Algorithm of surgical treatment of the Pott's tumor
Pott's puffy tumor (PPT) is a frontal subperiosteal abscess associated with underlying frontal bone osteomyelitis. It is most common among children and adolescents. Trauma and recurrent sinusitis may be the trigger factors for the abscess formation. The main causative pathogens belong to the groups of streptococci, staphylococci and anaerobes. In the early stages, intracranial complications often appear asymptomatic, especially if the abscess is localized in the cortex. Early diagnosis of PPT is crucial for recovery and minimization of long-term complications. In this article we describe the case of a 55-year-old woman with an exacerbation of chronic sinusitis complicated by Pott's tumor. The peculiarity of the case lies in the inflammatory process in the paranasal sinuses which proceeded for a long time despite antibacterial therapy and led to the gradual formation of the abscess and fistula in 2-3 days. Conservative treatment of the patient failed, and FESS was required. Endoscopic fronto-ethmoidotomy was performed with the assistance of a navigation system. The purpose of the surgery was to adequately drain the abscess and restore the nasofrontal duct. The timely and optimal surgical treatment allows avoiding serious complications of both the disease itself and the treatment
