Management of the middle nasal vault in rhinoplasty

Abstract

The incidence of aesthetic and functional complications of rhinoplasty can be decreased by preserving supportstructures of the nose. This is particularly important in patients at high risk for collapse of the middle nasal vault (cartilaginous nasal vault). Aggressive surgical manipulation of the upper lateral cartilages can result in excessive narrowing of the middle vault and collapse of the internal nasal valve. Spreader grafts can be used to provide appropriate width to the middle vault and preserve nasal valve function. This paper will discuss indications and technique for application of spreader grafts using the open rhinoplasty approach. Spreader grafts can be used in high risk patients with short nasal bones, long weak upper lateral cartilages, thin skin, and narrow projecting nasal vault. These patients are at higher risk for excessive narrowing of the middle vault (inferomedial collapse of upper lateral cartilages) because of loss of medial support after hump removal. Spreader grafts will support the lateral nasal wall, preserve nasal width, and prevent deformity. Spreader grafts can also be used to add width to the cartilaginous vault in disproportioned noses that have an excessively narrow middle vault and broad nasal tip. This maneuver will allow the surgeon to perform conservative narrowing of the nasal tip and prevent deformity or compromise of nasal function. Spreader grafts can be used in combination with lateral crural grafts or alar batten grafts to correct secondary deformities of the internal and/or external nasal valve. Conservative reduction and thoughtful augmentation in rhinoplasty will preserve nasal support and function with improved long-term results.
