It occurs due to various factors including direct intraoperative injury, traction, thermal injury, ischemia, and anatomical variations. While most cases occur immediately after surgery, some may develop within the first 24 to 72 hours due to postoperative edema or hematoma. Delayed facial nerve paralysis occurring more than 72 hours after surgery is extremely rare. We report a case of a 60-year-old woman who developed delayed facial nerve palsy 16 days after parotid gland surgery. Mild paralysis of the lower lip was observed postoperatively, but no abnormalities were detected in other facial muscles. The postoperative course was uneventful, and the patient was discharged on the eighth day. However, on the 10th day after the surgery, pain appeared around her ear, and severe facial nerve paralysis developed on the 16th day. Pain was present from the ear to the scalp of the temporal region, but no objective findings such as postoperative infection, edema, hematoma, or tumor recurrence were observed. The patient received combined therapy with steroids and antiviral agents based on the treatment for idiopathic facial nerve palsy, and the paralysis fully recovered after four months. Delayed facial nerve palsy following parotid gland tumor surgery is extremely rare, and it is important to investigate causative factors before initiating treatment.  \nCategories: Neurology, Otolaryngology  \nKeywords: benign parotid gland tumor, delayed facial nerve palsy, parotid gland surgery, salivary gland tumor, varicella-zoster virus  \nIntroduction  \nIn parotid gland tumor surgery, we must pay attention to complications such as facial nerve palsy, postoperative hematoma, salivary fistula, and Frey 's syndrome, in addition to achieving pathological control of the tumor. The incidence of facial nerve palsy after parotidectomy is reported to be approximately 23-38% for temporary palsy and 5-13% for permanent palsy, with the permanent palsy rate being as low as 1.6% when limited to benign tumors [1] . Facial nerve palsy typically presents immediately following surgery. However, it may also manifest within the first 24-72 hours postoperatively, most commonly secondary to hematoma or edema. In contrast, delayed facial nerve palsy (DFNP) occurring more than 72 hours after surgery is exceedingly rare [2] . We encountered a case where severe facial nerve palsy appeared more than two weeks after surgery. Although delayed postoperative facial nerve palsy is predominantly reported following middle ear or temporal bone surgery, cases occurring after parotid gland tumor resection have also been documented. This report emphasizes the importance of understanding delayed paralysis following parotid surgery and the significance of early therapeutic intervention.  \nCase Presentation  \nA 50-year-old woman in good health was referred to our department complaining of a tumor in front of her right ear that had been present for over a year. She had no medical history other than a cesarean section and had never had shingles. The physical examination revealed a movable, elastic, hard mass measuring approximately 15 mm in front of","cbCaivu95tQlw1Ny","https://ap.wps.com/l/cbCaivu95tQlw1Ny","pdf",2243709,"English","# Abstract\n## Introduction\n## Case Presentation","[{\"question\":\"How soon after parotid tumor surgery did the facial nerve palsy develop in this case?\",\"answer\":\"The patient developed delayed facial nerve palsy 16 days after parotid gland surgery.\"},{\"question\":\"What symptoms appeared around the time the paralysis progressed?\",\"answer\":\"Pain appeared around the ear, extending from the ear to the scalp of the temporal region, followed by severe facial nerve paralysis.\"},{\"question\":\"How was the delayed facial nerve palsy treated and what was the outcome?\",\"answer\":\"Combined therapy with steroids and antiviral agents was given, and full recovery was achieved after four months.\"}]","Delayed Facial Nerve Palsy Developing After Surgery for a Benign Parotid Gland Tumor | PDF",1790741588,15]
