“…[1][2][3] Because it is performed without open surgery, the tissue to be treated or being treated cannot be seen by the naked eye. Therefore, to ensure both the efficacy and safety of the treatment, a noninvasive imaging modality is required to be combined to aim and monitor the treatment.…”

Acoustic cavitation bubbles are known to enhance the heating effect in high-intensity focused ultrasound (HIFU) treatment. The detection of cavitation bubbles with high sensitivity and selectivity is required to predict the therapeutic and side effects of cavitation, and ensure the efficacy and safety of the treatment. A pulse inversion (PI) technique has been widely used for imaging microbubbles through enhancing the second-harmonic component of echo signals. However, it has difficulty in separating the nonlinear response of microbubbles from that due to nonlinear propagation. In this study, a triplet pulse (3P) method was investigated to specifically image cavitation bubbles by extracting the 1.5th fractional harmonic component. The proposed 3P method depicted cavitation bubbles with a contrast ratio significantly higher than those in conventional imaging methods with and without PI. The results suggest that the 3P method is effective for specifically detecting microbubbles in cavitation-enhanced HIFU treatment.

“…Traditional ultrasonic surgery has been used in dental practice since the 1940s (Lynn et al, 1942). In the following decades, it has been applied to the following more challenging oral surgical procedures: alveolar ridge expansion (Blus and Szmukler-Moncler, 2006;Schlee et al, 2006) exposure of impacted canines (Grenga and Bovi, 2004), lateralisation of the inferior alveolar nerve (Bovi, 2005), sinus lifts for the placement of implants (Eggers et al, 2004;Stübinger et al, 2005;Barone et al, 2008), endodontic and periodontal surgery (Vercellotti and Pollack, 2006;Peñarrocha et al, 2007), and to harvest autologous bone grafts (Sohn et al, 2007).…”

a b s t r a c tPurpose: Investigators have hypothesised that piezoelectric surgical device could permanently replace traditional saws in conventional orthognathic surgery. Methods: Twelve consecutive patients who underwent bimaxillary procedures were involved in the study. In six patients the right maxillary and mandible osteotomies were performed using traditional saw, whilst the left osteotomies by piezoosteotomy; in the remaining six patients, the surgical procedures were reversed. Intraoperative blood loss, procedure duration time, incision precision, postoperative swelling and haematoma, and nerve impairment were evaluated to compare the outcomes and costs of these two procedures. Results: Compare to traditional mechanical surgery, piezoosteotomy showed a significant intraoperative blood loss reduction of 25% (p ¼ 0.0367), but the mean surgical procedure duration was longer by 35% (p ¼ 0.0018). Moreover, the use of piezoosteotomy for mandible procedure required more time than for the maxillary surgery (p ¼ 0.0003). There was a lower incidence of postoperative haematoma and swelling following piezoosteotomy, and a statistically significant reduction in postoperative nerve impairment (p ¼ 0.003). Conclusions: We believe that piezoelectric device allows surgeons to achieve better results compared to a traditional surgical saw, especially in terms of intraoperative blood loss, postoperative swelling and nerve impairment. This device represents a less aggressive and safer method to perform invasive surgical procedures such as a Le Fort I osteotomy. However, we recommend the use of traditional saw in mandible surgery because it provides more foreseeable outcomes and well-controlled osteotomy. Further studies are needed to analyse whether piezoosteotomy could prevent relapse and promote bony union in larger advancements. Ó

“…Since its introduction in dental practice (Lynn et al, 1942), it has become one of the most widely adopted techniques for performing osteotomies in orthognathic surgery, distraction osteogenesis, and dentoalveolar surgery. Currently, its use has spread to other surgical specialties, such as neurosurgery and otorhinolaryngology (Gleizal et al, 2007).…”
