ABSTRACT

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 alveolar 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 pyriform 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 expansion,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 infection,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.
