Background: To explore the feasibility of immediate assessment, which focuses on clinicopathological characteristics of central lymph nodes (LNs) during operation. Moreover, to analyze the predictive effect of various evaluated indicators on the nature, quantities, and ratios of central lymph node metastasis (LNM) in papillary thyroid carcinoma (PTC), to provide the basis for precise individualized central lymph node dissection (LND).
Methods: According to the inclusion and exclusion criteria, 1,271 PTC patients were selected in this cohort study.
Background: The purpose of this study was to investigate the one-stage reconstruction of primary or secondary neoplastic defects in the parotid masseter area.
Methods: Fifty-eight cases of soft tissue defects reconstruction caused by tumors in the parotid masseter area from 2014 to 2018 were analyzed. The minimum area of defect was 4 cm × 5 cm, and the maximum area was 12 cm × 12 cm.
