Summary
Ultrasonography shows 82% sensitivity for diagnosing peritonsillar abscess (quinsy) in uncertain cases. This imaging technique aids in confirming the presence of pus before surgery, minimizing unnecessary procedures.
Area of Science:
- Otolaryngology
- Diagnostic Imaging
Background:
- Peritonsillar abscess, also known as quinsy, is a common complication of tonsillitis.
- Accurate diagnosis is crucial for timely surgical intervention and preventing complications.
Purpose of the Study:
- To evaluate the diagnostic sensitivity of B-mode ultrasonography for peritonsillar abscess (quinsy).
Main Methods:
- A prospective study conducted from 1986 to 1989.
- B-mode ultrasonography of the tonsils was performed on 36 patients with clinically uncertain peritonsillitis before tonsillectomy.
- Sensitivity and false positive rates were calculated.
Main Results:
- Ultrasonography demonstrated a sensitivity of 82% in diagnosing peritonsillar abscess in cases with clinical uncertainty.
- Only four false positive results were recorded, where an abscess was indicated on the scan but not found during surgery.
Conclusions:
- Ultrasonography is a valuable tool for improving the diagnostic accuracy of peritonsillar abscess (quinsy).
- The method shows high sensitivity and a low false positive rate, aiding in surgical decision-making.
