Adenoidectomy is the surgical removal of the adenoid glands—lymphoid tissues located high in the throat behind the nose. These glands form part of the immune system in early childhood by trapping bacteria and viruses that enter through the nasal passages.
What is adenoidectomy procedure?
An adenoidectomy is a surgical procedure to remove the adenoid glands—lymphoid tissues located high in the throat behind the nasal cavity—when they become chronically enlarged or infected. Performed under general anesthesia through the oral route, the child’s mouth is held open with a retractor while the surgeon excises the adenoids using blind curettage, electrocautery, coblation, or microdebrider techniques under endoscopic guidance to ensure precision and minimize bleeding. Preoperative evaluation often includes a clinical exam supplemented by lateral nasopharyngeal radiographs or nasal endoscopy in cooperative children to assess adenoid hypertrophy and eustachian tube function. The operation usually lasts 15–30 minutes and is offered as a day case, allowing discharge once vital signs stabilize and the child tolerates oral fluids and pain is controlled. Hemostasis is achieved with targeted cautery or topical agents, and dissolvable sutures or natural mucosal apposition reduce postoperative bleeding risk. Recovery protocols emphasize adequate hydration, a soft diet, and avoidance of strenuous activity for about one week to promote healing. While complications such as bleeding, infection, or anesthetic reactions are uncommon with meticulous perioperative care, adenoidectomy reliably restores nasal airflow, alleviates eustachian tube–related ear disease, and improves sleep quality in young patients.
What does an adenoidectomy treat?
An adenoidectomy removes the adenoid glands when they become chronically enlarged or infected and begin to obstruct the upper airway and eustachian tube openings. Primarily performed in children between ages one and seven, it treats nasal obstruction that manifests as persistent mouth breathing, pronounced snoring, and obstructive sleep apnea—conditions that disrupt sleep quality and can lead to daytime fatigue and behavioral issues. By excising hypertrophic adenoids, the procedure restores nasopharyngeal patency and alleviates nasal congestion, enabling normal nasal breathing and reducing the risk of craniofacial abnormalities linked to chronic mouth breathing. Adenoidectomy also addresses eustachian tube dysfunction responsible for recurrent otitis media with effusion (“glue ear”) and chronic middle ear infections; removal of the adenoids improves middle ear ventilation, decreases infection frequency, and mitigates conductive hearing loss in young patients. In children with stubborn sinusitis unresponsive to antibiotics, adenoidectomy eliminates a bacterial reservoir in the nasopharynx, enhancing sinonasal drainage and reducing infection recurrence. Often combined with tonsillectomy or grommet insertion, it delivers comprehensive relief from upper airway obstruction and ear disease. Ultimately, adenoidectomy promotes better breathing, hearing, sleep quality, and overall quality of life in pediatric patients.
What happens during an adenoidectomy?
During an adenoidectomy, patients undergo a carefully orchestrated sequence beginning with preoperative assessment and fasting according to hospital guidelines. Once in the operating room, general anesthesia is administered, and the child’s mouth is held open with a specialized retractor to grant unobstructed access to the nasopharynx. The surgeon then excises the adenoid tissue using one of several techniques—blind curettage with a curette, electrocautery to both remove tissue and seal blood vessels, coblation employing radiofrequency energy, or microdebrider excision under endoscopic visualization for enhanced precision. Hemostasis is meticulously achieved through targeted cauterization or topical hemostatic agents, and the adenoid bed is left to heal by secondary intention, often obviating the need for sutures. The procedure typically lasts between 15 and 30 minutes, after which patients are transferred to a recovery area for monitoring of vital signs, pain management, and hydration. Once the child is alert, tolerates clear fluids, and demonstrates stable breathing without significant bleeding, discharge home on the same day is customary. Postoperative care includes a soft diet, adequate oral fluid intake, analgesia with acetaminophen or ibuprofen, and activity restrictions for about one week to support healing and minimize bleeding risk. Follow-up ensures resolution of nasal obstruction, improvement in ear ventilation, and overall recovery.
What are the benefits of having adenoids removed?
Removal of the adenoids offers multiple benefits by restoring normal airflow through the nasal passages, which alleviates chronic mouth breathing, markedly reduces snoring, and often resolves mild to moderate obstructive sleep apnea, leading to better sleep quality and daytime alertness in children. By excising hypertrophic or infected adenoid tissue that can block the eustachian tube openings, adenoidectomy significantly decreases the frequency of otitis media with effusion (“glue ear”) and recurrent middle ear infections, thereby improving hearing thresholds and reducing reliance on antibiotics or tympanostomy tubes. Eliminating this reservoir of pathogenic bacteria in the nasopharynx also diminishes episodes of chronic rhinosinusitis and persistent nasal congestion, which translates into fewer antibiotic courses and doctor visits for sinus infections. Beyond infection control, normalized nasal breathing supports healthy craniofacial growth patterns by encouraging proper tongue posture and jaw development, potentially mitigating malocclusion associated with long-term mouth breathing. Moreover, because adenoidectomy is a relatively quick, low-risk outpatient procedure with rare complications, most children resume a regular diet and activities within a week, enjoying immediate relief of nasal obstruction and ear symptoms and an overall enhancement in quality of life.
What are the risks of an adenoidectomy?
While adenoidectomy is generally considered a safe, outpatient procedure, it carries several potential risks that caregivers should understand. Bleeding is the most common complication, occurring intraoperatively or within the first two weeks post-surgery; although rare, significant hemorrhage may necessitate cauterization or, in extreme cases, blood transfusion. Anesthetic reactions—ranging from mild allergic responses to more serious airway events like laryngospasm, bronchospasm, or respiratory distress—are uncommon but can lead to postoperative admission for monitoring and support. Surgical site infection is rare but may prolong recovery, contributing to pain, fever, or drainage; prophylactic measures and sterile technique minimize this risk. Velopharyngeal insufficiency can manifest as nasal regurgitation of liquids or hypernasal speech, typically transient but occasionally requiring speech therapy or further intervention. Adenoid regrowth, though infrequent, may cause recurrence of nasal obstruction or ear disease and require revision surgery. Additional risks include postoperative dehydration from throat discomfort, nausea, or vomiting, as well as pain that sometimes leads to delayed oral intake and readmission for intravenous fluids or analgesia. Very rarely, adjacent structures such as teeth, the soft palate, or Eustachian tube orifices can be inadvertently injured. By recognizing these complications, surgical teams can implement vigilant perioperative care to detect and manage adverse events promptly.
Conclusion
Removal of the adenoids stands as a cornerstone in pediatric airway and ear care, offering swift relief from chronic nasal obstruction, recurrent ear infections, and sleep-disordered breathing. By excising hypertrophic lymphoid tissue, adenoidectomy restores natural nasal airflow, improves middle ear ventilation, and breaks the cycle of infection that can lead to hearing loss and behavioral issues. Its outpatient setting, brief operative time, and low complication rates allow most children to return to normal diets and activities within days, minimizing disruption to family life. When combined with modern techniques—such as endoscopic guidance, coblation, and precise hemostasis—the procedure delivers consistent outcomes with rare adverse events. Looking ahead, ongoing refinements in imaging, intraoperative technology, and postoperative care promise to further enhance safety and efficacy.
