    In recent years, autologous fat has been increasingly used for intracordal injection as a means of vocal rehabilitation in patients with deficient glottal closure, and the dipose tissue used has for the most part been harvested from the lower abdomen. However, patients differ considerably in the amount of fat available in the lower abdomen, and obtaining sufficient fat is often difficult in patents with a low body mass index (BMI). To overcome this problem we tried adopting a method that uses the buccal fat pad, as practiced in plastic surgery. The details of the method and the postoperative course are reported.
    The intracordal fat injection method for buccal fat pad tissue was performed in 10 cases during the 1-year from January 2005 to December 2005, and the patients' postoperative course was carefully monitored for more than 6 months after surgery.
    With the exception of one case, no signs of complications, such as swelling, infection, etc., were seen at the site of fat collection or in the vocal cord after the operation. Phonation was markedly improved after the injection, and the improvement was maintained throughout the observation period.
    Treatment of unilateral recurrent nerve paralysis by intracordal injection of autologous fat harvested from the buccal fat pad was successful.

    Carotid body tumors are uncommon neoplasms that arise at the bifurcation of the common carotid artery. Surgical resection is generally recommended, but entails an inherent risk of cranial nerves injury and excessive blood loss. Preoperative embolization has been reported to decrease blood loss and shorten resection time. In this study, we analyzed the benefits of preoperative embolization and the postoperative complications when preoperative embolization was performed.
    Six patients with seven tumors were treated between 1990 and 2005. Each patient's preoperative evaluation included CT, MRI, US, and angiography, and preoperative embolization was performed in four patients with five tumors.
    Blood loss, in the patients who underwent preoperative embolization, ranged from 20 ml to 900 ml (mean: 291ml), and operation time ranged from 4 hours 34 minutes to 6 hours 40 minutes (mean: 4 hours 55 minutes). In the group that did not undergo preoperative embolization, blood loss ranged from 642ml to 1390ml (mean: 1016ml), and operation time ranged from 9 hours 48 minutes to 10 hours 45 minutes (mean: 10 hours 17 minutes).
    Five patients had postoperative cranial nerve dysfunction, and it involved cranial nerve IX in one patient (14.3%), cranial nerve X in two patients (28.5%), and cranial nerve XII in five patients (71.4%). Resection of bilateral carotid body tumors in one patient resulted in baroreflex failure syndrome.
    In conclusion, preoperative embolization tends to decrease blood loss and shorten operation time, resulting in lower postoperative neurologic morbidity.
