The optimal resection extent for papillary thyroid microcarcinoma (PTMC) confined within a unilateral lobe remains controversial. We reviewed the medical records of 132 consecutive patients who underwent total thyroidectomy for the treatment of clinically unilateral PTMC between March 2005 and March 2009. The frequency, pattern, and predictive factors for(More)
OBJECTIVES To investigate the incidence and the risk factors for occult ipsilateral or contralateral central neck lymph node (LN)metastasis in patients with unilateral papillary thyroid carcinoma (PTC) and a clinically negative neck. SUMMARY BACKGROUND DATA Elective central lymph node dissection (CLND) in patients with PTC remains controversial. There(More)
OBJECTIVE Branchial cleft cyst (BCC) is treated surgically using a transcervical approach, leaving potential cervical scars. This prospective study assessed the outcomes of retroauricular hairline incision (RAHI) approach for BCC excision in children. METHODS Twelve patients with second BCC (age < 18 years) underwent cyst excision via the RAHI approach,(More)
The extent of neck dissection (ND) appropriate for necks yielding clinical evidence of metastases of papillary thyroid carcinoma (PTC) is controversial. The need for Ievel IIb lymph node (LN) dissection is particularly uncertain in view of its association with postoperative shoulder dysfunction. In the present study, we examined the frequency, pattern, and(More)
BACKGROUND The extent of lateral neck dissection for clinically evident nodal metastases in the lateral neck in a patient with papillary thyroid cancer (PTC) continues to remain controversial. METHODS We reviewed retrospectively the medical records between March 2005 and March 2008 of 70 patients with PTC who underwent therapeutic lateral neck dissections(More)
CONTEXT Few reports have determined whether preoperative detection of the BRAF V600E mutation in fine-needle aspiration biopsy (FNAB) may influence determination of surgical extent such as prophylactic central lymph node dissection (CLND) in patients with papillary thyroid carcinoma (PTC). OBJECTIVES Our objectives were to investigate whether preoperative(More)
The goal of this study is to determine the clinicopathologic differences in patients with papillary thyroid carcinoma (PTC) with or without chronic lymphocytic thyroiditis (CLT). We reviewed the medical records of 195 consecutive PTC patients who underwent total thyroidectomy and bilateral central lymph node dissection from April 2008 to March 2010. The(More)
Chyle leakage is an uncommon complication of lateral neck dissection for metastatic papillary thyroid carcinoma (PTC). There have been no reports on chyle leakage after central neck dissection not combined with lateral neck dissection. We therefore investigated chyle leakage in PTC patients undergoing thyroidectomy and central neck dissection. A total of(More)
OBJECTIVE The purpose of this study was to investigate the characteristics of pediatric external auditory canal cholesteatoma (EACC). METHODS Chart review of nine children with EACC between January 1, 2000 and December 31, 2007 was performed with subsequent analysis of etiologic factors, associated symptoms, otoscopic findings, imaging features, and(More)
OBJECTIVE To evaluate the effectiveness of topical mitomycin C (MMC) in preventing anterior glottic stenosis (AGS) after transoral microresection of glottic lesions involving the anterior commissure (AC). STUDY DESIGN Prospective clinical study. METHODS Sixteen patients with benign or malignant glottic lesions involving the AC were studied. The lesions(More)
