Pre-operative CT cephalometry and functional outcomes after open partial horizontal laryngectomy

Area of Science:

• Otolaryngology
• Radiology
• Oncology

Background:

• Open partial horizontal laryngectomy (OPHL) is a surgical procedure for laryngeal cancer.
• Predicting functional outcomes after OPHL is crucial for patient management.
• Pre-operative assessment aids in optimizing surgical planning and patient expectations.

Purpose of the Study:

• To identify pre-operative radiological parameters predicting functional outcomes after OPHL.
• To establish correlations between airway dimensions and post-operative results.
• To enhance the prognostic value of radiological staging in laryngeal cancer surgery.

Main Methods:

• Retrospective study of 96 patients with laryngeal squamous cell carcinoma.
• Pre-operative contrast-enhanced computed tomography (CT) of the neck.
• Univariate and multivariate analyses of demographic, surgical, and cephalometric variables.

Main Results:

• Larger anteroposterior airway dimensions in the mid-retroglossal area predicted better decannulation rates.
• Greater distance between the genial tubercle and hyoid bone correlated with improved functional outcomes.
• Pre-operative upper aero-digestive tract diameters and volumes were significant predictors.

Conclusions:

• Pre-operative radiological parameters, specifically upper airway dimensions, are valuable predictors of functional outcomes post-OPHL.
• Enhanced radiological assessment can guide surgical decisions and improve patient prognoses.
• Larger airway measurements are associated with superior post-operative functional recovery.
