Microvascular Reconstruction of Complex Nasal Defects: Case Reports and Review of the Literature.

ABSTRACT

The area of nasal reconstruction can be challenging for the microsurgeon, as the nose is a complex structure. A 3-dimensional understanding of the organ is a prerequisite for a successful outcome. A combination of procedures is usually necessary to completely repair subtotal or total nasal defects. Contouring and secondary revisions may ensue to enhance the postoperative functional and aesthetic outcome of the reconstruction. This study aimed to present a review of the various methods of microvascular reconstruction for complex nasal defects based on the radial forearm flap (RFF). METHODS: Two independent reviewers screened the literature on PubMed according to the inclusion criteria. The keywords for the search were "microvascular," "nasal reconstruction," and "free flaps in nasal reconstruction." Articles on locoregional flap reconstruction, experimental animal studies, letters to the editors, non-English literature, and articles without full text were excluded from the study. The protocol is registered at the International Prospective Register of Systematic Reviews (CRD42019146447) under the umbrella of the National Institute for Health Research, and it is reported in line with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses statement. RESULTS: Eighteen eligible studies were included in our articles. The infolding RFF, multiple skin paddles RFF, and prelaminated RFF were described. The results have been more than encouraging so far. Also, 3 clinical cases where the RFF provided intranasal lining and a forehead flap resurfaced the nose were presented. CONCLUSION: The RFF is a reliable technique for nasal reconstruction in expert hands.
