Comparative study of pre- and postauricular flaps for external auditory canal defect reconstruction

Area of Science:

• Plastic Surgery
• Oncology
• Otolaryngology

Background:

• Malignancies of the external auditory canal require careful management due to functional and aesthetic considerations.
• Flap reconstruction is a key method for restoring defects of the external auditory canal.
• Various flap options exist for surgical repair of external acoustic meatus defects.

Purpose of the Study:

• To compare the aesthetic and functional results of preauricular flap versus postauricular revolving door flap reconstruction for external auditory canal defects post-skin cancer excision.

Main Methods:

• A retrospective study included sixteen patients with external auditory canal defects from skin cancer excision.
• Patients were divided into two groups: one receiving preauricular flap reconstruction, the other postauricular revolving door flap reconstruction.
• Outcomes were assessed using visual analog scales.

Main Results:

• Both flap techniques yielded excellent aesthetic and functional results.
• The postauricular revolving door flap demonstrated slightly superior outcomes.
• The postauricular revolving door flap offered improved aesthetics due to scar concealment.

Conclusions:

• Both preauricular and postauricular revolving door flaps are viable options for external auditory canal reconstruction.
• The postauricular revolving door flap provides a more natural appearance and movement without an external pedicle.
