Outline of Final Research Achievements

Once facial contracture has established, facial nerve function hardly recover completely. We developed the evaluation method of facial contracture which is sequelae after facial palsy. We use the 3D scanner to evaluate the rise in the cheek and deep nasolabial fold. We analyzed the 3D model of the face and calculate the cheek thickness. We investigated that the differences in the cheek thickness can evaluate the degree of the facial contracture. Botulinum toxin injection shows the temporary relief of facial contracture. We evaluated the effect of botulinum toxin on the facial contracture using the new evaluation method.

Academic Significance and Societal Importance of the Research Achievements

本研究では、顔面神経麻痺の後遺症である顔面拘縮の評価法を開発した。最も不快な顔面拘縮は頬が高くなり、鼻唇溝が深くなる顔面の非対称である。顔面拘縮は発症すれば治療困難とされており、苦しむ患者が多い。評価法が確立していないためその治療法の効果を証明することができない。本評価法で顔面拘縮の程度を評価することができれば、治療法の開発、効果の証明につながり、不快感に苦しむ患者の症状を改善させることができる。
