An observational study in Neck Disease, Trismus and Tooth Abnormalities, sponsored by Keimyung University Dongsan Medical Center. Completed at 1 site in Korea, Republic of. Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2018-12-21.

If the patients's teeth are weak or the mouth dose not open well, the lightwand is a useful device when endotracheal intubation is necessary.
Therefore, if the appropriate position of the light beam is determined and the distance of the light source suitable for intubation using the lightwand is obtained from anatomical structures such as thyroid cartilage and cricoid cartilage, it is clinically useful. Because it can prevent unnecessary deep insertion or shallow insertion that can cause damage to anatomical structures during intubation.
Studies have been reported on the proper position to bend the lightwand and the appropriate angle to bend when performing endotracheal intubation with lightwand. For ease of procedure, the assistant has to lift the patient's lower jaw or perform a neck extension.
However, there is no report on the position of the lightbulb when the light passes through the front of the airway and neck and appears bright in the midpoint.
The prodcedure is as follows.
107 studies on the registry are indexed under Trismus; 19 are open to participants now.

This is an adult patient who is 18 years of age or older who undergoes general anesthesia requiring intubation.
Among them, patients who are unable to extend their necks, have trismus or have weak teeth are selected.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
