The usage of PAHG inlabial repairs

Objective　Using PAHG to repair vermilion, labial depression, lip defect and leptolips, to try new ways of lip repairs. Methods　23 cases of different degrees of lip defect and labial depression were individually injected with PAGH (type C) into pars labialis and being fully molded. Results　22 cases were satisfactory. 1 case with cheilocace, the PAHG was then aspirated and injected again with no adverse reaction 3 months and 1 year thereafter. The lip has now a good contour and feels soft with normal a sensation. Conclusion　PAHG has fine biological flexibility, with little irritation to tissue. It′s a soft material close to normal and easy to operate, thus a fine filling material for labial defect and deformity.
