Caseous Tonsillitis or Tonsil Stones

Caseous tonsillitis occurs when food remnants, dead mucosal cells, saliva, and bacteria accumulate in the tonsillar crypts, which are small cavities naturally present on the surface of the tonsils. These formations, white or yellowish in color, can vary in size and quantity and are composed of decomposing organic material.

The term “caseum” derives from the Latin word meaning “cheese,” due to the consistency and appearance of these formations. The palatine tonsils have crypts whose function is to capture microorganisms to prevent infections; however, when these cavities enlarge, they facilitate the accumulation of debris.

Main Symptoms

Patients with caseous tonsillitis frequently present:

• Persistent halitosis caused by the production of volatile sulfur compounds by anaerobic bacteria present in the tonsil stones
• Sensation of a foreign body in the throat, constant discomfort as if something were “stuck” in the area
• Expulsion of small white or yellowish balls that may be expelled during speaking, coughing, or sneezing, always accompanied by an unpleasant odor
• Sore throat or discomfort when swallowing, especially when the tonsil stones are larger
• Swollen tonsils due to the accumulation of material
• Altered taste, with an unpleasant taste in the mouth

Symptoms usually subside after the spontaneous expulsion of the tonsil stones but may return frequently in predisposed patients.

Causes and Risk Factors

The formation of tonsil stones is related to several factors:

• Tonsil anatomy: people with large tonsils or with many deep crypts have a greater predisposition
• Inadequate oral hygiene: poor brushing facilitates the accumulation of bacteria and food remnants
• Changes in oral pH: these may occur due to gastroesophageal reflux, respiratory diseases, or problems with the salivary glands
• Decreased salivary flow: medications that cause dry mouth, such as antihypertensives and antidepressants, favor the formation of tonsil stones
• Recurrent respiratory infections: rhinitis, sinusitis, and allergies increase mucus production that can accumulate in the tonsils
• Inadequate habits: smoking, alcohol consumption, and long intervals between meals can contribute to the problem
• History of tonsillitis: people who have had frequent infections present a greater risk of developing the condition

Diagnosis

The diagnosis of caseous tonsillitis is essentially clinical, based on the assessment of symptoms and the physical examination performed by the otolaryngologist (ENT). During the consultation, an oroscopy is performed to directly visualize the tonsils and identify the tonsil stones. Gentle pressure on the tonsils during the examination may cause the tonsil stones to be expelled, confirming the diagnosis. Complementary tests are generally not necessary, as the diagnosis can be established by direct observation of the characteristic formations. It is important to differentiate it from acute infectious tonsillitis, which presents active inflammation and systemic symptoms such as fever.

Treatment Options

Conservative Treatment

The initial management of caseous tonsillitis involves conservative measures that can provide relief of symptoms:

• Strict oral hygiene: proper tooth brushing, use of dental floss, and antiseptic mouthwashes to reduce the bacterial load
• Gargling with saline solution: performed with warm water and salt, this can help remove tonsil stones and reduce local inflammation
• Adequate hydration: frequent intake of fluids to keep the tonsillar crypts clean
• Use of specific mouthwashes: studies demonstrate the efficacy of specialized mouthwashes in reducing the formation of tonsil stones and improving halitosis
• Dietary changes: avoiding foods that favor the accumulation of residue in the tonsils

It is essential to advise the patient not to try to remove the tonsil stones manually, as this can cause injuries and secondary infections.

Surgical Treatment

When conservative measures do not provide adequate relief and the symptoms significantly impact quality of life, surgical treatment may be considered.

Extracapsular Removal with Radiofrequency

Extracapsular removal with radiofrequency is a minimally invasive technique that aims to remove the tonsils while preserving the capsule, which results in a surgery with much less pain and less tissue damage.

The advantages of this technique include less bleeding during and after the procedure, the possibility of returning to a normal diet more quickly, and a faster recovery compared to traditional tonsillectomy.

Tonsillectomy

Complete removal of the tonsils represents the definitive solution for caseous tonsillitis, being indicated in cases of persistent and significant discomfort, failure of conservative treatment, or severe impact on social and professional quality of life. Tonsillectomy can be performed using different techniques. The procedure definitively eliminates the problem, as it completely removes the crypts where the tonsil stones form.

When to Seek Specialized Treatment

It is recommended to consult an otolaryngologist (ENT) when:

• Bad breath persists even with good oral hygiene
• There is intense sore throat or difficulty swallowing
• Recurrent infections occur in the area
• The symptoms cause social or professional embarrassment
• Conservative measures do not provide adequate improvement

Prevention

Although it is not always possible to completely prevent the formation of tonsil stones, some measures can reduce their occurrence:

• Maintain excellent oral hygiene with regular brushing and use of dental floss
• Gargle with warm water and salt regularly
• Stay well hydrated throughout the day
• Avoid smoking and excessive alcohol consumption
• Adequately treat respiratory problems such as rhinitis and sinusitis
• Have regular dental follow-up

Caseous tonsillitis, although benign, can significantly impact quality of life due to the uncomfortable symptoms it causes. Early diagnosis and appropriate treatment, whether conservative or surgical, can provide effective relief of symptoms and improve the patient’s social confidence.
