Dorsal hump reduction can create both functional and aesthetic problems if performed incorrectly. Component dorsal hump reduction allows a graduated approach to the correction of the nasal dorsum by emphasizing the integrity of the upper lateral cartilages when performing dorsal reduction. Use of this approach can minimize the need for spreader grafts in primary rhinoplasty patients. Possible untoward sequelae of dorsal hump reduction include long-term dorsal irregularities caused by uneven resection or overresection or underresection of the osseocartilaginous hump irregularity; the inverted-V deformity; and excessive narrowing of the midvault. The component dorsal hump reduction technique is a five-step method: (1) separation of the upper lateral cartilages from the septum, (2) incremental reduction of the septum proper, (3) dorsal bony reduction, (4) verification by palpation, and (5) final modifications (spreader grafts, suturing techniques, osteotomies). A graduated approach is described that offers control and precision at each interval. Fundamental to the final outcome is the protection and formation of strong dorsal aesthetic lines that define the appearance of the dorsum on frontal view. Furthermore, preservation of the transverse portions of the upper lateral cartilages is essential to maintain patency of the internal nasal valve, maintain the shape of the dorsal aesthetic lines, and avoid the inverted-V deformity. Finally, if needed, spreader grafts are enormously adaptable and can be customized for any deformity (unilateral or bilateral, visible or invisible) to handle functional or aesthetic problems.
