Chronic Pharyngitis

16.7K
Chronic pharyngitis refers to persistent inflammation of the pharyngial mucosa.
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. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

Tonsillitis is inflammation of the tonsils, which are two lymphoid tissue masses at the back of the throat. This condition can cause discomfort and irritation in the throat.
Etiology
Three primary contributing factors have been identified.

Summary

Radiofrequency tonsillotomy is the primary method for treating pediatric upper airway obstruction in Sweden. This technique shows high symptom relief and low bleeding rates, with minimal differences between specific radiofrequency instruments used.

Area of Science:

  • Otolaryngology
  • Pediatric Surgery
  • Health Services Research

Background:

  • Tonsillotomy is increasingly used for pediatric upper airway obstruction.
  • Radiofrequency (RF) instruments are prevalent in tonsillotomy procedures.
  • Data on specific RF instrument outcomes in pediatric tonsillotomy are limited.

Purpose of the Study:

  • To categorize instruments used for tonsillotomy in Sweden.
  • To compare the outcomes and complication rates of different RF instruments for pediatric tonsillotomy.
  • To evaluate the effectiveness of RF tonsillotomy for upper airway obstruction.

Main Methods:

  • Retrospective analysis of data from the Swedish National Registry for Tonsil Surgery (2009-2012).
  • Inclusion of 1,676 children (aged 2-18) undergoing tonsillotomy for upper airway obstruction.
  • Categorization of instruments, focusing on radiofrequency devices (Coblation®, Surgitron®, CURIS®).

Main Results:

  • Radiofrequency instruments were used in 96% of cases.
  • Low postoperative bleeding rate (1.2%) and high symptom relief (95.1%) were observed.
  • No significant differences in bleeding, infection, or symptom relief between RF instruments; Coblation® associated with more days on analgesics.

Conclusions:

  • Radiofrequency tonsillotomy is the dominant technique for pediatric upper airway obstruction in Sweden.
  • The choice of RF instrument does not significantly impact key outcomes like bleeding or symptom relief.
  • While generally comparable, Coblation® may require a slightly longer period of analgesia post-procedure.
