Explanation

A tumor infiltrating the foramen ovale can lead to anesthesia of the TMJ, paralysis of the tensor tympani, and paralysis of the stylohyoid muscle due to involvement of the mandibular nerve branches. However, it does not cause abnormal or altered sensation (paresthesia) of the lips, as this is typically related to other nerve pathways.
