Summary
This case report details a rare masticator space abscess in a 47-day-old infant, successfully treated with antibiotics after ultrasound-guided drainage. The infant recovered fully, highlighting a non-odontogenic cause in neonates.
Area of Science:
- Pediatric infectious diseases
- Head and neck surgery
- Medical imaging
Background:
- Masticator space abscesses are uncommon in infants.
- Typically, these abscesses stem from odontogenic infections in adults.
- Neonatal infections can present atypically.
Purpose of the Study:
- To report a rare case of masticator space abscess in a neonate.
- To highlight the diagnostic and therapeutic approach in this age group.
- To discuss potential non-odontogenic causes in infants.
Main Methods:
- Clinical presentation of fever, irritability, and buccal swelling in a 47-day-old infant.
- Contrast-enhanced computed tomography (CT) scan of the neck identifying a masticator space abscess.
- Ultrasound-guided extraoral aspiration of the abscess for diagnosis and treatment.
Main Results:
- Staphylococcus aureus identified in pus and blood cultures.
- Successful treatment with antibiotics following aspiration.
- Complete resolution of the abscess confirmed by follow-up ultrasonography.
Conclusions:
- Masticator space abscess can occur in neonates without odontogenic infection.
- Septicemia is a potential underlying cause in infants.
- Prompt diagnosis and intervention are crucial for favorable outcomes.

Brain Abscess l: Introduction
A brain abscess is a focal, intracerebral infection characterized by a localized collection of pus within the brain parenchyma, resulting from microbial invasion and the body’s inflammatory response. It progresses through stages: early and late cerebritis, followed by early and late capsule formation, reflecting tissue destruction, immune response, and eventual encapsulation.Etiology and PathogenesisCausative organisms vary with source and host factors, often involving polymicrobial infections,...
Development of the Oral Microbiota
The establishment of the oral microbiome begins before birth, challenging the long-held belief that the fetal oral cavity is sterile. The presence of oral microbes such as Streptococcus and Fusobacterium in amniotic fluid suggests that microbial exposure may occur in utero, potentially through translocation from the maternal oral or gastrointestinal tract. This early colonization primes the neonatal immune system and sets the stage for subsequent microbial succession. Maternal health,...
