Mucoceles are one of the most common benign soft tissue masses of the oral cavity. When they occur in the tongue, the ventral surface is the usual location. Mucoceles at the base of the tongue are extremely rare and must be differentiated from intralingual thyroglossal duct cysts. We present a case of a mucocele on the base of the tongue, which was incidentally found on a cervical spinal magnet...

This article evaluates intertalker variance of oral area, logarithm of the oral area, tongue height, and formant frequencies as a function of vowel category. The data consist of coronal magnetic resonance imaging (MRI) sequences and acoustic recordings of 5 talkers, each producing 11 different vowels. Tongue height (left, right, and midsagittal), palate height, and oral area were measured in 3 ...

Introduction: Among different kinds of oral cavity cancers, the frequency of tongue cancer occurrence is more significant. Brachytherapy is the most common method to cure tongue cancers. Long sources are used in different techniques of tongue brachytherapy. The objective of this study is to asses the dose distribution around long sources, comparing different radioisotopes as brachytherapy sourc...

Oral squamous cell carcinoma is one of the most common human neoplasms, and prevention of this malignancy requires a better understanding of its carcinogenesis process. To this end, we tried to establish an animal model using the human c-Ha-ras proto-oncogene-carrying transgenic (Tg) rats and the carcinogen 4-nitroquinoline 1-oxide (4-NQO). 4-NQO (20 p.p.m.) was administered to Tg and non-Tg ra...

The oral cavity is a rare location for the development of primary malignant melanoma. The most common primary lesion sites are the palate and gingiva. Melanoma of the tongue is specifically uncommon. A 66-year-old woman was referred to our clinic with a complaint of a huge, painless, black, discolored mass on the right side of the oral tongue for 7 years. There were no cutaneous lesions suggest...

Oral cancer is considered a great threat to public health. Tongue cancer accounts for nearly 30% of all oral cancers and usually seen in 50 to 60 year old men. Oropharyngeal cancers account for 3% of all cancers in Iran; as reported in 2003. The present study was designed to assess the epidemiologic and clinicopathologic characteristics of tongue cancer patients in two Tehran's referral univers...

Multi diameter single fiber reflectance (MDSFR) spectroscopy is a non-invasive optical technique based on using multiple fibers of different diameters to determine both the reduced scattering coefficient (μs') and a parameter γ that is related to the angular distribution of scattering, where γ = (1-g2)/(1-g1) and g1 and g2 the first and second moment of the phase function, respectively. Here we...

Oral nodular chronic hyperplastic candidiasis (CHC) is a rare subset of oral CHC, relatively uncommon condition associated with immunosuppression. We present case 73-year-old female CHC the tongue and medical history noted for type 2 diabetes. Additionally, we discuss diagnosis, management, conditions potentially CHC.

Despite widening interest in the possible association between infection/ inflammation and cancer development, knowledge of this issue in relation to oral cancer remains inadequate. This study aimed to determine the susceptibility of Apc-mutant Kyoto Apc Delta (KAD) rats, which are vulnerable to developing inflammation-associated colorectal carcinogenesis, to 4-nitroquinoline 1-oxide (4-NQO)-ind...

OBJECTIVES To quantify functional and other outcomes after major resection and fasciocutaneous free-flap reconstruction of the tongue and floor of mouth, and to describe reconstructive technique. DESIGN A hypothesis-generating, retrospective cohort study of 43 patients who underwent, at minimum, a hemiglossectomy and resection of the floor of the mouth for oral cancer followed by fasciocutane...
