Long-term effects of parotidectomy

The present study investigated the long-term complications of parotidectomy, the differences in these complications in regard to the pathological diagnosis and type of surgery. The patients were questioned regarding the presence of facial paresis-paralysis, pain, loss of sensation, scarring, collapse, and mouth dryness in the area of operation. Complaints of pain (p = 0.287), scarring (p = 0.456), and mouth dryness (p = 0.136) did not show statistically significant differences between the cases with benign or malignant pathological outcomes. However, complaints of loss of sensation (p < 0.001), collapse in the area of operation (p = 0.025), paresis-paralysis (p < 0.001), and fear of repeated surgery (p = 0.032) were present at significantly higher rates. Complaints of pain (p = 0.258), scarring (p = 0.665), mouth dryness (p = 0.113) and fear of repeated surgery (p = 0.053) did not show statistically significant differences between the cases who underwent superficial or total parotidectomy. However, complaints of loss of sensation (p = 0.002), paresis (p < 0.001), and collapse in the area of operation (p = 0.019) were present at significantly higher rates. The type of tumor and surgical approach significantly affect the quality of life; however, parotidectomy generally does not lead to serious long-term complications that would disturb the patients.
