JOURNAL FREE ACCESSThis study was designed to show MRI findings of postoperative middle ear pathologies and to discuss the usefulness of Gadolinium-enhanced MRI in evaluating the postoperative state of cholesteatoma.
Thirty-eight ears which underwent intact canal wall tympanoplasty for cholesteatoma were examined. Recurrent cholesteatoma was detected as an iso-intensity area on T1-weighted images with negative enhancement. Notably, residual cholesteatoma were generally depicted as a round iso-intensity area with negative enhancement. Residual cholesteatoma less than 5mm in diameter were, however, not generally detectable with our MRI scanner.
Granulation tissue can be separated from cholesteatoma as an area with positive enhancement. Cholesterol granuloma shows a characteristic high signal pattern on both T1 and T2-weighted images. Hypovascular fibrous tissue and fluid collection may be depicted as a pattern similar to that of cholesteatoma. However, the signal is usually more homogeneous than that of cholesteatoma.
We conclude that Gadolinium-enhanced MRI is useful for detecting postoperative cholesteatoma and avoiding unnecessary second-look operations after cholesteatoma surgery, by the canal-up procedure.View full abstractDownload PDF (4223K) -

JOURNAL FREE ACCESSWe evaluated the relationship between birch pollen allergy and oral and pharyngeal hypersensitivities to certain fruits.
1. Of 171 birch pollen CAP positive (score≥2) patients, twenty two (13%) were revealed to be hypersensitive to apples, eleven (6%) to be hypersensitive to peaches, both rates being higher than those found in patients with other CAP positive reactions (orchard grass pollen CAP, mugwort pollen CAP or Dermatophagoides pteronyssius CAP positive).
2. Among the birch pollen CAP positive patients, the higher the CAP score for birch pollen, the higher the prevalences of hypersensitivity to apples and peaches were found to be.
3. Of 171 birch pollen CAP positive patients, six (3.5%) were revealed to be hypersensitive to kiwi fruit.
Of 253 patients with other CAP positive reactions, three (1%) were revealed to be hypersensitive to kiwi fruit.View full abstractDownload PDF (636K) -

JOURNAL FREE ACCESSWe present a 58-year-old male patient with bilateral cheek swelling and an extraorally protruding tumor who has had deaf mutism since birth. He underwent surgery of the right hard palate 11 years ago. Five years later biopsy was performed for a recurrent lesion diagnosed as pleomorphic adenoma. He refused additional treatment and the size of the tumor subsequently increased slowly. As rapid tumor-growth had been observed since autumn of 1992, he was referred to Tokyo University Hospital.
We took meticulous care of this deaf mute patient, especially from the psychological aspect, which caused him to place great reliance upon us. We perfomed bilateral maxillectomy with partial resection of the right cheek skin and reconstructed his face and palate successfully using both latissmus dorsi and serratus anterior musculocutaneous free flaps with a rib.
Histopathological diagnosis of the tumor was polymorphous low grade adenocarcinoma, which was registered as a definite entity in the WHO Classification in 1991. There was no evidence of local recurrence or metastasis one year postoperatively.View full abstractDownload PDF (3393K) -

JOURNAL FREE ACCESSMany patients with head and neck cancer have a smoking history, and pulmonary complications frequently lead to post-operative death. Due to technical problems, spirometric pulmonary function tests are rarely performed in patients with laryngectomy. The purpose of this study is to evaluate respiratory function in patients with laryngectomy.
We made a tracheal mask with a heat and moisture exchanging baseholder, and used it for spirometry. Eight patients with laryngectomy, including 5 with laryngeal cancer and 3 with hypopharyngeal cancer, were studied. Arterial blood gas analysis and pulmonary function measurements, such as VC, % VC, FEV1.0% and V25/height (V25/HT), were evaluated before and after laryngectomy. Statistical analysis of the data was performed with the Wilcoxon rank-sum test.
The following results were obtained:
1) No statistically significant changes in arterial blood gases and FEV1.0% were found.
2) A statistically significant decrease in VC was found after total laryngectomy (p<0.05).
3) A statistically significant decreas in V25/HT, which reflects small air way closure of the lung, was observed after total laryngectomy (p<0.05). In all cases, the V25/HT value was below normal limits.
We concluded that the decrease in VC was caused by a decrease in dead space in the upper airway, and that V25/HT may be a good parameter for evaluation of pulmonary function after laryngectomy.View full abstractDownload PDF (1695K) -

