Introduction: Non-arteritic ischaemic optic neuritis is a known post-operative complication of ophthalmological and maxillofacial surgery, but has not been widely described as a potential consequence of head and neck surgery.
Aim: To highlight non-arteritic ischaemic optic neuritis as a potential risk in patients undergoing head and neck surgery.
Subject And Method: Case report of a 60-year-old man undergoing total laryngectomy and bilateral neck dissection for laryngeal squamous cell carcinoma.
Result: On day 14 post-operatively, the patient suffered substantial oral bleeding secondary to an internal jugulo-neopharyngeal fistula. Following emergency haemostatic measures, the patient was immediately aware of visual disturbances. The ophthalmologists concluded that these were due to non-arteritic ischaemic optic neuritis, caused by acute hypoxaemia secondary to substantial blood loss.
Conclusion: The prognosis of non-arteritic ischaemic optic neuritis is poor. Thus, it is crucial that otolaryngologists are aware of this complication of head and neck surgery, as immediate diagnosis and treatment can help prevent worsening visual loss.

Background: Both anxiety and depression are prevalent among patients with chronic rhinosinusitis (CRS) and associated with poorer outcomes following treatment for CRS. However, the impact of treatment on CRS on mental health remains uncertain. Therefore, this study seeks to evaluate if surgical intervention for CRS may alleviate comorbid depression and anxiety.

Background: Olfactory neuroblastoma (ONB) is a rare sinonasal malignancy primarily treated with surgery. For tumors arising from the olfactory area, traditional treatment involves transcribriform resection of the anterior cranial fossa. Surgery can be performed with unilateral or bilateral resection depending on extent of involvement; however, there are currently no studies comparing outcomes between the two.
