Local anaesthesia with conscious sedation in parotid gland tumour resection: a retrospective review.

Objectives: This study explored the suitability of local anaesthesia with conscious sedation for parotid gland tumour surgery.

Methods: Three hundred sixty-four medical records were reviewed to gather data on several key aspects for retrospective analysis. These included age, incision length, operation time, tumour size, NNIS score, ASA score, and pathology. Additionally, we documented postoperative complications.

Results: A total of 111 patients underwent surgery under local anaesthesia with conscious sedation, while 253 patients underwent surgery under general anaesthesia. We found significant differences in surgical time, incision length, tumour location and tumour size between the two groups. There was no difference in postoperative complications or age.

Conclusions: Performing parotid gland tumour resection under local anaesthesia with conscious sedation is feasible. Compared with general anaesthesia, this approach does not increase the risk of complications or surgical trauma and can reduce the risk of anaesthesia-related complications. This is beneficial for expanding surgical treatment indications, allowing some patients who cannot tolerate general anaesthesia to also receive treatment.
