Objective: Salivary gland choristomas or their neoplastic derivatives may appear throughout the intracranial space, most frequently in the middle ear or sella. Here, we present the case of a salivary gland choristoma embedded within the optic nerve dural sheath and review the literature of intracranial salivary gland masses.
Case Presentation: A 28-year-old female patient presented with headache and visual complaints. Magnetic resonance imaging revealed a prechiasmatic suprasellar cystic lesion. Operatively, the mass appeared as a cyst filled with mucinous fluid associated with abnormal tissue embedded within the optic nerve.
Results: We deflated and biopsied the cyst, which revealed normal-appearing salivary tissue. The patient remains asymptomatic without radiographic evidence of cyst recurrence 2 years postoperatively.
Conclusion: Intracranial salivary tissue has been previously described but never before in the suprasellar space. Although rare, knowledge of their natural history and pathologic features may inform surgical management if they are encountered in the operating room.

Objectives: The Milan System for Reporting Salivary Gland Cytopathology (MSRSGC) categorizes fine needle aspiration and cytology (FNAC) results into 6 tiers and assigns a risk of malignancy (ROM) to each category. Its utility in submandibular gland lesions remains unclear. Our article aims to study (1) the utility of the MSRSGC in classifying FNAC of submandibular gland masses, (2) describe the demographics and incidence of submandibular gland malignancy in our population, and (3) analyze the accuracy of FNAC in diagnosis of benign and malignant submandibular gland tumors.

: Acinic cell carcinoma (ACC) is a rare lung neoplasm that can affect both children and adults as a parenchymal or endobronchial mass. It is histologically similar to this kind of tumor described in salivary glands, but with a different immunophenotype. In general, it poses a reduced degree of malignancy, with indolent growth and a favorable prognosis, with exceptionally rare cases associated with recurring disease or lymph node metastases.

Salivary gland dysfunctions are common conditions variously related to aging, inflammatory players, and any other factor able to alter their normal physiology. These conditions may significantly impact oral and systemic health, affecting the overall quality of life. Over time, numerous therapeutic strategies have been explored to regenerate, repair, or replace injured salivary glands, focusing on those molecular and cellular mechanisms able to be safely translated into a clinical landscape.

Objectives: To address the lack of nerve and blood supply after labial salivary gland transplantation (LSGT) resulting in glandular atrophy. We designed a modified LSGT, called insular infraorbital neurovascular pedicle LSGT, and evaluated the postoperative efficacy.
Design: This is a prospective, single-centre, self-contained study.

Objectives: We aimed to calculate the age-adjusted incidence rate of head and neck cancer (HNC) in South Korea from 1999 to 2020 and investigate the incidence trend of HNC excluding the effect of population aging.
Methods: Data were obtained from the Cancer Registration Statistics Program. All 12 types of HNCs were analyzed.
