Robot-Assisted Total Thyroidectomy with or without Robot-Assisted Neck Dissection in Pediatric Patients with Differentiated Thyroid Cancer.

J Clin Med 2022 Jun 9;11(12). Epub 2022 Jun 9.

Department of Otorhinolaryngology, Severance Hospital, Yonsei University Health System, Yonsei University College of Medicine, Seoul 03722, Korea.

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

Extent of Neck Dissection and Cervical Lymph Node Involvement in Oral Squamous Cell Carcinoma.

Front Oncol 2022 24;12:812864. Epub 2022 May 24.

Clinic for Maxillofacial and Plastic Surgery, University Hospital Frankfurt, Goethe University, Frankfurt Am Main, Germany.

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).

MODIFIED COMPOSITE PLANE FACELIFT WITH EXTENDED NECK DISSECTION.

Facial Plast Surg 2022 May 26. Epub 2022 May 26.

Otorhinolaryngology, Acibadem University, Istanbul, Turkey.

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

Modified nasolabial flap- the nasomentolabial flap: A new arrow in surgeon's quiver.

Oral Oncol 2022 02 6;125:105697. Epub 2022 Jan 6.

BBCI, India. Electronic address:

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
