Preauricular sinuses in the pediatric population: techniques and recurrence rates

Area of Science:

• Otolaryngology
• Pediatric Surgery
• Surgical Outcomes

Background:

• Preauricular sinus is a common congenital anomaly in children.
• Surgical excision is the primary treatment for preauricular sinus.
• Various techniques exist for sinus tract visualization during surgery.

Purpose of the Study:

• To compare the outcomes of two surgical techniques for preauricular sinus management in pediatric patients.
• To evaluate recurrence and complication rates associated with microscope-guided versus methylene blue dye-guided excision.
• To identify factors influencing surgical success in pediatric preauricular sinus cases.

Main Methods:

• Retrospective review of clinical records for pediatric patients undergoing preauricular sinus excision.
• Categorization into two groups: microscope guidance and methylene blue dye/probe guidance.
• Follow-up via phone interview to ascertain recurrence and complications.

Main Results:

• 208 patients included; 114 in microscope group, 94 in methylene blue group.
• Overall recurrence rate was 2.4%, overall complication rate was 6.3%.
• Microscope group showed a significantly lower recurrence rate (0.9%) than the methylene blue group (4.3%).

Conclusions:

• Both microscope and methylene blue guidance result in low recurrence and complication rates for pediatric preauricular sinus surgery.
• Microscope-guided surgical excision demonstrates a statistically significant lower recurrence rate compared to methylene blue dye and probe guidance.
• Surgical technique for visualization is a key factor in minimizing recurrence in preauricular sinus management.
