Incomplete excision of basal cell carcinoma in the subunits of the nose

Reconstructive procedures after resection of nasal basal cell carcinoma (BCC) vary depending on the subunit involved. The aim of the present study was to assess the influence of the location of the BCC on the rate of incomplete excisions, so we made a retrospective analysis of all nasal BCC excised at our hospital between 2002 and 2005. The incomplete excision rate was 24/148 (16%). More incomplete excision occurred on the alae (n=13) when compared to the dorsum (n=2) of the nose (p<0.05). Eight two-staged procedures resulted in incomplete resection, whereas 9 (6%) frozen section analyses were false-negative. BCC were most likely to be incompletely excised on the nasal tip and alae, and both subunits required more elaborate reconstructions. This, however, was not the result of poor estimation of the extent of the tumour and reluctance to excise more challenging areas widely for reconstruction, but to the method chosen to eradicate the tumour.
