Objective
To develop a simulator of the external auditory canal and tympanic membrane that enables surgical trainees to practise their otomicroscopy skills, which is particularly valuable at a time where there is limited patient contact because of the coronavirus disease 2019 lockdown.
Methods
A simulator of the external auditory canal and tympanic membrane was made using a cardboard bowl, a 2 ml syringe and a latex glove. The simulator was used to practise otomicroscopy skills, including microsuction, foreign body removal, myringotomy and grommet insertion. Five doctors in the ENT department participated, ranging from core surgical training year two doctor to specialty doctor.
Results
The simulator provides an effective tool on which surgical trainees can practise, develop and maintain a variety of otomicroscopy skills.
Conclusion
This inexpensive, easy and quick-to-make simulator enables trainees to practise their otomicroscopy skills on an approximately accurate model during a time when there is minimal clinical opportunity to develop these skills, particularly because of the coronavirus disease 2019 pandemic.
SummaryTwo patients who had undergone emergency tracheal intubation developed signs of aspiration of ingested food. Nasendoscopy demonstrated supraglottic anaesthesia which recovered from the laryngeal margins in towards the vocal cords. It is assumed that this was caused by a neuropraxia of the internal branch of the superior laryngeal nerve, presumably as a result of trauma related to intubation.
Defects in the tegmen tympani can have serious consequences such as intracranial infection and seizures, however, they can be difficult to diagnose due to their subtlety on cross-sectional imaging and the non-specific way in which they can present. Repair of such defects can be undertaken via a middle fossa or transmastoid approach; both, however, usually necessitate a general anaesthetic and, furthermore, middle cranial fossa surgery carries the risk of epilepsy while transmastoid repair can result in the loss of hearing. We present a novel method of repair in a patient who would otherwise have been managed conservatively.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
