Reconstructive surgery is, in its broadest sense, synonymous with plastic surgery. Commonly, however, reconstructive surgery is understood as the use of surgery to restore the form and function of the body, which does not include aesthetic or plastic surgery. For example, plastic surgeons, maxillo-facial surgeons, and otolaryngologists do reconstructive surgery on faces after trauma and to reconstruct the head and neck after cancer. Reconstructive surgery represents a small but critical component of the comprehensive care of cancer patients. Its primary role in the treatment of cancer patients is to extend the ability of other surgeons and specialists to more radically treat cancer, offering patients the best opportunity for cure. Peer review is the evaluation of work by one or more people with similar competencies as the producers of the work (peers). It functions as a form of self-regulation by qualified members of a profession within the relevant field. Peer review methods are used to maintain quality standards, improve performance, and provide credibility. In academia, scholarly peer review is often used to determine an academic paper's suitability for publication. Peer review can be categorized by the type of activity and by the field or profession in which the activity occurs, e.g., medical peer review.
