The Effects of Primary Defect Characteristics on Reconstruction Type and Adjunctive Intervention in Mohs Micrographic
Background:
Cosmetic concerns following Mohs Micrographic surgery (MMS) are significant and may require adjunctive treatments for unsatisfactory appearance.
Objective:
To determine factors associated with adjunctive cosmetic intervention for facial defects following MMS.
Methods And Materials:
A retrospective review of 699 patients undergoing repair of facial defects after MMS from 2008-2018 was performed. Tumor types, defect sizes, patient demographics, repair methods, complications, and post-operative cosmetic interventions were examined.
Results:
666 Mohs cases and resultant defects were analyzed. The most common method of repair following MMS was primary closure (52.3%), and the most common post-operative intervention was steroid injection (18.3%). The lip subunit was more than twice as likely as other locations to be treated with steroid injections (P<.001). The lip subunit also had the highest frequency of scar revision (13%; P<0.001). Patients who had primary closure were less likely to require scar revision (P=0.003) or dermabrasion (P=0.042), and there was no significant association between skin graft repair and cosmetic intervention.
Conclusions:
Both defect subunit and closure type were independently associated with adjunctive cosmetic intervention following MMS. Defect size was not significantly associated with an adjunctive intervention in our study. Understanding the factors affecting the need for adjunctive cosmetic interventions may improve patient counseling prior to Mohs repair. J Drugs Dermatol. 2020;19(3): doi:10.36849/JDD.2020.4701.
