Suggest Treatment Required For The Following CT Scan Results

the CT scan shows these results , what is the treatment ?? There is high attenuation within the left frontal sinus, may suggest chronic sinus disease likely fungal in origin, in addition there is a heterogeneous expansile mass involving the left frontal sinus that extends to the anterior ethmoid air cells, with a mixed sclerotic lytic pattern, with poorly differentiation of the ponto/medullary region, without any evidence of bony destruction or cortical disruption, appearance is most likely consistent with fibrodysplasia. The remaining of the visualized paranasal sinuses demonstrate unremarkable right maxillary sinus, sphenoid sinus and posterior ethmoid air cells.
