Descrição
Procedimento cirúrgico que corrige simultaneamente as posições dos maxilares superior e inferior para tratar desvios esqueléticos, melhorando função mastigatória, oclusão dentária e estética facial.
Principais Usos
Primary clinical uses include correction of severe dentofacial deformities unresponsive to orthodontics alone—such as Class III malocclusion with mandibular prognathism, Class II deformity with maxillary retrognathia, open bite with vertical excess, facial asymmetry, obstructive sleep apnea related to retrognathia, and functional impairment (e.g., difficulty chewing, speaking, or breathing). It is indicated after completion of skeletal growth (typically age ≥17 years) and integrated with pre- and post-surgical orthodontics.
Faixa Normal
Bimaxillary surgery (double-jaw surgery) is a surgical procedure, not a laboratory or diagnostic test with numerical values; therefore, it has no 'normal range' of quantitative indicators. Clinical assessment relies on cephalometric measurements (e.g., SNA 82°±2°, SNB 80°±2°, ANB 2°±2°), dental models, 3D imaging metrics, and functional occlusion criteria — all interpreted by craniofacial surgeons and orthodontists within individualized treatment plans.
Valores Baixos - Possíveis Causas
N/A — As a surgical intervention, 'low values' do not apply. However, suboptimal surgical outcomes (e.g., insufficient advancement, undercorrection of skeletal discrepancy, inadequate genioplasty adjustment, or poor soft-tissue adaptation) may result from inaccurate preoperative planning, intraoperative measurement error, intraoperative anatomical constraints, or unexpected bone healing patterns.
Valores Altos - Possíveis Causas
N/A — As a surgical intervention, 'high values' do not apply. However, overcorrection (e.g., excessive maxillary advancement, excessive mandibular setback, or over-rotated occlusal plane) may occur due to miscalibrated surgical guides, intraoperative misjudgment of reference points, software errors in virtual surgical planning, or compensatory intraoperative adjustments without real-time verification.
