Head Radical Limited Edition Review

Overview, Morbidity Associated With Radical Neck Dissection, Events Leading to Modified Neck Dissection. A skin incision is made that optimizes exposure of the neck. The author prefers to use an apron flap design that extends from the mastoid tip to the mandibular symphysis see the first image below. Alternatively, a hockey stick incision can be made. Incisions that result in a trifurcation are less desirable because of the potential for distal flap necrosis and carotid artery exposure. If bilateral neck dissections are planned, the incision extends from one mastoid tip to the other to create a single apron flap see the second image below. The subplatysmal flap is elevated superiorly to the mandibular border and inferiorly to the supraclavicular region. New.

Islamism is a concept whose meaning has been debated in both public and academic contexts. The term can refer to diverse forms of social and political activism. Dissection in a plane that separates the fascia from the underlying platysma facilitates an en bloc approach to the lymphatic structures within an envelope of fascia. The marginal mandibular nerve can be preserved by elevating the submandibular gland fascia as part of the flap or by elevating the flap deep to the common facial vein after dividing it. Flap elevation proceeds posteriorly immediately deep to the subcutaneous adipose tissue back to the anterior border of the trapezius muscle. Care is taken during flap elevation to remain superficial, preserving the greater auricular nerve and the SAN see the image below. The contents of the submental triangle sublevel IA are then elevated from the inferior border of the mandible and the opposite digastric muscle off of the mylohyoid muscle, leaving the overlying muscle fascia intact. Dissection in the proper plane allows for an en bloc elevation of the contents into the submandibular triangle sublevel IB and to the posterior border of the mylohyoid muscle. Retraction of the mylohyoid muscle anteriorly allows for identification of the submandibular duct, which is ligated and divided, and the lingual nerve, which supplies innervation to the submandibular gland. These contributions are divided inferior to the submandibular ganglion. Final Fantasy Type-0 English Patch more. The dissected contents of sublevels IA and IB are then elevated over the digastric muscle in continuity with the nondissected portion of the neck see the images below. Head Radical Limited Edition Review' title='Head Radical Limited Edition Review' />At this time, intraoperative assessment is necessary to determine the proximity andor fixation of lymph node metastases to the IJV, SAN, and SCM. The contents dissected from level I are elevated caudally to visualize the superior internal jugular vein. Retraction of the posterior belly of the digastric with a vein retractor may facilitate exposure. Sacrifice or preservation of the new lymphatic structures usually depends on the size and extent of lymph node metastases at level II, the upper jugular lymph nodes. Identification of the SAN can be performed anterior or posterior to the SCM. However, if the possibility of spinal accessory preservation is in question, anterior identification will more quickly determine whether to sacrifice or preserve the nerve. Posterior to anterior identification also bisects the SCM, preventing an en bloc dissection if RND is necessary. Identification anterior to the SCM requires retraction of the anterior border of the SCM posteriorly in the region of the digastric muscle. Elevation of the fascia from the undersurface of the SCM using electrocauterization or blunt dissection with a hemostat parallel to the SAN can be used to easily isolate the nerve see the image below. Posterior to the SCM, the nerve invariably can be found approximately 1 cm cephalad to the greater auricular nerve as it wraps around the SCM see the image below. The approach is more useful when the surgeon chooses to resect the SCM from the onset of surgery. The relationship of nodal metastases to the IJV, SAN, and SCM is then evaluated. Inspection and palpation are used to assess for IJV thrombosis, encasement of the IJV or SAN, and extracapsular involvement of the SCM. Atraumatic dissection with a small hemostat or finger may facilitate the development of a safe plane of dissection. Such dissection should preserve the thick reactive fibrous tissue encapsulating most nodal metastases. The inability to develop a clean plane of dissection mandates sacrifice of the involved nonlymphatic structure. Furthermore, if evidence of extranodal fixation to the surrounding soft tissues of the neck ie, deep cervical musculature is found, performance of an RND or extended RND must be considered because of the advanced stage of regional metastatic disease present. If the SAN can be preserved, dissection is then continued from its proximity to the IJV posterocaudally to the trapezius muscle, dividing the SCM see the image below. If the SCM is going to be preserved, the SAN must be carefully dissected by identifying the nerve both anterior and posterior to the SCM. Stretching of the SAN must be minimized. Head Radical Limited Edition Review' title='Head Radical Limited Edition Review' />A posterior to anterior dissection is then performed beginning at the anterior border of the trapezius muscle. The posterior triangle contents are elevated in an en bloc fashion off the fascia of the deep cervical musculature, preserving the phrenic nerve and the brachial plexus, located deep to this fascia. The SAN must then be freed from the soft tissues of the posterior triangle and can be carefully retracted away from the region of dissection with a vessel loop or nerve hook. Dissection is continued to the posterior border of the SCM. The posterior triangle contents posterosuperior to the nerve sublevel VB are rotated under the nerve inferiorly. Retraction of the SAN in the posterior triangle can be minimized if dissection of the apex of level V sublevel VA is not required. The posterior triangle contents are dissected from the posterior border and the undersurface of the SCM. If the SCM is being resected, the muscle is bisected and elevated in continuity with the posterior triangle contents. Head Radical Limited Edition Review' title='Head Radical Limited Edition Review' />The superior SCM and the supraspinal posterior triangle may be too bulky to rotate underneath the SAN, requiring removal in 2 pieces. Careful dissection of the supraspinal portion of level II, also known as the submuscular triangle sublevel IIB, is necessary to minimize trauma to the SAN and the IJV. The lymph node bearing fibroadipose tissues in this region are also rotated under the SAN in the same manner that dissection of sublevel VA was performed, up to the lateral aspect of the IJV. At this point, the posterior triangle contents, with or without the SAN and SCM, have been elevated to the lateral aspect of the IJV. If the SCM is being resected, transection is performed below the mastoid tip and above the clavicle as in a RND. The contents of levels II, III, and IV have been elevated after division of the omohyoid muscle. The IJV is once again evaluated. Additional nodal metastases are frequently present in the deep cervical chain immediately adjacent and posterior to the IJV and are also occasionally present deep and posterior to the IJV. These can usually be removed en bloc with the remainder of the dissection in a posteroanterior fashion, sharply incising the fascia of the jugular vein with a scalpel blade using a feather light touch. Previous extensive blunt dissection along the posterior aspect of the IJV prevents elevation of the neck dissection over the IJV. If the IJV requires sacrifice due to metastatic nodal involvement or tumor thrombosis, the vein is ligated and divided superiorly and inferiorly following identification and preservation of the vagus nerve see the image below.
