Editor's Notes
- Hypergeusia is a taste disorder where the sense is abnormally heightened.[1][2] It can be associated with a lesion of the posterior fossa and Addison's Disease; where a patient will crave for salty and sour taste due to the abnormal loss of ions with urine.[3]
- ** Sometimes injery to the chorda tympani can be due to postoperative edema.. ** Bell's palsy is a type of facial paralysis that results in an inability to control the facial muscles on the affected side.[1]Symptoms can vary from mild to severe. They may include muscle twitching, weakness, or total loss of the ability to move one or rarely both sides of the face. Other symptoms include drooping of the eyelid, a change in taste, pain around the ear, and increased sensitivity to sound. Typically symptoms come on over 48 hours.[1]
