In 1974-1991 the authors followed up 402 and 220 patients with odontogenic and rhinogenic maxillary sinusitis, respectively. It is confirmed that the leading cause of odontogenic sinusitis is periapical inflammation, while perforation of the sinus base in removal of the tooth is the sequela. In dissection of the sinus base free of sinusitis suturing of the hole or its closure with mucoperiosteal graft may warrant the clot persistence in the hole. Injuries of the sinus base are divided into chance and suspected, recognizable and missed, complicated and noncomplicated, perforation with complete and incomplete tooth removal. Therapeutic policy should be designed on the individual basis depending on the odontogenic cause. |
