Journal of Otology 2006年第1期1卷 25-29页

作者： HAN Dongyi, YU Limei, YANG Shiming, YU LimingDepartment of Otolaryngology-Head and Neck Surgery, PLA General Hospital, Beijing 100853 Department of Otolaryngology-Head and Neck Surgery PLA General Hospital Beijing 100853

Objective To report the authors' experiences in hearing preservation during acoustic neuroma (AN) resection procedures. Methods Two cases of AN removal via retrosigmoid approach were reviewed. Hearing preservation was attempted in the aid of endoscopic technique along with continuous monitoring of the compound action potential (CAP) and auditory brainstem response(ABR) during the surgery. Results The tumor in Case 1 was 1.5 cm in diameter. The average pure-tone hearing threshold was 30 dB HL and ABR was normal. Waves I, III and V of ABR were present following tumor removal. At 7th month follow-up, audiometric thresholds and ABR inter-peak intervals had recovered to pre-operative levels, with normal facial nerve function. The patient in Case 2 had bilateral AN. The tumors measured 4.0 cm(left) and 5.0 cm (right) on MRI scans. The AN on the right side was removed first, followed by removal of the left AN four months later. Intraoperative CAP monitoring was employed during removal of the left AN. While efforts to preserve the cochlear nerve were not successful, CAPs were still present after tumor removal. Conclusions Intraoperatively recorded CAPs are not reliable in predicting postoperative hearing outcomes. In contrast, ABRs are an indicator of function of the peripheral auditory pathway. Presence of waves I, III and V following tumor removal may represent preservation of useful hearing.

Intraoperative facial motor evoked potentials monitoring with transcranial electrical stimulation for preservation of facial nerve function in patients with large acoustic neuroma

引用

Chinese Medical Journal 2007年第4期120卷 323-325页

作者： LIU Bai-yun TIAN Yong-ji LIU Wen LIU Shu-ling QIAO Hui ZHANG Jun-ting Jim Gui-jun Department of Neurosurgery Beijing Tiantan Hospital CapitalMedical University Beijing 100050 China Beijing Neurosurgical Institute Beijing 100050 China

Background Although various monitoring techniques have been used routinely in the treatment of the lesions in the skull base, iatrogenic facial paresis or paralysis remains a significant clinical problem. The aim of this study was to investigate the effect of intraoperative facial motor evoked potentials monitoring with transcranial electrical stimulation on preservation of facial nerve function. Method From January to November 2005, 19 patients with large acoustic neuroma were treated using intraoperative facial motor evoked potentials monitoring with transcranial electrical stimulation （TCEMEP） for preservation of facial nerve function. The relationship between the decrease of MEP amplitude after tumor removal and the postoperative function of the facial nerve was analyzed. Results MEP amplitude decreased more than 75% in 11 patients, of which 6 presented significant facial paralysis （H-B grade 3）, and 5 had mild facial paralysis （H-B grade 2）. In the other 8 patients, whose MEP amplitude decreased less than 75%, 1 experienced significant facial paralysis, 5 had mild facial paralysis, and 2 were normal. Conclusions Intraoperative TCEMEP can be used to predict postoperative function of the facial nerve. The decreased MEP amplitude above 75 % is an alarm point for possible severe facial paralysis.

Background Small acoustic neuromas seldom result in typical vestibular symptoms, despite the tumor arising from the vestibular nerve. In this study, we have shown that abnormal gait in eleven patients with small acoustic neuroma could be detected in gait analysis by the use of tactile sensor. Patients displayed no oculomotor abnormality and had tumors less than 10 mm from the porus acoustics. Methods Gait related parameters including the coefficients of variations （CV） of stance, swing, double support, area ratio of trajectories of center of force （TCOF）, in addition to the foot pressure difference between both feet, were used for assessment of gait.

