Efficacy of multi-slice spiral computed tomography-based curved planar reformation combined with nasal endoscopy in the treatment of nasal bone fractures with deformities.

OBJECTIVE: To evaluate the effectiveness of multi-slice spiral computed tomography-based curved planar reformation (MSCT-CPR) combined with nasal endoscopy in treating nasal bone fractures (NBFs) with deformities. METHODS: This study included 100 NBF patients with deformities admitted to Second Hospital of Hebei Medical University from June 2022 to June 2024. The control group (n=43) underwent conventional surgery, while the experimental group (n=57) received MSCT-CPR-guided nasal endoscopy. Pre- and post-treatment nasal morphology changes were evaluated. Therapeutic outcomes, nasal appearance, ventilation function, olfactory dysfunction, and nasal cavity parameters (minimum cross-sectional area, nasal cavity volume, and total nasal exhaled volume) were assessed. Postoperative complications (nasal airflow obstruction, intranasal adhesions, cosmetic changes, and postoperative infections) were also documented. Univariate and multivariate analyses (binary logistic regression) were performed to identify potential efficacy determinants. RESULTS: The experimental group achieved a significantly higher total effective rate (P=0.010) than the control group, along with superior improvements in nasal appearance, ventilation function, and olfactory performance (all P<0.05). Additionally, the experimental group demonstrated more pronounced enhancements in nasal cavity parameters (all P<0.05), with a lower overall postoperative complication rate (P=0.026). Univariate analysis identified associations between treatment efficacy and variables like patient age, body mass index, fracture type, trauma mechanism, smoking history, and septal involvement (all P<0.05); however, these associations did not persist in the multivariate analysis (all P>0.05). CONCLUSION: MSCT-CPR plus nasal endoscopy significantly improves treatment outcomes, enhances nasal function and aesthetic restoration, optimizes nasal cavity morphology, and minimizes postoperative complications in NBFs with deformities.
