Closure of oroantral fistula

Awang MN

Int J Oral Maxillofac Surg, 1988 Apr;17(2):110-5.

PMID: 3133418

Oroantral fistula is an uncommon complication in oral surgery. Although smaller fistulas of less than 5 mm in diameter may close spontaneously, larger fistulas always require surgical closures. The literature review revealed various procedures for the closure of oroantral fistulas. These procedures may be subdivided into local flap, distant flap and grafting. Procedures involving local flaps are usually adequate to close minor to moderate size defects. Those procedures utilizing the buccal mucoperiosteal flap as the tissue closure include straight-advancement, rotated, sliding and transversal flap procedures; while those involving the palatal mucoperiosteum are straight advancement, rotational-advancement, hinged and island flap procedures. The combinations of various local flaps to strengthen the tissue closure are also being advocated. The advantages and the limitations of these procedures are discussed. Distant flaps and bone grafts are usually indicated in the closure of larger defects in view of their greater tissue bulks. Tongue flaps have superseded extra-oral flaps from extremities and forehead for aesthetic reasons and also in view of their similar tissue replacement. Various tongue flap procedures are described. At present, various alloplastic materials such as gold, tantalum and polymethylmethacrylate are infrequently reported in the closure of oroantral fistulas. However, in the light of successful reports over the use of biological materials, collagen and fibrin, in the closure of oroantral fistulas, there seems to be another simple alternative technique for treating oroantral fistulas.

Congenital Midline Tongue Base Mass in An Infant: Lingual Hamartoma

Fadzilah N, Azman M, See GB

J Clin Diagn Res, 2016 Sep;10(9):MD01-MD03.

PMID: 27790477

Lingual hamartoma is a rare finding of congenital midline posterior tongue mass. The lesion may be seen as a single anomaly or maybe associated with syndrome especially the Oral Facial Digital Syndrome (OFDS). Here, we report an otherwise normal and healthy two-month-old boy with a congenital midline base of tongue mass presented with snoring and episodic vomiting since the age of 1 month. Tumour excision from the area of foramen of caecum recovered a pinkish pedunculated tumour. Histopathology examination confirmed the diagnosis of leiomyomatous lingual hamartoma. Differential diagnosis, especially for midline tongue mass and other paediatric tongue lesions are discussed. We also discuss the epidemiology, histopathologic features, treatment and prognosis of lingual hamartoma based on the literature review.

Fulltext A magnetic resonance imaging study on the articulatory and acoustic speech parameters of Malay vowels

Zourmand A, Mirhassani SM, Ting HN, Bux SI, Ng KH, Bilgen M, et al.

Biomed Eng Online, 2014;13:103.

PMID: 25060583 DOI: 10.1186/1475-925X-13-103

The phonetic properties of six Malay vowels are investigated using magnetic resonance imaging (MRI) to visualize the vocal tract in order to obtain dynamic articulatory parameters during speech production. To resolve image blurring due to the tongue movement during the scanning process, a method based on active contour extraction is used to track tongue contours. The proposed method efficiently tracks tongue contours despite the partial blurring of MRI images. Consequently, the articulatory parameters that are effectively measured as tongue movement is observed, and the specific shape of the tongue and its position for all six uttered Malay vowels are determined.Speech rehabilitation procedure demands some kind of visual perceivable prototype of speech articulation. To investigate the validity of the measured articulatory parameters based on acoustic theory of speech production, an acoustic analysis based on the uttered vowels by subjects has been performed. As the acoustic speech and articulatory parameters of uttered speech were examined, a correlation between formant frequencies and articulatory parameters was observed. The experiments reported a positive correlation between the constriction location of the tongue body and the first formant frequency, as well as a negative correlation between the constriction location of the tongue tip and the second formant frequency. The results demonstrate that the proposed method is an effective tool for the dynamic study of speech production.

Wasted tongue in neuromyelitis optica spectrum disorders due to hypoglossal nerve involvement

Viswanathan S

Mult Scler, 2015 Apr;21(4):488-91.

