편측 성대마비에 의한 부전의 수술적 치료로는 그 동안 테플론주입에 의한성대내측전위술, 제1형 갑상연골성형술, 또는 피열연골내전술 등이 이용되었으며, 성대부전이 심하거나 성대높이에 차이가 있을 때는 제1형 갑상연골성형술 등에 비해 피열연골내전술이 좋은 결과를 보이는 것으로 보고되고 있다 그러나, 성대의 움직임은 있으면서 뒷쪽에 심한 성대부전(posterior glottic chink)을 보이는 경우에는 아직은 특별한 수술적인 방법이 없는 바, 저자들은 갑상선 부분절제술 후에 생긴 양쪽성대의 움직임은 있으면서 성문 뒷쪽에 심한 부전을 보인 발성장애 환자 1례에서 제1형 갑상연골성형술과 동시에 피열연골내전술을 시행하여 좋은 결과를 얻었기에 보고하는 바이다.

Voice is a physical phenomenon, generated by vocal fold and expiratory airflow. Dysphonia should come from abnormal vocal fold and airflow. Occassionally larynx looks normal in show, but it is actually not. There should be undetected structural or functional abnormalities. So when ENT doctors face dysphonia patients who looks normal larynx, should make a diagnosis through close observation. In this review article we present some dysphonia diseases which looks normal larynx. For example vocal fatigue, vocal fold paresis, posterior glottic diastasis, muscle tension dysphonia and psychogenic dysphonia.

Spasmodic dysphonia is a focal dystonia of the larynx and breathy voice is a typical sign of abductor spasmodic dysphonia. A group of patients with abductor spasmodic dysphonia have a number of acoustic characteristics including abnormal fundamental frequency fluctuations and abnormally long word duration. We report a abductor spasmodic dysphonia case have enlongated voice onset time voiceless consonants and breathy voice in wide band spectrogram. The patient have the acoustic characteristics only in telephone speaking at work time. We treated the patient with anticholinergic and anticonvulsant drug and supplementary voice therapy. The breathy voice and enlongated VOT were disappeared after those treatment.

Somewhat less than 100 cases of neurogenic tumors of the larynx are reported in the literature. This is slowly growing tumor and is mostly schwannomas and neurofibromas, and could affect any age group. Since the first description of Von Recklinghausen's disease in 1882, about 20 cases of laryngeal involvement have been reported in the world literature. In this paper two cases of laryngeal neurofibroma will be presented: one congenital laryngeal neurofibroma in a 2-month-old boy, and one large laryngeal neurofibroma in Von Recklinghausen's disease in a 28 year old woman. The importance of conservative surgical procedure is discussed with. case presentation and literature review.

배경 : 변환실성증(conversion aphonia/dysphonia)은 심리적 요인으로 인해 기질적 문제없이 기능적으로 발성장애를 보이는 경우로, 음성치료의 대상이 되는 것으로 알려져 왔다. 하지만 실제 임상의 예가 적어 상기 질환에 대해 진단적 기준 또는 음성 치료의 효과에 대한 보고가 적은 편이다. 본원에서는 지난 3년간(96/7-99/6) 총 5례만이 상기 진단을 받았고, 이들 중 4례에서 음성치료가 시행된 예가 있었다. 목적 : 변환실성증의 발성 양상과 감별기준, 음성치료의 중재 방법 및 효과를 사례를 통해 보고하고자 하였다.

후두격막은 1822년 Fleichman이 호흡곤란과 발성장애를 야기한 례를 최초로 보고하였으며 선천성으로나 후천성으로 발생할 수 있다. 선천성후두격막은 태생 10주경의 후두발생장애로 발생한다고 알려져 있으며 성문부위에서 가장 많이 발견되며 후천성후두격막은 감염, 외상, 수술 및 방사선조사 후 발생한다. 저자들은 최근 1례의 선천성후두격막과 4례의 후천성후두격막환자를 치험하였기에 문헌고찰과 함께 보고하는 바이다.

Post-thyroidectomy dysphonia occurs very frequently. Causes of dysphonia include recurrent laryngeal nerve (RLN) or external branch of superior laryngeal nerve (EBSL) injury, intubation, laryngotracheal fixation and other causes. Patients commonly characterized hoarseness or their voice impairment inability to short or sing and loss of loudness. Although complete recovery can be expected mostly in 3 months without obvious nerve injury, dysphonia lowers patients quality of life. The present review discuss the very kinds of causes of post-thyroidectomy dysphonia.

Functional dysphonia (FD) is a disease entity which includes various voice disorders in the absence of structural or neurologic laryngeal pathology. Muscle tension dysphonia (MTD), psychogenic dysphonia are representative FD with completely different pathogenesis. Therefore there is no standard treatment modality for FD, the first step of treatment of FD is differentiating patient's voice symptoms from other organic voice disorders and other functional voice problems. MTD is a functional voice disorder caused by hyperfunction of intrinsic and extrinsic laryngeal musculature. Symptoms include increased vocal effort, roughness, fatigue and odynophonia. First line for MTD is indirect or direct voice therapy. Unfortunately, many patients with MTD improve with voice therapy alone. For these patients, various modalities tried; lidocaine application, surgical excision of the false vocal folds, and botulinum toxin injection, etc. Botulinum toxin injections are widely used in the field of otolaryngology, especially for spasmodic dysphonia. However, its use in FD or MTD has only been described in few case reports. The aim of this lecture is to evaluate the feasibility of botulinum toxin injection for FD, especially MTD.
