Let's solve the expression step by step:

\[
[(18 \times 5) - (8^2)] - 10
\]

1. First, calculate \( 18 \times 5 \):
\[
18 \times 5 = 90
\]

2. Then, calculate \( 8^2 \) (8 squared):
\[
8^2 = 64
\]

3. Subtract \( 64 \) from \( 90 \):
\[
90 - 64 = 26
\]

4. Finally, subtract \( 10 \) from \( 26 \):
\[
26 - 10 = 16
\]

The result of the expression is \( \boxed{16} \).
