Abstract:
Objective To investigate the CT features of the invasion of sublingual space by malignant oropharyngeal tumors in order to provide more accurate information for clinical treatment. Methods Fifty-eight cases of pathologically proven malignant oropharyngeal tumors were collected and retrospectively analyzed. Results Among all the cases, invasion of sublingual space by malignant oropharyngeal tumors could be seen in 14 cases, of which, 7 cases got access to sublingual space through tongue base, 3 cases through parapharyngeal space, 2 cases through pterygomandibular raphe, 2 cases through uncertain routes. Invasion of sublingual space manifested on CT scan as obliteration of fat plane in sublingual space and involvement of the sublingual vessels in the space. Conclusion Malignant oropharyngeal tumors can invade the adjacent sublingual space via tongue base, pterygomandibular raphe, and parapharyngeal space. The invasion of sublingual space by malignant oropharyngeal tumors manifests in CT as effacement of sublingual fat plane and envelopment of hyoid artery.
