A new aesthetic pretrichial approach for upper third-facial fractures and pathologies: The "Crown incision".

Abstract

The coronal incision represents the cornerstone for the treatment of upper-third maxillofacial pathologies. However, this approach leaves long scars that in numerous patients, it can cause extensive surrounding alopecia and sensory skin deficits. This clinical evidence prompted the authors to propose a full pretrichial incision, the crown incision, in order to overcome these drawbacks. A retrospective study was performed to investigate and report the aesthetic and functional outcomes of 15 patients treated with this new approach. In the postoperative period, no major or minor complications were detected. The aesthetic evaluation of the scar by the operator and the patient showed overlapping results. The overall rating was 2.93 for the patient and 2.87 for the surgeon, on a scale from 0 (as normal skin) to 10 (very different from normal skin). The recovery of sensitivity in the innervation territories of the supratrochlear and supraorbital nerves was found to be complete in 14 patients. In one case, the sharp/blunt discriminative sensitivity was absent in all three points assessed. This study showed the crown incision to be a safe approach with an optimal recovery of scalp sensitivity and excellent aesthetic results even in bald patients. Therefore, it can be considered a valid aesthetic and effective alternative to the classic coronal approach and should form part of the craniomaxillofacial surgical armamentarium.
