In this video we show a patient affected with larynx cancer (cT4aN2bM0). In this first part of the recording we present the left neck dissection. We performed the neck dissection for levels IIa, also IIb (at the end), III and IV. The possible presence of the thoracic duct stands out.

Right neck dissection levels IIA, IIB, III and IV

Wed, 16 Nov 2022 14:00:22 +0100

In this video we show a neck dissection of the levels IIA, IIB, III and IV.

After cutting the skin, subplatismal flaps are raised. Then, the anterior border of the SCM muscle is identified and the fascia cut. The SCM muscle is skeletonized and the internal jugular vein is exposed. The XI cranial nerve (accessory nerve) is located in the upper third of the SCM muscle. The tissue above the nerve will also be removed in this procedure as the level IIB of the dissection. On the lower limit the omohyoid muscle is identified and preserved, but movilized to be able to remove the tissue below the muscle as the level IV of the dissection. The upper and lower ends of the internal jugular vein are identified and all the tissue on top of the vein is removed. The cervical rootlets are sought, preserved and followed, protecting the scalenes and the phrenic nerve at the floor of the neck.

Right neck dissection levels IIA, III and IV in the context of a salvage total laryngectomy

In this video we show a neck dissection of the ipsilateral levels IIA, III and IV in the context of an N0 laryngeal cancer that it is undergoing a salvage total laryngectomy.

Different incisions can be done, but in this case we used the same incision we later used for the total laryngectomy, which it is a separate incision from the tracheostomy.
