The ­authors ­report a ­case of cemen­to-ossi­fy­ing fibro­ma of ­the super­i­or max­il­lary ­bone, ­which invad­ed ­the max­il­lary ­sinus bilat­er­al­ly. Surgery ­was per­formed by an intra­oral inci­sion on ­the ­left ­and ­the arrange­ment of a ­flap accord­ing to Weber-Fergusson on ­the ­right. Histologic fea­tures ­and ­the inves­ti­ga­tions ­required to ­reach a cor­rect diag­no­sis ­are ­described. A 12-month fol­low-up ­showed a com­plete resti­tu­tio ad inte­grum ­with a nor­mal pneu­mat­iza­tion of ­the max­il­lary sinus­es ­and sat­is­fac­to­ry resid­u­al scar­ring. It is a ­fibro-­osseous ­lesion, ­with a ­slow ­growth, ­which ­can ­lead to a defor­mity of ­the affect­ed ­bone result­ing in aes­thet­ic ­and/or func­tion­al alter­a­tions. Descriptions of bilat­er­al cemen­to-ossi­fy­ing fibro­ma ­are uncom­mon. The dif­fe­ren­tial diag­no­sis ­must be deter­mined ­with oth­er pathol­o­gies, ­such as chron­ic osteo­my­e­li­tis, per­i­os­teitis, Paget’s dis­ease, hyper­pa­rath­yr­oi­dism, oste­o­blas­to­ma ­and ­low ­grade oste­o­sar­co­ma. The prog­no­sis is excel­lent ­and relaps­es ­are uncom­mon.
