Resumo
Background: Patients with Long Face Syndrome and class II occlusion are recognized by the antero-posterior mandibular deficiency and excess of vertical growth of the middle third and maxilla. These patients are commonly diagnosed with Obstructive Sleep Apnea Syndrome (OSAS) and presents severe condylar resorption. There is a clinical perception that these morphological changes are present, but there are no studies correlating these data.
Objectives: To analyze the morphological alterations in patients diagnosed as having Long Face Syndrome and test the hypothesis that there is a statistically significant relationship between OSAS, joint disc displacement and temporomandibular joint (TMJ) arthrosis in this group of patients.
Methods: Were analyzed, with computed tomography and magnetic resonance, airway volume, presence or absence of apnea, presence of anterior disc displacement, vertical maxillary excess, mandibular retrusion, mandibular angle variation and anteroposterior deficiency of the chin of de patients who presented the clinical diagnosis of Long Face Syndrome and compared with class I and III patients, between the period of 2013 to 2017.
Findings: Was observed that the anterior disc displacement, condylar resorption and presence of OSAS have a significant statistic correlation with the Long Face Syndrome.
Conclusion: There is a strong correlation of this clinical characteristics and changes related to Long Face Syndrome widening the Long Face Syndrome concept previously described.
