To prove the hypothesis that speech after glossectomy would be improved more by increasing the mobility of the remaining tongue rather than by increasing its volume, the speech intelligibility of 4 glossectomy patients was investigated before and after a secondary operation in which a split skin graft was used to mobilize the residual tongue. In each case,(More)
Linguapalatal contact patterns and the time course of changes in contacts during utterances of/asa, ata, a sa, aca/ were measured using electropalatography (EPG). The relations between these data and perceptual scores in 17 glossectomized patients after various surgical methods were examined. The linguapalatal contact patterns produced during perceptually(More)
The role of visual feedback in the treatment of defective /s/ sounds in patients with cleft palate is described. Six patients with cleft palate who were similar in age, velopharyngeal function, and type of misarticulation were selected for this study. Treatment was provided using either visual feedback or no visual feedback. Visual feedback for tongue(More)
The dynamic palatograph is an electrical apparatus that generates a visual display of constantly changing palatolingual contact as a function of time, using an artificial palatal plate with affixed electrodes. This paper describes a technique of speech therapy incorporating dynamic palatography for a cleft palate patient. The patient, a 6-year-old Japanese(More)
Lingual-palatal contact patterns and auditorily judged misarticulations, classed as palatalized misarticulation (PM), lateral misarticulation (LM), nasopharyngeal misarticulation (NM), and other distortions were compared in 53 Japanese cleft palate patients. Velopharyngeal function of these patients was considered within normal limits. Contact patterns were(More)
Rehabilitation of the oral cancer patient should aim to achieve not only morphological restoration but also post-operative functions. However, there are few reports describing quantitative evaluation of the latter. The authors have attempted quantitative evaluation of post-operative articulatory function after glossectomy, and report the evaluation of it by(More)
Post-surgical maxillary defects have recently been reconstructed by microvascularized free flaps. However, few reports have evaluated the resulting speech function. This study compared the speech intelligibility of four maxillectomy patients who underwent reconstruction by rectus abdominis myocutaneous flaps (RAMCF) with that of four non-reconstructed(More)
We investigated factors affecting the timing of signal detection by comparing variations in reporting time of known and unknown ADRs after initial drug release in the USA. Data on adverse event reactions (AERs) submitted to U.S. FDA was used. Six ADRs associated with 6 drugs (rosuvastatin, aripiprazole, teriparatide, telithromycin, exenatide, varenicline)(More)
