Use Of Temporoparietal Fascial Flap Research Articles

Renewed Concept of Mastoid Cavity Obliteration with the Use of Temporoparietal Fascial Flap Injected by Injectable Platelet-Rich Fibrin after Subtotal Petrosectomy for Cochlear Implant Patients.

Background: The subtotal petrosectomy procedure may be useful for cochlear implantation in selected patient groups. Although it is highly effective, complications can arise, which may have economic implications for the patient due to the high cost of the device. Therefore, several authors have attempted to identify the most effective concept for obliteration. Methods: We present a pilot descriptive study of application techniques for obliterating cavities after subtotal petrosectomy using a temporoparietal fascial flap (TPFF) modified with injectable platelet-rich fibrin (IPRF+) for three cochlear implant (CI) patients. Results: Our concept preserves important anatomical structures, such as the temporalis muscle, which covers the CI receiver-stimulator. Injection of IPRF+ also increases the available tissue volume for obliteration and enhances its anti-inflammatory and regenerative potential. Conclusions: To the best of our knowledge, the use of TPFF for filling the cavity has not been adopted for CI with SP and for blind sac closure. Our literature review and our experience with this small group of patients suggest that this procedure, when combined with IPRF+ injections, may reduce the risk of potential infection in the obliterated cavity, particularly when used with CI. This technique is applicable only in cases when the surgeons are convinced that the middle ear cavity is purged of cholesteatoma.

Salvage of Extensive Skin Graft Necrosis After Auricle Reconstruction by Using Modified Nagata Method.

Extensive skin graft necrosis after auricle reconstruction surgery is a thorny problem for plastic surgeons. Four unilateral microtia patients were enrolled for extensive skin graft necrosis after ear elevation surgery. Early debridement and daily dressing changes were important for preoperative preparation. Surgical treatments involved local flaps and secondary split-thickness skin graft. After 3 to 12 months of follow-up, clear surface structures and obvious auricular sulcus were shown in all 4 patients. No cartilage exposure, skin necrosis, healing impairment, or other complications were found. We attribute the cause of extensive skin graft necrosis to subcutaneous hematoma. Local skin flaps and split-thickness skin grafting can be effective treatments for such situations. The use of temporoparietal fascial flap is unnecessary when poor graft survival is caused by subcutaneous hematoma.

The Versatile Use of Temporoparietal Fascial Flap

The pedicled or free temporoparietal fascial has been used in many areas, especially in head and neck reconstruction. This thin, pliable, highly vascularized flap may be also transferred as a carrier of subjacent bone or overlying skin. The aim of this study is to report our experience in versatile use of temporoparietal fascial flap (TPFF) and discuss the surgical anatomy and technique. A total number of 57 TPFFs have been used in periorbital, mid-facial, auricular, and tracheal reconstruction due to tumor resection, trauma, and congenital ear deformities. All the flaps were successfully transferred without any major complication. The cosmetic results were quite satisfactory to all patients. The advantages and minimal donor site morbidity of TPPF makes this flap a good choice in many reconstructive procedures.

Temporoparietal Fascial Flap in Orbital Reconstruction

To evaluate the success of the temporoparietal fascial flap (TPFF) in the primary or secondary reconstruction of difficult orbital defects and to review the surgical techniques. Retrospective analysis. Tertiary medical center. Nine patients with diverse orbital cavity or periorbital soft tissue and bony defects due to trauma, benign or malignant neoplasms, and radiation treatment. Temporoparietal fascial flap anatomy and techniques of harvest and inset are reviewed in detail. Four cases are presented to illustrate possible variables in orbital reconstruction. Variables examined include the location of defects, the success of flap survival in orbital cavities after primary or secondary reconstruction, the effects of prior irradiation on flap survival, and the possibility of concurrent osteointegrated implant placement with TPFF reconstruction. Functional and aesthetic outcomes were determined by physical examination and preoperative and postoperative photographs. All patients had successful transfer of TPFF grafts without flap compromise. Temporoparietal fascial flap was a viable option for subtle orbital and malar contour defects. In chronically inflamed wounds such as with osteoradionecrosis and orbitoantral fistula, TPFF successfully restored vascularity, obliterated the defects, and enabled the placement of osteointegrated implants. The TPFF also supported the concurrent placement of a free calvarial bone graft. Finally, split-thickness skin grafted onto a pedicled TPFF showed 100% survival. The TPFF is one of the most reliable and versatile regional flaps in the head and neck for orbital reconstruction. This study presents the use of TPFF in a variety of orbital defects, from lateral bony rim defects to total exenteration. Timing of repair in this study spans from immediate reconstruction to reconstruction delayed more than 50 years after the initial injury. In all cases, reconstruction with TPFF resulted in improved bony and soft tissue contours, and incurred minimal morbidity.
