Dear Editor I have recently read the article of Ayyildiz et al. on Morphometric examination of the styloid process by 3D‑CT in patients with Eagle syndrome.The article focuses the attention on the importance of a correct imaging diagnosis in order to better clarify styloid relationship with other structures even in the presence of a styloid process of normal length. Lateral and medial deviations can occur, in fact, in a normal styloid process but, at the same time, can cause compression of vessels and nerves. The article, moreover, underlines the importance of a correct diagnosis focusing not only on the length of styloid process (which could be normal), but even on the direct relationship between styloid and the vascular and neural near structures even in the presence of a process of normal length and C1 Transverse Process. Our recent experience focuses the attention on the “dynamic” relationship between SP and near structures. In particular, above all in the vascular variant, neurological signs seem to be often infuenced by the position of head and neck, varying in the same patient from a position to another. As a consequence of this strong infuence of head and neck position we think that, in the case of a suspected ES, a standard “static” tool could not be suffcient to better clarify the relationship between styloid and other structures. In other words, in case of suspected ES imaging tool like MRI and ultrasonography of the head and neck region should be taken in diferent position of the head, being the structures involved in such syndrome conditioned by the diferent positions of the entire head and neck region. Hence, we usually perform a double tool including MRI and Ultrasonography in the same standardized fve positions of the head: rest position, maximum extension, maximum fexion of the head, maximum right and maximum left rotation. We do think that this method, in case of a suspected vascular Eagle syndrome, may help in the diferential diagnosis to not misdiagnose ES which could be underestimated in case of a static tool imaging acquisition.

Abstract

Dear Editor I have recently read the article of Ayyildiz et al. on Morphometric examination of the styloid process by 3D‑CT in patients with Eagle syndrome.The article focuses the attention on the importance of a correct imaging diagnosis in order to better clarify styloid relationship with other structures even in the presence of a styloid process of normal length. Lateral and medial deviations can occur, in fact, in a normal styloid process but, at the same time, can cause compression of vessels and nerves. The article, moreover, underlines the importance of a correct diagnosis focusing not only on the length of styloid process (which could be normal), but even on the direct relationship between styloid and the vascular and neural near structures even in the presence of a process of normal length and C1 Transverse Process. Our recent experience focuses the attention on the “dynamic” relationship between SP and near structures. In particular, above all in the vascular variant, neurological signs seem to be often infuenced by the position of head and neck, varying in the same patient from a position to another. As a consequence of this strong infuence of head and neck position we think that, in the case of a suspected ES, a standard “static” tool could not be suffcient to better clarify the relationship between styloid and other structures. In other words, in case of suspected ES imaging tool like MRI and ultrasonography of the head and neck region should be taken in diferent position of the head, being the structures involved in such syndrome conditioned by the diferent positions of the entire head and neck region. Hence, we usually perform a double tool including MRI and Ultrasonography in the same standardized fve positions of the head: rest position, maximum extension, maximum fexion of the head, maximum right and maximum left rotation. We do think that this method, in case of a suspected vascular Eagle syndrome, may help in the diferential diagnosis to not misdiagnose ES which could be underestimated in case of a static tool imaging acquisition.
