Traumatic pyriform sinus perforation is a very rare complication of endotracheal intubation. Forced insertion of endotracheal tube can tear pyriform sinus mucosa. Pyriform sinus perforation can result in deep neck infection which may be potentially lethal. We report a case of pyriform sinus perforation secondary to traumatic intubation, which was successfully treated with primary closure.

BACKGROUND AND OBJECTIVES: This study aimed to evaluate the clinical efficacy of sentinel node centered selective neck dissection in patients with early stage tongue cancer (T1T2N0). SUBJECTS AND METHOD: Lymphoscintigraphy was performed for 12 patients, subsequently followed by sentinel node centered selective neck dissection. The location of the sentinel node, pathological confirmation of node metastasis, and follow-up recurrence were analyzed. RESULTS: In total, 19 sentinel lymph nodes were identified. Of these, 18 were located in levels I to III, and one in level IV. After surgery, 3 patients (25%) were diagnosed with neck node metastasis: two experienced sentinel node metastasis and one experienced skipped metastasis. During follow-up, 3 of the 12 patients (25%) experienced recurrence. CONCLUSION: The recurrence of lymph node could be covered with supraomohyoid neck dissection, which indicates that it has superiority over sentinel node centered selective neck dissection in preventing recurrence in T1T2N0 tongue cancer patients.

Congenital sialo-cutaneous fistula arising from the accessory parotid gland is extremely rare. Although the fistula tract can be successfully excised after making a skin incision along the skin tension line around the fistula opening, a facial scar inevitably remains. We here report a case of sialo-cutaneous fistula that was treated with chemocauterization with trichloroacetic acid (TCA). TCA cauterization is an easy and effective option for the treatment of congenital fistula from an accessory parotid gland, especially from the aesthetic point of view.

Heterotopic gastric mucosa tissue is also called gastric choristoma, and this type of lesion can be found anywhere in the alimentary tract. However, gastric choristoma in the pharynx is very rare; only 10 cases of pharyngeal gastric choristoma have been reported in the English medical literature. A 32-yr-old woman was referred to our institution for the evaluation of a large mass that originated from the posterior wall of the oropharynx. The mass did not cause any symptoms except for the occasional sensation of a foreign body. Gadolinium-enhanced T1 weighted imaging showed a 5 cm-sized mass with central enhancement and hypointense portions, yet the radiological diagnosis was not clear. Transoral mass excision was performed with using electrocautery for making the diagnosis and for treating the mass. The microscopic analysis revealed gastric choristoma.

Mandibular metastasis of thyroid carcinoma is extremely rare. We present the case of a 46-year-old woman who had bilateral huge cheek masses that had grown rapidly over several years. Intra-oral mucosal tissue biopsy and imaging work-up including computed tomography scan and magnetic resonance imaging were performed and the initial diagnosis was presumed to be central giant cell granuloma. Incidentally detected thyroid lesions were studied with ultra-sonography guided fine needle aspiration and diagnosed as simple benign nodules. Due to continuous oral bleeding and the locally destructive feature of the lesions, we decided to excise the mass surgically. To avoid functional deficit, a stepwise approach was performed: Firstly, the larger left mass was excised and the mandible was reconstructed with a fibular free flap. The final pathologic diagnosis was follicular thyroid cancer. Postoperative I-131 thyroid scan and whole body positron-emissions-tomography were performed. Right side mass was revealed as a thyroid malignancy. Multiple bony metastases were detected. Since further radioactive iodine therapy was required, additional total thyroidectomy and right side mandibulectomy with fibular free flap reconstruction was performed. The patient also underwent high dose radioactive iodine therapy and palliative extra-beam radiotherapy for the metastatic lumbar lesion. Follicular thyroid carcinoma should be considered as a differential diagnosis for mandibular mass lesions.

BACKGROUND AND OBJECTIVES: Diagnosis of thyroid disease requiring surgery and subsequent thyroidectomy may affect patients' emotion and quality of life. The purpose of this study is to evaluate the patients' understanding and concern about the disease and recovery rate after thyroidectomy, and therefore to enhance the satisfaction of hospitalization. SUBJECTS AND METHOD: MethodZZSeventy-seven patients undergoing thyroidectomy in a tertiary hospital from April 2009 to October 2009 were enrolled. Questionnaires were filled out on the admission day, discharge day, and 2 weeks after operation. Questionnaires consisted questions regarding the understanding of the disease, details of concern, recovery rate after surgery, and satisfaction on hospitalization duration. Retrospective chart review was also performed. RESULTS: Many patients (42.9%) acquired their knowledge of thyroid cancer through the internet. The possibility of voice change was the major concern before surgery (46.8%), whereas the major postoperative concern was adjuvant therapy (37.7%). The patient group with higher understanding of the disease showed higher recovery rate than the others at the time of discharge (mean postdischarge surgical recovery 67.4% vs. 55.3%, p=0.01). The patient group with lower understanding wanted longer hospitalization than the other group at discharge (p<0.001). CONCLUSION: Patient education about the thyroid disease may reduce patients' anxiety and therefore may enhance subjective recovery rate and satisfaction of hospitalization.

