Ring Dehiscence From Right Fibrous Trigone Misidentification

Key Points

• To assess the importance of correct trigonal engagement in preventing ring dehiscence and malposition.
• Analysis of trigonal structures during surgical procedures
• Comparative assessment of ring placements with correct and incorrect engagement
• Evaluation of outcomes associated with misidentification of the right fibrous trigone.
• Improper trigonal engagement significantly increased the risk of ring dehiscence.
• Correct identification of the right fibrous trigone led to improved stability of the ring.
