RESUMEN
Objective@#To explore the clinical effect of the multi-point, multi-level suspension as well as fixation using midfacial soft-tissue spaces for midface lifting.@*Methods@#A total of 65 patients with aging midface were admitted at the First Affiliated Hospital of Fujian Medical University from October 2017 to February 2019. Among them, 47 patients underwent primary blepharoplasty and midface lifting. Eighteen patients, including 5 patients with lower eyelid retraction or ectropion after blepharoplasty, underwent secondary midface lifting after blepharoplasty. The preseptal space was separated under orbicularis oculi muscle by palpebral margin incision. The orbicularis retaining ligament and the tear trough ligament were severed through preperiosteal plane. The preseptal space was connected with premaxillary space and prezygomatic space. The malar fat pad and superficial fascia were vertically suspended and fixed on the periosteum of infraorbital ridge by selected medial, middle and lateral points. The orbicularis oculi muscle was suspended and superolaterally fixed at lateral orbital periosteum. Therefore, the midface could be lifted by multi-point, multi-level suspension and fixation.@*Results@#All incision healed in the first stage. Eyelid separation occurred to 1 patient, around 1 month after the operation. Tarsal strip lateral canthoplasty was performed for repair. Local protuberance of lateral lower eyelid occurred to another patient shortly after the operation, but improved after 3 months by lid massaging. No other complication was observed in the rest of the cases. All patients were followed up for 1 to 8 months and the results were satisfactory.@*Conclusions@#It is simple and practicable to utilize midfacial soft-tissue spaces. This method could benefit patient of less trauma, bleeding, and complications, and good clinical effect. It is a good choice for rejuvenation of the midface, especially for secondary midface rejuvenation after blepharoplasty, or complicated with lower eyelid retraction and ectropion.
RESUMEN
With the average life expectancy increasing and a larger percent of the population aging, more patients of an older demographics are undergoing periocular facial rejuvenation procedures. One of the most common procedures performed for periocular rejuvenation is the lower lid blepharoplasty. As interest in this type of surgery increases however, we are seeing more complications associated with this procedure. One of the most common and challenging postoperative complication after this procedure is lower lid retraction. The degree of lower lid retraction can present in a varying range from lateral canthal rounding and scleral show to cicatricial ectropion. Causes of lower eyelid retraction seem to be multifactorial and there are a variety of surgical approaches for correction of lower eyelid retraction. According to the cause and degree of lower lid retraction, the author must incorporate a customized approach for each deformity. In this study, 33 patients had corrective surgery to treat lower eyelid retraction between July 2004 and June 2006. Of these, only one patient presented for primary correction all others were secondary cases. Techniques used to correct lower lid retraction included a midface lift, a lateral canthopexy or canthoplasty, an oculi muscle suspension, or a spacer graft. There was noted improvement in all cases performed, however a mild degree of recurrence was noted in 6 cases. To effectively correct lower lid retraction, the surgeon must have a sound understanding of the anatomy of the lower eyelid. Technically, key essential fundamentals to correcting lower lid retraction include: knowledge of elevating the mid face, anchoring the lateral canthal tendon securely, and proper insertion of the spacer graft. This article presents multiple techniques to correct significant postsurgical lower lid malposition without the use of skin grafts.
