Well-differentiated Thyroid Cancer No role for elective neck dissection Central compartment, level VI nodal dissection for positive central nodes Modified neck dissection, at least levels II-V for neck metastasis, to include level IIB “Berry-picking” is not indicated. www.intechopen.com is in the superior mediasti-num (Figure 1). Level VI lymph nodes fall within the following boundaries: superior (the hyoid bone), inferior (the sternal notch), lateral (the carotid artery), posterior (the prevertebral fascia), and anterior (the undersurface of the sternothyroid muscles). Baseline demographic analysis revealed that the mean age was 48 .5 years and the mean tumor size on ultrasound was 13 .1 mm (range, 1 to 19) . In terms of morbidity, prophylactic central neck dissection (CND; level 6) in potentially malignant thyroid disease is discussed controversially. Surgically, cervical lymph nodes are divided into 6-7 levels (only 6 according to many authors who exclude the level VII nodes) for staging of carcinoma which would also be the basis for selective neck dissection. The rates of (transient and permanent) hypoparathyroidism and palsy of the recurrent laryngeal nerve (RLN) after “first-step” (FS-)CND are analyzed in this study. ... (LR) rate and thyroglobulin (Tg) serum levels, a trend toward routine dissection, avoiding radioactive iodine (RAI), has been generally reported. An important finding?

This may also be referred to as a functional or selective neck dissection. To date, there is little evidence to support the practice of pCND in patients with DTC undergoing total thyroidectomy. Comprehensive or therapeutic neck dissection involves surgical clearance of Levels 1-V and may either be a radical (RND) or modified (MND) neck dissection. Level VI is the anterior, or central, compart-ment of the neck. Neck dissection operations are classified ac-cording to cervical lymphatic levels … Medical Director of Gross Pathology, The University of Chicago, Nephrectomy (transplant or non-neoplastic), Bladder: Cystectomy or Cystoprostatectomy, Endocervical / Endometrial Curettage or Biopsy, Intraoperative Consultation General Guidelines (Protected), Protected: 2-1-2021 Surg Path Meeting Notes, Protected: 12-1-20 Surg Path meeting and year’s recap, Metastatic carcinoma to lymph nodes (N staging). in the absence of clinically apparent cer-vical metastases when the risk of having oc-cult cervical nodal metastases is thought to exceed 15-20%; or for very limited nodal metastases. It involves the removal of the suboccipital lymph nodes, retroauricular lymph nodes, upper jugular lymph nodes (level II), middle jugular lymph nodes (level III), lower jugular (level IV), and the nodes of the posterior triangle of the neck (level V). Hey, I had a left neck dissection with my TT and maybe it’s because they were able to do it from the central incision, but I didn’t experience any extra pain or numbness on the left side of my neck. Central neck dissection, either elective or therapeutic, is a comprehensive compartmental dissection and is distinguished from “berry picking” of only clinically involved lymph nodes. Central lymph node dissection is a neck level 6 dissection. All thyroid surgeons agree that lymph nodes obviously involved with metastatic thyroid cancer in the central neck should be treated by clearance of these nodes via a central neck dissection at the time of thyroidectomy. The incidence of surgical complications is variable, surgeonand centre-dependent, and correlates with pathological features of the tumour. Thyroid 2012; 22:911. MND preserves SCM and/or XIn and/or IJV. The specimen may be labeled as Level I, as submandibular gland resides in the path of lymphatic drainage in Level I. A 28‐year‐old woman, diagnosed with papillary thyroid carcinoma and lymph node metastasis at right level IV, underwent total thyroidectomy, central neck dissection, and selective neck dissection involving levels III and IV via the transoral robotic approach. Patients should tell their doctor if they begin to feel sick before surgery. Due to improved recurrence rates and survival, therapeutic central neck dissection … Thank you, your email will be added to the mailing list once you click on the link in the confirmation email. In terms of morbidity, prophylactic central neck dissection (CND; level 6) in potentially malignant thyroid disease is discussed controversially. Many neck dissections include submandibular gland (as part of a larger dissection or on its own). Head Neck. Annals of Surgical Oncology . The 2009 American Thyroid Association (ATA) guidelines recommend therapeutic central neck dissection (level VI) at the time of thyroidectomy for all patients with clinically involved lymph nodes.

