[Acute mastoiditis: experience in a tertiary-care center in the South of Spain during 1999-2008 period]

Retrospective study of acute mastoiditis in children in Spain attended in a Pediatric Emergency department

OBJECTIVE

To analyze the cases of acute mastoiditis, characteristics, management and complications in children attended in the emergency department.

METHODS

Retrospective study of acute mastoiditis in a Spanish tertiary hospital over a 6-year period (2018-2023).

RESULTS

One hundred two episodes of acute mastoiditis were analyzed (54% males, median age 1.8 years). Microorganisms were isolated in one third of cases, mainly Streptococcus pyogenes (64% of ear secretion cultures). Complications occurred in 27.5%, primarily subperiosteal abscess. A younger age, absence of vaccination schedule, previous history of otitis, cochlear implant carriers or white blood cell counts and C-reactive protein levels were not associated with complications. Complicated cases had longer hospitalizations. Treatment included antibiotics, corticosteroids, and surgery in 50% of cases.

CONCLUSIONS

This study shows an increase of acute mastoiditis during 2023, with a relevant role of S. pyogenes. A younger age, absence of vaccination, personal history of otitis or cochlear implant, blood cell counts and C-reactive protein levels were not associated with complications.

Acute mastoiditis in children: contemporary opportunities and challenges

BACKGROUND

Mastoiditis is the most common intra-temporal complication of acute otitis media. Despite potentially lethal sequelae, optimal management remains poorly defined.

METHOD

A retrospective case review was conducted of children diagnosed with mastoiditis at a tertiary referral centre, in North East England, between 2010 and 2017.

RESULTS

Fifty-one cases were identified, 49 without cholesteatoma. Median patient age was 42 months (2 months to 18 years) and median hospital stay was 4 days (range, 0-27 days). There was no incidence trend over time. Imaging was conducted in 15 out of 49 cases. Surgery was performed in 29 out of 49 cases, most commonly mastoidectomy with (9 out of 29) or without (9 out of 29) grommets. Complications included sigmoid sinus thrombosis (3 out of 49) and extradural abscess (2 out of 51), amongst others; no fatalities occurred.

CONCLUSION

A detailed contemporary description of paediatric mastoiditis presentation and management is presented. The findings broadly mirror those published by other UK centres, but suggest a higher rate of identified disease complications and surgical interventions.

Panel 8

Background and Objectives

Although serious complications of otitis media (OM) such as brain abscess are rare, sequelae of OM such as tympanic membrane perforation and atelectatic tympanic membrane are quite common. Inner ear sequelae can cause hearing loss and speech and language problems. The objectives of this article are to provide a state-of-the-art review on recent articles on complications and sequelae of OM in different anatomic locations, from the tympanic membrane to intracranial sites, as well as hearing loss and speech and language development.

Data Sources

Primarily PubMed supplemented by Ovid MEDLINE and the Cochrane Database.

Review Methods

All types of articles related to OM complications and sequelae published in English between January 2007 and June 2011 were identified. A total of 127 relevant quality articles are summarized and included in this report.

Results

Key findings are summarized based on the following major anatomic locations and categories: tympanic membrane; cholesteatoma; ossicular problems; mucosal sequelae; inner ear sequelae; speech and language development; extracranial areas, including mastoiditis and facial nerve paralysis; intracranial complications; and future research goals. New information and insights were gained to prevent complications and sequelae.

Conclusion and Implications for Practice

Over the past 4 years, progress has been made in advancing the knowledge on the complications and sequelae of OM, which can be used to prevent and treat them effectively. Areas of potential future research have been identified and outlined.

[Acute mastoiditis in the pneumococcal vaccine era]

INTRODUCTION AND OBJECTIVES

Acute mastoiditis is the most common complication of acute otitis media. Recent studies have noticed an increase in cases. The goal of this study was to review acute mastoiditis cases diagnosed in children younger than 14 years old.

MATERIAL AND METHODS

A retrospective study of all patients under 14 years old admitted with a diagnosis of mastoiditis between 1996 and 2008 was performed. Epidemiological, laboratory and clinical variables were analysed.

RESULTS

Sixty-one charts were reviewed. The mean age was 28 months; 55.7% of the patients were male. Most cases were in the autumn and winter; 79% occurred from 2002 to 2008. Most cases (82%) had antecedents of an upper airway catarrhal process and 60.7% had a clinical diagnosis of acute otitis media. Prior antibacterial agent therapy had been administered in 55.7% of the cases. Culture of middle ear effusions was performed in 48 patients, revealing Streptococcus pneumonia in 39.7%, Haemophilus influenzae in 2%, Staphylococcus aureus in 12.5% and Pseudomonas aeruginosa in 8.3%. Cultures were sterile in 18 patients (37.5%). Of the pneumococcal isolates, 26.2% were resistant to penicillin or third generation cephalosporins. Most cases (93.4%) responded well to antibacterial therapy alone or with myringotomy. There were complications in 7 patients (11.5%). Mastoid surgery was performed in 4 patients.

CONCLUSIONS

Acute mastoiditis shows a rising incidence in recent years. The most commonly isolated form is the pneumococcus, the high rates of antibiotic resistance in our study being notable. Treatments with antibiotics alone or in combination with myringotomy are effective in less severe forms.
