Kongressplakat pathologie dworak grading system prof. hansen_din a0
This study evaluated the Dworak tumor regression grading (TRG) system as a prognostic indicator for 159 rectal cancer patients treated with neoadjuvant chemoradiotherapy. Patients were observed for a mean of 42.5 months. A univariate Kaplan-Meier analysis found that patients with Dworak TRG grades 3+4 had a mean progression-free survival of 121 months, significantly higher than the 53.6 months for patients with grades 1+2. A multivariate analysis identified Dworak TRG grade and postoperative nodal stage as independent risk factors. The study concludes that Dworak TRG is an important prognostic indicator of progression-free survival and that subclassifying into grades 1+2 and 3
2018 kleinfeld-speech-paper-1
This study developed and tested a non-language specific speech test using made-up syllables to evaluate speech in cleft patients from different cultural and language backgrounds. The test was administered to 41 cleft patients and 39 non-cleft individuals from Germany, Iran, and India. Two speech pathologists independently rated audio recordings of the tests and found significant differences in hypernasality, nasal emissions, and consonant errors between cleft patients and non-cleft controls from the same language group. While inter-rater agreement was poor, the test was able to distinguish speech characteristics between cleft and non-cleft individuals across different languages and cultures.
2018 ghassemi-parotis-bjoms
This study evaluated the use of vascularised fatty tissue flaps to replace excised parotid tissue and prevent Frey's syndrome in 37 patients who underwent parotidectomy between 2008-2017. The fatty flaps took an average of 17 minutes to dissect and were stable for up to 9 years of follow up. None of the patients reported symptoms of Frey's syndrome such as flushing or sweating when eating. The flaps were an easy technique that avoided donor site morbidity compared to other options and successfully prevented Frey's syndrome in all patients.

2018 ghaneh-compsarsion
1) The study compared the effects of dexamethasone, tranexamic acid, and a combination of both on post-rhinoplasty edema and ecchymosis in 60 patients who underwent primary open rhinoplasty.
2) Patients were divided into 4 groups: dexamethasone only, tranexamic acid only, combination, and placebo. Medications were given intravenously before and after surgery.
3) Edema and ecchymosis were evaluated on a scale of 0-4 on postoperative days 1, 3, and 7. The dexamethasone, tranexamic acid, and combination groups had significantly lower edema and ecchymosis ratings compared to the placebo
2018 behrens-patient-spezcific
This study compared information obtained from standard computed tomographic angiography (s-CTA) scans and modified CTA (m-CTA) scans of the deep circumflex iliac artery (DCIA) flap to cadaver dissections. The m-CTA scans showed longer visible DCIA lengths, better visualization of branching patterns, and more detail on vessel course compared to s-CTA scans. However, s-CTA scans allowed bilateral evaluation while m-CTA only showed the injected side. Both CTA methods provided more information than cadaver dissections for preoperative planning of DCIA flaps.
2017 modabber-medial-approach-dcia-cad-cam
This document describes a new minimally invasive technique for harvesting a deep circumflex iliac artery (DCIA) flap for jaw reconstruction using virtual surgical planning and 3D printed surgical guides. Virtual planning based on CT scans allows for precise preoperative design of the bone flap and surgical guide. The guide enables a medial approach to the pelvis to harvest the flap, preserving important anatomical structures and muscles to reduce donor site morbidity. Initial results found the new technique allowed for shorter recovery times and less complaints about walking or hip profile changes compared to standard approaches.
2017 modabber-ear-aps
This study analyzed the three-dimensional morphology of ears in 240 Caucasian volunteers aged 21-65. 3D scans were taken and distances, angles, and proportions between landmarks on the ears were measured. The results showed that the distance between the subaurale and superaurale, as well as the width of the ear, significantly increased with age. The lower quadrant of the ear extended the most with increasing age. The ear continues changing shape in adulthood even after body growth stops. These measurements can help surgeons plan operations to achieve aesthetic outcomes for patients of different ages.
2017 jamilian-family history-cleft
This study assessed parental risk factors for cleft lip and palate (CL/P) in 187 children with CL/P and 190 non-cleft children. The study found that family history of clefts, lack of folic acid consumption during pregnancy, and consanguineous marriage were strongly associated with increased risk of a child being born with CL/P. Children with CL/P also had significantly higher rates of other congenital abnormalities and physical problems compared to non-cleft children. The findings suggest expecting mothers with a family history of CL/P or who engage in consanguineous marriages should take extra precautions to prevent CL/P in their children.

