Abstract

The nasal midvault is an important consideration in rhinoplasty. This region is defined by the attachment of the upper lateral cartilages (ULCs) to the nasal bones superiorly and the cartilaginous septum medially. Inadequate management of the nasal midvault can have negative functional and aesthetic ramifications. Indications for midvault reconstruction in primary rhinoplasty include a narrow midvault, dorsal hump resection, a deviated midvault, and an asymmetric midvault, with an additional relative indication of zone 1 lateral wall insufficiency (LWI), defined as dynamic collapse of a weakened lateral nasal wall at the level of the ULC. Numerous techniques for midvault reconstruction have been described, dating back to Sheen's description of the spreader graft in the 1980s, which remains the gold standard for repair. Herein, the various indications for midvault reconstruction are described, along with a discussion of the most commonly used techniques for successful reconstruction.
