  • Because vocal technique is the basis of singing a song beautifully, so this study was undertaken to use the scientific and correct technique in order to get much better musical expressions. Shimadzu X - ray remote control TV system was used for checking the supporting state of diaphragmatic respiration after 5, 10, 15, 20, 25 and 30 sec during phonation in the state of full inhalation between professional singer and non - professional singer. Shimadzu Magnet $nex-{\alpha}$(SMT -50CX/H) was used for examining the scattering state from the resonance of nasal cavity to that of cranial cavity on the basis of diaphragmatic respiration. The results obtained were summerized as follows : 1. The resonance of cranial cavity must be scattered by the energy of diaphragmatic respiration after gathering the foci of the fundamental 5 vowels. 2. while raising the epiglottis, the resonance of nasal cavity must be clearly in order to maintain the resonance of cranial cavity beautifully. 3. We can get musical expressions by maintaining the elasticity of diaphragmatic respiration.

  • An intact male, 3-month-old, Great Pyrenees mountain dog, weighing 7.3 kg with a history of severe hematuria during 2 months was referred. Hematology showed mild leukocytosis. There were no remarkable findings in abdominal radiographs due to ingesta and gas in the gastrointestinal tracts. Ultrasonographs showed bilateral hydronephrosis, bilateral dilated and tortuous ureters, and hyperechoic sludges in the urinary bladder (UB). And a dilated cavity was identified cranial to the UB. Excretory urography and cystography were performed to examine the cause of hydronephrosis and an abnormal cavity cranial to the UB. Bilateral ureters were tortuously dilated and opened into the craniodorsal part of the UB. An abnormal cavity was connected to the UB at the left cranioventral part of the UB. Therefore bilateral ectopic ureters and urachal remnant were diagnosed.

  • Air accumulation in the cranial cavity is referred to as pneumocephalus. Tension pneumocephalus is a neurosurgical emergency that can cause headaches, seizures, reduced consciousness, and even death owing to increased intracranial pressure. We report a case of tension pneumocephalus. The patient underwent a frontal sinusotomy for a mass invading the frontal sinus and nasal cavity. One month later, the patient was admitted to the emergency room with seizures and neurotic symptoms, and computed tomography (CT) revealed tension pneumocephalus with significant gas dilatation of both lateral ventricles. Prompt treatment of the dural defect resulted in the immediate improvement of neurological signs. A CT re-examination 1 week after surgery showed that the pneumocephalus had completely resolved. Tension pneumocephalus should be considered a potential complication in patients with worsening neurological signs after skull base surgery. An accurate diagnosis requires an understanding of imaging features and a high index of suspicion, and immediate intervention is essential.

  • A one-year-old, intact male, 24 kg, mixed breed dog was referred to the Animal Medical Center, Iksan, Chonbuk, Korea for treatment of a gunshot wound to the head. Physical examinations revealed bilateral nasal bleeding and open-mouth breathing. Radiographic examination showed fracture of the right maxilla bone and multiple fractures of the nasal bone. A $1cm{\times}1cm{\times}1.8cm$ region of mineral opacity material was observed in the right-cranial ventralnasal cavity and a $6mm{\times}6mm{\times}9mm$ region of mineral opacity material was present in the left-cranial dorsal-nasal cavity. The surgical procedure involved removal of bone fragments and the lodged bullet as well as the installation of three intraosseous wires. At two weeks after surgery, the patient exhibited no complications and had a good prognosis.

  • A 8 years old male Pomeranian weighing 4 kg was referred because of coughing of 4 months' duration. Heart sounds and cardiac apex beat were showed more intense on the right side. On radiographic views, loss of normal line of the diaphragm, gas-containing intestines and stomach in thoracic cavity, and right displacement of heart were observed. Ultrasonography revealed that liver located adjacent to the heart. Although the dog died due to severe respiratory disorder in surgical procedure, in thoracic and abdominal surgery, a large defect was found in the left and right ventral muscular portion and left central tendon of the diaphragm, extending from the esophageal hiatus to rib. Left and right cranial lobe of liver, small intestines, stomach and spleen were herniated in the thoracic cavity. Because of the size and chronicity of the defect in the diaphragm, closure was impossible with an abdominal muscle graft.

  • Food intake and swallowing are complicated and intriguing series of movements involving voluntary and involuntary activities of cranial and spinal nerves and muscles. They have two most important functions, that is, food passage from the oral cavity to stomach and airway protection. Tongue, buccinators, and hyoid bone and its muscular attachments are anatomic structures for swallowing of special interests. The swallowing process of liquid is commonly divided into oral preparatory, oral propulsive, pharyngeal, and esophageal stages according to the location of the bolus. The movement of the food in the oral cavity and to the oropharynx differs between eating solid food and drinking liquid.

