Rationale for Endoscopic Ear Surgery

In clear contrast to the impact of the introduction of endoscope in most surgical disciplines, the practice of ear surgery has changed little and it continues to be the domain for the microscope. Depending on the task at hand, there are many distinctions that would make the endoscope a better instrument than the microscope and vice versa. We all need to master working with both instruments to better understand and treat pathologies of the ear. The objective of this group and this web site is to neutralize these longstanding biases toward the microscope and to get all of us to use the best instrument in the best way possible to help our patients.

The ability to place the surgeons eyes within the ear cavity using angled endoscopes, allows the operator a contextual understanding of the anatomy that is difficult to match using the microscope.  The disease/ anatomical interface is better appreciated.  This improved anatomical understanding, in turn provides confidence in surgical procedures both endoscopically and microscopically.

When compared to the microscope, two distinct advantages are present with the endoscope.

  1. The Objective lens is placed within the ear canal or middle ear, which allows for an all-encompassing contextual view of the disease/ anatomy interface.  In contrast, the traditional microscopic method relies on removal of significant amounts of normal bone and soft tissue, often with removal of intact structures to fully observe the disease extent.
  2. The live image used by the surgeon is the same one that everyone else in the operating room is observing. This simultaneous viewing significantly increases engagement, teaching opportunities and interest in the surgical procedure from all present in the OR.

The use of the endoscope enables the surgeon to visualize past the shaft of larger surgical instruments, such as drills and curettes, and allows better visualization of anatomical structures.

  • Endoscopy-Assisted Transmeatal Cochlear Implantation in Multiple Ear Deformities July 26, 2021
    To study congenitally deaf children with inner ear malformations that usually have comorbid anomalous facial nerves and middle ear deformities. To determine the feasibility of endoscopy-assisted transmeatal cochlear implantation with the purpose of reducing the risks of iatrogenic facial nerve injury. This report presents a unique technique in a pediatric case with multiple ear anomalies: […]

  • Comparison of MRI and CT in the Evaluation of Unilateral Maxillary Sinus Opacification July 26, 2021
    CONCLUSIONS: MRI is more specific than CT in characterising UMSO, with greater diagnostic certainty and reproducibility. The additive diagnostic value of MRI complements CT, potentially reducing diagnostic delays in some cases and the need for diagnostic endoscopic sinus surgery in others. We recommend MRI incorporation into the diagnostic pathway for patients with UMSO.

  • Two-handed endoscopic ear surgery: Feasibility for stapes surgery July 17, 2021
    CONCLUSIONS: Adoption of the two-handed technique during endoscopic stapes surgery ensures the surgeon benefits from the advantages of endoscopy while overcoming the disadvantages of the one-handed technique.

  • Effect of gamma-secretase inhibitor on middle ear ultrastructures in ovalbumin-mediated otitis media with effusion in rats July 14, 2021
    Objective: To study the effect of the inhibitor of Notch signaling pathway-γ-secretase inhibitor DAPT on the ultrastructures of middle ear in the ovalbumin (OVA)-mediated allergic OME in vivo. Methods: Male Sprague-Dawley (SD) rats, weighing 250-300 g, were completely and randomly divided into three groups (5 rats, 10 ears in each group):(1)Control group(2)OME group(3)OME+DAPT group. Rats […]

  • Nasal Maggot Infection in a Patient With Nasal Non-Hodgkin's Lymphoma July 8, 2021
    We describe a case of nasal non-Hodgkin's lymphoma in a 79-year-old Chinese patient accompany with nasal myiasis. The first 2 biopsies in this case were false negative. Subsequently, nasal maggots developed in this patient. After removing all maggots under nasal endoscopy, the patient continued to have recurrent fever and was transferred to a higher hospital […]

  • Stridor: a rare presentation of motor neuron disease July 7, 2021
    A 74-year-old farmer presented to the emergency department with a subacute history of progressive dyspnoea, wheeze and dysphonia. He was treated for an exacerbation of asthma with poor response to pharmacological therapy. Investigation of dysphonia via laryngoscopy identified a bilateral vocal cord palsy. Subsequently, the patient developed an episode of life-threatening stridor and hypercapnic respiratory […]

  • A 'chemical help' in middle-ear surgery? A systematic review on sodium 2-mercaptoethanesulfonate July 5, 2021
    CONCLUSION: Mesna application in cholesteatoma surgery could represent a valid and safe support tool during surgical treatment carried out both with microscopy and endoscopy. More studies are required to confirm these promising results.

  • Antibacterial Activity of a Fractionated Pistacia lentiscus Oil Against Pharyngeal and Ear Pathogens, Alone or in Combination With Antibiotics July 5, 2021
    Previous studies have clearly demonstrated that the addition of lentisk oil (LO) to streptococcal cultures makes it possible to differentiate Streptococcus spp. into three categories with Streptococcus mitis and Streptococcus intermedius sensitive, Streptococcus pyogenes, Streptococcus agalactiae, and Streptococcus mutans partially sensitive, and Streptococcus salivarius insensitive to the product. We have investigated here whether the winterization […]

  • Videofluoroscopic Swallow Study in Diagnostics of H-Type Tracheoesophageal Fistula in Children June 30, 2021
    Esophageal atresia remains one of the most challenging congenital anomalies of the newborn. It can occur with or without tracheoesophageal fistula (TEF), and to date, there are still no universally recommended diagnostic procedures. The so-called H-type TEF is that without esophageal atresia, and its prevalence is lower than 5% of all TEFs. We present a […]

  • Lacrimal sac rhinosporidiosis June 29, 2021
    Rhinosporidiosis is a chronic mucocutaneous granulomatous disease caused by Rhinosporidium seeberi, involving primarily the nose and nasopharynx. Very rarely, the disease can affect the lacrimal sac. Here we report a 35-year-old male patient who had rhinosporidial involvement of the nose 5 years ago, for which he underwent endoscopic nasal surgery. Five years after the excision […]
