Background: Fine needle aspiration (FNA) is a common diagnostic tool used in the initial evaluation of parotid masses. In the literature, variable diagnostic accuracy of FNA is reported. Therefore, when considering clinical management of these patients, the utility of FNA is unclear. The aim of this study was to determine the capability of ultrasound-guided FNA to differentiate between benign and malignant neoplasms. Further, the way in which FNA results affect clinical decision-making was assessed.
Methods: Retrospective data were collected for all patients who underwent parotidectomy at a large Canadian tertiary care center between 2011 and 2016. Patient demographics, preoperative imaging reports, preoperative FNA results, and final pathological diagnosis were analyzed.
Results: Of the 199 patients who underwent parotidectomy, 184 had preoperative ultrasound-guided FNA. There were a total of 13 non-diagnostic FNAs. In diagnosing malignancy, FNA had a sensitivity and specificity of 71.4% and 98.7%, respectively. The positive predictive value (PPV) was 83.3%. The negative predictive value was 97.5%. Of the non-diagnostic FNAs, 2 out of 13 (15.4%) were deemed malignant neoplasms on final pathology.
Conclusion: FNA is a useful adjunct in the work-up of parotid masses, but it should be used with caution. Due to limited sensitivity, it should not be relied upon as the sole determinant of a surgeon's management plan.

The treatment regimen for [Lu]Lu-prostate-specific membrane antigen (PSMA) 617 therapy follows that of chemotherapy: 6 administrations of a fixed activity, each separated by 6 wk. Mathematic modeling can be used to test the hypothesis that the current treatment regimen for a radiopharmaceutical modality is suboptimal. A mathematic model was developed to describe tumor growth during [Lu]Lu-PSMA therapy.

Pleomorphic adenoma (PA) is the most common benign salivary gland tumor, primarily found in the parotid gland. Recurrences often extend into the parapharyngeal space (PPS), complicating management. This report presents a case of a recurrent giant PA in the PPS following a limited excision.

This study aims to investigate the diagnostic values of fine needle aspiration cytology (FNAC) and frozen section (FS) in evaluating parotid gland masses subjected to parotidectomy. A retrospective analysis of data from 274 patients who underwent parotidectomy for parotid gland masses was performed at the Department of Otolaryngology of the University Hospital between 2013 and 2019. We compared the preoperative FNAC and intraoperative FS records with the definitive histopathological diagnoses obtained from the surgical resection specimens.

One of the most important figures of the Hellenic surgery of the 19 century, professor of the Othonian University of Athens, Theodoros Aretaios (1829-1893), portrays in his personal archives a series of surgical operations in the field of maxillofacial surgery. During his career, he operated the following surgical diseases, these are adenosarcomas or inosarcomas of the parotid region, osteofibroma of the sinus antrum, osteosarcomas of the upper and lower jaw, and lycostoma (cleft palate). He was able to perform radical enucleations of the tumorous masses.

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.
