Description
Estimated cost for Sagittal Split Ramus Osteotomy (SSRO) at general public hospitals in China is about ¥24500-36000, and at Grade 3A hospitals about ¥35000-45000, varying by hospital tier and region.
Main Uses
Single-jaw orthognathic surgery (specifically SSRO) is primarily used to correct dentofacial deformities involving the mandible, including mandibular retrognathia (underdevelopment), prognathism (overdevelopment), asymmetry, and open bite. It enables precise repositioning of the mandible for improved occlusion, airway function, mastication, speech, and facial aesthetics. Common indications include Class II or III skeletal malocclusions unresponsive to orthodontics alone, obstructive sleep apnea related to mandibular deficiency, and post-traumatic mandibular deformity.
Normal Range
SSRO is a surgical procedure, not a laboratory or diagnostic test with numerical values; therefore, there is no 'normal range' of quantitative indicators. Clinical success is assessed qualitatively via postoperative imaging (e.g., cephalometric analysis), occlusion evaluation, facial symmetry, and functional outcomes — not through numeric reference intervals.
Low Values - Possible Causes
N/A — SSRO is not a measurable biomarker or physiological parameter; 'low values' do not apply. Misinterpretation may arise from confusing SSRO with lab tests (e.g., calcium, vitamin D) or radiographic measurements (e.g., mandibular plane angle), but these are separate assessments unrelated to the surgical procedure itself.
High Values - Possible Causes
N/A — SSRO is a surgical intervention, not a quantifiable test; 'high values' have no clinical meaning in this context. Abnormal findings post-SSRO (e.g., excessive advancement, nerve injury, nonunion) reflect surgical complications—not elevated test values.
