Bilateral vocal cord palsy is uncommon but is serious because of airway obstruction. Treatments of bilateral vocal cord palsy are initially tracheotomy, vocal cord lateralization and vocal cord reinnervation. Recently, we experienced nerve-muscle pedicle reinnervation in 3 cases of bilateral vocal cord palsy, so reported it with a review of literature.

The clinical investigation was done in the 42 patients with bilateral vocal cord palsy who visited the otorhinolaryngologic department of the Yongdong Severance Hospital during the 10-year period between August 1986 to August 1996. On the sex and age distribution, the ratio of male to female patients was 2.8 : 1 and the age was evenly distributed and average was 46 years old. Of their chief complaints, dyspnea was the most common symptom. Among the position of the paralyzed vocal cords, paramedian position was most common. The most common causes of the bilateral vocal cord palsy was idiopathic Other causes include iatrogenic, prolonged intubation, head ＆ neck trauma, brain tumor, Myasthenia Gravis, and mediastinitis. Our treament results were as follows. Recovery rate of idiopathic bilateral vocal cord palsy was 77.7% and recovery period after bilateral vocal cord palsy was shortened remarkedly after use with steroid. We performed laser arytenoidectomy in patients with irreversible idiopathic vocal cord palsy, neural injury, and cricoarytenoid joint fixation. Decannualtion was possible to be carried out in 86% of the patients and none of complication except for 1 case of aspiration developed. Thus we concluded that it was meaningful surgical treatment of bilateral vocal cord palsy.

Bilateral vocal cord palsy (BVCP) present a challenging condition which result from various etiologies including iatrogenic recurrent laryngeal nerve injury, progressive neurological disorder, intubation, trauma, tumor and idiopathic cause. Careful history taking, laryngoscopic evaluation, laryngeal EMG, and imaging studies are helpful for providing a precise diagnosis and planning appropriate treatment. BVCP causes airway restriction and not vocal dysfunction. In patients with BVFP, treatment is directed at maximizing the airway, while attempting to limit the negative effects of treatment on vocal function. A variety of surgical procedures are available for mangement of BVCP. The most conservative, limited procedure should be selected initially, and then further surgery and more extensive surgery can be tailored to the patient's airway and voice needs. This review will address the etiology, diagnosis, and managements of BVCP.

The patient suffered cardiac arrest 8 months before presentation. She has been suffering hoarseness and exertional dyspnea and nocturnal stridor. Upon flexible laryngoscopy, her vocal cords showed no motion and fixed in paramedian position. There was no causal finding on neck CT. EMG showed some muscular activity. Under the suspicion of crico arytenoid fixation, we performed suspension laryngoscopy, and found the arytenoid cartilage was fixed with short and stout scar, which was removed with scissors. Just after surgery she regained her voice and respiration.

Relapsing polychondritis is an uncommon disorder of unknown etiology. That involves multisystem characterized by recurrent inflammation, degenerative change of multiple cartilaginous structures. The most common clinical manifestation is an auricular chondritis. Other involving systems are joint, nose, eye, larynx, trachea, aorta, heart and kidney. A 26-year-old man who complained of hoarseness and sore throat was referred to the ENT department from internal medicine department. On initial video-laryngoscopic and radiologic examination, there was no abnormal finding. Treatment with high doses of corticosteroid and methotrexate was not effective. Symptoms were aggrevated with dyspnea. Three months later, on video-laryngoscopic examination, bilateral cord fixation with swelling was noted. The radiologic finding showed subglottic stenosis due to collapse of anterior wall of cricoid cartilage. The condition was managed with tracheotomy. We report a case of relapsing polychondritis involving larynx and trachea with bilateral vocal cord palsy which was managed with tracheotomy.

양측성 성대마비의 수술적 치료는 여러 가지가 알려져 있으나 원인을 알 수 없는 양측성 성대마비인 경우 견갑설골근과 경계제신경을 이용한 신경-근 이식으로 좋은 결과를 얻을 수 있는 것으로 알려져 있다. 저자들은 양측성 성대마비 환자 3례를 신경-근 이식을 이용하여 수술하였기에 보고하는 바이다. (중략)

Although many factors associated with difficult intubation have been known, predictors of difficult mask ventilation are not well known. We experienced a case of nearly complete airway obstruction following usual anesthetic induction which needed various emergency treatments. The patient had a preoperative diagnosis of contact granuloma of right posterior vocal cord and bilateral vocal cord palsy but later was found out as invasive laryngeal cancer. Upon the surgical field of view, both vocal cords were showing significantly thickened and fixated appearance and was considered as in the critical narrowing state with the potential of complete obstruction. Using $C-MAC^{(R)}$ video laryngoscope we were able to see the narrowed vocal cord and choose proper size of endo-tracheal tube. Consequently, intubation was successfully done and operation was conducted. From this case, we have lessons that physicians should examine the patient's airway more carefully in case of laryngeal mass and prepare emergency measures.

Vocal cord paralysis (VCP) is a common complication after thyroidectomy despite the continuity of the recurrent laryngeal nerve (RLN) is preserved. Much efforts have been made into preventing VCP, but few of them focuses on the treatment strategies and prognosis after VCP take place. In this case, patient visited the clinic for papillary thyroid cancer in Rt. thyroid gland without VCP. She underwent total thyroidectomy with central neck dissection. During dissection, Rt main mass was encircling Rt. RLN. To make matters worse, Lt. RLN was severed due to tight attachment with Berry's ligament. After that, intratumoural dissection of Rt. RLN and end to end anastomosis of Lt. RLN were performed with microscopy to preserve the functions of RLNs as much as possible, otherwise permanent bilateral VCPs were inevitable. We report this case, since both vocal cords recovered from VCPs with symmetric, synchronous movements at postoperative follow up.

유육종증은 침범된 기관에 T림프구와 단핵구가 축적되고, 비건락성 상피양세포 육아종이 생기면서 정상 조직의 구조가 파괴되는 원인 불명의 비교적 흔한 만성 질환이다. 저자들은 쉰목소리를 보여 기관지 내시경을 하였으나, 마비된 왼쪽 성대 자체에는 특별한 문제가 없었으며, 컴퓨터 단층촬영과 Gallium-67 스캔에서 비대해진 종격동으로 회귀 후두신경 압박에 의한 임상 양상으로 추측하였고, ACE증가와 피부 병변의 비건락성 육아종을 보였으며 또한 결핵, 진균 등의 침범은 배제할 수 있어 유육종증을 진단하였다. 해외에서는 쉰목소리의 원인으로 유육종증이 진단 된 경우가 종종 보고되고 있으나, 한국에서 드문 것으로 보여 문헌 고찰과 함께 보고하는 바이다.
