“…Jugulo-tympanic tumours are generally classified by either the Fisch or Glasscock-Jackson staging systems [52][53][54][55]. The detail shown in the CT and MRI scans together enable accurate staging, greatly assisting selection of surgical approaches.…”

Head and Neck Paraganglioma: Medical Assessment, Management, and Literature Update

Head and neck paraganglioma (HNPGL) are rare, highly vascular; typically slow growing and mostly benign neoplasms arising from paraganglia cells. HNPGL cause morbidity via mass effect on adjacent structures (particularly the cranial nerves), invasion of the skull base and, rarely, catecholamine secretion with associated systemic effects. The last decade has seen significant progress in the understanding of HNPGL genetics, with pertinent implications for diagnostic assessment and management of patients and their relatives. The implicated genes code for three of the five subunits of mitochondrial enzyme succinate dehydrogenase (SDH); recent literature reports that approximately one third of all HNPGL are associated with SDH mutations-a prevalence significantly greater than traditionally thought. There are distinct phenotypical syndromes associated with mutations in each individual SDH subunit (SDHD, SDHB, SDHC, and SDHAF2). This article focuses on the clinical features of HNPGL, the implications of HNPGL genetics, and the current evidence relating to optimal identification, investigation, and management options in HNPGL, which are supported by reference to a personal series of 60 cases. HNPGL require a systematic and thorough assessment to appropriately guide management decisions, and a suggested algorithm is presented in this article. Recent developments are particularly pertinent to surgeons of multiple disciplines, including otolaryngology, neurosurgery, vascular, and general surgery.

“…21 This began with a modified ''lazy S'' incision, essentially a combination of a hemicoronal scalp incision and a postauricular otologic incision. A frontotemporal craniotomy with zygomatic arch osteotomy was performed, with careful preservation of the temporalis muscle, to access the intradural portion of the tumor.…”

Concurrent Cochlear Implantation with Resection of Skull Base Hemangiopericytoma Following Sudden Deafness in an Only-Hearing Ear

A 72-year-old man with a known left acoustic neuroma, left-sided deafness, and a recently diagnosed right infratemporal fossa (ITF) hemangiopericytoma, presented with sudden deafness in his right ear. Imaging revealed right-sided skull base extension and a large intracranial tumor component. The patient underwent a frontotemporal crainiotomy with concomitant ITF approach. Complete tumor resection was possible, though invasion of the otic capsule was present. Immediately postresection, a cochlear implant (CI) was performed via a transmastoid approach. Full electrode insertion was achieved and confirmed by visualization through the dehiscent middle fossa floor. Mastoid obliteration was then performed with a free fat graft. Postoperative imaging confirmed complete tumor resection (Simpson grade I) and adequate CI placement. Follow-up magnetic resonance imaging was performed at 6 and 12 months, and no tumor recurrence was seen. Prior to CI activation, the patient was completely deaf bilaterally. At 18-month follow-up, however, excellent hearing was achieved with the right CI (16 of 22 electrodes active), and the patient is now conversational with no obvious deficit. His cognitive function is excellent, corresponding to preoperative status, and he is independent in his activities of daily living. Following adjuvant radiation, our patient remains disease free at 18 months.

“…24 It was performed via a modified infratemporal fossa approach, based on the Fisch approach for surgically removing extensive glomus jugulare tumors. 19,20 After proximal and distal occlusion of the aneurysm, the intervening affected portion of the artery was removed and a primary end-toend anastomosis was performed. 24 This approach is quite invasive because it involves extensive petrous bone drilling, facial nerve transposition, mandibular condylectomy, and transection and closure of the external ear canal.…”

Aneurysms arising in the petrous segment of the internal carotid artery (ICA) are rare. Although the causes of petrous ICA aneurysms remain unclear, traumatic, infectious, and congenital origins have been implicated in their development. These lesions can be detected incidentally on routine neuroimaging. Patients can also present with a wide spectrum of signs and symptoms, including cranial nerve palsies, Horner syndrome, pulsatile tinnitus, epistaxis, and otorrhagia. The treatment of petrous ICA aneurysms remains challenging. Treatment options include close observation, endovascular therapies, and surgical trapping with or without revascularization. Management dilemmas exist, particularly for incidental lesions found in asymptomatic patients. The authors review the literature and discuss the anatomy of the petrous ICA as well as the pathophysiological features of aneurysms arising in this region, and they propose a management paradigm with current treatment options.
