AbstractObjectives:We describe a rare case of spontaneous temporomandibular joint herniation into the external auditory canal, and we also review the presentation, aetiology and management of such cases.Case report:An 87-year-old woman presented with a four-month history of left-sided otorrhoea and otalgia. Examination revealed a soft, polypoid mass in the left ear canal. When the patient opened her mouth the lesion disappeared. Subsequent computed tomographic imaging of the patient's temporal bones confirmed an 8.6 mm defect in the antero-inferior portion of the left ear canal, with herniation of retrodiscal soft tissues.Conclusion:The external auditory canal is intimately related to the temporomandibular joint, separated only by its bony anterior wall. Neoplasm, trauma or inflammation in this area can result in displacement of the temporomandibular joint into the ear canal; however, spontaneous herniation is rare. Persistence of the primitive foramen of Huschke can result in dehiscence of the anterior canal wall, allowing articular tissue to prolapse into the ear canal. Surgical closure of these defects is known to be effective in ameliorating symptomatic cases.

This report describes the clinical and radiographic findings together with surgical management of temporomandibular joint contents herniation through the tympanic plate of the external auditory canal. Two patients are reported. A review of the literature is presented, including a brief discussion of the embryological development of the external auditory canal. Excluding infection, trauma or neoplasm, the defect in the tympanic plate of the external auditory canal represents a developmental aberration with failure of the foramen of Huschke to close during development.A pre-auricular approach with insertion and fixation of an onlay polyethylene implant to prevent prolapse of the peri-articular tissues into the ear canal is presented and described.

AbstractA 64-year-old Qatari female, with a one-year history of right otorrhoea and deafness, had a reddish-white mass projecting into the right ear canal, through the tympanic membrane, that proved histopathologically to be a paraganglioma. Computerized tomography (CT) of the temporal bones showed extensive destruction of the right mastoid bone, the posterior ear canal wall, and the sinus plate, with total disruption of the ossicles, simulating a malignant tumour, which is unusual for a middle ear paraganglioma.

AbstractObjectives:To describe the clinical features of external auditory canal cholesteatoma, and to assess the outcome following bony meatoplasty with tragal cartilage and perichondrium graft repair.Methods:A retrospective review was carried out, comprising all patients with external auditory canal cholesteatoma who presented between January 2007 and December 2011. Patients underwent pre-operative audiometry and computed tomography imaging of the temporal bones, before undergoing bony meatoplasty via a postauricular incision. Pre- and post-operative comparisons were made of patients' otological symptoms and the otoscopic appearance of the external ear canal.Results and conclusion:Eight patients were included in the analyses. The median age of patients was 46.5 years (range 14–68 years), with a male to female ratio of 1:1. The median length of follow up was 16 months. The most common presenting features were unilateral otalgia and purulent otorrhoea. All patients had relatively advanced disease at presentation, with erosion of the temporal bone. All patients underwent bony meatoplasty via a postauricular approach to eradicate the disease. Bony meatoplasty was successful in the definitive management of external ear canal cholesteatoma.

Foramen Of Huschke

A congenital defect of the anterior wall of the external auditory canal (EAC) is known as foramen of Huschke. The tympanic bone is incompletely developed and has a U shape at birth. The foramen of Huschke closes via continuous bone growth, which occurs before the age of 5 years. A persistent foramen of Huschke is an anatomic variation located in the anteroinferior portion of EAC, which can cause ear discomfort with spontaneous temporomandibular joint (TMJ) herniation into the EAC bony defect. We present a case of 50-year-old man who had a symptomatic TMJ herniation through an osseous defect. The physical examination showed a bulging mass of anterioinferior portion of EAC when the patient closed his mouth, which was retracted when the mouth openned. We report a case of surgical reconstruction of the EAC wall defect, and the foramen of Huschke with titanium mesh via preauricular approach along with literature’s review.

