We report here a patient with a massive lymphatic metastasis involving the internal jugular-subclavian venous (IJ-SCV) junction that was safely resected with a new surgical procedure without significant complications. The patient, a 57-year-old man, had advanced hypopharyngeal cancer that had metastasized to the left IJ-SCV junction with a considerable invasion of the vessels, seemingly precluding a conventional surgical intervention. We, therefore, devised a new minimally invasive surgical approach involving resection of the margin of the medial clavicle, which provided an open view of the operation field. Read More

<b>Introduction:</b> Tumors of large salivary glands constitute about 2-3% of all head and neck tumors. Their incidence is statistically greater in males than in females, with the first symptoms usually appearing between the 4th and 7th decade of life. <br/><b>Aim:</b> The aim of the study was to assess the usefulness of the new classification proposed by European Salivary Gland Society (ESGS) in comparison with the divisions of procedures previously valid in the literature, making a retrospective analysis of patients operated on due to benign tumors of large salivary glands in the Department of Otolaryngology, Head and Neck Oncology of the Medical University of Lodz in 2012-2020.

Objectives: Elective tracheostomy before resection of a malignancy in head and neck region assures unobstructed ventilation during postoperative period but is associated with an increased risk of complications. We aimed to evaluate retrospectively, how application of elective tracheostomy scales would influence frequency of tracheostomy in comparison with preoperative clinical judgement.

Methods: In 205 patients operated from 2013 till 2017 resection of a malignancy involved suprahyoid or pharyngeal muscles, neck dissection and flap reconstruction. Read More

To investigate the feasibility of endoscopic lateral neck dissection via the breast and transoral approaches (ELNDBTOA) for papillary thyroid carcinoma (PTC). From February 2015 to April 2019, 10 patients with PTC (cN1b) including 1 male and 9 females aged from 22 to 53 years old received ELNDBTOA in the General Surgery Department of Zhongshan Hospital, Xiamen University. Total thyroidectomy, the central lymph node dissection and the selective neck dissection (levels Ⅱ, Ⅲ and Ⅳ) were performed endoscopically via the breast approach, and then the residual lymph nodes were dissected via transoral approach.

Objective: The classic skin incision for direct anterior approach (DAA) total hip arthroplasty (THA) is usually placed over the belly of the tensor fasciae latae (TFL) muscle parallel to the axis of the lower extremity. In the "bikini incision" technique however, a more horizontal skin incision is used and placed parallel to the skin creases, which largely corresponds to the skin's tension lines to prevent hypertrophic scarring and optimize cosmetic outcomes.

Indications: Primary or secondary osteoarthritis, femoral neck fracture, aseptic acetabular component loosening with sufficient bone stock and without the need for proximal extension of the approach, head and/or liner exchange. Read More

Background: Eliciting a normal electromyography signal has been the usual method to confirm the functional integrity of the recurrent laryngeal nerve during intraoperative nerve monitoring. Given that oscillations of the vocal cord can be detected with trans-laryngeal ultrasound when the ipsilateral recurrent laryngeal nerve is stimulated with the endotracheal tube in situ, we aimed to compare the accuracy and cost of this novel method with the conventional electromyography method.

Methods: Consecutive patients who underwent elective thyroid, parathyroid or neck dissection procedures were included. Read More

A dense bridge-like tissue named the myodural bridge (MDB) connecting the suboccipital muscles to the spinal dura mater was originally discovered in humans. However, recent animal studies have revealed that the MDB appears to be an evolutionarily conserved anatomic structure which may have significant physiological functions. Our previous investigations have confirmed the existence of the MDB in finless porpoises. Read More

The aim of this study was to explore the correlation between ultrasound-guided fine-needle aspiration cytology(US-FNAC) combined with BRAF V600E mutation analysis and central neck lymph node metastasis in cN0 papillary thyroid cancer, so as to provide reliable molecular evidence to use it for preoperative evaluation, operation procedure design, and postoperative follow-up planning in clinic. Specimens were obtained from 250 patients with cN0 thyroid cancer (TI-RADS≥4a, highly suspected of PTC by US-FNAC) after bilateral thyroidectomy and central neck lymph node dissection with accessible postoperative pathologic results of PTC and central neck lymph nodes and used for cytological diagnosis by H&E stain and BRAF V600E mutation detection. Single-factor analysis showed that differences between the central neck lymph node metastasis and nonmetastasis groups were statistically significant in gender, BRAF V600E mutation, and extracapsular extension.

The health problems caused by the frequent relapse of papillary thyroid carcinoma (PTC) remain a worldwide concern since the morbidity rate of PTC ranks the highest among thyroid cancers. Residues from contralateral central lymph node metastases (con-CLNM) are the key reason for persistence or recurrence of unilateral papillary thyroid carcinoma (uni-PTC); however, the ability to assess the status of con-CLNM in uni-PTC patients is limited. To clarify the risk factors of con-CLNM, a total of 250 patients with uni-PTC who underwent total thyroidectomy and bilateral central lymph node dissection were recruited in this study. Read More

Neck dissection is a surgical procedure reserved for thyroid cancer cases with clinically evident lymphatic invasion. Although neck dissection is a reliable and safe procedure, it can determine a significant morbidity involving a variety of structures of nervous, vascular and endocrine typology. A careful pre-operative study is therefore essential to better plan surgery. Read More

The impact of the extent of parotid surgery on postoperative complications has long been considered a topic of controversy. The aim of the current network meta-analysis (NMA) is to answer the following questions: (1) Does the extent of surgical resection of benign parotid tumors increase the risk of postoperative complications? (2) What is the best surgical intervention for treatment of benign parotid tumors that can provide an acceptable balance between tumor recurrence rate and other postoperative complications? A comprehensive search on PubMed, Embase, Scopus, and Cochrane library was conducted to identify the eligible studies. The outcome was the incidence of tumor recurrence, facial nerve weakness (temporary [TFW] or permanent [PFP]), Frey's syndrome (FS), sialocele, and salivary fistula. Read More
