ABSTRACT
Posterior pharyngeal wall squamous cell carcinomas (SCCs) are rare and have an associated poor prognosis. Progress in transoral resection techniques, in particular, transoral robotic surgery (TORS), have renewed the role of surgery in their treatment. This article presents the oncological and functional results obtained by the French Group of Head and Neck Robotic Surgery for TORS for posterior pharyngeal wall SCC-curative surgery. This retrospective, multicentre study presents data collected between September 2009 and November 2013 for patients treated with TORS for posterior pharyngeal wall SCCs. Analysis of patient characteristics, tumour and treatment details were completed. Kaplan-Meier analysis was used to calculate overall survival rates and recurrence-free survival rates. Student's t test and Chi2 test were also calculated. 23 patients were included (mean age of 62 years). 12 patients had a prior HNSCC. Ten patients had pT1 cancers. The overall two-year survival rate was 59%, but 89% for pT1 compared to 28% for pT2-T3 (p = 0.01). It was noted that TORS was simple to perform, but generated significant post-operative dysphagia. Two cases of spondylodiscitis were reported as specific post-operative complications of TORS. In conclusion, TORS is a treatment solution for selected posterior pharyngeal wall SCCs. It provides a possible alternative to medical treatment for early pT1 lesions and is often the only remaining curative solution in patients previously treated with radiotherapy. In cases of bulky resection, or when there is a past medical history of radiotherapy, a tissue reconstruction by forearm free-flap may be indicated.

Diplopia is a common presenting complaint with a broad spectrum of differential diagnoses. Causative pathologies may affect the eye, extraocular muscles, neuromuscular junction, cranial nerves and central nervous system. Tumours, inflammatory and autoimmune conditions, vasculopathies and atypical infections are the most common underlying pathologies. Solitary extramedullary plasmacytoma is a rare cause of diplopia. This case emphasises the importance of submucosal biopsies for diagnosis and early involvement of the multidisciplinary team. Moreover, we advocate a low threshold for a second opinion and further immunohistochemistry, particularly when there is diagnostic uncertainty with histological discordance.

INTRODUCTION: Necrotising otitis externa (NOE) is a severe infection of the temporal bone. The traditional severity based staging system does not fully prognosticate all patients with NOE. We hypothesise that a patient response staging system would more accurately capture the disease process and guide prognosis. METHODS: We carried out a retrospective notes review of patients diagnosed with NOE from January 2017 to December 2018 in a regional tertiary referral centre. Patient outcomes from our proposed patient response staging system were compared to a modified previously published severity based Gleeson staging system with patients requiring prolonged treatment classified as having a poor outcome. RESULTS: A total of 34 patients were treated for NOE. The majority were male (n=24) and had diabetes (n=25). Patients with the most severe Gleeson staging did not have the worst outcome. Daily delay in resolution of otorrhoea was associated with an increased need for more than six weeks of treatment. Rapid responders are patients who had resolution of otalgia, otorrhoea and C-reactive protein normalisation within 14 days, and all were cured following standard 6 weeks of treatment. CONCLUSIONS: The Gleeson staging system was valuable in assessing the extent of disease and all early Gleeson staged patients had good outcomes. However, patients with higher severity staging on the Gleeson system did not necessarily require prolonged treatment. There is a role for a joint approach in staging patients based on both modified Gleeson and treatment response, which would subsequently guide prognosis, duration of treatment and early diagnosis of potential fungal NOE.
