The Neurofibroma is a benign neoplasm originating from neural tissue such as Schwann cell, fibroblast and peripheral fibroblast, which rarely converts to malignancy. About 25-45% of neurofibroma are located in head and neck, and the most common sites are lateral cervical region and mouth. Because of its high vascularity and invasion to the adjacent organs, surgical resection may be confronted and limited, moreover large neurofibroma can cause large defect that needs various kinds of flap. The factors related to clinically suspected malignancy are painlessness, abrupt increase in size, firm fixation, and central ulceration, although the malignancy rate of neurofibroma is low. The complete resection was failed several times at local clinic, the patient was transferred to our hospital. We have successfully removed the retroauricular neurofibroma using transposition flap & free skin graft on its large defects.

An advanced maxillary sinus cancer requires an extensive ablation that results an extensive facial deformity, including a skin defect. Reconstruction has to be considered in a radical maxillectomy, especially with skin defect may be accomplished in one stage with a microsurgical free transfer of a latissimus dorsi flap. A man of right maxillary sinus cancer, squamous cell carcinoma, 47 years old of age, had soft tissue invasion of the cheek region. He underwent a radical maxillectomy with extensive skin excision. The maxillectomy and skin defects were reconstructed with the double skin island latissimus dorsi myocutaneous free flap. The cosmetic result and the functional outcome of the nose were thought to be considerably satisfied.

Synovial sarcomas of the hand are rare. It should be treated with wide resection. In the cases of soft tissue sarcomas of the hand, functional reconstruction must be considered. We report 46-year-old male patient with synovial sarcoma of the right thenar muscle which was treated with unplanned intralesional resection at outside hospital, that has been treated with wide resection including trapezium and first metacarapl bone then, reconstructed with nonvascularized fibular graft and anterolateral thigh free flap.

A radical maxillectomy causes a defect of the alveolar bone, gingiva, palate, and orbital floor and causes cosmetical problems and masticatory and phonatory functions. Defect after a radical maxillectomy was reconstructed with skin or dermis graft was introduced, but recently wide resection of the tumor and functional reconstruction with free flap was introduced by several methods. The defect due to radical maxillectomy was reconstructed with scapula, iliac crest, radius. But reconstruction with a fibular osteocutaneous free flap was rarely introduced to defect of radical maxillectomy. The fibular osteocutaneous free flap was firstly introduced by Taylor. The fibular osteocutaneous free flap has several advantages. We experienced the first case of radical maxillectomy and reconstruction with the fibular osteocutaneous free flap, so we reported that case with literatures. The patient has a right maxillary sinus squamous carcinoma (T2N0M0), and performed a radical maxillectomy with right supraomohyoid neck dissection, and reconstruction with fibular osteocutaneous free flap. Donor site morbidity was little, and phonatory and masticatory function were nearly normalized. And cosmetical result was very acceptable.

Chyle fistula is one of the complications of neck dissections. Although immediate surgical repair seems to be the best choice when chyle leakage is observed during the operation, some operators can be embarrassed when chyle leakage is heavy and not controlled during surgery. In this case, chyle leakage was occurred after extensive resection of lymph nodes in left level IV, and was not controlled in any way. The clavicular head of sternocleidomastoid muscle was dissected and inferior-based muscular flap was rotated to cover the suspected region of fistula orifice. Amount of drainage was checked less than 20 ml per day in the following days, and drain tube was taken out on the 3rd postoperative days. We present the technique using the inferior based sternocleidomastoid muscle flap for intraoperative management of chyle leakage not easily controlled.
