OBJECTIVES/HYPOTHESIS: To evaluate the safety, efficacy, and result stability of polydioxanone (PDS) plate use for L-strut stabilization.
Retrospective analysis of a prospective cohort.
Patients who underwent functional septorhinoplasty with the use of PDS plates between January 2013 and January 2017 were administered the Nasal Obstruction Symptom Evaluation (NOSE) scale pre- and postoperatively at 2, 4, 6, and 12 months. Patient demographics, reason for PDS use, graft type, complications, and outcomes were analyzed.
Eighty-eight patients aged 34.3 years (standard deviation [SD] = 15.7 years; range, 7.5-71.5 years) were included. All patients were found to have a fracture and/or severe deviation of the L-strut for which the PDS plate was used for rigid support. Mean preoperative NOSE score 65.2 (SD = 22.1) significantly decreased to 19.6 (SD = 21.6) at 7.2 months (SD = 5.5 months) postoperatively. There were no significant differences in NOSE scores between follow-up time points. There was one complication, a septal abscess, and one revision.
A PDS plate is a safe and effective material to be utilized in functional septorhinoplasty for patients with a fracture or iatrogenic injury to the septal L-strut or poor quality septal cartilage that requires stability without additional width. Outcomes are stable at 6 and 12 months, after the plate has dissolved. The use of a PDS plate may decrease the need for rib grafting in patients with a history of previous septoplasty and persistent nasal obstruction with a dorsal or caudal C-shaped septal deformity or fracture of the L-strut.

目的/假设：评估聚二氧六环酮（PDS）板用于L形支柱稳定的安全性、有效性和结果稳定性。
对前瞻性队列进行回顾性分析。
对2013年1月至2017年1月期间使用PDS板进行功能性鼻中隔成形术的患者，在术后2、4、6和12个月进行术前和术后鼻阻塞症状评估（NOSE）量表评分。分析患者人口统计学资料、使用PDS的原因、移植物类型、并发症及结果。
纳入88例年龄34.3岁（标准差[SD]=15.7岁；范围7.5 - 71.5岁）的患者。所有患者均有L形支柱骨折和/或严重偏曲，使用PDS板进行坚固支撑。术前平均NOSE评分为65.2（SD = 22.1），术后7.2个月（SD = 5.5个月）显著降至19.6（SD = 21.6）。随访时间点之间的NOSE评分无显著差异。发生1例并发症，为鼻中隔脓肿，1例翻修手术。
对于鼻中隔L形支柱骨折或医源性损伤，或鼻中隔软骨质量差且需要稳定性而无需增加宽度的患者，PDS板是功能性鼻中隔成形术中一种安全有效的材料。在钢板溶解后的6个月和12个月时结果稳定。对于既往有鼻中隔成形术史且持续鼻阻塞、伴有背侧或尾侧C形鼻中隔畸形或L形支柱骨折的患者，使用PDS板可能减少肋骨移植的需求。
