Objective To explore the effect of deviated nasal septum correction combined with nasal tip plasty on nasal morphology improvement in patients with deviated nasal septum. Methods A total of 62 patients with deviated nasal septum admitted to the Department of Otolaryngology-Head and Neck Surgery, Affiliated Hospital of Nantong University from March 2022 to March 2025 were selected, and they were divided into the control group and the observation group by the random number table method, with 31 patients in each group. The control group received endoscopic deviated nasal septum correction with two-line tension reduction technique, and the observation group received deviated nasal septum correction combined with nasal tip plasty. The clinical efficacy, nasal morphology improvement, quality of life and satisfaction with nasal plasty were compared between the two groups. Results There was no statistically significant difference in the total effective rate between the two groups (P >0.05). The differences in nasal bridge deviation angle, nasal tip projection and nasofrontal angle of the observation group were higher than those of the control group (P <0.05). The scores of ROE in the observation group at 3 months and 6 months after surgery were higher than those in the controlgroup (P <0.05). The satisfaction with nasal plasty of the observation group was higher than that of the control group (P <0.05). Conclusion Deviated nasal septum correction combined with nasal tip plasty has a good effect. It can improve nasal appearance and function, and enhance postoperative satisfaction and quality of life.
