Marin-Amat's syndrome is a rare associated movement, wherein contraction of orbicularis oculi is brought about by opening of the jaw in association with aberrant regeneration of facial nerve. This is the opposite of the Marcus-Gunn phenomenon; hence it has also been called Inverted Marcus-Gunn Phenomenon. Moreover in this case the opened the mouth or moved the jaw, the eye would close. This phenomenon is congenital and the closure of the eye is due to inhibition of the levator palpebrae superioris. We present two cases, one acquired after the surgery of tuberculosus cervical adenitis and other congenital with reference to the presentation, course and treatment. This entity is rare in children, with few reported cases, although probably will be found more frequently if looked for carefully. The diagnosis is clinical and does not require additional tests, although EMG may be useful to demonstrate the synkinesis.
