Limited septoplasty as treatment for recurrent epistaxis in a child with Glanzmann's thrombasthenia.

Recurrent epistaxis can be a serious problem in children with coagulation disorders. We present a case of severe, recurrent nosebleeds in a 3-year-10-month-old boy with Glanzmann's thrombasthenia. The nature of Glanzmann's disease and medical treatment of epistaxis in children is reviewed. A method of controlling recurrent epistaxis with a very simple and limited septoplasty is described. This technique should be applicable to patients with recurrent nosebleeds and other more common coagulation disorders.

Temporoparietal fascial flap in orbital reconstruction.

OBJECTIVE: 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. DESIGN: Retrospective analysis. SETTING: Tertiary medical center. PATIENTS: Nine patients with diverse orbital cavity or periorbital soft tissue and bony defects due to trauma, benign or malignant neoplasms, and radiation treatment. INTERVENTIONS: 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. MAIN OUTCOME MEASURES: Functional and aesthetic outcomes were determined by physical examination and preoperative and postoperative photographs. RESULTS: 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. CONCLUSIONS: 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.

Hair-bearing temporoparietal fascial flap reconstruction of upper lip and scalp defects.

BACKGROUND: The temporoparietal fascial flap has proven to be a versatile flap for a broad spectrum of reconstructive problems in the head and neck. The temporoparietal fascial flap is a thin, pliable layer of richly vascularized tissue that may be transferred either pedicled or free and alone or as a carrier of subjacent bone or overlying skin and scalp. OBJECTIVE: To report our experience using a hair-bearing temporoparietal fascial flap for reconstruction in 6 male patients with extensive upper lip and scalp defects, including a discussion of the surgical anatomy and technique. METHODS: Temporoparietal fascial flaps with overlying scalp were used as pedicled and free flaps for the reconstruction of upper lip and scalp defects. RESULTS: All reconstructive results were satisfactory. Oral competence, measured by both speech and mastication performance, was achieved in patients with upper lip defects. Healthy scalp coverage was obtained in patients with local defects. The cosmetic appearance was satisfactory to all patients. CONCLUSIONS: Ideal reconstruction of large upper lip and scalp defects is achieved with local tissue that best mimics the normal face color, texture, and hair-bearing qualities. Hair-bearing temporoparietal fascial flaps possess these characteristics and are an excellent choice for the restoration of function and aesthetics.

Familial incidence of labial pits.

Congenital pits of the lower lip are rare malformations, inherited in an autosomal dominant fashion (penetrance approximately 80 per cent), and closely associated with cleft lip, cleft lip/palate, or isolated cleft palate. The phenomenon of paramedian labial pits is discussed, and an example of inheritance pattern is reported.
