Background and Objectives : The objective of this study was to investigate clinical factors associated with recurrence of nasopharyngeal carcinoma(NPC). Materials and Methods : We performed a retrospective review of 112 diagnosed as nasopharyngeal carcinoma, treated concurrent chemo-radiotherapy(CCRT) and had complete response from March 1, 1995, to March 31, 2012. Results : Of the recurrent NPC patients, patients received 2nd line chemotherapy had more recurrence within 2 years(p=0.010). Especially, patients received 2nd line chemotherapy longer than 4 months tend to have recurrence early(p=0.035). Other factors are not different between recurrent and non-recurrent NPC patients. Conclusion : The presence and the duration of 2nd line chemotherapy are associated with early recurrence.

Bilateral chylothorax as a complication of radical neck dissection is extremely rare. Early diagnosis of chylothorax is important due to the consequences on metabolic & cardiopulmonary conditions. This present report describes our recent experiences with two cases of bilateral chylothorax following left modified radical neck dissection that was treated successfully by conservative management.

Neck trauma is a relatively uncommon but can be a life-threatening injury. Several guidelines for neck trauma is established to recommend a proper management such as no clamping of bleeding vessels, no probing of wounds, Trendelenberg position for preventing venous air embolism. Here, we present a regretful case of 49-year-old man with neck trauma presenting undesired bleeding after probing of wound, and then discuss about treatment guildeline for neck trauma with a review.

It is important to choose which approaches should be used to correct the fracture if the operation is indication for surgery in patients with orbital floor fracture. Transorbital, transantral, and endonasal approaches are methods for correcting the orbital floor fracture. The approach needs to be considered the location of the fracture, the degree, the severity of the fracture, the least remaining patient's disability, and preference of the surgeon. We report a case of orbital floor fracture using transorbital approach and endonasal catheter ballooning to resolve the limitations of transorbital approach alone.

Background and Objectives: This study aimed to analyze the features of patients with papillary thyroid carcinoma (PTC) recurred as distant metastases (DM). Materials and Method: We retrospectively reviewed and analyzed clinical records of 63 patients who were treated for PTC recurred as DM between 2000 and 2006. Univariate and multivariate analyses of various clinical factors were performed. Results: Male patients were 12, and female patients were 51. The 5- and 10-year survival rates for PTC recurred as DM were 85% and 73%, respectively. Size of tumor, multiplicity of tumor, lateral neck node metastasis, and RAI ablation therapy with other treatments such as surgery were associated with survival rate (p < 0.005) in univariate analysis. The lateral neck node metastasis[p =0.039, hazard ratio=2.2(95% CI. 1.18~3.24)] and multiple organ DM[p =0.041, hazard ratio=2.18(95% CI. 1.03~2.89)] were related to the survival in multivariate analysis. Conclusion: PTC recurred as DM is uncommon (2.2%). The size of tumor, the multiplicity of tumor, lateral neck node metastasis and RAI ablation therapy with other treatments for DM were revealed as associated factors for the survival. Evaluation of DM should be considered in patients with PTC during long-term follow-up.

Sinonasal malignant tumors comprise less than 1% of all cancers and 3% of all malignant tumors of the head and neck, which explains a lack of large series addressing the clinical characteristics and management of these tumors. Neck node metastasis occurs in only about 7% to 15% of malignant tumors compared with other head and neck cancers. A 90-yr-old woman presented with left palpable neck mass and right nasal mass occupying nasal cavity. Fine needle aspiration biopsy of left neck mass results in metastatic squamous cell carcinoma(SCC). PET/CT shows intense FDG uptake in right nasal cavity with bone invasion. Histopathologic examination of excised lesion in the right nasal cavity revealed SCC. We report here on a primary sinonasal SCC with contralateral lymph node metastasis.

Liposarcoma is the second most common soft tissue sarcoma in adult. The incidence of liposarcoma in the head and neck area is very uncommon. Liposarcoma of the neck usually express non-tender palpable mass. The main treatment of cervical liposarcoma is surgical excision and adjuvant radiation therapy. Herein, we report a case of cervical liposarcoma with the review of literature.

The primary treatment of oral cavity cancer is still surgery. By discussing the surgical treatment of oral cavity cancer, the basic concept of head and neck surgery could be thoroughly reviewed. The oral cavity is defined as the hard palate and the anterior 2/3 of the tongue. With appropriate reconstruction, most defects can be repaired without a significant change in quality of life, unlike in the oropharynx or hypopharynx, where aspiration problems frequently occur. The selection of a surgical approach that can provide an appropriate field of view to obtain a resection margin of 5 mm or more has become the core of head and neck surgery. The role of prophylactic neck dissection is also well established in oral cavity cancer patients. Mandibulotomy for access to the oral cavity or mandibulectomy due to cancer invasion requires bony surgical techniques, and reconstruction also requires bone tissue reconstruction techniques as well as soft tissue. Therefore, oral cancer surgery is the most important primary area where all techniques of head and neck surgery are mobilized.

Background and Objectives: Gastric acid reflux is known to be the most important cause of contact granuloma. Therefore, anti-gastric acid reflux medication has been used as the first line treatment although there are other treatment methods such as surgery or steroid injections. Actually, the role of surgery in the treatment of contact granuloma has not been established clearly. The purpose of this study was to evaluate the effectiveness of surgical treatment for contact granuloma. Materials and Methods: We retrospectively reviewed the medical records of 14 patients who were diagnosed with contact granuloma and treated with surgery from 2011 to July 2016 at Hanyang University hospital. Results: Of 14 patients, 9 (64.3%) were male and 5 (27.4%) were female. The mean age was 53.8 (${\pm}6.1$) years. The main symptoms were voice change followed by globus, dyspnea, and asymptomatic. Mean Reflux Finding Score (RFS) before surgery was 13.5 and mead Reflux Symptom Index (RSI) was 10.4. The causes of surgery were inadequate response to proton pump inhibitor (PPI) in 4 cases, airway obstruction with large granuloma in 8 cases, and differential diagnosis in 2 cases. Of 14 patients, recurrence occurred in 8 (53.3%) patients after surgery. In 8 recurrent cases, 5 patients showed complete remission and 3 patients showed partial remission with PPI medication. Conclusion: The role of surgery in the treatment of contact granuloma might be limited due to high recurrence rate.

Schwannomas originating from the external auditory canal are relatively uncommon whereas they are commonly found in head and neck region. The authors recently experienced a 18-year-old male with a large mass in his right side external auditory canal. The mass was reported as a schwannoma and after the local excision, no symptom or sign of recurrence was identified. We report the case with literatures.
