Mécanismes posturaux

Facial envelope, labium superior alaeque nasi morpho-physiologic integration and malocclusion

“…The labium superior alaeque nasi inspiratory posture reveals the muscle tone adopted to shape the pyriform and maxillary incisor-canine supports, and to therefore satisfy the requirements of the most efficient breathing modality; and all the while, the labial mental and lingual soft tissues shape the mandibular alveolardental forms and the chin, and adapt their posture to swallowing and to changes in breathing. The craniomandibular and craniorachidian postures comply with the required oro-nasopharyngeal integration 56 .…”

“…As for the development of shapes associated with the different at rest postures adopted by the facial envelope 56 , it demonstrates the labium superior alaeque nasi integration of the oro-nasal structures of the envelope, which may require consistent treatment. The connection between the shapes of the nostrils and those of the upper lip accompanies the preceding mechanical relationship and in fact suggests that, after a clinical examination, this morpho-physiologic integration is at the back of the labium superior alaeque nasi position at rest: a position of simultaneous respiratory intake and nasal valve control, the only active moment of the breathing cycle of the facial envelope, even at rest, engaging all the oral nasal facial skin muscles.…”

Current methods of treating nasal breathing problems in infants and children

“…Why? Because, in many cases breathing malfunction is caused by a nasal disorder, which itself is the cause of the: -hypertrophied pharyngeal lymphoid tissues and not the other way around; -and of a clinically identifiable malfunctioned Oro-nasal malformation 34,35 ( fig. 13).…”

“…The morphological response 15,19,35 to the physiological demands to which the face must incessantly respond are, in the final analysis, the fruit of the postural control exercised by the skin muscles of the oral and nasal openings in the facial envelope. Treatment should be directed toward the goal of restoring optimal nasal breathing, which, in turn, will improve facial posture.…”

“…4). Orthodontists use orthopedic palatal expansion techniques to correct, or better still, to prevent upper anterior crowding and thus restore the transverse labio-nostril support so crucial for dynamic inspiration through a flexible nose and for the postural tonus of the skin covering 35 .…”
