BACKGROUND Sinonasal inverted papilloma (IP) is an uncommon nasal tumor. It is known for being locally invasive and recurrent, with a high probability of malignant transformation. Accurate initial staging and close surveillance are critical in the management of the disease. METHODS AND RESULTS Fluorine-18 fluorodeoxyglucose positron emission tomography(More)
CONCLUSION We conclude that not all low-tone sudden deafness (SD) patients suffered from endolymphatic hydrops even if they had vertigo attack at the onset and that electrocochleography (ECochG) was a useful prognostic tool. OBJECTIVES To investigate whether low-tone SD was a precursor of Meniere's disease and whether patients with low-tone SD suffered(More)
CONCLUSION Middle ear pressure treatment by the tympanic membrane massage (TMM) device as well as the Meniett device is effective and provides minimally invasive options for intractable vertigo in patients with Meniere's disease (MD) and delayed endolymphatic hydrops (DEH). OBJECTIVE The effects of the TMM device were evaluated according to the criteria(More)
To identify epidemiologic characteristics of definite cases of Ménière's disease (DMD), we conducted retrospective surveys of the period 1990-2004 of the Nishikubiki district and of the period 1980-2004 of Toyama Medical and Pharmaceutical University. Three hundred and seventy-five patients (50 from Nishikubiki, 325 from Toyama) were diagnosed with DMD(More)
We report a case of mumps deafness with acute vestibular symptoms secondary to both retrolabyrinthine and inner ear dysfunction. To our knowledge, no such case has been reported elsewhere. The patient was a 6-year-old girl in whom mumps deafness was initially diagnosed. Two days after onset of the hearing impairment, severe vertigo developed. Neurotologic(More)
OBJECTIVES To overcome the lack of the autografts in revision ear surgery, the usefulness of human amniotic membrane (AM) patches as a dressing substitute for fascia grafts of the temporal muscle (temporalis fascia graft) was investigated in canal wall down tympanoplasty. STUDY DESIGN Retrospective chart review. METHODS In 11 ears of 11 patients, the AM(More)
CONCLUSION The findings suggest that sound-evoked myogenic potentials on the guinea pig sternocleidomastoid muscle (SM) originate from the vestibular end organ and not from the cochlea of the inner ear. OBJECTIVE Studies in animals of the sound evoked vestibular myogenic potentials on the SM should aid in elucidating the pathway of the vestibular-evoked(More)
OBJECTIVE The aim of this study was to elucidate the neural pathway for sound-evoked myogenic potentials (SEMPs) in monkeys with characteristics similar to those of vestibular evoked myogenic potentials in humans. METHODS Six macaque monkeys were examined. The effects of total and selective vestibular nerve section on the SEMPs were evaluated in three(More)
OBJECTIVE The aim of this study was to investigate the usefulness of a Nucleus C124M cochlear implant in a patient with mitochondrial encephalopathy, lactic acidosis and stroke-like episodes (MELAS) syndrome. MATERIAL AND METHODS A 29-year-old woman with MELAS syndrome presented with sensorineural hearing loss and diabetes mellitus and underwent(More)
CONCLUSIONS It was shown that practicing with a tangible head model with semicircular canals is a useful educational tool for learning the physical treatment for BPPV. OBJECTIVES To assess the efficacy of using a tangible head model with semicircular canals to teach the physical treatment for BPPV. METHODS This study compared the number of canalith(More)
