Risk Factors for Postoperative Inflammatory Complications After Maxillofacial Reconstruction Using...

Area of Science:

• Biomaterials Science
• Craniofacial Surgery
• Medical Device Research

Background:

• Polyether-ether-ketone (PEEK) implants are increasingly utilized for craniomaxillofacial reconstruction.
• Limited data exist on the risk factors and limitations associated with PEEK implant use in this context.

Purpose of the Study:

• To identify risk factors for postoperative inflammatory complications (POICs) following craniomaxillofacial reconstruction using PEEK implants.
• To inform preoperative evaluations and surgical planning to mitigate potential risks.

Main Methods:

• Retrospective cohort study of patients treated with patient-specific PEEK implants between August 2012 and June 2019.
• Analysis of demographic, medical, anatomic, and treatment-related variables.
• Statistical analysis including Fisher exact tests, t tests, and multivariable logistic regression.

Main Results:

• The study included 32 patients; 28.1% experienced POICs.
• Risk factors associated with POICs included tobacco use, intraoral incisions, and multiple incisions.
• Multivariable analysis indicated a statistically significant association between multiple incisions and POICs.

Conclusions:

• Tobacco use and the planned use of multiple incisions are potential risk factors for POICs after PEEK implant reconstruction.
• Preoperative assessment should carefully consider smoking status and the necessity of multiple incisions.
• Further research may elucidate the precise mechanisms and optimal management strategies for PEEK-related complications.
