The presbyphonia is a combination of physiological and structural changes due to aging of the larynx in elderly patients with voice problems. Some of these changes are inevitable, while others may be avoidable or reversible. The fatigue of phonation is the most common clinical symptom of the aging voice. The voice problems with aging are produced from variable causes including the organic lesions of the larynx. It is essential that the curers understand physiologic and pathologic changes of aging voice for minimizing glottal incompetence and improving vocal performance and quality of life of the elderly.

Venous angioma is a congenital disease of vascular malformation, which is a mass like lesion consisted of dilated medullary veins. It is generally a silent lesion since it is found in normal brain tissues and tends to have low blood flow and pressure. The venous angioma could be diagnosed with magnetic resonance imaging and angiography, but most of them are incidentally diagnosed, because it is usually asymptomatic. The patients with venous angioma have nonspecific symptoms, such as headache, nausea and vomiting, seizures, progressive neurological deficit and hemorrhage. In particular, the venous angioma in cerebellum could cause hearing disturbance, tinnitus and dizziness. We report a case of venous angioma in cerebellum that had been mistaken for peripheral vestibulopathy in a patient complaining of dizziness.

Objectives. Antioxidative enzyme efficiency changes in some organs with age. However, no study has been conducted on age-related antioxidant enzyme changes in tongue. In the present study, the authors investigated the activities of four antioxidative enzymes and their protein expressions in the tongues of young and old Fischer 344 rats. Methods. Age-dependent changes in the enzyme activities of total superoxide dismutase (SOD), Mn-SOD, Cu/Zn-SOD, catalase (CAT), and glutathione peroxidase (GPx) were determined using chemical kits, and the protein expressions levels of these enzymes by Western blotting. The study was conducted using rats aged 7 months (the young group, n=8) and 22 months (the old group, n=8). Results. Total SOD, Cu/Zn-SOD, and GPx activities in the tongues of old rats were lower than in young rats, and similarly, corresponding protein expressions were downregulated in old rats. On the other hand, although the protein expressions of Mn-SOD and CAT were lower in old rats, their enzyme activities were not. Conclusion. The results of this study provide a possible mechanism for the tongue aging process, as in old Fischer 344 rats the antioxidant defense system was diminished with respect to enzyme activity levels and protein abundances.

Colon Interposition via the Retrosternal Approach without Enlargement of the Thoracic Inlet for the Management of Esophageal Stricture

백민관,우주현,한승욱,김동영 대한이비인후과학회 2014 대한이비인후과학회지 두경부외과학 Vol.57 No.11

Background and Objectives To report our experience of colon interposition without thoracic inlet widening for the management of esophageal stricture. Subjects and Method Between 2005 and 2012, five patients underwent esophageal replacement using colon graft. Clinical data, such as surgical techniques including thoracic inlet widening, surgical outcomes, and patient’s age and gender were retrospectively analyzed. The follow-up period ranged from 10 months to 5 years. Results All five patients had corrosive esophageal stricture and underwent colon interposition without thoracic inlet widening; four underwent pharyngocologastrostomy and one total laryngopharyngectomy and pharyngocologastrostomy. No major complications, such as aspiration, dysphagia, reflux, or swallowing disorder developed during the postoperative long term follow-up. Conclusion A colon graft without enlargement of the thoracic inlet is an excellent esophageal substitute for patients with an esophageal corrosive stricture. Further surgical experience and more long-term follow-up data are required to produce more precise and statistically meaningful results. Korean J Otorhinolaryngol-Head Neck Surg 2014;57(11):769-73

성서의 구석구석에 흐르는 주요 테마이다. 「복되어라. 평화를 위하여 일하는 사람들 하늘 나라가 그들의 것이니」 예수그리스도가 복음을 선포할 때 제 일성으로 발한 말씀이다. 「하늘 높은 곳에는 하느님께 영광, 땅에서는 선의의 사람들에게 평화!」 예수 그리스도가 탄생할 때에 하늘의 천사들이 착한 목동들에게 전한 말로서 예수 그리스도의 복음 내용 전체를 요약한 기쁜 소식이다. To investigate the impact that the river development effects the river ecosystem, plants ecosystem and structure in Muhanchun and Goggyochun were surveyed. Muhanchun maintains the sound ecosystem. It has sufficient capacity for recreation-activities on the river. The reason is that a hydrophyte absorbs nutrients from the stream and the river ecosystem maintains sound. Number of hydrophyte increase from upstream going forward to downstream. In the upstream various woody plants and hydrophyte appeared. But at midstream, which is the developed area, naturalized plants dominate such as Bidens frondosa, Panicum dichotomiflorum etc. To manage the creek ecologically, hydrophytes should be introduced in partly, for natural purification after rehabilitation of the riverside, and steadily monitoring is demanded.

두경부암 환자에서 기도 흡인의 예방과 치료를 위한 수술 전략

Postoperative airway aspiration is not uncommon in patients with head and neck cancer. Airway aspiration has serious consequences, such as swallowing disorders, nutrition-related health problem, or reducing the quality of life due to maintenance of tracheal or nasogastric tubes. The postoperative oropharyngeal defect due to the surgery may interfere with normal swallowing reflex, or the laryngeal dysfunction caused by radiation therapy may cause severe airway aspiration, which may lead to complications such as dyspnea and pneumonia. Complete removal of the disease is also important in the treatment of head and neck cancer, but it is necessary to select a method to avoid and predict the occurrence of airway aspiration according to the treatment method. The most important factor to prevent airway aspiration after surgery is to preserve the proper volume of the oropharynx and to preserve at least one of the cricoarytenoid joint function. It is also the most effective way to reduce additional complications by seeking appropriate surgical treatment according to airway aspiration status. The purpose of this study is to review the operative methods that can induce airway aspiration and consider the prevention and treatment strategy through review of the literature.

A Pilot Randomized Comparative Study of Two Diathermy Power Settings for Monopolar Microdissection and Bipolar Hemostasis during Tonsillectomy

백민관,김영생,최성호,우주현,이주형,김동영 대한이비인후과학회 2016 대한이비인후과학회지 두경부외과학 Vol.59 No.12

Background and Objectives Optimal electrical power required for diathermy during tonsillectomy has not been determined. The aim of this pilot study was to evaluate and compare surgical outcomes of using diathermy power settings at 15 watts (W) and 25W for monopolar microdissection and bipolar hemostasis during tonsillectomy. Subjects and Method This prospective, single-center, single-blind, randomized study was conducted on 92 patients who underwent 15W or 25W monopolar microdissection and bipolar hemostasis for tonsillectomy. Operation times, post-operative pain severities, and rates of hemorrhage were compared between the 15W and 25W groups. Results The 92 patients were randomized equally into two study groups. The mean operation duration for the 15W group was significantly longer than in the 25W group (18.5±6.11 versus 13.4±6.04 minutes, p<0.01). The rate of minimal hemorrhage (defined as an episode of bleeding not significant enough for hospital visitation) for the 15W group was significantly higher than for the 25W group (41.3% versus 20.5%, p<0.05). No significant intergroup difference was observed between the rates of primary or secondary hemorrhage or postoperative pain scores. Conclusion Twenty-five watt monopolar microdissection and bipolar hemostasis for tonsillectomy had a shorter mean operation time and a lower post-operative minimal hemorrhage rate than 15W monopolar microdissection and bipolar hemostasis.
