In 2010, a German study was published involving subjects with tongue piercings. The tongue piercing was used as part of a device designed to relieve obstructive sleep apnea.
Obstructive sleep apnea is a disorder affecting many individuals. Severely affected individuals may suffer from various long-term health issues: cardiovascular, neurological, etc.
Treatments or symptom relief range from the most invasive, surgery, to less invasive lifestyle habit improvements. Other treatments include using continuous positive airway pressure machines or tongue-retaining devices like this one, which uses a suction effect:

So, how was the piercing used to achieve this purpose?
The proposed device is quite simple. Using an elastic band, they fastened the tongue to a mandibular splint (the kind used for bruxism) via the tongue jewelry.
This way, the tongue would theoretically be pulled forward, preventing the back of the tongue from blocking the airway during sleep.

Since the subjects didn’t suffer from any related sleep disorder, not even snoring, the researchers interestingly made them drink alcohol before sleep, as it induces snoring by relaxing various muscles in the area — including the throat and tongue.
They also emphasized that they purposely chose people with existing tongue piercings to avoid “invasive procedures, such as fitting objects with a tongue implant”.
While the idea was interesting and clever, the results unfortunately showed no significant effect, as the back of the tongue was not sufficiently pulled forward by the device. Additionally, the sample size was small and only included 10 people.
With effective suction-based tongue-retaining devices for obstructive sleep apnea available, there’s no clear reason why someone would prefer a custom, tongue-piercing-based device to treat their condition.
However, having an existing tongue piercing — depending on its position — could prevent the use of regular retainers. It also seems plausible that a deep tongue split could potentially interfere with suction-based devices due to a continuous airway formed by the split.
No studies has focused on these specific subjects yet!
