Introduction
Suppurative parotitis is a localized suppurative infection that originates from the oral cavity and ascends to involve the parotid gland, commonly caused by *Staphylococcus aureus*, which may affect the orifice of the parotid duct. Typical symptoms include parotid swelling, high fever, chills, and general malaise. Purulent material often perforates the parotid fascia and infiltrates adjacent tissues, potentially compromising structures such as the pharynx.
In most cases, suppurative parotitis progresses to frank suppuration. The predominant symptom is swelling of the parotid gland, often accompanied by chills, generalized malaise, and high fever. It is classified into acute and chronic suppurative parotitis. Below, we address how suppurative parotitis is diagnosed.
How Is Suppurative Parotitis Diagnosed?
Suppurative parotitis is a localized purulent infection resulting from an ascending infection originating in the oral cavity, commonly caused by Staphylococcus aureus, which frequently involves the orifice of the parotid duct. Typical manifestations include parotid swelling, high fever, chills, and systemic malaise. Pus may penetrate the parotid fascia and infiltrate adjacent tissues, potentially compromising the pharynx and other nearby structures. Therefore, clinical evaluation may include ultrasonography, sialography, plain radiography, and complete blood count (CBC). Diagnosis is typically established based on clinical presentation combined with CBC findings.
Diagnosis relies on integration of patient history, clinical features, and diagnostic test results.
In chronic suppurative parotitis, physical examination of the parotid gland reveals mild erythema at the duct orifice. Gentle pressure on the gland may express turbid, “snowflake-like” saliva, viscous, egg-white–like saliva, or even mucinous plugs. The parotid gland may be only mildly swollen or appear normal. In long-standing cases, palpation reveals a firm, rubbery glandular texture, and the parotid duct feels thickened and cord-like.
Additional Information: Important Considerations in Parotitis Management
1. Brush teeth twice daily (morning and evening) and rinse the mouth after meals; periodontal cleaning may be required when indicated.
2. Patients with compromised immunity, prolonged bed rest, high fever, or fasting are prone to dehydration. Enhanced oral hygiene—including thorough toothbrushing and frequent rinsing with antiseptic solutions—is essential. Maintaining fluid balance, optimizing nutrition, and initiating appropriate antimicrobial therapy are also critical.
3. Maintain a nutritious diet consisting of liquid or semi-liquid foods. Increase intake of fresh vegetables and fruits. Avoid acidic and spicy or otherwise irritating foods, and ensure adequate hydration.
The above outlines the diagnostic approach to suppurative parotitis. We hope this information is helpful to you.
