[Soft tissue profile changes following surgical correction for Chinese adults with maxillary protrusion].
The soft tissue profile response to anterior maxillary osteotomy for anterior maxillary excess patients was evaluated. Soft tissue change to hard tissue change ratios as well as linear regression equation were calculated from a patient pool representing fifteen anterior maxillary osteotomies. The soft tissue profile response to anterior maxillary osteotomy appeared to be predictable. The results led to the following abbreviated conclusion: posterior movement of subspinale was accompanied by posterior movement of 37% (r = 0.73) at subnasale, 63% (r = 0.87) at superior labial sulcus. Posterior movement of incision superius was accompanied by posterior movement of 75% (r = 0.86) at labrale superius.
