Swallowing disorders: proposal of a method for forensic medicine assessment.

For a correct classification of dysphagia, morphologic instrumental investigations capable of analysing the anatomical structures of the digestive tract, are undoubtedly essential, but the most important investigations are the functional investigations, such as videofluoroscopy, fiberoptic endoscopic evaluation of swallowing, oro-pharyngo-oesophageal scintigraphy, manometry and pH-metry. Results of these examinations enable us to identify, in patients with dysphagia, the extent of permanent damage, as a consequence of injury to the structures designated to swallowing, must be such that it at least minimally impairs and decreases the relative function, but to a degree that can be detected and, in some manner, measured. From a legal point of view, alterations in swallowing, caused by damage to structures belonging to the respiratory-digestive tract, can be found in crimes against persons and particularly in those involving body injury. In the case of civil, but also in private or social insurance proceedings, it is necessary to distinguish which parameters are to be used as reference for evaluating and quantifying the injury in terms of reimbursement. With the introduction of complete biological well-being, injury is considered as an impairment of the worth and right to enjoy psychological-physical integrity as a quality of life. The criteria currently used internationally take into account the conception of psychological-physical efficiency; nevertheless, in Italian forensic medicine, there is no table that offers a thorough quantification of swallowing modifications, if one excludes oesophageal disorders. Herewith, an evaluation table, dividing oro-pharyngo-oesophageal dysphagia into five, progressively serious classes, is proposed.
