Postoperative long-term results for the comparison of the symmetry of the upper lip during lip closure according to Millard and Pfeifer.

Background: Clefts in newborns are associated with severe morphological and functional impairment. Especially the lip is of importance as if the treatment result is unsatisfactory, it can lead to psychological changes in the patient. Different operative procedures have been developed over the last decades.

The incidence of occult metastasis and the status of elective neck dissection in salivary adenoid cystic carcinoma: a single center study.

Objective: Adenoid cystic carcinoma (ACC) is characterized by a high rate of local recurrence and late distant metastasis. The status of an elective neck dissection (END) is controversial in the literature.

Study Design: In this study we retrospectively analyzed the surgical treatment and follow-up examinations of 59 patients with ACCs of a salivary gland treated in a single center between 1980 and 2016.

Accuracy of Navigation-Guided Dental Implant Placement with Screw Versus Hand Template Fixation in the Edentulous Mandible.

Purpose: Preoperative planning of the implant position as part of a coordinated prosthetic and surgical concept is becoming increasingly important regarding function and esthetics. The aim of this study was to investigate the transmission accuracy of template fixation during surgery in edentulous arches with hand fixation in comparison to intermediary screw fixation.

Materials And Methods: Preoperatively, 10 implant positions were planned using computed tomography (CT) with the system med3D for implant placement in four mandible models of the Goettingen study model, using a prosthetic diagnostic template.

Clinical prognostic factors of salivary adenoid cystic carcinoma: A single-center analysis of 61 patients.

Purpose: Adenoid cystic carcinomas are rare malignant tumors of the salivary glands. They are characterized by a high rate of local recurrence, late distant metastasis and a poor disease-free survival. In this study, we analyzed a series of 61 patients who were all treated at the University of Göttingen over a period of 21.

Bacterial and histopathological findings in deep head and neck infections: a retrospective analysis.

Objectives: Deep neck infections are among the most dangerous acute diseases in the head and neck region. This analysis gives an overview of the bacterial and histopathologic findings of deep neck infections.

Study Design: From January 2002 to December 2012, 63 patients were diagnosed with and treated for deep neck infections at the University Medical Center Göttingen.

Osteoblast-like cells with different embryologic origins behave differently in increasing zoledronic acid concentrations: a pilot study in pigs.

Objective: We compared the intraindividual effects of increasing zoledronic acid (ZA) concentrations on osteoblast-like cells with different embryologic origins.

Study Design: Cultured osteoblast-like cells from mandible and iliac crest bone samples of domestic pigs were exposed to increasing concentrations of ZA (0, 10, 10, and 10 M). Proliferation was assessed by cell counting.

Can tongue shadow in panoramic radiographs be avoided by using the tongue repositioning maneuver?

Objective: The purpose of this study was to evaluate the use of the tongue repositioning maneuver (TRM) during panoramic radiography so as to avoid the error of tongue shadow.

Study Design: A total of 300 panoramic radiographs were evaluated. One hundred and fifty orthopantomograms with conventional positioning technique were used as a control group, while other 150 were taken with the patient performing the TRM.

Sialoendoscopy as a diagnostic and therapeutic option for obstructive diseases of the large salivary glands-a retrospective analysis.

Objectives: The diagnosis and therapy of obstructive inflammatory disorders of the salivary glands have changed in the past decades following the introduction of sialoendoscopy. The aims of the present study were to analyze the relevance of sialoendoscopy using our own data and to compare the results to those of other studies.

Patients And Methods: A retrospective analysis of 70 patients was performed, who were treated for obstructive disorders of the parotid and/or submandibular gland in whom sialoendoscopy was indicated.

A review of pathogenesis, diagnosis, treatment options, and differential diagnosis of odontogenic infections: a rather mundane pathology?

Odontogenic infections are common in the dental practice and their treatment should be a standard procedure for every dentist. For optimal management of septic intraoral problems, the practitioner must understand the underlying causes and etiologies of odontogenic infections. Therefore, the purpose of this article is to outline basic inflammatory processes involved in the development of odontogenic and intraoral infections including relevant pathogens, biochemical processes mediated by pro-inflammatory molecules, the basics of abscess formation, the host response, and the clinical appearance of intraoral septic processes.

Early disruption of the blood-brain barrier after thrombolytic therapy predicts hemorrhage in patients with acute stroke.

Background And Purpose: Leaks of the blood-brain barrier can be detected on postcontrast-enhanced T1-weighted MRIs. Although early disruptions of the blood-brain barrier appear to be an important risk factor for tissue plasminogen activator-related hemorrhages in rodents, little is known about their incidence and consequences in human stroke.

Methods: This is a retrospective analysis of a prospectively collected stroke database over the past 6 years.
