Although patient-specific three-dimensional (3D) reconstruction improves anatomical visualisation, standardised methods for incorporating this information into surgical approach selection remain poorly defined. We developed the Vall d’Hebron 3D-PPS Workflow and Algorithm to integrate patient-specific anatomy into preoperative decision-making.</p>Methods<p>Prospective observational study including 17 consecutive patients with PPS lesions treated at a tertiary referral centre.

All patients underwent patient-specific 3D virtual planning integrating CT and MRI datasets. The primary outcome was the impact of the Vall d’Hebron 3D-PPS Workflow on surgical approach selection. Secondary outcomes included postoperative complications, surgical margins or completeness of lesion resection, length of hospital stay and surgeon-reported usefulness of the 3D models.</p>Results<p>Surgical treatment consisted of transoral robotic surgery (TORS) in seven patients (41.2%), transcervical surgery in four (23.5%), combined external plus TORS in four (23.5%) and transcervical–transparotid surgery in two (11.8%).
