Application of Three Dimensional-Printed Polycaprolactone Nasal Mesh With the Figure of 8 Anchoring Suture Technique for Correction of Caudal Septal Subluxation

초록

Background and Objectives We evaluated the symptom improvement, surgical outcomes and post-operative complications of the figure of 8 anchoring suture technique using polycaprolactone (PCL) nasal mesh for the treatment of caudal septal subluxation. Subjects and Method We conducted a retrospective study of patients who underwent between March 2020 and March 2021 endonasal septoplasty using the figure of 8 anchoring suture technique and a PCL nasal mesh as a protective supporting graft. Fourteen patients were divided into two groups, the allergic and non-allergic rhinitis group. Symptom improvements were assessed using the Nasal Obstruction Symptoms Evaluation (NOSE) scores and visual analog scale (VAS) scores for epistaxis and headache. Post-operative patient-reported subjective changes in nasal obstruction were also recorded. All evaluations were conducted one to four months post-operatively. Results Post-operative endoscopic examination revealed that all patients had their septum straightened. The mean post-operative NOSE scores in overall and each item were significantly lower than the mean NOSE scores in the pre-operative period (p<0.05). The mean post-operative NOSE scores for patients both with and without allergic rhinitis were also significantly decreased compared to those in the pre-operative period (p<0.05). A decrease in VAS scores was significant (p=0.008) for headache but not for epistaxis (p=0.141). All patients reported improvement of subjective nasal obstruction post-operatively. Conclusion The use of figure of 8 anchoring suture technique with a PCL nasal mesh as a protective and supportive graft was proven to be a successful method for correcting caudal septal subluxation.
