    Abstract The micro-ear instruments are designed to work with the operating oto-microscope where the principle of working depends on the magnification and the focal length of the objective lens. The focal length of the microscope allows a greater working distance for manipulation of the instruments. During the endoscopic ear surgery, the length of instrument interferes with the length of the endoscope making the working under the lens difficult. Hence reaching to the corners of the middle ear becomes impossible with the straight micro-ear instruments during endoscopic ear surgery. Hence certain modifications are required in the existing micro ear instruments so as to be used in endoscopic ear surgery.

    Abstract The micro-ear instruments are designed to work with the operating oto-microscope where the principle of working depends on the magnification and the focal length of the objective lens. During the endoscopic ear surgery, the length of instrument interferes with the length of the endoscope making the working under the lens difficult. Hence certain modifications are required in the existing micro ear instruments so as to be used in endoscopic ear surgery to reach the nooks and corners of the middle ear. In this manuscript, we describe the angle rendered to the flag knife.

    Abstract Endoscopes have revolutionised and have added a new dimension to the surgical domain. Many surgical techniques have reformed from the open surgical approach to a minimal access endoscopic one. In otolaryngology too, the indications and the use of endoscopes have been increasing in the last few decades. Even in otology, slowly and steadily Wulstein's microscopic techniques have been changing to endoscopic techniques. The only disadvantage of endoscopic ear surgery is that it is a single handed technique as the non dominant hand is utilised in holding the endoscope. We have developed portable endoscope holder based on the Goose neck system with rack and pinion mechanism. The goose neck system acts as a third arm to hold the endoscope. The novel portable endoscope holder bears the potential to provide benefits for various endoscopic ear nose and throat surgeries. We present our experience of feasibility and applicability of this endoscope holder.

    Abstract There are temporal bone dissection workshops organised all-over the world, however, there is no dedicated teaching program to train in slicing techniques for cartilage tympanoplasty. The aim of the study is to train the otologists in slicing techniques in cartilage tympanoplasty using sheep auricular cartilage as a teaching model and to evaluate the impact of the training on the participants. A total of 98 otologists have been trained in slicing techniques using cartilage slicer during 7 workshops organised at our centre from January 2016 to January 2020 for a total of 6 days for each trainee. Each trainee performed slicing techniques in cartilage tympanoplasty using 5 sheep pinna. Evaluation of the impact of the training was done in terms of assessment of improvement in performance. The feedback forms evaluated the training technique with sheep cartilage, its feasibility and usability as a model for teaching. The impact of the training on the overall performance of the trainee was assessed in terms of confidence, ability and speed in performing tasks related to slicing and cartilage tympanoplasty. The simulation in slicing techniques using sheep auricular cartilage has a teaching potential to improve the surgical outcomes of tympanoplasty as assessed by the performance of the participants. Level of evidence: 4.

    Abstract We report the technique of two handed transcanal endoscopic ossiculoplasty using tragal cartilage in the form of boomerang as an option for total ossicular replacement in absence of stapes superstructure. In this technique, the vertical strut is fashioned as a boomerang and measures 10 mm in length and 2 mm in breadth. A partial thickness cut is made on the vertical strut at 4-4.5 mm along the length so that it can be bent into boomerang, one end of which is placed on the stapes footplate and the other part rests in the hypotympanum. This stable assembly is placed on the footplate of the stapes (when all ossicles are absent). Tympanic membrane reconstruction is performed with or without attic reconstruction, using sliced tragal cartilage of 0.5 mm thickness. Boomerang ossiculoplasty is good option in cases of absent stapes providing a stable assembly. The use of endoscope holder during ear surgery gives additional advantages of panoramic view of middle ear spaces due to use of endoscope along with benefits of two handed technique (similar to microscopic ear surgery).

    Abstract In present world of contemporary techniques of microscopic ear surgery and single handed endoscopic ear surgery, we propose the technique of two handed endoscopic tympanoplasty using endoscope holders. The aim of the study  is to evaluate the functional and anatomical results of our technique of endoscopic type 3 cartilage tympanoplasty using endoscope holder. It is a Retrospective Non Randomized Clinical Study. A total of 67 endoscope holder assisted exclusively two handed endoscopic type 3 cartilage tympanoplasties performed from December 2014 to March 2017 with our technique were included in the study. Patients with pars tensa retractions and perforations with absent incus were included in the study. Those with cholesteatoma were excluded from the study. Full thickness tragal cartilage disc of 3 × 3 mm dimensions with a circular slot of 1 mm to fit onto the head of the stapes was used for reconstruction. Tympanic membrane reconstruction was done along with attic reconstruction, using sliced tragal cartilage of 0.5 mm thickness. Patients were assessed at 6, 12 and 24 months for graft status. In early follow up period ranging from 24 to 52 months, the graft take up was seen in 64 ears with three perforations giving a success rate of 95.52%. The pre-operative air-bone gap was 42.6 ± 3.26 dB and the post-operative air-bone gap at 6 months, 1 and 2 years was 18.36 ± 3.46 dB, 19.42 ± 4.32 dB and 19.53 ± 4.33 dB respectively. The study reports good air-bone closure to 20 dB postoperatively following type 3 endoscopic tympanoplasty using endoscope holder. Slotted cartilage graft is definitely an excellent option for ossiculoplasty in cases of absent incus providing a stable assembly. Level of evidence: Level 4.

    Abstract The pandemic of COVID 19 has taken a massive toll of lives since its outbreak. Throughout the world with a large number of people being affected by covid 19, the need for the ventilators has risen. However, there is disproportionate ratio of demand versus supply of ventilators due to the menace caused by Covid 19 which has become unmanageable. This paper describes the design of the low cost portable mechanical bag valve mask compressor which could serve as a preliminary ventilator for the patients needing ventilator support in COVID 19. This prototype ventilator delivers breaths by compressing a conventional bag-valve mask (BVM) with a motor, eliminating the need for a human operator for the BVM. It is driven by a wind shield wiper electric motor powered by a 12 V battery. Additionally it can be used to deliver oxygen through either Laryngeal mask or compact face masks or nasopharyngeal airways where intubation is awaited in early breathlessness. Future additions for our prototype ventilator will include a controllable inspiration to expiration time ratio, a pressure relief valve, PEEP capabilities and an LCD screen. With a prototyping cost of only $150, the concept of BVM compressor is a low-cost, low-power portable ventilator technology that will provide essential ventilator features at a fraction of the cost of existing technology.

    Abstract Objectives: STUDY DESIGN: Observational study.
    Setting: Secondary care ENT Centre.
    Methods: All patients attending the hospital for office ENT consultations from 15th April 2020 to 15th September 2020 were included in the study. A total of 6692 office patients were evaluated for feasibility, usability and tolerability of the 0.5% PVP-I gargles and nasal drops.
    Results: Overall practicability of using 0.5% PVP-I gargles and nasal drops at office level was assessed in terms of feasibility and usability. Feasibility and usability was considered in terms of the ease of the dispensing method of the 0.5% PVP-I gargles and nasal drops by the health care workers to the patients prior to ENT examination. Tolerance was assessed in terms of altered taste, staining of teeth or nasal skin or irritation in the nose. None reported any serious reactions or adverse effects following use of 0.5% PVP-I.
    Conclusion: The study reports the successful feasibility and usability of 0.5% PVP-I gargles and nasal drops and bears the potential to provide benefits in preventing transmission from the patients to the health care workers and vice versa.
