Bilateral Intranasal Supernumerary Teeth in a Non-Syndromic Adult: Clinicoradiological Findings on Computed Tomography — A Case Report
This case report describes the exceptionally rare presentation of bilateral intranasal supernumerary teeth in a non-syndromic adult, highlighting how non-contrast CT with bone window reconstruction provides definitive diagnosis by distinguishing dental structures from other nasal masses and guiding surgical planning.

Imagine your body as a bustling city, where every building has a specific job and a specific address. Teeth are like the city's streetlamps: they are supposed to stand firmly in the jaw, lighting up your smile and helping you chew. But sometimes, during the construction phase of a person's life, a streetlamp gets built in the wrong place entirely. In the world of medicine, this is called an "ectopic" tooth. While most people get their extra teeth (supernumerary teeth) stuck in their gums or mouth, a very rare few end up growing inside the nose. This is a bit like finding a fully grown oak tree sprouting out of a flower pot inside your living room. Doctors often mistake these strange intruders for rocks or hardened gunk because they feel hard and look white on scans, but knowing the difference is crucial. If you try to remove a rock, you might chip a wall; if you try to remove a tooth without knowing it's a tooth, you could damage the delicate roots and nerves nearby. Understanding exactly what these intruders are and where they hide helps doctors plan the perfect, gentle removal, turning a scary medical mystery into a straightforward cleanup job.
Now, let's dive into a fascinating case report by Dr. Debabrata Maitra, which tells the story of a 47-year-old man who walked into a hospital with a very specific problem: his left nostril was blocked, and he was having occasional nosebleeds. To the naked eye, and even through a camera inside his nose, it looked like a firm, bumpy lump sitting on the floor of his nose. It was so stubborn that it felt like a stone. But here is the twist: this wasn't a stone, and it wasn't just a one-time accident. When the doctors took a special 3D picture of his face called a Computed Tomography (CT) scan, they discovered something incredibly rare.
The scan revealed that this man had two extra teeth, one on each side of his nose, even though he only felt symptoms on the left. It's like finding two hidden treasure chests in a house, but only one of them is making a noise. The tooth on the left was the troublemaker. It measured 8 × 4 mm and was poking its head up into the nasal cavity, acting like a boulder blocking a hallway. The tooth on the right was a quiet observer; it measured 15 × 6 mm but was completely hidden inside the bone of the jaw, never breaking through to the nose, and causing zero problems.
What makes this story a medical detective triumph is how the doctors figured out what these lumps were without cutting anyone open. They used a CT scan, which is like a super-powered X-ray that can slice through the body and show the inside in 3D. When they looked at the "bone window" settings on the scan, they saw something magical: the lumps had the exact same "brightness" or density as tooth enamel. In fact, they measured between 1800 and 1900 Hounsfield units (a way doctors measure how dense something is). This is the same density as a real tooth's hard outer shell. Furthermore, the scan showed the internal structure of a tooth, including a tiny hollow space in the middle called a pulp cavity, which looks like the core of a tree.
This discovery was a game-changer. Before the scan, the lump could have been mistaken for a rhinolith (a calcified rock formed in the nose) or an osteoma (a benign bone growth). But those things don't have the organized, tooth-like structure or the specific "tooth-brightness" seen on the scan. The CT scan acted like a magnifying glass that said, "No, this isn't a rock; it's a tooth." Because the scan showed the tooth's roots and its relationship to the surrounding walls so clearly, the doctors could plan a precise surgery to remove the left tooth using a camera and tiny tools, without needing to make big cuts.
The paper also highlights a very important lesson: even though the patient only had symptoms on one side, the scan showed that the problem existed on both sides. The right tooth was hiding quietly, but it was there. The doctors decided to leave the right tooth alone for now because it wasn't causing any trouble and was safely tucked inside the bone, but they noted that it needs to be watched. This case proves that for people with strange nasal blockages, a CT scan is the best tool to tell the difference between a rock, a bone growth, and a tooth. It turns a confusing mystery into a clear map, ensuring that the right treatment is chosen and that no hidden surprises are left behind.
