From the Guidelines
The primary management for complications of odontogenic sinusitis involves prompt recognition, broad-spectrum antibiotics, and often surgical intervention to address both the sinusitis and the underlying dental infection. This approach is crucial because complications of odontogenic sinusitis can lead to severe morbidity, including permanent blindness, neurologic sequelae, or death if not treated promptly and appropriately 1. The management strategy should be tailored based on the severity of the complication, with mild cases potentially being managed on an outpatient basis with oral antibiotics like high-dose amoxicillin-clavulanate, but more severe cases requiring hospitalization for intravenous antimicrobial therapy and possible surgical intervention.
Key Considerations in Management
- Orbital Complications: These are among the most common complications and can range from preseptal cellulitis to more severe intraorbital infections. Management may include hospitalization and intravenous antibiotics, with vancomycin being considered to cover methicillin-resistant Streptococcus pneumoniae 1.
- Intracranial Complications: These are less common but can be life-threatening. They include conditions such as epidural or subdural abscess, brain abscess, venous thrombosis, and meningitis. Immediate neurosurgical consultation and intravenous antibiotics are essential in such cases.
- Surgical Intervention: This may be necessary for both drainage of the sinuses and definitive treatment of the dental source of infection. Functional endoscopic sinus surgery (FESS) can be used to drain the affected sinuses, and dental treatments may include extraction of the offending tooth, endodontic therapy, or repair of oroantral fistulas.
Antibiotic Therapy
The choice of antibiotic should be broad-spectrum, covering common pathogens involved in odontogenic infections, including aerobic and anaerobic bacteria. Amoxicillin-clavulanate is a commonly recommended initial antibiotic due to its broad coverage, including Streptococcus species, Haemophilus influenzae, and anaerobes 1. In cases of penicillin allergy, alternatives such as clindamycin plus a fluoroquinolone like levofloxacin can be considered. For severe infections requiring hospitalization, intravenous antibiotics such as ampicillin-sulbactam or ceftriaxone plus metronidazole may be used.
Importance of Addressing the Dental Source
Failure to address the underlying dental infection can lead to recurrence of sinusitis and potentially more severe complications. Therefore, definitive dental treatment is an essential component of the management plan for complications of odontogenic sinusitis. This may involve consultation with a dentist or oral surgeon to determine the appropriate dental intervention.

From the Research
Complications of Odontogenic Sinusitis
The primary management for complications of odontogenic sinusitis involves a combination of medical and dental treatments.
- Medical management includes antibiotics and saline nasal irrigation 2, 3
- Dental treatment focuses on addressing the underlying dental pathology, such as dental caries and periapical abscess 2, 4
- Endoscopic sinus surgery (ESS) may be necessary in cases where medical and dental management are unsuccessful, particularly in patients with smoking habits and severe CT findings of the sinus 2
Treatment Approaches
Different treatment approaches have been studied, including:
- Amoxicillin/clavulanic acid versus clindamycin for the treatment of odontogenic infections, with amoxicillin/clavulanic acid showing noninferiority to clindamycin 5
- Antimicrobial therapy in penicillin-allergic patients, with clindamycin being a common choice, but with a higher risk of treatment failure compared to amoxicillin-clavulanic acid 6
