Objectives : In $CO_2$ laser surgery for supraglottic cancer, neck dissection is generally done in second stage. We investigated simultaneous neck dissection with primary resection could be available in laser supraglottic surgery. Material and Methods : We analyzed 13 patients with supraglottic cancer who were treated with transoral supraglottic laryngectomy and simultaneous neck dissection from 2001 to 2007. Tumor stage, extent of laser surgery, histological results, survival rate, local control rate, complications, and functional results were reviewed. Results : 5-year local control rate, survival rate and disease specific survival rate from the neck was 100%, 69.9%, 100% respectively. Tracheotomy was done in all 13 cases. One patient had a long tracheotomy indwelling (191 days). In the rest of 12 patients average decanulation time was 7.4 days(1-22 days). Nasogastric tube was inserted in 5 cases, and average oral intake was possible in 3.5 days(1-16 days). Average hospital days was 29.7 days. There was no serious complication associated with neck dissection. Conclusion : Simultaneous neck dissection with primary laser resection for supraglottic cancer is oncologic sound and can be performed without significant surgical morbidity.

Purpose: We compared the results of three surgical procedures of the old neglected Freiberg's disease that was managed with metatarsal head reshaping, metatarsal head resection, and dorsal closing wedge osteotomy. Materials and Methods: From march 1996 to July 2002, five cases in six patients whose metatarsal head collapse already progressed underwent operative treatment. We compared the operative results in the view point of the radiographic follow-up and lesser toe metatrasophalangeal joint scale of AOFAS. Results: There were no further joint destruction and loose body formation. Also, lesser toe metatrasophalangeal joint scale of AOFAS improved from average score, 38.5 (range $22{\sim}49$) of preoperative one to average score, 86.6 (range, $72{\sim}100$). Especially, the 2 cases that underwent dorsal closing wedge osteotomy showed most favorable result and the 2 cases with metatarsal resection showed next favorable result. The 2 cases with intra-articular loose body removal and metatarsal reshaping showed the least effective result among three operative methods. Conclusion: Our Operative experiences of old neglected Freiberg's disease were all satisfactory irrespective of operative options and dorsal closing wedge osteotomy was thought to be most effective method.

목적: 주위 장기를 침범한 진행성 위암에서 병소의 완전한 절제를 위해서는 침범된 장기의 합병 절제가 필수적이다. 그러나 종양이 췌장 두부나 십이지장물 침범하는 경우에는 낮은 절제 성공과 높은 이환율로 인하여 병소의 완전한 절제는 제한된다. 이에 저자들은 췌장 두부 또는 십이지장을 침범한 위암에서 시행된 수술 방법을 후향적으로 분석하여 수술 방법 선정의 적절성을 알아보고가 하였다. 대상 및 방법: 1998년 1월부터 2003년 12월까지 5년가 예수병원 외과에서 위선암으로 진단되어 수술을 시행한 환자 중 수술 소견상 원발 종양이나 구역 림프절에 의해 췌장 두부나 십이지장의 침범이 의심되는 45명의 환자 중 비치유 인자를 동반하지 않은 22예를 대상으로 후향적 연구를 시행하였다. 합병 절제를 시행한 4예를 PD군, 위아전절제술만을 시행한 12예를 STG군, 고식적 우회술만을 시행한 6예를 GJ군으로 분류하였다. 각 군에서 임상병리학적 특성 및 수술적 자료를 비교 분석하였다. 결과: PD군은 모두 D3 림프절 절제술을 포함하는 췌십이지장절제술을 시행하여 병소의 완전한 절제를 하였으며, 1예에서 췌장루를 보였고(이환율 25%) 수술로 인할 사망 예는 없었다(사망률 0%), PD군은 모두 제 IV 병기였으나 75%의 2년 생존율과 50%의 5년 생존율을 보였다. STG군은 종양을 변연 절제(marginal resection)하거나 (6예) 고식적 절제술을 시행하였으며(6예) 림프절 절제의 범위도 D2 이하로 적었고 41.7%의 2년 생존율과 16,7%의 5년 생존율 보였다. GJ군은 평균 연령이 $72.7{\pm}8.6$세로 고랑이었으며 2년 생존율이 0%였다. 결론: 췌장 두부를 침범한 진행성 위선암에서 합병 절제로서의 췌십이지장절제는 중등도 이환율과 낮은 사망률로 비교적 안전하게 시행될 수 있고 비치유 인자가 없는 경우 장기 생존을 기대할 수 있는 술식으로 생각된다.

The surgical treatment of advanced carcinomas and some benign tumors having clinically malignant behaviors of the head and neck region often require extensive resection, necessitating large flaps for reconstruction. Since the original upper arm flap was described by Tagliacozzi in 1597, a variety of technique such as random pattern local flap, axial flap, distant flap, scalping flap, myocutaneous flap, free flap etc. have been proposed for reconstruction of head, face and neck defects. Reconstruction of the facial defects usually require the use of distant tissue. Traditionally, nasal reconstruction has been carried out with a variety of forehead flaps. In recent years, there has been more acceptance of immediate repairs following the removal of these tumors. As a result, patients are more willing to undergo these extensive resections to improve their chances of cure, with the reasonable expectation that an immediate reconstruction will provide an adequate cosmetic result. Authors experienced 13 cases of head and neck tumor during last three and half years that required wide excision and immediate reconstruction with various flaps, not with primary closure or simple skin graft. We present our experience with varied flaps for reconstruction after wide resection of head and neck tumors 3 cases of defect of dorsum of nose or medial canthus with island forehead flaps, lower eyelid defect with cheek flap, cheek defect with Limberg flap, orbital floor defect with Temporalis muscle flap, lateral neck defects with Pectoralis major myocutaneous flap or Latissimus dorsi myocutaneous free flap, subtotal nose defect with scalping flap, wide forehead defect with Dorsalis pedis free flap and 3 cases of mandibular defect or mandibular defect combined with lower lip defect were reconstructed with free vascularized iliac bone graft or free vascularized iliac bone graft concomitantly combined with free groin flap pedicled on deep circumflex iliac vessels We obtained satisfactory results coincided wi th goal of treatment of head and neck tumors, MAXIMAL CURE RATE with MINIMAL MORBIDITY, OPTIMAL FUNCTION, and an APPEARANCE as close to normal as possible.

