# Nasopharyngeal and temporal bone abscess following necrotizing otitis externa: a case report

## TL;DR

A 70-year-old man with uncontrolled diabetes developed severe ear infection complications, including abscesses in the temporal bone and nasopharynx, caused by a rare bacteria.

## Contribution

Reports a rare case of NOE leading to temporal bone and nasopharyngeal abscesses caused by Klebsiella pneumoniae.

## Key findings

- NOE can lead to severe complications like temporal bone and nasopharyngeal abscesses.
- Klebsiella pneumoniae is a rare but serious pathogen in NOE cases.
- Multidisciplinary treatment with antibiotics and imaging is essential for managing such complications.

## Abstract

Necrotizing otitis externa (NOE) is a severe infection primarily affecting the external auditory canal, seen mainly in immunocompromised individuals as patients with diabetes mellitus (DM). This case report highlights unusual complications of NOE: temporal bone and nasopharyngeal abscesses. These complications underscore the severity of NOE, particularly when caused by rare pathogens such as Klebsiella species. We detail the case of a 70-year-old male with uncontrolled DM who presented with severe right ear pain, purulent discharge, and significant postauricular swelling. Laboratory investigations revealed elevated inflammatory markers and poorly controlled diabetes. Cultures confirmed Klebsiella pneumoniae, and imaging showed diffuse edema and abscess formation in the temporal bone and nasopharynx. The patient was treated with intravenous Ceftazidime and ciprofloxacin for 6 weeks, followed by oral ciprofloxacin. Effective management of NOE necessitates a comprehensive, multidisciplinary approach. Early intervention, regular monitoring, and imaging are critical for promptly detecting and managing complications.
