Kligerman MP, Jin M, Ayoub N, et al. - In this decision analytical model, researchers sought to compare parotidectomy with observation for the management of pleomorphic adenoma in patients 50 years or older by age. This investigation was conducted from November 21, 2019, to June 15, 2020, using a Markov model. At 92 years of age for patients with superficial lobe tumors and at 85 years of age for patients with deep lobe tumors, an observation was more beneficial than surgery. No significant difference was found in outcomes between parotidectomy and observation among patients aged 70 to 80 years. Findings suggest that the outcomes associated with parotidectomy and observation among patients with pleomorphic adenoma are similar at 70 years of age or older and that observation in that age group may be a favorable treatment.
