Nutritional deficiencies occurring during treatment process in patients with jaw fractures will have a negative impact as: reducing of immune indicators in the body, weakening of protective reactions, tendency to complications, and traumatic effects. This article summarizes the content of scientific studies related to the nutritional status or nutrition of patients with fractures. Methods: Was conducted a systematic review of randomized controlled trials evaluating the nutritional status of patients with jaw fractures and post-orthodontic surgery during immobilization. Results: Were identified twenty-seven studies. It is established that during the immobilization period the patient has changes of the trophic status, nutritional insufficiency (malnutrition), explained by weight loss and changes in anthropometric parameters, blood changes (hypoalbuminemia, decrease of hemoglobin of blood). Oral nutritional supplements or alternative feeding methods improve nutritional status, as many studies have observed (weight and other anthropometric parameters, normalization of biochemical blood parameters,). In addition, according to some authors, decreased the number of complications and reduced the duration of hospitalization and expenditure. It is recommended that nutritional supplements be offered to malnourished patients during this period.

This review article provides brief information on rehabilitation measures that improve the local and general condition of patients with jaw fractures. In the recent year the number of injuries with maxillofacial trauma has significantly increased in all countries of the world. Among maxillofacial injuries, fractures of the jaws occupy the main place (65- 80%), and most of the patients are young and able-bodied people. Despite the continuous improvement of the treatment methods of jaw fractures, the periods of immobilization and temporary disability are not reduced, and the incidence of inflammatory complications remains high, which significantly worsens the outcome of trauma. This largely depends on the lack of an effective system of rehabilitation of patients and a comprehensive approach to treatment with the use of both, pharmacological, psychotherapeutic, and physical rehabilitation measures. Complex treatment and rehabilitation of patients with jaw fractures will promote rapid stabilization and reduction of posttraumatic manifestations of the disease and, as a result, improve physical and mental health and increase the life potential and the level of their working capacity. The object of the review is to study and combine rehabilitation activities, that improve the health, working capacity and local status of patients with jaw fractures during immobilization and after removal of splints. Materials: The articles were identified using the computerized search engine PubMed, Elsevier, Cochrane Central, Google scholar, Google search, Research Gate, Ebsco Host, dissercat.com, medical-diss. com, cyberleninka.ru and other possible sites with keywords such as maxillofacial trauma, mandibular fracture, jaw fracture intermaxillar fixation and rehabilitation, recovery, physiotherapy, psychology, nutrition, feeding, diet, care, therapeutic gymnastics and in various combinations of these words in Russian and English. And they also took into account the relevant bibliographic lists. Randomized controlled trials, meta-analyzes, prospective clinical trials were selected based on their significance.
