Scar outcomes in dermatological surgery

Abstract

Background/Objectives

Significant functional impairment and psychological burden may result from poor scar quality and its impact on patient's quality of life has been well-established. It is important to identify measures to reduce the risk of surgical complications.

Method

212 patients undergoing dermatological surgery were recruited from March 2011 to February 2014. Their age, sex, surgical site, closure type, defect size (length and width), scar length, number of deep sutures, suture type and size were recorded. The patients were followed up at 6 weeks and 6 months for complications including abscess formation, granuloma formation, scar spreading, suture spitting and hypertrophic scar formation.

Results

At 6 weeks complications included suture spitting (14%), granuloma (11%), scar spreading (7%), hypertrophic scarring (3%) and abscess formation (1%), and at 6 months; scar spreading (17%), hypertrophic scarring (2%) and suture spitting (1%). In our multivariate analysis there were no predictors for spreading or spitting at 6 weeks, and only the defect size width was a predictor for granulomas in the stepwise analysis. For scar spreading at 6 months, younger age, site (trunk or limbs), higher number of deep sutures and surgeon were independent predictors (P < 0.0001 for the model).

Conclusion

Complications following dermatological surgery are low and tend to resolve with time, except for scar spreading. The surgeon who experienced more complications was placing sutures more superficially to the skin surface and was throwing more knots per closure; factors that we did not record in our study and merit further study.
