Title: Modified technique of zygomatic implant for edentulous rehabilitation in patients with atrophic jaw and patients with ectodermal dysplasia
Biography:
Dr. Nhan Van Vo completed a Master Implant degree in UCLA University in 2012, and received a Ph.D. in Odonto-Stomatology in 2015. He is the first Vietnamese dentist performed zygomatic implant placement and mandibular nerve respositioning for dental implant placement simultaneously. His research area is on bone reconstruction of severe atrophic jaw for dental implant rehabilitation. His most recent research was the alternative treatment in patients with ectodermal dysplasia. He is honored to be invited speaker at international conferences all over the world. He is also author of articles on bone resconstruction and dental implant rehabilitation on reputed maxillofacial journals.
Abstract:
Full mouth rehabilitation in edentulous patients, especially in patient with ectodermal dysplasia is considered as a challenge for implant surgeons because of the severe atrophy of these patients' alveolar ridges. Traditional protocol using zygomatic implants or conventional implants remains some disadvantages of risk of soft-tissue infection and difficulty in practicing oral hygiene, high rate of sinusitis and increased stress on the implant head. Objectives: To evaluate the satisfaction, the improvement of quality life of patients and the outcome of modified technique of zygomatic implant for maxillary edentulous patients. Methods: Sixteen patients with severely atrophic edentulous maxilla and two ectodermal dysplasia patients were enrolled using the modified technique of zygomatic implant. Total 56 zygomatic implants, 30 standard implants were used in follow up times of 1 to 5 years. All patients were investigated the bone volume and sinus pathology by Cone Beam computed tomography and used the Nobel Clinician software (Nobel Biocare, Switzerland) for treatment plans. Findings: All implant showed good osseointegration. The survival rate of both zygomatic implants and standard implants are 100%. No infections or inflammations of soft tissue around implants were recorded. Final restorations were stable and retentive restoring patient’s chewing function and aesthetic. All patients were satisfied with final prostheses that significantly improve their quality of life. Conclusions: Zygomatic implant with modified technique is a predictable procedure that overcomes disadvantages of traditional protocol in edentulous rehabilitation of severely atrophic jaw and in patients with ectodermal dysplasia, especially significantly improved the patient’s quality of life.

Abstract:
The Hippocratic dictum states that war is the best school for surgeons. A perfect exemplar of this is the life of Sir Harold Gillies, who pioneered the techniques of plastic surgery and, in particular, the pedicle flap during World War I. His work and tutelage not only encouraged an entire cadre of future surgeons but also played a vital role in the recovery, both mental and physical, of a great number of patients. His legacy of meticulous planning and preparation stands firm today.

Abstract:
In parotid surgeries most commonly faced complication is iatrogenic facial palsy, To decrease the incidence of this complication many landmarks are being used to identify the facial nerve like Tragal pointer, Tympanomastoid suture line, Posterior belly of Digastric muscle, Digastric ridge, Retrograde tracing from marginal mandibular branch of facial. Even with the use of the above landmarks sometimes identification of facial nerve becomes difficult due to distortion of anatomy by tumor and in revision surgeries. There is an incidence of around 40% of transient and 17% of complete facial palsy is parotid surgeries and the risk increases in malignant and revision cases. In this study we tried to explore the possibility of using the Posterior auricular artery as a new landmark for facial nerve identification in parotid surgeries. Our study was done on 12 cadaveric hemifaces where we identified the posterior auricular artery along with its stylomastoid branch and their relation with facial nerve and other predetermined landmarks was measured followed by a high definition photography. We found a fairly consistent and stable relation of posterior auricular artery to facial nerve and surrounding structures. Our results show an average distance of 6.49mm and a range of 5-7 mm between posterior auricular artery and facial nerve. With our results we propose that post auricular artery can be used as a safe and reliable land mark for facial nerve in parotid surgeries, especially in tumours located high up in parotid gland.
