MUNOZ-DIAZ, Alicia et al. Myofunctional therapy, malocclusion and orofacial dysfunction: Profile photogrammetric evaluation. Int. j interdiscip. dent. [online]. 2021, vol.14, n.3, pp.229-232. ISSN 2452-5596.  http://dx.doi.org/10.4067/S2452-55882021000300229.

This analytical observational study aimed to determine the effect of Myofunctional Therapy on the facial profile in volunteers with malocclusion and orofacial dysfunction, through photogrammetry. Fifteen patients were recruited, and the following cephalometric variables were measured indirectly through photogrammetry in the Blue Sky Plan Software (Blue Sky Bio®): Nasolabial Angle, Lip Prominence and Aesthetic Plane. Previous photographs were taken, at the beginning of Myofunctional Therapy (first session) and the end (tenth session). To compare the values of each variable in a volunteer between the beginning and end of therapy, statistical analyses were performed. There was no statistical difference in the values obtained in any of these variables when comparing the beginning and the end of myofunctional therapy. Therefore, it was concluded that myofunctional therapy does not have a statistically significant effect on these facial profile variables in volunteers with malocclusion and orofacial dysfunction measured by photogrammetry, despite the functional changes perceived by patients and evaluators. However, it is essential to perform a rigorous diagnosis and subsequent referral to speech therapy, if applicable, to achieve functional balance in the patients and reduce progression or recurrence risk of Dentomaxillary Abnormalities.
