Introduction: The re-emergence of a vibrant neurosurgical unit in 2009 has allowed the performance of complex neurosurgical procedures including skullbase microsurgical and endoscopic approaches. These procedures are currently enhanced by experience gained through foreign partnerships and fellowships

Methods: We analyzed a prospective cohort of 135 adult patients who had microsurgery for skull base tumors in 2 neurosurgery units in southeast Nigeria from October 2009 to September 2015. Patients were followed up for 6 months to 5 years.

Results: 45 patients had anterior skullbase tumors, 67 had middle skull base tumors, while 23 had posterior skullbase lesions. M:F=1.45:1. mean age 51.3+/-2.9 years(95%CL). Male age(p=0.002 )and Posterior fossa location(p=0.003) were associated with higher risk of lesions with malignant phenotype. poor infrastructure support and Team learning curve limitations are significant identifiable odds

Conclusions: Microsurgery for skullbase lesions is on the ascendancy. Foreign Partnerships , mentorship and fellowships are main contributors to the current favourable trend

Patient Care: we have identified through mentoring and foreign parnerships, pearls in skullbase surgery which we are currently applying to microsurgical operative care of our patients

Learning Objectives: Foreign fellowships, mentorship and partnerships are significant posiive contributors to improved skullbase microsurgery in our experience
