Principles of general management and treatment of the salivary glands
Two forms are employed. Superficial parotidectomy involves removing the parotid tissue superficial to the facial nerve. Total parotidectomy involves dissecting the facial nerve and its branches off the deep lobe and removing the deep lobe. Any parotid surgery is therefore a dissection of the facial nerve and its branches. To remove the deep lobe, the whole facial nerve from the main trunk to the divisions of the upper and lower main branches has to be carefully dissected on its deep surface so that it can be lifted upwards to allow the deep lobe to be removed by blunt dissection from the pharyngeal space.
