Modified cheek advancement flap for medial lower eyelid, nasal sidewall and infraorbital cheek reconstruction: a case series.

Aim: To describe and evaluate surgical outcomes of the Modified Cheek Advancement Flap (MCAF) to reconstruct defects involving medial lower eyelid, nasal sidewall and infraorbital cheek following Mohs micrographic surgery for basal cell carcinoma (BCC).Materials and

Methods

All patients who underwent MCAF between 2012 and 2018 under the care of a single surgeon (LCA) were identified. The technique described in this report is a significant modification of the traditional cheek advancement flap. The MCAF was undertaken without subciliary or infraorbital incisions, less extensive dissection and use of flap advancement rather than rotation. A retrospective chart review was completed using a pro-forma which included risk factors for flap failure, early and late complications and additional reconstructive procedures. Patient satisfaction was rated using a five-point Likert-type scale.

Results

42 patients underwent the MCAF. Mean follow up was 28.4 months (±19.9 months). Early complications were found in 11.9% of the patients and resolved completely within the first four post-operative weeks. There were no long term complications secondary to the reconstruction. No lower eyelid ectropion was noted. 78.6% of the patients cited they were 'extremely satisfied' with the final cosmetic outcome.

Conclusion

The MCAF proves a valuable and safe option in periocular reconstructive surgery with excellent cosmetic results and no post-operative ectropion. The necessity for eyelid tightening as part of the reconstructive process should encourage oculoplastic surgeons to use the MCAF when reconstructing defects involving medial lower eyelid, infraorbital cheek and nasal sidewall.
