Background: Surgical treatment of pleomorphic adenoma of the parotid gland remains a subject of major debate. The investigators compared postoperative complications and surgical parameters between modified partial superficial parotidectomy and conventional superficial parotidectomy.
Methods: Clinical records of 129 patients were reviewed and analyzed for clinical characteristics.
Results: Compared with the conventional superficial parotidectomy group, the modified partial superficial parotidectomy group had significantly lower rates of auricular numbness, Frey's syndrome, and obvious facial asymmetry (all P values <.05). The distance between the primary tumor capsule and satellite nodules ranged from .06 to 8.48 mm, and the greatest distance between the primary tumor capsule and satellite nodules was observed in tumors >4 cm. Furthermore, satellite nodules were more common in tumors >4 cm than in tumors <2 cm or tumors between 2 and 4 cm (all P values <.05).
Conclusions: Modified partial superficial parotidectomy compares favorably surgically and clinically with conventional superficial parotidectomy in certain patients.

Nerve dissection technique for excision of parotid tumors: Outcomes controlling for tumor size and location.
Am J Otolaryngol

Department of Otolaryngology - Head & Neck Surgery, University of Michigan, Ann Arbor, MI, USA. Electronic address:
Purpose: We examined operative efficiency, rate of facial nerve paresis, and post-operative outcomes in patients undergoing retrograde (RGD) vs anterograde dissection (AGD) of the facial nerve controlling for tumor location.
Methods: Single-institution, retrospective analysis of patients with benign parotid tumors undergoing superficial parotidectomy with facial nerve dissection over a six-year period. Operative and pathology reports were reviewed to classify tumor size, location in relation to facial nerve branches, and technique for facial nerve dissection.

The modified Blair incision is commonly used for superficial and deep lobe lesions of the parotid gland. The most common complication of the parotidectomy procedure is the postoperative surgical scar. Epidermos barrier cream is a type of cream that helps in wound healing by covering the wound.

Venous vascular malformations of the parotid gland are very rare vascular tumors, especially among adults. This case report discusses the presentation and challenges of diagnosing a venous vascular malformation of the parotid gland in a patient with previous oncologic history. Our patient is a 45-year-old female with a history of breast cancer, meningioma, and secreting pituitary adenoma who presented with a malformation on magnetic resonance imaging, incidentally demonstrating a T2 intense mass in the superficial lobe of the right parotid gland.

Department of Otolaryngology-Head and Neck Surgery, Mayo Clinic, Rochester, Minnesota, USA.
Objective: The extent of parotidectomy for benign tumors has de-escalated in the United States. We aim to define modern benchmarks for operative time and hospital length of stay (LOS) in parotidectomy and identify risk factors that may prolong these benchmarks.
Study Design: This is a retrospective cross-sectional study of all adults who underwent parotidectomy for a primary parotid neoplasm between January 2011 and December 2021 using the American College of Surgeons National Surgical Quality Improvement Program database.
