Abstract:Objective To study and analyze the clinical efficacy of multislice spiral computed tomography (MSCT) combined with nasal endoscopy in treatment of nasal bone fracture with malformation.Methods 87 patients with nasal bone fracture combined with malformation from January 2019 to January 2021 were included in the study and divided into a combined group of 43 patients and a control group of 44 patients according to the random number table method. The control group was treated with conventional surgery, while the combined group was treated with MSCT surface reconstruction combined with nasal endoscopy. The clinical efficacy, nasal appearance, nasal ventilation function and olfaction disorder score before and after surgery, minimum nasal cross-sectional area, nasal volume before and after surgery, and postoperative complications were analyzed.Results The overall effective rate of the combined group was higher than that of the control group, the difference was statistically significant (P < 0.05). Postoperative nasal appearance and olfactory disorder scores in combination group were lower than those in control group, while total nasal expiratory volume was higher than that in control group, the difference were statistically significant (all P < 0.05). The minimum nasal cross-sectional area and nasal volume of the combined group were larger than those of the control group, the difference were statistically significant (all P < 0.05). The total incidence of postoperative complications in the combined group was lower than that in the control group (P < 0.05).Conclusion MSCT combined with nasal endoscopy in the treatment of nasal bone fracture with malformation has a significant clinical effect, can significantly improve the nasal ventilation function of patients, and is beneficial to reduce the risk of postoperative complications. It is worthy of clinical application.
