The tonsils are two masses of tissue found on either side of the back of the throat. The adenoids are located high in the throat behind the nose and roof of the mouth. Together they form part of the ring of glandular tissue at the back of the throat. The tonsils and adenoids assist the body in defense against infection by "sampling" entering bacteria and viruses and becoming infected themselves. They then help form antibodies to resist and fight future infections. However, the tonsils and adenoids often become susceptible to recurrent bacterial infections and can even trigger airway obstruction.
Bacterial infections of the adenoids can be treated with various antibiotics. Patients can also help relieve symptoms by getting rest and drinking plenty of liquids. Surgical removal is considered when conditions are resistant to medical therapy or frequently recur.
An adenoidectomy is the surgical removal of the adenoids, glands located behind the nose above the roof of the mouth. The function of the adenoids is to help fight ear, nose and throat infections by screening bacteria as they enter the body. At times, however, the adenoids themselves may become chronically infected and require removal; this condition is known as adenoiditis.
The majority of adenoidectomies are performed in children, frequently in combination with tonsillectomies. In such cases, the procedure is called an adenotonsillectomy. The adenoids usually shrink by adolescence, so adults rarely undergo the procedure.
Diagnosis of Diseased Adenoids
While the tonsils can be seen by physical examination, the adenoids cannot. However, diseased adenoids have certain telltale signs, including yellow or white spots near the tonsils or tongue, swollen lymph nodes, or irritated red spots in the mouth, that enable their diagnosis. The adenoids themselves may be seen through the use of a special mirror in the mouth, or through a tube called an endoscope, which is inserted through the nose. Other tests to diagnose problems with the adenoids may include sleep studies or X-rays of the area.
Reasons for an Adenoidectomy
When adenoids become infected and swollen, they may block the nose and make it difficult to breathe. To compensate, patients with adenoiditis frequently breathe through their mouths. Because mouth-breathing may produce its own set of symptoms, including dry mouth, bad breath, cracked lips and nasal congestion, an adenoidectomy may be required. Other problems caused by infected and swollen adenoids that can be corrected by adenoidectomy include:
- Chronic ear infections
- Chronic sinus infections
- Difficulty swallowing
- Difficulty sleeping
- Nasal speech
- Swollen glands in the neck
An adenoidectomy may also help to alleviate persistent snoring and sleep apnea. After an adenoidectomy, most patients experience increased breathing through the nose, fewer sore throats, and fewer ear infections.
The Adenoidectomy Procedure
Because an adenoidectomy is performed through the mouth, no incision is necessary and the only cutting involves removal of infected tissue. Sometimes surgeons use techniques other than traditional surgery to remove the adenoids. The two primary methods used in such procedures are electrocautery, which uses electricity to heat and remove the glands, and radiofrequency energy (RFB), which uses unheated radiofrequency energy for the same purpose. Adenoidectomies are normally performed as outpatient procedures under general anesthesia.
Patients may experience sore throats or earaches, for up to two weeks after an adenoidectomy, and they may be treated with over-the-counter analgesics. There may also be swelling in the mouth, which causes residual mouth-breathing or snoring. White scabs in the mouth are normal after surgery and should not be picked because they will fall off naturally. It is important for a patient who has undergone an adenoidectomy to maintain hydration after surgery, and to be aware of complications signified by high or persistent fever, nausea and vomiting, headache, stiff neck or difficulty breathing.
Risks of an Adenoidectomy
While an adenoidectomy is a safe procedure, there are risks involved in any surgery. These risks may include:
- Excessive bleeding
- Blood clots
- Adverse reactions to anesthesia or medications
Post-surgical infection and breathing problems are also rare possible complications of an adenoidectomy.
