A Step towards Achieving Sustainable Otologic Surgery in Low-Resource Settings: A Cost Comparison between Shipping an Otologic versus Microscopic Surgical Setup.

Background: The advancement of otologic surgery in low-resource settings has been limited by the cost and transport of surgical equipment. This study compared the transportation costs of an otologic microscopic surgical setup (MSS) versus an endoscopic surgical setup (ESS) in low- and low to middle-income countries (LMICs) for surgical teaching. Methods: Dimensions of microscopes, endoscopes and associated surgical instruments were used to calculate shipping costs from Minneapolis, MN, USA to Kenya, Haiti and Sri Lanka. Results: The average cost of internationally shipping the ESS is less than the MSS in Kenya (ESS: USD 1344.03; MSS: USD 20,947.00; p = 0.370), Haiti (ESS: USD 549.11; MSS: USD 1679.00; p < 0.05) and Sri Lanka (ESS: USD 945.38; MSS: USD 8490.57; p = 0.377). Freight shipping was required for the MSS while the ESS can be packed into an international checked bag for USD 35.00 USD. Discussion: The ESS has fewer logistical barriers than the MSS, making the endoscope a feasible option for surgical teaching in LMICs.

Elective otological healthcare under COVID-19 contaminations risks

The COVID-19 pandemic has raised unprecedented challenges for all types of medical personnel and health care workers. The avidity of the novel coronavirus for oropharynx and nasopharynx renders otolaryngologists at particular risk of infection. Therefore, the resumption of elective otological care requires personal protective equipment (PPE), thorough (pre)screening and irrefutable hand hygiene. A literature search was conducted on May 5th, 2020. All recommendations concerning otological ENT (Ear Nose Throat), both during outpatient consultation and in the operating theatre, were scored for abundance. Highly recurrent advice was using PPE during each patient encounter, social distancing in the waiting room and teleconsultation before each consultation. Concerning audiological testing, most articles advised social distancing during testing and remote hearing screeners. For resumption of elective otological surgery, preoperative screening, adequate PPE, and minimal staffing to reduce the contamination risk were most frequently advised. Awaiting an effective vaccination for the novel coronavirus, all elective otological health care requires critical appraisal of each case to assess the infectious risks for both patient and health care personnel.

Heads-up Surgery: Endoscopes and Exoscopes for Otology and Neurotology in the Era of the COVID-19 Pandemic.

A new era of surgical visualization and magnification is poised to disrupt the field of otology and neurotology. The once revolutionary benefits of the binocular microscope now are shared with rigid endoscopes and exoscopes. These 2 modalities are complementary. The endoscope improves visualization of the hidden recesses through the external auditory canal or canal-up mastoidectomy. The exoscope provides an immersive visual experience and superior ergonomics compared with binocular microscopy. Endoscopes and exoscopes are poised to disrupt the standard of care for surgical visualization and magnification in otology and neurotology.

Covid-19 and Ear Surgery: Treatment Strategies and Triage during the Post-lockdown Period.

The accumulated disease burden during lockdown period, due to postponement of regular surgeries, is expected to put additional pressure on surgeons during the post-lockdown period. Due to the contagious nature of SARS-CoV-2 and its suspected presence in middle ear mucosa and mastoid, Ear surgeons are bound to face a challenging situation in present times as well as in times to come. Through this article we aim to streamline fresh management strategies particularly for the post-lockdown period keeping in mind that immunity after vaccination may take a few months to develop due to various factors discussed in the article. The ENT Cochrane, Pubmed and Web of Science databases were searched extensively using the terms 'Covid-19 and SARS-CoV-2 in conjunction with Ear surgery and Otology. Data collected from these, put together with our experience helped us in putting forward fresh management strategies to deal with the current situation being experienced worldwide. To reduce the risk of infection to the healthcare staff, we have suggested a new triage strategy for ear surgeries to reduce the accumulated disease burden in the post-lockdown period until immunity by vaccination develops amongst a good number of Ear surgeons. Also we have put forward certain operating guidelines that might prove helpful for the Ear surgeon during these times. Fresh Triage guidelines mentioned in this article are particularly meant to help ear surgeons reduce the accumulated disease burden in the post lockdown-period with ease and efficacy. Since ear surgery poses a risk of infection to the healthcare workers, specific guidelines pertaining to ear surgery during the pandemic are mentioned in detail which in our opinion can be of immense help to all the healthcare professionals involved in ear procedures till the time the vaccine is administered on a large scale.

Quantification and Comparison of Droplet Formation During Endoscopic and Microscopic Ear Surgery: A Cadaveric Model.

OBJECTIVES: The COVID-19 pandemic and the disproportional spread of the disease among otorhinolaryngologists raised concerns regarding the safety of health care staff. Therefore, a quantitative risk assessment for otologic surgery would be desirable. This study aims to quantitatively compare the risk of perioperative droplet formation between microscopic and endoscopic approaches. STUDY DESIGN: Experimental research. SETTING: Temporal bone laboratory. METHODS: The middle ear of whole head specimens was injected with fluorescein (0.2 mg/10 mL) before endoscopic and microscopic epitympanectomy and mastoidectomy. Fluorescent droplet deposition on the surgical table was recorded under ultraviolet light, quantified, and compared among the interventions. Drilling time, droplet proportion, fluorescein intensity, and droplet size were assessed for every procedure. RESULTS: A total of 12 procedures were performed: 4 endoscopic epitympanectomies, 4 microscopic epitympanectomies, and 4 mastoidectomies. The mean (SD) proportion of fluorescein droplets was 0.14‰ (0.10‰) for endoscopic epitympanectomy and 0.64‰ (0.31‰) for microscopic epitympanectomy. During mastoidectomy, the deposition of droplets was 8.77‰ (6.71‰). Statistical comparison based on a mixed effects model revealed a significant increase (0.50‰) in droplet deposition during microscopic epitympanectomy as compared with endoscopic epitympanectomy (95% CI, 0.16‰ to 0.84‰). CONCLUSIONS: There is considerable droplet generation during otologic surgery, and this represents a risk for the spread of airborne infectious diseases. The endoscopic technique offers the lowest risk of droplet formation as compared with microscopic approaches, with a significant 4.5-fold reduction of droplets between endoscopic and microscopic epitympanectomy and a 62-fold reduction between endoscopic epitympanectomy and cortical mastoidectomy.
