To study the clinical presentation, intraoperative findings and surgical management in Meningo-encephalic-herniation (MEH) based on the etiology. The inclusion criteria were intraoperatively verified MEH in patients with a minimum follow-up of 12 months which yielded 262 operated ears. The data were extracted regarding demographics, laterality, clinical presentation, past surgeries, contralateral-ear condition, intraoperative findings, complications, recurrences, revision-surgeries, audiometric-data and follow-up. The mean age at surgery was 49.7 years with the involvement of right-ear in 53.8% of cases. Lesions were categorized based on the etiology as chronic-otitis-media with/without cholesteatoma-MEH (COM/CHOL-MEH)-47.7%; iatrogenic-MEHs -20.9%; traumatic-MEHs -8% and spontaneous-MEHs-23.3%. At presentation, hearing loss (100% and 98.2%) and otorrhea (65.6% and 49.1%) were predominant in COM/CHOL-MEHs and iatrogenic-MEHs respectively. On the other hand, meningitis (23.9% and 14.3%) and cerebrospinal fluid-leak (52.4% and 42.8%) were more pronounced in spontaneous and traumatic MEHs, respectively. Surgical approaches included- 1) Transmastoid, 2) Middle-cranial-fossa-approach (MCFA), 3) Combined and 4) Middle-ear- obliteration (MEO) techniques.  A total of 52.8% of COM/CHOL-MEHs and 49.1% of iatrogenic-MEHs underwent MEO.  MCFA was predominantly used in spontaneous-MEHs (52.5%) and traumatic-MEHs (38.1%). The defect was mostly single (75.2%).  Smaller, multiple, bilateral lesions were more common in spontaneous-MEHs with tegmen-tympani involvement (57.4%). Incorporating etiology into MEHs is a key-step which can be used as a guidance in choosing the right surgery. MEO is a part of armamentarium, and should be used whenever needed, if the objective is performing a definitive surgery.