The types of selective dissections are described below. Papillary Cancer (PTC) Approximately 10–15% of patients with low-risk papillary cancer (PTC) develop palpable local recurrence in the lymph nodes of the neck, and up to 60% in those with high-risk disease. The most important morbidities associated with central neck dissection (CND) consist of recurrent laryngeal nerve damage and hypocalcaemia related to parathyroid hypo-function or to accidental parathyroidectomy. A central neck dissection refers to a neck dissection of level VI nodes in the paratracheal, paraesophageal, and upper mediastinal regions. Level I neck dissection incorporating submandibular gland excision puts this nerve at risk for injury. Share. Copyright © 2021 Elsevier Inc. All rights reserved. Metastases to the regional lymph nodes reduces the 5-year survival rate by 50% compared with that of… In your neck, your lymph nodes are organized into levels (see Figure 1). I had 13 lymph nodes removed from the lower neck lymph node levels so your experience could vary! The description of a central neck dissection should include both the indication (therapeutic vs. prophylactic=elective) and the extent of the dissection (unilateral or bilateral). Arbitrarily establishing the posterior limit of Levels II, III, and IV as 2 cm posterior to the internal jugular vein ensures that the dissection is adequate to remove all of these levels (and some of Level V). Serially section to evaluate for lymph nodes and tumor deposits/lesions. Regardless of the indication for CND, the lower anatomic border of the central compartment, specifically the inclusion or otherwise of level VII, is not always clearly defined in the literature. 2014 Feb. 36(2):286-90. .

The rationale for therapeutic central neck dissection at the time of … With most types of cancer, a lower survival rate is expected when cancer migrates to the lymphatic system. Complications of central neck dissection in patients with papillary thyroid carcinoma: results of a study on 1087 patients and review of the literature. Although therapeutic central neck dissection for clinically apparent disease (cN1a) is widely accepted, there continues to be ongoing debate regarding the role of elective/prophylactic central compartment dissection for clinically node-negative (cN0) necks. The rates of (transient and permanent) hypoparathyroidism and palsy of the recurrent laryngeal nerve (RLN) after "first-step" (FS-)CND are analyzed in this study. Radical neck dissection was performed in 22 patients, selective neck dissection in 29 patients. Measure the gland (intact or aggregate, if fragmented). Cancers in the head and neck region commonly metastasize to If the neck dissection is being done for metastatic salivary-gland-type tumor and there is no known primary, then then whole gland should be submitted. Weisz Shabtay N, Ronen O. central neck dissection for papillary thyroid cancer. Redefining classification of central neck dissection in differentiated thyroid cancer. Br J Surg 100(3): 410-418. Good luck. The superior limit of dissection is the skull base anteriorly and the nuchal ridge posteriorly. Neck dissection was usually performed except for tumors with very small sizes in the upper gingiva; levels of I to III/IV were manipulated for a cN0 neck, and levels of I to V were manipulated for a cN+ neck. Clinically, injury results in loss of taste from ipsilateral anterior two third of the tongue and hypoesthesia or paresthesia of the hemitongue with resultant difficulty with speech and deglutition(4). The recurrent laryngeal nerve and vagus nerves are carefully protected . The central compartment (level VI) of the neck is described anatomically as being bound superiorly by the hyoid bone, laterally by the carotid arteries, anteriorly by the superficial layer of the deep cervical fascia and posteriorly by the deep layer of the deep cervical fascia, inferiorly by the innominate artery on the right and corresponding axial plane on the left. The inferior limit is the clavicle. Transcervical CP Myotomy and Staple-Assisted Diverticulectomy (Open Zenker's) Abdominal Dermal Fat Graft Harvest. Get every new post delivered right to your inbox. Submandibular Gland (tan-yellow lobulated) and Lymph Node Candidates (nodular, brown, at bottom). Refers to the removal of lymph nodes contained in levels I-III. Level VI neck dissection and central neck dissection are terms often used interchangeably to describe surgical excision of all lymph nodes from the hyoid bone to the sternal notch between the carotid arteries, but the addition of the superior mediastinal lymph nodes in compartment VII should be included in the central neck dissection. Measure in 3D, noting any sutures that designate Levels. Modified radical neck dissection removes lymph nodes from levels I to V, but keeps one or more of the following – internal jugular vein, sternocleidomastoid muscle or spinal accessory nerve. Methods Bilateral and unilateral FSCND, i.e., lymph node dissection along the … If grossly positive, submit entirely (if small) or 1 section per cm (if large). The medial (anterior) limit