[Osteomyelitis of right frontal sinus anterior wall].

INTRODUCTION

The paper describes a very rare, isolated exocranial complication of the purulent frontal sinus inflammation. Frontal bone osteomyelitis occurs either in the course of an acute episode or during the exacerbation of a chronic disease. By distribution, it can be diffuse or circumscript. It is more common in younger males.

CASE OUTLINE: The case described is one of a 43-year-old patient with purulent frontal sinusitis developing into osteomyelitis of the anterior wall of the right frontal sinus, accompanied by the exteriorisation of the process into the frontal region soft tissues. The classical paranasal sinus radiography did not find any pathological changes in bony structures. Computerised tomography findings pointed to purulent inflammation of the frontal and part of the ethmoid sinuses, with a defect of the anterior wall of the right frontal sinus.

CONCLUSION

Surgical exploration established a defect in the anterior wall of the right frontal sinus, with an organised purulent collection, 1.3 cm in diameter. During surgery, evacuation of the inflamed mucosa and obliteration of the right frontal sinus were performed. Having analysed the anamnestic data, radiography and laboratory results, and intraoperative findings, we were not able to conclude decisively whether it was a complication of acute or chronic inflammation.
