摘要
目的探讨膨体聚四氟乙烯(e—PTFE)行鼻基底填充矫正面中部凹陷的疗效及安全性。方法在面部43/34上方前庭沟处沿齿龈沟切开右43/左34黏膜直达上颌骨骨膜下,然后根据面中凹陷的范围向内和两侧行骨膜下分离,内侧分离至近前鼻棘和梨状孔侧缘,两侧分离范围与术前标记相同,稍大于假体,然后将已雕刻好的一侧弧度与鼻翼弧度相符合的三角形膨体假体行骨膜下植入,沿梨状孔边缘弧度放置,并固定假体,视外观满意后逐层缝合切口。结果69例随访6个月以上,切口均为一期愈合,无感染及假体外露等并发症,面部表情自然,填充效果满意。结论对于无需截骨手术矫正的面中部凹陷,用e—PTFE填充鼻基底,操作简单,术后效果良好。
Objective To investigate the effect and safety of PTFE filling on correction of nasal basal treatment of midfacial sag. Methods Top of the vestibular sulcus groove was cut along the alve olar mucosa under direct maxillary periosteum, and then face inward in depression and the side line of the scope of subperiosteal separation from near to the medial nasal spine and the lateral side of pyri form aperture; range of separation was the same of both sides as marked before operation, slightly larger than the prosthesis; then the arc being carved, which was consistent with the nasal triangle ex pansion, was implanted into sub-periosteal site along pear-shaped arc edge of the hole placement and the prosthesis was fixed; as the appearance was satisfied, the incision was sutured. Results Clinical follow-up lasted for 6 months, and all the wound healing was well in primary intention without infec tion, implant exposure and other complications and facial expressions were natural. The filled results were satisfactory. Conclusions For correction of midfacial depression without need of osteotomy, nasal application of PTFE filling is simple with good efficacy and it is worth promoting.
