目的：为进一步了解带蒂颊脂垫组织瓣的应用解剖及无覆盖颊脂垫在口腔内的愈合过程。方法：作者在尸体解剖和活体观察的基础上总结颊脂垫组织瓣的解剖特点，通过对用该组织瓣修复腭部缺损的６３例平均术后４年８个月的追踪观察，并对颊脂垫移植后的愈合过程进行了组织学观察。结果：口腔内无覆盖颊脂垫移植２周后开始逐渐上皮化，６～８周完成上皮化过程，再生的粘膜呈粉红色，类似于正常的口腔粘膜，５０％的病例愈合后粘膜存在轻度瘢痕。结论：该组织瓣血供丰富，解剖恒定，易于切取，供区与受区邻近，供区隐蔽，不影响外观及功能，为口腔内软组织缺损提供了一种新的修复方法。
OBJECTIVE: To further understand the anatomic application of the pedicled buccal fat pad tissue flap and the uncured buccal fat pad healing process in the oral cavity. Methods: The autopsy and biopsies were used to summarize the anatomical characteristics of buccal fat pad tissue flap. By tracing 63 cases of palatal defect repaired with tissue flap for 4 years and 8 months after operation, Histological observation of healing process after fat pad transplantation. Results: The buccal fat-free pad in the oral cavity began to become epithelialized after 2 weeks of transplantation. The epithelialization was completed in 6 to 8 weeks. The regenerated mucosa was pink, similar to the normal oral mucosa, and the mucosa was mild in 50% of the cases Degree of scarring. CONCLUSION: The tissue flap has abundant blood supply, constant anatomy and easy to be cut off. It provides a new repair method for soft tissue defect in the oral cavity.