PMID: 24948685 DOI: 10.1177/1352458514537698

We report two cases of neuromyelitis optica spectrum disorder with hypoglossal nerve involvement resulting in a wasted tongue associated with other brainstem symptoms of hypogeusia, hypersalivation, hiccough, increased sweating, hyperemesis and myelitis (in the second patient). This occurred due to involvement of the hypoglossal, tractus solitarius and dorsal vagal nuclei. Though the myelitis and other brainstem signs recovered the hypoglossal nerve involvement resulting in a unilateral wasted tongue did not. It is important to consider neuromyelitis optica and its spectrum disorders in the differential diagnosis of a wasted tongue though its occurrence is rare.

Fulltext Long chain N-acyl homoserine lactone production by Enterobacter sp. isolated from human tongue surfaces

Yin WF, Purmal K, Chin S, Chan XY, Chan KG

Sensors (Basel), 2012;12(11):14307-14.

PMID: 23202161 DOI: 10.3390/s121114307

We report the isolation of N-acyl homoserine lactone-producing Enterobacter sp. isolate T1-1 from the posterior dorsal surfaces of the tongue of a healthy individual. Spent supernatants extract from Enterobacter sp. isolate T1-1 activated the biosensor Agrobacterium tumefaciens NTL4(pZLR4), suggesting production of long chain AHLs by these isolates. High resolution mass spectrometry analysis of these extracts confirmed that Enterobacter sp. isolate T1-1 produced a long chain N-acyl homoserine lactone, namely N-dodecanoyl-homoserine lactone (C12-HSL). To the best of our knowledge, this is the first isolation of Enterobacter sp., strain T1-1 from the posterior dorsal surface of the human tongue and N-acyl homoserine lactones production by this bacterium.

We report a case in a young man who developed acute, persistent and painful tongue protrusion followed by swelling for more than 24 hours. He had relapse symptoms of schizophrenia and had recently received a single dose of parenteral haloperidol to manage his agitation. His record showed history of similar event and he has been taking atypical antipsychotic for maintenance. Mental state examination on admission revealed an agitated man with disorganised speech, restricted affect, auditory hallucination and persecutory delusion. His dystonia and oedema improved after 3 days. His mental status also recovered with the maintenance of low-potency antipsychotic and anticholinergic antiparkinsonian medications.

Fulltext Iatrogenic lingual neuralgia following laryngoscopy

Aziah Ab Rani, Nadarajah, Sanjeevan

Journal of Clinical and Health Sciences, 2018;3(2):48-50.

MyJurnal

Tongue pain attributed to lingual neuralgia has been reported following dental and oral surgical procedures. Lingual nerve insult through traction and compression during laryngoscopic examination has been proposed as possible etiology for lingual nerve neuralgia. We report a case of tongue ischemia during laryngoscopic procedure which resulted in lingual neuralgia. We recommend that intermittent release of pressure by relaxing the instrument or gag and monitoring the perfusion state of the tongue will reduce the risk of this lingual neuralgia.

Bimodal neuromodulation combining sound and tongue stimulation reduces tinnitus symptoms in a large randomized clinical study

Conlon B, Langguth B, Hamilton C, Hughes S, Meade E, Connor CO, et al.

Sci Transl Med, 2020 10 07;12(564).

PMID: 33028707 DOI: 10.1126/scitranslmed.abb2830

Tinnitus is a phantom auditory perception coded in the brain that can be bothersome or debilitating, affecting 10 to 15% of the population. Currently, there is no clinically recommended drug or device treatment for this major health condition. Animal research has revealed that sound paired with electrical somatosensory stimulation can drive extensive plasticity within the brain for tinnitus treatment. To investigate this bimodal neuromodulation approach in humans, we evaluated a noninvasive device that delivers sound to the ears and electrical stimulation to the tongue in a randomized, double-blinded, exploratory study that enrolled 326 adults with chronic subjective tinnitus. Participants were randomized into three parallel arms with different stimulation settings. Clinical outcomes were evaluated over a 12-week treatment period and a 12-month posttreatment phase. For the primary endpoints, participants achieved a statistically significant reduction in tinnitus symptom severity at the end of treatment based on two commonly used outcome measures, Tinnitus Handicap Inventory (Cohen's d effect size: -0.87 to -0.92 across arms; P < 0.001) and Tinnitus Functional Index (-0.77 to -0.87; P < 0.001). Therapeutic improvements continued for 12 months after treatment for specific bimodal stimulation settings, which had not previously been demonstrated in a large cohort for a tinnitus intervention. The treatment also achieved high compliance and satisfaction rates with no treatment-related serious adverse events. These positive therapeutic and long-term results motivate further clinical trials toward establishing bimodal neuromodulation as a clinically recommended device treatment for tinnitus.

