Likelihood

medium

A potentially serious complication, as infection can spread via the fascial planes of the neck. It can rarely affect the spaces in the floor of the mouth and cause Ludwig angina.

long term
high

A hypofunctional salivary gland can result in decreased saliva production and protection against acid erosion, leading to dental decay.

Following superficial parotidectomy, transient facial nerve palsy occurs in approximately one third to two-thirds of patients.[51][52][53][54] Cosmetic deformity is relatively minor, but recurrent symptoms may occur in up to 11% to 13%,[51][53] although not all require further treatment. A subtotal parotidectomy cosmetic defect is more marked and the risk to the facial nerve is probably slightly higher, although this has not been demonstrated.[54] The incidence of recurrent symptoms is possibly lower, <4%,[54] although fewer recurrences occurred with a superficial parotidectomy in this series. The extent of the disease and preferences of the patient will also influence the choice of surgical procedure. The pattern of facial weakness is likely to involve one or more nerve branches and is commonly panfacial,[51][52] because of widespread fibrosis within the gland. Recovery is typically over a 3- to 6-month period and usually complete. Permanent palsy occurs in <1%.[51][52][53][54] The incidence of hematoma, seroma, or significant infection should be <5%.[51][52]
