Acute and latent mastoiditis in children.

Area of Science:

• Otolaryngology
• Pediatric Otology
• Surgical Pathology

Background:

• Acute mastoiditis incidence has decreased significantly due to early antibiotic use.
• Secretory otitis media (SOM) remains a common condition requiring surgical intervention in some cases.
• Mastoidectomy is performed for persistent SOM with evidence of mastoid inflammation.

Purpose of the Study:

• To evaluate the incidence and outcomes of surgery for acute mastoiditis.
• To assess the prevalence and histological findings of mastoid inflammation in patients with SOM undergoing mastoidectomy.
• To determine the healing rates and factors influencing outcomes in SOM patients treated with mastoidectomy.

Main Methods:

• Retrospective analysis of surgical cases for acute mastoiditis and SOM between 1974-1981.
• Histopathological examination of mastoid tissue from SOM patients.
• Follow-up assessment of patients undergoing mastoidectomy for SOM.

Main Results:

• Low annual incidence (0.004%) of acute mastoiditis requiring surgery; all patients achieved full recovery.
• 52 ears with SOM underwent mastoidectomy, with 96% showing extensive mastoid inflammation.
• Post-mastoidectomy for SOM, 65% healed, while 35% retained tympanostomy tubes due to persistent Eustachian tube edema.

Conclusions:

• Early antibiotic treatment has drastically reduced the need for acute mastoiditis surgery.
• Secretory otitis media frequently involves significant mastoid inflammation, necessitating surgical intervention.
• Outcomes for SOM mastoidectomy are generally favorable, but Eustachian tube dysfunction can prolong recovery.
