Bridge of bone canthopexy: technique and morphologic assessment

Area of Science:

• Oculoplastics
• Facial Plastic Surgery
• Ophthalmology

Background:

• Lower eyelid malposition negatively impacts facial aesthetics and eyelid function.
• Various surgical methods exist to correct lower eyelid malposition.
• This study focuses on a modified bridge of bone canthopexy technique.

Purpose of the Study:

• To present a modified bridge of bone canthopexy technique.
• To evaluate the efficacy of this technique in restoring lower eyelid position.
• To assess its impact on palpebral fissure dimensions.

Main Methods:

• Retrospective chart review of 12 patients undergoing the procedure.
• Pre- and post-operative photographs analyzed by a blinded observer.
• Statistical analysis using pair-wise and chi-square tests (p<0.05 significant).

Main Results:

• Significant reduction in canthal tilt and scleral show post-surgery (p=0.05).
• Eye fissure index and inferior iris coverage showed trends towards improvement (p=0.16, p=0.07).
• Two minor complications were reported in the patient series.

Conclusions:

• The modified bridge of bone canthopexy is a safe and effective method for correcting lower eyelid malposition.
• The technique is versatile and applicable to various causes of negative canthal tilt.
• Further research is needed to confirm long-term outcomes and procedural stability.
