Area of Science:

  • Oral and Maxillofacial Surgery
  • Plastic Surgery
  • Aesthetic Surgery

Background:

  • Macrogenia, characterized by an excessively large chin, presents aesthetic challenges.
  • Surgical correction often involves complex osteotomies of the mandibular inferior border.

Purpose of the Study:

  • To present a comprehensive treatment protocol for macrogenia.
  • To evaluate the efficacy and safety of semicircular ostectomy for mandibular reduction.

Main Methods:

  • A cohort of seven patients with macrogenia underwent treatment.
  • The protocol included Delaire analysis for preoperative assessment, 3D reconstruction and simulation for operative design, and semicircular ostectomy of the mandibular inferior border.
  • Postoperative evaluation assessed aesthetic outcomes and complications.

Main Results:

  • The treatment protocol harmonized the lower facial contour in all patients.
  • All seven patients reported high satisfaction with their aesthetic results.
  • Minor complications like temporary numbness and submental soft-tissue excess were observed and showed improvement over time.

Conclusions:

  • The developed treatment protocol enables precise and safe surgical correction of macrogenia.
  • Semicircular ostectomy is an effective technique for improving facial aesthetics in macrogenia patients.
  • The protocol leads to satisfactory functional and aesthetic outcomes.
