Summary
External auditory canal cholesteatoma (EACC) is often diagnosed late. Recognizing risk factors like nicotine use and symptoms such as ear pain can speed up detection and treatment, leading to good outcomes.
Area of Science:
- Otolaryngology
- Dermatology
- Medical Research
Background:
- External auditory canal cholesteatoma (EACC) presents diagnostic and management challenges.
- Delayed diagnosis of EACC can lead to increased morbidity.
Purpose of the Study:
- To review the current understanding of EACC, including its symptoms, clinical presentation, and treatment.
- To identify strategies to reduce diagnostic delays for EACC.
Main Methods:
- A comprehensive literature search was conducted across PubMed, CINAHL, Cochrane Library, and SCOPUS.
- Meta-analyses were performed on data from 30 studies involving 1007 patients diagnosed with EACC.
Main Results:
- The majority of patients (60.7%) were diagnosed with Stage III EACC.
- Common risk factors included nicotine use (33.1%) and cotton swab abuse (24.3%).
- Otalgia (39.9%) and otorrhea (50.3%) were frequent symptoms, but 15.7% were asymptomatic. Treatment involved conservative measures and surgical interventions like canalplasty (68.6%), with low recurrence rates (4.5%).
Conclusions:
- EACC is frequently diagnosed at advanced stages, underscoring the need for early recognition.
- Identifying key risk factors and symptoms is crucial for timely diagnosis and effective management.
- Tailored interventions can achieve low recurrence rates and mitigate the impact of delayed diagnosis.

Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

Individuals with Barrett's esophagus are often asymptomatic, but they may experience symptoms commonly associated with GERD, such as heartburn and acid regurgitation. Additional symptoms can include difficulty swallowing, chest pain, unintentional weight loss, blood in the stool (which may appear black, tarry, or bloody), and episodes of vomiting.
To diagnose Barrett's esophagus, healthcare providers often recommend an endoscopy for those showing symptoms of acid reflux. The procedure...
