From the Research
The most common complication after parotidectomy is Frey's syndrome, as supported by the most recent and highest quality study available 1.
Complications of Parotidectomy
The complications of parotidectomy can be significant and impact the patient's quality of life.
- Frey's syndrome, also known as gustatory sweating, is a common complication after parotidectomy, with a reported incidence of up to 30-40% of patients 1.
- Facial nerve weakness or paralysis is another potential complication, but it is less common than Frey's syndrome, affecting approximately 1-3% of patients permanently 2.
- Other less frequent complications include hematoma, infection, salivary fistula, and numbness around the ear due to greater auricular nerve injury.
Management of Complications
Management of these complications is crucial to improve patient outcomes and quality of life.
- Frey's syndrome can be managed with botulinum toxin injections, which have been shown to be effective in reducing symptoms 3, 4.
- Facial nerve weakness or paralysis can be managed with eye protection, facial exercises, and physical therapy, with most patients experiencing complete recovery within 6-12 months 2.
- Other complications, such as hematoma and infection, can be managed with standard medical and surgical interventions.
Prevention of Complications
Prevention of complications is also important to consider.
- The use of a sternocleidomastoideus flap during parotidectomy has been shown to not significantly reduce the incidence of Frey's syndrome 5.
- However, other preventive measures, such as the use of acellular dermal matrix or dermofat grafts, may be effective in reducing the incidence of Frey's syndrome, especially in high-risk patients 1.
