  • Sialoendoscopy-Assisted Sialolithectomy for Submandibular
    J Oral Maxillofac Surg 71:295-301, 2013 Sialoendoscopy-Assisted Sialolithectomy for Submandibular Hilar Calculi Deng-Gao Liu, SMD,* Lan Jiang, SMD,† Xiao-Yan Xie, SMD,‡ Zu-Yan Zhang, DDS, PhD,§ Lei Zhang, SMD,ʈ and Guang-Yan Yu, PhD, DDS¶ Purpose: To assess the clinical effects of endoscopy-assisted sialolithectomy for submandibular hilar calculi. Materials and Methods: The present study was undertaken in 70 patients with symptomatic stones in the hilum of submandibular glands who underwent endoscopy-assisted sialolithectomy from Decem- ber 2005 through March 2011 in the Peking University School and Hospital of Stomatology. The operative data were analyzed retrospectively. All patients were followed periodically postoperatively. Submandib- ular gland function was investigated by postoperative symptoms, clinical examinations, sialography, and scintigraphy. Results: Submandibular stones were successfully removed in 65 patients, with a success rate of 92.9%. Temporary lingual nerve injury occurred in 1 patient. Two patients developed ranulae and underwent an uneventful sublingual gland excision. During a mean follow-up of 23 months (range, 6 to 55 mo), 52 of 65 patients were symptom free, whereas 11 patients complained of occasional swelling of the affected gland at mealtimes and 2 patients developed a recurrent stone. Thirty patients underwent postoperative sialography. The sialographic appearances included 4 types: 1) approximately normal; 2) the main duct was significantly dilated at the hilum, but no persistent contrast was seen on the functional film; 3) the main duct was significantly dilated in the hilar region, and persistent contrast was seen at the dilated hilum of the functional film; 4) the main duct was dilated or strictured, and persistent contrast was seen on the functional film.

However, we believe that this is slowly starting to change. With increased attention on head and neck cancer, the Research and Education Foundation believes this is an opportunity to strengthen and expand our impact. With your commitment to the Foundation, we can reverse the trend of declining funding for head and neck cancer research! Presently the Research and Education Foundation supports two research awards each year. We are proud to fund these grants but there are more to cover. We would like to create more opportunities for young clinicians and researchers to explore unique and innovative treatments which may one day lead to a cure. To do as much, the Foundation needs to increase its asset base. There are three targeted ways for you to support the Foundation which are designed to provide immediate revenue as well as to increase the capital base for the long term with the goal of generating increased annual income perpetually to support more research. The support opportunities include: 1. Legacy gifts, such as estate planning, single premium life insurance and charitable lead annuity trusts (CLATs), are meaningful ways to create continuous and sustainable growth for the Foundation in the years and decades to come.

Two kinds of custom-made micro-endoscopes (ME) were tested in ex vivo vas deferens specimen and in post-mortem whole body. The semi-rigid ME included a micro-optic (0.9 mm outer diameter [OD], 10.000 pixels, 120° vision angle [VE], 3–20 mm field depth [FD]) and an integrated fibre-optic light source. The flexible ME was composed of a micro-optic (OD = 0.6 mm, 6.000 pixels, 120° VE, 3–20 mm FD). The ex vivo study included retrograde investigation of the vas deferens (surgical specimen n = 9, radical prostatectomy n = 3).
