Outcome of patients presenting with preauricular sinus in a tertiary centre--a five year experience.
We reviewed the recurrence rate and possible factors influencing recurrence of preauricular sinus after excision. Seventy-one patients with 73 preauricular sinuses seen at our centre from year 2000 to 2005 were reviewed in this study. The overall recurrence rate was 14.1%. Twelve sinuses needed to be drained for an abscess prior to a definitive surgery. Different modalities used in demonstrating the sinus tract between methylene blue alone and probing together with methylene blue, showed different outcomes, which were statistically significant with a p value of < 0.05(chi-square test). A preauricular sinus with a previous history of infection or actively infected during the definitive surgery may have a higher tendency of recurrence. Meanwhile demonstrating the sinus tract by probing with lacrimal probe/sinus probe followed by injection of methylene blue reduces the recurrence rate (p < 0.05 with chi-square test).
