BACKGROUND: Fiberoptic tracheo-bronchoscopy is the most commonly used procedure for percutaneous dilational tracheotomy (PDT). However, PDT can be associated with major complications, including death. Furthermore it is unclear, whether the tracheal ring fractures may contribute to the development of tracheal stenosis after PDT nor whether tracheal ring fractures can be prevented by using a rigid endoscope for this procedure. The purpose of this study was to evaluate the feasibility of and the incidence of complications for PDT using the rigid tracheotomy endoscope (TED)...

An otherwise healthy 34-year-old man was referred to our ear, nose and throat (ENT) clinic for a bilateral maxillary radiologic opacity. This condition was accidentally discovered with a panoramic radiography performed during a follow-up visit after a bilateral endodontic treatment. The patient did not report any specific sinonasal symptom such as purulent nasal discharge, loss of smell and cough, apart from an unspecific sinus pressure. The CT scans showed a bilateral inflammatory process into the maxillary-ethmoidal sinuses and an iron-like density within the maxillary sinuses, while nasal endoscopy showed purulent discharge in the ostiomeatal complex...

BACKGROUND: More than 400,000 cases of oropharyngeal squamous cell carcinoma (OPSCC) are diagnosed each year worldwide and the incidence is rising, partly as a result of human papillomavirus. Human papillomavirus-associated OPSCC affects younger patients and often presents at a higher stage; however, it is associated with a better prognosis.Until recently, first-line management of OPSCC involved chemoradiotherapy, as research had demonstrated comparable survival outcomes when compared with open surgery, with significantly decreased morbidity...

Wullstein, the founder of modern microscopic ear surgery, already used an oto-endoscope intraoperatively. However, it is only after the recent development of modern video-endoscopy with high-definition, 4K, and 3‑dimensional imaging that endoscopically guided surgery of the middle ear is gaining some importance. Key ventilation routes like the isthmus tympani and the epitympanic diaphragm can be visualized far better using an endoscope than with a microscope. Going through the external meatus, surgery of middle ear pathologies is possible without external incision...

PURPOSE: Chronic maxillary atelectasis is characterized by unilateral spontaneous enophthalmos and hypoglobus due to increased orbital volume secondary to maxillary sinus inward deformation. Reformation of the sinus architecture and reconstruction of the orbit are key to a successful outcome. Here, we introduce a one-staged surgery that addresses both these goals. PATIENTS AND METHODS: We retrospectively reviewed 11 patients treated with one-stage orbital and sinus surgery...

BACKGROUND: Midface advancement is a keystone intervention in the treatment plan of syndromic hypoplasia of the midface. Although earlier authors had been using a combination of smaller incisions to acquire enough access to perform the different osteotomies, Tessier popularized the bicoronal incision. This approach can be time-consuming however and leaves an ear-to-ear scar. The authors describe an endoscopically assisted piezo-electric Le Fort III osteotomy performed through minimal invasive access...

Herein, we present the case of a previously healthy 54year-old female who developed several weeks of unilateral tinnitus and aural fullness. She subsequently underwent unilateral pressure equalization tube placement at an outside institution after exam demonstrated a middle ear effusion, conductive hearing loss and normal nasopharyngoscopy. Ultimately, an MRI revealed an occult mass in the infratemporal fossa (ITF), which was successfully removed via an endoscopic transnasal ITF approach. Following resection of a histopathologically confirmed benign neurofibroma, she reported complete resolution of her symptoms...

In last thirty years we have been observing significant development of an endoscopic treatment of pancreatic fluid collections, including transmural drainage of walled-off pancreatic necrosis. Simultaneously, the use of endotherapy in treatment of main pancreatic ducts disruptions has increased. Despite many publications available in current literature, concerning the endoscopic treatment of consequences of acute necrotizing pancreatitis, the role of transpapillary drainage in management of patients with pancreatic fluid collections and pancreatic duct disruption as an after-effect of severe acute pancreatitis remains unclear and is still a current problem...

