Purpose: Electrical burn of scalp is uncommon. Much more, chronically exposed dura in unstable burn scar is quite exceptional. Hence, we report a case of chronically exposed dura following electrical burn. Methods: A 63-year-old man presented with an about 40 years history of an ulcerative lesion arising from electrical burn scar with 'squeeze like sensation' around wound. Wound was about $6{\times}8$ cm. Area in the center was $3{\times}3$ cm nonviable dura without sequestrum. Tangential excision with an intraoperative neurosurgical consultation and transposition flap under general anesthesia was done. Intraoperative biopsy was done. The wound was diagnosed as chronic osteomyelitis, not Marjolin ulcer. Flap was taken successfully. But after 5 days, infectious discharge had been appeared during 2 weeks, despite irrigation and drainage. As flap was re-evaluated, we could see remnant necrotic dura. After that, latissimus dorsi muscle free flap with meshed split thickness skin graft was transferred without excision of necrotic dura. Results: Flap was taken successfully. Follow-up at 10 weeks has been uneventful, with good and stable coverage of the wound. Conclusion: It is true that complete excision of devitalized tissue with sagittal sinus obliteration is prerequisite to flap taken. But necrotic dura was tangentially excised instead of total dura excision, because, posterior two-thirds of the sagittal sinus was involved underneath. Muscle is rich in blood vessels and decrease the recipient-site bacterial count effectively. In this case, muscle flap with skin graft without total dura excision is an alternative treatment.

Laryngopharyngeal reflux (LPR) is the retrograde movement of gastric contents into the larynx, pharynx, and upper aero-digestive tract. LPR differs from gastroesophageal reflux in that it is often not associated with heartburn and regurgitation symptoms. Otolaryngological manifestations of acid reflux include a wide range of pharyngeal and laryngeal symptoms. Belafsky et al. developed a useful self-administered tool, the reflux symptom index (RSI), for assessing the degree of LPR symptoms. Patients are asked to use a 0 to 5 point scale to grade the following symptoms: 1) hoarseness or voice problems; 2) throat clearing; 3) excess throat mucus or postnasal drip ; 4) difficulty swallowing; 5) coughing after eating or lying down; 6) breathing difficulties ; 7) troublesome or annoying cough; 8) sensation of something sticking or a lump in the throat; 9) heartburn, chest pain, indigestion or stomach acid coming up. A RSI score greater than 13 is considered abnormal. As there is no validated instrument to document the physical findings and severity of LPR, Belafsky et al. developed an eight-item clinical severity scale for judging laryngoscopic finding, the reflux finding score (RFS). They rated eight LPR-associated findings on a scale from 0 to 4 : subglottic edema, ventricular obliteration, erythema/hyperemia, vocal-fold edema, diffuse laryngeal edema, posterior commissure hypertrophy, granuloma/granulation tissue, and thick endolaryngeal mucus. A RFS score of greater than 7 was found to suggest LPR-associated laryngitis. Although both indices (RSI and RFS) are widely used, there is some controversy about their validity (sensitivity and specificity) and reliability (intra-rater and inter-rater) in LPR diagnosis and treatment. We discuss the validity and reliability of RSI and RFS with literature review.

Objective : Surgical results for anterior choroidal artery (AChA) aneurysms have previously been reported as unsatisfactory due to inadvertent occlusion of the AChA, while the low incidence of AChA aneurysms hampers the accumulation of surgical experience. The authors reviewed their related surgical experience to document the ischemic complications and surgical outcomes. Methods : Identification of the AChA at its origin by rigorous visual scrutiny, careful microdissection, and meticulous clip placement to avoid the AChA origin are all crucial surgical maneuvers. A retrospective review of a surgical series of 62 consecutive cases of an AChA aneurysm between 2004 and 2012 was performed. Results : All patients, except for five (8.1%) with a small residual neck, showed complete aneurysm obliteration in postoperative angiographic evaluations. There was no incidence of procedure-related permanent AChA syndrome or oculomotor nerve palsy, while three (4.8%) patients suffered from transient AChA syndrome. The clinical outcomes [the 3-month modified Rankin Scale (mRS)] of the patients were related to their preoperative World Federation of Neurologic Surgeons (WFNS) grade. As regards the 3-month mRS, significant differences were found between patients with an unruptured aneurysm (WFNS grade 0; n=20), good-grade subarachnoid hemorrhage (WFNS grade 1-3; n=30), and poor-grade subarachnoid hemorrhage (WFNS grade 4-5; n=4). Conclusion : In surgical treatment of AChA aneurysms, a risk of AChA insufficiency can be minimized by taking every precaution to preserve the AChA patency and intraoperative monitoring. In addition, the surgical outcome is primarily determined by the preoperative clinical state.

Purpose: To correct the facial asymmetry and to achieve symmetry and balance, not only the soft tissue restoration of deficits but also creation and facial contour line such as mandible border and angle is important. Micro fat graft has limitation such as high resorption rate and somewhat limited ability to emphasize the rigid bony characteristics of the mandible angle due to its innate soft consistency. We have investigated the advantages of dermal fat graft over micro fat graft to correct asymmetry of the lower face in patients who had undergone mandibular reconstruction or distraction, using comparative analysis. Methods: Total of 12 patients were enrolled in our study: 6 micro fat graft and 6 dermal fat graft. Postoperative results were compared and analyzed at immediate postoperative period and more than 1 year later in each group with photographs, and analysised with image J program. Result: No complications were noted both in the micro fat type and the dermal fat type of procedures such as fat necrosis or micro calcifications. All of the patients who received micro fat graft, however had considerable amount of fat resorption after the procedure which led to two additional fat graft procedures. Although minor contour obliteration due to contracture was seen in patients who had undergone dermal fat graft procedure, no definite resorption was found even after more than one year follow-up. Results of dermal fat graft patients were satisfactory in terms of mandible angle symmetry. Secondary revision was necessary in one case due to overcorrection using dermal fat graft. Conclusion: The dermal fat graft has many advantages over the conventionally more popular micro fat graft to correct asymmetry of the lower face following mandible reconstruction owing to its lower resoption rate, more effective in emphasizing the natural curvilinear anatomical contours of the mandible angle and body and lower complication rates such as fat necrosis or micro calcifications.

