성대 운동 장애는 신경, 근육 병변 및 추두 관절 고정 등의 원인으로 발생한다. 후두 근전도 검사는 후두 및 음성 생리, 언어 과학의 운동 기능학적 연구, 그리고 임상적으로는 신경, 근육 병변의 진단 및 예후 판정에 이용된다. 특히 양측 성대운동 장애시 이학적 검사만으로는 신경 병변 및 관절 고정의 감별 진단에 어려움이 많아 근전도 및 신경 전도 검사를 이용한 객관적 검사가 필수적으로 요구된다. (중략)

Viewing the larynx as a part of a thorough physical examination has been universally recommended but yet largely ignored. To see the larynx in its hidden anatomic position, it has been necessary to use an angled laryngeal mirror and an indirect light source, a technique requiring training, artistry and patience. We explored the concept of using a suitable right angle endoscopic laryngoscope as a tool in the out patient department, to replace the unused mirror, in a series of trials during 5 years. The whole procedure takes approximately one minute. It is simple, requires no anesthesia and the larynx and its surrounding structures clearly into view. We were able to record by Camera film and compare with before and after treatment. So we report them with literature review.

배경 : 양성성대질환에 대한 기저막영역과 성대고유층에 대한 연구를 통해서 양성성대질환의 조직병리학적 특성이 밝혀지고 있으며, 질환발생과 관련된 병인과 병태가 밝혀지고 있다. 목적 : 양성성대질환의 병리학적 특성에 맞게 후두미세수술시 성대 고유층 최상층을 최대한 보호하고 병변부위만을 제거할 수 있는 성대점막하주입술의 유용성을 알아보고자 하였다. (중략)

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.

소리란 인간만이 가지는 특유한 발성구조에 의해 생성되는 음으로서 주로 언어소통을 목적으로 발성된다. 소리의 생성은 일정한 성문하압과 성대의 긴장 및 내전운동이 형성되면 공기가 성대를 통과하면서 성대가 진동하여 발생되며 발성된 음은 후두, 인두 구강등의 발성기관에서 공명되고 증폭되므로서 특이한 음색을 가진 소리로 발생되는 것이다. 그 중에서 노래소리란 이러한 발성기관의 종합적이고 이상적인 조화에 의해 발생되는 소리의 극치이다. 그러나 이러한 발성기관이 이상적으로 조화되지 않을 경우 소리의 변화 및 성대에 병변이 초래되어 치료를 요하는 경우도 있다.

Microscopic surgery of the larynx normally have a low recurrence rate. However, once they do recur, it is uneasy to manage recurrent diseases. Recurrence is often the result of inappropriate postoperative care and voice management. Out of the 764 patients operated for benign inflammatory laryngeal diseases, we have conducted a clinical analysis of 54 cases who have had at least one episode of recurrence after the initial treatment with laryngomicrosurgery (7.1% of recurrence rate). High risk groups for recurrence were determined, and they were related to cigarette smoking, alcohol intake, laryngopharyngeal reflux. From our experience and literature review, we conclude that pre- and postoperative patient education concerning these risk factors and voice usage Is of critical need to prevent recurrence of inflammatory laryngeal lesions after laryngomicrosurgery.

There are no standard consensus about treatment results and prognostic factors based on randomized trials for benign vocal fold lesion. Currently, voice therapy is the treatment of choice for vocal nodules, and laryngomicroscopic surgery is for vocal polyps. There are no strong evidences to support it, based on randomized controlled trials, But, it's just a consensus among laryngologist. Considering the pathophysiology of benign vocal cord lesions, cognitive behavioral therapy that corrects the patient's bad voice habits and improves their vocal hygiene could be most important factor for treatment outcomes.

말소리가 만들어지는 과정 중에서 성대에서 성대음이 만들어지는 과정이 가장 핵심적인 과정이라고 할 수 있다. 이때의 성대의 진동을 관찰할 수 있는 방법은 1) 초고속 영화 촬영(Ultra-speed cinematography), 2) 스트로보스코피(Stroboscopy), 3) 성문파형검사(Glottography) 등이 사용되어 왔다. 1)은 고가의 장비이며 분석도 어려워서 아주 극소수의 연구기관에서만 부분적으로 사용되어 왔고, 2)와 3)은 임상에서 그리고 연구실에서 널리 사용되어 왔다. 스트로보스코피의 영상을 비디오로 녹화하는 장비는 이제는 이비인후과 영역에서 웬만한 종합병원급 의료기관 이라면 거의 필수적인 장비로 자리잡고 있다 그만큼 성대의 미세한 병변에 대한 진단적 가치가 높다고 할 수 있겠다. 스트로보스코피는 끊어져서 발생되는 제논 광선이 내시경을 통하여 성대에 전해지고, 성대의 실제의 진동 보다. 아주 느리게 움직이는 것 같은 일종의 허상이 화면에 나타나고 이를 비디오시스템으로 저장하여 관찰하는 것이다(Fig. 1, 2).

Background and Objectives : Classical singers are capable of masking abnormalities due to their high level of training and may present with apparent technical deficits rather than with obvious dysfunction. Therefore, some variations from expected normal laryngeal behavior may be present in trained classical singers. Consequently it is important for otolaryngologist to obtain a baseline assessment of their laryngeal function. Materials and Methods : Acoustic measurement including strobovideolaryngoscopy from 50 classically trained singers was done for this study, which was compared with the data from 20 untrained adults. Results and Conclusion : This study showed that 50-healthy asymptomatic classical singers revealed an incidence of 50% abnormal strobovideolaryngoscopic findings, but their acoustic data was within normal limit despite the abnormal laryngeal findings. Therefore the author recommends that the classical singers need objective voice analysis and their baseline data should be used for the accurate diagnosis of the cause of voice dysfunction In classical singer whose baseline laryngeal behavior may be unusual.
