Background and Objectives : Functional dysphonia is a voice disturbance in the absence of structural or neurologic laryngeal pathology characterized by voluntary misuse of laryngeal muscles. The present report reviews clinical characteristics of 25 patients with functional dysphonia. Materials and Method : We analyzed medical records, perceptual and acoustic analysis of voice samples, aerodynamic studies and laryngoscopy. Results : There was no sex or age predilection. Eighty four percent of patients presented sudden onset of symptoms and 76% had specific events at the onset. Most patients showed breathy or strained voice and various degree of vocal fold insufficiency with supraglottic compensatory contractions. Acoustic analysis revealed non-diagnostic, but mean flow rate was lower than normal in all cases. All patients responded to voice therapy except for 4 patients who were tort to follow up. Mean number of voice therapy sessions required to get responses is 1.9 sessions. Conclusion : We concluded that patients with functional dysphonia responded very well to short-term voice therapy and should be included in differential diagnosis in patients with dysphonia cannot be explained by structural or neurologic etiology.

서론 : 성대구증은 음성장애를 주소로 외래로 찾아오는 환자에서 드물지 않게 볼 수 있으나, 그 병인이 불명확하고 그간의 치료가 만족스럽지 못한 것으로 알려져 간과하기 쉬운 질환이다. 저자들은 이러한 성대구중 환자들의 음성기능 분석을 통하여 향후의 치료효과를 알아보는데 도움이 되고자 하였다. (중략)

연구목적 : 청각장애 아동들은 청각적 피드백의 손실로 인하여 분절적 측면뿐만 아니라 초분절적인 측면도 건청 아동과는 다른 형태를 나타낸다. 석동일(1999)은 청각장애인의 모음 조음의 특성을 고찰한 결과, 저모음의 지속시간이 길며, 고모음의 지속시간이 짧다고 하였다. 또한, 청각장애인들은 자음 산출에 있어서 가시적인 효과가 높은 음소가 낮은 음소에 비해 정조음률이 높다. 따라서, 본 연구의 목적은 청각장애 아동의 자음 중 가장 많이 오조음하는 /s/의 오류 형태에 따라 선.후행하는 고모음 /i/와 저모음 /a/의 지속시간을 비교.연구하는 것이다.

Dysphagia may result from dysfunction of any of the components involved in the complex neuromuscular interaction of swallowing. Hyperfunction of any of the muscles involved in swallowing is a frequent cause of dysphagia. The cricopharyngeus muscle (CPM) is a key component of the upper esophageal sphincter. Cricopharyngeus muscle dysfunction (CPD) refers to the muscle's failure to appropriately and completely relax or expand during deglutition. A variety of disease processes may cause CPD and accurate diagnosis is paramount for appropriate treatment. In appropriately selected patients, intervention at the CPM may yield significant improvement in dysphagia. Interventions include nonsurgical, pharyngoesophageal segment dilatation, botulinum toxin (BoNT) injection, and criccopharyngeal myotomy. Injections of BoNT in patients with CPD have been reported to result in marked relief of dysphagia. Different techniques for instilling BoNT into the CPM have been described. Awake, in-office CPM BoNT injection with electromyography and/or fluoroscopic or ultrasound guidance is performed transcervically or via flexible endoscopy. Operative CPM BoNT injection involves rigid laryngoscopy and esophagoscopy with direct visualization of the CPM. BoNT should be prepared in low-volume, high-concentration dilutions to minimize the potential for undesired diffusion of the toxin. The effects of BoNT occur within weeks of injection and typically last up to 5 or 6 months.

Spasmodic dysphonia is a focal laryngeal dystonia that results in involuntary spasms during speech. The etiology of spasmodic dysphonia is not yet defined, but it is presumed to be a neurological abnormality of central nervous system motor function. The treatment of choice for spasmodic dysphonia is botulinum toxin injection directly at the laryngeal muscles. However botulinum toxin injection requires repeated procedures. Many different kinds of surgical treatments have been introduced but the recurrence rate is still high. So we performed myomectomy with LASER and neurectomy with specially designed electrical surgical knife which can cut recurrent laryngeal nerve branch selectively with its noble curved section. We report a case of a 43-year-old male patient with spasmodic dysphonia treated by thyroarytenoid myoneurectomy.