Carotid body tumor is a rare benign tumor arising from the paraganglionic tissue of neural crest. Surgical management remains the prefered treatment. Large carotid body tumors frequently encircle the internal carotid and external carotid arteries, and extensive bleeding often complicates the resection, increasing the risk of carotid artery rupture and damage to major cranial nerves. Recent improvements in surgical techniques and selective embolization have lessened the risks of surgical excision, decreased blood loss, and diminished the time required for resection. The review of literatures revealed a few cases of the carotid body tumor with papillary carcinoma of the thyroid. We report a case of the huge carotid body tumor with papillary carcinoma of the thyroid, which was removed by 4 times of preoperative embolization and transcervical approach.

Purpose : To evaluate the effect of radial head resection on longevity in nonconstrained total elbow arthroplasty, Materials and Methods : The results of 20 cases of radial head replaced Pritchard ERS and 18 cases of radial head excised Kudo elbow was followed for 6 to 16 years, 10.6 years in average. The rate of loosening, osteolysis, radial head subluxation, joint dislocation and valgus deformity were compared between the two groups. Results'There was no exaggerated cubitus valgus in Pritchard ERS group. However there developed one case of delayed subluxation of radial head occurred in 6 years postoperatively, one case of loosening, and one case of sponta- neous fracture of humeral shaft due to osteolysis. In Kudo elbow group,5 cases (27.8%) showed exaggerated valgus deformity with instability. There were one case of loosening and one case of delayed dislocation occurred in a year postoperatively. Conclusion : The most clear feature of Kudo elbow was exaggerated cubitus valgus. However, the ostolysis was developed in both groups and there was no difference in rate of the other complications between the two groups.

Background: Treatment for venous malformations of the head and neck includes sclerotherapy, surgical resection, or a combination of both. Surgical resection can remove or reduce the volume of vascular lesions; however, surgery can cause postoperative scarring and potential surgical complications. This study sought to determine the effectiveness of surgery for the treatment of venous malformations of the head and neck. Methods: A retrospective review of the medical records of patients who received surgeries for venous malformations of the head and neck from January 2011 to July 2019 was performed. Using clinical photographs, preoperative and postoperative Doppler ultrasonography, outpatient clinic records, and operation records, the postoperative result and complications were evaluated for each case. Results: Among patients who visited our vascular anomalies clinic, 43 patients (ratio of male to female= 24:19) received surgeries for venous malformations of the head and neck. Twenty-nine patients had undergone surgery only, five patients received sclerotherapy after surgery, and nine patients received surgery after preoperative sclerotherapy. In postoperative evaluations, the result was excellent in 24 patients, good in 18 patients, and poor in one patient. Four patients experienced a recurrence of lesions with lagophthalmos, drooping of the corner of the mouth, partial wound necrosis, and scar widening found in one patient each. Conclusion: Because the head and neck region is the most exposed area in the body, more active implementation of surgical treatments with or without sclerotherapy is essential to reduce the functional and cosmetic impairments associated with venous malformations.

Computer-aided surgery (CAS) started being used for head and neck reconstruction in the late 2000s. Its use represented a paradigm shift, changing the concept of head and neck reconstruction as well as mandible reconstruction. Reconstruction using CAS proceeds through 4 phases: planning, modeling, surgery, and evaluation. Thus, it can overcome a number of trial-and-error issues which may occur in the operative field and reduce surgical time. However, if it is used for oncologic surgery, it is difficult to evaluate tumor margins during tumor surgery, thereby restricting pre-surgical planning. Therefore, it is dangerous to predetermine the resection margins during the presurgical phase and the variability of the resection margins must be taken into consideration. However, it allows for the preparation of a prebending plate and planning of an osteotomy site before an operation, which are of great help. If the current problems are resolved, its applications can be greatly extended.

The soft palate of carcinoma limited to the uvular region is infrequent among oropharyngeal cancers. The oropharynx regulates swallowing and speech through dynamic motions. Failure to reconstruct after surgical resection of the oropharynx structure can lead to permanent velopharyngeal insufficiency. Therefore, suitable reconstruction is important in establishing proper functional outcomes while maintaining oncological safety. We present a case of a 66-year-old male who was diagnosed with oropharynx cancer limited in the uvula accompanied by lymph node metastasis. After surgical resection, reconstruction was performed with the united arrangement of bilateral palatal mucomuscular flap and superiorly based posterior pharyngeal flap. There was no aspiration or reflux after feeding and epithelialization completely occurred after 1 month postoperatively. We report a successful case that the reconstruction with the local flap described above could preserve proper oropharyngeal function after primary surgery in small-sized oropharyngeal cancer.
