Abstract
Objectives
Based on current evidence, this systematic review focuses on various gray areas related to these patients' diagnosis, management, and follow-up in central skull base osteomyelitis (CSBO).
Study Design
A systematic review of all case reports and observational studies.
Methods
We systematically searched PubMed, Scopus database, Cochrane database, U.K. clinicaltrails.gov registry, and World Health Organization International Clinical Trials Registry Platform and included all reports as per our inclusion criteria. Data was analyzed systematically, and we made essential observations.
Results
Out of 179 articles, 25 were selected according to inclusion criteria and quality assessment. Among the 44 patients, refractory headache (95%) was the most common presentation, followed by cranial nerve paralysis (82%) and Pseudomonas (32%) as the most common bacteria. Contrary to the available literature the disease cure was worse in those who underwent targeted biopsy (64% vs. 36%, p = 0.023) and surgical debridement (61% vs. 39%, p = 0.013) in the late stages of the disease.
Conclusion
Otogenic osteomyelitis can spread to central skull bones in the absence of obvious ear symptoms. Early diagnosis and intervention of CSBO before progression to late stages can help decrease significant morbidity and mortality.
