[Medical-legal evaluation of laryngeal dysfunction to determine disability]. / Valutazione medico-legale delle disfunzioni laringee in ambito di invalidità civile.

ABSTRACT

The "New Table indicating the percentage of disability resulting from injury and disabling diseases" approved by the Italian Ministerial Decree dated February 5, 1992 gives a superficial, highly disorganized handling of laryngeal pathologies. This Table only considers phonatory function disorders which are included in a special section; it totally neglects dyspnea and dysphagia of laryngeal origin. This omission cannot even be overcome on the basis of similarities since there are no analogous items listed for reference. In fact, the parameters applied to evaluate dyspnea (CV, VEMS, O2 consumption) apply to ventilation disorders of a pulmonary nature and cannot, therefore, be used in cases of laryngeal dyspnea. Moreover, the Table does not deal with dysphagia at all. In addition, the basis for the Table--the concept of permanent functional damage--is not always adhered to in giving indications for evaluation of phonatory tract damage. The purpose of the present work is not, however, to propose a different way to determine the percentages for the individual items in the tables; rather, the aim is to suggest a different, highly standardized procedure for evaluating laryngeal dysfunctions which is easy to apply.
