Retrospective Analysis of Complication Rates Associated With Auricular Reconstruction After Skin Cancer Surgery.

Background: There is limited data regarding postoperative complications after microtia surgery or tympanoplasty; however, complication rates after pinna reconstruction following tumor resection and comorbidities associated with suboptimal outcomes have not been investigated so far.

Objective: To examine the incidence of postoperative complications after auricular reconstruction surgery following tumor resection and determine the association between postoperative complications and defect size, patients' comorbidities, and reconstruction type.

Methods And Materials: In a retrospective case series ( = 146, January 2014 to October 2018), we examined the surgical outcome and amount of postoperative complications following auricular surgery as well as the association with different comorbidities. SPSS 16.0 was used for statistical analyses.

Results: The following early postoperative complications were identified: pain (29.5%), hematoma (4.1%), flap congestion (4.8%), infection (3.4%), and flap/graft necrosis (2.7%). Late complications including cartilage step-offs, helical rim sulcus alteration, granulomas, or ear deformities occurred only in 3.6% of subjects. Reconstructions of large defects (>1 cm) were associated with a higher incidence of early postoperative complications compared to small defects (<1 cm) ( < .001). Neither the presence of smoking or diabetes nor immunosuppression was significantly linked to an increased incidence of early complications. Immunosuppression, however, was associated with a higher incidence of postoperative infection ( < .001).

Conclusion: The incidence of early and late postoperative complications after skin tumor resection and external ear reconstruction is low. The occurrence of postoperative infection was not linked with smoking or the presence of diabetes, but strongly associated with a state of immunosuppression, which is why a perioperative antibiotic prophylaxis in immune-compromised patients may be considered.
