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...

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, 4‑k, 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 diaphragma can be visualized far better by using an endoscope rather than a microscope. Going through the external meatus surgery of middle ear pathologies is possible without external incision...

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...

Endoscopic technique allows visualization of the protympanic segment of the eustachian tube in patients undergoing chronic ear surgery. Balloon dilatation of the area can be undertaken with clear widening of the obstructed areas. This article discusses the authors' approach and experience with transtympanic dilatation of the eustachian tube. It includes case selection, technique, immediate postprocedure evaluation, and results, with multiple case presentations and videos.

INTRODUCTION: Few centers, mainly located in urban settings offer otological surgical services, yet majority of patients requiring these services are rural based and are generally unable to access these centers with resulting disease chronicity and complications. This paper aims to describe the access of otological surgical services by a rural population. METHODOLOGY: This is a retrospective study of patients who accessed otological services at three secondary health institutions and one tertiary referral institution...

PURPOSE OF REVIEW: Total endoscopic ear surgery is becoming more popular given the improved visualization of the middle ear and its related pathology as compared to the microscope. Whereas the endoscope has been used for close to two decades in cholesteatoma surgery with several significant studies, few studies have outlined the surgical outcomes, and also the complications, in patients undergoing endoscopic tympanoplasties and stapes surgeries. This review highlights those few studies...

OBJECTIVE: Endoscopic procedures are becoming common in middle ear surgery. Inflammation due to chronic ear disease can cause bony erosion of the carotid artery and Fallopian canals, making them more vulnerable during surgery. The objective of this study was to determine whether or not chronic ear disease increases dehiscence of the carotid artery and Fallopian canals. DESIGN: Comparative human temporal bone study. SETTING: Otopathology laboratory...

PURPOSE OF REVIEW: The aim of this review is to study the rationale, limitations, techniques, and long-term outcomes of endoscopic ear surgery. RECENT FINDINGS: The article discusses the advantages of endoscopic ear surgery in treating cholesteatoma and how the hidden sites like facial recess, sinus tympani, and anterior epitympanum are easily accessed using the endoscope. SUMMARY: Transcanal endoscopic approach allows minimally invasive removal of cholesteatoma with results that compare well to traditional postauricular tympanomastoidectomy...
