“…A deficiency in lower midface projection is common in patients with surgically corrected clefts. Both alterations in soft tissue and scarring are believed to restrict growth of maxilla and palatine after cleft repair [ 2 ]. Race is also a congenital factor associated with midface concavity, which are more common in populations of Asian and African descent [ 3 ].…”

BackgroundMidface concavity is a relatively common facial feature in East Asian populations. Paranasal augmentation is becoming an increasingly popular procedure for patients with mild concavity and normal occlusion. In this study, we evaluate clinical outcomes following a series of paranasal augmentation.MethodsA retrospective review was performed for patients with Class I occlusion who had undergone bilateral paranasal augmentation using custom-made silicone implants, between October 2005 and September 2013. Patient charts were reviewed for demographic information, concomitant operations, and postoperative complications. Preoperative and postoperative (1-month) photographs were used to evaluate operative outcome.ResultsThe review identified a total of 93 patients meeting study criteria. Overall, aesthetic outcomes were satisfactory. Five-millimeter thick silicone implant was used in 81 cases, and the mean augmentation was 4.26 mm for this thickness. Among the 93 patients, 2 patients required immediate implant removal due to discomfort. An additional 3 patients experienced implant migration without any extrusion. Nine patients complained of transient paresthesia, which had resolved by 2 weeks. There were no cases of hematoma or infection. All patients reported improvement in their lateral profile and were pleased at follow-up. Complications that arose postoperatively included 9 cases of numbness in the upper lip and 3 cases of implant migration. All cases yielded satisfactory results without persisting complications. Sensations were fully restored postoperatively after 1 to 2 weeks.ConclusionParanasal augmentation with custom-made silicone implants is a simple, safe, and inexpensive method that can readily improve the lateral profile of a patient with normal occlusion. When combined with other aesthetic procedures, paranasal augmentation can synergistically improve outcome and lead to greater patient satisfaction.

“…The primary developmental cause of midface concavity is tooth extraction, which can result in underdevelopment of the skeleton surrounding the bicuspids, which in turn causes flattening of the maxillary platform. Acquired causes consist mainly of trauma and may reflect the absence or malposition of the maxillary skeleton [ 2 ].…”

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.
