Traditionally, the main strategy of treatment of the head and neck cancer was en bloc resection including adjacent normal tissues through wide incision. However, the procedures may leave severe functional deficit such as swallowing difficulty, aspiration, and wide neck scar. Therefore, many attempts have been made up to minimize these morbidities. Of them, the minimal invasive approach such as transoral laser microsurgery (TLM) and transoral robot surgery (TORS) have been spolighted as a sensible strategy for organ preservation of the head and neck cancer patients. Results of TLM are equivalent to those obtained by conventional surgery, with considerably less morbidity, less hospital time and better postoperative function. Oncologic results of TLM are equivalent to conventional surgery. TORS are safe, feasible, and promising but oncologic safety is not yet verified. This article covers to current application of TLM and TORS, their advantages and limitations, and future direction.

Benign submandibular gland tumor is a common disease in the head and neck region and can be completely removed by transcervical approach. Typical submandibular gland resection can lead to neurological complications. The most common complications are damage to the marginal mandibular branch of the facial nerve and weakening of the lower lip. We report a case of ipsilateral lower lip twitching occurring 3 months after surgery. There was no difficulty during the operation, and there were no neurologic complications immediate after surgery. However, in the present case, the patient experienced lower lip twitching paradoxically after surgery which has not been reported in the literature yet. Therefore, we reported this case with a review of relevant literature.

Chronic invasive aspergillosis is a life-threatening disease, especially in immunocompromised patients. The diagnosis and treatment of tracheal aspergillosis (TA) are challenging because of its rarity and nonspecific clinical presentations. The treatment standard of TA has been medical treatment like other forms of invasive aspergillosis, but patients with medically resistant TA require surgical intervention. We demonstrated a successful surgical outcome of chronic invasive TA in a 16-year-old patient with immunocompromised status related to acute myelocytic leukemia.

Soft tissue sarcoma of the head and neck is not frequent neoplasm, accounting for less than 1% of all malignant neoplasm in the region. The histological varieties include osteogenic sarcoma, malignant fibrous histiocytoma, rhabdomyosarcoma, fibrosarcoma, tenosynovial sarcoma, angiosarcoma and chondrosarcoma. Rhabdomyosarcomas of the head and neck usually occur in children under the age of 10 years (over 70%) and rarely develop in adults over the age of 20 years. The prevalent sites of involvement include the orbit, nasal cavity, external ear, paranasal sinus and soft tissue of mouth and the primary location of tumor is considered to be one of the important prognostic factors. Before the 1960s, when surgical resection was the only method of treatment, the 5-year survival rate was less than 20%, but recently it has been greatly improved by the multimodality treatment, combining surgery with chemotherapy and radiation therapy. Here we treated a rhabdomyosarcoma woman with three cycles of high dose chemotherapy followed by radiation therapy. After the, completion of preoperative treatments, successful result of more than partial response was achieved. Three months later total maxillectomy and radical neck dissection was performed. There was no evidence of tumor infiltration in the resected tumor and regional lymphnodes but metastasized tumor cells in cervical lymphnodes were detected. Tumor cell infiltration was also found on the bone marrow biopsy to evaluate the pancytopenia which occurred during postoperative recovery. Two months later she died of secondary bone marrow failure. We think that this multimodality treatment combining pre-operative chemotherapy, radiotherapy and surgery might play an important role in curative resection and eyeball preservation in patients with rhabdomyosarcoma involving the eyeball.

Salivary duct carcinoma(SDC) is a highly malignant tumor of the salivary gland. The tumor is clinically characterized by a rapid onset and progression, the neoplasm is often associated with pain and facial paralysis. The nodal recurrence rate is high, and distant metastasis is common. SDC resembles high-grade breast ductal carcinoma. Curative surgical resection and postoperative radiation were the mainstay of the treatment. If facial paralysis is present, a radical parotidectomy is mandatory. Regardless of the primary location of SDC, ipsilateral functional neck dissection is indicated, because regional lymphatic spread has to be expected in the majority of patients already at time of diagnosis. If there is minor gland involvement, a bilateral neck dissection should be performed, because lymphatic drainage may occur to the contralateral side. The survival of SDC patient is poor, with most dying within three years. We experienced a unique case of SDC in parotid deep lobe. We report the clinicopathologic features of this tumor with a review of literature.

