The internal nasal valve is the narrowest part of the nasal airway and its cross- sectional area is determined by the angle formed between the caudal part of the upper lateral cartilage and nasal septal cartilage The average angle of the nasal valve in a normal Caucasian ranged from 9 to 15°
Another limitation of spreader grafts is the need for long enough cartilage grafts usually harvested from the septal cartilage.
Facial Plast Surg Clin North Am Feb;12(1): Overly wide cartilaginous middle vault. Thomas JR Thomas JR, Prendiville S.Prendiville S In the setting of a wide middle vault, the reverse spreader technique is a useful alternative to dorsal augmentation, which creates the illusion of a narrower dorsum
’Neal and Berkowitz 1 in 1998 provided the first descriptive account of upper lateral cartilage flaps1 Someone uses them routinely utilized upper lateral cartilage flaps in all but the most minor (<1.5 mm) dorsal reductions
This auto-spreader is a technique in which the mucoperichondrium of the underside of the upper lateral cartilage is elevated and then released from its cartilaginous
This technique avoids harvesting and carving cartilage for grafting from other locations This technique is limited in cases of deviated dorsal septum and asymmetric dorsal aesthetic lines
Midvault reconstruction using the autospreader graft may help prevent postoperative nasal obstruction due to midvault collapse. Combining this procedure with dorsal reduction in functional rhinoplasty patients with traditional airway reconstruction techniques is effective in improving nasal airway function as measured by a patient- based, disease-specific quality-of-life instrument.
releasing the medial aspect of the upper lateral cartilage from the nasal bone, the caudal edge of the bone is exposed, allowing accurate placement of an osteotome.
