Common Bleeding Sites of Posterior Epistaxis: Nasal Endoscopic Study / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: Typically, posterior epistaxis means that the bleeding point cannot be visualized with anterior rhinoscopy, and it is difficult to find a localized bleeding point. Although bleeding point identification is the key to efficient management, debate and uncertainty remain around the actual location and distribution of the bleeding sites in posterior epistaxis. SUBJECTS AND METHOD: This study was designed to clarify bleeding points of the posterior epistaxis using nasal endoscopy. In 121 of the total 150 (80.7%) cases, we could see the posterior nasal cavity in more detail and find the bleeding point precisely. RESULTS: The most common sites of the bleeding were the posterior portion of the inferior meatus, the posterior portion of middle meatus, and the posterior septum medial to the middle turbinate in order of frequency. A total of 113 cases, corresponding to 93.4% (113/121), showed that epistaxis could be controlled very efficiently by electrocauterization and localized small packing with the help of endoscopes. In the majority of cases, non-surgical interventions were sufficient. CONCLUSION: Bleeding could be stopped more rapidly and with less discomfort if checking the 3 most common sites early.

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.
