The authors discuss the utility of anterior transposition of the oculomotor nerve from the lateral wall of the cavernous sinus to widen the corridor posterior to the cisternal segment of the oculomotor nerve; this allows exposure of the anterolateral surface of the midbrain. This additional exposure was successfully used for the resection of a large calcified cavernoma in the upper brainstem of a 67-year-old woman who had presented with sudden onset of left hemiparesis and oculomotor palsy. The patient's postoperative course was uneventful and she displayed symptomatic improvement.

Botulinum neurotoxin type-A (BoNT/A), which blocks quantal acetylcholine (ACh) release at the neuromuscular junction (NMJ), has demonstrated its efficacy in the symptomatic treatment of blepharospasm. In 3.89% of patients treated for blepharospasm at Tenon Hospital, BoNT/A was no longer effective in relieving the patient's symptoms, and a partial upper myectomy of the muscle was performed.

The authors present a case of an orbital apex venous malformation that presented with an intermittent oculomotor nerve palsy over a 15-year period. Radiologically, the lesion presented as a well-circumscribed orbital mass with T2 hyperintensity and enhancement that could only be demonstrated on 2-hour delayed phase imaging. The venous malformation was initially steroid-responsive but eventually became refractory to medical treatment alone.

Recent advancements in endovascular treatment (EVT) and different views on optimal management for posterior communicating artery (PComA) aneurysms with oculomotor nerve palsy (ONP) highlight a need to compare recovery timelines between microsurgery and EVT; heterogeneous outcomes and influencing factors may also affect results. A comprehensive systematic review and meta-analysis were conducted by searching PubMed, Embase, Scopus, and Web of Science databases. The extracted data encompassed patient demographics, details on treatment modalities and timing, and characteristics of PComA aneurysms ONP caused by either unruptured or ruptured aneurysms.

Purpose: To report a treatment approach of a rare presentation of herpes zoster ophthalmicus (HZO) with optic neuropathy and oculomotor nerve palsy.
Methods: Report of one case.
Results: Multiple lesions involving the optic nerve and cavernous sinus were demonstrated on magnetic resonance imaging in a patient with a characteristic herpes zoster rash in the V1 dermatomal distribution.
