Oral piercing is defined as the cosmetic piercing of the oral cavity for the insertion of objects such as rings, studs or pins where both ends of the jewelry are confined to the oral cavity.2,13,21 A needle is inserted to create an opening through which a decorative ornament may be worn (Figure 1).9
Oral piercings may also include the perioral area such as cheeks, nose and eyebrows. Perioral piercings are piercings where one end of the jewelry is intraoral and the other end penetrates the skin surface of the cheeks, upper/lower lip or the chin.2 An additional oral modification includes tongue splitting where the tongue is divided into 2 lateral halves, creating a ‘forked’ appearance.2,3,20 The tongue is the most common oral piercing site, followed by lips (including the labiomental groove and the philtrum), cheeks, lingual or maxillary labial frenum or some combination. Rarely, the uvula may be pierced.24 The uvula is seldom pierced as it is difficult to perform the piercing as well as place the jewelry. There are concerns with aspiration or swallowing of the jewelry both during the piercing process and subsequent wearing of the jewelry. Issues such as the gag reflex, throat irritation, risk of nausea and interference with swallowing also contribute to the rarity of uvula piercing (Figure 2).11,19
There are two types of tongue piercings: the dorsoventral and the dorsolateral.21 The dorsoventral tongue piercing is the most common and safer as it generally avoids most major blood vessels. The tongue is pierced in the midline just anterior to the lingual frenum and the jewelry is generally worn so there is a sphere on both the dorsal and ventral surfaces of the tongue (Figure 3).
The dorsolateral tongue piercing is not a safe procedure due to the tongue’s vascularity and is generally not performed by professional piercers. In this piercing, the 2 spheres of the jewelry are both on the dorsum of the tongue, close to the lateral borders and about half way anteroposteriorly. The curved barbell between the spheres curves ventrally and resurfaces dorsally (Figure 4).
The placement of a piercing may contribute to the name of the piercing.24 The labret is on the lower lip just above the labiomental crease (Figure 5).
A piercing on the upper lip, off center and resembling a beauty mark for which these women are known, includes the Madonna, on the right side, and the Monroe, on the left side (Figure 6).
A Medusa piercing is in the philtrum of the upper lip, centered and just below the nose (Figure 7).
A Smiley piercing pierces the maxillary labial frenum (Figure 8), a Frowny pierces the mandibular labial frenum (Figure 9) and a Web pierces the mandibular lingual frenum (Figure 10).
A Rhino piercing goes through the tip of the nose, and the result resembles a rhino horn (Figure 11).
