Acute otalgia in children - findings and diagnosis
Insights
Diagnosing acute otitis media (AOM) in children requires a physical examination. Symptoms like ear pain alone are often unreliable, as they can indicate referred pain or other conditions, necessitating an otoscopic evaluation.
Area of Science:
- Pediatrics
- Otolaryngology
- Infectious Diseases
Background:
- Acute otitis media (AOM) is a common childhood illness causing ear pain (otalgia).
- Clinical diagnosis of AOM often relies on symptom assessment, but symptom overlap can complicate diagnosis.
Purpose of the Study:
- To determine if symptoms reliably predict acute otitis media in children.
- To assess the necessity of otoscopic examination for diagnosing AOM in pediatric patients presenting with otalgia.
Main Methods:
- A prospective study involving 171 children aged 15 years or younger presenting with acute otalgia.
- Clinical evaluation including symptom assessment and otoscopic examination to diagnose AOM, simplex otitis, serous otitis media, or normal eardrums.
Main Results:
- Acute otitis media (AOM) was diagnosed in 46% of children; 54% had other conditions or normal eardrums.
- Fever (78%) and eardrum perforation (30%) were common in AOM cases.
- Non-AOM otalgia was often referred pain from throat discomfort, nasal obstruction, or teething.
Conclusions:
- Otalgia and other symptoms like fever or upper respiratory tract infection (URI) can occur without AOM.
- Accurate otoscopic examination is crucial for diagnosing AOM in children with otalgia or URI symptoms.
- Physicians lacking otoscopic capabilities should promptly refer patients to an otologist.
Abstract:
One hundred and seventy-one children up to 15 years of age and with acute otalgia were examined to find out whether otalgia or any other symptoms were so closely related to acute otitis media (AOM) as to make otoscopic examination unnecessary. AOM was diagnosed in 46%, simplex otitis in 15%, serous otitis media (SOM) in 17%, and normal eardrums in 22%. Children with AOM had fever and spontaneous perforation of the eardrums in 78% and 30% of the cases, respectively. Of the children who had not AOM (54%), the otalgia could in most cases be classified as referred pain due to, for instance, discomfort when swallowing, nasal obstruction or throat pain. Other reasons were general irritability due to fever, teething or moderate hearing loss. The difficulties in diagnosing AOM simply on the basis of symptoms were demonstrated in the investigation. Symptoms such as otalgia, otorrhea, fever or upper respiratory tract infection (URI), possibly except for the combination of otorrhea and fever, can occur without AOM. A correct otoscopic examination and evaluation of the eardrums is necessary in children with otalgia, other symptoms of URI or in doubtful cases of acute illness. Physicians without possibilities to evaluate the eardrums properly should thus refer the patient to an otologist without delay.
