Over a 12 months period, we treated 2 cases with discrete subaortic stenosis caused by membranous band. In one patient, who was 19 years old woman, the echocardiograms showed the discrete membrane and idiopathic hypertrophic subaortic stenosis [IHSS . She underwent transaortic myotomy and mymectomy simultaneously band resection. Other case of 11 year old boy with discrete subaortic stenosis only underwent membrane resection. Both patients had an uneventful hospital course, but 19 year old woman showed remained pressure gradient in follow up echocardiograms.

Recently we experienced one, case of epiphrenic esophageal diverticulum of a 50 - year - old female patient who had complained heaviness in her chest after meals and occasional dysphagia for one year. Preoperative barium study showed a large epiphrenic esophageal diverticulum at about 7cm above the diaphragm which protruded to the right side of the mid thorax. On the operation field, epiphrenic esophageal diverticulum, measuring 5x 6x3cm in size, was noted. Diverticulectomy and extended myotomy was performed and the postoperative course was uneventful.

Extramucosal esophagomyotomy by thoracotomy, first described by Heller in 1913 was the principal therapy for achalasia. Recently however, video-assisted thoracoscopic surgery has been implied in esophageal surgery, and we have experienced 23 year old male patient with dysphagia and was diagnosed as achalasia who underwent thoracoscopic esophagomyotomy. The esophagogram showed typical bird beak appearance and the lower esophageal sphincter pressure was increased to 35 mmHg. Thoracoscopic surgery was done twice due to incomplete myotomy in first operation and the patient was released of dysphagia in the second operation.

Total laryngectomy is the most useful procedure tor advanced laryngopharyngeal cancer, but it remains the major problem such as loss of voice. Voice restoration is essential for every patients who undergo a total laryngectomy. Ideal voice rehabilitation methods can resolve three factors. First, every laryngectomee can produce voice sufficient for communication, second every patient should be allowed to use both hands freely during phonation, and last, the voice restoration methods should be easy and safe without complication during and after treatment. Among various voice rehabilitation procedures during or after total laryngectomy, it can be divided electronic and pneumatic methods. In pneumatic methods, there are also divided both pulmonary air and non-pulmonary air methods. The non-pulmonary air methods include esophageal speech, buccal speech, and pharyngeal speech. Pulmonary air methods are divided into surgical and non-surgical such as pneumatic speech aid. In the surgical methods, there are neoglottic operation, tracheopharyngeal shunt, and tracheopharyngeal shunt operations. Recently, tracheoesophageal shunt with or without prosthesis are being recognized the most effective method. Blom-Singer low pressure prosthesis, Panje button, and Provox are well known types of prosthesis in the tracheoesophageal shunt operation. Amatsu method is a kind of famous tracheoesophageal shunt method without using prosthesis. Authors tried to review the published articles for evaluation of effectiveness and problems of tracheoesophageal shunt operation with or without prosthesis. In conclusion, indwelling type of prosthesis and pharyngeal myotomy and plexus neurectomy are recommended for higher success rate during tracheoesophageal puncture procedure. More over, Amatsu method is also one of the recommended voice rehabilitation procedure during total laryngectomy. In this situation, pharyngeal myotomy and plexus neurectomy may be helpful for better fluent communication.

A 23-y-o male patient was suffered from intermittent fainting and dyspnea on exertion [NYHA Class IIIIV]. 2-D - Echocardiogram and cardiac catheterization with cineangiogram showed typical IHSS findings those were asymmetrical septal hypertrophy [ASH], systolic anterior motion of anterior mitral leaflet [SAM] which induced mild mitral regurgitation [Seller Grade I/IV] and pressure gradient about 60 mmHg between left ventricle and the aorta. Medical treatment with 8-adrenergic blockade [propranolol] and Ca" channel antagonist [Verapamil] had no response. So, we performed trans-aortic ventricular septal myotomy and mymectomy. Resected rectangular muscle bar was 1 Cm x 1 Cm x 4.5 Cm. Post-operative pressure gradient between the left ventricle and the aorta was less than 10 mmHg and SAM. was disappeared with decreased mitral regurgitation grade. Post-operative course was smooth and his symptoms and signs were free without any medication during 12 months follow-up.w-up.

Over the past 6 years, from July, 1981. through June, 1987., 14 consecutive patient with congenital aortic stenosis underwent corrective surgery in our department of Thoracic and Cardiovascular Surgery. The patient ranged in age from 1 to 20 years. There were 8 male and 6 female patients. According to the operative findings, stenotic site was valvular stenosis [5 cases], subvalvular stenosis [5 cases], supravalvular stenosis [2 cases], valvular and supra valvular stenosis [1 case]. We have performed valvotomy and commissurotomy [5 cases]. Resection of subvalvular membrane [3 cases], patch enlargement of Ascending aorta [2 cases], LV myotomy [2 cases], valvotomy and excision of membrane [1 case], patch enlargement of ascending aorta and valve ring [1 case]. There was one hospital mortality [7.1%]. He died of C-I bleeding and sepsis on the 25th postoperative day. All survivors showed improvement in NYHA functional class in the 160 patient/month follow up period.

Eophagocardiomyotomy (modi/red Heller procedure) is a widely accepted operation for relief of dysphagia in patients with esophageal achalasia. But patients with advanced achalasia were more likely to get poorer results from a modified Ileller myotomy hecause of the dependent pouch that creates an angulation at the junction of thick-walled dilated esophagus with the thin walled aganglionic segment and hinders complete emptlllg. Thorhjarnarson(1975) prposcd the method including truncal vagectomy and pyloroplasty. Vagectomy and pyloroplasty should lesson the severity of acid-peptic esophagitis, if reflux should occur postoperatively. Here we presented 4 cases esophageal achalasia treated by modified Heller operation of 3 cases and one case of Thorbjarnarson method. All postoperative results are good.

A pharyngeal diverticulum is a rare complication of an anterior cervical discectomy and fusion (ACDF). We present a case of a pharyngeal diverticulum after an ACDF, which was misdiagnosed as a typical Zenker diverticulum. A 54-year-old woman presented with dysphagia and a sense of irritation in the neck following C5 through C7 cervical fusion 3 years prior. The patient underwent open surgery to resect the diverticulum with concurrent cricopharyngeal myotomy. An ACDF-related diverticulum is difficult to distinguish from a typical Zenker diverticulum.

In the case of the trauma on the maxillofacial region occurred, we think that one of the most important thing is recovery of the function as well as reconstruction of the anatomical form. Especially, it has been that the structure of the surrounded temporomandibular joint has a great possibility to cause mouth opening limitation when a bit of displacement is caused. Therefore, in the case of the trauma on mid-face we think that we treat it after complete evaluate condition of soft and hard tissue surrounding the articular disc as well as fracture site. We report results of our study, since we obtained good results from our study concerning the refixation of the zygomatic arch, high condylectomy, coronoidectomy and myotomy for the patient being suffered from the arthrosis of the temporomandibular joint caused by insufficient fracture treatment of zygomatic arch and coronoid process.

Six cases of achalasia were treated by modified Hellers operation at the department of thoracic % cardiovascular surgery of Kosin medical college from April 1984 to July 1988. Among 6 cases, 4 were male and 2 were female. Preoperative main symptoms were dysphagia in 5 cases and regurgitation in 1 case, its duration was variable from 1.5 years to 40 years. Esophagocardiomyotomy was perfomed in all cases, and the results were excellent to good, but reoperation was needed in one case due to incomplete myotomy. One case of advanced achalasia was also experienced and the result was satisfactory. Antireflux procedures were not performed in all cases and there was no reflux esophagitis on follow-up study.
