A man who suffered an unexplained blocked nose for two years surprised doctors who found a tooth growing inside the nostrils.
The 59-year-old unidentified, who was undergoing surgery to eliminate the tooth, complained to doctors in Denmark about problems of nasal congestion, discharge and loss of smell.
The individual experienced a facial trauma when he was a child and caused a fracture in the jaw and noses.
However, doctors said there was no evidence that they would suggest repositioning after the incident was related to the nasal growth condition.
"Our patient probably had the intranasal tooth held for most of his life, but he had late symptoms," Dr. Milos Fuglsang wrote in BMJ Case Reports, which carried out the removal of teeth at the Aarhus University hospital.
After a computerized tomography, doctors decided to use an endoscope to perform surgical extraction.
The exact cause of the rare condition is not known, with only 23 patients identified from a previous study from 1959 to 2008.
The specialists believe that it could be due to traumas, cyst infections or developmental disorders such as the cleft lip or wet palate, but they do not have any obvious explanation for this particular case.
The problem can affect children and adults, but cases reported so far suggest that it is more common in men by 60%.
It seems that the removal procedure clarified the individual's blocked problems, with no new symptoms reported one month later.
