Abstract PDF: As economical and social status are getting better, many ordinary people are interested in well being and leisure sports, the populations enjoying SCUBA diving are increasing recently. The medical problems from SCUBA diving are also increasing. To provide diving knowledge to the medical Drs. for prevention of barotrauma from SCUBA diving and to provide medical knowledge to SCUBA divers for safer diving, author reviews barotrauma of the human body from SCUBA diving. Review includes diving physics, mechanism, clinical manifestations and prevention of barotrama. Pulmonary barotrauma manifests as pulmonary tissue damage, pneumothorax, mediastinal emphysema with or without arterial gas embolism. Arterial gas embolism is one of the most serious and urgent medical problem from SCUBA diving and it need immediate recompression treatment. Barotrauma in the middle ear is the most common medical problem from SCUBA diving, it manifests as Eustachian tube salpingitis, otitis media with effusion. Inner ear barotrauma may lead permanent sensorineural hearing loss. Barotruma also can be occurred in mask,1)teeth, dry suit, and gastrointestinal tract. Prevention of barotrauma is more important than treatment. Prevention of barotrauma is up to divers, diving instructors and medical Drs. Divers and diving instructors should follow guidelines in diving fitness test, keep physical state always to fit to dive, keep diving skills as sharp and keep physical ability to adjust changeable ocean environment. Medical Drs. are responsible to their decision of medical fitness test, so they should know about diving physic, diving physiology and recent guidelines about medical fitness to dive.

Abstract PDF: BACKGROUND
Chronic paranasal sinusitis is one of the most common disease in the otorhinolaryngologic field. Endoscopic sinus surgery is treatment of choice in chronic paranasal sinusitis. The aim of this study was to evaluate objective and subjective treatment outcomes of endoscopic sinus surgery in adult chronic paranasal sinusitis with or without polyp. MATERIALS AND METHODS: We reviewed 84 adult patients underwent endoscopic sinus surgery by one surgeon from June 1999 to June 2000, prospectively. We analyzed preoperative and postoperative subjective symptom scores and acoustic rhinometric results. RESULTS: Fifty cases were male and thirty four cases female. The average age was of 33 year-old (range: 17 to 66 years). There was significantly improvement of symptom scores in postoperative 3 months and 6 months compared with preoperative symptom scores. There was significantly increased postoperative total volume of nasal cavity. When we compared high score group with low score group, there was statistically significant improvement of symptom scores between preoperative stage and postoperative 3 months in radiologic grading group. CONCLUSIONS: Endoscopic sinus surgery is considered to be effective for the treatment of chronic paranasal sinusitis. It seems to be helpful to employ subjective symptom score system and objective total volume change of nasal cavity through acoustic rhinometric test to analyze effectiveness of endoscopic sinus surgery. In this study, the most important preoperative factor of sinus surgery outcomes is radiologic grading system.

Abstract PDF: BACKGROUND
Septoplasty with turbinate surgery is common surgical treatment in patients with septal deviation and chronic hypertrophic rhinitis. The aim of this study was to evaluation objective outcomes of septoplasty with turbinate surgery by analysis of subjective symptom score with objective acoustic rhinometric test before and after surgery, prospectively. MATERIALS AND METHODS: We reviewed 45 adult patients which were done septoplasty with bilateral turbinectomy or turbinoplasty and followed up at least 3 months by one rhinologist from November 1999 to April 2000, prospectively. We analyzed subjective symptom score, minimal cross-sectional area (MCA), C-notch cross-sectional area, and total volume of both nasal cavity before and after surgery. Correlation test was studied between symptom improvement and acoustic rhinometric results. RESULTS: Twenty nine cases were male and sixteen cases female. The average age was 26.9 year-old (range: 17 to 57 years). There was significantly improvement of symptom score in postoperative 3 months (p<0.05). There was significantly increased C-notch cross-sectional area and total volume in postoperative 3 months. Symptoms improvement were associated with acoustic rhinometric profiles, but, there was not significantly correlation. CONCLUSION: Septoplasty with turbinate surgery is considered to be effective for nasal obstruction in patients with septal deviation and turbinate hypertrophy. Acoustic rhinometric test is favorable objective test for evaluation of symptom improvement after septal surgery.

Abstract PDF: As public awareness of the various warning signs of malignancy increases, so does the concern evoked by the self identified finding of mass in the head and neck area. Not all the palpable masses are always significantly abnormal, but any nontender mass especially to the adult is significant enough to warrant further full investigation and follow up, the object of which should be to determine the possibility of malignancy and urgency of treatment. Approach to the diagnosis of the neck mass is so important in that it affects decision regarding further evaluation would lead to the determination of the most efficacious mode of therapy, eventually to the good prognosis. So, it should be emphasized that approach to the diagnosis of neck mass should be planned, systematic and thorough, this begins with the taking careful history following performance of complete examination of the head and neck especially to the nasopharynx, tongue base, pyriform sinus, palatine tonsil and larynx. Then a number of laboratory and radiologic studies are available, following triple endoscopy under general anesthesia and blind biopsy if needed. The most important rule to keep is that any biopsy procedures should be delayed to the last modality of effort to the diagnosis and if it should be done, under the plan of radical neck dissection.

A Case of Nasopharyngeal Angiofibroma.: Kei Won Song, Seok Keun Yoon, Young Sik Park; Yeungnam Univ J Med. 1984;1(1):191-197. Published online December 31, 1984; DOI: https://doi.org/10.12701/yujm.1984.1.1.191

Abstract PDF: Nasopharyngeal angiofibroma is a relatively rare, but is a well known tumor that occurs almost in male, most frequently during the adolescent stage. Its character is histologically benign but clinically malignant because of locally invasive character to the adjascent structures, massive bleeding tendency during surgical procedure and high recurrence rate after treatment. Recently many advancements diagnostic method and surgical technique has reached satisfactory result in treating this difficult tumor. The authors present a case of nasopharyngeal angiofibroma in 16 years old male patient, who was received surgical removal of the tumor through the transpalatal approach after full diagnostic evaluation and preoperative hormonal therapy.
