“…Otalgia and typical TMJ syndrome symptoms were not a feature in these patients. The most common cause of mass within with EAC is exostosis and osteomas [ 5 ]. In patients where the appearance of the EAC lesion is atypical, imaging is often indicated.…”

Temporomandibular joint (TMJ) ganglionic cyst is an uncommon entity and only a few have been reported in the literature. TMJ ganglion within the external auditory canal presenting clinically as a fluctuating cystic lesion has never been reported. Here, we present a unique case of such a lesion together with otoscopic and radiological images as well as provide a descriptive review of TMJ ganglionic cysts.

“…Extraneural cysts in this location can be asymptomatic or symptomatic (causing neural symptoms due to extrinsic nerve compression 3,4,8,23,33 or mastication difficulties because of the mass 2,7,20,32 ). They are derived from the TMJ via non-neural pedicles and can extend in different directions, even intraosseously 2,8,16,26 or intracranially 18,23,33 (Fig. 3B).…”

abbreviatioNs MIP = maximum intensity projection; TMJ = temporomandibular joint. submitted April 9, 2014. accepted December 10, 2014. iNclude wheN citiNg Published online February 6, 2015; DOI: 10.3171/2014.12.JNS14798. disclosure The authors report no conflict of interest concerning the materials or methods used in this study or the findings specified in this paper. The authors describe the case of an intraneural ganglion cyst involving a cranial nerve (V3), which was found to have a joint connection in support of an articular origin within the cranial nerves. An inferior alveolar intraneural cyst was incidentally discovered on a plain radiograph prior to edentulation. It was resected from within the mandibular canal with no joint connection perceived at surgery. Histologically, the cyst was confirmed to be an intraneural ganglion cyst. Reinterpretation of the preoperative CT scan showed the cyst arising from the temporomandibular joint. This case is consistent with the articular (synovial) theory of intraneural ganglion cysts. An anatomical explanation and potential joint connection are provided for this case as well as several other cases of intraneural cysts in the literature, and thus unifying cranial nerve involvement with accepted concepts of intraneural ganglion cyst formation and propagation.

“…Although ganglion cysts are the most common benign tumors of the wrist and hand, those associated with the temporomandibular joint (TMJ) are very rare. 1 To the best of our knowledge, this is the only second report of a ganglion cyst originally presenting as an external auditory canal (EAC) mass without any definite anterior canal wall defect.…”

“…The most common EAC masses are benign tumors, including exostoses and osteomas. 1 These are generally considered to be asymptomatic masses. They are different from ganglion cysts, which have a slowly growing cystic component that can induce aural fullness and hearing loss, as in our patient.…”

“…Canalplasty with skin grafting and wide meatoplasty were also performed via a preauricular/ endaural approach through a second-stage operation. 1 However, we excised the mass and soft tissue connected to the TMJ by canalplasty via a retroauricular/ endaural approach and reconstructed the defect of the anterior bony EAC with conchal cartilage and temporalis fascia. We propose that this technique has advantages both in the graft materials used and the surgical view.…”
