OBJECTIVE: To compare the vertigo controlling situation between the endolymphatic sac decompression(ELSD) and semicircular canal occlusion (SCO) in stage 4 Ménière disease. METHOD: Fourteen patients who underwent endolymphatic sac decompression and 9 patients who underwent semicircular canal occlusion from 2009 to 2013 were followed. All patients has complete preoperative examination and postoperative follow-up. RESULT: The vetigo control of the patients underwent endolymphatic sac decompression: completely control 35.7%; basic control 28.6%; partly control 14.3%; the vetigo control of the patients underwent semicircular canal occlusion: completely control 88.9%; basic control 11.1%. CONCLUSION ELSD and SCO are alternative methods for the patients of stage 4. SCO has a much highter complete vertigo control rate. For the patients without practical listening, SCO is a better choice.

OBJECTIVE: To investigate the new method of modified skin flap of external canal in auditory canal shaping to enlarge at radical mastoidectomy in endaural incision. METHOD: From 1999 to 2009, 412 patients with 428 ears in operation were randomly divided into two groups. Patients underwent open mastoidectomy and some patients were performed concurrent tympanoplasty. A group (control group)were operated in traditional skin flap of external canal, B group is modified group. Bleed and effusion from the wound surface, the time of dry ear and the change of diameter of extermal acoustic meatus after one year were observed after the surgeries and deal the results with SPSS. RESULT: The difference had statistical significance in bleed and effusion from the wound surface, the time of dry ear and the shrink of external acoustic meatus in 12 months among two groups. CONCLUSION Modified skin flap of external canal in auditory canal shaping to enlarge can help to make a no-wound dehiscence by wiping out the raw surface of external acoustic meatus. It is better than traditional skin flap of external canal.

BACKGROUNDSuperior semicircular canal dehiscence (SSCD) is gradually recognized by otologists in recent years. The patients with SSCD have a syndrome comprising a series of vestibular symptoms and hearing function disorders which can be cured by the operation. In this study, we evaluated the characteristics of patients with SSCD and determined the effectiveness of treating this syndrome by resurfacing the canal via the transmastoid approach using a dumpling structure.

METHODSPatients with SSCD, confirmed by high-resolution computed tomography and hospitalized at Beijing Tongren Hospital between November 2009 and October 2012, were included in the study. All of the patients underwent the unilateral transmastoid approach for resurfacing the canal, and received regular follow-up after surgery. Data from preoperative medical records and postoperative follow-up were comparatively analyzed to evaluate the effect of surgery.

RESULTSIn total, 10 patients and 13 ears (three left ears, four right ears, three bilateral ears) were evaluated in the study, which included 7 men and 3 women. Different symptoms and distinctive manifestations of vestibular evoked myogenic potential were found in these patients. After surgery, 4 patients had complete resolution, 5 had partial resolution, and 1 patient, with bilateral SSCD, had aggravation. None of the patients suffered from serious complications such as sensorineural hearing loss, facial paralysis, cerebrospinal fluid leakage, or intracranial hypertension.

CONCLUSIONSIn patients with unilateral SSCD, resurfacing the canal via the transmastoid approach using a dumpling structure is an effective and safe technique. However, more consideration is needed for patients with bilateral SSCD.

Evaluation of postoperative hearing acuity and equilibrium was performed in four patients with labyrinthine fistula caused by iatrogenic procedure. Surgical trauma inflicted upon the membranous labyrinth is an uncommon, but often catastrophic, complication of chronic ear surgery. The most vulnerable areas are the oval window and the lateral semicircular canal. Methods of injury include subluxation of the foot plate, fracture of the lateral canal by drill or chisel, and accidental opening of the labyrinth. Three cases of fistula of the lateral and posterior canal during ear surgery are presented. All of three occured while drilling. The other one occured due to iatrogenic stapedectomy. The interrupted semicircular canals were obliterated firmly with autologous materials such as fascia, perichondrium, bone chips, and cartilage. These cases were documented by pre and post operative audiograms, vestibular function tests. One interesting finding was that none of these cases were compromised cochlear function. The dictum that an accidentally opened labyrinth will automatically result in a dead ear is shown to be not necessarily true. These cases indicates that manipulation of the semicircular canal with awareness can be conducted without damaging the cochlear function, and that the treatment of labyrinthine fistulas shoud be performed very carefully but not so conservatively as to lead to future problems.

Postoperative vertigo can occur after stapes surgery in approximately 5% of the patients, which more commonly presents immediately after surgery rather than in the delayed period. Isolated delayed vertigo after stapes surgery is commonly related to perilymphatic fistula. Herein we report a 36-year-old female patient who developed positional vertigo 18 days after stapes surgery demonstrating severe geotropic horizontal positional nystagmus on both sides during supine roll test. This patient was eventually diagnosed as the horizontal semicircular canal benign paroxysmal positional vertigo (BPPV) on the left side. This is a rare case of delayed vertigo following stapes surgery caused by BPPV rather than perilymphatic fistula.

Electrode array misplacement is a rare complication of cochlear implant. This article reports an 11-year-old boy who was mistakenly implanted the cochlear electrode array into the superior semicircular canal during the initial cochlear implant. After the diagnosis was confirmed, he underwent a second cochlear implant and the electrode array were successfully implanted into the cochlea. This article conducted a systematic review of the literature on electrode array misplacement, and the causes of electrode array misplacement were analyzed from different implantation position.

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.