JOURNAL FREE ACCESSAn A to G transition at nucleotide 3, 243 in the tRNAleu(UUR) gene of mitochondrial DNA (mtDNA) has been suggested to be the disease-related mutation for MELAS (mitochondrial myopathy, encephalopathy. lactic acidosis and stroke-like episodes). Recently, the same mutation has also been found in several pedigrees with maternally inherited diabetes mellitus and sensorineural deafness. We report here a family showing the association of deafness and diabetes mellitus, as the predominant clinical features, with this mutation. The mutation was detected by restriction enzyme analysis of the relevant PCR amplified segment of the mtDNA, in two generations. In this family, it is noteworthy that two members with the mutation had some symptoms of MELAS such as short stature, seizures and mental retardation and that one had no clinical symptoms though the mtDNA mutation was identified in his blood. The findings in this family demonstrate the diversity of clinical expression of the mtDNA mutation and suggest that a combination of sensorineural deafness and diabetes mellitus is only one typical presentation of the various phenotypic features caused by the 3, 243 mutation.View full abstractDownload PDF (832K) -

JOURNAL FREE ACCESSEighteen patients with a 22 channel cochlear implant were evaluated both pre and postoperatively with vestibular function tests; caloric test and body balance test using stabilometry. Preoperative promontory stimulation results and postoperative psychophysical factors of the cochlear implant showed no correlation with the preoperative vestibular function test results. The results of speech perception tests were not affected by the degree of residual vestibular function in any of the patients. However, for patients with deafness for a period of 10 to 20 years, the degree of the residual vestibular function estimated by the caloric test showed a correlation with the results of speech perception tests, significantly in the consonant recognition score. The results, not of length or the Rombberg ratio, but rather of the area of body sway, showed a correlation with the results of speech perception tests; consonant recognition, in patients with a short duration of deafness. Therefore preoperative vestibular function results may be useful as a predictive factor in postoperative speech perception; consonant recognition, for patients with a short duration of deafness. Reduced results of caloric testing after surgery were found in one of 11 patients (9%) with residual vestibular function. The occurrence of vertigo immediately after surgery was observed in 5 of 1 patients (28%), but this symptom was trasient. No change in stabilometry results. pre-versus post-operatively. was observed. Thus, vestibular damage after surgery was considered to be minimal.View full abstractDownload PDF (980K) -

JOURNAL FREE ACCESSWe report a recently encountered case of vascular leiomyoma in the larynx. The patient was a 76-year-old man with a chief complaint of hoarseness. Laryngoscopy revealed a bean-sized, reddish tumor with a smooth surface, suspended from the right vocal cord toward the subglottis. Its border was clear on MR imaging. Tracheotomy was performed under local anesthesia, and laryngomicrosurgery was then carried out under general anesthesia. The tumor was encapsulated and could be completely resected. Histological study indicated smooth muscule cell proliferation, especially around capillaries, and the tumor was diagnosed as a vascular leiomyoma.
Our extensive survey of the literature revealed 20 reports of benign myogenic tumor of the larynx (9 cases of simple leiomyoma, 10 of vascular leiomyoma, and 1 of leiomyoblastoma), many of which occurred in the middle and advanced years. The patients consisted of 15 men and 5 women. including 9 male vascualar leiomyoma patients of middle or advanced age. The site of occurrence was supraglottic in 12, glottic in 4 and subglottic in 4; no relation was observed with the histological picture, however. Treatment was surgical, and some cases also required tracheotomy depending on the site of occurrence and morphology.View full abstractDownload PDF (2105K) -

JOURNAL FREE ACCESSThe whole mouth test method was employed for examining changes in gustatory senses due to aging. Participants were 314 male and 356 female healthy volunteers not complaining of taste disorders. Simultaneously, the effects of smoking were examined, comparing 71 male smokers to 142 male non-smokers, ranging from 20 to more than 60 years of age.
A multiple comparison procedure (Tukey-Kramer) was applied to age groups, revealing a significant increase in the threshold with age; high threshold values were observed in the “70s and older” group in comparison to the younger group for all tastes other than the sweet taste. Concerning the differences between males and females, the gustatory thresholds of males were found to be higher than those of females for some in the “20s and older” group and for all tastes other than the sweet taste, whereas the thresholds of males were lower than those of females for all taste qualities in the late teen group.
As to male subjects in whom the effects of smoking could be studied, smokers in their 20s demonstrated a slight rise in the threshold only for the bitter taste.View full abstractDownload PDF (900K) -

