Nowadays, microwave ovens are commonly used for cooking. However, the cooking certain food in microwave ovens can be hazardous. It has been reported that the heating eggs in a microwave oven can cause an explosion and injuries. The exploding eggs can cause burn injury of face, neck, eyelid, pharynx and larynx. Direct thermal damage to the larynx after swallowing microwave-heated eggs is rare. The authors report a larynx thermal injury due to microwave-heated eggs and review the cause and the prevention methods of exploding eggs.

Despite the incidence of tuberculosis has been greatly reduced with chemotherpy, it is still a common disease in Korea. The pharyngeal and laryngeal tuberculosis usually result from direct contamination of the laryngeal or pharyngeal mucosa by sputum heavily laden with Mycobacterium tuberculosis, secondary infection from the lungs via lymphatic or hematogenous routes, or a primary affection from inhaled tubercle bacilli. Recently the authors experienced a pharyngolaryngeal tuberculosis and report this case with brief literatures review.

Objectives : The aim of this study was to understand application of Ganhap(干合) theory to human body. Methods : We investigated 5 important sphincters along the alimentary tract (Larynx, Pharynx, Cardia, Pyrolus, Iliocecal portion) comparing with the function of Viscera and Bowels, also with Meridian and collateral theory. Results & Conclusions : We can analyze 5 important sphincters along the alimentary tract into relationship of Ganhap. 1. Larynx are related with the combination of Byeong-Sin(丙辛合). 2. Pharynx are related with the combination of Jeong-Im(丁壬合). 3. The Cardia is related with the combination of Mu-Gyu(戊癸合). 4. The Pyrolus is related with the combination of Gap-Gi(甲己合). 5. Ileocecal portion is related with the combination of Eul-Gyeong(乙庚合).

After esophagectomy, the stomach is used most commonly for the method of reconstruction. However, the stomach may not be large enough to be reached the site of anastomosis when it is above the pharynx. We experienced a double primary cancer of the lower esophagus and the larynx. Total laryngectomy and total esophagectomy were done with cervical pharyngojejunogastrostomy for reconstruction. Free jejunal graft is interposed between the oropharyngeal stump and the stomach is pulled-up. We could restore the alimentary track without tension at the anastomotic site and obtain sufficient blood supply.

Over the last 30 years or so, it has been recognized that neurologic disorders could impair laryngeal function, and that neurogenic etiology could be discerned frequently. This has led collaborations between laryngologists and neurologists and focus on the management of neurogenic dysfunction of the larynx and pharynx, including central and peripheral disorder. The author introduced anatomical structure, nerve distribution and neurophysiology of the larynx for understanding its basic functions. The symptoms, diseases from laryngeal dysfunction and the development of diagnosis and management were also discussed.

Changes in the human voice occur between infancy and old age and reflect a myriad of biological changes that influence the size, shape, and physical properties of the larynx. The human larynx is located near the base of the neck and attached inferiorly to the trachea and opens superiorly into the pharynx. The larynx by the third month of fetal life has the same features recognizable at birth. The fundamental frequency of vocal fold vibration generally becomes higher in early age, lower in middle age, and higher in old age. These decreases in Fo undoubtedly result from a combination of factors, consisting of modest increase in length and mass of the muscle and connective tissues of the vocal fold. But the level of the larynx in the neck may be closely connected with Fo directly, high larynx in related with high pitch and low larynx with low pitch. The purpose of this study is to determine the developmental level difference from child to adult larynx using conventional radiography, and the change of speaking fundamental frequency from second decade to sixth decade.

Having examined the literatures on the terminologies. UlkyuK and Banui, the following results were obtained. 1. since Ul accompanies the symptom of dysphagia. it is thoughr ro indicate the disease and ailment in the larynx and pharynx. and the esphangus. 2. Kuyk is used in the contextof Kyuksak. Kyukjung. Bikyuk. Ulsakamnd Ulkyuk. and since it also includes the meaning of Ul. it is thought that disease and ailment in the esophagus. stomach and duodenum are included in this category. 3. Although Ul and Kyuk are differentiated. since they appear in conjunction with the other clinically. they can be refferred to as Ulkyuk. 4. Banui represents the phenomenon of vomiting. because it is oresent in a bad case of Ulkyuk. it can be seen to be included in Ulkyuk. Thus. Ulkyuk and Banui can be refferred to as one. 5.Although the name of an ailments in oriental medicine and that in the western medicine can not be in perfect match. Ulkyuk is refferred to as ailments in esophagus such as esophagitis. esophageal ulcer, esophageal deverticulum and esophageal cancer. while Banui is refferred to asailments in stomanch and duodenum such as stomach cancer. chtonic spasmic gastritis. it is reasonable to differentiate the two in general. As seen above, since the concept of the terminologies. Ulkyuk and Banui are somewhat different among Oriental medicine doctors. a consensus is needed to come up with terms that all can agree on.

Plasma cell mucositis is a very rare benign disease characterized by dense lymphoplasmacytic infiltration in the submucosa layer. It appears as a reddish ulcer on the mucous membrane or as a cobblestone or nodular mass on the affected mucosa. When it involves the pharynx or larynx, the patient presents with dysphagia, voice change and dyspnea. Clinically, it is important to differentiate with malignant diseases such as extramedullary plasmacytoma, amyloidosis and sarcodosis. Several cases of mucositis in the larynx have been reported in English literature, but none have been reported in Korea. We report a case of plasma cell mucositis in the larynx with a review of literature.

The problem of voice restoration after total laryngectomy has existed ever since Billroth's first total laryngectomy in 1873. Since then, all the efforts to restore the voice was tried to divert the tracheal air to the pharynx to produce voice, which became the tracheo-esophageal shunt voice currently used. With the intact pharyngoesophagus, however, there are two basic options for speech rehabilitation : the artificial larynx and esophageal voice. The artificial larynx is an electrically driven buzzer or a sound transducer and its most common type is placed against a supple point on patient's neck and introduces a mechanical sound into the tissues and air spaces of the neck. This sound, emanating form the mouth, is articulated by the intact structures of the remaining vocal tract as understandable speech. Esophageal voice is a commonly recommended method for alaryngeal speech rehabilitation, which can be successfully done by regurgitating the air stored in the esophagus. Successful esophageal voice is preferable to the artificial larynx but, most patients usually adapt only one of those methods according to their needs and feasibility to learn.

Human pharynx is unique, acting as a complex interchange between the oral cavity and esophagus, and between the nasal cavity and lungs. It is actively involved in the transport of food and liquid, producing the forces that guide that bolus into the upper esophagus and away from the adjacent larynx and lungs. This study intended to develop a biomechanical model of the human pharynx, utilizing Finite Element Method(FEM). Within each model changes in cross sectional intralumenal area were calculated and compared with the area from the computer-generated FE model. Area matching allowed estimation of intraluminal pressure gradients during swallow. The estimated pharyngeal pressure gradient varies from one region to another. The estimated pharyngeal pressure gradients showed different patterns for upper four levels and lower four levels. The contraction velocity for upper four levels is much higher than lower four levels. The higher contraction velocities and pressure gradients in the upper levels are consistent with the bolus velocities required for efficient swallow.
