title: Laterality of sinonasal cancer and its aetiologic implications.
abstract: A study of the laterality of cancer arising in the nose and sinuses in Cape Town shows that ethmoid tumours have a pronounced left-sided dominance irrespective of histology or racial group. This supports an exogenous cause for this site. These findings are discussed in the light of results from other clinical and epidemiological research. It seems unlikely that maxillary sinus cancer has the same aetiology as ethmoid carcinoma.
