Local hatchet flap for facial skin defects reconstruction in special areas.
BACKGROUND: The local hatchet flap has been used to reconstruct skin defects of the face with satisfactory results. Cosmetically, it has advantages over other local flaps when skin defects are located in special areas such as the eyelid. OBJECTIVE: The purpose of this study was to examine the application of local hatchet flaps for facial defect reconstruction, especially in cases where reconstruction is classically difficult for cosmetic and functional rehabilitation. METHODS: We report an illustrated case series. Results. In this study, all four cases achieved satisfactory functional and cosmetic results using the local hatchet flap. CONCLUSIONS: The local hatchet flap is an effective and simple alternative for reconstructing facial defects in special areas of the face, offering good cosmetic results and satisfactory function.

[Rhinoplasty of unilateral cleft lip].
OBJECTIVE: To investigate the technique for unilateral cleft lip nasal deformities. METHODS: Through the traditional columella margin incision, the alar cartilage and the lateral nasal cartilage were exposed. After the mucosa between the two cartilages was divided, a mucosa-cartilage flap was developed and anchored, moving the lateral crus upwardly and medially, correcting the nasal deformity. RESULTS: 52 cases of primary nasal deformities and 18 cases of secondary nasal deformities were corrected with this technique. Satisfactory results were achieved. CONCLUSION: This technique is recommendable, which is more likely to restore the physiological characters of the nose than the conventional technique.

[Reconstruction of partial nose defects with retroauricular free flap transplantation].
OBJECTIVE: To present the operation for nose defect reconstruction using a retroauricular free flap and the auricle cartilage. METHODS: Based on the anatomy and blood supply of the retroauricular region, a flap was designed and harvested with the posterior auricular vessels as its pedicle. The flap was used to repair nose defects in five patients. Of them, three had unilateral subtotal alinasal defects, one had nasal apex defect, and one had defects on nasal apex and bilateral ala. The size of the defect ranged from 2.5 cm x 1.5 cm to 3.0 cm x 4.0 cm. The flap varied between 3.0 cm x 2.0 cm and 4.5 cm x 3.5 cm. In 4 cases, the auricular cartilage of 2.0 cm x 1.5 cm to 1.5 cm x 1.0 cm was taken along with the flap. The posterior auricular vessels were anastomosed with the facial vessels. The donor site was covered with full-thickness skin graft. RESULTS: Postoperatively, the blood supply to the flaps was fairly good in 3 cases, while there was various venous stasis in 2 cases during the first 4 days. However, the postoperative results of the 5 cases were satisfactory. CONCLUSIONS: The retroauricular free flap is a good choice for partial nose reconstruction, which had the merits of well-hidden donor site, good color match, and one-stage operation.

[Computer-aided tissue expansion 3D profilometry and surgery planning system].
OBJECTIVE: To develop and evaluate the computer-aided system in measurement of expanded skin and preoperative planning. METHODS: Stereophotogrammetric technique was used to gain the 3D image-pairs, from which the contours of the expanded sites were restored. The 3D surface data were provided to the specially developed "computer-aided tissue expansion 3D profilometry and surgery planning system", to calculate the expansion area and help the preoperative design. RESULTS: The system has been applied clinically in 16 tissue expansion sites of 11 patients with fairly good results since March 1999. Compared with the traditional method, this system is accurate, repeatable and feasible. CONCLUSION: This technique is useful and promising for improving the operation of tissue expansion.

[The expanded distant skin flap and its application].
OBJECTIVE: To summarize and present the experiences and results of the expanded distant skin flaps used in plastic and reconstructive operations. METHODS: 102 patients who had undergone expanded distant skin flap transfer were reviewed and followed up. RESULTS: Good results were obtained. Especially when there was no sufficient normal skin close to the lesion or defect, the distant skin flaps were employed. The expanded distant skin flap can be directly transferred as a pedicle skin flap or an island skin flap. It can be indirectly transferred with an intermediary carrier or as a free skin flap. CONCLUSION: The expanded distant skin flaps have many advantages, indications, worthy of recommendation.
