title: Anchoring temporalis muscle to porous polyethylene sheet fixed at the temporal crest in the temporal depression.
abstract: We devised a new technique of anchoring temporalis muscle to a porous polyethylene sheet (Medpor) fixed at the temporal crest in the temporal depression. A coronal incision was made, and subgaleal dissection was continued to the undersurface of the superficial temporal fascia. Contracted temporalis muscle was freed from the temporal bone along its inner surface until 2 cm above the zygomatic arch. To mobilize the muscle effectively, transverse scoring was performed on the undersurface of the contracted temporalis muscle. After the temporal crest was exposed, a porous polyethylene sheet (Medpor) of 10 cm curvilinear and of 1-cm width was fixed on the temporal crest with 3 titanium screws. Several absorbable sutures were passed through the temporalis muscle, anchored to the polyethylene sheet, and tightened. Three patients with temporal depressions were operated on by this method with satisfactory results. We think that this method might be of use in resuspension of the contracted temporalis muscle, especially in secondary depression of the temporal area due to neurosurgical procedures.
