　概要を見る

<p>We reported a 68-year-old female with Creutzfelt-Jakob disease (CJD) presenting hyperparathyroidism. She was suspected as Creutzfelt-Jakob like syndrome at her initial visit to our hospital because of progressive dementia and high level of serum calcium. Finally she was diagnosed as having CJD by the clinical symptoms including progressive dementia and myoclonus and the characteristic patterns of brain CT and electroencephalogram (EEG). CJD presents a variety of symptoms including progressive dementia, apathy and myoclonus. Hyperparathyroidism and toxicity of lithium, delirium and bismuth have been reported to induce similar symptoms of CJD, which are called Creutzfelt-Jakob like syndrome. Therefore, the diagnosis of CJD would be difficult in cases with CJD accompanied with Creutzfelt-Jakob like syndrome. It is rare for otolaryngologists to examine patients with dementia like CJD. However, we have to keep CJD in mind in the diagnosis of hyperparathyroidism. Copyright (C) 2000 Elsevier Science Ireland Ltd.</p>

Vestibular schwannoma presenting as sudden deafness

　概要を見る

<p>In this study, we analysed the clinical and audiological features of 24 vestibular schwannoma patients presenting with sudden deafness who visited our hospital within 10 days after its onset. The relationships between the prognosis of hearing loss and the clinical and audiological features including the pure-tone average (PTA), the presence of dizziness and/or vertigo, the tumour size and the auditory brain stem response (ABR) findings were evaluated. Hearing recovery depended on the PTA and tumour size, but even a small tumour induced sudden deafness. Impaired hearing completely recovered in five our of 24 patients. ABR findings indicated that the aetiology of sudden deafness in the vestibular schwannowa patients might vary in each patient.</p>

<p>Objective: The aim of this study is to describe the long-term outcome of preserved hearing after vestibular schwannoma surgery.Methods: Subjects are 20 unilateral vestibular schwannoma patients whose class A hearing of the AAO-HNS classification was preserved successfully after tumor removal. Hearing preservation surgery was attempted via the middle cranial fossa (MCF) or the extended MCF approach. The follow-up periods ranged from 2 to 16 years. The outcome measures included the pure tone average (PTA) and speech discrimination score (SDS).Results: PTA was maintained in less than 30 dB in 11 out of 20 patients within 2 years follow-up, six out of 13 patients within 4 years follow-up, and two out of five patients within 6 years follow-up, respectively. SDS was maintained in more than 70% in 17 out of 20 patients within 2 years follow-up, ten out of 13 patients within 4 years follow-up, and three out of five patients within 6 years follow-up, respectively.Conclusions: The preserved hearing maintained about more than 40% of the patients with the class A hearing in every 2 years follow-up. From this result, we can conclude that the hearing preservation surgery could be one of the best treatments for vestibular schwannoma patients with class A hearing. However, further study will be needed to clarify the mechanism of the deterioration in hearing after hearing preservation surgery. Copyright (C) 2000 Elsevier Science Ireland Ltd.</p>

Hypoglossal neurinoma

　概要を見る

<p>Two patients presented with hypoglossal neurinoma extending both intra- and extracranially. A 63-year-old male presented with right trigeminal neuralgia and hypoglossal nerve paresis. The intracranial part of the tumor was removed totally via a suboccipital craniectomy. Over-coagulation of the venous collaterals, particularly the emissary veins, resulted in dural venous sinus thrombosis and cerebellar infarction. Unfortunately this patient died. A 48-year-old male presented with pareses of the VII, IX, X, XI, and XII cranial nerves and cerebellar sign. The tumor extended both extra- and intracranially, and was completely removed by opening the hypoglossal canal and the jugular foramen without over-coagulation of the venous collaterals. Preservation of the venous collaterals is very important for the prevention of postoperative venous complications.</p>

　概要を見る

<p>Nodular fasciitis has been generally considered as a benign and probably reactive fibroblastic growth originating from the subcutaneous fascia. In the present paper, we report a case with nodular fasciitis arising in the retroauricular region. The patient was a 23-year-old woman who had noticed a mass about 5 mm in diameter in the left retroauricular region. She was referred to our hospital because the mass was gradually growing and was tender to touch. At the initial examination, a pigmented mass about 1 cm in size was found in the left retroauricular region. The surface was smooth and the mass was freely mobile. Computed tomography (CT) revealed a mass-like tension which showed the same enhancement as a venous intensity. At operation, we found a white solid mass which had no capsule. The mass was easily removed, because it was not adherent to the surrounding tissues. The pathological diagnosis was nodular fasciitis which showed positive immunostaining for vimentin, HHF 35 (muscle actin), type III collagen and lysozyme, but negative immunostaining for desmin, S-100 protein and CD 34. This rare condition can be diagnosed only by pathological examination, however, it must be kept in mind in the differential diagnosis of retroauricular mass lesions.</p>

<p>Salivary gland choristoma (ectopic or heterotopic salivary gland tissue) is a rare condition that occurs in various locations within the head and neck regions. We present a 13-year-old boy with a salivary gland choristoma in the middle ear associated with congenital alopecia around the auricle in addition to facial nerve and ossicular chain abnormalities. Because the lesions commonly involve the facial nerve, intraoperative facial nerve monitoring is helpful in allowing safe biopsy without facial nerve damage.</p>
