Voldemort tem o sentido do olfato?

Quanto a saber se uma pessoa pode sentir o cheiro de coisas sem nariz, os especialistas dizem que será capaz de , mas sua capacidade de respirar será prejudicada.

Likewise, the nose funnels air (and smells) toward receptor neurons, * which sit behind the face and near the front of the brain. You can't really damage this odor-sensing area by slicing off cartilage. More likely, cutting off someone's nose will affect their breathing, which in turn affects their ability to smell. The front of the nose has two main functions: It guides airflow and filters out dust and other large particles. The nostrils direct incoming breaths up and over turbinates located behind the nose. These turbinates secrete moisture to humidify the air before it reaches the receptors. At the same time, particles get stuck in nasal mucus before dripping or getting sneezed out. Without a nose, you'd end up inhaling more dry, dusty air...

O artigo em questão trata especificamente de um caso real em que guerrilheiros do Taliban cortavam os narizes e ouvidos de motoristas suspeitos de entrar em conluio com o inimigo. Em um corpo moldado pela magia, Voldemort ainda pode ter cornetos trabalhando dentro de seu rosto, o que significaria que ele não teria nenhum problema.

A resposta parece ser "Muito bem, obrigado!" ¹

Você diz que Voldemort não tem muito nariz, mas ele claramente tem narinas funcionando:

The thin man stepped out of the cauldron, staring at Harry . . . and Harry stared back into the face that had haunted his nightmares for three years. Whiter than a skull, with wide, livid scarlet eyes and a nose that was flat as a snake’s with slits for nostrils . . .

Lord Voldemort had risen again.

Ele pode claramente inalar com suas narinas e ampliá-las quando necessário, como uma pessoa comum:

He put back his terrible face and sniffed, his slit-like nostrils widening.

“I smell guilt,” he said. “There is a stench of guilt upon the air.”

Suas narinas também respondem às emoções, como acontece com as pessoas comuns:

“A little break,” said Voldemort, the slit-like nostrils dilating with excitement, “a little pause . . . That hurt, didn't it, Harry? You don’t want me to do that again, do you?”
