这项前瞻性纵向研究评估了下颌前移手术后3D软组织的变化。颅底配准用于叠加由锥形束计算机断层扫描(CBCT)体积建立的虚拟模型。计算术前至摘除夹板(4~6周)、术前至术后1年(手术结果1年)、摘除夹板至术后1年(术后适应)的下颌软硬组织移位(n=20)、下切牙移位至术后1年(n=21)。彩色图谱的定性评估显示了手术后的变化和手术后的适应，但只有下唇显示了术后有统计学意义的适应。软硬组织下巴变化在评估的每个时间间隔内显著相关：术前至摘除夹板(r=0.92)，术前至术后1年(r=0.86)，摘除夹板至术后1年(r=0.77)。只有在手术前和术后1年之间，下切牙和下唇之间才有统计学意义的相关性(r=0.55)。术后1年，31%的下唇变化是由下切牙位置的变化引起的，73%的软组织变化是由硬下巴引起的。这项研究表明，3D软组织对下颌前移手术的反应明显不同。
This prospective longitudinal study assessed the 3D soft tissue changes following mandibular advancement surgery. Cranial base registration was performed for superimposition of virtual models built from cone beam computed tomography (CBCT) volumes. Displacements at the soft and hard tissue chin (n=20), lower incisors and lower lip (n=21) were computed for presurgery to splint removal (4–6 week surgical outcome), presurgery to 1 year postsurgery (1-year surgical outcome), and splint removal to 1 year postsurgery (postsurgical adaptation). Qualitative evaluations of color maps illustrated the surgical changes and postsurgical adaptations, but only the lower lip showed statistically significant postsurgical adaptations. Soft and hard tissue chin changes were significantly correlated for each of the intervals evaluated: presurgery to splint removal (r=0.92), presurgery to 1 year postsurgery (r=0.86), and splint removal to 1 year postsurgery (r=0.77). A statistically significant correlation between lower incisor and lower lip was found only between presurgery and 1 year postsurgery (r=0.55). At 1 year after surgery, 31% of the lower lip changes were explained by changes in the lower incisor position while 73% of the soft tissue chin changes were explained by the hard chin. This study suggests that 3D soft tissue response to mandibular advancement surgery is markedly variable.
