Summary

Two surgical techniques address bird-face deformity by lengthening the jaw. Both involve advancement genioplasty, differing in how the mandibular body is elongated to correct micromandibularism.

Area of Science:

Oral and Maxillofacial Surgery
Plastic Surgery
Craniofacial Surgery

Background:

Bird-face deformity, characterized by micromandibularism, presents aesthetic and functional challenges.
Symmetric and asymmetric presentations require tailored surgical correction.
Current surgical options aim to achieve mandibular elongation and facial balance.

Purpose of the Study:

To describe and compare two distinct surgical procedures for correcting bird-face deformity.
To illustrate the application of these techniques in both symmetric and asymmetric cases.
To detail the methods for mandibular body elongation in each procedure.

Main Methods:

Procedure 1: Elongation of the mandibular body posterior to the tooth-bearing area using extended sagittal split osteotomy.
Procedure 2: Elongation of the mandibular body within the tooth-bearing area via vertical osteotomy.
Both procedures incorporate one- or two-step advancement genioplasty for anterior elongation.

Main Results:

Both described procedures effectively correct micromandibularism in bird-face deformity.
Illustrative cases and surgical drawings demonstrate the practical application of each technique.
The primary distinction lies in the location of mandibular body elongation (posterior vs. intra-osseous).

Conclusions:

Two viable surgical approaches exist for correcting bird-face deformity.
Choice of procedure depends on the specific method for mandibular body elongation.
Both techniques, combined with advancement genioplasty, offer solutions for symmetric and asymmetric presentations.
