Korean Society of Thyroid-Head and Neck Surgery appointed a Task Force to provide guidance on the implementation of a surgical treatment of oral cancer. MEDLINE databases were searched for articles on subjects related to "surgical management of oral cancer" published in English. Results were restricted to systematic reviews, randomized control trials/controlled clinical trials, and observational studies. The quality of evidence was rated with use RoBANS (Risk of Bias Assessment Tool for Nonrando

BACKGROUND AND PURPOSE: A higher CHADS(2) score or CHA(2)DS(2)-VASc score is associated with an increased risk of ischaemic stroke in patients with non-valvular atrial fibrillation (NVAF). However, there are no data regarding early neurological outcomes after stroke according to the risk levels. METHODS: In this study, a total of 649 stroke patients with NVAF were enrolled and categorized into three groups: low-risk (CHADS(2) score of 0-1), moderate-risk (CHADS(2) score 2-3), or high-risk group

BACKGROUND: Recently, the modified facelift incision (FLI) has gained increasing popularity for its cosmetic benefits in parotidectomy. However, many surgeons remain concerned with the adequacy of the exposure and are unwilling to use the FLI for anterior or superior tumors of the parotid gland because these tumors are closer to the superficially positioned facial nerve branch. To evaluate the changing trends in parotidectomy incisions for benign lesions at a single institute, and to compare the

Reconstruction of tracheal defects is one of the most difficult procedures in head and neck surgery. To date, various reconstructing techniques have been used with no consensus on the best approach. This study investigated the feasibility of using a fibrin/hyaluronic acid (HA) composite gel with autologous chondrocytes for tracheal reconstruction. Chondrocytes from autologous rabbit auricular cartilages were expanded and seeded into a culture dish at high density to form stable tracheal cartilag

OBJECTIVE: The pulsed dye laser (PDL) has been shown to be effective in the treatment of hypertrophic scars and keloids in dermatology. On the basis of histopathologic similarities between sulcus vocalis and scar tissue and numerous reports on the treatment of laryngeal lesions, especially scar tissue, with PDL, we evaluated the efficacy of treating sulcus vocalis with PDL. We named this surgical procedure PDL glottoplasty. STUDY DESIGN: Case series with planned data collection. SETTING: A unive

Reconstruction of trachea is still a clinical dilemma. Tissue engineering is a recent and promising concept to resolve this problem. This study evaluated the feasibility of allogeneic chondrocytes cultured with fibrin/hyaluronic acid (HA) hydrogel and degradable porous poly(L-lactic-co-glycolic acid) (PLGA) scaffold for partial tracheal reconstruction. Chondrocytes from rabbit articular cartilage were expanded and cultured with fibrin/HA hydrogel and injected into a 5 × 10 mm-sized, curved patch

Retropharyngeal lymph node (RPLN) metastases can occur from advanced head and neck malignancies. Surgical access to RPLNs can be challenging. Considering the more aggressive conventional approach methods, there is an increasing need for minimally invasive techniques. Applying transoral robotic surgery (TORS) to access the RPLN has never been reported in the literature. The purpose of this study was to describe our experience with transoral robotic RPLN dissection for oropharyngeal and hypopharyn

PURPOSE: To examine the feasibility of endoscopic thyroidectomy (ET) via an axillo- breast approach without gas insufflation for large thyroid tumors and micropapillary carcinomas. MATERIALS AND METHODS: The patients in the benign group were separated into groups 1 (n=95, <4 cm in tumor diameter) and 2 (n=37, ≥4 cm in tumor diameter). Also, 57 patients in the micropapillary carcinoma group underwent an endoscopic hemithyroidectomy (HT) (group 3) and were compared with 60 patients who received co

Carcinoma ex pleomorphic adenoma (CEPA) is a rare, aggressive, poorly understood malignancy. In CEPA, an epithelial malignancy develops in association with a primary or recurrent benign pleomorphic adenoma. Carcinoma ex pleomorphic adenoma is very difficult to identify before surgery because the clinical presentation of many cases is similar to that of pleomorphic adenomas. The risk for malignancy increases with the duration of a mixed tumor. Treatment of CEPA must be individualized on the basis