Aims. Hidrocystomas are benign cystic growths of the apocrine and eccrine sweat glands. These cystic lesions have been well documented on the face, head, and neck, but rarely in the external auditory canal. Presentation of Case. A 67-year-old woman presented with a bluish cystic mass partially occluding the external auditory canal and interfering with hearing aid use. Lesion was excised completely via a transcanal endoscopic approach with excellent cosmetic results, no canal stenosis, and no recurrence at 1-year follow-up...

In contrast to other means of studying the epitymapnum, the endoscope allows unparallel access without disruption of anatomy. The aim of this study is to delineate the anatomy of the epitympanum through transcanal endoscopy. Systematic dissection of anatomic specimens. We performed systematic endoscopic dissection of 20 ears in 10 fresh frozen anatomical specimens. A detailed flow sheet was filled up documenting the status of the lateral attic folds, the tensor fold, the cog and the tensor folds, the supratubal recess, and the patency of the anterior and posterior isthmus...

The popularity of endoscopes has been expanding not only in diagnostics but also in therapeutics. The traditional septal surgery also has come under the purview of endoscopic surgery in the last few decades. Endoscopic septoplasty has definitely many advantages over the conventional procedure. But the only disadvantage of endoscopic surgery is that it is a single handed technique as the other hand is used for holding the endoscope which may compromise the overall surgical time as the hemostasis and suctioning of the surgical field off the blood cannot be done simultaneously, in addition to the surgeon fatigue associated with holding the endoscope in the left hand...

INTRODUCTION: The anterior epitympanum recess (AER) is a common place of the development of the cholesteatoma, which is why removal of the matrix from this area plays a key role in the surgical treatment of chronic otitis media. AIM: To evaluate the intraoperative visibility of AER in endoscopic optics in comparison to microscopic optics and to determine the prevalence of cholesteatoma in various types of construction of the AER. Study design: retrospective analysis of intraoperative search...

The aim of the present study was to describe the use of the endoscopic-assisted cochlear implantation in cases with an unsuccessful standard surgical technique because of not achieving adequate exposure to the round window (RW). Three patients with a bilateral profound hearing loss were operated using an endoscopic-assisted cochlear implant procedure at our tertiary university referral center between 2012 and 2014. In all of the patients, a retroauricular "c" shaped incision was performed and a subperiosteal pocket was created...

The lipomas of oropharynx, hypopharynx, and larynx are so rare that up to now approximately there have been 100 cases reported. The lipomas are slow-growing lesions that are capable of reaching considerable dimensions and are often detected at a late stage. The symptoms can vary both in dimension and in location, semiobstructing the aerodigestive tract or exerting compression on adjacent structure. In this case, the lesion, which originated from the piriform sinus, was removed endoscopically urgently due to obvious signs of tissue suffering caused by stretching of the pedicle as a result of displacement of the mass...

INTRODUCTION: Surgical simulators are designed to improve operative skills and patient safety. Transcanal Endoscopic Ear Surgery (TEES) is a relatively new surgical approach with a slow learning curve due to one-handed dissection. A reusable and customizable 3-dimensional (3D)-printed endoscopic ear surgery simulator may facilitate the development of surgical skills with high fidelity and low cost. Herein, we aim to design, fabricate, and test a low-cost and reusable 3D-printed TEES simulator...

Hyaluronic acid (HA) is involved in modulating inflammatory airway processes and mucociliary clearance. Some studies have tested the effectiveness of the topical administration of HA in patients with upper airway diseases with positive preliminary results. A prospective, single-blind, 1:1 randomised controlled study was performed to assess the efficacy and safety of the daily topical administration of 9 mg of sodium hyaluronate in 3 mL of a 0.9 % sodium saline solution on the basis of endoscopic and clinical parameters in children with chronic adenoiditis associated with recurrent acute otitis media and otitis media with effusion; age- and gender-matched children receiving normal 0...

The mammalian cochlea has historically resisted attempts at high-resolution, non-invasive imaging due to its small size, complex three-dimensional structure, and embedded location within the temporal bone. As a result, little is known about the relationship between an individual's cochlear pathology and hearing function, and otologists must rely on physiological testing and imaging methods that offer limited resolution to obtain information about the inner ear prior to performing surgery. Micro-optical coherence tomography (μOCT) is a non-invasive, low-coherence interferometric imaging technique capable of resolving cellular-level anatomic structures...
