Epidermal cysts are generally benign tumors that usually originate from the skin caused by inflammation of hair cortex and proliferation of epidermal cells within the dermis; however, for these cysts to occur in the bony external auditory canal (EAC) is rare. They are often present as a solitary, painless lesion and usually asymptomatic and the diagnosis depends on the results of the histological examination. In treatment, the cyst wall must be completely removed surgically. We recently encountered a 82-year-old male with a mass in the right EAC. An otoscopic examination showed a polypoid mass on the bony EAC, which was finally diagnosed as epidermal cyst after an initial misdiagnosis as EAC carcinoma. We report the rare, unique case with literature review.

Malignant melanoma can be classified as both cutaneous and mucosal types. The former comprises more than 98% of all melanomas and is related to ultraviolet exposure, whereas the latter occupies only 1.3%. More than half of mucosal melanoma arises in the head and neck region, and the sinonasal tract is also one of its predilection sites. On the other hand, the metastatic melanoma of head and neck is lower incidence than primary lesion and the unknown primary site is about two to five percent. Moreover, a lymphatic metastasis to the posterior neck is a more unusual clinical pattern. A 71-year-old man with a solitary subcutaneous posterior neck mass visited our clinic. He was confirmed with metastatic melanoma in the lymph node through excisional biopsy. However, the primary site was not found with whole radiologic examinations. We report a very rare disease entity with a brief literature review.

Schwannomas are slow-growing, benign neurogenic tumors arising from the sheath of myelinated nerve fibers. They usually occur in the head and neck region. Only 4% of schwannomas found in the head and neck region originate in the sinonasal tract. Schwannoma of the nasal septum is rarer, and only few cases have been previously reported in the literature. We experienced a rare case of the schwannoma of the posterior nasal septum in a 71-year-old woman. She was treated successfully by transnasal endoscopic surgery. No recurrence was detected within 18 months follow-up period.

Warthin's tumor (WT) is second most common neoplasm in the parotid gland and it can be accompanied by inflammation and necrosis. The chest wall inflammation may present a rapid and fatal clinical course and secondary to parotid abscess is extremely rare. An 81-year-old man came to emergency room complained of rapidly enlarged left parotid mass and inflammatory symptoms and signs around the upper lateral neck. We performed incision and drainage with adequate infection control. He was pathologically diagnosed as abscess. We report the unique and instructive clinical case with a literature review.

The tracheostomy directs external air into the airway tract. This process causes mucosal dryness, irritation and inflammation in the tracheo-bronchial tree. In order to prevent such problems, several methods are applied; ointment application, humidification and careful suction etc. The heat-moisture exchanger (HME) is commercially sold device that assists heating and humidification of the inhaled air. The authors experienced successful treatment outcome of intractable tracheitis caused by repetitive and vigorous intra-tracheal suction by applying HME in a total laryngectomized patient. We report an interesting and didactic case with a brief literature review.

The etiology of laryngeal hemangioma is unclear, and it is classified into infant and adult types. The former is capillary hemangioma and relatively common, the latter is cavernous type and very rare. The adult laryngeal hemangioma mainly occurs in supraglottis and glottis. A 75-year-old man came to our clinic with a voice change that started four months ago. The laryngoscopic finding showed that the surface of oval-shaped mass is covered with turbid exudates. We performed the laryngeal microsurgery with CO2 laser. The mass was pathologically proven as cavernous hemangioma. We report a very rare and didactic case with review of relevant literature.

This study analyzed the factors causing the angular deformity as the tibia fracture below isthmus were treated with interlocking nails. For this purpose, we observed 70 cases of tibia fractures in the Gil General Hospital as subjects. Of the 70 cases under the treatment, 32(45.7%) showed the angulation of over one degree, and 11(15.7%) showed that of 5-10 degrees in any plane. According to the outcomes of this studies, the degree of angulation seemed to have close relation to the length of fracture line. Also, if the fracture line reached to the isthmus, angulation was apt to be caused. Even though most angulated cases had concomitant fibular fracture, fibular fracture, itself, seemed to have no direct relation to angulation. In consequence, the intramedullary interlocking nailing needs special carefulness in the case of breakage of cortical buttress such as long fracture line, butterfly fragment and fracture including isthmus.

We studied 30 patients who participated in accelerated rehabilitation program after ACL reconstruction to evaluate the effects on knee joint function prospectively. This program emphasizes early full hyperextension, early weight bearing as tolerated, and closed-chain quadriceps functional activities with rapid return to sports. Timing of the return to occupation, activity level, manual knee test, range of motion, thigh circumference, Lysholm knee score and KT-2000 arthrometer measurement were checked at the latest follow-up which is at least more than 1 year. The result were as follows: 1. The mean time for patients to return to occupation was 7.5 weeks (2 weeks-6 months). 2. Range of motion of the knee were not limited in 25 cases (83%) at 1 year after reconstruction. 3. The mean Lysholm score was 92.7. 4. The mean manual maximum KT-2000 arthrometer score was 2.0mm. The results of this study show that patients who had an ACL reconstruction with an autogenous central 1/3 patellar tendon graft and followed an accelerated rehabilitation program obtained longterm stability, achieved full range of motion, had a low complication rate, and were able to return to full sporting activities predictably.
