“…Thereafter, four months plus, patch distortions of nearly all acini are observable and few serous cells remain while the ducts and lobules undergo fibrosis. 34 Atri et al, 22 observed that the salivary glands can tolerate ionizing radiation dose in the range of 32Gy to 46Gy. However, curative doses may range up to 60Gy and sometimes more.…”

REVIEWPlease cite this paper as: Nyathi M. Imaging salivary glands post external radiation beam therapy of head and neck tumours. AMJ 2018;11(6):335-342. ABSTRACT BackgroundRadiation therapy using external radiation beam is an established treatment for head and neck cancers. However, salivary glands are exposed leading to severe impairment of oral health. In order to devise patient care strategies, clinicians can measure the degree of salivary gland impairment using various imaging modalities. AimsThe study aimed determining the best imaging modality for measuring salivary glands impairment post external radiation beam therapy of head and neck tumours. MethodsA systematic literature review, performed using Google and Science Direct.com search engines. Publications in English on salivary gland imaging modalities post external radiation beam therapy of head and neck cancers were selected. Information on advantages and disadvantages of the imaging modalities was documented. ResultsThe study established that the Magnetic Resonance Imaging (MRI), Computer Tomography (CT), Ultra Sound (US) depict structural changes while salivary gland scintigraphy provides functional information. It was also established that the obstruction of the salivary glands can be measured using Magnetic Resonance -Sialography. ConclusionThe salivary gland scintigraphy technique is the most sensitive of all salivary gland imaging modalities with the ability to detect slight parenchymal injuries well before structural changes can be seen using the MRI, CT and US. However, when evaluating the obstruction of the salivary glands ducts, the Magnetic Resonance-Sialography modality offers the best option. What this review adds: What is known about this subject?During external beam radiation therapy of head and neck tumours, salivary glands are impaired leading to oral complications among patients. What new information is offered in this review?Salivary glands scintigraphy detects the slightest changes in the function of the salivary glands well before structural changes can be detected using the MRI, the CT and US. What are the implications for research, policy, or practice?Oncologist and clinicians should subject patients treated for head and neck patients to salivary gland scintigraphy during and post treatment in order to assess salivary glands' damage. Information acquired would help to optimize therapy as well as to come up with individualised patient care strategies that would alleviate suffering arising from [AMJ 2018;11(6):335-342] the side effects of therapy.

A number of imaging techniques are useful in the assessment of the salivary glands, namely, plain film radiography, sialography, ultrasonography (USG), radionuclide imaging, magnetic resonance imaging, and computed tomography. One of the most common salivary gland imaging modalities is USG, which helps in obtaining information regarding salivary gland pathologies successfully with good accuracy. USG is the best at differentiating between intra-and extra-glandular masses as well as between cystic and solid lesions, local nodal metastases, and local invasion in case of tumors. USG can demonstrate the presence of an abscess in an acutely inflamed gland, as well as sialoliths, which appear as echogenic densities that exhibit acoustic shadowing. In this review, authors have focused on the role of USG in imaging salivary glands in healthy and diseased states and their sonographic features.

Introduction: There are 2 types of salivary gland tumorsmajor comprising of parotid, submandibular and sublingual glands and numerous minor salivary glands with maximum number in hard palate, soft palate, buccal mucosa, nasopharynx etc. Most salivary glands tumors are benign with less than 20% of them being malignant and are named according to the cell types found under microscopy. Aims and objective of the study was to correlate the clinical diagnosis along with cytology, radiology and histopathological diagnosis and the role of FNAC, USG and CT/MRI in the neoplasms of salivary gland tumors. Material and methods: From all patients attending ENT OPD in our hospital with complaints of salivary gland swellings were evaluated according to the exclusion/inclusion criteria were selected for the study over a span of one year. FNAC is a valuable test but its role is controversial. Results: Ultrasound can delineate location, homegeneity or heterogeneity, shape, vascularity and margins. CT/MRI help in evaluating the extraglandular extension, predict possibility of malignancy based on poorly defined margins. Conclusion: In our study we found that clinical examination, FNAC and USG of the tumor gives us adequate knowledge about nature of disease and should be the ideal first line modality of investigation with CT/MRI as the next to go option for the evaluation and planning of a malignant disease management.
