[Eye socket reconstruction with free flap].

OBJECTIVE: To discuss the effect of eye reconstruction with free flap. METHODS: Free flap was used in 21 patients of contracted eye socket and anophthalmos. The forearm free flap was utilized in 19 patients,the scapular flap in 2. Free flap with microvascular anastomoses was transferred into contracted eye socket. And hydroxyapatite implant was selectively inserted for intraorbital implantation according to the extent of contracted eye socket postoperation. Eye socket was reconstructed in one stage operation. RESULTS: The flaps were transferred successfully in all patients. All patients were followed up between 4 to 42 months, better cosmetic results were achieved and well-fitted eye prosthesis was weaned. CONCLUSION: Free flap is a useful alternative in treatment of severe contracted eye socket.

[Management of blood vessels in the vascularized autogenous submandibular gland transfer for severe keratoconjunctivitis sicca].

OBJECTIVE: To summarize the management of blood vessels in the transfer of vascularized autogenous submandibular gland. METHODS: Sixty-eight cases of vascularized transfer of autogenous submandibular gland for severe keratoconjunctivitis sicca performed from August 1999 to April 2004 were reviewed. Data collected for each patient included general items, donor and recipient vessels, vessel crisis, salvage of the vessel thrombosis, and survival of transferred glands. RESULTS: Among the 68 cases, all the donor and recipient arteries were facial artery and superficial temporal artery respectively. For donor veins, 55 were facial veins, 1 was vein near the duct, and 12 were venae comitantes of facial artery. For recipient veins, 62 were superficial temporary veins and five were veins in the upper neck, one was deep temporary vein. Vessel thromboses occurred in 10 cases, 9 were venous and 1 were arterial. The salvage rate was 10.0%, with the overall survival rate of 86.8% of transferred gland. CONCLUSIONS: Variation in venous outflow is common in microvascular transfer of submandibular gland, and anastomosis between venae comitante of facial artery and superficial temporal vein is most dependable. Vessel anastomosis under microscope may reduce the vessel thrombosis rate after operation.

[Eye socket reconstruction with free radial forearm flap in anophthalmic orbital syndrome and contracted eye socket].

OBJECTIVE: To assess the effect of eye socket reconstruction with free radial forearm flap. METHODS: Reconstructive procedures were performed in 7 patients underwent orbital exenteration for malignant tumors and in 9 patients underwent enucleation and postoperative irradiation of the orbit for the treatment of retinoblastoma. These patients were suffered from anophthalmic orbital syndrome and contractive eye socket. A microvascular surgical technique with a free radial forearm flap was adopted. Hydroxyapatite implant was inserted as an intraorbital implantation. RESULTS: All patients were followed up for 6 months to 5 years and good cosmetic results were obtained. A large eye socket was achieved permanently. Artificial eye could be fitted with satisfactory results. CONCLUSION: Free radial forearm flap transplantation offers a useful option for the treatment of anophthalmic orbital syndrome.
