Which is most frequently performed to correct a skeletal mandibular retrognathia
1) "C" type osteotomy
2) Horizontal osteotomy of the ramus
3) Oblique subcondylar
4) Sagittal split osteotomy of the ramus
Oral Surgery
Answer: 4
Skeletal mandibular retrognathia, characterized by a backward positioning of the mandible relative to the maxilla, is commonly corrected using a sagittal split osteotomy (SSO) of the ramus. This surgical procedure involves making a cut in the ramus of the mandible, allowing the surgeon to reposition the mandible forward. The SSO is favored because it provides good access, allows for significant advancement of the mandible, and has a relatively low complication rate. Other options, such as "C" type osteotomy or horizontal osteotomy of the ramus, are less commonly performed for this specific condition.

BEST explains the damage to his brain?

Which of the following is a congenital deficiency associated with a hemorrhagic diathesis?
1) Hageman trait
2) Parahemophilia
3) Hypoprothrombinemia due to liver disease
4) Hemophilia A
Hemophilia A is a congenital defect due to various abnormalities of the gene on the X chromosome that codes for factor VIII, leading to a hemorrhagic diathesis. Hageman trait is also congenital but does not directly cause a bleeding disorder.
A patient who is receiving anticoagulants requires extraction of a tooth. Laboratory data indicating prothrombin time is 21 seconds with a control time of 15 seconds. The treatment should consist of
1. Regulation of the anticoagulant level with heparin
2. Injection of vit K and immediate extraction
3. Injection of vit K and extraction after half an hour
4. Extraction of the tooth and use of sutures and local haemostatic agent
