Background
•Neoplasms of the parotid glands account for about 2-3% of head and neck tumors.
•Most tumors are benign and treatment is suprafacial parotidectomy
Lin et al. / American Journal of Otolaryngology–Head and Neck Medicine and Surgery 29 (2008) 94–100
IPRAS 2013
Background
•The surgical technique of
superficial parotidectomy via a
facelift incision is described.
Lohuis PJ et al .Ann Otol Rhinol Laryngol. 2009 Apr;118(4):276-80.

Aim
•To present the results of treatment, histology, complications and recurrence.
•To compare classic superficial parotidectomy with partial superficial parotidectomy.
IPRAS 2013
Method
•Retrospective analysis of all patients
with benign parotid tumors who
underwent parotidectomy at our
center between 2001 and 2010.
•The patients with malignant tumor
was excluded.
IPRAS 2013
Method
•Medical record review
•Clinical evaluation

MethodSurgical Technique for partial
suprafacial parotidectomy via a facelift incision
IPRAS 2013
• Incision is made behind the tragus.
• Then extended distally around the origin of the earlobe to the retroauricular fold.
• At the level of the tragus the retroauricular incision is extended posteriorly and then curved in occipital direction into o just below the hairline.
Results
•The series consisted of 75 patients, 49 women.
•The average age was 46 years (range 17-77 years).

Comparative analysis: Suprafacial vs parcial
IPRAS 2013
Discussion
•The application of techniques based on the anatomy of the facial nerve and less invasive surgeries such as partial suprafacial parotidectomy allow low morbidity rates and no difference in recurrence rate.
•The results obtained were similar to those described in the literature.
