A

Hx of chronic sinus congestion recurrent nasal obstructionNasal dischargeintermittent epistaxis unilateral symptoms

94
Q

what are the symptoms of advanced lesions?

A

It depends on where the tumor has spread:1. widening of the bride of the nose2. Frontal headaches3. proptosis (eyes pushing out), diplopia or palpable orbital mass

95
Q

what doeswidening of the bride of the nose indicate?

A

the lesion is invading the olfactory region

96
