those bald patches? Low down? Maybe at the base? Animals, exhaust fumes if cars parked there
when you cut out the bald patches it may be wise to wait until you see shoots and cut to those in spring.
difficult to say if "terminal" ...are the bald areas spreading?
replacements? Lonicera nitIda Baggesons Gold is an easy olive turning yellow foliage in summer.
if the main hedge is fine how about inter planting with a foliage plant or two....if you are sure the bald areas cannot be restored.
Any hedge is best trimmed so that the base is wider than the top. This encourages densely growing lower growth
