The study aimed at establishing the prevalence index of facial asymmetry by extraoral clinical examination of orthodontic patients. The group of study included 384 subjects, selected from the patients who required a specialized orthodontic treatment. Facial asymmetry was evaluated by the parallelism of the horizontal planes and deviation of the menton and nasal pyramid. The age, sex and ecological environment from which one came, the type of dentition and of dento-maxillary anomaly were registered for each patient in part. In the experimental group, facial asymmetry was present in 4.7% of patients, menton deviation in 5.7%, and nasal pyramid deviation – in 3.4%. Significant associations were established between facial asymmetry and the type of dento-maxillary anomaly, classes of age and type of dentition. The results obtained indicate that the prevalence of facial asymmetries in orthodontic patients is especially important for the clinician, as the deviations should be established prior to the initiation of any orthodontic – possibly surgical – treatment.