Abstract Background Tension pneumocephalus is an increasing air trapped intracranially. Either spontaneous, post-traumatic or iatrogenic in origin. Cystic angiomatosis is a benign vascular hamartoma of the skeleton, when acquired it is either due to trauma or infection. This is the second report in English literature of post-traumatic delayed tension pneumocephalus with the development of cystic angiomatosis of the skull bone. Case presentation A 55-year-old gentlemen, presented with scalp swelling of 6-month duration with history of head trauma 2 years back. The swelling was increasing and associated with progressive walking difficulties and left hearing loss. CT scan and MRI revealed extradural pneumocephalus, parietal and occipital pneumatocele, and multiple lytic bony lesions, left mastoid hyperpneumatization with inner table defect communicating with the extradural space. Diagnosis of delayed extradural tension pneumocephalus was made. Surgical exploration revealed multiple bony defects of parietal, temporal and squamous part of left temporal bones, confirmed extradural pneumocephalus with intact dura. Repair of mastoid defect of (0.5 × 0.5 cm), excision of pneumatocele and removal of lytic bones were performed. Defective bone “cribriform-like” was identified at occipital and parietal regions centrally with a defect of nearly 7 × 7 cm. Future cranioplasty was considered after 6 months. Histology of bony chips and surrounding soft tissues is recognized as cystic angiomatosis. Conclusions The present case developed two very rare complications, following trivial head trauma; the first complication was delayed extradural tension pneumocephalus with pneumatocele which presented 2 years after trauma, the origin of air was from a defect of the inner table of the mastoid, the second complication was cystic angiomatosis of the skull bones. Both complications were managed surgically in one operative session as a combined neurosurgery and otolaryngology teams approach.

Objective: To explore the otoscopy, CT and MRI features of spontaneous temporomandibular joint(TMJ）herniation(STMJH) into the external auditory canal (EAC) through the persistent foramen of Huschke (PFH). Methods: 15 cases diagnosed STMJH were collected. The otoscopy, CT data of 15 cases and MRI data of 6 cases were retrospectively reviewed. Results: Otoscopy revealed a mass located in the anterior wall of the bony EAC that moved forwards and backwards during mouth opening and closing, respectively. CT showed a soft mass with bony defect in the anterior wall of the EAC, with no enhancement; the bony defect margin was well defined in all cases. The bone adjacent to the PFH was pressed and partially wrapped around the soft mass, as if “holding a ball,” in seven cases. Pseudobone shell around the soft mass was observed in eight cases. Six cases included MRI scans, which showed TMJ soft tissue herniated into the EAC. Conclusion: STMJHs have unique otoscopic, CT and MRI features. The examination strategy recommended is dynamic otoscopy and conventional CT, MRI can be chosen when the herniation is complicated by infection or otitis externa or when the patient has TMJ dysfunction; conservative management and follow-up observations are the main treatment strategy recommended. Advances in knowledge: Mechanical stress of TMJ on the EAC is thought to cause herniation and the special CT features, the location and size of the PFH, especially the location, are the major risk factors for TMJ herniation in patients with FH.

Abstract OBJECTIVE AND IMPORTANCE Only two cases of primary intracranial myxomas have been described previously in the literature: one patient had a primary intracranial myxoma in the pituitary fossa, and the other patient's myxoma was located in the posterior fossa. CLINICAL PRESENTATION A rare case of primary myxoma of the temporal bone in a 17-year-old boy is described. The patient presented with a history of progressive left-sided hearing loss and increasing headaches of a few months' duration. INTERVENTION An initial draining procedure in the left ear revealed extant mucous material, and further investigation showed a large calcified lesion involving the petrous and temporal bones and filling the middle fossa. At surgery, a large mucoid-appearing tumor was removed. The tumor pathology revealed a primary myxoma with bone and meningeal involvement. No clinical or histopathological evidence that it was a metastatic lesion was found. CONCLUSION The features of myxomas on computed tomographic and magnetic resonance imaging, the histopathology, and surgical considerations are discussed.
