Carcinoma of the lip is a relatively common malignancy of the head and neck region, accounting for approximately one quarter of oral cavity cancers. Although this form of cancer is generally readily curable compared with malignancies at other head and neck sites, regional metastases, local recurrence, and even death from this disease may occasionally occur.(More)
Various endoscopic thyroidectomy procedures have been designed to minimize visible scarring. However, endoscopic thyroidectomies have some limitations in obtaining adequate surgical views and in the precise manipulations of the endoscopic instrument. Recently, robotic technology has been applied to thyroid surgery. The aim of this study was to determine the(More)
The aim of this study was to compare short-term and long-term sensory disturbance and discomfort after robotic thyroidectomy versus conventional open thyroidectomy. We compared 118 patients who underwent robotic thyroidectomy by a gasless unilateral axillobreast (GUAB) or axillary (GUA) approach with 176 patients who underwent conventional open(More)
Squamous cell carcinoma of the head and neck (SCCHN), which is relatively prevalent in Korea, is believed to be induced by environmental carcinogens and host genetic factors. Accumulating evidence has shown that genetic differences in DNA repair capacity resulting from genetic polymorphism influence the risk of environmental carcinogenesis. We therefore(More)
OBJECTIVES/HYPOTHESIS To evaluate clinical characteristics and possible associated factors of idiopathic sudden sensorineural hearing loss (ISSNHL) in children using univariate and multivariate analyses. STUDY DESIGN A retrospective case series with comparisons. METHODS From January 2007 to December 2013, medical records of 37 pediatric ISSNHL patients(More)
OBJECTIVES XPD is a major player in nucleotide excision repair, which is one of the basic pathways of DNA repair. The objective of this study was to investigate the association of XPD single nucleotide polymorphisms (SNPs) and the risk of squamous cell carcinoma of the head and neck (SCCHN) in Koreans. METHODS We performed XPD +23591G>A and +35931A>C(More)
Voice and swallowing alterations are common complaints after thyroidectomy, even in the absence of laryngeal nerve impairment. However, voice and swallowing functions after robotic thyroidectomy have not been thoroughly investigated. This study compared the functional outcomes for voice and swallowing after robotic thyroidectomy and conventional open(More)
BACKGROUND Glucagon-like peptide-1 (GLP-1) is a gut-derived incretin hormone that plays an important role in glucose homeostasis. Its functions include glucose-stimulated insulin secretion, suppression of glucagon secretion, deceleration of gastric emptying, and reduction in appetite and food intake. Despite the numerous antidiabetic properties of GLP-1,(More)
Alcohol consumption is a major risk factor for squamous cell carcinoma of the head and neck (SCCHN). Alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) are key enzymes in ethanol metabolism. The objective of this study was to investigate the relationships of ADH and ALDH single nucleotide polymorphisms (SNPs) with the risk of developing SCCHN in(More)
OBJECTIVES To evaluate the necessity of preserving the posterior branch of the great auricular nerve during parotidectomy. STUDY DESIGN AND SETTING Forty-six patients undergoing parotidectomy were prospectively analyzed. Twenty-four patients had preservation of the posterior branch of the great auricular nerve; in the remaining 22 patients the nerve was(More)
