Findings:
Mucoperiosteal thickening and complete opacification of the frontal sinuses on the left sphenoid sinus is noted. Mucoperiosteal thickening and subtotal obliteration of the ethmoid and maxillary sinuses bilaterally. Mild mucosal thickening is also seen in the right sphenoid sinus.
The ostio-meatal units, sphenoethmoidal recesses and frontal outflow tracts are compromised with thickened mucosa and retained secretions.
Multiple polypoid soft tissue lesions are noted in bilateral nasal cavities. Consequential partial blockage of the nasal cavities bilaterally.
There is demineralization of ethmoid bone septae, nasal conchae, uncinate processes and medial wall of both maxillary sinuses. Also, thinning and demineralization of orbital and cribriform plates is seen bilaterally. Keros type I.
Nasal septum is deviated to the right.
The orbits have a normal appearance, as does the nasopharynx and visualised oropharynx.
Previous extraction of the left upper first molar with residual root fragment remaining in the socket.
Postinflammatory sclerosis of the right mastoid process is seen. The mastoid air cells and the middle ear cavities are clear.
Conclusion:
Chronic pansinusitis due to extensive sinonasal polyposis.
Residual root fragment remaining in the socket of the left upper first molar.
