Abstract
Dissecting deep to the superficial musculoaponeurotic system, SMAS, a popular option for facelifts, has the potential for injury to the parotid gland leading to post operative sialoceles and fistulas. Similarly, deep plane procedures in the neck which include partial submandibular gland resection may lead to salivary gland leaks. We previously described the management of sialocele following rhytidectomy.1 Since then, administration of Botulinum toxin A has emerged as the primary treatment and prevention of this rare complication. The technique of administration and dosage of botulinum toxin in the treatment algorithm is not well-defined. We present a literature review and our current protocol of the most efficacious injection technique and dosing to prevent and treat injury to the parotid and submandibular glands.
