Recession of the premaxillary area is a relatively common deformity. Typically, it presents as a mild weakness of the central maxilla, but in certain instances, such as in the Black and Asian communities, it may be moderate to severe. This condition can be compounded by a narrow nasolabial angle, recessed alar bases, and sunken cheeks. To resolve this deficiency, a new design for premaxillary augmentation is suggested. A bat-shaped premaxillary implant is used for correction. The implant is introduced by means of an intranasal or intraoral approach, while the patient is under either local or general anesthesia. Thirty-three patients have been managed for premaxillary recession and have been corrected by premaxillary augmentation. Satisfactory cosmetic results have been achieved, with only a few minor complications.
前上颌区域后缩是一种相对常见的畸形。通常,它表现为上颌中部轻度薄弱,但在某些情况下,如在黑人和亚洲人群中,可能为中度至重度。这种情况可能因鼻唇角狭窄、鼻翼基部后缩和脸颊凹陷而加重。为解决这一缺陷,提出了一种新的前上颌隆突设计。使用蝙蝠形前上颌植入物进行矫正。在局部或全身麻醉下,通过鼻内或口内途径植入植入物。33例患者接受了前上颌后缩治疗,并通过前上颌隆突矫正。取得了满意的美容效果,仅出现了一些轻微并发症。
