The anatomic course of recurrent laryngeal nerve, its branch and its function were most significant for laryngeal, thyroid and tracheoesophageal surgery. Furthermore, the vocal cord palsy resulting from multi-etiology was serious complication and resulted in affecting the life quality. So, for the prevention of this complication, the concepts and knowledge about anatomic course and variants are very important. At now, most of anatomic courses and it's function has been identified precisely. But recently, the report about the anastomotic loops of both recurrent laryngeal nerve was published. In this study, we explored three cadevors for identifying the reality of the anastomotic loops between recurrent laryngeal nerves. Finally, we identified the cervicomediastinal anastomosis at tracheoesophageal groove in 2 of 3 cadevors that was confirmed by pathologic finding. This anatomic reliefs related to it's branch are extremely interest, although research is still in its initial phase. Our study will be extended toward histomorphometrical study and progressive electrophysiologic study, and we will be able io gather the largest amount of useful data regarding any possible use of this anatomic entity in future.

Granular cell myoblastoma is a rare muscular origined benign tumor which was first decribed on the vocal cord by Abrikossoff in 1931. Although this lesion is found frequently in the tongue, it has been known to occur in other parts of the oral cavity as well as in the larynx and trachea. It is of considerble clinical importance that this lesion is frequently accompanied by pseundoe-pitheliomatous hyperplasia of the overling mucosa which may easily be confused with carcinoma. We experienced a case of granular cell myoblastoma and report with the consideration of literatures concerning the same disease.

Rhabdomyosarcomas are relatively rare and highly malignant tumors which originated from mesenchymal cells. A 50-year-old man, suffered from hoarseness for 2 months, visited to the Dept. of ENT, Seoul Red Cross Hospital. By indirect laryngoscopic examination, a sessile based whitish polypoid mass (0.5cm$\times$0.3cm) was noted at the one third portion of right true vocal cord. Under general anesthesia, local excision was performed. Biopsy revealed rhabdomyosarcoma of the embryonal type. To our knowledge, only 24 cases of laryngeal rhabdomyosarcoma have been reported in the world literature.

When the laryngeal web is small it rarely produces significant symptomatology. Large webs may produce stridor on both inspration and expiration, as well as hoarseness in various degrees. We have recently experienced with three cases of post-operative anterior glottic web after removal of the papilloma suffering from dyspnea and hoarseness. Layngeal webs with a definite voice problem or stridor should be managed surgically. And so, thyrotomy and a stainless steel keel insertion at the glottic level for repair of laryngeal web was performed. This technique has produced satisfactory result in all cases.

Multiple symmetrical lipomatosis (MSL), also called Madelung's disease, is a rare disorder of unknown etiology and characterized by abnormal accumulation of large subcutaneous fatty masses in neck, shoulder, and upper trunk. MSL has known to predominantly affect middle-aged men with a history of alcoholism. Although the clinical course of MSL is considered to be slowly progressive, in advanced stage, fatty masses in the neck may compress the upper aerodigestive tract, resulting in dyspnea and dysphagia. The treatment of MSL is surgical resection, but radical excision is very difficult and recurrence after surgery is frequent. We report the case of 55-year-old man with long lasting MSL, which caused severe airway obstruction. This patient was admitted with progressive dyspnea and massive accumulation of fat around the vocal cord that was detected on a neck CT scan. This abnormal fatty infiltration in supraglottic region caused upper airway obstruction.

In the past several years the popularity of the motor cycle has produced an increasing incidence of the injuries to the larynx and trachea. Most of all on accidents come to death and survivors to the hospital are rare. Early diagnosis and to keep air way are necessary to initiate proper treatment in injury of upper air way. Meticulous apposition of mucous membrane and reconstitution of laryngeal skeleton are important. We experienced a rare case of 26 year old men with cricothyroidal transection after trauma. On Oct. 17, 1985, the patient struck his neck on baggage frame of truck when dropping from his motor cycle on sudden stop. Emergency tracheal intubation on distal segment of trachea was accomplished by otolaryngologist in a local clinic. He was transferred to our hospital. Exploration 2 hours later revealed complete separation of cricoid cartilage from thyroid cartilage. The recurrent laryngeal nerve could not be identified. Anastomosis of thyroid and cricoid was accomplished and Portex endotracheal tube was inserted as splint for 10 days. No stenosis developed. The air way appeared adequate for moderate physical activity though paramedian fixation of vocal cord paralysis. Postoperative follow-up course has been good after he discharged on POD 14 days.

This study reports our early experience with thoracoscopic division of vascular rings. Three patients were reviewed; their ages at surgery were 25 months, 4 years, and 57 years. All patients were suffering from complete vascular rings involving combinations of the right aortic arch, left ligamentum arteriosum, Kommerell's diverticulum, and retroesophageal left subclavian artery. The median surgical time was 180.5 minutes, and the patients showed immediate recovery. Three complications, namely chylothorax, transient supraventricular tachycardia, and left vocal cord palsy, were observed. Our early experience indicates that thoracoscopic division of a vascular ring may provide early recovery and could be a promising operative choice.

We experienced dfficult airway management in a patient who had Ludwig angina with morbid obesity, dfficulty with mouth opening and neck extension. We planned to perform awake-nasotracheal intubation with fiberoptic bronchoscopy but the patient's condition was not suitable to do this procedure. Thus, we tried fiberoptic nasotracheal intubation under general anesthesia but we experienced difficult airway management due to epistaxis. We tried to use video laryngoscope instead of fiberpotic bronchoscopy but also failed to guide the tube into trachea due to limited mouth opening. We used video laryngoscope to make a view of vocal cord and used fiberoptic bronchoscope as an intubation guide of endotrachedal tube and successfully intubated the patient.

Charcot-Marie-Tooth disease (CMT) is the most common hereditary motor and sensory peripheral neuropathy. CMT is usually classified into two categories based on pathology: demyelinating CMT type 1 (CMT1) and axonal CMT type 2 (CMT2) neuropathy. CMT1 can be distinguished by assessing the median motor nerve conduction velocity as greater than 38 m/s. The main clinical features of axonal CMT2 neuropathy are distal muscle weakness and loss of sensory and areflexia. In addition, they showed unusual clinical features, including delayed development, hearing loss, pyramidal signs, vocal cord paralysis, optic atrophy, and abnormal pupillary reactions. Recently, customized treatments for genetic diseases have been developed, and pregnancy diagnosis can enable the birth of a normal child when the causative gene mutation is found in CMT2. Therefore, accurate diagnosis based on genotype/phenotypic correlations is becoming more important. In this review, we describe the latest findings on the phenotypic characteristics of axonal CMT2 neuropathy. We hope that this review will be useful for clinicians in regard to the diagnosis and treatment of CMT.

"Whiplash"-type injuries are commonly encountered and often cause neck pain, neck stiffness, and headaches. However, these injuries can have rare and poorly recognized complications, such as the development of a prevertebral hematoma leading to acute respiratory failure in the emergency department, followed by severe, life-threatening dysphagia and recurrent aspirations. In the patient described herein, a whiplash injury was accompanied by vocal cord paralysis and dysphonia (vagus nerve), dysgeusia (glossopharyngeal nerve, vagus nerve), and upper esophageal spasm (cricopharyngeal muscle, vagus nerve). It is unlikely that this was a complication of cervical fusion surgery. Instead, a combined stretch-induced lower cranial nerve injury, possibly on the exit of these nerves through the jugular foramen, seems to be a likely, but underappreciated mechanism occurring in rare instances of whiplash injuries.
