Insights
Bacteremia is more common after adenotonsillectomy than adenoidectomy, especially in children with recurrent acute otitis media or recurrent tonsillopharyngitis. Nasopharyngeal bacteria often correlate with bloodstream infections during these procedures.
Area of Science:
- Otolaryngology
- Pediatric Surgery
- Infectious Disease
Background:
- Adenoidectomy and adenotonsillectomy are common pediatric procedures.
- Bacteremia, the presence of bacteria in the bloodstream, can occur during these surgeries.
- Understanding the incidence and risk factors for bacteremia is crucial for patient safety.
Purpose of the Study:
- To determine the incidence and persistence of bacteremia in children undergoing adenoidectomy or adenotonsillectomy.
- To investigate the association between the type of surgery and bacteremia.
- To explore the link between pre-existing conditions and bacteremia.
Main Methods:
- 130 children were enrolled, undergoing adenoidectomy (for recurrent acute otitis media or persistent otitis media with effusion) or adenotonsillectomy (for obstructive sleep apnea syndrome or recurrent tonsillopharyngitis).
- Bacterial cultures were performed on nasopharyngeal aspirates, surgical tissue, and blood samples taken pre- and post-operatively.
- Statistical analysis was used to compare bacteremia rates across different surgical groups and indications.
Main Results:
- Adenotonsillectomy was associated with a significantly higher incidence of positive blood cultures compared to adenoidectomy.
- Children with recurrent acute otitis media or recurrent tonsillopharyngitis had higher rates of bacteremia than those with persistent otitis media with effusion or obstructive sleep apnea syndrome.
- Nasopharyngeal colonization significantly increased the likelihood of positive blood cultures, with matching bacteria found in 80% of cases.
Conclusions:
- Bacteremia is significantly more frequent following adenotonsillectomy than adenoidectomy.
- Patients with a history of recurrent acute otitis media or recurrent tonsillopharyngitis are at higher risk for bacteremia during these procedures.
- Nasopharyngeal and tonsillar/adenoidal bacterial presence is a strong indicator for bacteremia during surgery.
Objective:
To evaluate the incidence and persistence of bacteremia in children undergoing adenoidectomy or adenotonsillectomy for different medical reasons.
Methods:
We enrolled 130 children scheduled for adenoidectomy because of recurrent acute otitis media (rAOM, 15) or persistent otitis media with effusion (pOME, 33), or for adenotonsillectomy because of obstructive sleep apnea syndrome (OSAS, 41) or recurrent tonsillopharyngitis (rTF, 41). Nasopharyngeal aspirates taken just before surgery, swabs of the ablated central adenoidal and tonsillar tissues, and blood samples taken within the first 30s of beginning the operation and 20min after its end were used for bacterial cultures.
Results:
The incidence of positive blood cultures after the beginning of the operation was significantly higher in the children who underwent adenotonsillectomy than in those who underwent adenoidectomy, and in those with rAOM or rTF than in those with pOME or OSAS. Children with nasopharyngeal colonisation were significantly more likely to have a positive blood culture than those without. Twenty of the 25 children with a positive blood culture (80.0%), had the same bacteria in their nasopharyngeal and adenoidal/tonsillar tissues.
Conclusions:
Our results show that bacteremia is significantly more frequently associated with adenotonsillectomy than with adenoidectomy, and significantly more frequent in patients with a history of rAOM or rTF.

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.
