Primary hyperparathyroidism: diagnostic features and surgical outcomes.

BACKGROUND: Primary hyperparathyroidism is characterized by elevated plasma calcium levels due to inappropriate secretion of parathyroid hormone (PTH) in most cases by an adenomatous or hyperplastic parathyroid. We present a retrospective analysis of a large cohort of patients operated on of parathyroidectomy in our center analyzing their diagnostic characteristics, intraoperative match and surgical outcomes. METHODS: We included patients with benign parathyroid disease who underwent parathyroidectomy associated or not with hemi- or total thyroidectomy at the Sant'Anna University Hospital of Ferrara between September 2003 and September 2022. RESULTS: In our study 371 patients fulfilled the inclusion criteria. The most widely used preoperative imaging method was ultrasound, followed by 99mTc-sestamibi scintigraphy. In most cases, preoperative imaging correctly localized the affected parathyroid. Considering the intraoperative site of the pathologically affected parathyroid, the majority of pathological parathyroids were located in the lower districts of the neck and a smaller percentage in the upper, intermediate, and ectopic sites. Postoperative complications were infrequent. CONCLUSIONS: The main challenge in parathyroid surgery lies in the difficulty in localizing the pathological parathyroid at the surgical site, which can lengthen the surgical time by increasing comorbidities. Currently, the results on pathological parathyroid localization are good. Technology needs to be developed toward greater diagnostic accuracy and minimally invasive surgical approaches.

Clear-Cell Renal Cell Carcinoma Metastasis into Pterygomaxillary Fossa - A Case Report.

Rationale: The aim of this study is to describe a rare case of clear-cell renal cell carcinoma (ccRCC) metastasis to the pterygomaxillary fossa. Patient Concerns: A 54-year-old woman was referred to the Department of Otolaryngology due to right facial pain for the past six weeks. Diagnosis: ccRCC metastasis to the pterygomaxillary fossa. Treatment: The patient was treated by immunotherapy (Ipilimumab + Nivolumab) after multidisciplinary team evaluation. Outcomes: After 18 months, the patient is in good overall condition and the size of the skull base lesion has significantly reduced. Take-Away Lessons: ccRCC metastasis to the skull base and adjacent sites occur rarely. Most commonly, the presenting symptoms of these lesions are headache and diplopia for skull base metastases and epistaxis in case of sinusal involvement, according to the literature. When total resection of the metastasis is not feasible, tumour-targeted therapy may be used, as in the presented case. A multidisciplinary evaluation is recommended for the correct assessment and management of these patients.

Reconstructive Options after Oncological Rhinectomy: State of the Art.

BACKGROUND: The nose is a central component of the face, and it is fundamental to an individual's recognition and attractiveness. The aim of this study is to present a review of the last twenty years literature on reconstructive techniques after oncological rhinectomy. METHODS: Literature searches were conducted in the databases PubMed, Scopus, Medline and Google Scholar. "Preferred Reporting Items for Systematic Reviews and Meta-analysis (PRISMA)" for scoping review was followed. RESULTS: Seventeen articles regarding total rhinectomy reconstruction were finally identified in the English literature, with a total of 447 cases. The prostheses were the reconstructive choice in 213 (47.7%) patients, followed by local flaps in 172 (38.5%) and free flaps in 62 (13.8%). The forehead flap (FF) and the radial forearm free flap (RFFF) are the most frequently used flaps. CONCLUSIONS: This study shows that both prosthetic and surgical reconstruction are very suitable solutions in terms of surgical and aesthetic outcomes for the patient.
