My fiance had surgery for hydrocephalus about 4 years ago. The doctors performed a "third ventriculostomy" on my wife-to-be and put a cool titanium plate in her head :11: she now has "no physical restrictions" and is in good health, aside from marrying me that is are there any complications associated with diving and this illness? she recently passed her owc and aside from having water in her ear there were no problems. max depth of owc was 29 feet. thanks
