Surgical Management of the Internal Nasal Valve: A Review of Surgical Approaches.

[BACKGROUND] Nasal valve collapse is relatively common with a lifetime prevalence of up to 13%. Etiologies include prior rhinoplasty, other surgical procedures, facial paralysis, congenital defects, trauma, and aging. Internal nasal valve collapse leads to impairment of nasal breathing, which significantly disturbs quality of life. Many approaches to increase the cross-sectional area of the internal nasal valve have been described.

[RESULTS] The main categories reviewed in this article are cartilage grafting, implants, and suture suspension techniques. Cartilage grafting techniques include alar batten graft, butterfly graft, spreader graft, autospreader graft, and alar composite graft. The implant technique includes the titanium butterfly implant. The suspension techniques included are the transconjunctival approach, Mitek bone anchor, flaring suture, lateral pull-up, and piriform rim suspension. Surgeons must carefully consider functionality, cosmesis, and technical difficulty when selecting an approach.

[DISCUSSION] We review indications, general approach, benefits, and considerations for a number of available techniques to help surgeons decide what approach might be best suited to the individual patient.
