Excision of parotid tumor or parotid gland; lateral lobe, with dissection and preservation of facial nerve

AI EXPLANATION: This surgical procedure removes a tumor or abnormal growth from the outer portion (lateral lobe) of the parotid gland, which is the largest salivary gland located just in front of and below the ear. During the operation, the surgeon carefully identifies, dissects, and preserves the facial nerve that controls facial movement, protecting nerve function while taking out the affected tissue.
