A New Technique

The purpose of this study is to describe a new technique for en bloc temporal bone resection using a diamond threadwire saw (T-saw) as an alternative to cutting the temporal bone with an osteotome. This technique has been performed in 10 patients with external auditory canal and middle ear cancers without any injury to the internal carotid artery or jugular vein. The authors conclude that the use of a diamond threadwire saw after transposing the internal carotid artery anteriorly is a safe, simple, and reliable technique for en bloc temporal bone resection.

Because of unsatisfactory results in treatment of malignant conditions of the temporal bone, a technique for total en bloc resection of the temporal bone and carotid artery was reported by Graham et al. in 1984. The procedure involves resection of the internal carotid artery, cranial nerves VI through XII, and structures adjacent to the temporal bone. Experience with two additional cases led to numerous modifications in the recommended procedure, as reported by Sataloff and Myers. Additional clinical experience with this technique and its complications has resulted in further modification. Additional pitfalls and specific changes in technique from previous reports are discussed in detail, including a new procedure to assure the adequacy of contralateral venous outflow.

Basilar Tip Aneurysm

Abstract For two cases of a high basilar tip aneurysm accompanied by a short intracranial internal carotid artery, the orbitozygomatic temporopolar approach consisting of an en bloc fronto-orbitozygomatic temporal craniotomy and temporopolar approach was carried out. On angiograms, the height of the bifurcation of an elongated basilar artery and the length of the intracranial internal carotid artery from the interclinoid line between the anterior and posterior clinoid processes were 20 mm and 6 mm in Case 1, and 18 mm and 5 mm in Case 2. respectively. The skin flap was separated subfascially to preserve the frontotemporal branch of the facial nerve. The fronto-orbitozygomatic temporal bone flap was made, and a part of the basal bony structures of the orbital roof, the sphenoid ridge, and the temporal bone were removed. The basilar tip aneurysm could be seen and clipped easily by upward and oblique viewing from below through the wide operative space consisting of the less retracted internal carotid and middle cerebral arteries, the oculomotor nerve, the tentorial hiatus, and the emptied anterior temporal fossa obtained by partial division of the temporal bridging veins. The operative procedure is presented in detail and compared with other surgical approaches that have been described previously.

AbstractA 36-year-old male with a primary chondroid is presented. This tumour arose from the base of the temporal bone and extended to the mastoid cavity. It involved the facial nerve and was adherent to the internal jugular vein and internal carotid artery. The tumour was excised and the patient has been carefully followed up for 10 years. He has shown no evidence of local recurrence, intracranial extension of the residual tumour and distant metastasis.

Abstract OBJECTIVE This study was undertaken to define more accurately the feasibility and indications of the contralateral pterional approach to ophthalmic segment aneurysms of the internal carotid artery (ICA). METHODS Between 1995 and 1999, 46 patients with ophthalmic segment aneurysms of the ICA were surgically treated in our institution. Eleven of the 46 aneurysms were operated using the contralateral pterional approach. All aneurysms were successfully clipped without complications; three patients required bone resection around the aneurysm neck. We studied the 11 patients who were treated with the contralateral approach by defining six parameters to assess the feasibility of the approach and to predict the necessity for bone resection: 1) Parameter A, the distance between the anterior aspect of the optic chiasm and the limbus sphenoidale; 2) Parameter B, the distance between the bilateral optic nerves at the entrance to the optic canal; 3) Parameter C, the interrelation of the optic nerve and the ICA, expressed as a/b in which a is the length from the midline to the optic nerve and b is the length from the midline to the ICA; 4) Parameter D, the size of the aneurysm neck; 5) Parameter E, the direction of the aneurysm from the ICA wall on the anteroposterior angiogram; and 6) Parameter F, the distance from the medial side of the estimated distal dural ring to the proximal aneurysm neck on the lateral angiogram. RESULTS Parameters A to F were 8.8 mm (range, 5.4–11.1 mm), 14.5 mm (range, 10.4–22.2 mm), 0.9 mm (range, 0.6–1.3 mm), and 3.0 mm (range, 2.3–4.7 mm), 5 to 160 degrees, and 1.3 mm (range, 0.3–2.4 mm), respectively. All patients had excellent operative outcomes without visual dysfunction. Three patients required drilling of the bone around the optic canal on the craniotomy side; bone drilling was not required when Parameter E was between 30 and 160 degrees and Parameter F was more than 1 mm. CONCLUSION Parameters A to D are important for assessing the feasibility of the contralateral approach to ICA-ophthalmic segment aneurysms, and Parameters E and F are most useful for calculating the difficulty of this approach.

AbstractObjective:To draw attention to the possibility of an aberrant internal carotid artery behind an intact tympanic membrane presenting as a middle-ear mass.Case:A 48-year-old female patient presented with a hearing impairment in her right ear that had started 10 years ago. Otoscopic examination revealed a retro-tympanic mass. A high resolution computed tomography scan of the temporal bone was performed that showed protrusion of the internal carotid artery into the middle ear. Magnetic resonance angiography provided excellent visualisation of the internal carotid artery. Finally, a diagnosis of an aberrant internal carotid artery was made and the patient was evaluated with a conservative approach.Conclusion:All retro-tympanic masses should ideally be visualised with a computed tomography scan of the temporal bone before any middle-ear surgery, such as tympanotomy and biopsy, and it is essential for every otologist who undertakes myringotomy and middle-ear surgery to know about this rare entity.
