Summary
Frontoethmoidal mucoceles invading the skull base or orbits are challenging. Surgical approaches, guided by CT scans, vary based on mucocele extent, with potential complications like abscesses or CSF leaks.
Area of Science:
- Neurosurgery
- Otolaryngology
- Radiology
Background:
- Frontoethmoidal mucoceles are benign cysts that can invade critical structures.
- Invasion into the anterior cranial fossa or orbits presents significant management challenges and risks lethal complications.
Observation:
- Nine cases of frontoethmoidal mucoceles were treated over four years.
- Five cases involved invasion of the anterior cranial fossa, orbits, or both.
Findings:
- Surgical management depended on mucocele extent and location, determined by computed tomography (CT).
- Procedures included craniotomy with pericranial flap reconstruction, osteoplastic flap with fat obliteration, and intranasal drainage.
- Complications observed were an intracranial abscess and a cerebrospinal fluid leak.
Implications:
- Accurate CT imaging is crucial for selecting appropriate surgical interventions for invasive frontoethmoidal mucoceles.
- Multidisciplinary surgical approaches are necessary for complex cases.
- Awareness of potential surgical complications is vital for patient management.
