Humorous Options:
* Nasoscopist: "Naso" (nose) + "Scopist" (one who examines)
* Rhinomaniac: "Rhino" (nose) + "Maniac" (obsessed)
* Snifferologist: "Sniff" + "Ologist" (someone who studies)
More Serious Options:
* Nasal Anthropologist: This could refer to someone studying the anthropological significance of nose shapes.
* Rhinoplastic Surgeon: While not focused on small noses specifically, this is a surgeon who specializes in nose surgery.
* Facial Morphologist: This is a broader term, encompassing the study of facial features, including noses.
Ultimately, the "best" compound word depends on the context and what you want to emphasize.
