A Case of Supernumerary Tooth in Tonsil / 대한이비인후과학회지

The supernumerary teeth mean excessive teeth that appear in addition to the regular number of teeth and occur in a wide variety of sites. Mesiodens, which is a malformed, peg like tooth that occurs between the maxillary central incisor is most common. The next common site is the fourth molar and lateral incisors. Tonsil as a site of supernumerary teeth is rare, however, we experienced one such case of an ectopic supernumerary tooth embedded in tonsil.

A Case of Multiple Hypoglossal Neurilemmomas in the Submandibular Space / 대한이비인후과학회지

Neurilemmoma is a benign tumor which is known to originate from the myelin-producing Schwann cells of the spinal nerve root, peripheral nerve and all kinds of cranial nerves except the optic nerve and olfactory nerve. Approximately, 25% to 40% of all neurilemmomas are found in the neural structures of the head and neck. Neurilemmoma of the 12th cranial nerve is rare ; multiple neurilemmoma is even more rare. Recently, the authors experienced a case of multiple (x3) hypoglossal neurilemmoma in the submandibular space. The tumor was removed completely and verified histopathologically as neurilemmoma.
