Background: The submental island flap (SIF) is a pedicled flap based upon the submental artery and vein. Its utility in reconstruction following ablative head and neck procedures has been applied to various subsites including skin, lip, buccal mucosa, retromolar trigone, parotidectomy defects, and tongue. We review our experience using the SIF for reconstruction following tumor ablation. Methods: This prospective case series with medical record review includes consecutive patients undergoing SIF reconstruction following ablative surgery for malignancy at a single tertiary care facility between November 2014 and November 2016...

Objectives: Management of neck metastases in terms of diagnosis and treatment has always been a controversial issue in patients of head and neck malignancy. The main area of debate in case of diagnosis lies with the fact that whether we should rely on ultrasound, as a diagnostic modality for diagnosing micrometastases in the neck in head and neck malignancy patients? The second controversial issue is the management of N0 neck, whether to be radical or conservative? Materials and Methods: This study was conducted on 70 diagnosed patients of head and neck carcinoma who were planned for resection of the primary...

Head and neck squamous cell carcinomas (HNSCC) are a diverse group of tumor types, including neoplasia of the paranasal sinuses, oral cavity, trachea, pharynx and larynx. Laryngeal cancer is the most common type of HNSCC. The proline-rich 4 (PRR4) protein is synthesized in the acinar cells of human lacrimal glands. Previous studies have demonstrated that PRR4 may function as an antimicrobial protein protecting the ocular surface and the oral cavity. In order to determine differentially expressed genes (DEGs) in laryngeal tumors, a GeneFishing Assay was performed; 27 DEGs were identified...

Background: Along with the advances in technology of three-dimensional (3D) printer, it became a possible to make more precise patient-specific 3D model in the various fields including oral and maxillofacial surgery. When creating 3D models of the mandible and maxilla, it is easier to make a single unit with a fused temporomandibular joint, though this results in poor operability of the model. However, while models created with a separate mandible and maxilla have operability, it can be difficult to fully restore the position of the condylar after simulation...

Granular cell tumors (GCTs) are rare and benign tumors that can occur at any anatomical site. GCTs are thought to originate from nerve cells, particularly Schwann cells. Their name derives from the fact that an accumulation of cytoplasmic lysosomes imparts the tumor with a granular appearance. They are most commonly observed in the oral cavity, skin and subcutaneous tissue, breast, and respiratory tract. Granular cell tumors rarely affect the gastrointestinal tract. We report a 58-year-old female with a past medical history of hypertension, mitral valve prolapse, and depression who presented for surveillance colonoscopy...

Myopericytomas are rare benign tumors that show a distinctive, concentric perivascular proliferation of oval to spindle-shaped myoid-appearing cells that are predominantly arranged concentrically around thin-walled vascular channels. These lesions are similar in histologic appearance to hemangiopericytomas, myofibromas, and glomus tumors. The myopericytoma is usually found in the distal extremities, but a handful of reports have shown the lesion to be present in the oral cavity. A review of the literature to date shows only 4 other reported cases of myopericytomas occurring in the lips...

Sodium 4-phenylbutyrate (PBA), which exerts a wide range of anti-inflammatory effects, is rapidly cleared from the body (approximately 98%) by urinary excretion by 24 h after oral treatment in humans. PBA was almost entirely excreted to urine as phenylacetyl glutamine (PAGln). However, no data describe the potential anti-inflammatory effects of PAGln. The purpose of this study was to evaluate the anti-inflammatory effects of PAGln on mouse spleen cells and peritoneal cavity cells, and explore the potential mechanism underlying this effect...

PURPOSE OF REVIEW: The quantity of tissue removed during an oncologic surgical procedure is not standardized and there are numerous reports of local recurrence despite histologically adequate resection margins. The oral cavity is one of the sites in the head and neck with high chances of recurrence following negative margins. To address this need, this article reviews the recent applications of Dynamic Optical Contrast Imaging (DOCI) towards both oral screening and the intraoperative evaluation of tumor margins in head and neck surgery...

Introduction: Oral squamous cell carcinoma (OSCC) accounts 94% of all malignant lesions in the oral cavity. In the assessment of OSCC, nowadays the WHO grading system has been followed widely but due to its subjectivity, investigators applied the sophisticated technique of computer-assisted image analysis in the grading of carcinoma in larynx, lungs, esophagus, and cervix to make it more objective. Aims and Objectives: Access, analyze, and compare the cellular area (CA); cytoplasmic area (Cyt A); nuclear area (NA); nuclear perimeter (NP); nuclear form factor (NF); and nuclear-cytoplasmic ratio (N/C) of the cells in different grades of OSCC...

Rhabdomyosarcoma is a malignant skeletal muscle neoplasm. The tumor is much more common in children, and the most frequent site is head and neck region. Since this tumor is less frequent than other neoplasms in oral cavity, the clinicians sometimes ignore it, working the patients up. Rhabdomyosarcoma is a high-grade malignancy with poor prognosis. Considering the aggressive behavior and various clinical or histopathologic presentations of the tumor, early diagnosis has a significant impact on the treatment outcome and prognosis of the patients...

BACKGROUND: Human papillomavirus (HPV) prevalence in oropharynx squamous cell carcinoma (OPSCC) is on the rise. HPV-linked OPSCCs represent a distinct clinical entity with a better treatment response and patient survival compared to tumors not linked to HPV. An emerging role in treatment response has been attributed to immune cell infiltration in human tumors. In this study, we investigated immune cell infiltration in human SCC of the head and neck region and its relation to overall survival after treatment with surgery (with or without radiotherapy) or concomitant chemo (or cetuximab)-radiotherapy...

Tumor metastasis to the oral cavity is rare and is usually an indication of late-stage disease and poor prognosis. While, there are reports of renal cell carcinoma (RCC) metastatic to oral cavity, vast majority of them are to the jaw. Herein, we present a case of a 78-year-old woman with RCC metastasis limited to the oral soft tissue without any bone involvement. As the lesion solely involved maxillary gingiva, it clinically mimicked that of a pyogenic granuloma, which is a reactive, nonneoplastic condition...

Polymorphous adenocarcinoma (PAC) is a distinctive salivary gland neoplasm that predominantly occurs in the minor salivary glands. The tumor is characterized by cytological uniformity, morphological diversity, an infiltrative growth pattern and low metastatic potential. It presents as an asymptomatic, slow- growing mass within the oral cavity. This salivary gland tumor is difficult to diagnose both clinically and histopathologically due to its indolent presentation and diverse architectural pattern which includes various microscopic patterns namely- solid, ductal-tubular, cribriform, trabecular and single-file growth...

Oral cavity is not a usual site for metastasis, accounting about 1% of all oral tumors. The majority site for metastasis is the mandible and less common the maxilla followed by intraoral soft tissue. These tumors may be the first clinical manifestation of the primary lesion. One of the most important sites of the primary neoplasm that metastasizes to the jaws is kidney. Therefore, considering to this fact that the metastatic tumors always are not seen in a typical site, it is necessary to rule out the metastatic carcinomas to jaws...
