Background and Objectives One of the common complications after parotidectomy is a decrease in skin sensation around the parotid gland. This is known to be associated with damage to the great auricular nerve (GAN). The purpose of this study was to investigate the pattern of tactile sensory recovery after parotidectomy and the difference in sensory recovery according to the preservation or sacrifice of the GAN. Subjects and Method Fifty-two patients who underwent parotidectomy were enrolled in this study. The Touch Test Sensory Evaluator was used to measure the minimum tactile threshold value at 6 sites around the auricle before surgery and at 1 week, 1, 3, 6 and 12 months after surgery. Results The tactile threshold was the highest at 1 month after parotidectomy in all 6 sites. After 1 month, the threshold value gradually decreased until 12 months after surgery. However, the threshold was not completely recovered to the preoperative threshold level. At least one branch and the main trunk of GAN were preserved in 39 patients; one of GAN branches was preserved but the main trunk of GAN was partially injured in 3 patients, and the main trunk of GAN was completely injured in 10 patients. The tactile sensory recovery showed no significant differences in relation to the GAN status. Conclusion The tactile sensory value kept decreasing up to one month following parotidectomy and then gradually recovered. However, the tactile sensory did not recover completely even one year after surgery. The GAN preservation did not affect tactile sensory recovery.
