Cervical plexus block in the management of acute otitis externa and severe laryngeal pain post trauma

Evaluation of analgesic efficacy of superficial cervical plexus block in patients undergoing modified radical mastoidectomy: A randomised controlled trial

“…In this study, the technique used for performing ultrasound-guided SCPB anatomically corresponds to C4–C5 level and the end point was depositing local anaesthetic (LA) between the posterior surface of SCM muscle and prevertebral fascia. [ 5 10 11 ] Superficial and intermediate cervical plexus block showed a similar analgesic effect in patients undergoing carotid endarterectomy, rather intermediate was mentioned as part of superficial (intermediate) cervical plexus block. [ 12 ] The permeable nature of this prevertebral fascia can eventually affect the spread of LA to deeper tissues and can produce similar analgesic effects as deep cervical plexus block.…”

“…The rarely reported adverse effects are voice hoarseness and partial hemi-diaphragmatic paresis which require no active intervention and are self-limiting. [ 5 6 9 ]…”

“…Group ‘Block’ ( n = 15): Patients received ultrasound-guided SCPB with 5 mL of 0.5% ropivacaine. [ 5 9 10 ]…”

“…SCPB was effective in avoiding excessive opioid use and reduced discomfort during aural toilet. [ 5 ] The reported mechanism of SCPB is that it blocks the cutaneous supply to the ear and neck, motor supply to neck muscles and is known to have connections with the cranial nerve and sympathetic trunk via ansa cervicalis. [ 6 ] With encouraging results of ultrasound-guided SCPB, we planned the present randomised controlled trial (RCT) in patients undergoing modified radical mastoidectomy.…”
