The markers considered in this study are GGT (γ-GTP), CAR (C-reactive protein (CRP)-to-Alb Ratio), GLR (GGT-to-Lymphocytes Ratio), GPR (GGT-to-Platelet ratio), GNR (GGT-to-Neutrophil ratio), NLR (Neutrophil-to-Lymphocyte ratio), PLR (platelet-to-lymphocytes ratio), OPNI (Onodera`s prognostic nutritional index), PINI (Prognostic Immune and Nutritional Index) and Albumin (Alb).

A Case of a Dentigerous Cyst with a Malformed Tooth in the Mandible of a Child.

This study reports a rare case of a dentigerous cyst in a malformed tooth in the mandible of a 5-year-old Japanese boy. Panoramic radiography revealed a cystic lesion with hard tissues inside. The patient underwent surgery under general anesthesia.

Submandibular Gland Invasion From a Metastatic Lymph Node in Patients With Buccal Mucosal Squamous Cell Carcinoma: A Case Report.

This report presents a rare case of direct invasion from a metastatic submandibular lymph node (SMLN) to submandibular gland (SMG) in a resected specimen of neck dissection (ND) of buccal mucosal squamous cell carcinoma (SCC). The patient was an 82-year-old woman with a clinical diagnosis of the left buccal mucosal SCC (cT4bN2bM0, Stage IVB). The tracheostomy, modified radical neck dissection, buccal mucosal cancer resection including maxillary partial resection, mandibular segmentectomy, and reconstructive surgery with a plate and a free rectus abdominis flap were performed.

The inflammatory markers and locoregional pathological results both have an impact on the prognosis of oral squamous cell carcinoma in patients who have undergone neck dissection.

Background: Locoregional surgical pathology, with surgical margins at the primary site and lymph node (LN) metastasis, particularly extranodal extension (ENE), plays an important role in the prognosis of oral squamous cell carcinoma (OSCC). In addition, systemic inflammatory response and nutritional status are associated with poor prognosis.

Purpose: This study aimed to comprehensively assess the effect of inflammatory markers and locoregional factors on the prognosis of patients with OSCC who underwent neck dissection (ND).

Predictors of Occult Metastasis and Prognostic Factors in Patients with cN0 Oral Cancer Who Underwent Elective Neck Dissection.

Elective neck dissection (END) is recommended for the management of patients with oral squamous cell carcinoma (OSCC) because of the risk of occult metastasis (OM). We hypothesized that some factors predict poor prognosis regardless of a cN0 END. This study aimed to investigate the predictors of OM and prognostic factors in patients with cN0 OSCC who underwent supraomohyoid neck dissection (SOHND).

Involvement of submandibular gland in oral squamous cell carcinoma.

Background: The submandibular gland (SMG) is sacrificed during neck dissection in patients undergoing curative surgery for oral squamous cell carcinoma (OSCC). This may cause a decrease in the production of saliva and result in xerostomia.

Purpose: This study aimed to determine the incidence, invasion patterns, risk factors, and prognosis of SMG involvement in OSCC.

Macrophage specific restoration of the Nrf2 gene in whole-body knockout mice ameliorates steatohepatitis induced by lipopolysaccharide from Porphyromonas gingivalis through enhanced hepatic clearance.

Lipopolysaccharide (LPS) derived from Porphyromonas gingivalis (P.g.), which causes periodontal disease, contributes to the development of non-alcoholic steatohepatitis (NASH).

p62 Is a Potential Biomarker for Risk of Malignant Transformation of Oral Potentially Malignant Disorders (OPMDs).

To determine the intracellular behavior of p62, a marker of selective autophagy, in oral potentially malignant disorders (OPMDs). This retrospective study includes 70 patients who underwent biopsy or surgical resection and were definitively diagnosed with OPMDs. Immunohistochemical staining for p62, XPO1, p53, and ki67 was performed on all samples and positive cell occupancy was calculated.

Long-term control of lung metastasis of tongue cancer treated effectively with cetuximab combination chemotherapy.

Generally, systemic chemotherapy is indicated for oral squamous cell carcinoma with distant metastasis and has a poor prognosis. Recently, the advent of molecular targeted drugs, such as cetuximab and immune checkpoint inhibitors, has dramatically improved prognosis, though controlling distant metastasis remains challenging. We report a case of tongue cancer in which lung metastases disappeared in the long term.

A Case of Tophaceous Pseudogout with Destruction of the Skull Base at the Temporomandibular Joint.

We report a case of tophaceous pseudogout that occurred in the temporomandibular joint (TMJ) and presented with skull base destruction. The patient was a 73-year-old woman, who complained of an obstructed ear sensation in December 2021. The otolaryngological examination was unremarkeable, and a computed tomography scan revealed a calcified lesion in the left TMJ.

Anterior Maxillary Distraction Osteogenesis With Bone-borne Intraoral Buccal Devices for Maxillary Hypoplasia With Cleft Lip and Palate.

