BACKGROUND: The relationship between the number of parathyroid glands preserved and hypoparathyroidism is not well understood. We sought to determine the number of parathyroid glands that need to be preserved to prevent hypoparathyroidism. METHODS: We analyzed 454 patients who underwent total thyroidectomy for papillary thyroid carcinoma. We analyzed the frequency of hypoparathyroidism according to the number of parathyroid glands preserved. RESULTS: Incidental parathyroidectomy occurred in 19.8

OBJECTIVES/HYPOTHESIS: To analyze the clinical features of olfactory neuroblastoma (ONB) and compare the treatment results according to various treatment modalities, and to validate various staging systems. STUDY DESIGN: Retrospective analysis. METHODS: This study included 35 patients with ONB. Treatment consisted of neoadjuvant chemotherapy and radiation therapy (seven patients), traditional craniofacial resection (TCFR, 12 patients), endoscopic craniofacial resection with craniotomy (ECFR, 11

BACKGROUND: The purpose of this study was to evaluate the frequency and pattern of central lymph node metastasis in isthmic papillary thyroid carcinoma (PTC). METHODS: We compared the clinical and pathological data of 45 patients with a single isthmic PTC and 149 patients with a single PTC located in the unilateral thyroid lobe, all of whom underwent total thyroidectomy and bilateral central neck dissection. RESULTS: The rates of clinical, pathologic, and occult central lymph node metastasis wer

OBJECTIVES/HYPOTHESIS: Submandibular gland excision is traditionally performed by the transcervical approach. To avoid or reduce visible scarring and nerve injury, diverse innovative surgical trials have been reported. Here we report a patient who had an endoscopic submandibular gland resection via a hairline incision. METHODS: A 36-year-old woman presented with a right submandibular gland tumor that was found on a routine check-up. The submandibular gland was resected under endoscopic assistanc

BACKGROUND: The aim of this study was to compare short-term and long-term sensory disturbance and discomfort after robotic thyroidectomy versus conventional open thyroidectomy. METHODS: 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 thyroidectomy from April 2009 to June 2011. Postoperative hypesthesia/paresthesia and discomfort of the neck and anterior chest were

OBJECTIVE: To compare the surgical outcomes of robotic selective neck dissection (SND) with total thyroidectomy and conventional transcervical SND with total thyroidectomy. STUDY DESIGN: Case series with chart review. SETTING: University tertiary care facility. SUBJECT AND METHODS: We retrospectively analyzed 66 patients who underwent total thyroidectomy with SND (≥3 levels of II-V) and bilateral central neck dissection for cN1b papillary thyroid carcinoma, of whom 41 underwent conventional SND

BACKGROUND: The purpose of this study was to evaluate the long-term voice function after robotic thyroidectomy in comparison with conventional transcervical thyroidectomy. METHODS: We prospectively evaluated the voice functions of 54 patients with thyroid nodules who underwent robotic thyroidectomy by a gasless unilateral axillary or axillo-breast approach and of 70 patients who underwent conventional thyroidectomy. Subjective voice symptom score (VSS) was evaluated in questionnaires before thyr

Precision medicine is a new therapeutic concept and method emerging in recent years. The rapid development of precision medicine is driven by the development of omics related technology, biological information and big data science. Precision medicine is provided to implement precise and personalized treatment for diseases and specific patients. Precision medicine is commonly used in the diagnosis, treatment and prevention of various diseases. This review introduces the application of precision m

OBJECTIVE: The present study compared the frequency of depressive disorder in patients with thyroid cancer who had undergone thyroidectomy with the frequency in control individuals. STUDY DESIGN: Retrospective population-based cohort study. SETTING: This study used data from the Korean Health Insurance Review and Assessment Service-National Sample Cohort. SUBJECT AND METHODS: A total of 3609 participants with thyroid cancer who had undergone thyroidectomy between 2003 and 2011 were enrolled in t
