Description
A 59-year-old man with angina visited our department with fever and facial pain. Clinically, his left cheek showed diffuse swelling with slight erythema (figure 1A). There was no toothache, although tooth contamination and gingival swelling were observed in the maxilla (figure 1B). CT findings revealed osteolysis of the root of a tooth, but there is no maxillary sinusitis.
(A) Diffuse swelling with slight erythema was observed on his left cheek. (B) Tooth contamination and gingival swelling were observed in the maxilla (white arrow).
We diagnosed facial cellulitis associated with apical periodontitis. Puncture drainage through the apex and systemic antibiotics quickly improved the symptoms.
Facial cellulitis can occur due to acute sinusitis, apical periodontitis, otitis externa, trauma, insect bites, conjunctivitis or blepharitis. It should be noted that the odontogenic infection is sometimes asymptomatic.
Therefore, clinicians should pay careful attention to the medical history and oral examination of patients with facial cellulitis.1
Patient’s perspective
I visited to the hospital because my face was swollen, but I didn't think it was due to caries because there is no pain in my teeth.
Learning points
In cases of facial cellulitis, it can arises from acute sinusitis, apical periodontitis, otitis externa, trauma, insect bites, conjunctivitis or blepharitis.
Odontogenic infections are sometimes asymptomatic and easily missed as infected foci.