  • Neurilemmoma is a benign, well-encapsulated neurogenic tumor that arises in cranial, peripheral, or autonomic nerves that have nerve sheaths containing schwann cells. From 16 to 45% of all neurilemmoma cases occur in the head and neck region and only about 4% of those cases are found in the nose and paranasal sinuses, but very rarely found in the nasal septum. Recently, we experienced a case of isolated neurilemmoma which arose from the nasal septum of a 30-year-old female patient who complained of nasal obstruction and postnasal drip. The mass was broadly based on the right anterior portion of the nasal septum and confined to the nasal cavity, displacing the lateral wall of the nasal cavity and middle turbinate, laterally and posteriorly, respectively. The tumor mass was completely excised through transnasal endoscopic surgery under general anesthesia. The final pathological diagnosis viewed under a microscope after H&E and anti S-100 protein stain was a benign neurilemmoma in which Antoni A type and B type both existed. This report presents a case of neurilemmoma which arose from the nasal septum with reviews of the clinicopathologic features.

  • Objectives : The purpose of this study is to understand truncus area conception to be explained in the pyobon and geungyul (Root-Stem and Origin-End relationships; PG) of meridian theory as to do the macro organic spatial conception in bio-mechanic system for human body. Methods : The extremity areas and truncus area to be explained in PG theories were classified spatially, and the reason was discussed that human body was classified as the extremities and truncus areas for the people of old times. It was considered the structural characteristics, exercise species and movement characteristics of truncus area in human body also. Results : The truncus area were made of cranium, vertebrae, sternum, ribs, clavicle, scapula, sacrum and the hipbone. It was the hollow structure and classified as cranial cavity, pleural cavity(thoracic cavity) and pelvic cavity. These cavities had mutually organic relationships, and because of cavity structures in the truncus and full structures in extremities would act in different direction about gravity with each other for movements. So it would be estimated that the old peoples had to need to separate the truncus and the extremities. Conclusions : In this study, the truncus area and the extremity areas in the PG of meridian theory could be recognized as the spatial conception of bio-mechanic system in human body. Although this study was the theoretical study not to be proven, it will be used to understand for the meridian theory as basic reference for spatial conception and bio-mechanic system.

  • The first case of intracranial metastases of a cervical intramedullary low-grade astrocytoma without malignant transformation in adult is presented in this report. Seven years ago, a 45 year-old male patient underwent biopsy to confirm pathologic characteristics and received craniocervical radiation and chemotherapy for a grade II astrocytoma in the cervical spinal cord. Two years later, posterior fusion was necessary for progressive kyphosis in the cervical spine. He was well for approximately 7 years after the primary surgery. Two months ago, he presented with partial weakness and incoordination with gait difficulty. MRI Scan demonstrated multiple small lesions in the cerebellar vermis and left hemisphere. After suboccipital craniectomy and posterior cervical exposure, the small masses in the cerebellar vermis and hemispheres were excised to a large extent by guidance of an intraoperative navigation system. The tumor at the cervical and brain lesions was classified as an astrocytoma (WHO grade II). When a patient with low-grade astrocytoma in the spinal cord has new cranial symptoms after surgery, radiaton, and chemotherapy, the possibility of its metastasis should be suspected because it can spread to the intracranial cavity even without malignant transformation as shown in this case.

  • The Functional endoscopic sinus surgery through transnasal approach is a common modality of treatment for disorders of the nasal cavity, paranasal air sinuses as well as cranial cavity. The olfactory fossa (OF) is located along the superior aspect of cribriform plate which varies in shape and depth. This variable measurement of the depth of OF is mostly responsible for greater risk of intracranial infiltration during endoscopic procedures in and around the nasal cavity. The morphology of frontal and ethmoid sinus (ES) vary from simple to complex. This cadaveric study is planned to improve the ability of the otolaryngologist, radiologist to understand the possible morphological variations and plan steps of less invasive "precision surgery" to have a safe and complication free procedures. A total of 37 human head regions were included in the study. For classification of OF, Modified Kero's classification was used. The size, shape and cells of frontal and ES were noted. We found, type II (60.8%) OF was more common followed by type I (29.7%) than type III (9.5%). The shape of frontal sinus was comma shaped (55.4%) followed by oval (18.9%) than irregular (16.2%). Most common two cells type of ES was seen in 50.0% of both anterior and posterior ES. Out of 74 ES, 8.1% of Onodi cells and 14.9% of agger nasi cells were seen.
