BACKGROUND: Although cases of multiple primary malignant neoplasms are increasing, reports of more than three or four primary metachronous malignant neoplasms are extremely rare. Moreover, very few publications have provided a genetic mutational analysis or have evaluated risk factors associated with such neoplasms. We present an extremely rare case of nine primary malignant lesions in a man who was successfully treated. We also report on microsatellite stability status, analyze risk factors, and discuss the relevant literature...

PURPOSE: To anatomically describe a cartilaginous cap attached to the lateral process of the malleus. STUDY DESIGN: Histologic and gross anatomic review. METHODS: Twenty temporal bones were histologically reviewed. The anatomical relationship between the tympanic membrane and malleus was then defined at the level of the lateral process of the malleus and the long process of the malleus. Separately, gross evaluation of these levels at the macroscopic level was undertaken through endoscopic imaging in five subjects...

This paper presents a novel miniature robotic endoscope that is small enough to pass through the Eustachian tube and provide visualization of the middle ear (ME). The device features a miniature bending tip previously conceived of as a small-scale robotic wrist that has been adapted to carry and aim a small chip-tip camera and fiber optic light sources. The motivation for trans-Eustachian tube ME inspection is to provide a natural-orifice-based route to the ME that does not require cutting or lifting the eardrum, as is currently required...

Objectives: Our aim was to present our endoscope-assisted cochlear implantation (CI) technique, in which the middle ear landmarks were identified through the facial recess exposure by using an endoscopic view without elevating the tympanic annulus. The secondary goal was to assess whether the situation of difficult surgical exposure could be predicted by evaluating preoperative axial computed tomography (CT) examinations. Methods: CT examinations and surgical outcomes of endoscope-assisted CI surgeries were analyzed...

REVIEW
Hans Scherübl, Guillaume Cadiot
Neuroendocrine neoplasias (NEN) of the stomach, duodenum, pancreas, appendix, or rectum that are ≤1 cm in size as well as well-differentiated with World Health Organization grade 1 (G1) can be considered 'early' neuroendocrine tumors; they have a very good prognosis. Regarding prognosis, neuroendocrine tumors (NET) G1 must be distinguished from well-differentiated NET G2 and poorly differentiated neuroendocrine carcinomas (NEC) G3. NET are increasing, with a rise in the age-adjusted incidence in the USA by about 700% in the last 40 years...

OBJECTIVES: Despite the worldwide availability of endoscope in otology, it still has not replaced the microscopic surgery as it has for nose surgery. In 2008, we administered a questionnaire on the preference of using otoscopes in Korea. In light of the worldwide availability of endoscopic ear surgery, we have now conducted a more detailed survey to determine if this preference has changed over 8years. SUBJECTS AND METHODS: A questionnaire consisting of 10 questions was used to survey members of the Korean Otological Society who were actively performing middle ear surgery...

BACKGROUND: Endoscopic ear surgery is becoming an accepted technique in otological surgery, in the management of chronic otitis media. METHODS: The technique was introduced to the humanitarian care setting of an ear camp in Nepal to consider the appropriateness of the technique in this type of clinical setting. RESULTS: Fifteen cases of myringoplasty were successfully completed. CONCLUSION: The apparent advantages of the endoscopic approach over the traditional microscopic one were the ease of transporting the equipment and the optimal view obtained of the tympanic membrane...

INTRODUCTION: Most of traumatic tympanic membrane perforations have inverted or everted edges, however, the effects of inverted and everted edges on the spontaneous healing of the eardrum remain controversial. OBJECTIVE: We investigated the influence of inverted or everted edges on the spontaneous healing of traumatic tympanic membrane perforations. METHODS: The clinical records of patients with a traumatic tympanic membrane perforations who met the study criteria were retrieved and categorized into two groups, based on whether the eardrum was inverted or everted...

OBJECTIVE: Conventional otoscopes and oto-endoscopes, which are used to examine the tympanic membrane (TM), do not provide tomographic information. Optical coherence tomography (OCT) non-invasively reveals the depth-resolved internal microstructure of the TM with very high spatial resolution. We designed this study to examine the TMs with middle ear diseases using a handheld otoscope employing 860 nm spectral domain (SD)-OCT, combined with video camera and to demonstrate the clinical applicability of this system...

Transcanal endoscopic ear surgery (TEES) will become a very useful therapeutic option. A perilymphatic fistula (PLF) is defined as sudden sensorineural hearing loss and/or vertigo caused by leakage of the perilymph through a fistula from the oval window and/or round window. We report a case of PLF after electric acoustic stimulation (EAS), a kind of cochlear implant, successfully treated by TEES. A 38-year-old man presented to our hospital with vertigo and hearing loss (HL). His vertigo was induced by Valsalva maneuvers...

OBJECTIVES/HYPOTHESIS: Endonasal surgeries are the primary cause of septal perforation (SP). However, trauma, inflammation, infections, neoplasms, or abuse of inhaled drugs can also cause SP. Septal repair is indicated in patients who experience nasal obstruction, crusting, intermittent epistaxis, purulent discharge, or nasal whistling and in those who fail conservative treatment. Multiple approaches have been suggested to repair the SP; however, none has been universally adopted. This study explores the feasibility of repairing a total SP using the pericranial flap (PCF)...

The advent of the endoscope has facilitated otological surgery in recent years. Advances in optical technology have led to the development of high definition visualisation, such as 4K magnification. Narrow band imaging (NBI) has been shown to improve visualisation of tissue based on varying degrees of vascularity. This is a feasibility study, the first of its kind, aiming to investigate the appearances of middle ear anatomy and pathology (tympanic membrane, tympanosclerosis, cholesteatoma, granulation, endolymphatic sac hydrops, otosclerosis) under the NBI filter, using a high definition 4K endoscope...
