A Case of Zygomatic Osteomyelitis Complicating Preseptal and Postseptal Abscess / 대한이비인후과학회지

ABSTRACT

The most common cause of orbital in/fection is a sinusitis, and if this orbital complication is not provided with appropriate and intensive treatments, serious status such as visual loss or life-threatening may occur. Osteomyelitis rarely results from sinusitis, and in cases where it happens, the frontal sinus is the most frequently involved site. However, zygomatic osteomyelitis has not been reported so far. We present a case of maxillary sinusitis which was initiated by oroantral fistula, and developed to preseptal and postseptal abscess, penetrating into the orbital septum. The case was complicated by zygomatic osteomyelitis. This case was successfully treated by draining pus by endonasal endoscopic sinus surgery, infraorbital incision, and was followed by antibiotic therapy for about 8 weeks.
