ABSTRACT: Background: Parotid surgery with dissection of the facial nerve
branches is a technically challenging surgery. Even in experienced hands, parotidectomy
has well-documented post-operative complications. We aim to evaluate complications
following parotid surgery. Methods: We retrospectively reviewed the
charts of 187 patients who underwent parotidectomy from January 2010 to January 2020 performed in surgical oncology department
South Egypt Cancer Institute, Assiut University, from patients (57.3% males and
42.7% females, average age 42.96 years). Results: 78.4% Patients had benign tumors,
the most frequent being pleomorphic adenoma 55.1% followed by Warthin’s tumour
16.9%, and 21.6% malignant tumors, mucoepidermoid carcinoma being the most
frequent. Superficial parotidectomy was the most common surgery 40.4% performed followed by 25.3%, total conservative
parotidectomy, while 1.1%, underwent radical
parotidectomy, (extended radical parotidectomy was performed 2.2%), and revision total parotidectomy (Recurrence 6.7%, and
parotidectomy with modified radical neck dissection (MRND) 7.9%. The most
common complication following parotidectomy was transient facial nerve palsy
21.3%. Permanent facial nerve paresis was observed in 3.9%, sensory deficit in
20.2%, sialocele in 6.7%, hematoma formation 3.4% and wound infection in 7.3%, and recurrence 7.3%. Frey’s syndrome occurred in 7.3% and salivary
fistula 5.1%. Conclusion: Parotidectomy is safe procedure causing minimal complications. Transient facial palsy is
the most common postoperative complication.
