Supramuscular upper blepharoplasty approach to orbital roof and/or lower anterior table frontal sinus fractures: A meta-narrative review.

[BACKGROUND] An approach to orbital roof fractures (ORFs) and/or lower anterior table frontal sinus fractures (LATFSFs) is a challenging task. The conventional coronal approach (CCA) appears to suit multiple/complex fractures of the upper face, while periorbital transcutaneous incisions (PTIs), e.g. gull wing, open sky, butterfly, and Lynch incisions, often impair aesthetic outcomes. The aims of this paper were to provide an overview of the supramuscular upper blepharoplasty approach (SUBA) to ORFs/LATFSFs.

[METHODS] Using a meta-narrative review study design, the investigators enrolled published data extracted from PubMed/Medline, Embase, Cochrane Library, and Google Scholar concerning SUBA to ORFs/LATFSFs. Only publications with the highest and most recent level of evidence (LoE) in English, French or German available until 6 May 2022 were included. The LoE were evaluated using the 2011 Oxford Centre for Evidence-Based Medicine (OCEBM)'s classification.

[RESULTS] In total, 70 articles were included; however, most contained low LoE. Under general and local anaesthesia, SUBA to ORFs/LATFSFs can be performed safely and appeared to be superior to its submuscular counterpart in terms of fewer risks of adjacent tissue injuries, and speedy operative time (maximal 5 min. in experienced hands).

[CONCLUSIONS] In contrast to CCA and PTIs, the SUBA is a minimally invasive approach to the ORF/LATFSF with favourable aesthetic outcomes, direct visualisation of the fracture, quick operative time, rare complications, and easy learning.
