Abstract: ObjectiveTo Study effects of applying polypropylene mesh to septoplasty angioplasty. MethodsTo choose 632 surgical patients with deviation of nasal septum, among which, 448 patients were selected to use polypropylene mesh of proper size into the mucosa flap, 61 patients were treated without any filling material, and 123 patients were backfilled with nasal septum cartilages. ResultsLess patients using polypropylene mesh suffer from postoperative complications. They recover in a short period, and their nasal physiological function is properly protected. ConclusionPolypropylene mesh is one of the reliable artificial substitute materials in mucosa flap of septoplasty. It can reduce the postoperative complications as nasal septum perforation, etc. And at the same time it can protect the physiological of nasal septum and nasal cavity.

Key words: polypropylene mesh, septoplasty angioplasty, deviation of nasal septum
