“…Interestingly, lateral cephalometry may not be the only imaging modality that reveals these relevant changes. As Kuroda et al 8 have shown, hyoid bone position on lateral cephalometric radiography is consistent with hyoid bone position on panoramic radiography. Panoramic radiography is commonly used in dental treatment and offers several advantages, including reduced patient stress and the ability to image not only all of the teeth but also the maxillary sinus and the temporomandibular joint.…”

The purpose of this study was to establish a screening method for dysphagia using panoramic radiography. Seventy patients who had undergone panoramic radiography and videofluorographic swallowing study VF were selected. Exclusion criteria were surgery related to tumors, jaw deformity, and poor-quality panoramic radiograph images. Patients were diagnosed with dysphagia based on VF findings and accordingly categorized into Dysphagia or Dysphagia groups. The control group consisted of 129 individuals who had undergone panoramic radiography for dental treatment. Exclusion criteria were the same as in the Dysphagia and Dysphagia groups. Two maxillofacial radiologists assessed the vertical and horizontal position of the hyoid bone and measured the distance from the tongue to the palate. The vertical hyoid bone position was significantly lower in the Dysphagia group than in the control group. The distance from the tongue to the palate was significantly shorter in the control group, measuring 8.5 5.9 mm as compared to 15.0 9.5 in the Dysphagia group and 14.9 10.0 in the Dysphagia group. At least 77 of patients were diagnosed with dysphagia or suspected of dysphagia because the hyoid body was below the mandibular line on panoramic radiography. Panoramic radiography may be a useful tool for predicting the risk of dysphagia as it reveals the vertical hyoid bone position and the distance from the tongue to the palate.

“…Oral frailty is a risk factor for physical frailty, and is related to quality of life. In previous studies [1,2], we suggested that patients with dysphagia have a lower position of the hyoid bone on panoramic radiographs. However, this anatomical structure did not focus on the dental treatment.…”

Background: Oral frailty is associated with systemic frailty. The vertical position of the hyoid bone is important when considering the risk of dysphagia. However, dentists usually do not focus on this position. Purpose: To create an AI model for detection of the position of the vertical hyoid bone. Methods: In this study, 1830 hyoid bone images from 915 panoramic radiographs were used for AI learning. The position of the hyoid bone was classified into six types (Types 0, 1, 2, 3, 4, and 5) based on the same criteria as in our previous study. Plan 1 learned all types. In Plan 2, the five types other than Type 0 were learned. To reduce the number of groupings, three classes were formed using combinations of two types in each class. Plan 3 was used for learning all three classes, and Plan 4 was used for learning the two classes other than Class A (Types 0 and 1). Precision, recall, f-values, accuracy, and areas under the precision–recall curves (PR-AUCs) were calculated and comparatively evaluated. Results: Plan 4 showed the highest accuracy and PR-AUC values, of 0.93 and 0.97, respectively. Conclusions: By reducing the number of classes and not learning cases in which the anatomical structure was partially invisible, the vertical hyoid bone was correctly detected.

“…The advantage of radiographic images is their ability to provide an overview of the maxillofacial area and not only the teeth. Kuroda et al [7] suggested that there is a relationship between the hyoid bone position on lateral cephalometric radiographs and panoramic radiographs. Additionally, Ito et al [8] suggested that the hyoid bone position on panoramic radiographs is related to dysphagia.…”

Background: Dysphagia relates to quality of life; this disorder is related to the difficulties of dental treatment. Purpose: To detect radiographic signs of dysphagia by using panoramic radiograph with an AI system. Methods: Seventy-seven patients who underwent a panoramic radiograph and a videofluorographic swallowing study were analyzed. Age, gender, the number of remaining teeth, the distance between the tongue and the palate, the vertical and horizontal hyoid bone position, and the width of the tongue were analyzed. Logistic regression analysis was used. For the statistically significant factors, the cutoff level was determined. The cutoff level was determined by using analysis of the receiver operations characteristic (ROC) curve and the Youden Index. Results: A significant relationship with presence of dysphagia was only observed for the vertical hyoid bone position. The area under the curve (AUC) was 0.72. The cutoff level decided for the hyoid bone was observed to be lower than the mandibular border line. Conclusions: In cases where the hyoid bone is lower than the mandibular border line on a panoramic radiograph, it suggests the risk of dysphagia would be high. We will create an AI model for the detection of the risk of dysphagia by using the assessment of vertical hyoid bone position.
