Effectiveness of circumoral muscle exercises in the developing dentofacial morphology in adenotonsillectomized children: an ultrasonographic evaluation.

Alterations in the functions of the facial muscle can establish changes in facial skeleton and in the development of occlusion. The effect of mouth breathing on the facial morphology is probably greatest during the growth period. Removal of nasal obstruction, adenoids, and tonsils have not given beneficial results in the reversion of the habit unless intercepted with various muscle exercises. Hence, this study was conducted to ultrasonographically evaluate the effectiveness of circumoral muscle exercises in the developing dentofacial morphology in adenotonsillectomized children.
