Diagrams depicting the evolution of a mucocoele.
- Figure 1: Normal paranasal sinuses
- Figure 2: Obstruction of the ostium results in gradual opacification of the sinus.
- Figure 3: Complete opacification of the sinus with gradual increase in pressure.
- Figure 4: Final stage of mucocoele formation, demonstrating bony expansion of the sinus.
