[Repair of upper lip defects with an island flap based on the inferior labial arterial arch].

OBJECTIVE: To investigate one-stage repairing upper lip defects with an island flap based on the inferior labial arterial arch. METHODS: An island flap pedicled with the inferior labial arterial arch was used to repair upper lip defects. The size of the wedge-shaped flap ranged from 1.5 cm x 1.5 cm to 1.5 cm x 2.0 cm. Since 1993, fifteen patients with upper lip defects have been treated with this method. RESULTS: All the flaps survived with satisfactory function and appearance. CONCLUSIONS: The island flap of the inferior labial arterial arch is effective and applicable in repairing severe secondary deformities of congenital bilateral cleft lips.

[The function of basic fibroblastic growth factor on revascularization of pearl fat graft transplantation].

OBJECTIVE: To investigate the function of basic fibroblastic growth factor on the survival of fat transplantation. METHODS: Basic fibroblastic growth factor was used in pearl fat graft transplantation on experimental animal models. Microvessels densities both on experimental sides and control sides were quantitatively researched in various periods. The growth course of vessels was observed. RESULTS: Microvessels can be observed clearly. The Microvessels densities both on experimental sides and control sides raised gradually. The density reached highest in 14 days on experimental side and in 28 days on control side, and fell down slightly later. The densities on every experimental sides were higher than that on control sides. CONCLUSIONS: Basic fibroblastic growth factor can effectually accelerate the growth of blood vessels in pearl fat graft.

[The expression of EST and ER in hemangioma with its clinical value].

OBJECTIVE: To study the relationship between estrogen and the development of hemangioma. METHODS: The expression of EST and ER in samples from the thirty-eight cases of hemangioma and six cases of normal control group was examined with the immunohistochemical steptavidin peroxidase conjugated method (SP method). RESULTS: The EST in capillary hemangioma expressed significantly higher than in the cavernous hemangioma, the racemose hemangioma or the control group. Although the EST in cavernous hemangioma and racemose hemangioma also expressed higher than in the control, there are no statistical differences among them. The ER only expressed in some cases in the capillary hemangioma group. No sexual difference was shown in the expressions of the EST and the ER. CONCLUSION: This study shows that there may be a relationship existed between the estrogen and the capillary hemangioma. It may indicate that some capillary hemangioma may be possibly treated by the drugs.
