Modified Thoracoabdominal Nerves Block Through Perichondrial Approach: a New Strategy With a Wide Range of Utilization in Laparoscopic Gynecological Surgeries.

A high frequency (6-12 MHz) US linear probe was placed in the sagittal plane on the 10 th costal margin in the midline. The probe was then angulated deeply to visualize the lower surface of the costal cartilage. Via in plane technique, a 21 gauge Tuohy needle was inserted cranially between the lower fascia of the costal cartilage and upper fascia of the transversus abdominis muscle by moving the needle tip towards the posterior aspect of the 10 th costal cartilage and 20 mL bupivacaine (0.25 %) was injected.