BACKGROUND AND OBJECTIVES: Cervical metastasis of unknown origin (MUO) comprises 3-5% of all head and neck malignancy. Standardized diagnostic approach is not established and standard treatment regimen is not established either. The purpose of this study was to evaluate diagnostic approaches to detect the primary site in patients with neck mass of metastatic squamous cell carcinoma and analyze treatment modalities and their outcomes as well. SUBJECTS AND METHOD: Of 710 patients who had been diagnosed with squamous cell carcinoma of the head and neck site from Jan. 1992 through Dec. 2005, 73 patients were referred to or visited our clinic regarding the presence of neck mass. With retrospective review of the medical record, the diagnostic approaches were evaluated. Thirty patients, in whom the primary sites were not found after all, were included for analysis of treatments and outcomes. RESULTS: The diagnostic steps that revealed the primary sites were as follows: physical examination in 29 cases (39.7%), conventional imaging (CT or MRI) in 5 cases (6.8%), PET scan in 1 case (1.4%), OPD based directed biopsy in 3 cases (4.1%), and intraoperative directed biopsy in 5 cases (6.8%). Primary sites were not detected in 30 cases (41.1%). Complete remission was obtained in 24 patients, for whom 5-year disease free survival rate was 62.1%. CONCLUSION: Thorough physical examination and directed biopsy are strongly recommended for the diagnosis of MUO, but the diagnostic value of PET scan needs to be followed up with more cases.

BACKGROUND AND OBJECTIVES: Burning mouth syndrome (BMS) refers to a collection of symptoms of patients who complain about burning sensation of their mouths without any specific causes. Although this is not a rare disease, the etiology and effective treatment are not well established. We tried to compare the efficacy and side effects of the agents that are reported to be relatively effective to BMS. SUBJECTS AND METHOD: Fifty-one patients who were diagnosed as BMS were chosen as candidates. Trazodone, Paroxetine, Clonazepam, and Gabapentin, which were known to be effective medicines for BMS in previous research were prescribed randomly. We prescribed medication for two weeks and evaluated patients for the effect and side effects at the end of the treatment. The medication was prescribed for 2 more weeks and the patients were evaluated again. RESULTS: Three of 11 (27.3%) patients were prescribed Trazodone, 8 of 12 (66.7%) Paroxetine, 8 of 14 (57.1%) Clonazepam and 12 of 14 (85.7%) Gabapentin. Q showed improvements after 4 weeks of medication. The differential effectiveness among the medications was not significant, except for the inferiority of Trazodone. Five of 11 (45.5%) patients who had been prescribed Trazodone, 2 of 12 (16.7%) who had been prescribed Paroxetine, 2 of 14 (14.3%) who had been prescribed Clonazepam, 2 of 14 (14.3%) who had been prescribed Gabapentin complained of side effects during 4 weeks of medication. CONCLUSION: We can expect high success rates of treatment for burning mouth syndrome with Paroxetine, Clonazepam and Gabapentin. A further study for long term outcomes and side effects in large groups is warranted.

Reconstruction with free flaps has become the choice of reconstruction for most patients with head and neck defects. However, pedicled flaps, such as pectoralis major pedicled flap and latissimus dorsi pedicled flap (LDPF), can also be used instead in selected patients. We performed LDPFs in 6 patients from November 2007 to September 2009. Five of the patients were females with either vascular diseases or large skin defects, or they were highrisk old patients. One male patient received LDPF as a salvage after tongue reconstruction with a free flap failed. Various types of head and neck defects were effectively managed with LDPF without complications. LDPF can be one option for head and neck reconstruction especially in patients who may hve high risk in undergoing free flap reconstruction.

Ion channels in carcinoma and their roles in cell proliferation are drawing attention. Intracellular Ca2+ ([Ca2+]i)-dependent signaling affects the fate of cancer cells. Here we investigate the role of Ca(2+)-activated K+ channel (SK4) in head and neck squamous cell carcinoma cells (HNSCCs) of different cell lines; SNU-1076, OSC-19 and HN5. Treatment with 1 microM ionomycin induced cell death in all the three cell lines. Whole-cell patch clamp study suggested common expressions of Ca(2+)-activated Cl- channels (Ano-1) and Ca(2+)-activated nonselective cation channels (CAN). 1-EBIO, an activator of SK4, induced outward K+ current (ISK4) in SNU-1076 and OSC-19. In HN5, ISK4 was not observed or negligible. The 1-EBIO-induced current was abolished by TRAM-34, a selective SK4 blocker. Interestingly, the ionomycin-induced cell death was effectively prevented by 1-EBIO in SNU-1076 and OSC-19, and the rescue effect was annihilated by combined TRAM-34. Consistent with the lower level of ISK4, the rescue by 1-EBIO was least effective in HN5. The results newly demonstrate the role of SK4 in the fate of HNSCCs under the Ca2+ overloaded condition. Pharmacological modulation of SK4 might provide an intriguing novel tool for the anti-cancer strategy in HNSCC.
