title: Pott's puffy tumor and epidural abscess arising from dental sepsis: a case report.
abstract: OBJECTIVE
  To present an unusual case of two uncommon cranial complications of frontal sinusitis: Pott's puffy tumor and epidural abscess arising from frontal sinusitis of dental origin, and also two systemic complications of sinusitis: septicemia and empyema, all occurring in an immunocompetent patient.
  
  
  METHODS
  A 21-year-old man presented with a scalp swelling and epidural abscess. Magnetic resonance imaging and computed tomographic scans revealed unilateral opacification of the frontal sinus and an epidural abscess with a direct connection to the scalp abscess. Further history revealed that his symptoms occurred coincidentally with a tooth extraction 2 months before, and he was hospitalized soon after the tooth extraction for sepsis and a lung abscess.
  
  
  METHODS
  A combined neurosurgical and otolaryngologic approach was required to treat the sinusitis and the associated epidural and scalp abscess.
  
  
  RESULTS
  Cultures returned as Streptococcus intermedius from all three sites. The patient was free of disease at the 3-month follow-up.
  
  
  CONCLUSIONS
  Odontogenic maxillary sinusitis is well documented; however, there is little reported of frontal sinusitis arising from dental disease. The prevalence of sinusitis of dental origin will be reviewed, including the microbiology of this particularly virulent organism that persisted despite earlier treatment with ampicillin. Also, the current thoughts on management of these cases will be discussed with particular reference to local therapy for sinusitis in addition to systemic treatment with antibiotics.
