Rhabdomyosarcoma is a rare malignant tumour of striated muscle accounting for 3% of all primary soft tissue tumours of the middle ear cavity. We describe a unique case of a rhabdomyosarcoma of the middle ear cavity in a four-year-old boy, presenting as an otherwise asymptomatic ipsilateral Horner’s syndrome. This case involved tumour erosion through the tensor tympani semicanal, accessing the carotid canal and the sympathetic plexus running through it. This child was treated successfully with chemotherapy and proton beam therapy, and remains disease free at six years of follow-up. This case highlights the importance of investigating patients with non-resolving ear infections, polyps or granulation tissue.

AbstractBackground:Functional endoscopic sinus surgery is recognised to have a significant complication profile (e.g. blindness, cerebrospinal fluid leak and intracranial sepsis). Pre-operative computed tomography imaging is considered mandatory for surgical planning to reduce intra-operative risk. A radiological report is the ‘gold standard’ in image interpretation; however, because of a lack of otolaryngological or radiological guidance, its contents may be variable. By surveying practising otolaryngologists, this study aimed to provide some guidance which may be used by radiologists to produce more surgically relevant radiological reports.Method:A prospective questionnaire was distributed to the ENT-UK panel.Results:A total of 117 consultant members of the panel completed the survey. Twenty-nine per cent indicated that they were uncomfortable interpreting all areas of the computed tomography scan. Greatest importance was given to areas including the ethmoid roof (dehiscence, asymmetry and angle), lamina papyracea (dehiscence) and sphenoid sinus (carotid canal dehiscence and optic nerve relationships).Conclusion:Functional endoscopic sinus surgery is commonly performed by non-subspecialist rhinologists. The information obtained from this study can be used by radiologists to improve report relevance, particularly for the generalist ENT surgeon. This contributes to improving patient safety and helps avoid medicolegal litigation when complications arise.

Canal Dehiscence

Dehiscence of bone overlying the superior semicircular canal can result in a syndrome of vertigo and oscillopsia induced by loud noises or by maneuvers that change middle ear or intracranial pressure. Patients with this disorder can also experience a heightened sensitivity to bone-conducted sounds in the presence of normal middle ear function. High-resolution CT scans of the temporal bones demonstrate the dehiscence. The authors describe a patient with bilateral superior canal dehiscence who had bilateral low-frequency conductive hearing loss, normal middle ear function, intact acoustic reflexes, and intact vestibular-evoked myogenic potentials. These findings would not be expected on the basis of a middle ear cause of the conductive hearing loss. A high-resolution CT scan of the temporal bones in this patient revealed bilateral superior canal dehiscence. Normal acoustic immittance findings in the presence of conductive hearing loss should alert clinicians to the possibility of inner ear cause of an air-bone gap due to superior canal dehiscence

Schwannomas in the middle ear and external auditory canal are exceedingly rare. The facial nerve, chorda tympani nerve, and Jacobson’s nerve have rarely been reported as the origins of primary schwannomas in the middle ear cavity. We experienced a case of carotid sympathetic plexus (CSP) schwannoma that arose from the carotid canal and extended into the middle ear and external auditory canal. The tumor presented bone erosion of the carotid canal, and it adhered tightly to the internal carotid artery. This report represents the first documented case of a CSP schwannoma, which involved the middle ear and external auditory canal.
