Clinical outcome of parotidectomy with reconstruction: Experience of a regional head and neck cancer unit

Eyituoyo Okoturo, Anslem Osasuyi

Abstract


Background: Salivary gland pathologies represent a histologically diverse group of benign and malignant neoplasms. Currently, World Health Organization recognizes 13 benign and 24 malignant variants of all salivary gland neoplasms. Surgery continues to remain the main-stay for treatment of parotid gland neoplasms. The aim of this study was to document our experiences of the patients treated for parotid tumors and find out if any compelling variable predicted the relative clinical outcomes. Materials and Methods: This was a retrospective study, from records of parotidectomies performed at the operating theatre by the head and neck cancer division of the study institution between 2010 and 2013. Eligibility for study inclusion included cases with benign or malignant parotid neoplasms requiring surgical management with or without adjunct radiotherapy. The predictors of postoperative complications, overall survival (OS), and disease-free survival (DFS) were analyzed. Results: A total of 20 patients underwent parotidectomy. The mean age was 42 years. Tumors were located on the left parotid in 13 cases (65%) and the right parotid in 7 cases (35%). The surgical procedures comprised 16 superficial parotidectomies, 1 total parotidectomy, and 3 radical parotidectomy (inclusive of facial nerve sacrifice) and 2 neck dissections levels II–V. The reconstructive procedures were 2 facial nerve branch cable grafts, 1 end-to-end facial-facial nerve branch anastomoses, and 2 facial re-animation surgeries (temporalis muscle suspensions). A total of five cases (33.3%) had postoperative complications. 2 variables (length of surgery and neck dissection) were found to have an impact on postoperative complications that were statistically significant. Additionally, length of surgery was a significant predictor on the 2 years OS and DFS. Conclusion: The result of this study showed good clinical outcome, especially in the benign cases. The comprehensive clinical outcome of the malignant cases could not be objectively assessed, as the OS and DFS were 50% at 2-years follow-up. It is our submission that a larger sample size is utilized in subsequent studies and quality of life evaluation is included in the methodology.
