Key points:
- There are many published series and reports regarding surgical
management of parapharyngeal space tumors mentioning neurological
complications.
- The reported incidence of neurological deficit is high in both benign
and malignant tumors.
- We have performed a comprehensive review of literature over the last
30 years (1989-2019).
- This systematic review and meta-analysis has revealed that tissue of
tumor origin (salivary vs neurogenic) is the key factor contributing
towards neurological complications.
- This preemptive assessment of anticipated range of neurologic
complications must be considered to educate the patients on the
post-operative sequelae and simultaneous preparation to facilitate
rehabilitation.
