Surgically treated pediatric tongue masses: A 20 Year review

OBJECTIVE

Pediatric tongue lesions represent a rare, diverse group of pathologies related to congenital malformations, inflammatory changes, and neoplastic masses. We present the largest-to-date series of pediatric tongue lesions managed surgically.

SETTING

Charts of all pediatric patients with a tongue lesion surgically treated at a regional children's hospital from February 1st, 1997 to August 30th, 2019 were reviewed.

METHODS

After obtaining institutional review board approval, a retrospective review was completed of all pediatric patients with a tongue lesion surgically treated at a regional children's hospital from February 1st, 1997 through August 30th, 2019. Charts were evaluated for patient demographics as well as symptoms at presentation, surgical details, pathologic evaluation of the lesion, and rates of recurrence. Categorical variables were compared between various groups using Chi-square and/or Fisher's exact tests. Univariate and multivariable logistic regression analysis was performed unadjusted and adjusted to further explore these relationships.

RESULTS

159 patients were included in the study with ages distributed relatively even across infants (27.7%), children 1-5 years (27.7%), 6-10 years (23.3%), and greater than 10 years of age (21.4%). Patient/family reported race/ethnic background was most commonly Caucasian (34.8%) or Hispanic/Latino/Spanish Origin (34.0%) followed by Black or African American (21.3%). The most commonly reported symptoms were pain (23.3%), difficulty with oral intake (12.6%), bleeding (11.3%), and respiratory distress (11%). Patients with lesions of the base of tongue were significantly more likely to present with respiratory distress or difficulty with oral intake (p < 0.001). The likelihood of recurrence was observed to be higher with lesions managed in infancy (OR 3.85, CI 1.47-10.0, p = 0.005), those greater than 2 cm (OR 3.45, CI 1.34-8.71, p = 0.009), or with laser (OR 4.52, CI 1.25-15.00), p = 0.015).

CONCLUSION

Pediatric patients with tongue lesions may present with a wide array of symptoms. Base of tongue lesions should be managed carefully as they are most likely to create barriers to the airway and oral intake. Larger lesions and those managed in infancy are at increased risk for recurrence.

Role of MRI in Evaluation of Tongue and Hypopharyngeal Lesions

Tongue is a complex, principally muscular structure extending from oral cavity to oropharynx. Hypopharynx extends from the level of hyoid bone and to the level of inferior margin of cricoid cartilage and is divided into pyriform sinus, posterior cricoid region and posterior pharyngeal wall. Lesions that can affect the tongue and hypopharynx include neoplastic, congenital, vascular and infectious etiologies. Imaging provides crucial details for diagnosis and the appropriate management of these lesions. To evaluate the role of MRI in characterisation of benign and malignant lesions of tongue, malignant lesions of hypopharynx and staging the neoplastic lesions. The study was performed on 60 patients suspected of tongue and hypopharyngeal lesions in Dr Ram Manohar Lohia Hospital, New Delhi from 1st January 2021 to 31st May 2022. The study was done on SEIMENS skyra MRI scanner. Radiological characteristics, clinical features were studied and statistical inference was interrogated. Out of 60 patients, 32 were of tongue cancer, 10 of base of tongue cancer, 8 of hypopharyngeal cancer, 8 of hemangioma tongue and 2 of thyroglossal cyst. The mean age of our study population was 42.87 years. The qualitative analysis between diffusion restriction and histopathological examination shows a strong and substantial agreement between the two variables and a p value of 0.0014. The overall diagnostic accuracy of MRI was 85.5% and for CT was 82.5%. MRI plays an important role in differentiation of benign from malignant lesions of tongue and hypopharynx and staging of the malignant lesions. The correlation between MRI and CT findings of malignant lesions of tongue and hypopharynx indicated that both CECT and MRI have high diagnostic accuracy in diagnosing and staging but MRI is better for T and N staging of the malignant lesions with a diagnostic accuracy of 85.5% which was higher than the diagnostic accuracy of CT (82.5%). Thus, in conclusion MRI has a remarkable role in characterization and staging of benign and malignant lesions of tongue and hypopharynx.

Artificial intelligence in tongue diagnosis: classification of tongue lesions and normal tongue images using deep convolutional neural network

OBJECTIVE

This study aims to classify tongue lesion types using tongue images utilizing Deep Convolutional Neural Networks (DCNNs).

METHODS

A dataset consisting of five classes, four tongue lesion classes (coated, geographical, fissured tongue, and median rhomboid glossitis), and one healthy/normal tongue class, was constructed using tongue images of 623 patients who were admitted to our clinic. Classification performance was evaluated on VGG19, ResNet50, ResNet101, and GoogLeNet networks using fusion based majority voting (FBMV) approach for the first time in the literature.

RESULTS

In the binary classification problem (normal vs. tongue lesion), the highest classification accuracy performance of 93,53% was achieved utilizing ResNet101, and this rate was increased to 95,15% with the application of the FBMV approach. In the five-class classification problem of tongue lesion types, the VGG19 network yielded the best accuracy rate of 83.93%, and the fusion approach improved this rate to 88.76%.

CONCLUSION

The obtained test results showed that tongue lesions could be identified with a high accuracy by applying DCNNs. Further improvement of these results has the potential for the use of the proposed method in clinic applications.
