RESUMEN

The diagnosis of cancer and its treatment have an incomparable impact on a patient's life. In the early postoperative stages after the surgical treatment of oral squamous cell carcinoma (OSCC), functions and well-being are limited, which leads to a fundamental decline of the quality of life (QoL). To date, no studies have been performed that focus on the development of special aspects during the time of the in-patient stay of OSCC patients. With the results of this cross-sectional study, we are able to identify those patients who tend to require special support. This cross-sectional study determined the postoperative QoL with a questionnaire (QU) that was handed out twice to OSCC patients after surgery during their inpatient stay. The questions were based on the European Organisation for Research and Treatment of Cancer (EORTC)'s Quality of Life Questionnaire (QLQ)-C30 and QLQ-H&N35. In our study, we found that for postoperative OSCC patients, eating, swallowing and speech were influenced the most. After decannulation, tracheotomy showed no impact on functions. Social contact was impaired at both timepoints. Especially female patients consider themselves to be more impaired on the scale of social contact. QoL should be checked with a standardized QU as an established tool during hospitalization in every oncology department. Only this procedure can pinpoint those patients who have struggles with their surgical outcome and need more assistance.

RESUMEN

PURPOSE: The purpose of the present study was to investigate the degree and clinical relevance of synovitis in craniomandibular dysfunction. MATERIALS AND METHODS: In total, 140 temporomandibular joints were examined using a 3 T MRI scanner. Quantitative analysis of synovial enhancement was performed and interrelated with arthrosis deformans, degenerative disc disease, joint effusion, bone marrow edema and restriction of motion. RESULTS: We found a statistically high and significant correlation between the degenerative changes as mentioned above and the intensity of synovial enhancement. CONCLUSION: The study shows that typical MRI findings in CMD patients are often combined with signs of synovitis. Presumably joint inflammation has an effect on the clinical signs and symptoms and also the prognosis of CMD. These results should be taken into consideration when selecting treatment. KEY POINTS: · 3T-MRI using a dedicated coil is the method of first choice in the examination of CMD syndrome.. · MR imaging allows quantification of increased synovial enhancement.. · There is a highly significant correlation between degenerative changes of the disc or cartilage and synovitis.. · Results of the study are relevant for the clinical assessment and therapy of CMD syndrome..

RESUMEN

BACKGROUND: Temporary tracheotomies are often used in oral microvascular flap reconstruction surgery to secure postoperative airway management and avoid emergency tracheotomies. Even when planned electively, a tracheotomy can cause severe and life-threatening complications. The aim of this study was to evaluate the complications of tracheotomies performed on oral cancer patients with microvascular flap reconstructions and differentiated patterns, which could lead to postoperative complications. METHODS: 150 patients, treated in the Department of Oral and Maxillofacial Surgery from March 2017 to August 2018, were included in this study. Patient records and perioperative data were analysed and the following specific items were evaluated: time after surgery until removal of the tracheal cannula, complications, cause and point of time of reinsertion of the cannula, anticoagulative treatment, ASA grade (American Society of Anaesthesiologists), TNM stage, and patient-specific data. RESULTS: 30 patients (20%) developed tracheotomy-associated complications, most commonly pneumonia (50%). There was a significant correlation between the time period until removal of the cannula and the occurrence of complications such as pneumonia and bleeding. CONCLUSION: The results of our study lead us to recommend continuing to perform temporary tracheotomies in oral cancer surgery with microvascular flap reconstruction. The overall complication rate is low and postoperative airway management can be performed in a safe and controlled manner. Nevertheless, the time period for the inserted cannula should be kept as short as possible.

RESUMEN

INTRODUCTION: Treatment decisions for fractures of the orbital floor are based on clinical appearance, ophthalmological examination, and computed tomography (CT) scans. In extensive fractures, decisions are easily made between conservative and surgical treatment. However, objective parameters are rare in inconclusive cases. MATERIALS AND METHODS: Our retrospective study included 106 patients with unilateral isolated orbital floor fractures. Correlations between preoperative ophthalmological examinations and specific CT parameters were performed. RESULTS: The defect size of the fracture appeared to be significantly associated with the presence of diplopia. CT-morphological parameters and preoperative ophthalmological results showed statistical significance for diplopia and incarceration of inferior rectus muscle (IRM), diplopia and displacement of IRM, decreased mobility and incarceration of IRM, and decreased mobility and displacement of IRM. DISCUSSION: Our clinical assessment scheme for CT scans of orbital floor fractures is aimed at facilitating treatment decision making using four CT-based variables. As critical size defects of the orbital floor of ≥2 cm2 are likely to cause clinically significant posterior displacement of the globe, resulting in enophthalmos, the proposed parameters offer a readily accessible and easy to evaluate scheme that helps to identify patients in need of surgical intervention.
