A retrospective review of 158 patients who had microlaryngeal surgery for benign vocal cord disease, at the Department of Otolaryngology, Kang-Nam St. Mary Hospital, over 2-year period from Mar. 1991 to Feb. 1993, was completed. Of 158 patients, 16 patients(10.1%, male 8 & female 8, most common in fifth decade) had concomitant vocal sulcus unilaterally (10) or bilaterally (6). Vocal sulcus was accompanied with 7.5% (7/93) of vocal polyp, 15.8% (6/38) of vocal nodule, 11.1% (1/9) of Reinke's edema and 8.3% (1/12) of vocal cyst. Vocal sulcus located above the associated disease in 13(59.1%), below the disease in 7(31.8%) and in the lesion in 2(9.0%). Vocal sulcus was found mainly on the midportion of the membranous vocal cord and the length was less than half of membranous vocal cord in 16(72.7%), more than half in 6(27.3%). In 12 cases (54.5%), vocal sulcus was deep enough to attach to the vocal ligament. We thought it is important to consider the concomitant vocal sulcus during the microlaryngeal surgery for benign vocal cord disease.

성대의 bowing은 성대근의 위축, 노화, 상후두신경마비, 성대수술후, 성대구 등의 원인에 의하여 발생할 수 있으며, 대부분의 예에서 경도의 애성을 호소할 뿐만 아니라 아직 효과적인 치료법이 없기 때문에 적극적인 치료를 받지 못하고 장기간 애성을 호소하는 경우가 많다. 저자들은 성대의 bowing의 진단 및 치료에 도움을 얻고자 최근 2 년간 애성을 주소로 내원한 환자중 성대의 bowing을 보였던 25례(성대구 3례, 성대위축증 2례)을 대상으로 치료전ㆍ후의 음성기능을 분석하여 문헌고찰과 함께 보고하고자 한다.

성대구는 성대점막 고유층의 일부 결손 또는 위축성 함입으로 유리연이 내함되어 성대궁형(bowing cord)이 형성되기 때문에 발성시 정상점막 파동이 소실되고 성문폐쇄부전을 보이며 그 결과 애성을 초래하게 된다. 이러한 성대의 내함을 교정하기 위하여 구절제술, 성대 상하순(upper and lower lip) 점막의 위치조절 둥이 시행되고 있으나 성대궁형이 교정되지 않아 음성개선에 실패하는 경우가 많다. 저자들은 구절제술 후 성대궁형을 교정할 목적으로 연골막을 포함한 연조직을 성대근 내측으로 삽입하여 음성을 개선하는데 도움을 얻고자 하였다. 이러한 방법으로 음성수술을 시행한 5례의 경험과 그 효과 및 문제점을 문헌고찰과 더불어 보고하고자 한다.

The mucosal bridge of the vocal fold is an arch of mucosa, formed by some portion of the vocal fold mucosa which is detached in various extension and length. The etiology is uncertain but some is related to vocal sulcus. Because it affects the voice with variable impact, it must be differentiated from functional voice disorder. We report a case of a mucosal bridge of vocal fold with a vocal polyp treated by microlaryngeal surgery and voice therapy.

This study evaluated the voice of 68 normal children and 50 children with palatine tonsil and adenoid hypertrophy with MDVP to examine the hypothesis that their mouth breathing makes the vocal folds dry and this condition contributes to lower the level of voice quality. The results showed that children with palatine tonsil and adenoid hypertrophy had statistically significant elevations in Jitt, RAP, PPQ, Shim and APQ parameters, and had the lower level of voice quality. Therefore, the children with palatine tonsil and adenoid hypertrophy need vocal hygiene education.

The Electrophoretic separation in agarose gel on the esterase and acid phosphatase of blood, midgut and silk gland was carried out with 2 original variginal varieties and 7 F$_1$ hybrids. 1. The midgut of larvae fed on mulberry leaves showed one or two more esterase bands than that of larvae fed on artificial diet. 2. The midgut of C 15 larvae being excellently respondent to artificial diet showed one or two more esterase bands than that of larvae being bad respondent to artificial diet. 3. Electrophoretic separation of esterase bands appeared to be greatly different among newly hatched larvae, 1st and 2nd install larvae of F$_1$hybrids. However the difference among the silkworm varieties was not recognized. 4. According to the change in rearing temperature, the number of the active band of midgut esterase was varied. At the temperature of 28$^{\circ}C$ 5 active esterase bands were found. At temperature of 35$^{\circ}C$ 4 bands were noted at 3rd install and 6 or 7 bands at 4th instar. 5. No similar esterase bands conld be found among midgut, blood and silkgland. There are five esterase bands in the midgut, one in blood and three in silkgland. 6. There was rather small difference in acid phosphatase types of midgut and blood according to varieties and rearing temperature. No active band was shown in silkgland. In midgut, there was one acid phosphatase band at 3rd install, two at 4th instar and three at 5th instar. In blood, One active band at 3rd or 4th instar and three bands at 5th inatar were detected.
