Ultrasonographic evaluation of mandibular ameloblastoma: a preliminary observation

Ultrasound evaluation of intra-osseous cavity: A preliminary study in pig mandibles

“…Our results are in agreement with the reports by other authors, who state that ultrasound examination of intra-osseous lesions is possible. 1,2,4,5,7-9,13, 14 We emphasize that the bone cortex must be thin for intraosseous examination using ultrasound, which was confirmed by statistical analysis in the present study. This is generally observed in maxillofacial osseous defects as the development of lesions causes internal (intra-osseous) expansion and reduces the cortical bone, allowing ultrasound waves to pass through.…”

“…However, they could be observed with low (14), moderate (6), and high (6) degrees of difficulty in other images. Table 1 shows the distribution of answers given by dental radiologists and physician ultrasonographers to Question 1.…”

“…This is generally observed in maxillofacial osseous defects as the development of lesions causes internal (intra-osseous) expansion and reduces the cortical bone, allowing ultrasound waves to pass through. 2,14 However, the wave passing through is blocked at regions which are still integral or thicker. Lauria et al, 2 faced problems in obtaining ultrasound images in cases of keratocystic odontogenic tumors, which develops mainly in the mesio-distal direction.…”

“…18 The possibility of examining the lesion's content is admittedly one of the advantages offered by ultrasound, both in soft and hard tissue examination. 1,2,4,5,9,14,19 The possibility of using Doppler for real-time evaluation of the degree of lesion vascularization is another differential feature of ultrasound as it allows alterations to be evaluated depending on their degree of activity/aggressiveness. 1,14 Moreover, Rajendran and Sundaresan 20 described that the use of ultrasound allows verifying whether the blood flow is arterial or venous.…”
