Orbital complications after endoscopic sinus surgery (ESS), such as optic nerve or medial rectus injuries, are well known, but isolated complete oculomotor nerve palsy has never been reported. In this case, a 31-year-old male was transferred to our hospital after ESS. Physical examination showed complete left oculomotor nerve palsy, with a bony defect on the sellar floor, which had not fully recovered after more than 1 year. We hypothesized that blunt trauma could be the main cause of the oculomotor palsy. Surgeons performing ESS must keep in mind the possibility of oculomotor palsy due to blunt trauma, especially when operating around the sphenoid and posterior ethmoid sinus.

Neurilemmoma of the head and neck is not rare in parapharynx, but rare in the larynx. The treatment of choice in neurilemmoma of the larynx is a complete surgical resection. A small size lesion can be removed via an endoscopic approach. For a large size lesion, an external approach, such as the median or lateral thyrotomy, or pharyngotomy, can be more useful. These surgical methods often require preliminary tracheostomy to secure the airway. Through a case of neurilemmoma of the larynx, we present this disease and the treatment course of a patient, who has been successfully treated by surgical excision via trans-cricothyroid membrane approach without tracheostomy. Furthermore, we discuss its symptoms, physical examinations, microscopic features and other options of treatment for laryngeal schwannoma through literature reviews.
