[Advancement of salvage surgery for recurrent head andneck squamous cell carcinoma]
Abstract:
The treatment options and prognosis of recurrent head and neck squamous cell carcinoma are largely determined by site, extent of disease,and previous treatment. Salvage surgery represents the primary curative option when recurrent head and neck squamous cell carcinoma is resectable. The common factors that affect the prognosis of patients undergoing salvage surgery include surgical resection margin pathology, radiation therapy, advanced initial and recurrent tumor stage, and presence of concomitant neck disease. This paper reviewed the advancement of salvage surgery for recurrent head and neck squamous cell carcinoma.

Muscles that Move the Head
The bilateral sternocleidomastoid, or SCM, and the suprahyoid and infrahyoid muscles are significant head flexors. The SCM muscles originate at the sternum and clavicle and attach to the mastoid process of the temporal bone. The SCM contracts bilaterally to bend the head forward, whereas...
Overview of Advanced Functional Groups
Functional groups are groups of atoms with specific chemical properties that occur within organic molecules and are sometimes denoted as “R”. Functional groups can “functionalize” a compound by enabling it to adopt different physical and chemical properties.
