Mubarak M Khan, Sapna R Parab
OBJECTIVES/HYPOTHESIS: Endoscopic ear surgery provides a minimally invasive approach to the middle ear. The disadvantage of endoscopic ear surgery is that it is a single-handed surgical technique. The nondominant hand of the surgeon is utilized for holding and manipulating the endoscope. This necessitated the need for the development of an endoscope holder that would allow both hands to be free for surgical manipulation. The aim of this article is to report our preliminary experience using our newly designed and developed endoscope holder, which allowed us to perform cartilage tympanoplasty utilizing both hands for surgery...

INTRODUCTION: Transcanal myringoplasty has the advantages of demanding lower operative time and minimal external incisions. It can be performed using the microscopic or endoscopic approach. In the last decade, the use of endoscopes in ear surgery has increased significantly. This technique may allow "around the corner" visualization of small recesses, through narrow spaces, without the aid of canalplasty in unfavorable ear canals. OBJECTIVE: To describe a case series of transcanal endoscopic myringoplasty performed in a university service...

OBJECTIVE: Routine endoscopic examination during primary surgery decreased the rate of residual cholesteatoma to 18% in our early experience. Based on this, we stopped performing routine second-look surgery in children who were endoscopically free of cholesteatoma at the end of primary surgery. We sought to investigate if second-look procedures after endoscopic-assisted surgery could safely be performed only in children at a high risk of residual disease (extensive inflammation, spontaneously ruptured or fragmented cholesteatoma, residual disease intentionally left)...

OBJECTIVES: To evaluate the results of a newly introduced technique to our Department of endoscopic assisted transcanal myringoplasty applied in tympanic membrane perforation in children of any age and compare them to that of the previously standard microscopic assisted myringoplasty technique. METHODS: A retrospective study of myringoplasties performed between January 2005 and June 2014 in children suffering from chronic otitis media with perforation. In microscope-assisted cases, a transcanal approach was applied when the anterior tympanic annulus was completely visible through the ear speculum, and a postauricular approach was used in all other cases...

The objective of this work was to study the effect of nocturnal intermittent hypoxia on auditory function of simple snoring patients and subjects affected by OSAS; we compared the audiologic profile with the severity of OSAS to detect early signs of cochlear damage. One hundred-sixty patients underwent overnight polysomnography, micro-otoscopy, multi-frequency audiometry, acufenometry, TEOAE recording and d-ROMs test. All subjects were divided in four groups, based on presence/absence of AHI (simple snoring without OSAS, mild OSAS, moderate OSAS, severe OSAS)...

Transcanal endoscopic ear surgery (EES) provides a high-resolution, wide-field view of the middle ear compared with the conventional operating microscope, reducing the need for a postauricular incision or mastoidectomy. Our group has shown in cadaveric human temporal bone studies that radiant energy from the endoscope tip can quickly elevate temperatures of the tympanic cavity. Elevated temperatures of the middle ear are associated with acute auditory brainstem response shifts in animal models. In EES, proposed methods to decrease middle ear temperature include frequent removal of the endoscope and the use of suction to rapidly dissipate heat; however, the routine application of such cooling techniques remains unknown...

Many difficulties might be encountered during conventional stapes surgery. However, the good exposure provided by the endoscope can facilitate this procedure. The present study addresses the effectiveness of endoscopic stapes surgery with regard to the operation time and patients' convenience and satisfaction. 19 patients underwent endoscopic stapes surgery without packing. 15 patients who experienced the microscopic stapes surgery served as the comparison group. Audiometric results and the patients' satisfaction as measured by visual analog scale in both group were compared...

Lela Migirov, Michael Wolf
BACKGROUND: Myringoplasty can be technically difficult in the pediatric patients due to the narrowness of the external auditory canal and the generally small size of the ear. Moreover, temporalis fascia grafts and myringoplasties for anterior perforations are more likely to fail in children. Surgical management of anterior perforations requires total exposure of the anterior angle however a microscope may fail to provide a view of the anterior edge in most of perforations. Recently, different endoscopes are used in the performance of ear surgery in general and myringoplasty in particular...

OBJECTIVES/HYPOTHESIS: Although the theoretical risk of elevated temperatures during endoscopic ear surgery has been reported previously, neither temperature change nor heat distribution associated with the endoscope has been quantified. In this study, we measure temperature changes during rigid middle ear endoscopy in a human temporal bone model and investigate whether suction can act as a significant cooling mechanism. STUDY DESIGN: Human temporal bone model of endoscopic middle ear surgery...
