Coulter et al1 reported an unusual case of so-called dysarthria and dysphagia caused by bilateral anterior condylar dislocation. This case calls for remarks about definition, semiology, and anatomicoclinic correlations.
The definition usually accepted for dysarthria is a collective name for speech disorders resulting from disturbances in muscular control over the speech mechanism due to damage of the central or peripheral nervous system, which therefore restricts the term to speech dysfunctions of neurogenic origin.2 The classification of the dysarthrias distinguishes spastic, flaccid, ataxic, hypokinetic, hyperkinetic, and mixed dysarthria.3 Even if coexisting motor disorders of respiration, phonation, articulation, resonance, and prosody may be present, the classification excludes specific effector dysfunction, such as isolated vocal-fold disorders or mandibular dislocation.
