Purpose The purpose of this tutorial was to describe the surgical management of palate-related abnormalities associated with 22q11.2 deletion syndrome. Craniofacial differences in 22q11.2 deletion syndrome may include overt or occult clefting of the palate and/or lip along with oropharyngeal variances that may lead to velopharyngeal dysfunction. This chapter will describe these circumstances, including incidence, diagnosis, and indications for surgical intervention. Speech assessment and imaging of the velopharyngeal system will be discussed as it relates to preoperative evaluation and surgical decision making. Important for patients with 22q11.2 deletion syndrome is appropriate preoperative screening to assess for internal carotid artery positioning, cervical spine abnormalities, and obstructive sleep apnea. Timing of surgery as well as different techniques, common complications, and outcomes will also be discussed. Conclusion Management of velopharyngeal dysfunction in patients with 22q11.2 deletion syndrome is challenging and requires thoughtful preoperative assessment and planning as well as a careful surgical technique.

ABSTRACT We evaluated four patients who had occult intrasacral meningocele with multimodality radiographic imaging techniques. The clinical features, radiological findings, gross appearances of the lesion at surgery, surgical technique, histopathological features of the cyst wall, and surgical outcome are described. The role of magnetic resonance imaging in the preoperative evaluation compared with standard radiographic techniques is discussed. Theories regarding the pathogenesis of this lesion are reviewed.

Background: Detailed knowledge of the three-dimensional (3D) anatomical structures in precise treatment planning prior to implant placement is necessary. The choice of imaging techniques plays an important role in achieving the required information to measure exact dimensions. Cone beam computed tomography (CBCT) has increasingly been used for diagnosis and treatment in the fields of periodontology, endodontic, and orthodontics. It is also used as the preoperative evaluation of patients who are candidates for dental implant treatment. Dental implant placement is an important application of CBCT in dentistry. One of the features of CBCT is the possibility of changing the slice thickness while reviewing images. In this study, we examined the linear measurement accuracy of CBCT for determining the height of alveolar crest to the mental foramen in cross-sectional view with different slice thicknesses and in tangential view. Methods: We used five dry human mandibles in this study. Then the distance from the highest tip of alveolar crest to the upper border of mental foramen was measured by digital caliper (as gold standard) and on CBCT images in cross sectional view with 1, 3, 5, 7 and 9 mm slice thicknesses and in tangential view. Data were analyzed using IBM SPSS Statistics software version 22, paired t test, and inter class correlation. Results: Data were collected by evaluation of 5 dry mandible and 240 measurements. There were significant differences only in tangential view and 1 mm slice thickness option in cross-sectional view with the gold standard (P=0.003 and P=0.018 respectively). The results did not show any differences between the observers (P<0.001). Conclusions: Our results indicated that cross-sectional view is more accurate than tangential view, and 3 and 5 mm slice thicknesses are preferred for measurement.

The prevalence of descending thoracic aortic aneurysms (DTAs) and thoracoabdominal aortic aneurysms (TAAAs) are described. Imaging techniques and classification is given. Preoperative evaluation is described in detail, as prior to proceeding with repair of a DTA or a TAAA, patients must be thoroughly evaluated medically to determine if they are physiologically fit enough for repair. Indications for repair, primarily relating to size of aneurysm, are listed for both DTAs and TAAAs. Repair options and management for DTAs now includes thoracic endovascular aortic repair (TEVAR); its outcomes, benefits, and drawbacks are discussed in detail. The discussion of TAAAs is similar, with indications for repair and surgical management options given: direct open repair; a debranching procedure with subsequent endograft repair; and branched or fenestrated endograft repair. A table lists the symptoms attributable to thoracic and thoracoabdominal aortic aneurysms. Figures show the classification of DTAs; the evaluation of a patient with a thoracic aortic aneurysm; available thoracic endografts; anatomic restrictions for TEVAR; evaluation of a patient with a thoracoabdominal aneurysm; regional spinal cord hypothermic protection; distal aortic perfusion; visceral artery bypass; and a branched endograft.  This review contains 8 figures, 3 tables, and 125 references.

e16535 Background: Surgery is the central aspect of clinical management in patients with borderline ovarian tumors (BOT). As patients have excellent overall prognosis after successful surgery, perioperative morbidity is a critical point for decision regarding the primary surgical approach. Methods: Clinical and surgical parameters of patients undergoing surgery for primary BOT at two gynecologic cancer centers between 1993 and 2008 were analyzed with regard to perioperative morbidity depending on the surgical approach (laparoscopy vs. laparotomy). Results: A total of 105 patients were analyzed (44 with primary laparoscopy [42%], 61 with primary laparotomy [58%]). Primary laparoscopy was often performed with diagnostic intention and resulted in complete surgical staging in only 9.1% with subsequent formal indication for re-staging procedures. In contrast, complete surgical staging was achieved in 47.5% at primary laparotomy (p < 0.001). Tumor rupture was significantly more frequent during laparoscopy compared to laparotomy (29.5% vs. 13.1%, p = 0.038) but no other intraoperative complications were seen in laparoscopic surgery in contrast to 7 of 61 laparotomies (0% vs. 11.5%, p = 0.020). Postoperative complication rates were similar in both groups (19.7% vs. 18.2%, p = 0.848). Conclusions: Irrespective of the surgical approach, surgical management of BOT has acceptable rates of perioperative complications and morbidity. Choice of initial surgical approach can therefore be made independent of complication-concerns. As the recently published large retrospective AGO ROBOT study observed similar oncologic outcome for both approaches, laparoscopy should be considered as the preferred surgical approach for staging of patients with BOT if this appears feasible in preoperative evaluation.
