Oral And Maxillofacial Surgery

Surgical Considerations for the Submandibular and Parotid Glands When performing surgery on the submandibular and parotid glands, it is crucial to be aware of the anatomical structures and nerves at risk to minimize complications. Below is an overview of the key nerves and anatomical landmarks relevant to these surgical procedures. Major Nerves at Risk During Submandibular Gland Surgery Hypoglossal Nerve (CN XII): This nerve is responsible for m…

Latency period: Adults: 5 – 7 days Infants (8 months): 0 – 2 days Consolidation phase: Time between traction cessation & device removal Transport DO: Trailing edge: Bone formation Leading edge: Cartilage formation Midface distraction age: ≥3.5 years SARPE indication: Transverse expansion > 5 mm…

Periodontal Surgery Preferred: Vicryl, PDS-II for buried sutures Surface: Silk or nylon for easy removal Size: 4-0 to 6-0 Extraction Sites Simple extractions: Often no sutures needed Surgical extractions: 3-0 or 4-0 silk or Vicryl Alveolar bone contouring: Resorbable sutures preferred Implant Surgery Flap closure: Non-absorbable for precise control Healing abutment placement: Absorbable around healing caps Size: 4-0 to 5-0 Oral Pa…

Osteogenesis in Oral Surgery Osteogenesis refers to the process of bone formation, which is crucial in various aspects of oral and maxillofacial surgery. This process is particularly important in procedures such as dental implant placement, bone grafting, and the treatment of bone defects or deformities. Mechanisms of Osteogenesis Osteogenesis occurs through two primary processes: Intramembranous Ossification: This process involves the di…

Bone Healing: Primary vs. Secondary Intention Bone healing is a complex biological process that can occur through different mechanisms, primarily classified into primary healing and secondary healing (or healing by secondary intention). Understanding these processes is crucial for effective management of fractures and optimizing recovery. Secondary Healing (Callus Formation) Secondary healing is characterized by the formation …
