Discuss possible complications of the tuberosity-approach maxillary nerve block
What will be an ideal response?
The tuberosity-approach maxillary nerve block injection has the highest risk of peri-injection hematoma formation, due to its proximity to the pterygoid plexus of veins and maxillary arteries. Possible risks with the greater palatine foramen approach include:
displacement of orbital structures, diplopia (anesthesia of the sixth cranial nerve), retrobulbar block (mydriasis, anesthesia of the cornea, ophthalmoplegia), optic nerve block (transient loss of vision in that eye is possible), penetration into the nasal cavity. Maxillary injection techniques are contraindicated in patients with clotting disorders or on anticoagulant therapy. Alternate techniques should be used in these instances.
