Predictive variables for difficult intubations in oral and maxillofacial surgery

Area of Science:

• Anesthesiology
• Otolaryngology
• Oncology

Background:

• Endotracheal intubation difficulty is influenced by patient factors.
• Existing assessment tools for intubation difficulty are often inadequate.
• Orofacial tumors present unique challenges for airway management.

Purpose of the Study:

• To evaluate the predictive value of LEMON score, demographic indices, tumor site, and intraoral tumor position for intubation difficulty.
• To identify key variables for assessing airway management in patients with orofacial tumors.

Main Methods:

• Retrospective analysis of patients with orofacial tumors undergoing intubation.
• Assessment of LEMON score, demographic data, tumor site, and intraoral position.
• Statistical correlation between predictive variables and actual intubation difficulty.

Main Results:

• A significant correlation was found between LEMON score predictions and actual intubation difficulty.
• Neck mobility and Mallampati scores were significant criteria within the LEMON score.
• Optimal Interincisal Distance (OID) showed a significant association with intubation difficulty.
• Tumor site and intraoral position did not significantly impact intubation difficulty.

Conclusions:

• The LEMON score is a valuable tool for predicting intubation difficulty in orofacial tumor patients.
• Demographic indices, particularly OID, should be considered in airway assessment.
• Neck mobility, Mallampati score, and OID warrant greater emphasis in pre-intubation evaluations.
