Summary
Pneumosinus dilatans, a rare frontal sinus disorder, involves abnormal enlargement due to hyperpneumatization. Surgical correction addresses both the cosmetic deformity and the underlying valve mechanism causing increased sinus pressure.
Area of Science:
- Otolaryngology
- Plastic Surgery
- Radiology
Background:
- Pneumosinus dilatans is a rare condition characterized by frontal sinus enlargement due to hyperpneumatization.
- It is most prevalent in males aged 20-40 and is often linked to an internal valve mechanism that increases sinus pressure.
Observation:
- A case study of a 25-year-old male with pneumosinus dilatans is presented.
- Preoperative computed tomography (CT) scans in three planes were utilized to delineate anatomical details and potential etiological factors.
Findings:
- The study details a surgical approach to correct the esthetic deformity and the underlying cause of pneumosinus dilatans.
- An osteoplastic correction, stabilized with titanium micro-osteosynthesis plates, was performed via a bicoronal incision for optimal frontal sinus exposure.
Implications:
- The surgical technique aims for both functional and cosmetic improvement in patients with pneumosinus dilatans.
- Concomitant functional endoscopic sinus surgery is recommended to address the root cause of the condition, preventing recurrence.
