**7. Conclusion**

A multitude of studies over the past 25 years have shown high success rates of primary repair around 90%, and secondary repair around 97%. These success rates compare favorably to traditional craniotomy approaches with reported success rates between 70 and 80% that carry a higher morbidity profile. Symptoms of failure in reconstruction include clear rhinorrhea and constant postnasal drip. Other signs may include meningitis, severe headaches, seizures, and worsening pneumocephalus.
