Nasopharyngeal carcinoma (NPC) evolves most commonly from the pharyngeal recess posteromedial to the medial crura of the Eustachian tube opening in the nasopharynx. Therefore unilateral middle ear effusion with hearing loss is a common presenting symptom of NPC, and its presence in adult patients make physicians suspect NPC. Recently, we experienced a 72- year-old female patient with advanced NPC which invaded Eustachian tube and middle ear cavity. She had long standing chronic otitis media with large perforation of tympanic membrane. Because of tympanic membrane perforation, she did not have any Eustachian tube-related symptoms such as newly developing ear fullness or hearing loss and even the physician had overlooked the diagnosis of NPC. Her NPC was diagnosed at a very advanced stage after performing biopsy of middle ear tumor. This case report shows that NPC can present with very unusual findings like middle ear tumor.

The U.S. Army’s Official History of the Korean War, United States Army in the Korean War series is a standard work on the military operations of the U. S. Army and its allies during the Korean War. This 4 volumes study has great prestige in the English speaking world. But these studies have some problems. One of the problems is that this work didn't pay enough attention to the operations of the Army of the Republic of Korea. Ebb and Flow, the work of Billy C. Mossman and the last book of this series, also have the same problem. In Mossman’s work, the South Korean Army is depicted as an inexperienced and incapable organization. Of course, this kind of narrative has enough historical basis. But during the Korean War, the South Korean Army carried out some successful military operations. So it is very unrighteous to only focus on the negative aspect of the South Korean Army. There is a need for more balanced works about the Korean War. .

The canal wall down mastoidectomy can secure a good operation field and remove the pathology easily, but it accompanies a cavity problem. To reduce the cavity problem, mastoid obliteration is conducted using multiple materials. And proper hemostasis is an important prerequisite for a successful outcome in all operative fields. TachoSil ® is used in many surgical specialties, especially for diffuse bleeding. TachoSil® is not only used for hemostasis but also for closure of other anatomical structures. Recently, we experienced two patients with recurred huge cholesteatoma of middle ear. They underwent canal wall down tympanomastoidectomy with mastoid obliteration using the TachoSil® due to the exposure of dura was observed removing the huge cholesteatoma completely. These two cases report show the successful treatment of recurred huge cholesteatoma, for which no recurrence is shown.