Soil requires load bearing impact assessment for stability. Therefore, this study aims to utilize the multi-channel analysis surface wave (MASW) for soil subsurface investigation and profiling around Peninsular Malaysia. The standard penetration test (SPT) was conducted for comparison between factual N-value and computed N-value from shear wave velocity (Vs ) obtained from MASW using the Imai and Tonouchi equation. The correlation coefficient (R) and coefficient of determination, (R2 ), showed strong relationship between factual N-value and computed N-value. The model of Vs and factual N-value data distribution is non-normal but the analyzed relationship shows a significant level of p-value < 0.05. The R2 for each location of Vs -N-value relationship are ranging from 0.5 to 0.9.

Renal cancer is a rare occurrence in all adult malignancies, and renal cell carcinoma (RCC) is the most common type. Due to its aggressive behaviour and high tendency for metastasis, manifestation of RCC varies, often with non-urologic features or symptoms from metastatic sites. Metastatic RCC to the head and neck region is rare particularly to the tongue are extremely rare. We report an elderly lady who presented with recurrent tongue mass metastasis from RCC, a rare cancer with even rarer metastatic site.

PMID: 35312982 DOI: 10.1007/s12105-021-01402-9

The fifth chapter of the upcoming fifth edition of the 2022 World Health Organization Classification of Tumours of the Head and Neck titled Tumours of the oral cavity and mobile tongue, has had some modifications from the 2017 fourth edition. A new section "Non-neoplastic Lesions", introduces two new entries: necrotizing sialometaplasia and melanoacanthoma. The combined Oral potentially malignant disorders and Oral epithelial dysplasia section in the 2015 WHO has now been separated and submucous fibrosis and HPV-associated dysplasia are also discussed in separate sections. Carcinoma cuniculatum and verrucous carcinoma are described in dedicated sections, reflecting that the oral cavity is the most common location in the head and neck for both these entities which have distinct clinical and histologic features from conventional squamous cell carcinoma. This review summarizes the changes in Chapter 5 with special reference to new additions, deletions, and sections that reflect current clinical, histological, and molecular advances.

Fulltext World Workshop on Oral Medicine VII: Clinical evidence of differential expression of lncRNAs in oral squamous cell carcinoma: A scoping review

Pentenero M, Bowers LM, Jayasinghe R, Yap T, Cheong SC, Kerr AR, et al.

Oral Dis, 2019 Jun;25 Suppl 1(Suppl 1):88-101.

PMID: 31140697 DOI: 10.1111/odi.13076

BACKGROUND: Long non-coding RNAs (lncRNAs) have important roles in regulating gene expression pertaining to cell proliferation, survival, migration and genomic stability. Dysregulated expression of lncRNAs is implicated in cancer initiation, progression and metastasis.

OBJECTIVES: To explore, map and summarize the extent of evidence from clinical studies investigating the differential expression of lncRNAs in oral/tongue squamous cell carcinoma.

METHODS: PubMed, Scopus and Web of Science were used as search engines. Clinical, full-length, English language studies were included. PRISMA-ScR protocol was used to evaluate and present results. The present scoping review summarizes relationships of the differential expression of lncRNAs with the presence of tumour and with clinicopathological features including survival.

RESULTS: Almost half of the investigated transcripts have been explored in more than one study, yet not always with consistent results. The collected data were also compared to the limited studies investigating oral epithelial dysplasia. Data are not easily comparable, first because of different methods used to define what differential expression is, and second because only a limited number of studies performed multivariate analyses to identify clinicopathological features associated with the differentially expressed lncRNAs.

CONCLUSIONS: Standard methods and more appropriate data analyses are needed in order to achieve reliable results from future studies.
