Taking the shooting pain away
Dr. Liyanage explains that the clinical presentation is sensitivity in the “trigger-zones” which is a small area of the face, where a light touch can set off the pain.
The trigger zones are around the mouth and the chin and just beyond the brow.
The criteria for diagnosis of TN are:
- Paroxysmal attack of pain, lasting seconds to about two minutes, with or without the presence of aching in-between.
- The pain being intense, sharp and stabbing and superficial.
“We take down the history and perform a thorough intraoral examination which includes orthodontic (by referring to a Dental Surgeon) and non-orthodontic examinations,” he says, adding that there is also meticulous examination of the cranial nerves 5, 7 and 8, with the doctors ordering a CT scan and MRI to exclude growths adjacent to the trigeminal nerve.
- Cranial nerve 5 – sensation, corneal reflex and ability to chew will be checked.
- Cranial nerve 7 – musculature of face will be checked by closure of eye, taking mouth to a side and getting the person to blow out air.
Cranial nerve 8 – hearing will be checked.
For Mr. Patrick there is no more pain and there is no carrying of tablets around. Nearly four years ago, on October 23, 2014 he underwent microvascular decompression.
“Devi kenek wage,” is his compliment to Dr. Liyanage for dispelling the pain and the grimacing and paving the way for him to smile again.
