Basic Surgical Technique Flashcards
Stages of surgery (10)
- Consent
- Safety checklist
- Anaesthesia
- Access
- Bone removal as necessary
- Debridement/wound management
- Suture
- Achieve haemostasis
- Post op instructions + meds
- Follow up
When must we obtain written consent?
When tx involves conscious sedation or GA
how do we obtain surgical access?
Lifting a mucoperiosteal flap
What sits between the bone and the gum?
Periosteum
Why do we want a wide-based incision?
To allow the flap to maintain good circulation
What makes up a 3 sided flap?
- Distal relieving incision
- Crevicular incision around tooth
- Mesial relieving incision between 7 and 8
How should we position our distal relieving incision?
Bit more buccal so we dont damage lingual nerve
Follow the external oblique ridge of the mandible
What makes up an envelope flap? (2)
- Distal relieving incision
- Crevicular incision along gingival crevice
- Extends midway along 7 or further
What instruments are used for soft tissue retraction (3)
- Ash
- Rake retractor
- Howarths periosteal elevator
Function of ash
Protecting and retracting lingual soft tissues
Function of rake retractor and howarths periosteal
Reflects light in and protects soft tissues/adjacent structures like nerves
Compare rake retractor to howarths periosteal
HOWARTHS - narrow + thinner
RAKE - reflects light + protects soft tissues
Why do we use electrical straight handpieces for bone removal instead of air driven?
Air driven may lead to surgical emphysema
- driving air or gas underneath mucosa or skin
- can lead to hospital admission
What major structures must we be wary of when using an elevator?
- Antrum - max sinus
- ID canal
- Mental nerve
Whats the exception for using the adjacent tooth as a fulcrum ?
Only if its to be extracted too
