Video Transcript

Attention is now to elevate the lower skin flap subplatysmally, the lower limit of which is the superior belly of the omohyoid muscle. This lower skin flap is retracted with the help of a skin stitch. The external jugular vein and the retromandibular vein is being dissected and preserved.

The level IIA nodal tissue is seen being dissected off. The spinal accessory nerve is seen being exposed and preserved. The fibrofatty tissue, posterior-superior to the spinal accessory we nerve– that’s the level IIB– is dissected of carefully, without much traction on the nerve.

The superior belly of omohyoid is being delineated, which is the lower limit of dissection. Level IIA tissue is further being dissected. Posteriorly, the dissection is over the plane of the branches of the deep cervical plexus. These branches can be preserved. The dissection is seen here over the deep cervical plexus.

The next step is the sharp dissection with a 15-number surgical blade to separate the tissue of the internal jugular vein. It’s very important to preserve the anterior tributaries of the internal jugular vein.

The specimen is finally being separated off, and that finishes the level II and III neck dissection. The anatomical structures are being demonstrated– the spinal accessory nerve, the internal jugular vein, the anterior tributaries, the deep cervical plexus, and the superior thyroid artery.

The procedure is completed, and the wound closed in layers. A suction drain was kept for drainage.

To summarize, selective neck dissection is done in early-stage oral cancer. It is an elective prophylactic surgical procedure done along with the primary dissection. The video demonstrated the removal of neck nodal levels I, II, and III. Thank you.
