A single centre's experience of 23 cases of total rhinectomy for the treatment of squamous cell carcinoma involving the nasal vestibule.

Abstract

This study aims to analyse the oncological outcomes of total rhinectomy (TR) for squamous cell carcinomas (SCCs) involving the nasal vestibule, and to identify prognostic factors for disease recurrence. A retrospective single-centre study was conducted between September 2003 and February 2021 including all patients who underwent a TR for a SCC involving the nasal vestibule. 23 patients were included in the study. Tumours originated from the anterior septum (n = 12), vestibule (n = 8) or skin (n = 3). Six TRs (26.1%) were salvage procedures, after primary radiotherapy or partial rhinectomy. Seven patients had a concurrent neck dissection and 17 patients (73.9%) received adjuvant treatment (14 patients had radiotherapy and 3 had chemoradiotherapy). After a median follow-up of 32months, six patients (26.1%) presented with tumour recurrence. Three patients (13%) had nodal-only recurrence. The estimated 5-year overall survival, disease-free survival and disease-specific survival were 67.5%, 66.3% and 80.7%, respectively. Positive excision margins were a predictive factor for tumour recurrence (p = 0.0401). For SCCs involving the nasal vestibule that are not amenable to limited surgical resection, TR along with adjuvant radiotherapy provide good oncological outcomes and should be considered the main treatment option.
