Oral SurgeryLe Fort III fractures are characterized by a fracture pattern that involves the separation of the facial skeleton from the cranial base. This type of fracture typically extends across the orbits and involves the zygomatic arches, leading to significant facial disfigurement and potential complications.

Oral SurgeryIn a grand mal epileptic patient requiring emergency extraction, it is essential to proceed with caution and ensure that the patient is on a stable anticonvulsive medication regimen. The patient should be monitored closely and have immediate access to medical support in case of a seizure during the procedure.

Oral SurgeryWith PT of 21 seconds (control 15 seconds), the PT ratio is 1.4, which is within acceptable limits for minor oral surgery. The treatment should proceed with extraction using sutures and local hemostatic agents for bleeding control. Vitamin K injection would reverse anticoagulation and potentially expose the patient to thromboembolic risk unnecessarily.

Oral SurgerySalivary gland stones, or sialoliths (calcified nodules), are most commonly found in the submandibular gland ducts (Wharton's ducts). This is due to several factors: the submandibular gland's saliva is more alkaline, has a higher concentration of calcium and phosphate, and the duct itself is longer and has a more complex, upward course, all of which contribute to the precipitation of salts and stone formation.

Oral SurgeryWhen the mandible is fractured bilaterally in the canine region, the central fractured segment loses the anterior pull from the muscles attached to it. The geniohyoid, genioglossus, and anterior belly of the digastric muscles are all attached to this segment and pull it posteriorly and inferiorly.

The Campbell line is an important anatomical reference line
used in radiology, particularly in the context of the occipitomental
view (also known as the Water's view). This line is drawn from the
outer canthus of the eye to the midpoint of the maxillary sinus and is used to
assess the position of the maxillary sinuses and other related structures in the
skull. Occipitomental view: This view is commonly used in
maxillofacial imaging to visualize the maxillary sinuses, orbits, and nasal
cavity. The Campbell line helps in evaluating the relationship of these
structures. Transpharyngeal view: This view is used to visualize the
pharynx Transorbital view: This view focuses on the orbits and
surrounding structures Towne view: This view is used to visualize the occipital
bone and the base of the skull

Oral SurgeryAlpha adrenergic agonists are used in combination with local anaesthetics to increase the concentration of LA at receptor site.

Oral SurgeryIn multiple extractions, maxillary teeth are extracted before mandibular, and posterior teeth before anterior. This sequence prevents blood and debris from falling into lower extraction sites, and extracting posterior teeth first provides better access and reduces tissue trauma.
