What is the treatment for a patient who has stabbed themselves in the mouth near the tonsil with a toothbrush?

Management of Oral Injury from Toothbrush Impalement Near the Tonsil

Immediate evaluation and management of the wound is essential, including assessment for vascular injury, infection risk, and potential airway compromise.

Initial Assessment and Management

• Inspect the wound thoroughly to determine the extent of injury, depth of penetration, and proximity to vital structures 1
• Clean the wound with saline solution or clean water to remove debris and reduce infection risk 1
• Control any bleeding by applying gentle pressure with sterile gauze 1
• Assess for signs of potential vascular injury (excessive bleeding, expanding hematoma) or airway compromise (difficulty breathing, stridor) which would require immediate emergency intervention 2, 3

Wound Care

• Gently rinse the mouth with warm saline mouthwash to cleanse the area 1
• For pain management, use an anti-inflammatory oral rinse containing benzydamine hydrochloride every 3 hours, particularly before eating 1
• Apply white soft paraffin ointment to any affected mucosal surfaces to provide protection and comfort 1
• Use an antiseptic oral rinse containing chlorhexidine twice daily to prevent infection 1

Antibiotic Considerations

• Consider prophylactic antibiotics if the wound is deep, contaminated, or near vital structures to prevent infection 2, 3
• Broad-spectrum antibiotics covering oral flora are recommended for penetrating injuries of the oral cavity 2, 3

Follow-up Care

• Daily oral review is necessary during the acute healing phase 1
• Instruct the patient to maintain good oral hygiene but avoid vigorous brushing near the injury site 1
• Recommend a soft diet and avoidance of spicy, hot, or acidic foods that may irritate the wound 1
• Monitor for signs of infection (increasing pain, swelling, fever, purulent discharge) which would require prompt medical attention 1

Special Considerations

• For deep penetrating injuries or those with significant tissue damage, imaging (CT scan) may be necessary to rule out injury to deeper structures 2, 3
• If the wound is extensive or involves the tonsil significantly, ENT consultation should be considered 1, 3
• In cases where the toothbrush has completely impaled tissues or cannot be removed, emergency surgical intervention is required 2, 3

Prevention of Future Injuries

• Educate the patient about proper toothbrush handling and oral hygiene techniques 1
• For patients with developmental disorders or those at risk for self-injury, consider supervised brushing or specialized toothbrushes 4, 3

Common Pitfalls to Avoid

• Do not underestimate seemingly minor oral injuries, as they can lead to serious complications if they involve deeper structures or become infected 2, 3
• Never attempt forceful removal of any embedded foreign body without proper visualization and control 2
• Do not delay treatment of oral injuries as the rich vascularity of the oral cavity can lead to rapid spread of infection 1
