There have been few large scale surveys of salivary gland tumors, because the salivary gland tumors comprised less than 3 percent of all neoplasms of the head and neck. Also there is a problem that the incidences of specific types of tumors have the variation according to the geographic regions. ]'nother Korean reports about salivary gland tumor, they only treated about 100 cases only. Objectives : The purpose of this study is to identify the frequency and clinical characteristics of salivary gland tumors and to compare with other Korean reports. Materials and Methods : We had performed to analyze 387 cases of salivary gland tumors from 1983 to June 1997, were reviewed in histopathological and clinical aspects. The diagnoses of individual tumors were based on the World Health Organization classification. Tumors were analyzed according to the histologic type site, age and sex. Results : The majority (79.1%) of cases occurred in the major salivary glands and 20.9% in the minor. The parotid gland was the most frequent site with 52.4% and submandibular glands with 26.3%. Benign tumors were 79.3% of the tumors and malignant tmon were 20.7%. The most frequent tumor was pleomorphic adenoma occupied 63.8% of the total and frequency percent of histologic type of 98 malignant tumors showed 35.7% of mucoepidermoid carcinomas, 24.5% of adenoid cystic carcinomas. Overall gender with female predominance with 1 : 1.4 of male to female ratio. The average age of patients was 42.8 years. The most frequent chief complaint was a palpable mass. The duration of the symptom was shorter in the malignant salivary gland tumors (26.7 months) than in the benign salivary gland tumors (38.2 months). Conclusion : Comparing to the previous Korean reports, the present study confirms that the incidence of salivary gland tumor was lower in the parotid gland, and was higher in the submandibular and minor salivary glands.

Background: Laryngeal cancer, the most common malignancy of head and neck, is being detected and treated in earlier and more effectively due to introduction of endoscope, continuous development of radiographic technology, and advancement in new surgical techniques such as laser surgery and conservation laryngeal surgery Objectives To compare the different treatment results for early laryngeal cancer to determine which methos provides the good prognosis. Materials and Methods: Retrospective study was done for 135 patients with early laryngeal squamous cell carcinoma(Stage I or II) who were treated at our institute between 1989 to 1996. There were 105 patients with glottic cancer(Stage I: 68 patients, Stage II:37 Patients) and 30 patients with supraglottic cancer(Stage I: 12 patients, Stage II:18 patients) Initial treatment included radiation therapy for 54 patients, endoscopic laser surgery for 8 patients, laryngofissure and cordectomy for 8 patients, vertical partial laryngectomy for 37 patients, supraglottic laryngecomy for 14 patients and supracricoid laryngectomy for 5 patiens, and total laryngectomy for 9 patients. Results : Salvage treatments, such as total laryngectomy, conservation laryngeal surgery, radiation therapy and neck dissection were performed for initial treatment failure with 9 patients after radiation therapy, 8 patients after conservation laryngeal surgery, 2 patients after endoscopic laser and 3 patients after total laryngectomy. Overall 3-year survival rate for glottic 71 was 92.4%, glottic f 84.3%, supraglottic 7172.7%, and supraglottic f was 63.%%. However, survival rate of the same stage was variable according to the choice of initial treatment. Conclusion New classification of the early laryngeal cancer was necessary and helpful for the choice of the initial treatment.

Aspiration of foreign bodies into the airway is a common problem in spite of efforts to educate the public, and it can be sometimes fatal accidents. We clinically analyzed 101 cases of airway foreign bodies treated in the Department of Otolaryngology-Head and Neck Surgery, Korea University College of Medicine for the past 10 years comparing data with the previous articles. There was male predominance in the occurrence rate, being 72% in the male patients. The peak age was 1 to 3 years of age, and 84.2% was below age of 10. The most common symptom after foreign body aspiration was intractable cough, and obstructive emphysema was most commonly found on the initial chest X-rays. Foreign bodies were mainly located at the right main bronchus and left main bronchus was the next. Peanuts were the most common airway foreign bodies. Ventilating bronchoscopy was performed in the 99 cases and foreign bodies were successfully removed in most cases. There was 2 deaths(2%) resulted from hypoxia after bronchoscopy. The fact that complication rates increase with the duration of the foreign bodies in situ is clear. Therefore, prompt bronchoscopy in patients with suspected airway foreign bodies is essential for lower complication rates.

We have clinico-statically analysed the 235 cases of esophageal foreign body during the period the past 12 years from March InS to December 1996 at the Department of Otolaryngology-Head and Neck Surgery, Korea University College of Medicine, Guro Hospital. The results were as follow : 1) Coin was the most frequent foreign body in the esophagus(172 cases : 73.2%). Bone was the next frequent foreign body (21 cases 8.8%). 2) In sex distribution, 124 cases(52.8%) of patients were the female and 111 cases(47.2%) were the male, so the sex ratio was 1:1.12. 3) In the age distribution, 134 cases(56.9%) were under 5 years of age, coin was the most frequent materials in this age group(111 cases 47.2%). 4) The most common symptom was vomiting(136 cases : 57.9%). The next common symptom was dysphagia and odynophagia was 41 cases(17.4%) 5) The most prevalent site of lodgement was the first narrowing(181 cases : 77.0%), the third narrowing(31 cases : 13.2%) and the second narrowing of esophagus(23 cases 9.8%) in order. 6) In duration of lodgement, 207 cases(88.1%) were lodged for one day. 7) The foreign bodies of esophagus were removed successfully by esophagoscopic procedure under local or general anesthesia. There were 3 cases of complication, one case of esophageal bleeding and two cases of esophageal rupture.

Sudden idiopathic sensorineural hearing loss is a disease that develops within several hours to several days. Its etiology has not yet been verified, but the disturbance of the circulation of blood in the inner ear, inner-ear hydrops, and viral infection are considered possible causes of the disease. This study was conducted to evaluate the effect of Panax ginseng extract, which is known to have a vasodilatory effect, on sudden sensorineural hearing loss. Sixty-nine patients suffering from sudden sensorineural hearing loss were admitted to Korea University Anam Hospital from March to December 2008. They were divided into the experimental (30 ears) and control (39 ears) groups. Ginseng extract (2700㎎/day, 4 weeks) was added to the therapeutic regimen in the experimental group. The effect of ginseng extract therapy was analyzed according to the factors relating to the prognosis. A considerable hearing improvement was documented in both groups (32.2 ㏈ in the experimental group and 25.8 ㏈ in the control group). However, there was little beneficial effect of ginseng extract on additional hearing improvement compared with control. The total recovery rate of the experimental group (80.0%) was better than that of the control group (58.9%), and the experimental group’s high-tone hearing gain at 3 ㎑ (29.7 ㏈) was better than that of the control group (21.7 ㏈). The results of the study suggest that the effects of ginseng therapy tend to be superior to those of the conventional therapy, but the difference between the two is not statistically significant. The hearing gains tend to be in the higher frequencies and may be due to the promotion of cellular differentiation from the supporting cells.
