Nose-picking, also known as rhinotillexomania in medical-speak, generally is a benign, sedentary (and private) solo activity, but when excessive, can lead to a number of medical problems including nosebleeds (25% of nose-pickers), septal perforation, staph infections, etc. In one extreme case, it even led to a self-inflicted ethmoidectomy (sinus surgery)!
Though most people pick their nose with their finger and use their fingernail to "dig" the golden nugget out, it is recommended to avoid use of the nail due to the danger of causing mucosal trauma (just like when itching the eye, use of the fingernail is not ideal). Using a saline nasal spray or saline flushes can help soften as well as minimize nasal crusting accumulation and enable one to "blow" the nasal boogers out. Humidification, especially when the air is cool and dry, is important to prevent hard nasal boogers from occurring in the first place. Nasal emollients like ponaris are also quite helpful as a preventative measure.
Now, it is a well-accepted fact that ENT physicians are the experts in removing unwanted nasal snot. So what's our secret?
Beyond our 5 years of surgical training, we have fancy equipment in order to obtain optimal visualization of nasal cavity. Use of a nasal speculum as shown below provides direct visualization of the entrance of the nose and suffices in most situations.
However, we are also skilled in the use of nasal endoscopic equipment to examine harder to visualize parts of the nasal cavity.
With visualization, we have at our disposal a large array of equipment that can be used for removal/retrieval. Our workhorse tool is the bayonet forcep. This tool is ideal for the hard nasal crusting in the front part of the nasal cavity.
