On November 8, information from Bac Giang Obstetrics and Pediatrics Hospital said that recently, doctors from the hospital's Interdisciplinary Department received and treated a child patient with a misplaced tooth on the floor of the right nose.

Accordingly, baby N.D.D (4 ​​years old, residing in Tan Lieu commune, Yen Dung district, Bac Giang province) was taken to the hospital due to frequent nasal congestion.

The patient's family said that for about a year now, the child has been experiencing nosebleeds and frequent nasal congestion. The family took the child to a nearby medical facility for examination but found no abnormalities. Despite taking the prescribed medication, the child continued to have nosebleeds, so the family decided to take the child to a higher level for examination.

At Bac Giang Obstetrics and Pediatrics Hospital, after examination, doctors discovered that the child's right nasal cavity had a mass protruding from the nasal floor; the nasal floor and the gap between the two sides had a lot of pus.

The child was indicated for nasal endoscopy along with the results of a CT scan of the nose and sinuses. The doctors consulted and agreed to diagnose the child with acute sinusitis/right nasal floor mass with suspected ectopic supernumerary teeth.

After 1 week of stable medical treatment for acute sinusitis, the doctors decided to perform endoscopic surgery to remove the misplaced extra tooth.

After surgery, the patient's health was stable and there were no more nosebleeds or stuffy nose.

Dr. Tran Minh Tan - Interdisciplinary Department, Bac Giang Obstetrics and Pediatrics Hospital said that through documents, there is no clear cause for tooth buds not growing in the correct position in the dental arch but growing in other positions such as: in the palate, inside or outside the dental arch, in the sinuses and on the floor of the nose, forming misplaced teeth.

However, there are also some causes mentioned such as: Dental trauma, maxillary osteomyelitis, development of a cleft palate defect and genetic factors.

Ectopic teeth growing in the floor of the nose is a very rare case, in this case the tooth germ does not point down but up to the floor of the nose so the tooth develops into the nasal cavity. This is an extra tooth while all the other teeth are still developing normally.

According to Dr. Tan, in medical literature, there were only 23 cases of teeth growing out of place in the floor of the nose recorded in the period from 1959 to 2008. Patients often have no symptoms and only accidentally discover it when they go for a check-up.

Depending on the location of the misaligned tooth, there may be symptoms such as: stuffy nose, runny nose, nosebleed, headache... symptoms are usually unilateral, do not respond to medical treatment and recur frequently.

If the tooth is not surgically extracted in time, the condition will become more and more serious, causing complications. Therefore, early diagnosis and timely treatment are extremely necessary to ensure the health and safety of children.
