Summary

Surgical treatment for preauricular sinus, a congenital ear condition, involves complete excision of the associated gland and duct. This one-stage procedure shows high efficacy, with minimal recurrence rates, even in infected cases.

Area of Science:

  • Otolaryngology
  • Surgical Anatomy
  • Congenital Malformations

Background:

  • Preauricular sinus is a common congenital anomaly.
  • It often presents with or without infection.
  • Understanding its anatomical relationship to the preauricular gland is crucial.

Purpose of the Study:

  • To evaluate a one-stage surgical technique for preauricular sinus.
  • To assess the efficacy of complete gland and duct excision.
  • To determine recurrence rates in treated preauricular sinuses.

Main Methods:

  • Surgical excision of the entire preauricular gland and duct.
  • Application of the technique to 56 sinuses in 44 patients.
  • Inclusion of infected and non-infected cases.

Main Results:

  • Three recurrences observed in 56 treated sinuses.
  • Two recurrences attributed to incomplete gland excision.
  • One recurrence linked to a fistula with atresia of the external auditory canal.
  • No recurrences in the majority of cases with follow-up of six months or longer.

Conclusions:

  • A one-stage surgical approach based on anatomical understanding is effective for preauricular sinus.
  • Complete excision of the gland and duct ensures high success rates.
  • The technique is suitable for treating preauricular sinuses at any stage, including infected ones.
