Insights
Suppurative thyroiditis in children is rare and often linked to a piriform sinus tract. Early diagnosis via hypopharyngoscopy and treatment with cauterization or excision offers a cure.
Area of Science:
- Pediatric Endocrinology
- Otolaryngology
- Infectious Diseases
Background:
- Suppurative thyroiditis is an uncommon pediatric infection.
- Left-sided intrathyroidal abscesses in children warrant suspicion for a piriform sinus tract.
Purpose of the Study:
- To determine the causes of suppurative thyroiditis in pediatric patients.
- To propose a management strategy for this condition.
Main Methods:
- A case series involving 5 pediatric patients diagnosed with suppurative thyroiditis between 1999 and 2007.
- Diagnostic tools included barium swallows and telescopic hypopharyngoscopy.
- Treatment involved incision and drainage, tract excision, or silver nitrate cauterization.
Main Results:
- All patients presented with left-sided intrathyroidal abscesses.
- Piriform sinus tracts were identified in 2 patients via barium swallow and in all 5 via hypopharyngoscopy.
- Treatments included abscess drainage, tract excision, or cauterization, leading to asymptomatic outcomes for all patients.
Conclusions:
- Suppurative thyroiditis in children is rare and frequently associated with piriform sinus tracts.
- Hypopharyngoscopy is crucial for diagnosing the internal opening of the tract.
- Endoscopic cauterization of the internal opening is a safe, effective, and potentially curative treatment with minimal morbidity.
Objective:
To elucidate the etiology of suppurative thyroiditis in children and recommend a management algorithm.
Methods:
Case series of 5 pediatric patients with a diagnosis of suppurative thyroiditis seen between January 1999 and April 2007.
Results:
All 5 patients primarily presented with left-sided intrathyroidal abscesses. The number of infections from first presentation to the time of definitive diagnosis ranged from 1 to 5. Three patients underwent incision and drainage of the abscess once, and 2 had the procedure performed 3 times. Barium swallows identified a piriform sinus tract on the left side in 2 of the 5 patients. Telescopic hypopharyngoscopy identified the internal opening in all 5. Three were managed with complete excision of their tracts and 2 with cauterization of the internal opening with silver nitrate. All 5 are currently asymptomatic.
Conclusions:
Suppurative thyroiditis is a very rare infection in children. A left-sided intrathyroidal abscess should immediately arouse suspicion of a piriform sinus tract. Barium swallows may identify the etiology in some cases. Definitive diagnosis requires a hypopharyngoscopy, with detailed telescopic examination of the left piriform fossa apex. Endoscopic chemical cautery of the internal opening is a safe and effective technique, with very low morbidity, and has the potential for cure.

Tonsillitis II: Management
Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:
Myocarditis III: Medical Management
Acute Pyelonephritis II: Diagnostic Studies and Management
Graves Disease II: Pathophysiology
Chronic Pharyngitis
Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants.
