Description
Estimated cost for Lateral sinus floor elevation at general public hospitals in China is about ¥5600-20000, and at Grade 3A hospitals about ¥8000-25000, varying by hospital tier and region.
Main Uses
Primary clinical use is to augment posterior maxillary alveolar ridge height for dental implant placement in patients with severe sinus pneumatization and inadequate native bone (<4–5 mm). Indications include: edentulous posterior maxilla, failed previous implants due to insufficient bone, and cases where internal (crestal) sinus lift is contraindicated due to extreme bone deficiency (<3 mm) or compromised sinus anatomy.
Normal Range
Upper sinus external lift (sinus floor elevation) is a surgical procedure, not a diagnostic laboratory test; therefore, it has no numerical 'normal range' or quantitative biomarkers. Clinical success is assessed radiographically (e.g., postoperative CBCT showing ≥5–7 mm of grafted bone height, absence of membrane perforation, stable implant integration) and clinically (e.g., absence of infection, pain, or sinusitis within 6–12 months).
Low Values - Possible Causes
Low graft volume or insufficient bone height post-surgery may result from: 1) Intraoperative Schneiderian membrane perforation, 2) Early graft resorption due to infection or poor vascularization, 3) Inadequate primary stability of the graft material, 4) Patient-related factors such as uncontrolled diabetes or smoking, 5) Premature loading or mechanical failure before osseointegration.
High Values - Possible Causes
Excessively high or abnormal graft elevation is rare but may be associated with: 1) Overpacking of graft material causing sinus membrane overdistension or hematoma, 2) Unintended violation of the sinus roof or orbital floor, 3) Postoperative hemorrhage or seroma leading to exaggerated radiographic opacity, 4) Graft material migration into the sinus cavity, 5) Iatrogenic sinusitis or mucocele formation mimicking excessive elevation on imaging.
