Pediatric thyroid cancer more frequently develops cervical node metastasis than adult thyroid cancer, even in differentiated thyroid carcinoma (DTC). Thus, cervical neck dissection often needs to be performed simultaneously with thyroidectomy in pediatric patients. Herein, we describe our experience with robot-assisted total thyroidectomy with/without robot-assisted neck dissection in pediatric patients compared with the conventional operated group. Read More

Introduction: Tumor resection combined with neck dissection (ND) or radiotherapy are established methods for the treatment of patients with oral squamous cell carcinoma (OSCC). However, the extent of ND can lead to postoperative complications. Therefore, for the first time, this study aims to identify lymph node involvement in OSCC performed in a bilateral systematic approach based on oncologic board meetings relying on presurgical magnetic resonance imaging (MRI) and computed tomography (CT).

The attenuation of retaining ligaments with aging leads to downward displacement of facial fat compartments, and is responsible for many of the stigmata that occur with aging. The zygomatic cutaneous and masseteric cutaneous ligaments prevent the transmission of adequate traction to the malar portion of the dissection during traditional low SMAS facelift techniques which involve plication or imbrication of the exposed surface of the SMAS because they do not include surgical release of these ligaments. Inadequate release of these ligaments, especially the zygomatic cutaneous ligament may lead to an unbalanced, unnatural appearance with unopposed nasolabial folds. Read More

Purpose: Temporal bone surgery requires excellent surgical skills and simulation-based training can aid novices' skills acquisition. However, simulation-based training is challenged by early stagnation of performance after few performances. Structured self-assessment during practice might enhance learning by inducing reflection and engagement in the learning task. Read More

Background: The recognized pattern of cervical lymph node metastasis (CLNM) of papillary thyroid carcinoma involves a stepwise route. Contralateral lymph node skip metastasis is very rare. In addition, the patient in our case report also suffered from a breast carcinoma accompanied by left supraclavicular lymphadenopathy, which made it difficult to distinguish the origin of the CLNM.

Background: During the COVID-19 pandemic, a multitude of surveys have analyzed the impact virus spreading on the everyday medical practice, including neurosurgery. However, none have examined the perceptions of neurosurgeons towards the pandemic, their life changes, and the strategies they implemented to be able to deal with their patients in such a difficult time.

Methods: From April 2021 to May 2021 a modified Delphi method was used to construct, pilot, and refine the questionnaire focused on the evolution of global neurosurgical practice during the pandemic. Read More

Background: The coronavirus disease 2019 (COVID-19) pandemic substantially undermined medical education and healthcare systems. Owing to the pandemic in South Korea, most medical schools needed to be flexible when conducting online and offline classes, but the guidelines did not reflect the specificity of medical schools. This study described the impact of modified anatomy education schedules at the Seoul National University College of Medicine (SNUCM) on students' academic performance and satisfaction. Read More

Background: Progressive implementation of the milestone competence-based curriculum has created a need for new objective and validated means to assess resident surgical proficiency. A previous systematic review of the literature by our group has highlighted a shortage of tools assessing surgical competence in oncologic procedures in otolaryngology - head and neck surgery.

Methods: We developed a procedure-specific assessment tool for neck dissection using a modified Delphi method. Read More

Purpose Of Review: Although nodal metastasis in thyroid cancer does not have a major impact on outcome, it does have some prognostic implication in adverse metastasis and aggressive histology. The purpose of this review is to discuss evaluation and management of lateral neck nodes in thyroid cancer.

Recent Findings: There is a high incidence of central and lateral neck node metastasis in thyroid cancer. Read More

We report a case of functional recovery following incisional cheiloplasty for the management of lower labial edema that developed after bilateral neck dissection with preservation of the one-side internal jugular vein and postoperative chemoradiotherapy. An 81-year-old woman underwent partial maxillectomy for the treatment of maxillary gingival cancer(squamous cell carcinoma, cT1N0M0, Stage Ⅰ)in April 2013. In July 2013, she underwent bilateral neck dissection(right, modified; left, radical)for bilateral cervical lymph node recurrence with an extra-nodal spread and received postoperative chemoradiotherapy( CDDP 75 mg/m2×3 course and total radiotherapy dosage of 66 Gy).

Aims And Objectives: To describe an inferior extension of a naso-labial flap as an adjunct to a maleo-labial flap in reconstruction of complete thickness defects around the oral commissure in 2 cases that we performed at our institute.

Methods: Two elderly cases of carcinoma buccal mucosa who underwent wide local excision along with neck dissection had moderately large peri-oral defects that are large to cover with nasolabial flap alone. An inferior extension to the maleo-labial flap was added, making it a naso-mento-labial flap to reconstruct the defects with an acceptable outcome aesthetically and functionally. Read More

Background/aim: We compared postoperative radiotherapy (PORT) to surgery only (SO), and supraomohyoidal neck dissection (SOHND) to modified radical neck dissection (MRND) in patients with pT1-T2 squamous cell carcinomas of the oral cavity (OSCC) and a single cervical lymph node metastasis (pN1) in terms of overall survival (OS), oral cancer specific survival (OCSS), and regional recurrence-free survival (RRFS), in a prospective cohort study.

Patients And Methods: We included patients with pT1-T2 pN1 OSCC with no distant metastasis and estimated the survival probabilities using the Kaplan-Meier method and calculated hazards ratios (HR) for PORT vs. SO and MRND vs. Read More
