Comparison of Modified Mallampati Classification With M-TAC in Difficult Airway

Plain-language summary
The study title "Clinical trial of comparative evaluation of the Modified Mallampati Score and Modified Mallampati Score along with Thyromental distance, Anatomical abnormality, and Cervical mobility (M-TAC) in Predicting Difficult Airway " was undertaken to evaluate prediction of difficult airway by comparing preoperative airway evaluation tests.
Mallampati classification is the most used screening test for detection of difficult intubation it is a classification of oropharyngeal view. Other tests include sternomental distance, thyromental distance, Wilson risk sum score, upper lip bite test, protrusion of mandible, tooth morphology, head extension, mouth opening, body mass index, 3-3-2 rule and ultrasonography of neck soft tissue. We studied 200 adult ASA I \& II patients of either sex, aged between 18-60 yrs undergoing elective surgery receiving general anesthesia.
Modified mallampati classification had four grades \& each grade was given a score, similarly thyromental distance (TMD), anatomical abnormality (AA) \& cervical mobility (CM) was classified into three grades \& each grade was given a score. For M-TAC individual scores were added.

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
