The temporomandibular joint: pneumatic temporal cells open into the articular and extradural spaces

The pneumatisation of the articular tubercle (PAT) of the temporal squama is a rare condition that modifies the barrier between the temporomandibular joint (TMJ) space and the middle cranial fossa. During a routine examination of the cone-beam computed tomography (CBCT) files of patients who were scanned for dental medical purposes, we identified a case with multiple rare anatomic variations. First, the petrous apex was bilaterally pneumatised. Moreover, bilateral and multilocular PAT were observed, while on one side it was further found that the pneumatic cells were equally dehiscent towards the extradural space and the superior joint space. To the best of our knowledge, such dehiscence has not previously been reported. The two temporomastoid pneumatisations were extended with occipital pneumatisations of the lateral masses and occipital condyles, the latter being an extremely rare evidence. The internal dehiscence of the mandibular canal in the right ramus of the mandible was also noted. Additionally, double mental foramen and impacted third molars were found on the left side. Such multilocular PAT represents a low-resistance pathway for the bidirectional spread of fluids through the roof of the TMJ. Further, it could add to a morphological picture of hyperpneumatisation of the posterior cranial fossa floor, which could signify the involvement of the last four cranial nerves in the clinical picture of TMJ pain.

“…During routine oral and maxillofacial radiology practice, portions of the base of the skull that include the temporal bone are visualised [13]. It is hence important for dentists and oral radiologists alike to be aware of common anatomical variations and pneumatisation patterns [13].…”

“…It is known that the advances in CBCT for use in general dentistry and oral and maxillofacial radiology over the past decade have led to a variety of maxillofacial applications, including evaluation of portions of the skull base. 17 However, due to its cost, not all health care systems can count on this technology. With regard to head and neck solid tumors, the American Joint Committee on Cancer states that CT scans of the neck and radiographs of the chest should be regularly performed for clinical examination.…”

“…[ 6 7 ] Several studies have been published on the use of CBCT technology for imaging of the temporal bone, specifically the middle and inner ear structures. [ 8 ] CBCT offers lower radiation dose, thinner slices, and provides reliable morphologic assessment of the temporal bone resulting from an increase in spatial resolution, when compared to Multidetector Computed Tomography (MDCT). [ 9 10 ] The Computed Tomographic Dose Index (CTDI) of an MDCT scan of the middle ear is around 170 mGy, compared to 15–30 mGy from CBCT imaging.…”

This is a case report of a 62-year-old male who presented to the Ear, Nose, and Throat clinic for a follow-up exam for hearing loss stemming from a fall from a horse in his infancy. A Cone Beam Computed Tomography (CBCT) examination revealed an intrapetrous communication between the internal jugular vein bulb and the superior petrosal sinus. Three-dimensional bone and soft tissues volume renderings were generated to demonstrate this incidental anatomical variant.
