Surgical Management of Skull Base Chondroblastoma

Abstract

Gross total or near total resection of skull base chondroblastomas through lateral skull base approaches results in long-term tumor control and low complication rates.

Chondroblastoma of the Clivus: Case Report and Review

“…There is insufficient data to predict tumor behavior in craniofacial chondroblastoma. Malignant degeneration to chondrosarcoma is likely rare but has been previously reported, 11 and some authors have suggested that lesions with an intratumoral aneurysmal bone cyst may behave more aggressively.…”

Chondroblastoma of the temporal bone

“…The suture is anterosuperior to the external auditory canal and anatomically very close to TMJ [10]. Most patients with temporal bone chondroblastomas were older than those with tumors at the usual site, the ages ranged from 8 years to 85 years old, with a mean of 39.4 [4,11]. Of the 45 patients, 20 were male and 25 were female, and there was a variety of symptoms.…”

“…Most of these tumors commonly arise in the epiphysis of the long bones, and tumors of the temporal bones are extremely rare [1]. A chondroblastoma of the temporal bone was first reported by Denko and Krauel in 1955, and since then, around 70 cases have been reported [2][3][4]. We report a case of chondroblastoma of the temporal bone, and review the literature to discuss the clinical presentation, radiological and pathological findings, as well as surgical management strategies.…”

“…34 patients (76%) presented with otologic complaints, including hearing loss, tinnitus, otalgia, otorrhea and vertigo, and 12 patients (27%) complained of a temporal mass or swelling, whereas 11 patients (24%) presented with difficulties of mastication and TMJ symptoms [3,4,8,12]. In terms of neurological complaints, 6 patients (13%) presented with headache or seizures, 7 patients (16%) presented with facial palsy, and 1 patient presented with a lower cranial nerve dysfunction [4]. The duration of symptoms was known in 41 cases, and ranged from 20 days to 10 years, with a mean of 15 months [13].…”

“…The patient exhibited the typical symptoms of chondroblastoma including hearing loss, tinnitus, otalgia, otorrhea and pain on TMJ movement. Compared to the mean length of follow-up (3.6 years) from 36 cases, our patient was followed up for a relatively long period of seven and a half years after surgery [4,14].…”
