The concept of functional surgery of the vocal cord was officially introduced in 2000 3 . Considering that most glottic tumors do not go beyond the depth of the vocal ligament it was deemed that the subperichondrial cordectomy systematically carried out for all T12 tumors was overtreatment in most cases. Endoscopic laser surgery takes this consideration into account and classifies cordectomies according to the depth of resection programmed for the various degrees of tumor infiltration. The result is a lower morbidity rate and often much less accentuated dysphonia. 1. Olofsson J 1974 Growth and spread of laryngeal carcinoma. Can J Otol 3 446-459 2.

It is usually exposed in demolitive surgery of the pharynx or in the drainage of retropharyngeal lymph node stations Anatomic Layout The prevertebral plane is exposed on exeresis of the median region viscera. Said plane is bounded laterally by the transverse processes of the cervical vertebrae superiorly by the occipital bone and inferiorly by the first thoracic vertebra. The region consists of a slender musculoapo-neurotic layer covering the cervical column. The most important structures are the cervical sympathetic chain and the vertebral artery which cross the region from top to bottom Fig. . Significant anatomical structures cervical sympathetic chain vertebral artery deep cervical fascia. .
