Characteristics of pulpal blood flow levels associated with non-segmented and segmented Le Fort I osteotomy.

Objectives: Laser Doppler flowmetry (LDF) is a noninvasive method to assess pulpal blood-flow (PBF). The purpose of this study was (1) to test whether Le Fort I (LF-I) osteotomy may show tooth type-related effects on LDF measurements, and (2) to investigate whether LF-I and tooth type may predict adverse PBF outcomes.

Material And Methods: PBF was recorded bilaterally in maxillary incisors, canines, and first premolars in a surgical group of patients who underwent a segmented (n = 14) or nonsegmented LF-I osteotomy (n = 12), and in a nonsurgical group of control subjects (n = 12) who did not undergo orthodontic treatment.

STAT1 activation in squamous cell cancer of the oral cavity: a potential predictive marker of response to adjuvant chemotherapy.

Background: For patients with squamous cell carcinoma of the oral cavity, both locoregional and distant recurrences are common, and an appropriate adjuvant treatment modality has yet to be defined. Thus, there is an urgent need to identify novel molecular markers with potential prognostic and/or predictive value to improve treatment outcome in these patients. This retrospective study was designed to investigate the predictive and/or prognostic value of STAT1 activation in squamous cell carcinoma of the oral cavity.

EpCAM expression in squamous cell carcinoma of the oral cavity: frequency and relationship to clinicopathologic features.

This retrospective study was designed to investigate the prognostic significance of EpCAM expression in human oral squamous cell carcinoma on a long-term follow-up. EpCAM expression was examined immunohistochemically on a tissue microarray (TMA) of paraffin embedded tissue specimens from 77 consecutive patients who underwent surgical treatment for squamous cell carcinoma of the oral cavity in the period between 1980 and 1997 at the Department of Craniomaxillofacial and Oral Surgery, Innsbruck Medical University. High EpCAM expression was found in 17 (22.

High EGFR expression predicts poor prognosis in patients with squamous cell carcinoma of the oral cavity and oropharynx: a TMA-based immunohistochemical analysis.

This retrospective study was designed to investigate the prognostic significance of EGFR overexpression in human oral squamous cell carcinoma on a long-term follow-up. EGFR expression was examined immunohistochemically on a tissue microarray (TMA) of paraffin embedded tissue specimens from 109 patients who underwent surgical treatment for squamous cell carcinoma of the oral cavity and oropharynx in the period between 1980 and 1997. High EGFR expression was found in 80 (73.

Effectiveness of ultrasonography in determining medial and lateral orbital wall fractures with a curved-array scanner.

Purpose: The purpose of the study was to evaluate the diagnostic value of ultrasonography to determine medial and lateral orbital wall fractures.

Materials And Methods: Sixty-two patients with the clinical diagnosis of an orbital trauma underwent coronal computed tomography (CCT) and ultrasonographic investigation (US). Inclusion criteria were clinically suspected orbital injuries defined by reduced bulbus motility, diplopia, or additional traumatic injuries of the orbit or the globe.

Evaluation of pulpal blood flow after tooth splinting of luxated permanent maxillary incisors.

Laser Doppler flowmetry (LDF) is a non-invasive method to assess pulpal blood flow (PBF). Dental injury has been associated with losses of pulpal sensibility. The purpose of this study was to assess whether LDF could be used to detect short- and long-term changes of PBF values of luxated permanent maxillary central incisors after repositioning and splinting.

Ultrasound versus computed tomography in the imaging of orbital floor fractures.

Purpose: The aim of the study was to investigate whether orbital ultrasonography (US) with a curved-array transducer could be an alternative imaging method to computed tomography (CT) to detect orbital wall fractures and fractures of the infraorbital rim.

Materials And Methods: Fifty-eight patients with the clinical ophthalmologic or radiologic diagnosis of an orbital trauma were investigated prospectively by US and CT. The reference method was the intraoperative findings.

Assessing revascularization of avulsed permanent maxillary incisors by laser Doppler flowmetry.

Background: Laser Doppler flowmetry, or LDF, is a noninvasive method used to assess pulpal blood flow, or PBF. Dental avulsion is associated with loss of pulpal sensitivity. The authors conducted this study to assess whether LDF could be used to detect revascularization of replanted teeth.

Clinical signs of orbital wall fractures as a function of anatomic location.

Objective: The objective of this study was to see whether clinical signs of medial orbital wall fractures distinguished these fractures from fractures of the lateral orbital wall and the orbital floor.

Study Design: The orbital fractures of 424 patients were analyzed. The patients were divided into 2 groups: (1) patients with orbital fractures with a medial orbital wall component and (2) patients with orbital fractures without a medial orbital wall component.

Orbital floor reconstruction with flexible Ethisorb patches: a retrospective long-term follow-up study.

Objective: The purpose of the study was to investigate whether a flexible, biodegradable material (Ethisorb) shows better long-term results with regard to diplopia, bulbus motility, and exophthalmos/enophthalmos compared to the use of lyophilized dura-patches and polydioxanone (PDS) foils.

Methods: During a period of 6 years 435 patients with an orbital fracture were investigated retrospectively. Inclusion criteria were patients with fractures of the orbital floor with a maximum size of 2 x 2 cm.
