OBJECTIVES: This study aimed to evaluate sensory dysfunction resulting from great auricular nerve (GAN) sacrifice versus preservation in parotid surgery for benign lesions and its imact on long-term health-related quality of life (QOL). DESIGN: Retrospective. SETTING/MAIN OUTCOME MEASURES: Participants were divided into two groups (GAN and non-GAN), and both short-term (two postoperative weeks) and long-term (at least 5 years) QOL were assessed. The second item of the Parotidectomy Outcome Inventory-8 (POI-8) was used to analyse postoperative sensory loss. All items of the POI-8 questionnaire were used to determine health-related QOL.We used t test for dependent samples and Mann-Whitney U-test to compare patient groups PARTICIPANTS: A total of 137 patients (65 male and 72 female) enrolled in this study. Average age at the time of surgery was 53 years (±12.8). RESULTS: The GAN preservation group had significantly better sensation than the GAN sacrifice in short term (2.8 vs 2.1; P = 0.017). Both groups experienced improved sensation in the long term, and there was a trend towards better QOL in the GAN-preservation group. However, the difference in sensation was not statistically significant (1.7 vs 1.3; P = 0.145). Health-related QOL also increased in the long term (compared to short term) for both groups (7.6 ± 6.2 to 12 ± 7.6; P < 0.0001) postoperatively. GAN preservation did not significantly improve sensation in long term, nor did it increase health-related QOL postoperatively. CONCLUSION: Although GAN preservation was easily feasible, it only improved sensation in short term. We report a negative result: GAN preservation did not significantly improve sensation in long-term, nor did it increase health-related QOL postoperatively when compared to GAN sacrifice.
