Abstract:

Introdução: O seio esfenoidal apresenta relações anatômicas extremamente importantes com estruturas neurovasculares. Estas podem apresentar diversas variações, tornando as suas relações com seio esfenoidal bastante complexas e potencialmente associadas a graves lesões durante sua abordagem. Objetivo: O objetivo deste estudo prospectivo foi descrever, através da dissecção endoscópica em cadáveres, os detalhes das variações anatômicas do SE, avaliando a concordância entre os lados e as diferenças dessas variações entre o gênero e a cor da pele.

From May 2013 to June 2015 a total of 85 consecutive patients (68M, 17F), mean age 27.5 years referred to our surgical department. 75 patients had a primary sacrococcygeal pilonidal sinus, 10 patients had a recurrent pilonidal sinus and all underwent to E.P.Si.T. A fistuloscope is introduced through the external opening and the sinus cavity is completely ablated under direct vision. Patients' p

Bibliography: leaves 109-125. This thesis validated the use of sheep as a suitable animal model to study endoscopic sinus surgery (ESS) and to evaluate factors that may play a role in the healing of nasal epithelium after surgery. Nasal packing was shown to cause a significant injury and should be used by ESS surgeons with caution. Full-thickness wounds should be avoided in the nose where possible as the re-ciliation was significantly reduced when compared to partial-thickness wounds. In addition the healing of the nose took significantly longer than previously thought and was incomplete 84 da

Abstract:

Chronic rhinosinusitis (CRS) is a common sinonasal condition carrying a significant disease burden. Functional endoscopic sinus surgery (FESS) is often indicated where medical management fails. Middle turbinate lateralisation and adhesion formation (MiTLAF) is a common cause of failed FESS. Various MiTLAF prevention techniques have been described in the literature; however, no studies objectively analyse the physiological sequelae. This thesis reviews the literature regarding MiTLAF prevention techniques to determine the most efficacious and safe technique(s). As a proof of concept, computatio

Hypotheses: The primary hypothesis states; olfactory harvesting is a safe procedure and does not incur a reduction in nasal function including the sense of smell when compared to a control group. The secondary hypothesis states; ESS improves olfactory outcome in CRS patients with nasal polyps (CRSwNP) and CRS without nasal polyps (CRSsNP). Materials and Methods: Full Ethical and Research and Development (R&D) approval was granted; Ref: 05/Q0512/103. 131 patients were recruited over a 2 year period and non-randomised into the olfactory biopsy and control arms.

Although it is clear from a popular standpoint that CRS makes a negative influence on patient’s quality of life, the level of personal influence may vary widely from individual to individual. For patient’s perception, symptom severity can easily be classified as none, mild, moderate and severe. Medical treatment is reasonable to treat patients with mild symptoms of CRS.

Abstract:

Chronic rhinosinusitis (CRS) is chronic inflammation of the sinonasal mucosa. It is a disease of significant impact on public health, one that affects about 10-15% of the population. Functional Endoscopic Sinus Surgery (FESS) is the “gold standard” surgical treatment for CRS; its original philosophy or concepts are based upon the sinonasal mucociliary clearance studies by Messerklinger and Stammberger, which emphasize the role of the osteo-meatal complex (OMC). However, although the success rate of FESS is about 90%, there is a subgroup of patients who exhibit no improvement, and thus require

Full thickness injuries were created on the lateral nasal wall of sheep infested with Oestrus ovi. Sites of injury were packed on one side with hyaluronic acid (HA) packing or hyaluronic acid packing impregnated with insulin-like growth factor- 1 (HA+IGF1) in a randomized fashion. The opposite side was left unpacked as a control. Biopsies were obtained for light microscopy, scanning electron microscopy, and ciliary beat frequency (CBF) anal

In CAS, a correlation between a stored preoperative image data set and specific landmarks in the surgical area is required. However, studies on the performance of surface registration and comparisons between optic and electromagnetic navigation systems were lacking. Hence, the purpose of our

Four studies were performed to evaluate the influence of endoscopic sinus surgery (ESS) on the healing of nasal respiratory epithelium in a sheep model. The first study validated the sheep as a suitable animal model. As part of the standardization of the animal model a middle turbinectomy needed to be performed. The effects of middle turbinectomy on the nasal respiratory epithelium and cilial function were studied. At 3 weeks post turbinectomy the cilial function and histology of the respiratory epithelium was unchanged. The standardized and validated model could now be used to conduct further

Abstract:

Introduction: Endoscopic sinus surgery (ESS) is at present the gold standard therapeutic modality for chronic rhinosinusitis (CRS) resistant to medical therapy. Whilst results from ESS for CRS are generally good, postoperative bleeding and impaired wound healing with adhesion formation remains a concern. Due to patient discomfort and the detrimental effects on wound healing caused by most packing materials, many surgeons no longer routinely use nasal packing. Surgeons have in the past sought agents which would provide post-operative haemostasis without detrimentally affecting wound healing. An

Chronic Rhinosinusitis (CRS) is a recalcitrant disease, characterized by headache, nasal discharge / blockage, which substantially impairs daily functioning and negatively affect quality of life. Endoscopic Sinus Surgery (ESS) is an important treatment option for CRS, but has variable success rates. Biofilms are well organised heterogeneous communities of microbes embedded in a mosaic of extracellular matrix, adherent to biotic / abiotic surfaces. As they are resistant to host defences and medical treatments, they have been touted as possible pathogenic factors in CRS, which may perpetuate the
