Manuscript Title: The Maxillary Swing Approach - The First Scandinavian Experience

BackgroundThe maxillary swing approach was introduced three decades ago in the head and neck field providing optimal surgical exposure for tumors in the nasopharyngeal and/or the retromaxillary space.ObjectivesTo report the clinical experience, patient surgical morbidity and survival outcomes following the introduction of the maxillary swing approach in Denmark.Material and methodsA retrospective study including patients who underwent the maxillary swing approach from January 2012 - January 2020. Baseline and perioperative data, pathology, postoperative morbidity and survival outcomes were registered.ResultsSixteen patients were included of which 15 had a malignant tumor with different histology, while one patient had a benign tumor. Most commonly reported short-term morbidity were trismus, cheek hypoesthesia, nasopalatal fistula, lacrimation and nasal stenosis (<3 months postoperatively) improving markedly at 12 months follow-up. For patients with malignant tumors, the 5-year overall survival and recurrence-free survival rates were 60% and 66.7%, respectively.Conclusions and significanceThe maxillary swing approach was safely implemented by a multidisciplinary team at a high-volume centralized head and neck cancer center in Denmark. The procedure may be considered for salvage surgery of recurrent nasopharyngeal carcinomas and selected malignant and benign tumors located in the nasopharynx and/or retromaxillary space inaccessible by other surgical modalities.
