Relationship between Work Ⅱ type of congenital first branchial cleft anomaly and facial nerve and surgical strategies / 中华耳鼻咽喉头颈外科杂志

Objective@#To investigate the relationship between Work Ⅱ type of congenital first branchial cleft anomaly (CFBCA) and facial nerve and discuss surgical strategies.@*Methods@#Retrospective analysis of 37 patients with CFBCA who were treated from May 2005 to September 2016. Among 37 cases with CFBCA, 12 males and 25 females; 24 in the left and 13 in the right; the age at diagnosis was from 1 to 76 ( years, with a median age of 20, 24 cases with age of 18 years or less and 13 with age more than 18 years; duration of disease ranged from 1 to 10 years (median of 6 years); 4 cases were recurren after fistula resection. According to the classification of Olsen, all 37 cases were non-cyst (sinus or fistula). External fistula located over the mandibular angle in 28 (75.7%) cases and below the angle in 9 (24.3%) cases.@*Results@#Surgeries were performed successfully in all the 37 cases. It was found that lesions located at anterior of the facial nerve in 13 (35.1%) cases, coursed between the branches in 3 cases (8.1%), and lied in the deep of the facial nerve in 21 (56.8%) cases. CFBCA in female with external fistula below mandibular angle and membranous band was more likely to lie deep of the facial nerve than in male with external fistula over the mandibular angle but without myringeal web.@*Conclusions@#CFBCA in female patients with a external fistula located below the mandibular angle, non-cyst of Olsen or a myringeal web is more likely to lie deep of the facial nerve. Surgeons should particularly take care of the protection of facial nerve in these patients, if necessary, facial nerve monitoring technology can be used during surgery to complete resection of lesions.

The effect of binaural bi-modal fitting on speech recognition of cochlear implant recipients with low frequency electrodes incompletely implanted / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To study the effect of binaural bi-modal fitting (one cochlear implant and a contralateral hearing aid) on speech recognition of cochlear implant recipients with low frequency electrodes incompletely implanted.@*METHOD@#A total of 15 cochlear implant(CI) users who have low residual hearing (250 Hz 45-90 dBHL, 500 Hz 75 - 100 dBHL) of their non surgery ears. We closed the top three electrodes to simulate the state of low-frequency electrodes incompletely implanted by fitting software. (1) The same tester received twice speech recognition tests in incompletely implanted state, one test used single CI model and the other used binaural bi-modal fitting model. (2)The same tester received above twice speech recognition tests again, but in completely implanted state. Then we compared the results of tests.@*RESULT@#The CI users used binaural bi-modal fitting have higher speech recognition score than the same users used unilateral cochlear implant model in low-frequency electrodes incompletely implanted state(P<0. 05). The gap between the scores of the tests by using two usage patterns in low frequency electrodes incompletely implanted state was more than that in completely implanted state (P<0. 05).@*CONCLUSION@#Binaural bi-modal fitting can help CI users to improve their speech recognition ability in low-frequency electrodes incompletely implanted state.

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.

Application of HRCT multi-planar reconstruction for measuring cochlear morphology in cochlear implantation / 临床耳鼻咽喉头颈外科杂志

OBJECTIVE@#To explore the value of high-resolution temporal bone CT (HRCT) multi-planar reconstruction (MPR) technique for measuring cochlear morpholog in the preoperative evaluation of cochlear implant.@*METHOD@#We retrospectively analyzed the clinical data of 80 cochlear implant recipients. The groups were investigated in our research according to the patient's sex, age and whether the inner ear is malformed or not. Temporal bone HRCT MPR was applied to analyze the measurement parameter in the standard orientation of the cochlea image: the largest distance from the round window to the lateral wall (distance A), the perpendicular distance (B) and angle of the basal turn of the cochlea relative to the midsagittal plane (γ). Reproducibility of the measured data was evaluated and the results between the different groups were compared.@*RESULT@#Measurement of parameter values between the intraobserver and interobserver showed good reproducibility. In normal group, distance A [(8.79±0.34) mm] and perpendicular distance B [(6.58±0.28) mm] of males' cochleae were significantly larger than A [(8.53±0.47) mm] and B [(6.22±0.43) mm] of females' (P0.05). The A and B values didn't change with age (P>0.05), but the angle γ tended to decrease with increasing age (r=-0.25, P0.05).@*CONCLUSION@#HRCT MPR technique is simple and reliable in measurement of cochlear morphology. It can be used to guide the surgery and provide an objective basis for designing the personalized electrode. More clinical application of this technology is recommended.

Narrow-band level set and visualization technology for cochlea segmentation / 生物医学工程学杂志

Segmentation is a precondition step for modeling and analysis of the cochlea. In this paper, an interactive segmentation approach with a combination of 3D (three-dimensional) narrow-band level set algorithm and visualization technology was adopted to separate the cochlea. The 3D narrow-band level set algorithm was used to separate the objective of interest from volume data, and the visualization technology was used to display the segmented result. Users could modify intermediate parameters based on the direct 3D visual feedback until getting satisfying result. The basic principle and characteristics of level set and narrow-band level set algorithms were described in detail. The 3D narrow-band level set algorithm was successfully used to separate the cochlea from spiral CT images of the temporal bone. The experimental results show that the interactive method combining the narrow-band level set algorithm with visualization technique is capable of segmenting the cochlea from the medical volume data. Compared with the method of segmenting object from image volume slice by slice, our method can save much time.
