Maxillary Swing Approach for Removal of Palatal Carcinoma: A Modified Procedure.

Introduction: We report a modification of the maxillary swing approach to remove a palatal tumor while preserving the anterior alveolar area.

Methods: Case report using clinical records.

Results: The patient was a 54-year-old male.

Heterogeneity of odorant identification impairment in patients with Alzheimer's Disease.

Alzheimer's disease (AD) patients exhibit olfactory dysfunction. However, the olfactory declineti precise nature is not fully understood. One hundred patients (60 AD, 28 amnestic mild cognitive impairment (aMCI), 12 Normal) were enrolled.

Contributions of Coding Efficiency of Temporal-Structure and Level Information to Lateralization Performance in Young and Early-Elderly Listeners.

The performance of a lateralization task based on interaural time or level differences (ITDs or ILDs) often varies among listeners. This study examined the extent to which this inter-listener variation could be accounted for by the coding efficiency of the temporal-structure or level information below the stage of interaural interaction. Young listeners (20s to 30s) and early-elderly (60s) listeners with or without mild hearing loss were tested.

Bilateral cervical fistulas from heterotopic salivary gland tissues.

A 24-year-old male was referred to our department with intermittent clear drainage in both sides of the middle neck that did not increase while eating. On physical examination, there were fistulas in both sides of the neck, anterior to the sternocleidomastoid muscles. Fistulography revealed a 9-mm-long sinus from the left fistula, extending in the medial-caudal direction.

Diffuse large B-cell lymphoma in the sphenoid sinus mimicking fibrous dysplasia in CT and MRI.

We present a 70-year-old man with lymphoma who presented with a right eye movement disorder. CT examinations showed 'ground-glass' appearance extending around the right sphenoid sinus which suggested fibrous dysplasia. However, biopsy from the mass histologically proved it to be diffusing large B-cell lymphoma and positron emission tomography examinations revealed increased fluorodeoxyglucose (FDG) uptake around the right sphenoid bone and multiple spinal bones.

Factors that account for inter-individual variability of lateralization performance revealed by correlations of performance among multiple psychoacoustical tasks.

This study explored the source of inter-listener variability in the performance of lateralization tasks based on interaural time or level differences (ITDs or ILDs) by examining correlation of performance between pairs of multiple psychoacoustical tasks. The ITD, ILD, Time, and Level tasks were intended to measure sensitivities to ITD; ILD; temporal fine structure or envelope of the stimulus encoded by the neural phase locking; and stimulus level, respectively. Stimuli in low- and high-frequency regions were tested.

How independent are the pitch and interaural-time-difference mechanisms that rely on temporal fine structure information?

The temporal fine structure (TFS) of acoustical signals, represented as the phase-locking pattern of the auditory nerve, is the major information for listeners performing a variety of auditory tasks, e.g., judging pitch and detecting interaural time differences (ITDs).

Effect of the canalith repositioning procedure on subjective visual horizontal in patients with posterior canal benign paroxysmal positional vertigo.

Conclusion: Substantial numbers of patients with posterior canal benign paroxysmal positional vertigo (p-BPPV) have signs of utricular dysfunction at baseline. This improves after performing the canalith repositioning procedure.

Objective: To evaluate the changes of subjective visual horizontal (SVH) in patients with p-BPPV before and after treatment with the canalith repositioning procedure.
