Summary
Necrotizing otitis externa management was standardized with a new protocol. This protocol addresses increasing cases and aims to improve patient outcomes in this serious ear infection.
Area of Science:
- Otolaryngology
- Infectious Diseases
Background:
- Necrotizing otitis externa (NOE) significantly impacts patient quality of life.
- NOE incidence is rising, with evolving patient demographics and management inconsistencies.
Purpose of the Study:
- To establish a practical and effective care protocol for standardizing NOE diagnosis and treatment.
Main Methods:
- Retrospective cohort study of 34 NOE patients (36 ears) from January 2015 to December 2020.
- Data analysis included patient demographics, pathogens, resistance patterns, imaging, treatment, and outcomes.
Main Results:
- The study identified Pseudomonas aeruginosa as the most common pathogen (50%), with 35% resistance to ciprofloxacin.
- Most patients (91%) required hospitalization; ceftazidime was the most prescribed antibiotic.
- Complications occurred in 35% of patients, including facial paralysis (12%) and mortality (9%).
Conclusions:
- A diagnostic and therapeutic protocol for necrotizing otitis externa was developed.
- This protocol serves as a dynamic tool for effective NOE management, requiring ongoing updates.

Introduction:For diagnosing acute pyelonephritis, a comprehensive patient history is collected to identify symptoms such as dysuria, frequent or urgent urination, flank pain, or costovertebral angle (CVA) tenderness that may suggest a kidney infection.Physical ExaminationDuring the physical examination, CVA tenderness is assessed. This involves gentle percussion over the costovertebral angle, where tenderness often indicates a kidney infection.Diagnostic TestsUrinalysis: Used to identify white...
