Infratemporal pneumatocele arising from maxillary sinus.
Clinical Radiology
|January 1, 1992
Summary
Rare infratemporal fossa pneumoceles result from air escaping a damaged maxillary sinus. These cases highlight computed tomography
Area of Science:
- Otolaryngology
- Head and Neck Surgery
- Radiology
Background:
- Pneumatocele of the infratemporal fossa is an uncommon condition.
- It arises from air herniating through a defect in the maxillary sinus wall.
Observation:
- Two rare cases of infratemporal fossa pneumocele are presented.
- Case 1: Maxillary pneumocele with a zygomatic recess wall defect.
- Case 2: Maxillary radionecrosis with pathological fracture and infection.
Findings:
- Computed tomography (CT) effectively visualizes pneumocele extent.
- CT identifies associated maxillary pathology and causative bony defects.
- Treatment is tailored to patient condition, pathology, and defect size.
Implications:
- Highlights the utility of CT in diagnosing complex infratemporal fossa pathology.
- Emphasizes the varied etiologies and management considerations for these rare lesions.
- Informs surgical and radiological approaches to infratemporal fossa air entrapment.
