Premaxillary Deficiency: Techniques in Augmentation and Reconstruction.

Progressive premaxillary retrusion is a common sequela of the facial aging process. In most cases, this manifests with central maxillary recession. Central maxillary insufficiency is also commonly encountered within certain ethnic communities, or in cleft lip nasal deformity, and may represent a challenge for the plastic and reconstructive surgeon attempting correction in the setting of facial contouring, rhinoplasty, or reconstruction following oncologic resection or trauma. Aesthetically, premaxillary retrusion may be coincident with an acute nasolabial angle and ptotic nasal tip. Minor deformities may be addressed with use of either alloplastic implants, autogenous tissue, lipotransfer, or injectable filler. Larger composite defects may require reconstruction with implementation of free tissue transfer. Herein, we describe techniques that aim to augment, or reconstruct, the premaxillary region in the context of nasal deformity, osseous resorption, or composite maxillofacial defects. © Thieme Medical Publishers.
