Abstract Chordoma is not a benign disease. It grows invasively, has a high rate of local recurrence, metastasizes, and seeds in the surgical field.1 Thus, chordoma should be treated aggressively with radical resection that includes the soft tissue mass and the involved surrounding bone that contains islands of chordoma.2–5 High-dose radiation, commonly by proton beam therapy, is administered after gross total resection for long-term control. About half of chordoma cases occupy the cavernous sinus space and resecting this extension is crucial to obtain radical resection. Fortunately, the cavernous sinus proper extension is the easier part to remove and pre-existing cranial nerves deficit has good chance of recovery. As chordomas originate and are always present extradurally (prior to invading the dura), an extradural access to chordomas is the natural way for radical resection without brain manipulation. The zygomatic approach is key to the middle fossa, cavernous sinus, petrous apex, and infratemporal fossa; it minimizes the depth of field and is highly advantageous in chordoma located mainly lateral to the cavernous carotid artery.6–12 This article demonstrates the advantages of this approach, including the mobilization of the zygomatic arch alleviating temporal lobe retraction, the peeling of the middle fossa dura for exposure of the cavernous sinus, the safe dissection of the trigeminal and oculomotor nerves, and total control of the petrous and cavernous carotid artery. Tumor extensions to the sphenoid sinus, sella, petrous apex, and clivus can be removed. The patient is a 30-yr-old who consented for surgery.

Background: We tested the hypothesis that speckle-tracking strain imaging can quantify longitudinal right ventricular (RV) function and its association with left ventricular (LV) function in patients with myocardial infarction (MI). Methods: To quantify longitudinal RV function, 39 patients with old MI (OMI: LV ejection fraction 17 – 77 %, 45 ±16 %) and 29 age matched normal controls (Control: LV ejection fraction 65 ± 5 %) were studied with echocardiography. Longitudinal RV global peak systolic strain was assessed from apical four-chamber view using speckle-tracking imaging (EchoPAC, GE Electronic). RV fractional area change was also analyzed. Results: Longitudinal RV global peak systolic strain was significantly impaired in OMI compared to Control (−18 ± 5* and −25 ± 4 %, *p < 0.05 vs. Control) whereas RV fractional area change failed to discriminate from normal to impaired RV function (OMI: 48 ± 11 vs. Control: 52 ± 6 %, p = NS). When divided OMI into three groups regarding to plasma BNP level (Group A: BNP < 100 pg/ml; n = 14, Group B: 100 pg/ml ≤ BNP < 500 pg/ml; n = 14, and Group C; BNP ≥ 500 pg/ml; n = 11), Group A had no significant relations between longitudinal RV global peak systolic strain and LV ejection fraction (y = −0.07x − 11, r = 0.30, p = NS) whereas those were significantly correlated in Group B (y = −0.18x − 11, r = 0.59*, *p < 0.05). Furthermore, the strongest correlation between longitudinal RV global peak systolic strain and LV ejection fraction was observed in Group C (y = −0.58x + 5, r = 0.90*, *p < 0.05). Conclusion: Speckle tracking strain imaging quantified longitudinal RV global systolic function and exhibited its BNP-related dependency to LV systolic function in patents with OMI.
