Description
Estimated cost for Orthognathic surgery at general public hospitals in China is about ¥24500-52000, and at Grade 3A hospitals about ¥35000-65000, varying by hospital tier and region.
Main Uses
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.
Normal Range
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.
Low Values - Possible Causes
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.
High Values - Possible Causes
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.
