HIFU Effectiveness 4

HIFU Effectiveness 4
HIFU using the following probes: 4 MHz, 4.5-mm focal depth; 7 MHz, 4.5-mm focal depth; and 7 MHz, 3.0-mm focal depth. We used hand pieces that delivered energy at 7.5 MHz and focal depths of 3.0 and 4.5 mm. Topical lidocaine/prilocaine cream was applied under an occlusive dressing
HIFU for 60 minutes. In three patients, we used a nerve block of the supraorbital, supratrochlear, intraorbital, and mental nerves. After cleaning the face, a layer of ultrasound gel was applied to the skin. Each probe delivered a set of pulses in a linear array at 1-cm intervals.
HIFU From 400 to 500 shots were delivered according to the size of the face. who were not directly involved in the treatments. They divided the face into seven areas (supraorbital, zygomatic, infraorbital, perioral, cheek, preauricular, and jawline, excluding the nose and periorbital areas).
To assess the severity of facial wrinkles and skin laxity, we modified the eight-point photographic scale suggested by Chung et al.12. Each facial area was evaluated before treatment and after 3 and 6 months by using the following scale: 0, none; 1, mild; 2, mild/moderate; 3, moderate; and 4, severe.
The overall clinical improvement was also assessed. In addition, we conducted a survey to assess patient satisfaction and adverse effects. Each patient scored their satisfaction in each area of their faces, and also scored their overall satisfaction with their improvement after treatment
