The supraglottic subtotal laryngectomy represents a conservation laryngeal procedure in which the upper portion of the larynx is removed without sacrificing the normal functions of the remaining larynx. The basis for this procedure rests in the embryologic derivation and consequent anatomic compartmentalization of the larynx and its lymphatics, which limit tumor spread. This procedure is performed for carcinoma involving the epiglottis and false cords, and can be extended to include carcinomas of the aryepiglottic fold and the anterior and lateral walls of the pyriform sinus and selected lesions involving the vallecula and base of the tongue. Recently the authors has experienced 4 cases of supraglottic cancer, which were performed supraglottic subtotal laryngectomy. One of which was died because of local recurrence, and the remaining cases were successful with satisfactory rehabilitation without local recurrence and impairment of voice and swallowing.

Solitary fibrous tumors are commonly arise in the pleura and less commonly in extrapleural sites. In head and neck area, solitary fibrous tumors can occur in nose, paranasal sinus, soft palate, epiglottis, thyroid, parotid and submandibular gland. To our knowledge, this is the 5th case of solitary fibrous tumor arising from the parotid gland in English literature. We report a case of solitary fibrous tumor occurred in the superficial lobe of right parotid gland which was successfully treated by superficial parotidectomy with preservation of the facial nerve.

Acute epiglottitis is one of the common conditions of upper airway obstructions in children. The clinical course is not only fulminant but possibly fatal, resulting from massive swelling of supraglottic structures especially epiglottis caused by Hemophilus influenzae. This is so because early recognition and careful airway management is always desired. Numerous reports in the literature reveals that a majority of cases occurs mainly in young children under six years of age, however, recent reports of acute epiglottitis in adult is increasing. We present a series of acute epiglottitis in adult and a review of the literature. We also discuss the differences between acute epiglottitis in adult and in children in terms of clinical course, causative organism, management and the results of treatment.

In Korea, small octopus (Octopus minor) and webfoot octopus (Octopus ocellatus) are food items and fatal laryngeal choking due to ingestion of live octopus is not uncommon. We recently encountered two autopsy cases of accidental choking on small octopus and webfoot octopus. Case 1 involved a 58-year-old fisherman who ingested two live webfoot octopuses in his fishing boat and collapsed. He was immediately taken to the hospital but died. During autopsy, one of the webfoot octopuses was found between his pharynx and esophagus; it was obstructing the epiglottis and upper esophagus. His blood alcohol concentration was 0.140%. Case 2 involved a 55-year-old man who ingested an intact body part of a small octopus and was found dead in his house. He had a history of cerebral infarction and angina pectoris. During autopsy, an intact body part of the small octopus was found to be lodged in the laryngeal inlet.

Objective : The authors attempted to evaluate the pattern of the airway narrowing due to prevertebral soft tissue swelling after surgery of the anterior cervical spine and their clinical significances using plain cervical X-ray images. Methods : Twenty-four patients undergoing anterior cervical spine surgery were reviewed from January 2004 to December 2005. Postoperatively, in daily basis, lateral radiograph of the neck was obtained in neutral position. We measured the upper airway diameter above and below the epiglottis level and prevertebral soft tissue diameter every day for a week and finally 2 weeks after surgery using their simple lateral cervical X-ray films. Results : Both airway narrowing and prevertebral soft tissue swelling were maximum in postoperative 2 days, and decreased rapidly in postoperative 7 days. Airway narrowing was aggravated postoperatively but slowly decreased as prevertebral soft tissue swelling diminished. But, the severity of airway narrowing showed no clinical correlations with clinical symptom and radiologic severity. Conclusion : Not all patients who show severe airway narrowing and prevertebral soft tissue swelling on their plain cervical X-ray film complain respiratory insufficiency. But, the patients with undergoing anterior cervical spine surgery should be monitored carefully for respiratory insufficiency, especially during several days following operation because both airway narrowing and prevertebral soft tissue swelling become peak at postoperative 2-3 days.

Background and Objectives : The treatment of supraglottic stenosis remains a challenging problem in the field of otolaryngology due to its association with dyspnea, dysphagia, and frequent recurrence. Any satisfactory treatment is not yet known. The author experienced six cases of supraglottic stenosis and report the successful treatment of five cases by repeated endoscopic laryngeal excision with KTP-532 laser under suspension layngoscopy. Materials and Methods : Six adults who were treated for supraglottic stenosis between March 1994 and December 1998 at the Department of Otoloaryngology-Head and Neck Surgery, Korea University Medical Center were studied retrospectively. The patients were placed under general anesthesia followed by endoscopic laryngeal excision with KTP-532 laser under supension laryngoscopy. The scar tissue and granulation tissue were visualized with an operating microscope, and then removed using KTP-532 laser (15watts, continuous mode). Intraoperative local steroid(Triamcinolone ) was injected in all cases after the stenotic portions were removed. Results : Endoscopic excision was performed in five cases ; among the five cases, cricoid cartilage was concomitantly removed in two cases, and epiglottis was removed in one case. Satisfactory swallowing and airway respiration were possible in all five patients who underwent endoscopic widening. Conclusion : The treatment of supraglottic stenosis is different from that of tracheal or glottic stenosis in that supraglottic stenosis is mainly developed in membraneous form. Repeated laser excision and local steroid injection under suspension laryngoscopy is an effective and recommend able method for the treatment of supraglottic stenosis.

