A tonsillectomy and adenoidectomy is a surgical procedure that involves the removal of the tonsils and adenoids, which are lymphoid tissues located in the throat and nasopharynx, respectively. This procedure is typically indicated for patients aged 12 years or older who experience recurrent throat infections, obstructive sleep apnea, or other related conditions. During the surgery, a mouth prop is utilized to keep the mouth open, allowing the surgeon clear access to the tonsils. The tonsils are grasped with clamps to provide traction, facilitating the dissection process. Various techniques may be employed for the dissection, including the use of scissors, curettes, cautery, radiofrequency, laser ablation, or harmonic scalpels. The standard dissection technique involves incising the mucosa with a sickle knife, starting at the superior pole of the tonsil and moving inferiorly through the connective tissue. Once the tonsil is fully dissected, it is removed using a snare technique. After the tonsillectomy, the surgical site is carefully inspected to ensure that any remaining tonsil tissue is excised, and bleeding is managed through pressure, sutures, or cautery. The adenoidectomy is performed subsequently, utilizing instruments such as an adenotome or adenoid curette, or by vaporization with a laser. The procedure is designed to alleviate symptoms associated with enlarged tonsils and adenoids, improving the patient's quality of life.