JOURNAL FREE ACCESSWe studied the therapeutic efficacy of zinc picolinate in patients with zinc-deficient and idiopathic taste disorders. Efficacy was assessed in a double-blind study. The following findings were obtained:
1. There was a significant difference between the zinc picolinate and placebo groups in the grade of improvement shown by the filter-paper disk method.
2. There was a significant difference between the zinc picolinate and placebo groups in the serum zinc concentration.
3. There was no significant difference between the two groups in the degree of total subjective recovery or the grade of improvement, as shown by in the whole mouth method.
4. We conclude that the administration of zinc picolinate is effective for patients with zincdeficient and idiopathic taste disorders.View full abstractDownload PDF (549K) -

JOURNAL FREE ACCESSElectrogustometric testing was carried out, with one researcher examining the electrogustometric threshold at three sites, in 461 normal cases, by TR-06 (Rion Co.), over a wide range. A multiple comparison procedure (Tukey-Kramer) was applied to age groups, revealing a significant increase in the threshold with advancing age; high threshold values were observed in the “60s and older” group for the chorda tympani nerve area (tongue tip) and the glossopharyngeal nerve area (tongue base), and in the “70s and older” group for the superficial greater petrosal nerve area (soft palate). As to the gender difference in women, a significant drop was observed in the late teens whereas a low tendency in all sites tested was not statistically significant in other age groups. Differences between the right and the left sides were seen in most cases but were within 6dB. As to site differences, the soft palate threshold was higher than those of the tongue tip and the tongue base in all age groups. A significant decrease in the threshold of the tongue tip, as compared to the tongue base, was observed for those in their late teens, whereas minimal differences were noted in the other age groups and at other sites. The soft palate threshold was significantly reduced in smokers in their 30s and 40s as compared with non smokers.View full abstractDownload PDF (1058K) -

JOURNAL FREE ACCESSThere are many patients who complain of abnormal sensations, such as an obstructive sensation, foreign body sensation, difficulty in swallowing, etc., in the throat, which do not have an obvious cause. The causes of such unpleasant symptoms have not been adequately investigated. As one of the potential factors in volved in abnormal sensations in the throat, we considered the existence of subclinical dysphagia. We then performed videofluoroscopic analysis in patients with an abnormal sensation in the throat to examine whether or not there were functional disorders in swallowing.
Videofluoroscopy was performed in 42 subjects, 30 patients with abnormal sensation in the throat and 12 volunteers without swallowing problems. We devised a temporal and spatial analysis system of swallowing using personal computer technology. Videofluoroscopic swallowing sequences during spoon feeding (3-5ml) and drinking from a cup (15-20ml) of liquid barium, were analyzed. The results suggest that two temporal measurements of swallow from videofluoroscopic studies are appropriate for parameter of subclinical dysphagia: the time it takes the bolus to move through pharynx from the point at which the bolus head passes the tongue base until the bolus head extends caudally beyond the piriform sinus while feeding from a spoon (S2), and the time it takes the bolus to move through the upper esophagus from the point at which the bolus head passes the bottom of the piriform sinus until the bolus tail passes the same point while drinking from a cup (C1). Then, we selected C1 and S2 for variables and detect the patients who have subclinical dysphagia with cluster analysis. Forty-two subjects were divided into two groups: those composed of 14 patients (cluster 1), and those composed of 16 patients and 12 controls (cluster 2). We thought 14 patients in cluster 1 would have subclinical dysphagia for the cause of abnormal sensation in the throat.
Temporal and spatial analysis revealed three forms of pharyngeal swallow in cluster 1. In 6 patients, the bolus stall in the valleculae prior to the onset of the pharyngeal swallow. In other 6 patients, the bolus stall in the piriform sinus before swallowing reflex. In the other 2 patients, the bolus moved smoothly but slowly without delay in pharynx.
Our results indicate that a delayed swallowing reflex is the main functional finding in videofluoroscopy in patients with subclinical dysphagia contributing to an abnormal sensatin in the throat.View full abstractDownload PDF (2107K) -
