Since the discovery of the two BER pathways, there has been a debate about how a cell chooses one pathway over the other and the factors determining this selection. Numerous in vitro experiments have pointed out multiple determinants for the sub-pathway selection. These are:

Area of Science:

  • Maxillofacial Surgery
  • Orthodontics
  • Plastic Surgery

Background:

  • Chin surgery, including mandibular symphysis advancement, has been used for facial abnormalities, snoring, and obstructive sleep apnea.
  • Patients with orthodontic compensation but facial dissatisfaction and airway issues require tailored surgical solutions.

Purpose of the Study:

  • To introduce and evaluate the Basal Extended Mentoplasty (BEM) technique.
  • To address the needs of orthodontically compensated patients with labial incompetence and Class II skeletal discrepancies.

Main Methods:

  • Retrospective analysis of 65 patients operated between 2015-2019.
  • Focus on eight cases presenting labial incompetence and Class II skeletal patterns.

Main Results:

  • Successful osseointegration and adequate lower third facial projection were observed.
  • Achieved 0 mm interlabial gap, indicating proper lip competence.

Conclusions:

  • Basal Extended Mentoplasty (BEM) provides mandibular lengthening for specific patient groups.
  • The technique results in harmonious facial balance and profile with no reported nerve or vascular complications.
