A 39-year-old man presented with a esophageal submucosal tumor on regular check up examination. Preoperative exams showed the typical submucosal tumor as leiomyoma and operative procedure was enucleation for complete resection. Postoperative pathologic diagnosis including histologic and immunohistochemical study was compatible with plexiform schwannoma. Plexiform schwannoma is one of the least common variant of schwannoma that typically shows a plexiform or multinodular pattern. To our knowledge, there is rare case report of plexiform schwannoma originating in the esophagus and we report ore case with related literature.

Fourth branchial pouch anomaly is an extremely rare condition involving the pharyngeal apparatus with only about 30 cases having been reported in the last 20 years. It almost invariably occurs on the left side and typically presents with repeated episodes of neck swelling, recurrent thyroiditis, or repeated bouts of retropharyngeal abscess. This is a presentation of 2 patient with pyriform sinus fistula, presumably of fourth branchial origin, which, were successfully closed with 10ole trichloroacetic acid chemical cautery. Details of the cases along with the summary of embryology and fourth branchial anomaly are given.

The deformities of the auricle is rare and classified roughly into two categories as "Hyperplasia and Hypoplasia". Microtia occurs about once in every 6000 births and is twice as frequent in males as in females and the unilateral to bilateral ratio is roughly 8 : 1. Significant malformation of the auricle frequently involves the external auditory canal and the contents of the middle ear. Recently, the authors experienced a case of hypoplasia of the superior third of the right auricle of 24 year old male, with neither hearing impairment nor any other associated defect, who was surgically corrected by rotation flaps through post-auricular incision.

Bronchogenic cysts are anomalous cystic lesions of foregut and usually located in the lung or mediastinum. Generally intramuscular cysts of the esophagus are considered as enterogenous foregut malformations. We report a young adult with an intramural bronchogenic cyst causing dysphagia and heartburn. It was located in the muscular layer of the esophagus and was removed without any damage to the mucosa. Histopathologic findings revealed that it was a bronchogenic cyst.

There are over 60 types of hereditary hearing loss in man and most of these are distinguished from one another by outstanding associated defects caused the same gene producing hearing loss. However, there are at least 12 types of hereditary hearing loss with no known associated defects. The authors experienced two similar families with hereditary hearing loss. The affected offsprings had inevitably an affected parent in type of transmissin (autosomal dominant) and the hearing loss developed in childhood and progressed. Audiologic findings showed bilateral symmetrical moderate to severe sensori-neural hearing loss with flattened configuration on the audiogram. Vestibular function tests showed no abnormal findings and the associated anomalies could'nt be observed in history or clinical examinations.

선천성 후두열은 매우 드문 선천성 기형으로 신생아에게 심각한 호흡곤란 및 수유장애를 초래할 수 있다. 해부학적 결손정도와 관련된 기형에 따라 다양한 증상이 나타난다. 가장 흔한 특징적 증상으로는 흡기시 천명, 간헐적으로 나타나는 수유시 호홉곤란을 들 수 있다. 이 증상들은 후두연화증, 성대마비, 후비공폐색 둥과 같은 다른 선천성 기형에서도 나타나기 때문에 미리 의심하지 못하면 진단이 어렵다. 따라서 진단을 위해서는 세심한 주의와 정확한 내시경 검사가 필요하다. 저자들은 선천성 후두열 2례를 경험하였다. 첫 증례는 제 II형이었고 두번째는 III형이었으며, 두 증례 모두 전방 후두열 접근법으로 치료하였다. 제 III형 환아는 술전 흡기시 천명을 동반한 호흡곤란과 여러번의 흡인성 폐렴을 겪었으며 술후 캐놀라발거는 가능하였으나 경구를 통한 수유시 흡인을 동반하여 현재까지 위루술을 통해 음식을 섭취하고 있는 상태이다. 저자들은 최근 경험한 선천성 후두열 2례를 video presentation과 함께 보고하는 바이다.

Interrupted aortic arch with concomitant intracardiac defects is a rare congenital anomaly that has an unfavorable natural course. We report a successful staged operation of interrupted aortic arch with apical muscular ventricular septal defect associating esophageal atresia with tracheoesophageal fistula in a 3-day-old neonate weighing 2.6 kg. We repaired esophageal atresia through the right thoracotomy and subsequently performed extended end-to-end anastomosis of the aortic arch with pulmonary artery banding through the left thoracotomy at same operation. The apical muscular VSD was repaired 87 day after first operation. The patient required multiple additional interventions before closure of the apical muscular ventricular septal defect, such as pyloromyotomy for idiopathic hypertrophic pyloric stenosis, anterior aortopexy for airway obstruction, and balloon aortoplasty for residual coarctation. She is now doing well.
