Purpose:
The aim of the present study was to perform a comparative analysis of the utility, outcomes, and complications of DCIA (deep circumflex iliac artery) flap for the reconstruction of maxillofacial defects between two institutions that continue to use the DCIA flap as a reconstructive resource.
Materials And Methods:
This retrospective analysis included a total of 68 patients (mean age 51.1 years) at the University Hospital of Parma, Parma, Italy, and the University of Maryland, Baltimore, USA, between January 2010 and April 2019.
Results:
No statistical differences were found in relation to the site of reconstruction (p = 0.09), bone graft quantity (p = 0.93), rehabilitation with dental implants (p = 0.464), length of hospitalization (p = 0.086), BMI (0.677), swallow function (p = 0.419), medical comorbidities (p = 0.933), pre-existing radiation (p = 0.691), adjuvant treatment (p = 0.298), ECOG-PS pre-and post-surgery (p = 0.329; p = 0.545), and flap failure: one partial failure observed (p = 0.412) and donor site morbidities (p = 0.742). A noted trend to increased risk of hernia without the use of a primary mesh repair was observed (p = 0.059).
Conclusion:
The DCIA free flap represents a useful and reliable reconstructive flap for maxillofacial reconstruction. Reconstructive microvascular surgeons should be proficiently trained in this flap technique for its consideration as a first-line option in maxillofacial reconstruction.
