Carpal tunnel and palm sensation

Kaplan anatomy explains that palm sensation is not affected by carpal tunnel sydrome; the superficial palmar cutaneous branch of median nerve passes superficial to the carpal tunnel.

So, basically some branches of the nerve responsible for palm sensation does not go through the carpal tunnel, correct?

But then, Kaplan also explains under Carpel Tunnel Syndrome, "There is also sensory loss and numbness on the palmar surfaces of the lateral 3 1/2 digits."

I find these two conflicting. Can anyone help me out? Many thanks in advance.

Palmar surface of the fingers, not the palm of the hand.

Median provides cutaneous sensation to the lateral 3.5 digits whereas the nerve (the name escapes me) that provides cutaneous sensation to the palm passes superficial to the flexor retinaculum; therefore not in the tunnel and not susceptible to compression.
