Local flap reconstruction of large scalp defects.

Scalp defects can have a number of origins, and their repair is dependent upon their location, size and depth. In the case of the scalp, the repair of even small defects is complicated. Local flaps are the reference for the reconstruction of such defects. Knowledge of scalp anatomy is essential for preparing these flaps, which must be based on one or two vascular pedicles to afford a large rotation angle--thereby facilitating closure of the defect. The parietal zone is the location offering the greatest flap mobilization possibilities. We present a case involving the repair of a major pericranial frontoparietal scalp defect. A local transverse posterior transpositioning scalp flap was raised with the posterior auricular and occipital arteries as vascular pedicle. Following repositioning of the flap, a free partial-thickness skin graft from the thigh was used to cover the donor zone. A review is provided of the different techniques for the reconstruction of large scalp defects.

Gingival neurofibroma in a neurofibromatosis type 1 patient.

Neurofibroma is a benign peripheral nerve sheath tumour. It is one of the most frequent tumours of neural origin and its presence is one of the clinical criteria for the diagnosis of type 1 neurofibromatosis (NF-I). Neurofibromatosis type 1 is an autosomal dominantly inherited disease due to an alteration in the long arm of chromosome 17. About 50% of NF-I patients have no family history of the disease. NF-I patients have skin lesions (cafe au lait spots and neurofibromas) as well as bone malformations and central nervous system tumours. Diagnosis is based on a series of clinical criteria. Gingival neurofibroma in NF-I is uncommon. Treatment of neurofibromas is surgical resection. The aim of this paper is to report a case of NF-I with gingival involvement and to review the literature.

Gingival neurofibroma in a neurofibromatosis type 1 patient. Case report

El neurofibroma es un tumor benigno, de los nervios periféricos, desarrollado a partir de la vaina neural. Representa uno de los tumores de origen neurógeno más frecuente y es uno de los criterios clínicos de diagnóstico de neurofibromatosis tipo 1 (NF-I). La NF-I es una enfermedad genética producida por una alteración en el brazo largo del cromosoma 17. La mitad de los casos tienen antecedentes familiares y el 50% son mutaciones nuevas. Los pacientes con NF-I principalmente presentan lesiones en la piel (manchas “café con leche” y neurofibromas), así como malformaciones óseas y tumores del sistema nervioso central. El diagnóstico de la enfermedad se basa en una serie de criterios clínicos. La aparición de neurofibromas en la encía en pacientes con NF-I es poco común El tratamiento de los neurofibromas es la escisión quirúrgica. El objetivo de este artículo es presentar un caso de NF-I con afectación neurofibromatosa de la encía maxilar, diagnosticado y tratado quirúrgicamente en nuestro Servicio de Cirugía Oral y Maxilofacial y realizar una revisión de la literatura
