Long-term results after lateral canthal advancement for unilateral coronal synostosis
1Department of Surgery, Hospital for Sick Children, Toronto, Ontario, Canada.
Insights
Lateral canthal advancement effectively corrects unilateral coronal synostosis in children, with 81% achieving good or excellent outcomes. This surgical technique is recommended due to minimal morbidity and continuous improvement observed over time.
Area of Science:
- Neurosurgery
- Pediatric Plastic Surgery
- Craniofacial Surgery
Background:
- Unilateral coronal synostosis presents significant aesthetic and functional challenges.
- Surgical correction aims to normalize skull shape and improve facial symmetry.
- Previous methods have limitations in addressing the complex craniofacial deformities.
Purpose of the Study:
- To evaluate the efficacy and outcomes of lateral canthal advancement for unilateral coronal synostosis.
- To identify critical surgical steps for successful outcomes.
- To determine patient factors influencing treatment success.
Main Methods:
- A retrospective review of 39 consecutive patients undergoing lateral canthal advancement.
- Surgical technique involved liberation of the supraorbital margin and release of stenotic skull base sutures.
- Follow-up assessment of 37 patients for aesthetic and functional results.
Main Results:
- 81% of patients achieved good or excellent outcomes.
- Minimal morbidity was associated with the procedure.
- Continuous improvement was observed in some patients over time.
- Severity and age were not restrictive factors for surgical indication.
Conclusions:
- Lateral canthal advancement is a highly effective procedure for unilateral coronal synostosis.
- Liberation of the supraorbital margin and skull base suture release are key to success.
- The procedure is well-tolerated with minimal complications and offers long-term benefits.
Abstract:
The procedure of lateral canthal advancement was carried out to correct unilateral coronal synostosis in 39 consecutive patients at The Hospital for Sick Children during a 20-year period. Thirty-seven children were available for follow-up study, and results were considered to be good or excellent in 81% of them. Liberation of the supraorbital margin and release of stenotic skull base sutures are crucial for a successful result. The severity of the process and the age of the patient were not restrictive factors in regard to indication for this procedure. Some patients showed a continuous improvement with time. Morbidity was minimal. It is suggested that lateral canthal advancement is the procedure of choice for unilateral coronal synostosis.
