[Clinical analysis of bilateral same-day myringoplasty for 22 cases with bilateral tympanic membrane perforation].

April 2013
Article Synopsis
- The study assessed the safety and effectiveness of performing bilateral same-day myringoplasty on patients with bilateral tympanic membrane perforations, involving 22 patients who underwent the procedure.
- Patients' hearing improved by an average of 18 dB post-operation, with a high success rate of tympanic membrane closure at 93.2%.
- While the bilateral group experienced some temporary ear fullness as a postoperative complication, overall results indicate that this method is feasible and safe, distinguishing it from the results of a control group who had monaural (single ear) surgery.
[Functional analysis of the vertical semicircular canal using vertical plane swing test and study of its normal values].

January 2012
Objective: The purpose of this study was to set up a method to analyze the vertical semicircular canal function and study the normal values of the vertical semicircular canal function using the vertical plane swing test.
Methods: A prospective analysis of 100 normal persons (aged from 18 to 59 years), who were treated by using the vertical plane swing test with the newly developed automatic vestibular function diagnosis and therapy system (SRM-IV). These persons were rotated 180° at a sinusoidal speed (acceleration 45°/s, maximum speed 90°/s) in the vertical semicircular canal plane.

[Operation of hypopharyngeal carcinoma with restrained vocal cord motility].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
March 2011
Objective: To explore the feasibility of laryngeal function preservation in surgical treatment of hypopharyngeal carcinoma with restrained vocal cord motility.
Methods: Twenty-six cases of hypopharyngeal carcinoma treated with conservative hypopharyngectomy were retrospectively analyzed. Partial resection of pyriform sinus and partial laryngectomy were performed.

[Study of the key points and safety measures during perioperative period in patients with obstructive sleep apnea hypopnea syndrome].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
May 2010
Article Synopsis
- The study aimed to evaluate safety measures in patients with obstructive sleep apnea undergoing uvulopalatopharyngoplasty (UPPP) to reduce major complications.
- It analyzed data from 1446 OSAHS patients, comparing outcomes before and after the implementation of standardized management measures in 2004, revealing a significant reduction in complications.
- Five critical perioperative phases were identified: preoperative exams, intubation, surgery, postoperative extubation, and care, highlighting their importance in preventing risks and complications.
[Molecular etiology of non-syndromic hearing impairment in a Chinese family].
Zhonghua Yi Xue Za Zhi
September 2009
Article Synopsis
- The study aimed to explore the genetic causes of non-syndromic hearing loss in a Chinese family with a maternal history of deafness.
- The researchers sequenced mitochondrial DNA and the GJB2 gene from blood samples of two affected sisters, finding a mutation in the mitochondrial gene but no issues with GJB2.
- The results indicated that individual genetic backgrounds can influence the severity and characteristics of hearing impairment within the same family.
[Applied study of voice function rehabilitation by mucosa tube performed in operation of late laryngocarcinoma.].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
November 2009
Objective: To study the voice function rehabilitation by mucosa tube performed in operation of late laryngocarcinoma and to improve the survival quality of patients with late laryngocarcinoma.
Methods: Forty-six patients were treated between Oct. 1991 and May 2006, including 41 males and 5 females.
[Analysis and application of the images from the segmenting CT in the space of nasal endoscope].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
October 2009
Objective: To analyze the images from the segmenting CT in the space of nasal endoscope and to observe the benefits in applying the method in endoscopic sinus surgery.
Methods: Five patients with inverted papilloma and ten patients with chronic rhinosinusitis were enrolled. The images from the coronal CT were put in the ideal model of the nasal cavity, which had been designed by SketchUp software package, and the space of the model in the 0 degree rod-lens telescope was simulated and observed according to definite elevation angle between the endoscope and bottom of nasal cavity and the distance of the endoscope entering the nasal cavity.
[Three-axis otoconia maneuver treatment in benign paroxysmal positional vertigo].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
October 2008
Objective: To evaluate three-axis otoconia maneuver (TOM) for benign paroxysmal positional vertigo (BPPV).
Methods: The data from twenty BPPV patients who received three-axis otoconia maneuver treatment and 20 BPPV patients who received canalith repositioning (CRP) maneuver treatment were analyzed retrospectively.
Results: There were 17 patients received 1 TOM session and 3 patients received 2 TOM sessions while 16 patients received 1 CRP session and 4 patients received 2 CRP sessions.
[Effect of glutamate on distortion product otoacoustic emission and auditory brainstem response in guinea pigs].
Zhonghua Er Bi Yan Hou Tou Jing Wai Ke Za Zhi
June 2005
Objective: To investigate the changes of the potentials and structure of the guinea pig cochlear during whole cochlear perfusion with glutamate.
Methods: Cochlear microphonics (CM), compound action potential (CAP), distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) were measured to indicate the cochlear functional properties during whole cochlear perfusion. The morphology of the cochlear was monitored by transmission electron microscopy.