Mammary analogue secretory carcinoma (MASC) of the salivary gland is a newly classified pathologic entity since 2010. Prior to its recognition, MASC was diagnosed as low-grade cystadenocarcinoma, acinic cell carcinoma, and mucoepidermoid carcinoma. MASC shares common histological and genetic characteristics with secretory carcinoma of the breast and has a distinct feature of the ETV6-NTRK3 fusion gene. Treatment of MASC in salivary gland is mainly wide surgical resection of the tumor. Prognosis of MASC is similar to other low-grade salivary gland carcinomas. Herein, we report a case of MASC developed in a parotid gland with a review of the literature.

Esophageal diverticulum is a rare entity, the true incidence of which is unknown, mainly because there are usually no clinical symptoms. Most esophageal diverticulum are found incidentally during an endoscopic or radiologic examination. Their classification is based on anatomical location; namely, upper third(Zenker or pharyngoesophageal), middle third(thoracic), or lower third(epiphrenic). Here we report a 52-years-old female presenting with dysphagia and regurgitation. Esophagogram showed esophageal diveticulum at lower cervical esophagus. Its positional aspect, it is different from Zenker's diveticulum. Treatment is surgical via an endoscopic or external approach. In view of the patient's age and anatomical location, various surgical approaches were considered as a therapeutic option for the management. This paper presents our experience in the management of esophageal diverticulum which was unusual location and stapled open resection without sternotomy.

Hemangioma is one of the most common benign neoplasm, which occurs about 50% in head and neck region, but laryngeal hemangioma is relatively rare. Hemangioma occurred in larynx can be treated by surgical removal, cryosurgery, and steroid injection. Transoral CO2 laser micorsurgery has been known as useful method for the treatment of laryngeal hemangioma. We have experienced a 54-years old male patient of hemangioma originated in arytenoid area. This mass was removed via transoral approach with 'en bloc' resection by CO2 laser. We report this case regarding the treatment and prognosis of laryngeal hemangioma with review of literatures.

Granular cell tumors are relatively uncommon benign laryngeal lesions thought to originate form Schwann cells. The granular cell tumor occurs everywhere in the body, especially in the head and neck. The larynx is relatively an uncommon location, accounting for approximately 3 to $10\%$ of all reported cases. Typically the most common presenting symptom is hoarseness, with some patients also presenting stridor, hemoptysis, dysphagia, and otlagia. But the tumor may be asymptomatic and discovered only incidentally during a routine examination. The diagnosis of granular cell honor can be confirmed by histopathologically and immunocytochemical staining fer S-100 antigen. Treatment of a granular cell tumor consists of a wide local excision by the endoscopic, transoral or laryngofissure methods. Recently, CO2 laser has been used to remove granular cell tumor with clear resection margin. This article describes one such case in a 62-year-old man, followed by a brief review of the literature on this subject.

Follicular thyroid carcinoma (FTC) is the second most common thyroid cancer, following papillary carcinoma. Metastasis to the orbital rim from FTC is very rare. We recently experienced a case of FTC with metastasis to the orbital rim in a 74-year-old woman, who initially presented with a huge thyroid mass and an asymptomatic solitary orbital rim lesion. The solitary orbital rim lesion was suspected to be a separate disease entity such as lymphoma from the preoperative imaging, but bone metastasis from FTC was finally confirmed after orbital rim resection and total thyroidectomy. During follow-up, the patient presented multiple bone metastasis, so the solitary orbital rim lesion was considered a clinical sign of systemic metastasis from FTC. Therefore, we present this unique case with a review of the literature.
