Use of Distraction Osteogenesis in Arrhinia

Nasal malformations such as hemiarrhinia and arrhinia have a very low incidence, although many treatment protocols have been described. In this article, we describe 2 surgical techniques to treat arrhinia depending on the age at the beginning of treatment. In our practice, we use Le Fort III osteotomy with distraction osteogenesis as a pillar of the reconstruction because it allows to improve anteroposterior and vertical projections of the midface, giving a proper platform for nasal reconstruction, decreasing the number of interventions. We report a patient with a hemiarrhinia who has completed appropriate reconstruction results and a patient with total arrhinia in whom the distraction was achieved to create a nasal bone support and improve midface projection.

Hypertelorism and Micro-Orbit Simultaneous Correction in a Patient With Paramedian Bilateral Facial Clefts

The aim of this article is to describe the results of the use of demineralized bone matrix putty in alveolar cleft of patients with cleft lip and palate. We performed a prospective, descriptive case series study, in which we evaluated the results of the management of alveolar clefts with demineralized bone matrix. Surgery was performed in 10 patients aged between 7 and 26 years (mean 13 years), involving a total of 13 clefts in the 10 patients. A preoperative cone beam computed tomography (CBCT) was taken to the patients in whom the width of the cleft was measured from each edge of the cleft reporting values between 5.76 and 16.93 mm(average, 11.18 mm). The densities of the clefts weremeasured with a CBCT, 6 months postoperative to assess bone formation. The results showed a register of gray values of 1,148 to 1,396 (mean, 1,270). The follow-up was conducted for 15 to 33 months (mean, 28.2 months). The results did not show satisfactory bone formation in the cleft of patients with the use of demineralized bone matrix.

El problema PIP, origen y consecuencias

El uso de materiales no certificados para la fabricación de las prótesis Poly Implants Prothèse (PIP) ha generado una alerta a nivel mundial, en la cual los diferentes medios de comunicación han jugado un papel trascendental difundiendo diferentes teorías y mitos sobre las posibles consecuencias por el uso de estas. El creciente número de publicaciones científicas sobre los desenlaces en pacientes con implantes PIP fraudulentos ha permitido unificar conceptos y esclarecer las consecuencias de su utilización. Esta es una revisión de la literatura en la que se presentan las características químicas de los materiales manejados para la fabricación de las prótesis PIP, las complicaciones que se han descrito y las diferentes políticas gubernamentales que se han tomado para hacer frente a esta alerta sanitaria mundial.

Hypertelorism and Micro-Orbit Simultaneous Correction in a Patient With Paramedian Bilateral Facial Clefts

The aim of this paper is to report a case of a patient with paramedian bilateral facial clefts and hypertelorism associated with a severe encephalocele and micro-orbit. The patient required a facial bipartition to correct a transsphenoidal encephalocele, and a modified medialization surgery of the orbits to simultaneously expand the micro-orbit and correct the hypertelorism. These procedures achieved hypertelorbitism correction, orbital expansion which allowed symmetrical facial growth, and a functional orbit that permitted the use of an ocular prosthesis. We present this unique case to highlight the predictable results of a procedure that combines 2 surgical reproducible techniques of craniofacial surgery
