In osteoarthritis of the knee with varus deformity, abnormal stress is concentrated in the medial compartment of the knee joint. A logical treatment must decrease and recenter the force acting on the knee in order to distribute the compressive stresses evenly over the largest possible weight-bearing articular surfaces. This can be attained by an overcorrection of the deformity. The technique of a Barrel-Vault osteotomy is the correction of severe angular deformity of the knee and the reduction of the patellofemoral joint pressure simultaneously by an anterior displacement of the distal fragment. From 1986 to 1989, the authors studied the preoperative clinical status and lpostoperative results in twelve knees(nine patients) who had had a Barrel-Vault osteotomy for combined medial and patellofemoral disease. The total Insall Knee Rating Score improved from a preoperative mean 54.1 to 85.4 Points at the last assessment. The pain component score improved from a preoperative mean 6.6 to 26.2 points at the last assessment. Eleven kness had either no pain or occasional mild pain. The tibiofemoral angle was corrected from a preoperative mean of 4.4 degrees of varus to a mean of 11.2 degrees of valgus at the last assessment.

In this report, we introduce a case of surgical treatment for Stensen's duct stone with ultrasonography. A 49-year-old female patient presented with postprandial swelling in the right infraauricular lesion. Upon confirming the swelling as the Stensen's duct stone on the computed tomography scan, the sialolith was surgically removed using the transcutaneous procedure. Using ultrasonography, we found the exact location of the stone and removed it without any facial nerve injury. The case clearly demonstrated that the Stensen's duct stone canbe removed more easily and safely with ultrasonography.

BACKGROUND AND OBJECTIVES: The aim of this study was to evaluate the treatment outcomes of medullary thyroid carcinoma (MTC) by retrospective data analysis. SUBJECTS AND METHOD: We conducted a retrospective chart review of 17 cases of pathologically proven MTC patients who were treated from 1998 to 2010 at the department of Otolaryngology-Head and Neck Surgery, Kosin University College of Medicine. RESULTS: The mean tumor size was 2.32 cm (0.5-3.4 cm). Seventy-one percent of patients were diagnosed with advanced stage (III or IV) of MTC. We performed RET genetic screening in 8 of 17 patients. Hereditary MTC was found in 3 of 17 patients (18%) and sporadic MTC was found in 14 of 17 (82%). The preoperative assessment of basal serum calcitonin (CT) level was performed in 15 of 17 patents. Eleven patients had elevated basal calcitonin levels (>13 pg/mL). After the operation for MTC, the serum CT levels were elevated in 7 patients. Overall 5-year survival rate was 94%. Normalization of serum calcitonin level was accomplished more frequently in the absence of extra thyroidal invasion (p=0.034), multifocal tumor (p=0.02). CONCLUSION: The initial treatment of MTC is total thyroidectomy with central compartment neck dissection with or without lateral neck dissection. To detect recurrence or metastasis, regular checking of serum calcitonin is necessary. A better knowledge of prognostic factors could improve the management of MTC patients.

Considering the relatively good prognosis of papillary thyroid carcinoma, surgical treatment should be conducted with an adequate method and extent of surgery with minimal complications. The optimal indications and extent of central neck dissection in papillary thyroid carcinoma has been introduced by variable guidelines. However, there have been controversies in several aspects regarding central neck dissection (i.e., prophylactic versus therapeutic, unilateral versus bilateral), which will remain until a large prospective study is completed. Successful management of cervical lymph node metastasis in papillary thyroid carcinoma requires thorough preoperative evaluation, knowledge on adequate indications and extent of surgery and considerations on surgical anatomy. In this article, we reviewed the rationales for optimal central neck dissection in papillary thyroid carcinoma based on recent studies and presented the surgical strategy and skills based on personal experience of a single surgeon.

Hypoparathyroidism is one of the major complications of total thyroidectomy. This complication can occur when the parathyroid tissue is unintentionally removed or the parathyroid vessels is ligated. Early mapping and localization of the parathyroid tissue would be helpful to prevent such unintended complication. The authors introduce the procedures of parathyroid identification with Near-infrared autofluorescence performed in our institution.
