STM32 Rotary Encoder Pulse Count

[JPanc.1]

Is it proper way to to count encoder pulses using rising/falling edge interrupt instead of using Timer in Encoder Mode??

Because in my application I need interrupt above 80000 pulse count. But here timer is of 16-bit (STM32F103C8T6) so it can only count up to 65535.

So please suggest me better option and help me to solve out this.

No. Use Encoder mode. Sample Encoder count so often that in all case less then 2^15 pulses have arrived. Use add difference to last count value to externak 32 bit variable.
