Ultrasound-Guided Suprazygomatic Maxillary Nerve Block as A Part of Multimodal Analgesic Regimens

August 21, 2021 updated by: Amr Samir Wahdan, Cairo University

The Effect of Ultrasound-Guided Suprazygomatic Maxillary Nerve Block for Minimize the Post-operative Pain in Tonsillectomy Surgery

Inadequate peri-operative analgesia may contribute to an increased risk of bleeding, suture dehiscence and unacceptable surgical outcomes. Moreover, these patients are at high risk of postoperative airway obstruction and respiratory failure.

Opioids may contribute to these complications. Appropriate use of regional anaesthesia may mitigate or eliminate many of these concerns. The maxillary nerve is responsible for the sensory innervation of the midface, including the hard and soft palates, upper jaw, upper dental arch and upper lip.Recently, the successful use of maxillary nerve block by the suprazygomatic approach has been reported in children undergoing cleft palate surgery. However, the use of this block has not been described in large series of patients, and the effectiveness of the suprazygomatic approach has not been evaluated in patients undergoing tonsillectomy .
