There are risks associated with adenoidectomy surgery, including bleeding, damage to the pharyngo-pharyngeal opening, and other risks, as follows: a. Bleeding: The more common risk is intraoperative and postoperative hemorrhage, which may cause shock in some patients due to the large amount of bleeding. Eustachian tube pharyngeal port injury: The pharyngeal tube pharyngeal port may be damaged during surgery, resulting in pharyngeal tube obstruction or secretory otitis media. Other risks: some patients may develop nasopharyngeal adhesions, as well as posterior nostril stenosis and posterior nostril atresia, and some patients may cause nasal dryness, and some patients may damage the prevertebral fascia. There are individual differences in the specific surgical risks, but in general, the technology for adenoidectomy is relatively mature, and it is usually done as a minimally invasive nasal endoscopic adenoidectomy. Most patients can recover successfully after surgery, and the probability of complications related to surgical risks is relatively low.
