Introduction

Orthognathic surgery is generally categorized into Le Fort I osteotomy of the maxilla, sagittal split ramus osteotomy of the mandible, and bimaxillary surgery, with corresponding costs as follows: Le Fort I osteotomy of the maxilla, 30,000–60,000 yuan per procedure; sagittal split ramus osteotomy of the mandible, 40,000–80,000 yuan per procedure; bimaxillary surgery, 60,000–100,000 yuan per procedure.

Orthognathic surgery is generally categorized into three types: Le Fort I osteotomy of the maxilla, bilateral sagittal split osteotomy (BSSO) of the mandible, and bimaxillary surgery. The corresponding costs are as follows: Le Fort I osteotomy of the maxilla, 30,000–60,000 RMB per procedure; BSSO of the mandible, 40,000–80,000 RMB per procedure; and bimaxillary surgery, 60,000–100,000 RMB per procedure. Factors influencing the cost of orthognathic surgery include individual differences, hospital tier, and regional factors.

Reference information on different orthognathic surgical procedures and their associated costs:

Comparison Item/Procedure	Le Fort I Osteotomy of the Maxilla	Bilateral Sagittal Split Osteotomy (BSSO) of the Mandible	Bimaxillary Surgery
Reference Price	30,000–60,000 RMB per procedure	40,000–80,000 RMB per procedure	60,000–100,000 RMB per procedure
Principle of Procedure	A horizontal incision is made above the maxillary dental arch inside the mouth, followed by osteotomy along the Le Fort I fracture line. The bone segments are repositioned after osteotomy to correct developmental abnormalities.	Incisions are made on both the medial and lateral sides of the mandibular ramus to split the mandible sagittally, allowing adjustment of the mandibular position.	Bimaxillary surgery combines procedures on both the maxilla and mandible, performing simultaneous osteotomies and positional adjustments on both upper and lower jaws.
Target Population	Suitable for individuals with maxillary overdevelopment or underdevelopment	Suitable for individuals with abnormal mandibular development	Suitable for individuals with severe dentofacial deformities
Recovery Period	3–6 months	3–6 months	6–12 months
Duration of Effect	Long-term	Long-term	Long-term
Potential Risks	1. Bleeding and hematoma 2. Malocclusion	1. Nerve injury 2. Risk of fracture	1. Airway obstruction 2. Occlusal disturbances

Analysis of Influencing Factors:

1. Individual Differences: More complex cases of dentofacial deformity—such as significant skeletal asymmetry or multiple malocclusions—increase surgical difficulty and thus lead to higher costs.

2. Hospital Tier: Large hospitals or specialized oral and maxillofacial plastic surgery centers typically charge more due to advanced medical facilities and highly trained medical teams.

3. Regional Factors: In economically developed cities, where medical resources are abundant and surgeons possess higher technical expertise and experience, orthognathic surgery tends to be more expensive.

Prior to orthognathic surgery, patients should visit a reputable hospital for detailed oral imaging and consult with a qualified surgeon to determine the most appropriate surgical approach. After surgery, patients should wear prescribed orthodontic appliances as directed to stabilize surgical outcomes and maintain good oral hygiene to minimize infection risk.

Is it expensive for pregnant women to receive lung maturation shots?

The cost of antenatal corticosteroid injections (commonly known as "lung-promoting shots") for pregnant women is not particularly high, falling within a moderate price range for medical interventions. The cost for a single course of treatment typically ranges from several hundred to around 1,000 RMB, varying slightly depending on the region and hospital level. If there is a risk of preterm birth during pregnancy, timely medical evaluation is recommended, followed by standardized treatment under medical guidance. The key medication in these injections is corticosteroids.