A 20-day-old female Diprosopia in Holstein calf was observsd macroscopically and radiographically. Anterior head duplication(Diprosopia) was observed and all structures caudal to it were normal. She had two muzzles, three eyes, two ears and two tongues. The tongues were joined at their base just posterior and had one hyoid bone. Schistognathia and cleft lips were also observed in the lower jaws. She had an oral cavity, single epiglottis and a laryngeal cavity communicated with one trachea. The cerebral hemispheres were duplicated and fused together in the caudal region. The olfactory and optic nerves were duplicated. The incisive, nasal, pterygoid, parietal, ethmoid bones and vomer were duplicated, respectively. The skull of Diprosopia was shared by an occipital bone. The mandibules, palatines and sphenoid bones were duplicated incompletely. Three orbits and two fontanelles were observed. The medial lacrimal bones and maxillae were duplicated incompletely and fused with each other, respectively. Cleft palates were observed. Medial mandibular mass which was fused together and was duplicated incompletely at the part of its cranial, was shown synchondrosis with the left mandible, but not with the right.

Objective: The efficacy of mandibular advancement devices (MADs) in the treatment of obstructive sleep apnea (OSA) ranges between 42% and 65%. However, it is still unclear which predictive factors can be used to select suitable patients for MAD treatment. This study aimed to systematically review the literature on the predictive value of cephalometric analysis for MAD treatment outcomes in adult OSA patients. Methods: The MEDLINE, Google Scholar, Scopus, and Cochrane Library databases were searched through December 2014. Reference lists from the retrieved publications were also examined. English language studies published in international peer-reviewed journals concerning the predictive value of cephalometric analysis for MAD treatment outcome were considered for inclusion. Two review authors independently assessed eligibility, extracted data, and ascertained the quality of the studies. Results: Fifteen eligible studies were identified. Most of the skeletal, dental, and soft tissue cephalometric measurements examined were widely recognized as not prognostic for MAD treatment outcome; however, controversial and limited data were found on the predictive role of certain cephalometric measurements including cranial base angle, mandibular plane angle, hyoid to mandibular plane distance, posterior nasal spine to soft-palate tip distance, anterior nasal spine to epiglottis base distance, and tongue/oral cross sectional area ratio thus justifying additional studies on these parameters. Conclusions: Currently available evidence is inadequate for identification of cephalometric parameters capable of reliably discriminating between poor and good responders to MAD treatment. To guide further research, methodological weaknesses of the currently available studies were highlighted and possible reasons for their discordant results were analyzed.

A Literature study on the language disturbance, the results are as follows; 1. Utterance was closely concerned not only the vocal organs(pharynx, larynx, epiglottis, lips, tongue, vocal cord etc,) but also five viscera{especially heart, lung, kidney etc.) in The Yellow Emperor's Canon of Internal Medicine. It is very like the vocal mechanism in Medical science. 2. In the language disturbance, It is classified with dysarthria and dysphasia in Medical science. But in Oriental medicine, it is expressed the language disturbance as coma-speech lessness, stiff tongue-speechlessness, frightening-speechlessness etc. Especially in Oriental medicine, Non-utterance is called aphasia in literature study. 3. In the concern of the language disturbance and five viscera, $Heart{\cdot}Lung{\cdot}Kidney$ are counted of first importence. In differential diagnosis, It is divided sthenia-syndrome and asthenia-syndrome. Sthenia-syndrome is classified with wind-cold, fire-evil, adverseness of vital energy, stagnation of phlegm, is easy to cure. Asthenia-syndrome is classified with sexual desire, anxiety-meditation, fear, is hard to cure. 4. The pathogenesis of dysphasia originated from two factors; The first internal damages are consumption of body fluid caused by lung-dryness and yin-dificiency of lung & kidney. The second disease caused by exogenous evjls is sluggishness of lung-energy. 5. In many using points of acupuncture of the language disturbance, the order is LI-4(合谷), H-7(神門), K-l(湧泉), L-3(太衝), K-3(太谿), S-6(三陰交), H-5(通里), G-15(아門), C-23(廉泉), S-40(豊降), K-6(照海), L-7(列缺), S-36(足三里) etc.

Cancer of the larynx is the most common malignant neoplasm of head and neck and has a generally favorable prognosis. But its incidences of lymph node metastasis and recurrence depend on the primary site of lesion. Especially, supraglottic carcinoma tends to involve the cervical lymph node with easy. We have analyzed retrospectively 49 cases of supraglottic carcinoma treated surgically with or without radiotherapy from March 1986 to February 1992 at the department of otolaryngology, Pusan National University Hospital to find out the incidence of ipsilateral and contralateral lymph node metastasis and to establish the indication of neck dissection followed by T stage. The incidence to the ispilateral and contralateral cervical lymph node metastasis in patients with lateral (aryepiglottic fold) lesions is higher than that in those with midline (epiglottis) lesion. And average incidence of isplateral lymph node metastasis was 51.0% regardless of T stage. Therefore routine neck dissection should be considered in surgical treatment of supraglottic carcinoma, especially, over T2 stage.
