[Obliterating frontal sinus operation with abdominal fat. Follow-up with imaging methods]

Area of Science:

• Otolaryngology
• Neurosurgery
• Radiology

Context:

• Chronic frontal sinus disease presents a persistent clinical challenge.
• Surgical management often involves obliteration techniques to prevent recurrence.
• Long-term outcomes of frontal osteoplastic flap with fat obliteration require thorough evaluation.

Purpose:

• To assess the long-term efficacy and outcomes of frontal osteoplastic flaps with fat obliteration for chronic frontal sinus disease.
• To evaluate the correlation between clinical assessment, patient-reported symptoms, and imaging findings (CT and MR).

Summary:

• Ten patients with chronic frontal sinus disease underwent frontal osteoplastic flaps with fat obliteration between 1983 and 1991.
• Long-term follow-up included clinical assessment, questionnaires, computed tomography (CT), and magnetic resonance imaging (MR).
• Seven patients remained asymptomatic with no clinical evidence of disease; CT confirmed complete frontal sinus obliteration in all.
• Fat grafts were largely replaced by connective tissue.
• MR imaging did not correlate with symptoms and provided no additional diagnostic value compared to CT.

Impact:

• This study confirms the long-term clinical success of frontal osteoplastic flap with fat obliteration for chronic frontal sinus disease.
• Clinical assessment remains the primary determinant of surgical success in these cases.
• CT imaging is valuable for confirming sinus obliteration, while MR's role in this context is limited.
