Oral Surgery: Course Part 1




Oral Surgery: Course Part 1

                                                        Cranial nerves

Twelve nerve pairs, called cranial nerves, project from the brain.

Each nerve has a specific name and is designated by a Roman numeral.

                                            Names of cranial nerves

1. Olfactory nerve

2. Optic nerve

3. Oculomotor nerve

4. Trochlear nerve

5. Trigeminal nerve

6. Abducent nerve

7. Facial nerve

8. Vestibulocochlear nerve

9. Glossopharyngeal nerve

10. Vagus nerve

11. Accessory nerve

12. Hypoglossal nerve

                                                              Classification of cranial nerves

Sensory cranial nerves: contain only afferent (sensory) fibers

              1- Olfactory nerve

              2- Optic nerve

              8- Vestibulocochlear nerve

Motor cranial nerves: contain only efferent (motor) fibers

             3- Oculomotor nerve

             4- Trochlear nerve

             6- Abducent nerve

             11- Accessory nerve

             12- Hypoglossal nerve

Mixed nerves: contain both sensory and motor fibers---

             5- Trigeminal nerve,

             7- Facial nerve,

             9- Glossopharyngeal nerve

             10- Vagus nerve

                                                                  local Complications Due to solution

1- infection


2- local tissue irritation


3- pain on injection


                                                                local Complications Due to Needle insertions

1- pain on injection.

2- Needle breakage.

3- infection.

4- edema .

5- hematoma.

6- trismus.

7- facial nerve paralysis.

8- soft tissue injury ‘’ sloughing of issue “.

9- post-anesthetic intra-oral lesions.

10- prolonged anesthesia or paresthesia .


                                                                 systemic Complications in Local Anesthesia

1- Over-dose

2- Epinephrine over-dose

3- Allergy

4- idiosyncrasy

5- fainting “vasovagal attack, syncope ” 

                                                                                                                                    Causes

        Vasovagal syncope occurs when the part of your nervous system that regulates heart rate and blood pressure malfunctions in response to a   

       trigger, such as the sight of blood.


       Your heart rate slows, and the blood vessels in your legs widen (dilate.)

       This allows blood to pool in your legs, which lowers your blood pressure.

       Combined, the drop in blood pressure and slowed heart rate quickly reduce blood flow to your brain, and you faint.
       
Sometimes there is no classical vasovagal syncope trigger, but common triggers include:
