Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
A variety of analgesic regimens have been implemented to alleviate post-tonsillectomy pain, however; no consensus on the ideal analgesic regimen has been yet identified.
The Ultrasound (US)-guided glossopharyngeal nerve (GPN) block has been acknowledged as a feasible option for providing perioperative analgesia in tonsillectomy patients. It blocks sensory impulses from the posterior third of the tongue, palatine tonsil, and mucous membranes of the mouth and pharynx. Conventional techniques for blocking the GPN carry the risk of vascular puncture, inadvertent block of closely adjacent other cranial nerves, with increased probability of local anesthetic toxicity and even upper airway obstruction. Recently, a novel, safe, and reproducible US-guided GPN block technique has been introduced by Azman et al, which would block the GPN distally, in the tissue plane just next to the pharyngeal wall and relatively far from high risk nearby structures.

Study Groups
Review each arm or cohort in the study, along with the interventions and objectives associated with them.
Group I (glossopharyngeal nerve block group)
bilateral ultrasound guided GPN block will be performed after induction of anesthesia and pre incisional by an experienced anesthesiologist
bilateral ultrasound guided GPN block
a linear high frequency ultrasound probe will be initially positioned over the hyoid bone in the transverse plane, then the probe will be rotated to keep in line with the mandibular angle and the pharyngeal wall is identified by US. Using an in plane approach, a 22 G ,5 cm needle will be advanced till it reaches just superficial to the pharyngeal wall and 2.2 ml of 0.25% bupivacaine will be injected.
Group II(Control group)
general anesthesia alone (no block)
No interventions assigned to this group
