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...

Mubarak M Khan, Sapna R Parab
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: 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...

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...

Introduction. Bloom syndrome (BS) is an inherited disorder due to mutation in BLM gene. The diagnosis of BS should be considered in patients with growth retardation of prenatal onset, a photosensitive rash in a butterfly distribution over the cheeks, and an increased risk of cancer at an early age. Clinical manifestations also include short stature, dolichocephaly, prominent ears, micrognathia, malar hypoplasia and a high-pitched voice, immunodeficiency, type II diabetes, and hypogonadism associated with male infertility and female subfertility...

BACKGROUND: Compared with surgical resection, endoscopic transsphenoidal surgery (TSS) for cholesterol granuloma (CG) in the petrous apex (PA) is associated with local recurrence due to obstruction of the drainage route. We present a detailed procedure of an endoscopic TSS using pedicle vascularized nasoseptal flap (PVNF). METHODS: A 40-year-old woman with a history of repeated surgery for left tympanitis was referred to our institution. Neurological examination revealed severe hearing loss in the left ear...

Endoscopic ear surgery (EES) provides several advantages compared with traditional binocular microscopy, including a wide-field view, improved resolution with high magnification, and visual access to hidden corridors of the middle ear. Although binocular microscopic-assisted surgical techniques remain the gold standard for most otologists, EES is slowly emerging as a viable alternative for performing otologic surgery at several centers in the United States and abroad. In this review, we evaluate the current body of literature regarding EES outcomes, summarize our EES outcomes at the Massachusetts Eye and Ear Infirmary, and compare these results with data for microscopic-assisted otologic surgery...

The main application of endoscopic surgery relies on the middle ear cholesteatoma surgical treatment, although for a definitive validation and acceptance by scientific community, long-term results are needed about recurrent and residual rates of the pathology. The aim of the present paper was to analyze the single institution experience with the long-term results of surgical treatment of attic cholesteatoma.

The endoscope has transformed the way we observe, understand, and treat chronic ear disease. Improved view, exclusive transcanal techniques, assessment of ventilation routes and mastoid tissue preservation have led to decreased morbidity and functional enhancement of minimally invasive reconstruction of the middle ear. The philosophical identity of endoscopic ear surgery is evolving; new research, long-term results, and widespread acknowledgement of its postulates will undoubtedly define its role in otology...

Paralleling the introduction of endoscopes for sinus surgery more than two decades ago, otology is facing a similar paradigm shift in the use of endoscopes to perform ear surgery. The wide-angle and high-resolution image provided by endoscopes allows for improved visualization of the tympanic cavity using minimally invasive surgical portals. Incorporating endoscopic ear surgery into otologic practice is challenging. A graduated and step-wise introduction of EES to otologic surgery is recommended to ensure safe and successful implementation...

There are limited studies describing the surgical and hearing outcomes following endoscopic stapes surgeries, despite the burgeoning interest and excitement in endoscopic ear surgery. Current studies have demonstrated that endoscopic stapes surgery is safe and has similar audiologic outcomes when compared with microscopic stapes procedures. However, preliminary studies show decreased postoperative pain in endoscopic cases compared with microscopic controls. In regards to possible endoscopic advantages, these few studies demonstrate mixed results when comparing the need to remove the bony medial external auditory canal wall to improve visualization and access to the oval window niche...