Anterior maxillary distraction osteogenesis (AMDO) surgery for cleft lip and palate involves distraction of a segment of the anterior maxilla and advancement using 2 intraoral buccal bone-borne distraction devices. The anterior part of the maxilla is advanced anteriorly with less relapse which increases maxillary length and does not affect speech. We aimed to evaluate the effects of AMDO, including lateral cephalometric changes.

Postoperative Deep Sedation after Microvascular Reconstructive Surgery for Oral Cancer Increases the Risk of Early Postoperative Pneumonia.

This study investigated the effect of postoperative deep sedation after oral cancer reconstructive surgery on the occurrence of early postoperative pneumonia and early postoperative delirium. We obtained medical records of 108 consecutive patients who underwent microvascular reconstructive surgery at Tsukuba University Hospital for oral cancer between January 2013 and December 2021. Forty-six of them woke soon after surgery.

A Case of Primary Intraosseous Squamous Cell Carcinoma Arising in Dentigerous Cyst of Mandible.

Primary intraosseous squamous cell carcinoma (PISCC) arising from dentigerous cysts (DCs) is rare. Herein, we present a rare case of a 35 year-old Japanese man with PISCC arising from a DC. Clinicians should be aware of the potential for malignant changes to SCC in asymptomatic DCs and should conduct follow-up.

Age Related Immunosenescence Epstein-Barr Virus-positive Mucocutaneous Ulcer of the Palate Mimicking Medication-related Osteonecrosis of the Jaw.

Epstein-Barr virus (EBV) -positive mucocutaneous ulcer (EBVMCU) was first described as a lymphoproliferative disorder in 2010. In recent years, EBVMCU has been reported in the field of oral surgery. On the other hand, medication-related osteonecrosis of the jaw (MRONJ) is an osteomyelitis that occurs in patients receiving antiresorptive agents including bisphosphonates (BP) and/or denosumab developing with bacterial infections such as dental diseases and mucositis.

Osseous Choristoma of the Tongue: A Case Report.

We report a case of a 40-year-old Japanese woman with a benign tongue tumor diagnosed as osseous choristoma of the tongue. Resection of the tongue tumor was performed under general anesthesia. The gross examination of the resected specimen showed a bone-like mass measuring 5 × 5 × 3 mm, surrounded by soft tissue.

A Case of Tooth Extraction in a Patient with Food-Dependent Exercise Induced Anaphylaxis.

A 29-year-old Japanese man with food-dependent exercise-induced anaphylaxis (FDEIA) underwent tooth extraction under general anesthesia. FDEIA is a rare condition in which anaphylaxis occurs due to exercise load or oral administration of NSAIDs after ingestion of allergens. Wheat is often the cause in FEDIA, defined as wheat-dependent exercise-induced anaphylaxis (WDEIA).

Convenient Decision Criteria for Surgery in Elderly Patients with Oral Squamous Cell Carcinoma.

Elderly patients with oral squamous cell carcinoma (OSCC) have difficulty undergoing curative surgical treatment due to various factors besides age. The purpose of the present study was to study the factors determining surgery in elderly patients with OSCC. We designed and implemented a retrospective cohort study.

Protocol for a multicentre, prospective observational study of elective neck dissection for clinically node-negative oral tongue squamous cell carcinoma (END-TC study).

Introduction: In early-stage oral tongue squamous cell carcinoma (OTSCC), elective neck dissection (END) is recommended when occult lymph node metastasis is suspected; however, there is no unanimous consensus on the risks and benefits of END in such cases. The management of clinically node-negative (cN0) OTSCC remains controversial. This study, therefore, aimed to evaluate the efficacy of END and its impact on the quality of life (QoL) of patients with cN0 OTSCC.

Accidental Insertion of a Broken Needle into the Pterygoid Mandibular Space during Inferior Alveolar Nerve Block: A Case Report.

The incidence of needle breakage is estimated to be 0.000007%, and most needle breaks occur during inferior alveolar nerve block (IANB) administration and are localized to the pterygomandibular space. Although immediate surgical intervention is recommended for the removal of the fracture needles, intraoperative localization of a broken injection needle fragment can be challenging.

Anatomical Variant of Spinal Accessory Nerve Passing through Fenestrated Internal Jugular Vein.

Neck dissection (ND) is a major surgery for head and neck cancer. Currently, some or all of the spinal accessory nerve (SAN), sternocleidomastoid muscle, and internal jugular vein (IJV) are aggressively preserved during ND to reduce postoperative complications. Since the anatomical relationship between the SAN and IJV has several variations, knowledge of these variations is necessary to avoid iatrogenic damage.

Lip Epidermoid Cyst Caused by a Piercing: A Report of a Rare Case.

We report the case of a lip epidermoid cyst, caused by piercing in a 23-year-old Japanese woman. She had an exophytic lesion in the lower lip associated with the piercing which was initially diagnosed as a mucous retention cyst. The lesion was resected under local anesthesia, and pathological examination revealed an epidermoid cyst, likely caused by piercings.
