Plain-English summary
A 3-month-old male Great Dane puppy was brought in with a bulging left eye, excessive tearing, and swelling on the left side of his forehead. X-rays showed that the left frontal sinus was blocked and thickened, indicating a serious infection. During surgery, the vet found the sinus filled with soft bone and pus, which was caused by bacteria. The infected bone was removed, and the area was repaired using a muscle flap. After treatment, the puppy's condition improved, and he was on the road to recovery.

Abstract
A three-month-old, male Great Dane puppy developed progressive left exophthalmos, epiphora, and swelling of the left frontal bone. Radiographs revealed obliteration of the left frontal sinus by a bone-like density, and lateral sinus wall thickening with extension into the left orbit. On surgical exploration and trephination, the left frontal sinus was filled with soft bone which contained multiple pockets of mucopurulent material. Cytologic examination confirmed the presence of a large number of neutrophils, osteoclasts, and osteoblasts; and both extracellular and intracellular, filamentous, beaded bacteria. The involved bone was debrided, and the defects in the orbital wall and sinus were reconstructed successfully with a temporalis muscle flap.