is the … A further Level VII to denote lymph node groups in the superior mediastinum is no longer used. Shopping. So YK, Seo MY, Son YI. If grossly negative, submit the entire node. An ipsilateral central neck dissection involves removal of nodes on the same side as the thyroid cancer, whereas a bilateral CLND would include resection of all lymph nodes found in this central compartment. It is bound laterally by the carotid arteries, superiorly by the hyoid bone, and inferiorly by the suprasternal notch. Supraomohyoid Neck Dissection. Radical Neck Dissection (RND) This procedure was described by Crile in 1906 and later popularized by Hayes Martin in 1957. Level VI lymph nodes include the pretracheal, prelaryngeal, and the bilateral paratracheal lymph nodes. Ipsilateral central neck dissection may be sufficient for tumors measuring 1 cm or less and therefore avoids the risk of complications arising from bilateral central neck dissection [6, 15]. A 28‐year‐old woman, diagnosed with papillary thyroid carcinoma and lymph node metastasis at right level IV, underwent total thyroidectomy, central neck dissection, and selective neck dissection involving levels III and IV via the transoral robotic approach. Dissection will start from level I and will go to level III/IV in Supra omohyoid neck dissection and will include level VI in Anterior compartment dissection. AU - Gill, Anthony J. This includes removal of all central lymphatics from carotid artery to carotid artery and hyoid to sternum/clavicle. Central Compartment Neck Dissection. Refers to the bilateral removal of lymph nodes surrounding the midline visceral structures of the anterior neck – level VI. The lymph nodes include the pre- and paratracheal, pre-cricoid (Delphian) and perithyroidal. Central neck dissection (CND) for the treatment of PTC is needed in patients with advanced primary disease ... With VM, we can perform a more complete LN dissection that includes level VII in the central neck and levels IV and Vb in the lateral neck. It is bound laterally by the carotid arteries, superiorly by the hyoid bone, and inferiorly by the suprasternal notch. An error occurred while retrieving sharing information. It is generally done as an elective neck dissection (END) i.e. However, Koo et al. Level VII lymph nodes are in the compartment inferior to level … Central Compartment Neck Dissection Refers to the bilateral removal of lymph nodes surrounding the midline visceral structures of the anterior neck – level VI. Tap to unmute. This means that some of the information for patients that is available is outdated. Neck dissection refers to the removal of lymph nodes and surrounding tissue from the neck for the purpose of cancer treatment. It is typically performed for carcinoma of the thyroid and may include resection of level VII or upper mediastinal nodes. F. Level VI: Anterior (Central) Compartment Group ..... 28 V. Conceptual Guidelines for ... • Lateral Neck Dissection—Includes Level IIA or Levels IIA & IIB, Level III, and Level IV (Figure 8). Nevertheless, a bilateral central neck dissection was performed in all the 46 cases of the present study, in view of the risk of skip and contralateral metastases [ 34 ]. Giordano D, Valcavi R, Thompson GB, et al. Cervical lymphadenectomy is most frequently classified according to the associated anatomic domain sampled, with central neck and modified radical neck dissections being the most commonly described nodal harvesting procedures for thyroid cancer. Methods. We present the operative procedure of transoral robotic selective neck dissection for papillary thyroid carcinoma. Is routine central neck dissection necessary for the treatment of papillary thyroid microcarcinoma? 2 Classification of Neck Dissections Neck dissection operations are classified according to cervical lymphatic levels that are resected (Figures 1, 2). The levels are identified by Roman numeral, increasing towards the chest. In general, patients should not eat or drink anything (except essential medications) anytime after midnight the night before surgery. Classification. level VI central neck dissection, and ipsilateral jugulocarotid supraclavicular and supraomohyoid compartment dissection (levels III and IV) . Describe size range of nodes, grossly positive nodes, any obvious soft tissue involvement. 16.1). Selective neck dissections: Commonly performed SNDs are illustrated in Figure 2, and include lateral, posterolateral, supra- omohyoid, anterolateral and central … Instead, lymph nodes in other non-neck regions are referred to by the name of their specific nodal groups. Figure 7.9. Separate the dissection longitudinally into THREE levels (II, III, IV), using sutures as your guidelines. Selective: Includes removal of select Levels, with or without anatomic structures such as skin, IJV; Most staging dissections are Selective: Submandibular Gland: Level I; Lateral Neck: Levels II-IV; Central Neck: Level VI (pre/para-tracheal, pre-cricoid (Delphian), perithyroidal) Posterolateral Neck: Levels II-V; Triage. Choi SJ(1), Kim TY, Lee JC, Shong YK, Cho KJ, Ryu JS, Lee JH, Roh JL, Kim SY.

