Several doctors had believed that it was either allergic rhinitis or sinusitis, the inflammation of cavities around the nasal passages, that had caused a 20-year-old man from Taoyuan County to suffer frequently from a blocked or runny nose — until they found a tooth in his nasal cavity.
Taoyuan General Hospital’s ear nose and throat department director Cheng Chueh-yi (鄭爵儀) on Saturday discussed the recent case, in which the patient had suffered from chronic congestion in and discharge from his left nasal passage for years and all the doctors he saw diagnosed him with either allergic rhinitis or sinusitis.
“However, none of the physicians had managed to cure the conditions that the patient said had severely affected his sleep, his daily life and relationship with others,” Cheng said.
Cheng first performed a nasal endoscopy on the man and only found a polyp in his left nasal cavity.
It was only after Cheng arranged a computed tomography scan of the patient’s nose that he discovered a 1cm tooth hidden in his maxillary sinus, a pyramidal cavity whose base is formed by the lateral wall of the nasal cavity.
“We presume that the ectopically erupted tooth has existed in the man’s nasal cavity for several years, causing inflammation of the surrounding tissues that eventually led to the uncomfortable symptoms,” Cheng said.
Cheng said that because the man had all his adult teeth, it was most likely that the misplaced tooth was actually an extra tooth developed during puberty that grew upward into the nasal cavity due to pressure from neighboring teeth.
“The patient’s symptoms have improved significantly after the tooth was surgically removed,” Cheng said.
In some cases, ectopically erupted teeth straddle both the oral and nasal cavities, while in other situations, they form entirely within the nose, Cheng said, adding that common symptoms include unilateral nosebleeds, as well as nasal discharge or congestion.
AGING: While Japan has 22 submarines, Taiwan only operates four, two of which were commissioned by the US in 1945 and 1946, and transferred to Taiwan in 1973 Taiwan would need at least 12 submarines to reach modern fleet capabilities, CSBC Corp, Taiwan chairman Chen Cheng-hung (陳政宏) said in an interview broadcast on Friday, citing a US assessment. CSBC is testing the nation’s first indigenous defense submarine, the Hai Kun (海鯤, Narwhal), which is scheduled to be delivered to the navy next month or in July. The Hai Kun has completed torpedo-firing tests and is scheduled to undergo overnight sea trials, Chen said on an SET TV military affairs program. Taiwan would require at least 12 submarines to establish a modern submarine force after assessing the nation’s operational environment and defense
A white king snake that frightened passengers and caused a stir on a Taipei MRT train on Friday evening has been claimed by its owner, who would be fined, Taipei Rapid Transit Corp (TRTC) said yesterday. A person on Threads posted that he thought he was lucky to find an empty row of seats on Friday after boarding a train on the Bannan (Blue) Line, only to spot a white snake with black stripes after sitting down. Startled, he jumped up, he wrote, describing the encounter as “terrifying.” “Taipei’s rat control plan: Release snakes on the metro,” one person wrote in reply, referring
The coast guard today said that it had disrupted "illegal" operations by a Chinese research ship in waters close to the nation and driven it away, part of what Taipei sees a provocative pattern of China's stepped up maritime activities. The coast guard said that it on Thursday last week detected the Chinese ship Tongji (同濟號), which was commissioned only last year, 29 nautical miles (54km) southeast of the southern tip of Taiwan, although just outside restricted waters. The ship was observed lowering ropes into the water, suspected to be the deployment of scientific instruments for "illegal" survey operations, and the coast
An inauguration ceremony was held yesterday for the Danjiang Bridge, the world’s longest single-mast asymmetric cable-stayed bridge, ahead of its official opening to traffic on Tuesday, marking a major milestone after nearly three decades of planning and construction. At the ceremony in New Taipei City attended by President William Lai (賴清德), Premier Cho Jung-tai (卓榮泰), Minister of Transportation and Communications Chen Shih-kai (陳世凱) and New Taipei City Mayor Hou Yu-ih (侯友宜), the bridge was hailed as both an engineering landmark and a long-awaited regional transport link connecting Tamsui (淡水) and Bali (八里)
