There is a 25-50% risk of facial weakness directly after parotidectomy and a 1-2% risk of permanent weakness. [4] Frey’s syndrome may occur in up to 90% of patients. [4] Risk of mortality is very low in reference to the surgery. [4] In a case of benign tumor, such as pleomorphic adenoma, a significant outcome is also the rate of tumor recurrence.
They are a relatively common complication following surgery to the salivary glands, [4] commonly parotidectomy (removal of the parotid gland). [5] In this case the sialocele is the result of saliva draining out of remaining parotid tissue, and occurs about 5 to 10% of cases of superficial (partial) parotidectomy. [5] [6]
After a parotidectomy, the nerves from the Auriculotemporal Nerve that previously innervated the parotid gland can reattach to the sweat glands in the same region. The result is sweating along the cheek with the consumption of foods (Frey's syndrome). Treatment involves the application of an antiperspirant or glycopyrrolate to the cheek ...
Surgical techniques in parotid surgery have evolved in the last years with the use of neuromonitoring of the facial nerve and have become safer and less invasive. [19] After surgical removal of the parotid gland (parotidectomy), the auriculotemporal nerve is liable to damage and upon recovery it fuses with sweat glands. This can cause sweating ...
30–50% (after parotidectomy) Frey's syndrome (also known as Baillarger's syndrome , Dupuy's syndrome , auriculotemporal syndrome , [ 1 ] or Frey-Baillarger syndrome ) is a rare neurological disorder resulting from damage to or near the parotid glands responsible for making saliva , and from damage to the auriculotemporal nerve often from surgery.
Treatment of individual infections may prevent injury to the gland parenchyma. In the past, the disease was treated with aggressive surgical interventions such as Stensen’s duct ligation, superficial or total parotidectomy, and tympanic neurectomy. Nowadays, the disease is managed with sialendoscopic procedure.
The most common applications are in spinal surgery; selected brain surgeries; carotid endarterectomy; ENT procedures such as acoustic neuroma (vestibular schwannoma) resection, parotidectomy; and nerve surgery. Motor evoked potentials have also been used in surgery for thoracic aortic aneurysm. Intraoperative monitoring is used to :
The second leading cause of salivary obstruction is from strictures and adhesions, which can happen from prior salivary gland infections, including childhood infections like mumps. Most strictures could be seen in the parotid duct and mostly in the disease process of chronic recurrent sialadenitis. [citation needed]