AU - Wang, Laura Y. Level VI was only dissected if metastasis was confirmed by preoperative fine or core needle aspiration biopsy. The surgeon dissects along the anterior surface of the right carotid (shown partially removed for clarity), sweeping the right central nodal packet medially to be removed en bloc with the thyroid. Conclusion: Central neck dissection at a minimum should consist of removal of the prelaryngeal, pretracheal, and paratracheal lymph nodes. The central neck dissection (CND) patients were analyzed as those with or without occult metastases to the central neck compartment. Y1 - 2013/7/1 Neck Dissection Jatin P. Shah Ian Ganly Introduction The single most important factor affecting prognosis of squamous cell carcinoma of the head and neck, the sixth most common cancer worldwide, is the status of the cervical lymph nodes. Lateral Neck Dissection. Refers to the removal of lymph nodes in levels II-IV, along the internal jugular vein. Excludes nodes in Level IA, IB and V. Central Compartment Neck Dissection. Refers to the bilateral removal of lymph nodes surrounding the midline visceral structures of the anterior neck – level VI. Radical neck dissection (RND) involves en-bloc removal of Level I-V lymphatics with the removal of the spinal accessory nerve (SAN), Internal jugular vein (IJV) and Sternocleidomastoid muscle (SCM). The cervical rootlets are skeletonized as the fat and fascia are … Neck dissection is a surgical procedure performed to remove these lymph nodes. The central neck compartment includes Level VI, ... An ipsilateral central neck dissection involves removal of nodes on the same side as the thyroid cancer, whereas a bilateral CLND would include resection of all lymph nodes found in this central compartment. Modified lateral neck dissection, including levels II–IV, was performed only in patients with clinically evident nodal disease in the lateral neck on preoperative ultrasonography, or when ultrasound-guided fine-needle aspiration of a lateral node showed positive results. The central neck includes lymph node levels VI and VII. If no gross lesions are identified, submit 1-2 representative sections of gland. Such nodal groups include: 2 Vigilance is required pre- and intraoperatively to accurately detect clinically evident nodal metastasis requiring dissection. Papillary thyroid cancer (PTC) has the peculiar tendency to spread to central and lateral neck lymph nodes. Neck dissection levels. Lateral and central compartments cervical lymph nodes metastases are common among patients with papillary thyroid carcinoma (PTC). insisted on bilateral central neck dissection due to the relatively high rate of occult contralateral central lymph node metastasis (34.3%), especially in multifocal primary tumors and when there is positive lymph node involvement at all lateral neck levels. Not all neck dissections are the same. The incidence of surgical complications is variable, surgeonand centre-dependent, and correlates with pathological features of the tumour. The most frequent metastatic level in the ... the optimal extent of lateral and central neck dissection should include levels II, ... Procedure: prophylactic selective lateral neck dissection Level II, III, IV lymph node dissection... with central neck metastasis (CNM) by performing prophylactic selective lateral neck dissection (SND). This system divides the lymph nodes in the lateral aspect of the neck into five nodal levels, I through V as described below. Please contact site owner for help. The neck is conventionally divided into 6 levels; Level VIIis in the superior mediastinum(Figure 1). Figure 1: Classification of cervical nodal levels (Consensus statement on the classification and terminology of neck dissection. Arch Otolaryngol Head Neck Surg2008; 134: 536–8) Surgical considerations – Posterior limit of Level V neck dissection – Denervation results in shoulder drop and winged scapula 20. Carotid Body Paraganglioma Excision with Level II-III Neck Dissection. with central neck dissection. T1 - Level VII is an important component of central neck dissection for papillary thyroid cancer. The most important morbidities associated with central neck dissection (CND) consist of recurrent laryngeal nerve damage and hypocalcaemia related to parathyroid hypo-function or to accidental parathyroidectomy. In 30-50% of patients with cancer of the thyroid gland, the cancer spreads to the surrounding lymph nodes in the neck.
