Introduction

Purulent discharge from the ear canal may be caused by external otitis, furuncle of the ear canal, suppurative otitis media, acute upper respiratory tract infection, eczema, or other conditions. Inflammation of the ear canal can damage the local skin barrier due to irritation, allowing bacterial invasion and resulting in purulent discharge, sometimes accompanied by ear pain. Treatment may include medications such as ciprofloxacin hydrochloride tablets or levofloxacin capsules, as directed by a physician.

Purulent discharge from the external auditory canal may be caused by conditions such as external otitis, furuncle of the external auditory canal, suppurative otitis media, acute upper respiratory tract infection, or eczema.

1. External Otitis

Inflammation affecting the external auditory canal can damage the local skin barrier, allowing bacterial invasion and resulting in purulent discharge, possibly accompanied by ear pain. Treatment may include medications such as ciprofloxacin hydrochloride tablets, levofloxacin capsules, or cefalexin capsules, used according to medical advice.

2. Furuncle of the External Auditory Canal

Infection with Staphylococcus aureus in the external auditory canal leads to the formation of abundant pus that drains from the skin surface, causing the aforementioned symptoms, sometimes accompanied by headache. Treatment under medical guidance may include ichthammol ointment or levofloxacin hydrochloride ear drops.

3. Suppurative Otitis Media

Bacterial infection causes accumulation of pus in the middle ear, triggering an inflammatory response and increasing pressure within the middle ear cavity. This may damage or perforate the eardrum, allowing pus to flow into the external auditory canal, leading to the symptoms described, possibly accompanied by hearing loss. Treatment may involve chloramphenicol ear drops, boric acid and borneol ear drops, or levofloxacin hydrochloride ear drops, as directed by a physician.

4. Acute Upper Respiratory Tract Infection

During illness, immune cells release inflammatory mediators while fighting bacteria or viruses. Infection and inflammation may spread from the respiratory tract or skin to the external auditory canal, causing the above condition, possibly accompanied by fever. Under medical supervision, hydrogen peroxide may be used to clean the pus and maintain ear hygiene, while anti-inflammatory and anti-infective treatment may include cefixime granules, cefalexin capsules, or amoxicillin-clavulanate potassium dispersible tablets.

5. Eczema

Eczema affecting the skin around the ear can cause itching or skin damage, leading to bacterial infection, inflammation of the external auditory canal, and purulent secretion—resulting in the aforementioned symptoms, often accompanied by localized itching. Under medical guidance, treatment may include loratadine tablets, chlorpheniramine maleate tablets, or mometasone furoate cream.

Patients are advised to seek timely medical evaluation for accurate diagnosis and appropriate treatment under professional supervision to promote recovery.
