What is the difference of the incidence in clinical Frey syndrome in studies comparing classical parotidectomy with parotidectomy with superficial musculoaponeurotic system (SMAS) flap elevation and suturing?
Background: Although treatment of established Frey syndrome with botulinum toxin is effective and well accepted, prevention seems a better alternative. Prevention techniques have all involved some form of barrier between the parotidectomy bed and the skin, but there is a lack of conclusive evidence for the role of superficial musculoaponeurotic system SMAS flaps.
