  • 1. PARTIAL SUPERFICIAL PAROTIDECTOMY IN PAROTID BENIGN TUMOR Ricardo Yáñez MD, Francisco J. Loyola MD, Jorge Cornejo MD, Mariana Valenzuela MD, Raúl Martínez MD and Grace Tapia MD. Dr. Sotero del Río Hospital Chile IPRAS 2013
  • 2. 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
  • 3. 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. IPRAS 2013
  • 4. Aim • To present the results of treatment, histology, complications and recurrence. • To compare classic superficial parotidectomy with partial superficial parotidectomy. IPRAS 2013
  • 5. 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
  • 6. Method • Medical record review • Clinical evaluation • t-student (SPSS 16.0) IPRAS 2013
  • 7. Method Surgical Technique IPRAS 2013
  • 8. Method Surgical 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.
  • 9. Results • The series consisted of 75 patients, 49 women. • The average age was 46 years (range 17-77 years). IPRAS 2013
  • 10. Results Distribution by surgical technique IPRAS 2013

  • 15. 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.
