Swing Door Compressive Fracture Technique for Turbinoplasty: Retrospective Study Based on Computed Tomography and...

Treatment of inferior turbinate hypertrophy is performed using different techniques in rhinoplasty. However, the reported results are not consistent. In this study, we aimed to evaluate the outcomes of Swing door compressive fracture (SDCF) technique for turbinoplasty using computed tomography (CT) and Nasal Obstruction Symptom Evaluation (NOSE) scale.

This study involved retrospective analysis of 24 patients who underwent inferior turbinoplasty using Swing door compressive fracture (SDCF) technique with or without septoplasty. The angle between the inferior turbinate and lateral nasal wall, total area, inferior turbinate area and the area medial to inferior turbinate were measured preoperatively and postoperatively using coronal section CT images for objective evaluation. Moreover, the NOSE scale was used for subjective evaluation.

The angle between inferior turbinate and lateral nasal wall was decreased by 25.3% after the treatment (p <0.0001). Inevitably, postoperative total nasal airway area (area 1) did not face a statistically significant change (p = 0.6878). On the other hand, the area of inferior turbinate (area 2) decreased significantly compared to preoperative value (p = 0.0021), while the area 3, the area medial to inferior turbinate was widened 1.5 times postoperatively. The total preoperative NOSE score was moderate (39.58 ± 22.31%) and it was decreased to mild (5.83 ± 8.81%) after the treatment (p <0.0001).

The Swing door compressive fracture (SDCF) technique for turbinoplasty is an effective and straightforward modality. However, the further study involving more patients and longer follow-up period is mandatory.
