A knife victim needed 90 stitches after her attacker "targeted" her face and head, a court heard.
Shane Cartledge inflicted a gaping wound to her left cheek and a similar wound to her forehead.
He cut the right side of her mouth, cut into her right ear and stabbed her in her right shoulder.
A jury, who convicted Cartledge of wounding with intent to cause grievous bodily harm on December 21, 2021, saw the shocking photographs of her injuries taken in the aftermath - injuries which leave her with nightmares.
Cartledge's defence at his trial had been that the victim attacked him with the knife and her injuries were caused accidentally as he struggled to gain control of the weapon.
But the jury had been sure he deliberately inflicted those nasty injuries and convicted him.
"There was a use of a knife targeted at her face," said Gregory Dickinson QC, the Recorder of Nottingham, as the defendant returned to Nottingham Crown Court to be sentenced on Friday, February 18.
Cartledge, 38, of Crich View, Newton, Alfreton, Derbyshire, was sentenced to 11 years, with a requirement to serve two-thirds.
He had been in a relationship with the victim's sister. There was a family fallout.
The victim later went to her sister's home with her father but not to attack her or cause trouble, the court heard.
But Cartledge, who was at the property in Mansfield, responded by picking up a knife from the kitchen on January 23, 2020.
He went outside and attacked the woman, principally to her face, and left her requiring operations needing 80 to 90 stitches.
She was in hospital for three days and spent nine weeks off work.
Now with permanent scarring and nerve damage around her right eyebrow, she said she has crippling anxiety.
"The thought of doing my weekly shopping, carrying out my daily errands or answering the phone, fills me with crippling anxiety but, on some occasions, I avoid going out altogether," her statement read.
She is forever reminded of what the defendant did by her reflection in the mirror.
She has a recurring nightmare she described as a "fragmented replay of that day".
When she learned he had been found guilty, the news started her healing process.
