Pediatric Sublingual Dermoid Cyst: Diagnostic Challenges and Surgical Management in a 13-Year-Old Boy.

BACKGROUND Ranulas are typical causes of sublingual cysts in children. However, our case was histopathologically confirmed to be a dermoid cyst. Epidermoid and dermoid cysts of the floor of the mouth account for <0.

Modular anatomic approach to oral tongue carcinoma: functional outcomes and quality of life.

Objectives: The purpose of this study is to present the long-term functional swallowing outcomes of various surgical approaches to oral tongue/floor of mouth squamous cell carcinoma (OTFOMSCC) according to a modular and compartment-based concept previously described elsewhere.

Methods: A retrospective study was conducted on patients undergoing surgery for OTFOMSCC from January 2017 to April 2023 in the Department of Otorhinolaryngology at the Hospital of Bolzano. Functional swallowing outcomes and quality of life (QoL) were assessed through the administration of a scale and questionnaires between 6 months and 1 year postoperatively or after the end of adjuvant therapy, stratifying the results according to the surgical technique used.

Recurrent aphthous stomatitis and neoplasms of the mouth and pharynx: a two-sample Mendelian randomization study.

Background: The association between recurrent aphthous stomatitis (RAS) and neoplasms of the mouth and pharynx (NOMAP) has been reported in some previous observational studies. However, causality is still confused. Our research aims to explore the relationship between RAS and NOMAP through a Mendelian randomization (MR) analysis and to explore whether RAS can serve as a risk factor for NOMAP to provide a reference for the clinical strategy.

The Sublingual Gland Flap for Oral Reconstruction: Insights From a Single Institutional Experience.

Following ablative surgery, the reconstruction of oral cavity defects is essential to ensure optimal function and aesthetically acceptable outcomes. The purpose of this study was to retrospectively analyze the effectiveness and complication rates of the sublingual gland flap (SGF) in oral soft tissue reconstruction. The procedure for harvesting SGF and the strengths and limitations of the flap are discussed.

Uncommon and Challenging Phenotypes of High-Risk Human Papillomavirus-Associated Head and Neck Carcinomas Revealed by High-Throughput Studies.

Background: HPV- associated squamous cell carcinoma (SCC) is uncommon in non-oropharynx sites and not well characterized. This study aims to investigate uncommon phenotypes of HPV-associated head and neck carcinoma, the prevalence and morphologic spectrum of HPV-associated SCC in the oral cavity, larynx and hypopharynx.

Method: P16 immunostaining and HPV E6/7 in situ hybridization (ISH) were performed on tissue microarrays comprised of SCCs from different anatomic sites: oropharynx (n = 270), hypopharynx (n = 52), oral cavity (n = 95) and larynx (n = 123).

Development of F-Fluoromisonidazole Hypoxia PET/CT Diagnostic Interpretation Criteria and Validation of Interreader Reliability, Reproducibility, and Performance.

Tumor hypoxia, an integral biomarker to guide radiotherapy, can be imaged with F-fluoromisonidazole (F-FMISO) hypoxia PET. One major obstacle to its broader application is the lack of standardized interpretation criteria. We sought to develop and validate practical interpretation criteria and a dedicated training protocol for nuclear medicine physicians to interpret F-FMISO hypoxia PET.

Tumor Bed Margins Versus Specimen Margins in Oral Cavity Cancer: Too Close to Call?

Introduction: The routine assessment of intraoperative margins has long been the standard of care for oral cavity cancers. However, there is a controversy surrounding the best method for sampling surgical margins. The aim of our study is to determine the precision of a new technique for sampling tumor bed margins (TBMs), to evaluate the impact on survival and the rate of free flap reconstructions.

[Clinical application of free peroneal artery leaflet perforator flap in postoperative complex defect of oral cancer].

To investigate the clinical effect of a segmented perforator flap of free peroneal artery to repair a complex defect after oral cancer. Forty-eight patients with oral cancer admitted to the Department of Oral and Maxillofacial Surgery of the First Affiliated Hospital of Bengbu Medical College from January 2018 to January 2022, including 8 of buccal cancer, 7 of floor cancer, 14 of tongue cancer, 5 of retromolar cancet, 9 of maxillary gingival cancer and 5 of mandibular gingival cancer. After lesion resection, 24 patients in the experimental group used the partial perforator flap to repair the defect, and 24 patients in the control group used the single flap to repair the defect.

Hyalinizing clear cell carcinoma of the sublingual gland: A case report and literature review.

Rationale: Hyalinizing clear cell carcinoma (HCCC) of the salivary glands is a rare low-grade malignant tumor. This type of tumor is particularly uncommon in the sublingual glands.

Patient Concerns: A 57-year-old female with a mass on the left side of the floor of the mouth that had been present for 2 months.

Reconstruction of Defects After Oral Cancer Surgery With the Superior Thyroid Artery Perforator Flap.

Objective: The superior thyroid artery perforator flap (STAPF) was previously presented as a type of locoregional pedicled flap for lateral facial and temple defects. In this study, we aimed to present our clinical experience with this flap for the reconstruction of soft tissue defects after oral cancer surgery.

Methods: From February 2019 to December 2022, 24 patients with oral cancers at the School and Hospital of Stomatology, Peking University were included.

Basaloid squamous cell carcinoma in the mandibular alveolus: A rare case report with differential diagnosis.

Basaloid squamous cell carcinoma (BSCC) is a distinct, high-grade variant of oral squamous cell carcinoma (OSCC) with a poor prognosis. In the head and neck region, the most common sites are the epiglottis, piriform sinus, and tongue base. Other less common sites include the floor of the mouth, oral mucosa, palate, tonsils, nasopharynx, and trachea.

Submandibular and sublingual salivary gland involvement in adenoid cystic carcinoma.

Adenoid cystic carcinoma (AdCC) is a malignant salivary gland neoplasm that presents as an indolent but aggressive neoplasm. AdCC histogenesis is linked to the intercalated ducts of the salivary glands, equally affecting the major and minor glands. AdCC is associated with distant metastasis, most commonly to the lungs, and a high recurrence rate.
