Storia della chirurgia della valvola nasale

Nasal valve surgery involves the Nasal Valve Area and its deformities, as well as its surrounding structures. Since there is no single technique to solve every type of pathology, there are numerous works on this topic in the literature. The rhinologist to perform such surgery should thoroughly deal with all the components (i.e. nasal valve area, nasal bones, tip, spine, vestibulum and turbinates). However, even more so, he should be able to precisely locate the cartilaginous and/or osseous structural deformity impairing nasal air flow. Therefore, intuition and experience play a key role in planning such surgery. It is not easy to recognize the unique, or even more difficult, the partial defect the correction of which would improve overall nasal function. Every surgical technique has some "biologic cost": sclerosis, adhesions, and scar retraction. However, in this case the surgery could prove even more biologically costly as it could worsen the already poor nasal breathing. Therefore, the surgeon must strictly follow two basic rules: a) employ a proper approach to the region; b) do not endanger nasal valve function to satisfy esthetics. Valve area anomalies can be divided into primary and secondary. The latter are caused by trauma or surgery (1.2%). Among the wide range of techniques mentioned in the literature, the authors prefer the anatomical, surgical classification by Zijilker and Quaedvilieg as it incorporates the philosophy the rhinosurgeon must keep in mind when aiming to restore both nasal functions and esthetics through different, specific techniques.
