There are many vital structures in the neck, but they are not protected by bone. The neck is vulnerable to injury, and difficult to evaluate the extent of injury. Especially, penetrating neck wounds are potentially dangerous and require emergency treatment. A 56-year-old man with a penetrating neck injury by a grass cutter fragment was transferred from another hospital. There were no immediate life-threatening signs or symptoms. Carotid artery injury was suspected in the computed tomography scan. Emergent exploration was implemented by vascular surgery to remove the grass cutter fragment that had penetrated the left common carotid artery. We report a rare case of common carotid artery penetrating injury that was treated without any complications.

조기 선천성 진주종에서 최소 침습적 경외이도 고막절개술의 임상적 효용성
강기근,서지원,정성욱,홍종철,강명구 대한이비인후과학회 2014 대한이비인후과학회지 두경부외과학 Vol.57 No.7
Background and Objectives Because of the wide application of the endoscopic diagnostic system and increased amount of attention for early stage congenital cholesteatoma (CC) recently, the detection of CC in stages I and II has increased. In this study, we investigated the effectiveness of minimally invasive transcanal myringotomy (MITM), and compared its results with those of postauricular approach (PAA) in early stage CC consisting of stage I and II of Potsic’s classification. Subjects and Method We retrospectively studied 70 patients who were diagnosed with CC after surgery performed by an otologist from June 2006 to June 2013. Thirty-two patients were in early stage CC consisting stage I and II. Of the 32 patients, MITM was performed on 20 and PAA was performed on 12. We analyzed the characteristics of disease, operation time, hospitalization period, recurrence and complications according to the stage and each operation. Results There were no significant differences between the stages and types of the disease between the MITM and the PAA group (p>0.05). The operation time and hospitalization period for the MITM group were significantly shorter than for the PAA group (p<0.001). There was no recurrence in the two groups during the average follow-up period of 33 months follow-up. Tympanic membrane perforation occurred in one patient in the MITM group. One patient presenting an external aural epidermal cyst in the PAA group was treated with surgical removal. Conclusion The MITM is an efficacious and feasible method to remove early stage CC.

Neurofibroma arising solitarily in the larynx is uncommon. With the branch of the superior laryngeal nerve involved, the aryepiglottic fold is the most common site in endolaryngeal neurofibromas. The recurrence rate for the disease is high unless en bloc excision, the treatment of choice, is taken. We present a case of neurofibroma in a 58-year-old female who complained of throat discomfort and dysphagia. The mass was removed by transoral laser surgery and no recurrence was found after 18 months.

Objectives:Ethanol injection under ultrasound guidance has been proposed as an alternative to surgery in the treatment of benign thyroid cysts. So we evaluated efficacy and safety of ultrasonography guided ethanol sclerotherapy for cystic thyroid nodules with analyzing results retrospectively. Methods:Between May 2010 and Jun 2012, 18 cystic thyroid nodule patients (19 cysts) were treated with ethanol ablation. We evaluated the treatment outcomes with the change of volume reduction and the improvement of symptomatic and cosmetic complains and complications. Results:Initial mean cystic nodule volume was 8.5 mL (range, 0.4-31 mL) and mean volume after ablation 1 week was 5.7 mL (range, 0.02-21 mL) in ultrasonography (p=0.154). Each of the mean volume at 1 month and 6 months after treatment was 2.9 mL (0-13 mL, p=0.002) and 0.8 mL (0-5.9 mL, p=0.000). The mean volume reduction rate was 90% (50-100%). Mean symptoms and cosmetic grading scores improved from 5 to 1.7 and from 3.5 to 1.5 (p=0.000). No significant complications were observed during the follow up. Conclusions:Percutaneous ethanol injection may prove a safe and effective tool for the therapy of the benign thyroid cysts.

Teratoma is a tumor derived from totipotential cells and composed of tissues originating from all 3 germinal layers. The tumor can be malignant based on histologic differentiation, size and location and is commonly found in the sacrococcygeal region, but uncommonly occurs in the head and neck region. A mature teratoma rarely occurs in the Eustachian tube. The authors of the current study present a case of a mature teratoma originating from the Eustachian tube of a 23-year-old woman who complained of left otorrhea. In addition, a review of the literature is presented.

Osteoma is a slow-growing benign tumor that consists of mature or cancellous bone. It most commonly occurs in the frontoethmoidal area of the paranasal sinus and is usually asymptomatic. Surgical excision is necessary for osteoma, which causes symptoms such as headache, nasal obstruction, facial asymmetry, and visual disturbance. Surgical approaches should also be considered depending on the size and location of the osteoma, in order to reduceintracranial and orbital complications. We recently treated a huge frontoethmoid osteoma involving the skull base and orbit, which was removed via endoscopic sinus surgery and a combined extracranial approach. Herein, we report this case with a review of the relevant literature.

경구강 레이저 절제술로 치유한 성문상부 선양낭성암종 1예
박헌수,홍종철,이동근,강기근 대한이비인후과학회 2012 대한이비인후과학회지 두경부외과학 Vol.55 No.4
Adenoic cystic carcinoma (ACC) is a malignant tumor, occuring in the major and minor salivary glands. Laryngeal ACC is a rare malignancy that constitutes less than 1% of all laryngeal malignancies. ACC is characterized by slow growth, multiple recurrences and late distant metastasis. The treatment of the ACC is by wide excision or by combining wide excision with postoperative radiotherapy. A 33-year-old woman, who had been diagnosed with epiglottic cyst in 2007, complained of throat discomfort that had been aggravating for the past two weeks. The tumor was treated with transoral laser excision. The pathologic report revealed an adnoid cystic carcinoma on the epiglottis; it was composed of cribriform patterned nests and columns of tumor cells. No recurrence was detected until post-operative 16 months by endoscopic examination. Transoral laser excision was suggested for successful treatment for the adenoid cystic carcinoma.
