1
Q

Blinded techniques for inferior alveolar nerve blocks & success rates (prev study)

A

intraoral (100%), angled (73%)& vertical (59%)

2
Q

Study- assessment by CT & dissection success rates for extraoral US-guided IA block

A

Assessment by CT and dissection determined success rates of 81.3% and 68.8%, respectively; 68.8% of injections had inadvertent methylene blue dye staining of the lingual nerve.

3
Q

Take-homes

A

Technique with US was no more accurate than blinded techniques.
Any extraoral approach to the IAN is likely to also desensitize the lingual nerve.
