Reconstructive subperiosteal midface lift: A three nonvisible incision approach.

This article describes our surgical technique for subperiosteal midface elevation in patients with paralytic lower eyelid malposition or cicatricial inferior eyelid retraction. Nineteen patients with paralytic lower eyelid malposition and 15 patients with cicatricial inferior eyelid retraction underwent a subperiosteal midface lift (n = 34). The procedure was performed under local anesthesia through three nonvisible incisions. A transconjunctival incision allows preseptal dissection to the orbital rim, followed by a subperiosteal dissection of the midface. An oral incision is useful to achieve complete subperiosteal dissection and to perform the distal periostomy, which allows complete release of the midface soft tissues. A temporal incision provides access to the temporal fascia for fixation of the elevated tissues and gives the surgeon the possibility of removing redundant skin from the scalp instead of the lower eyelid. Additional posterior lamellar grafting was performed in 24 patients. There was a statistically significant reduction in the distance from the pupil centre to the lower eyelid (margin reflex distance, MRD2) 1 month after surgery (preoperative MRD2 9.62 ± 4.52 mm, postoperative MRD2 5.28 ± 2.62 mm). The ectropion and lower eyelid retraction was resolved in all patients, except for one recurrence. Midfacial elevation is a safe and effective surgical technique in the treatment of static lower eyelid malposition after chronic facial nerve palsy or posttraumatic or iatrogenic lower eyelid retraction.
