사람의 성대는 일상회화중 1초에 100∼300번 진동하며 노래를 부를 때에는 100번 이하 또는 1,000번 이상까지 진동하게되므로 우리의 육안으로는 그 자세한 진동상태를 관찰할 수 가 없다. 따라서 이런 경우의 성대 진동상태를 관찰하려면 특수한 검사기기를 사용해야한다. 현재 사용되고 있는 검사법으로는 후두스트로보스코피(laryngostroboscopy), 초고속영화촬영(ultra high speed cinematography), 그로토그라피(glottoraphy) 및 카이모그라피(kymography) 등이 있다. (중략)

보통사람의 성대는 일상회화중 1초에 100∼300번의 진동을 하며 노래를 하는 경우는 1,000번 이상도 진동하게 되므로 우리의 유안으로는 그 자세한 진동상태를 관찰할 수가 없어 특수한 기기를 사용해야만 한다. 현재로서 사용되는 특수기기로는 후두스트로보스코피(laryngostroboscopy), 초고속영화법(ultra high speed photography), 그로토그라피(glottography) 및 카이모그라피(kymography) 등이 있다. 이 중 초고속영화법은 1초에 3,000회 이상의 성대진동을 촬영할 수 있어 연구 및 교육에 대단히 유용한 기기이나 가격이 비싸고 그 data를 분석하는데 시간이 많이 걸려 일반임상검사로서는 부적당하며 그로토그라피는 성대자체를 직접 관찰하는 것이 아니고 그 관측결과를 그래프로 나타내주는 기기로서 에에는 초음파, 광전 및 전기를 이용한 방법등이 있다.

음성질환의 진단을 위하여 사용하는 검사법은 여러가지가 있으며 음성발생의 기전에 근거하여 공기역학적 검사로부터 어음청취검사에 이르기까지 다양하게 시도되고 있다. 이중 성대점막의 진동양상은 간접후두경 만으로는 정확히 관찰하기 어려우므로 후두스트로보스코피, 초고속촬영법, 광전, 전기, 초음파등을 이용한 글로토그라피 및 카이모그라피 등이 사용되고 있는데 임상적으로는 후두스트로보스코피가 가장 널리 사용되어지고 있다. 저자들은 1992년 4월 부터 1993년 3월까지 연세대학교 의과대학 음성언어의학연구소에서 음성검사를 시행하였던 환자들을 대상으로 질환별 스트로보스코피소견의 특징을 파악함으로써 후두질환의 진단 및 치료에 도움을 얻고자 하였다.

Background and Objectives : The vocal fold nodules which were made by excessive contact or vibration of the vocal folds were classified to the soft nodule and the hard nodule in according to the hardness or the duration of nodule. Sometimes laryngologist saw the nodule to be located in different level. Authors thought that each nodule to be located in different level might have the different causes. Therefore we studied to know the relationship between the voicing technique and each vocal fold nodule to be located in different level. Materials and Methods : One-hundred forty nine patients who had the vocal fold nodule were evaluated. Sites and shapes of the vocal fold nodules were investigated using videostroboscopy. Videokymography was also used to scan the center of the vocal fold nodules during phonation and classified to several types. Same procedures were done on normal subject while he simulated the various types of voicing. And we compared the findings between both of them. Three different types of lesion can be distinguished. These are ML group that lesions were located from mid to low, MH group that lesions were located from mid to upper and HL group that lesions were located from lower to upper of the vocal folds. Results : The VKG findings of ML group and situation simulating with hard glottal attack and vocal fry were similar. MH group had a similar VKG findings with situation simulating with whispering or high pitch voicing. HL group had a similar VKG findings with situation simulating with loud voicing. Conclusions : Authors thought that each vocal fold nodule, which had different shapes and located in different level, related with the different types of voicing.

Background and Objectives: Benign vocal fold lesions have shown various voice onset types on phonation, however, they have not been documented yet. We studied to know the relationships between benign vocal fold lesions and voice onset types. Materials and Method: 114 subjects were evaluated by using videokymographic examinations. The subjects were classified into three types: normal, contact, and open types according to the patterns of voice onset types on phonation. Benign vocal fold lesions were investigated and voice onset types were compared between normal and disease groups. Voice parameters were obtained from and compared in all subjects to assess acoustic and aerodynamic factors. Results: The normal type among onset types were more than contact type or open type in both normal and disease groups. Disease group showed many contact and open types when. compared with normal group. Vocal nodule and vocal polyp were showed many normal and contact types, however, sulcus vocalis was almost showed open type among voice onset groups. The values of mean flow rate (MFR) of contact type were significantly higher compared to normal type in disease group (p<0.05). Shimmer of contact type was higher than normal type in diseasegroup, but the difference was not significant (p=0.057). Conclusion: Benign vocal fold lesions were related to the various types of voice onset. The various types of voice onset should be considered when benign vocal fold lesions were examined.