Objective: To determine the best follow-up period with regard to curative effect for acoustic neuroma treated with a gamma knife. Methods: Sixty cases of acoustic neuroma were treated with a gamma knife. The follow-up period was from 3 to 102 months. Changes in the lesions and peripheral tissues and clinical symptoms were compared and the curative effectiveness of gamma knife treatment was evaluated. Results: The highest total effective rate (92.3%) was in the third period. There was a significant difference in the tumor size postoperatively. There was no edema in the peripheral tissues surrounding the tumor. It was not obvious that clinical symptoms changed. Conclusion: In this report, the best follow-up period was 24-36 months. Gamma knife treatment was still effective after 60 months post-operation.

Background Tinnitus is very common in patients with vestibular schwannoma (VS). We analyzed the related factors of tinnitus after *** One hundred seventy-three patients diagnosed with unilateral VS operated via the retrosigmoid approach were included in the study. All patients underwent relevant examinations and completed the THI scale before surgery and 6 months after surgery. The prognosis of tinnitus was evaluated according to the changes in *** Of the 129 preoperative tinnitus patients, postoperative tinnitus resolved in 12.4%, improved in 29.5%, remained unchanged in 28.6%, and worsened in 29.5%. 18.2% of 44 patients without preoperative tinnitus appeared new-onset tinnitus postoperatively. Thirty-six patients never had tinnitus. Patients with smaller tumor sizes (≤ 3 cm) were more likely to experience preoperative tinnitus. Younger patients and those with serviceable hearing preoperatively were more likely to report their tinnitus unchanged or worsened. A new onset of postoperative tinnitus in the preoperative non-tinnitus group was found in better preoperative hearing *** In this study, 70% of patients had persistent tinnitus after vestibular schwannoma resection. The prognosis of tinnitus was influenced by age and preoperative hearing function. Tinnitus is a bothersome symptom and is often underestimated by doctors. Assessment of tinnitus is mandatory during the management of vestibular schwannoma.

Neuropathic pain is chronic pain generated by disorders of the peripheral and central nervous system, including skull base tumours. A skull base tumour can be any type of tumour that forms in the skull base, and this includes vestibular schwannomas which arise from the sheath of the inner ear vestibulocochlear nerve(eighth cranial nerve). Growth of the tumour, surgical resection, and/or stereotactic radiotherapy may result incompression and/or irritation of the fifth cranial nerve(trigeminal nerve) resulting in facial pain and/or numbness. Non-trigeminal afferent input may contribute to the wide constellation of symptoms seen in orofacial pain patients. The purpose of this report was to develop a decision tool to guide the recognition and treatment of neuropathic pain in this specialized population. Recommendations for treatment are based on evidence presented in Canadian and international neuropathic treatment guidelines. Algorithms are included for assessment and treatment of adult patients with agents that are recognized to have analgesic efficacy within the broad context of neuropathic pain.

Isolated cochlear neuritis from varicella reactivation mimicking a vestibular schwannoma

引用

World Journal of Otorhinolaryngology-Head and Neck Surgery 2016年第3期2卷 -页

作者： Adam D. Goodale Justin S. Golub Rebecca S. Cornelius Ravi N. Samy Department of 0tolaryngologyeHead and Neck Surgery University of Cincinnati Medical Center Cincinnati 0H 45267 USA Department of 0tolaryngologyeHead and Neck Surgery Columbia University Irving Medical Center New York NY USA Department of Radiology Section of Neuroradiology University of Cincinnati Medical Center Cincinnati 0H 45267 USA

We present a case of a patient with progressive unilateral sensorineural hearing loss and tinnitus with internal auditory canal enhancement on magnetic resonance imaging (MRI) secondary to isolated cochlear neuritis from varicella reactivation. MRI following antiviral treat-ment showed resolution of enhancement. Varicella reactivation is commonly seen in the form of Ramsay Hunt syndrome, which is known to produce abnormal MRI enhancement from facial and vestibulocochlear neuritis;however, its characteristic clinical signs aid the diagnosis. This case is unique in that the only manifestation of varicella infection was unilateral hearing loss. This case outlines the importance of maintaining a broad differential diagnosis in the evaluation of unilateral hearing loss as well as recognizing the limited specificity of MRI.
