Purposes: The aim of this study was to find out the frequency of the
functional outcomes related to the superficial & conservative total parotidectomy.
Background: Functional outcomes especially facial nerve injury & Frey's
syndrome during the parotid surgery represent annoying problem; as it is
associated with cosmetic problems & multiple physician visits; "to minimize this
outcomes" remains in question.
Patients and methods: The study included 52 patients; 6(11.5%) <35 years
old, 28 (53.8%) between 35-50 years old and 18 (34.7%) above 50 years old. All
patients underwent clinical evaluation, laboratory assessment, U/S, CT scan &
MM examination. All patients undergoing either superficial or conservative total
parotidectomy.
Results: In this study; immediately postoperative; facial nerve injury was
observed in 20 patients; in this series, 14 (70%) developed temporary facial palsy,
whereas 6 (30%) developed permanent facial paralysis. Cervical branch was t1"1
most commonly injured nerve 8 (40%). Symptomatic Frey's syndrome, was
observed in 5 (9.6%) & Parotid leak was observed in 11 (27.5%); all were
observed in superficial parotidectomy; as sialocele in 5 (12.5%) or fistula;
glandular 4 (10%) or ductal 2 (5%).
Conclusions: Facial nerve injury is more common in total conservative
parotidectomy than in superficial parotidectomy. Early detection of nerve injury, is
quite helpful to reduce the facial deformity by early reconstruction and other
procedures. But Parotid leak only is observed in superficial parotidectomy; most of
this leak can be managed conservatively except ductal fistula. Symptomatic Frey's
syndrome is more common in superficial parotidectomy |
