Nasopharyngectomy with operating microscope: A case series.

BACKGROUND: Nasopharyngectomy for excision of nasopharyngeal tumors is challenging, as access to the nasopharynx is difficult. Recently our institution embarked on two new approaches - robotic nasopharyngectomy and open nasopharyngectomy with operating microscope (NOM) via maxillary swing approach. This article proposes that the novel approach of NOM via maxillary swing aids visualization for resection of locally invasive nasopharyngeal tumors. METHODS: Over a thirteen-month period, eight patients required nasopharyngectomy in our single Asian institution. Four underwent robotic nasopharyngectomy and four underwent NOM via maxillary swing approach. The latter four were retrospectively reviewed, and their clinical characteristics and surgical outcomes reported. Tips and pearls for operative setup and patient selection were also discussed. RESULTS: All four patients who underwent NOM had negative intraoperative frozen sections with subsequent negative paraffin sections. All patients remained disease free post-salvage surgery. CONCLUSION: NOM via maxillary swing allows better visualization and aids in augmentation of open nasopharyngectomy. This enables achievement of adequate resection margins and fewer surgical complications in locally invasive nasopharyngeal tumors.
