Summary

Surgical excision of preauricular sinuses can lead to defects requiring reconstruction. This study evaluates primary closure versus posterior auricular flaps for effective preauricular defect repair.

Area of Science:

  • Plastic Surgery
  • Congenital Abnormalities
  • Reconstructive Surgery

Background:

  • Preauricular sinuses are congenital abnormalities of ear development.
  • Inflammation necessitates surgical excision, often resulting in challenging defects.
  • Effective reconstruction techniques are crucial for managing post-excision preauricular defects.

Purpose of the Study:

  • To evaluate surgical techniques for reconstructing preauricular defects following sinus excision.
  • To determine the optimal method for closing defects based on their characteristics.

Main Methods:

  • Retrospective analysis of 28 cases undergoing preauricular sinus excision.
  • Surgical closure involved either primary closure (simple sutures or wide undermining) or posterior auricular transposition flaps.

  • Decision for closure method based on defect depth and wound margin tension.

    • Main Results:

    • Primary closure with simple sutures was used in 16 cases.
    • Wide undermining preceded primary closure in 7 cases.
    • Posterior auricular transposition flaps were utilized in 5 cases, including reoperations for dehiscence.

    Conclusions:

    • Primary closure is suitable for superficial defects with minimal tension.
    • Wide undermining is recommended for deeper defects or those with tension.
    • Posterior auricular flaps are indicated for extensive defects, cartilage exposure, or post-primary repair complications.
