OBJECTIVES: Endoscopic ear surgery is a rapidly developing field with many advantages. But endoscopes can reach temperatures of over 110 C at the tip, raising safety concerns. Reducing the intensity of the light source reduces temperatures produced. However, quality of images at lower light intensities has not yet been studied. We set out to study the effect of light intensity on image quality in EES. DESIGN: Prospective study of patients undergoing EES from April to October 2016...

BACKGROUND: Untreated chronic otitis media severely impairs quality of life in affected individuals. Local destruction of the middle ear and subsequent loss of hearing are common sequelae, and currently available treatments provide limited relief. Therefore, the objectives of this study were to evaluate the feasibility of the insertion of a coronary stent from the nasopharynx into the Eustachian tube in-vivo in sheep and to make an initial assessment of its positional stability, tolerance by the animal, and possible tissue reactions...

A 58-year-old female complained earfullness and otalgia and came to the clinic. Dark gray colored cystic mass obstructing the left ear canal was observed during the endoscopic exam. Contrast enhanced CT image showed an oval shape soft tissue lesion in the mid part of the external auditory canal with a homogenous increased contrast uptake. The mass was removed under microscopic view at outpatient clinic. While dissecting the mass in the ear canal, a pod like structure was visualized. The external organism was densely adherent to the skin and turned out to be an engorged hard tick...

Nowadays we use novel diagnostic equipment for lung cancer. Bronchoscopy was the tip of the arrow for diagnosis, however; ultrasound systems have brought a revolution. We have the radial-endobronchial ultrasound for peripheral lesions and the convex probe endobronchial ultrasound for central lesions. Ultrasound endoscopic systems can be used for the diagnosis of any lesion that can be approached from the airways. In the current manuscript we will present two methods for the biopsy of thyroid gland. The first method is using anesthisiological tools and the second tools from the ear, nose and throat department...

A highly phase stable hand-held (HH) endoscopic system has been developed for optical coherence tomography and vibrometry. Designed to transit the ear canal to the middle ear space and peer through the round window (RW), it is capable of imaging the vibratory function of the cochlear soft tissues with subnanometer scale sensitivity. A side-looking, 9 cm long rigid endoscope with a distal diameter of 1.2 mm, was able to fit within the RW niche and provide imaging access. The phase stability was achieved in part by fully integrating a Michelson interferometer into the HH device...

Natasha Pollak, Resha S Soni
Tympanic paragangliomas are uncommon vascular tumors of neural crest origin. Classically these lesions have been surgically managed via a transcanal or transmastoid approach using binocular microscopy. We describe a case in which a tympanic paraganglioma was removed via a transcanal approach, using the endoscope exclusively. Endoscopic ear surgery enhances visualization, helping to ensure complete tumor removal, while reducing unnecessary dissection and its associated morbidity. For small middle ear neoplasms, a purely endoscopic approach is feasible, with excellent results...

Hamed Sajjadi
Attic cholesteatoma with antral extension in tight sclerotic mastoid cavities is a common presentation that creates difficult decision-making intraoperatively. Drilling through a sclerotic and small mastoid cavity, keeping the canal wall intactis often difficult and increases the risk of serious injury. Consequently, a canal-wall-down mastoidectomy is often performed. The endoscopic transcanal modified canal-wall-down mastoidectomy approach allows the benefits of an open cavity for cholesteatoma resection and the benefits of a closed cavity for better long-term care and a more normal ear canal and middle ear reconstruction...

Objective: The purpose of this study is to evaluate our experience with endoscopic repair of ossicular discontinuity at the incudostapedial joint, with or without an intact stapes suprastructure, and present our hearing results. We classify results based on the causative pathology, the type of ossiculoplasty, and type of lesion. We demonstrate the ability to endoscopically place a total ossicular replacement prosthesis (TORP), measuring 4.25 mm, between the stapes footplate and the incus remnant to reestablish ossicular continuity...

REVIEW
Razan A Basonbul, Michael S Cohen
Tympanic membrane perforationsoccur frequently in children, and can result in hearing loss, otorrhea, pain, and cholesteatoma. Due to the narrower ear canal in children, a postauricular incision is often needed to access the tympanic membrane for surgical repair. Endoscopic approaches are increasingly being used for tympanic membrane repair, reducing the need for postauricular incisions. As the need for a postauricular incision decreases, the demand for non-autologous grafting material has increased. Acellular porcine small intestinal submucosa (SIS) has been described in the literature as an alternative to commonly used autologous grafts, and is well suited for use with transcanal endoscopic ear surgery as a minimally invasive approach...

The development of endoscopic ear surgery techniques promises to change the way we approach ear surgery. In this review paper, we explore the current evidence, seek to determine the advantages of endoscopic ear surgery, and see if these advantages are both measureable and meaningful. The wide field of view of the endoscope allows the surgeon to better visualize the various recesses of the middle ear cleft. Endoscopes make it possible to address the target pathology transcanal, while minimizing dissection or normal tissue done purely for exposure, leading to the evolution of minimally-invasive ear surgery and reducing morbidity...
