and the reduce be in the I MyHC isoform of muscle fiber that can cause muscle velocity become slower and persistency become longer in OSAHS patients.

The effect of reversal steps stapedotomy on the treatment of otosclerosis / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To determine the efficacy of reversal steps stapedotomy in the treatment of otosclerosis.@*METHOD@#From January 2006 to December 2009, a total of 70 patients (81 ears) with otosclerosis who underwent stapedotomy were retrospectively evaluated. Among these 81 ears, 41 ears underwent classical stapedotomy and 40 ears underwent reversal steps stapedotomy. We compared the postoperative results of pure tone tes , the intraoperative complications of stapes and incus and the incidence rate of postoperative vertigo after surgery between the two groups.@*RESULT@#The rate of postoperative air bone gap < or = 20 dB was 70.7% in the classical stapedotomy group and was 80.0% in reversal steps stapedotomy group. There were no significant differences between the two groups (P =0.181). The reversal steps stapedotomy group seem to had less complications of stapes and incus. The incidence rate of postoperative vertigo in reversal steps stapedotomy group significantly lower than in classical stapedotomy group (P = 0.037).@*CONCLUSION@#Reversal steps stapedotomy can effectively improve the hearing of patients with otosclerosis and can reduce the complications of stapedotomy.

OBJECTIVE@#To study the management of basic parameters related to individual piston shaping on malleostapedotomy by MDST 3D reconstruction and microanatomy and to assess the accuracy of MDST method.@*METHOD@#Ten Chinese temporal bones without ear diseases were numbered randomly and scanned by GE Light Speed Ultra 64 rows of spiral CT. 3D structure of ossicular chain were reconstructed by MPR and VR methods in AW4. 1 workstation. Then measurements of distances between stapes head to stapes footplate (A line), and manubrium to stapes head (B line), and manubrium to stapes footplate (C line), angle between line A and line B (angle AB) are completed. After that, all samples of temporal bone were undergone canal wall down mastoidectomy under microscope and the relevant measurements were completed.@*RESULT@#The MPR and VR technique of MDCT reconstructed ossicular chain clearly, and revealed the spatial relationship between every structure stereoscopically. Respectively, lengths of A, B, C line by MDST and microanatomy are (3.42 +/- 0.86) mm and (3.60 +/- 0.94) mm, (3.42 +/- 0.80) mm and (2.96 +/- 0.42) mm, (5.86 +/- 0.60) mm and (6.22 +/- 1.10) mm, while angle AB (141.05 +/- 30.07) degrees and (144.57 +/- 41.86) degrees. There are no statistically significant differences between two groups (P>0.05).@*CONCLUSION@#The MPR and VR technique of MDCT can clearly reconstructed the 3D shapes of the temporal bone and finish the exactly managements on A, B, C lines and AB angel which is crucial for shaping a individual piston on malleus-to-oval window surgery.

Malleostapedotomy in stapes surgery for otosclerosis with malleus/incus mobility disorder / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To evaluate the feasibility, safety and effectiveness of malleostapedotomy based on malleus-oval window technique in otosclerosis with malleus/incus mobility disorder.@*METHOD@#Six cases with malleostapedotomy on stapes footplate fixation accompanied by malleus/incus movements disorder from March 2005 to March 2007 were analyzed retrospectively, when totally 78 cases of conventional stapes surgeries were performed on isolated otosclerosis . The surgical procedures, intraoperative findings and postoperative vertigo as well as pure tone gain were discussed.@*RESULT@#All of the 6 cases showed stapes footplate fixation. Both abnormal incudomalleolar joint and incudostapedial joint were found in 2 cases. It was suspected that previous inflammation resulted in yellowish mucosa, ossicular malformation and stiffness. The third one showed local tympanosclerosis in the attic. In another 2 cases, idiopathic malleus head fixation related to the anterior and superior mallear ligament abnormal were presented while a surgical incudomalleolar joint dislocation prior to the observation happened in the last one. Among these 6 cases, there was no 4.0 Hz notch and postoperative vertigo which needs a further care. Postoperative air-bone gap on 0.5 kHz, 1.0 kHz, 2.0 kHz, 4.0 kHz averaged less than 10 dB. All the patients had been followed up for 3 months.@*CONCLUSION@#Malleostapedotomy based on malleus-oval window technique is a safe and effective procedure available for otosclerosis with malleus/incus movement disorder from different origins.
