JOURNAL FREE ACCESSFor the laryngomicrosurgery, many kinds of surgical instruments are used. The instruments frequently employed are forceps, knives, scissors and so on. We emphasize that polyps or nodules must be resected with smaller numbers of surgical manipulations, as simple as possible. For that purpose, we recommend forceps specially designed. One arm of the forceps is straight and fixed, the other can be opened laterally. The vocal fold is pushed down with the straight arm and the vocal fold is reversed upward. Consequently, the polyp or nodule can be observed as a whole.
In this paper, the technique for resection of cysts is mainly demonstrated. They say that the cyst should be removed as a whole. We recommend that the cyst could be removed with newly designed forceps even before complete tearing from the vocal fold. Even if the cyst wall is partially remained, the forceps accomplish good job for resection of remaining wall.View full abstractDownload PDF (8685K) -

JOURNAL FREE ACCESSSince radical treatment is accompanied by regional and extensive tissue resection in advanced inferior gingival carcinoma, head and neck reconstruction is relatively difficult. If a surgical complication such as a fistula develops, the grafted bone-plate may be contaminated by saliva and wound healing impeded by compound factors such as poor blood circulation in the remaining mandibula and surrounding tissues due to inflammation.
Subjects were 50 patients undergoing osseous scirrhous reconstruction for inferior gingival carcinoma from 1986 to 2004. Of the 50 cases, 15 cases had local postoperative complications, with 4 requiring reoperation and the remaining 11, including 2 of flap necrosis, cured conservatively. Cases were classified into group A, with no bloodstream involvement due to bone bloodstreams of reconstruction materials, group B, involving bloodstreams from the periosteum, and group C, with direct nutrient vessel in the bone. Complications occurred in 27% in group C, versus 35% in groups A + B, the difference in incidence being very small. Reoperation was only 3% in group C, Versus 18% in groups A + B. The incidence of complications was 42% for the flap of the latissimus dorsi with ribs versus 29% for the scapular flap. Reoperation was 17% for the latissimum dersi versus 3% for the scapular flap. Infections are this liable to be prolonged. Reflecting on complications in hard reconstruction of the mandibula, we studied surgical technique and matters necessary to make hard reconstruction successful.View full abstractDownload PDF (2844K) -

JOURNAL FREE ACCESSThe tonsils, especially the palatine tonsils sometimes exhibit atypical hypertrophy, which includes papillary hypertrophy and pendulous hypertrophy (pendulous tonsil). These two forms of hypertrophy are known to be identical histologically.
I have observed another type of tonsil hypertrophy of the pharyngeal, palatine, and lingual tonsils, tumor-like hypertrophy.
The histological picture of this type of hypertrophy has also been found to be the same the other types of tonsil hypertrophy. I call this type of tonsil hypertrophy, “tumorous hypertrophy of the tonsil”.View full abstractDownload PDF (4992K) -

JOURNAL FREE ACCESSThe nasal cycle is one of physiological factors of changes in the nasal mucosa. Some investigators have reported that changes in objective measurements of nasal patency are sometimes different from changes in sensation of nasal obstruction in response to antihistamines in nasal allergy patients. This discrepancy may be zssociated with the effect of the nasal cycle.
We compared measurements of the nasal cycle with a portable-type nasal flowmetry device before and after antihistamine therapy in pollinosis patients. The subjects were seven seasonal nasal allergy patients. During non-season and on-season pollen periods, the subjects were instructed to return home with the measuring device and record left and right nasal airflow continuously. The same measurements were made, after 2 weeks of treatment with an antihistamine.
Six of the seven patients had a nasal cycle, and the number of cycles during a 12-hour observation period significantly increased during the pollen season. When we compared peak-to-peak changes in right and left respiratory flow rates, a dynamic change was observed during the pollen dispersal period. Although nasal patency was not improved by antihistamine therapy, the nasal cycle pattern became the same as during the non-dispersal period. The mechanism of the improvement of nasal cycle remains to be determined as to whether the pharmaceutical effect was due to a peripheral action or a direct central action. However, the nasal cycle pattern may be related to the sensation of nasal obstruction. In conclusion, observation of nasal cycles was concluded to be useful for elucidating the pathology of nasal allergy.View full abstractDownload PDF (1436K) -

JOURNAL FREE ACCESSMetastasis of carcinoma to the skeletal muscle is extremely rare. We report a case of squamous cell carcinoma of the gingiva with metastasis to the right calf muscle, together with a review of the literature. A 63-year-old man with squamous cell carcinoma of the gingiva oral cavity reported a tumor in the right lower leg 23 months after treatment for the primary tumor. Histological examination of the leg tumor showed it to be squamous cell carcinoma metastasizing to the right calf muscle. He died of progressive metastatic disease, including lung and bone, seven months after diagnosis. The prognosis associated with skeletal muscle metastasis is thought to be poor, consistent with the fact that it generally occurs as a feature of systemic spread. We should therefore include metastatic disease in the differential diagnosis of any mass in the skeletal muscle, and treatment should be individualized based on symptoms, disease spread, and prognosis.View full abstractDownload PDF (2743K) -
