High-density polyethylene material versus autogenous grafts in craniofacial augmentation procedures

Abstract

Aim: The objective was to do a comparative study and to evaluate the outcome in overall acceptance for correction of residual facial deformity with autogenous graft versus porous polyethylene implants. Materials and Methods: A total of 16 patients in the age group of ≥15 years irrespective of sex, caste, religion, and socioeconomic status presenting with signs and symptoms of residual facial deformities and who were declared fit for surgery were included in the study. The study patients were further divided into two groups, of eight each. Deformity correction using autogenous grafts was performed in Group A and using high-density polyethylene (HDPE) alloplastic implants was performed in Group B. During the follow-up period, patients’ and doctor rating of overall acceptance between autogenous and alloplastic (HDPE) bone grafts was recorded on 100-mm visual analog scale (VAS) on the 2 nd day and 7 th day and at 3, 6, and 12 weeks. Results: The unpaired t -test is used for evaluation. VAS score at all the follow-up periods above stated was significantly higher in alloplastic group than in the autogenous group for both in patients and doctor evaluation. Conclusion: From the present study, it can be concluded that porous HDPE implants are an effective alternative to autogenous grafts in accordance of overall acceptance for correction of residual facial deformity when proper case selection, exclusion of negative prognostic factors, and meticulous surgical procedure are followed.
