Pott's puffy tumor 様腫脹を認めた外傷性前頭洞炎の一例 Traumatic Frontal Sinusitis Presenting as Pott's Puffy Like Tumor. Case Report
We report a case of the traumatic frontal sinusitis presenting as Pott's puffy tumor-like frontal subcutaneous abscess. A 39-year-old man with frontal swelling and pain consulted the emergency unit of our university. The patient had a history of epidural abscess and frontal sinusitis after a traffic injury. Computed tomography scans demonstrated severe deformation of the left facial bone, including the orbit, a soft tissue density in the left frontal sinus, and a frontal subcutaneous abscess. We performed drainage surgery on the abscess on the day of the initial visit, but his symptoms recurred twice, and a total of three operations were performed. During the third operation, we performed endoscopic frontal median drainage (Draf type III) and inserted a T-shaped silicone tube in the dilated nasofrontal duct. The frontal swelling and pain resolved postoperatively, and the patient has been symptom-free during the 1-year of follow-up. The intractability of this case may have been due to the severe deformation of the frontal sinus and facial bone caused by the traffic injury. Median frontal drainage with insertion of a T-shaped silicone tube was effective even in such severe frontal sinus disease.
