Tonsillitis index: an objective tool for quantifying the indications for tonsillectomy for recurrent acute...

Area of Science:

• Otolaryngology
• Immunology
• Pediatric Medicine

Background:

• Recurrent acute tonsillitis (AT) poses a challenge for clinical decision-making regarding tonsillectomy.
• Objective metrics are needed to quantify the severity and chronicity of AT.
• Tonsil immunological function may be altered in cases of recurrent AT.

Purpose of the Study:

• To explore the utility of a novel Tonsillectomy Index (TI) for assessing indications for tonsillectomy in recurrent AT.
• To investigate the relationship between the natural history of AT, tonsillar immunological function, and the proposed TI.
• To evaluate if TI can predict tonsillar immunological deterioration.

Main Methods:

• A prospective study followed 11 children with AT for 5 years to track disease natural history.
• The Tonsillectomy Index (TI) was calculated as episodes of AT multiplied by years of occurrence.
• Immunological analysis of tonsillar B-lymphocytes (CD80, CD86 expression) was performed on 36 children and 46 adults undergoing tonsillectomy.

Main Results:

• Children with a TI ≥ 8 experienced a significantly higher number of AT episodes.
• Tonsillar B-lymphocytes in the AT group with TI ≥ 8 showed significantly decreased CD80 and CD86 expression compared to TI < 8 and control groups.
• Immunological markers suggest tonsillar tissue deterioration when TI reaches 8 or higher.

Conclusions:

• A TI score of 8 or greater may indicate significant immunological deterioration of tonsils in recurrent AT.
• Spontaneous resolution of recurrent AT is less likely when TI ≥ 8.
• The Tonsillectomy Index shows promise as an objective tool to aid surgical decision-making for tonsillectomy.
