Background: Auricular/nasal basal cell carcinomas (BCC) often require more surgical procedures than BCCs at other sites.
Methods: A meta-analysis of incompletely excised BCCs compares those on the ear and nose to other sites. The combination of photodynamic diagnostics (PDD) and fresh-frozen sections is compared to multi-stage excisions; in each case, the tissue margins were histographically controlled.
Results: The relative risk of an incomplete excision of a BCC on the ear/nose is 2.5 fold higher than on the rest of the body. The combination of PDD and micrographic surgery with fresh-frozen sections reduces the length of stay by 42.86 % from median 14 d to 8 d as well as increasing the revenue per patient per day by 41.9 % from 320.61 euro to 454.95 euro with nearly a comparable rate of recurrences after one year.
Conclusions: PDD in combination with single-stage surgery is an equivalent therapy with few side effects and conforming to guidelines. It takes into account both quality assurance and patient preferences. Multicenter, randomized trials seem desirable.
