Discuss specific challenges encountered in the administration of local anesthesia in oral maxillofacial practice settings
What will be an ideal response?
Specific challenges encountered in OMFS local anesthesia administration include safe management of patients of all ages with diverse medical backgrounds who may require extensive treatment (e.g. full mouth extractions). Minor to life-threatening infections may be encountered. Achieving adequate local anesthesia in the presence of these infections while limiting the potential for needle tract infections (infections spread along needle pathways) and compensating for anatomic difficulties (with associated trismus and airway patency concerns) are serious and significant challenges encountered by OMF surgeons.
