| pubmed-article:6486318 | pubmed:abstractText | Head and neck deformities of congenital, traumatic, or neoplastic cause often require reconstruction. At the University of Virginia over the past 14 years, we have used galeal, temporalis fascial, and pericranial flaps to correct these defects in more than 150 patients. Dissection of these flaps on both cadavers and reconstructive patients had demonstrated new anatomic findings different from those reported in standard textbooks. The galea is the most superficial layer of fascia. The pericranium is the next tissue layer. It is continuous above and separate from the temporalis muscle fascia. We may, therefore, consider three separate fascial layers for reconstruction. A rich vascular plexus arises from branches of the external and internal carotid arteries. Blood flow is axial to the galea and temporalis fascia. Pericranium has a dual supply from peripheral axial vessels and from perforating vessels from the overlying galea. Galeal, temporalis fascial, and pericranial flaps are reliable, thin, and supple and have a good arc of rotation and minimal donor site morbidity. They may be used to cover bone, cartilage, or implants, may be folded for bulk, may be used to carry blood to poorly vascularized recipient sites, or may be used to nourish bone, cartilage, skin, and mucosal grafts. Their versatility permits a wide variety of potential applications in head and neck surgery. | lld:pubmed |
