Abstract

The advent of transoral robotic surgery (TORS) has allowed transoral approaches for parapharyngeal space (PPS) tumours to be re-evaluated. It provides enhanced visualisation and instrument access for appropriate tumours. We describe a specific technique, TORS narrow-field oropharyngectomy, that is ideal for benign PPS tumours which have been violated by intra-oral biopsy or incision and drainage. This allows the contaminated, overlying oropharyngeal mucosa to be resected en-bloc with the PPS tumour, reducing the risk of local recurrence. This technique provides a window into the PPS, improving visualisation of underlying neurovascular structures as well as the tumour. This reduces the risk of tumour spillage and leads to superior vascular access and haemorrhage control. This technique is only applicable to PPS tumours that are appropriate for transoral approaches and is specifically designed for those selected patients that have been placed at risk of seeding or local scarring by intra-oral procedures prior to definitive resection. We present two such cases: a 38-year-old male with a PPS inflammatory cyst, and a 66-year-old female with a PSS pre-styloid Schwannoma. This article is protected by copyright. All rights reserved.
