Summary

Masticator space abscesses, often from mandibular molar infections, can mimic tumors. Surgical drainage and molar extraction led to a cure in this complex case.

Area of Science:

  • Otorhinolaryngology
  • Oral and Maxillofacial Surgery
  • Infectious Diseases

Background:

  • The masticator space is complex, making diagnosis and treatment of neoplasms and infections challenging.
  • Abscesses in this region can present with non-specific symptoms, complicating early identification.

Observation:

  • A 66-year-old man presented with a chronic nasopharyngeal masticator space abscess mimicking a neoplastic lesion.
  • Initial presentation included subtle signs of infection over five years, with physical and CT findings suggestive of a tumor.

Findings:

  • The abscess originated from periodontal infection and osteomyelitis of the mandibular molars.
  • Infection spread along mastication muscles, forming abscesses in the masseter and temporalis muscles.
  • Surgical intervention via the maxillary sinus facilitated diagnosis, pus drainage, and subsequent cure.

Implications:

  • Masticator space abscesses frequently stem from mandibular molar infections, requiring thorough dental evaluation.
  • Imaging modalities like CT, MRI, and bone scans are crucial for assessing infection spread in mastication muscles and mandibular bone.
  • Understanding infection pathways is key for accurate diagnosis and effective treatment of masticator space abscesses.
