Abstract

The internal nasal valve (INV) refers to the slit-like region between the caudal end of the upper lateral cartilage (ULC) and the nasal septum. It is the narrowest portion and primary regulator of the nasal airway. Reduction rhinoplasty decreases the nasal airway cross-sectional area and may cause symptoms, unless additional surgical measures are taken. Rhinoplasty or septorhinoplasty was performed for 76 patients with a nasal hump, using an external approach. As a consequence of the nasal hump removal, the ULCs were separated from the septal cartilage. All patients underwent one of the three forms of cartilaginous nasal dorsum reconstruction: primary closure (PC) (50 patients); spreader graft (SG) (19 patients); or upper lateral splay graft (ULSG) (7 patients). At least 3 months postoperatively. INV obstruction was evaluated by asking the patients about nasal obstruction symptoms and visually examining the INV with an otoscope. Nasal obstruction complaints and INV constriction found among patients in the PC. SG and ULSG groups were 16 (32%), 2 (10.5%) and none, respectively. The results of the PC group were compared statistically with the combined results of the SG and the ULSG groups. The patients in the combined SG-ULSG group had significantly less nasal obstruction complaints and INV angle constriction compared with the PC group. Due to the higher rate of postoperative INV stenosis. PC should be avoided. The author uses ULSG when the septal cartilage appears straight and sturdy and SGs when the straightened septal cartilage looks weak and vulnerable, since SGs not only improve the INV, but also reinforce the septal cartilage.
