BackgroundTransoral robotic surgery (TORS) represents a novel treatment for oropharyngeal cancer and obstructive sleep apnea. Appropriate patient selection is crucial. The purpose of this study was to investigate whether anatomic biometric measures are useful to determine the feasibility of performing TORS.
MethodsThree surgeons independently evaluated feasibility in 51 soft-fix cadavers. Transoral visualization was performed with 2 retractors commonly used in TORS. Seven anthropometric parameters and the degree of mouth opening were recorded.
ResultsMandibular body height, hyoid-mental length, and neck circumference demonstrated significant differences between suboptimal and adequate visualization of base of tongue and epiglottis (p < .05). Limited mouth opening was associated with suboptimal visualization. Neck circumference had the strongest influence on predicting TORS feasibility.
ConclusionMandibular body height, hyoid-mental length, and neck circumference in conjunction with the degree of mouth opening may determine patient suitability for TORS. Clinical evaluation is essential to validate their collective usefulness.
