Which factor is NOT considered when evaluating eyelid tumors?

In the evaluation of eyelid tumors, several factors are critically examined to determine the potential impact on a patient's ocular health and to guide treatment decisions. The factors typically considered include the size of the tumor, its effect on the ocular surface, and whether it involves adjacent structures such as the nasolacrimal ducts or canthus.

The size approaching one-third of the lid margin is significant because larger tumors can lead to functional issues with eyelid closure and increased risk of exposure-related complications. Irritation to the ocular surface caused by a tumor can lead to corneal damage or secondary infections, making this a crucial consideration as well. Similarly, involvement of the nasolacrimal ducts or canthus is particularly relevant because it can affect tear drainage and contribute to ocular surface disease.

However, the involvement of the nasal passages is not typically a direct consideration for eyelid tumors. While it is relevant in the context of certain tumor types and their potential spread or association with other pathologies, the evaluation of eyelid tumors primarily focuses on factors that directly affect the eyelid structure and function, not on their relation to the nasal passages. Therefore, this factor is not standard in evaluating eyelid tumors specifically.
