Papillary microcarcinomas (PMCs) which are 1.0cm or less in diameter are a specific subgroup of thyroid cancer. As the prevalence of these tumors found in autopsy cases was reported to be 10 to 28.4% in Japan, the necessity of surgical treatment of PMCs has been questioned. However, PMCs are often found in conjunction with advanced metastases in cervical lymph nodes, lung, etc..We reviewed eight cases with PMCs revealed by the presence of cervical metastases over the past 10 years. Five cases were revealed by manifest cervical lymph node metastases. Two of the other three cases were operated on for treatment of metastatic lesions subsequent to other diagnoses, notably a parotid tumor and lateral cervical cyst. The PMCs were revealed in a postoperative histological study of these two cases. The remaining case was discovered incidentally during neck dissection for laryngeal cancer. Preoperative ultrasonography was undertaken in seven cases. Two cases showed multif ocal small high echoic spots without tumors and one case showed no abnormal findings in the thyroid.In all cases, total thyroidectomy, unilateral or bilateral neck dissection and postoperative radioiodine scintigraphy were performed. Multifocal tumors in the thyroid were proven histologically in four cases. In one case, the primary lesion was not found even in a postoperative histological study.In accordance with these observations, PMCs revealed by cervical metastases shoul be treated as advanced thyroid carcinomas.

The three-dimensional imaging used so far has processed digitalized information on the morphology of organs by the computer graphics technique. However, the conventional method has not been used clinically, because the processing of information has been inadequate.We observed the external aperture of the vestibular aqueduct in vivo using three-dimensional imaging by the surface reconstruction method. The width was measured in normal and diseased ears. Significant narrowing was observed in patients with Meniere's disease, while no difference in width was noted between normal subjects and those with chronic otitis media.This technique can be used to examine not only on the vestibular aqueduct but also other structures in the temporal bone. It should be useful in clarifying the pathophysiology of inner ear diseases and also in the surgical treatment.

A 25-year-old male produced a continuous high-pitched tone (6.1KHz, 37.2dB SPL) which was not audible to the patient. He had a sensorineural deafness over 1KHz with a dip of 45dB at 6KHz. The sound was considered to be due to a spontaneous oto-acoustic emission.

昭和52年1月から昭和57年9月までの6年9ヵ月間, 京大病院耳鼻咽喉科を訪れた顔神麻痺患者662名について統計的観察を行い以下の結果が得られた.(1) 顔神麻痺患者は, 外来新患数の1.8%を占めていた.(2) 年度別発生件数では, 各年ともベル麻痺が1番多く, 62.0~80.5%を占め, その他の頻度はまちまちであった.(3) 診断別分類では, ベル麻痺が1番多く, 447例 (67.5%), 以下, ハント症候群59例 (8.9%), 手術損傷性45例 (6.8%), 頭部外傷性45例 (6.8%), 先天性23例 (3.5%), 耳炎性15例 (2.3%), 中枢性6例 (0.9%), 側頭骨外疾患4例 (0.6%), 聴神経腫瘍2例 (0.3%), その他16例 (2.4%) であった.(4) ベル麻痺, ハント症候群における男女の差は著明でなかった.(5) ベル麻痺, ハント症候群とも左側にわずかに多かった.(6) ベル麻痺, ハント症候群の月別発生頻度は, 前者は11月に少なくなっている他は著明な差は見られなかった. 後者も季節的な一定の結論を出すのは困難であった.(7) ベル麻痺, ハント症候群とも青壮年が多く罹患していた.(8) 再発性麻痺は40例あり, 一側反復性麻痺14例, 両側交代性麻痺25例, 両側同時性麻痺1例を含んでいた.(9) ウイルス感染については, 検索を行った73例のうち, 感染ベルは21.3%で, ハント症候群では75%に帯状疱疹ウィルスに感染が認められた.