The spontaneous pneumothorax occurs subsequent to a disruption in the continuity of the visceral pleura with escape of free air into the pleural space included primary & secondary pneumothorax that is unrelated to identifiable etiologies such as trauma. In. the 33 year period 1960 to 1993, the 230 cases of open thoracotomy were carried out for definitive treatment of spontaneous pneumothorax, at the Dept. of Thoracic & Cardiovascular Surgery, National Medical Center, Seoul, Korea. There were 193 men & 37 women. They ranged in age from 15 years old to 72 years old. The lesion site was on the right side in 117 and on the left in 97, the 16 cases were in bilateral lesions.Surgical indications included recurrence in 98 cases, persistent air leak in 68 cases, nonexpansion of the lung 37 cases, roentgenologically apparent bullae & blebs in 23 cases, bilateral lesions in 16 cases,combined hemothorax & prevent for recurrence in each 2 cases. The types of operation were bullectomy in 207 cases, wedge resection in 13 cases, decortication & B.P.F. closure in 6 cases,lobectomy in 2 cases, pneumonectomy, plication in each I case. The post operative complication developed in 18 cases[7.8 %], there was I case of death due to sepsis. We believed that open thoracotomy with resection or obliteration of blebs & pleurodes is provided the best protection against recurrence.

Aortic arch syndrome is an unusual disease entity characterized by the narrowing or obliteration of major branches of the arch of the aorta regardless of etiology. We have experienced 2 cases. One of them was 22 years old office girl with 3 months history of headache, intermittent syncope and weakness and claudication on left arm especially during her physical exercise. On physical examination, pulseless on left antecubital and radial artery and blood pressure on left arm was inable to check and coldness with weakness were noted on the same side. Aortic angiography reealed 34% narrowing of left subclavian artery as that of right. But both common carotid artery and both axillary arterial patency were relatively good. Through right supraclavicular and left axillary incision, bypass graft with Gore-tex prosthesis (I.D. 6mm, Length 25 cm) was implanted from right subclavian artery on 2cm distal to origin of right common carotid arery to left axillary artery distal to axillary fossa. End to side anastomosis with preservation of left subclavian artery was done. Postoperative state was stable with blood pressure of 110/70 mmHg on left arm and palpable antecubital and radial pulsation. Another one was 41 year old male patient with 8 months history of pain and numbness on right upper arm and shoulder. On admission, right arm blood pressure was 110/80 mmHg, left arm was 160/110 mmHg, but other physical findings had no abnormalities. Angiography revealed segmental narrowing of right axillary artery on the beginning with 2 cm in length. Operative treatment with right wupraclavicular and right axillary incision, bypass graft with great saphenous vein (Length; 15 cm) from right subclavian artery between scalenus anticus and medius to axillary artery at distal end of axillary fossa was done. The authors report two cases of Aortic arch syndrome treated with bypass graft using Autograft or Gore-tex with good result.

폐엽 절제술후 발생한 지속적인 공기 누출 환자에 있어서 현재 화학적 늑막유착술이 보편적으로 시행되고 있으며, 여기에 쓰이는 늑막유착제로는 talc, tetracyclin, doxycyclin, bleomycin, vibramycin, OK432 등이 있다. 그러나 재팽창이 불완전하여 사강이 남아있는 경우 화학적 늑막유착술 만으로는 그 효과를 기대하기 어려우며, 장기간 흉관을 가지고 있어야 함으로 농흉의 위험성도 증가한다. 따라서 폐절제술 혹은 늑막박피술후 발생한 지속적인 공기누출은 많은 흉부외과 의사의 고민이었다. 자가혈을 이용한 늑막유착술은 이러한 지속적 공기누출에 대한 해결법의 하나로 개발되었으며, 그 기전은 혈괴가 직접 기관지 늑막루를 폐쇄하면서 동시에 사강을 감소시킴으로서 늑막유착을 유발하는 것으로 생각된다. 본원에서는 폐수술후 지속적인 공기누출 2례에서 자가혈과 OK432 그리고 자가혈과 vibramycin을 각각 사용하여 좋은 결과를 얻었다.

치근 파절시, 치수괴사는 주로 치관부 파절편에서만 일어나며 근단측은 생활력을 유지한다. 치근단 파절편의 근관치료는 파절편간 사이 공간의 과잉충전의 높은 가능성 및 잔여 괴사조직 제거의 어려움으로 예후가 좋지 않다. 본 증례에서는 통상적인 치료와는 다르게 치근단 파절편의 근관치료가 이루어졌다. 하지만 재근관 치료시 치근파절 부위에서 저항성과 치근단 파절편 근관으로 접근의 어려움이 있었다. 따라서 추가적인 치료 없이, 치관부 파절편만의 수산화칼슘의 교체 및 정기적인 관찰이 시행되었으며, 최종적으로 근관 충전을 시행하였다. 정기적인 관찰결과 치근단 파절편에서 방사선학적 합병증은 관찰되지 않았으며, 일부 증례에서는 장기적으로 치근단 파절편의 수산화칼슘의 흡수 및 근관 협착 등의 양호한 치유 형태를 보였기에 보고하고자 한다.
