[The clinic research of septoplasty according to different types of nasal septal deviation].

Objective:To divide the deviation parts of nasal septal into different deviation units，and then classify them according to the the deviation units through nasal endoscope, and carry out individual septoplasty for the deviation types. Method:One hundred and twenty patients having operation indication with different types of nasal septal deviation according to the standard designed by the researchers were included. All included patients underwent individual septoplasty. Result:All included patients， symptoms of nasal obstruction had different degree of improvements after the individual surgery according to the different types of nasal septal deviation. Conclusion: Using the classification of nasal septal deviation based on the deviation units, physicians can implement individual septoplasty for patients, which has great guidance to clinical practice. The study has got great results in practice, and deserved extending.
