“…CT detected abscesses with 100% accuracy in all patients with a clinical suspicion of neck mass of infectious aetiology. The most common space with abscess formation was PMS, comprising 26% of all cases, followed by PPS in which 20% of total cases of abscesses were seen, similarly to previous studies [17,18] which affirmed that the most often infected neck space was the peritonsillar space (42.9% of cases). In the present study, out of 10 parotid gland tumours, 6 were pleomorphic adenomas, 1 was benign lipomatosis and 3 were malignant tumours.…”

SummaryBackgroundSuprahyoid neck lesions are difficult to assess only by means of clinical inspection and therefore imaging techniques are required to precisely evaluate suprahyoid neck spaces. The aim of this study was to evaluate the distinctive role of computed tomography in the assessment of anatomical source and pathological type of masses involving the suprahyoid neck spaces.Material/MethodsSixty patients presenting with suprahyoid neck masses underwent computed tomography of the neck. The CT findings were correlated with histopathological findings and a final diagnosis was made.ResultsOverall, male preponderance was seen except in the case of parotid space lesions where female predominance was seen. The most common aetiology was squamous cell carcinoma and the majority of cases (30%) were seen in patients aged 41–50 years. The majority of lesions were found in the pharyngeal mucosal space (n=16) with squamous cell carcinoma being the most common pathology. In the parotid space, pleomorphic adenoma and in the prestyloid parapharyngeal space, squamous cell carcinoma were the most common lesions, respectively. In the retropharyngeal space, an equal incidence of malignant and inflammatory aetiologies was seen. Abscesses were the most common lesions in the prevertebral space. The pleomorphic adenoma was the most common benign tumour and was also the second most common tumour in the suprahyoid neck spaces. CT had an excellent correlation with histopathological findings with sensitivity of 96.4%, specificity of 100%, positive predictive value of 100% and a negative predictive value of 91.67%.ConclusionsComputed tomography definitely has a major role to play in the evaluation of suprahyoid neck masses as it has an excellent correlation with post-operative histopathological diagnosis.

“…In the literature, imaging methods such as lateral neck radiography, computed tomography, and magnetic resonance imaging were used for the assessment of palatine tonsil volume. [5][6][7] Lateral neck radiography is not very effective, as it is 2-dimensional. Although computed tomography and magnetic resonance imaging have been reported to have successful results, especially in the diagnosis of peritonsillar abscesses, the use of those methods is limited because of radiation exposure, sedation necessity in children, and high costs.…”

Objectives To investigate the success of ultrasonography (USG) in the objective measurement of palatin tonsil volume in both children and adults and to compare those results with clinical findings. Methods Eighty‐five patients, who were scheduled to undergo tonsillectomy with the indications of recurrent tonsillitis and obstructive sleep apnea syndrome, were included in the study. The tonsil grades of the patients were recorded according to the Friedman tonsil grading. The tonsil size and volume were measured with transcervical USG. After tonsillectomy, the volumes of the tonsils were calculated by the displacement method. The correlation between the obtained data was evaluated. In all analyses, P < .05 was accepted as a statistical level of significance. Results Fifty children and 35 adults were included in the study. In children, the mean actual volume ± SD of 100 tonsils was measured as 3.5 ± 1.45 mL, and the USG volume was 3.67 ± 1.59 mL; a high correlation was found between both methods (r = 0.842; P < .05). In adults, the mean actual volume of 70 tonsils was measured as 5.15 ± 2.25 mL, and the USG volume was 5.71 ± 2.98 mL; a moderate correlation was found between the methods (r = 0.589; P < .05). In children, a moderate correlation was found between the Friedman grading and the USG (r = 0.532; P < .05), and actual (r = 0.549; P < .05) tonsil volumes. In adults, a low correlation was found between the Friedman grading and the USG (r = 0.363; P < .05) and actual (r = 0.384; P < .05) tonsil volumes. Conclusions Ultrasonography is a useful, accessible, and noninvasive imaging method for objective measurement of tonsil volume in adults and children.

“…Previous reports have indicated that CT and MRI can also be used to evaluate the tonsils . In particular, CT has been reported to be useful for evaluating the peritonsillar abscess and the extent of inflammation, and has the advantage of allowing for the mediastinum and retropharyngeal space to be viewed at the same time . However, children may require sedation, and they are exposed to radiation.…”

“…The use of imaging techniques such as computed tomography (CT) and magnetic resonance imaging (MRI) have been reported to be useful for the evaluation of peritonsillar abscesses and the overall volume of the tonsils; however, these techniques have a number of limitations, such as a requirement of sedation, exposure to radiation, and/or a high cost. Recently, the use of ultrasound for evaluating the tonsils has been reported, which represents a less expensive, more portable, and more rapidly available technique with better tissue resolution.…”
