Abstract:
Following repairing cleft lip by labial-nasal muscle tension bands reconstruction, our team analyzed six groups of velopharyngeal muscles by Micro-CT scanning and three-dimensional reconstruction, including levator veli palatini muscle, palatopharyngeus muscle, tensor veli palatini, palatoglossus, uvularis and superior constrictor of pharynx. It was found that palatopharyngeus and levator veli palatini cooperate with each other to regulate the movement of the soft palate. The structure around the pterygoid hamulus was a fine pulley-like structure that should not be destroyed easily. The velopharyngeal muscle tension bands were proposed by analyzing the biomechanics and spatial structure of six groups of muscles. The main muscle tension band was composed of palatine aponeurosis and uvularis. The first auxiliary tension band was composed of levator veli palatini and palatopharyngeus. The second auxiliary tension band was composed of the palatopharyngeus and superior constrictor of the pharynx. A new cleft palate repair technique based on reconstruction of the velopharyngeal muscle tension bands was proposed. This new method reconstructed the biomechanical relationship of the three groups of muscle tension bands and protected the structure around the pterygoid hamulus to reduce the damage. Biomechanical simulation of velopharyngeal muscle was realized primarily.
