Smart Surgeon  should be smart anatomist and smart physiologist. This theme seems to be deficient unless immunologist similarly should have good knowledge in anatomy and physiology. The link between surgeon and immunologist is through the anatomy and physiology. Hence the trigon of head neck and spine surgery appeared to be linked to immunology through anatomy and physiology. Among this trigon neck perceive my personal attention, since it got several biologic bearings like terato-biology, structural and functional immunology (Table 1-3) [2-5]. So far the structural immunologic aspects is concerned it served as a niche for tonsils, cervical lymph node and passage way for cervical lymphatics .While for functional immunology it served as stage for natural immune drain for microbial invadors coming from mouth, oropharynx and dental infections as well as tonsils. The draining lymph nodes also drain aberrant overgrowing cancer cells arisen in the neck area.
Neck surgeon inter played real important roles for the immune state of neck area including removal of neoplasms of lymphoid tissues, infective granulomas, chronic cervical lymphadenopathy and space occupying lesions and performing eligible tissue grafting. While the interplay roles of immunologist for the neck region furnishing the basics for mucosal immune function , tissue transplantation, immunology of granuloma,
immune diagnosis for disorders, mechanisms of natural immune drainage of invaders (Table 2-4).
