In Infants And Children

Eleven cases of parotid tumors in children under 16 years of age are considered. The series accounts for 1.6 % of 657 cases of parotid tumor of all ages observed during the Period 1930–1975 and consists of 6 mixed tumors, 2 mucoepidermoid tumors, 2 angiomas, and 1 benign lymphoepithelial lesion. All the patients underwent surgical treatment, 6 radical and 5 limited. The results of treatment point out that mixed tumors require radical parotidectomy. The attitude towards pediatric parotid tumors is discussed.

ntroduction: Salivary tumors represent a heterogeneous group of tumors of diverse location, histological structure and bio logical behavior. The purpose of this study was a retrospective evaluation of surgical treatment of a group of patients with newly dia gnosed benign tumors of the parotid salivary gland operated in the years 2014–2018 at the ENT department of Hospital České Budějovice, a.s. Material and methods: A type of surgery, defi nitive histology, postoperative complications and a number of recurrences were monitored. The data were evaluated by descriptive statistical methods. Results: A total of 190 surgeries with benign histological fi ndings in 182 patients were performed. The most common benign result was Warthin‘s tumor (90 cases, 47.4%), followed by pleomorphic adenoma (66 cases, 34.7%). Uncommon histological types of tumors were dia gnosed in 14 patients (7.4%). Non-tumorous fi ndings were found in 20 cases (10.5%). The most frequently performed procedure in 84 cases (44.2%) was extracapsular extirpation. Transient lesion in the area of innervation of the temporofacial and / or cervicofacial branch of the facial nerve was present in 34 (17.9%) patients. Permanent paresis of some of the branches of the facial nerve was reported in 2 (1.1%) patients. In 12 patients, the postoperative course was complicated by the development of salivary fi stula (6.3%). Pleomorphic adenoma relapsed after extracapsular extirpation in 5 cases (20.0%). After partial parotidectomy, one recurrence of pleomorphic adenoma (3.6%) was recorded. Warthin‘s tumor relapsed after simple extirpation in 4 cases (20.0%). Conclusion: Our evaluation results of the surgical treatment of benign parotid gland tumors lead us to make further eff orts improve the care of our patients. We see reserves mainly in the routine use of ultrasonographic examination with performance FNAC and thus planning a safe and suffi ciently radical operational solution.

Abstract Objective Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) histograms were used to investigate whether their parameters can distinguish between benign and malignant parotid gland tumors and further differentiate tumor subgroups. Materials and methods A total of 117 patients (32 malignant and 85 benign) who had undergone DCE-MRI for pretreatment evaluation were retrospectively included. Histogram parameters including mean, median, entropy, skewness, kurtosis and 10th, 90th percentiles were calculated from time to peak (TTP) (s), wash in rate (WIR) (l/s), wash out rate (WOR) (l/s), and maximum relative enhancement (MRE) (%) mono-exponential models. The Mann–Whitney U test was used to compare the differences between the benign and malignant groups. The diagnostic value of each significant parameter was determined on Receiver operating characteristic (ROC) analysis. Multivariate stepwise logistic regression analysis was used to identify the independent predictors of the different tumor groups. Results For both the benign and malignant groups and the comparisons among the subgroups, the parameters of TTP and MRE showed better performance among the various parameters. WOR can be used as an indicator to distinguish Warthin’s tumors from other tumors. Warthin’s tumors showed significantly lower values on 10th MRE and significantly higher values on skewness TTP and 10th WOR, and the combination of 10th MRE, skewness TTP and 10th WOR showed optimal diagnostic performance (AUC, 0.971) and provided 93.12% sensitivity and 96.70% specificity. After Warthin’s tumors were removed from among the benign tumors, malignant parotid tumors showed significantly lower values on the 10th TTP (AUC, 0.847; sensitivity 90.62%; specificity 69.09%; P < 0.05) and higher values on skewness MRE (AUC, 0.777; sensitivity 71.87%; specificity 76.36%; P < 0.05). Conclusion DCE-MRI histogram parameters, especially TTP and MRE parameters, show promise as effective indicators for identifying and classifying parotid tumors. Entropy TTP and kurtosis MRE were found to be independent differentiating variables for malignant parotid gland tumors. The 10th WOR can be used as an indicator to distinguish Warthin’s tumors from other tumors.

Better Than

The review of 21 cases of mixed tumor of the palate showed that the prognosis, after surgical treatment, is much better than in mixed tumors of the parotid gland. No recurrence was seen in 20 cases, although histologically they often showed great cellularity and pseudo-cylindromatous or muco-epidermoid areas. In the only case which evolved unfavourably, invasive tendency toward the mucous membrane and cylindromatous areas were found.

The Relationship

Background: Accurate imaging of the anatomical relationship between the intraparotid facial nerve branches and parotid tumor can be helpful for surgical planning and effective protection of the facial nerve during surgery. Three-dimensional sheath inked rapid acquisition with refocused echoes imaging (3D-SHINKEI) is a new MRI sequence with a high tissue contrast resolution, which has been used for imaging the peripheral nerves in several organs. Objectives: To evaluate the value of 3D-SHINKEI sequence in representing the intraparotid facial nerve branches and their anatomical relationship with neoplasms of the parotid gland. Patients and Methods: Thirty-six patients with parotid tumors underwent MRI with 3D-SHINKEI and 3D-T2-fast field echo (3D-T2-FFE) sequences in the coronal plane. The contrast-to-noise ratios (CNRs) and signal intensity ratios (SIRs) of the facial nerves in the two sequences were compared. The relationship between the intraparotid facial nerve branches and parotid tumor was also analyzed in 36 patients, and the results were compared with the intraoperative anatomy and postoperative pathological findings. Results: The image quality score of the 3D-SHINKEI sequence for anatomical representation of the intraparotid facial nerve branches was significantly higher than that of the 3D-T2-FFE sequence (Z = −6.197, P < 0.01). The SIRs and CNRs of the facial nerves were significantly higher in the SHINKEI images as compared to the 3D-T2-FFE images (t = 10.772, P < 0.01 and t = 11.586, P < 0.01, respectively). The delineation accuracy of the anatomy of the main trunk of the facial nerve and its first-level branches and their relationship with tumors was significantly higher with the 3D-SHINKEI sequence than with the 3D-T2-FFE sequence (P < 0.01). Besides, the relationship between parotid tumors and the main trunk of the facial nerve and its first-level branches was classified into six types. Conclusion: A high-resolution 3D-SHINKEI sequence could accurately represent the relationship between the intraparotid facial nerve branches and parotid gland neoplasms. It was also found to be more accurate than the 3D-T2-FFE sequence.
