Superior pharyngeal constrictor3/31/2023 ![]() ![]() So, Frey's syndrome is not limited to parotid surgery with injury to auriculotemporal nerve. The frey's syndrome is likely due to injury to auriculotemporal nerve with faulty regeneration, therefore Frey's syndrome is also known as Auriculotemporal syndrome.Ī variant of Frey's syndrome in which there is gustatory facial flushing but not sweating, occurs following facial paralysis due to faulty regeneration following injury to the facial nerve. These sympathetic fibres are to the sweat glands of the skin in the dissected field. The variations of the course of the external branch and the points of piercing the cricothyroid muscle or inferior constrictor pharyngeal muscle were evaluated. Discussion: Although safe approaches have been described for nerve protection during neck surgeries, it can expose injuries during preliminary surgery approaches as the nerve is thinner. The pharyngeal raphe is a midline tendinous seam where the constrictor muscles meet. Gross tumor volume is determined on the basis of CT findings in the lung and soft-tissue window. Target Volume Concept and Motion Management Strategy. The likely pathophysiology is aberrant regeneration of postganglionic secretomotor parasympathetic nerve fibres (originating from the otic ganglion) misdirected through several axonal sheaths of post- ganglionic sympathetic fibres feeding the sweat glands. The pharyngeal constrictors have a strong internal fascial lining called the pharyngobasilar fascia, and a thin external fascial lining called the buccopharyngeal fascia which, as we mentioned before, blends inferiorly with the pretracheal layer of deep cervical fascia. The variations of the course of the external branch and the points of piercing the cricothyroid muscle or inferior constrictor pharyngeal muscle were evaluated. Nisha Ohri, in IASLC Thoracic Oncology (Second Edition), 2018. The symptoms usually occur several months or even years after parotid surgery. Gustatory sweating or Frey's syndrome involves post-parotidectomy facial sweating and skin flushing while eating. is 'a' i.e., Post traumatic nerve fibres of facial nerve with parasympathetic of auriculotemporal nerve