1) The document describes the case of a 90-year-old woman with metastatic Merkel cell carcinoma (MCC) that was treated with a combination of local and systemic immunotherapy.
2) Treatment included weekly intralesional injections of interferon alfa-2a along with topical imiquimod cream 3 times per week, as well as subcutaneous injections of pegylated interferon alfa-2b.
3) This combination led to the regression of all cutaneous metastases and lymph node metastases within 4 months, and the patient remained alive 30 months after starting immunotherapy, suggesting locally metastasized MCC can be controlled with local and systemic immunotherapy.
2016 movahedian- acellular-dermal-graft
1) The study examined the effect of using acellular dermal grafts in combination with Z-plasty technique for secondary cleft lip deformities.
2) 18 patients underwent scar revision, submucosal tunneling, Z-plasty, and placement of an acellular dermal graft.
3) Quantitative measurements before and after surgery found significant improvements in symmetry, defect height, and lip thickness, indicating acellular dermal grafts with Z-plasty can effectively treat secondary cleft lip deformities.
2016 ghassemi-nasal reconstr-threelayer
This document describes a technique for reconstructing full-thickness defects of the lower third of the nose using a three-layer approach. A reversed nasolabial flap is used to reconstruct the nasal lining, an auricular cartilage graft provides structural support, and a forehead flap provides skin coverage. The technique was used in 21 patients and resulted in satisfactory aesthetic and functional outcomes in most cases. Combined flaps from local and distant sites incorporating cartilage can effectively reconstruct large nasal defects while restoring the three anatomical layers.
2016 heinz-two-step reconstruction of non-marginal auricular defects
This document describes a two-step surgical technique for reconstructing non-marginal full-thickness defects of the auricle. In the first step, tissue from the preauricular and retroauricular regions is used to reconstruct the anterior and posterior surfaces of the auricle defect. In the second step, performed two weeks later, the tissue pedicles are separated and adjusted. Thirteen patients underwent this procedure with excellent esthetic outcomes, low morbidity, and patient satisfaction. Vertical and horizontal dimensions of the reconstructed auricles changed minimally. The two-step technique provides an improved method for reconstructing central auricle defects.
2016 ghassemi-maxillary advancement versus man
This study retrospectively evaluated 34 patients with class III dentofacial deformities who underwent either maxillary advancement or mandibular setback surgery. Pre- and post-operative lateral cephalograms were analyzed to compare changes in 14 soft tissue parameters between the two surgical approaches. Statistically significant differences were found for cervical length, which increased after maxillary advancement but decreased after mandibular setback. Some other aesthetic parameters were found to be superior after maxillary advancement compared to mandibular setback. The study aims to help determine the best surgical approach for correcting class III deformities while optimizing aesthetic outcomes.
2016 ghassemi-clinically-usable-fib-ilium
This study compared the clinically usable bone regions of the ilium and fibula for mandible reconstruction. Measurements were taken of 241 ilia, 91 mandibles, and 60 fibulas. The ilium offered a similar total usable bone length to the fibula but maintained a more constant bone thickness throughout, whereas the fibula's dimensions varied significantly. In some fibulas, only a small portion of the total bone length could actually be used. The study suggests the ilium may be a better donor site than the fibula, especially for women requiring occlusal rehabilitation after mandible reconstruction.
2016 bartella-face-lift-gesichtsrekonstruktion-2
This study compared outcomes of 86 patients who underwent reconstruction of facial soft tissue defects following tumor excision using various surgical techniques, including non-vascularised skin grafts, local flaps, a modified face-lift technique, and microvascular free flaps. The face-lift technique resulted in shorter hospital stays and lower rates of ectropion than other methods for defects under 60 cm2. It provided the best aesthetic outcomes but was limited to smaller defects. Microvascular free flaps were necessary for the largest defects over 60 cm2 due to the amount of tissue needed.

This document describes a surgical technique using an anterior pedicled retroauricular flap (APRF) to reconstruct full-thickness defects of the central non-marginal area of the ear. The APRF is harvested from the postauricular skin in two stages and used to reconstruct both the posterior and anterior surfaces of the defect. The procedure was performed successfully in 11 patients to repair conchal defects, with good aesthetic outcomes, minimal donor site morbidity, and high patient satisfaction. The APRF provides an effective method to reconstruct central ear defects while maintaining ear size and shape with minimal stress on the flap.
2015 ghassemi-nose-reconst-esth-procedure
This document discusses the use of techniques from aesthetic rhinoplasty in reconstructive nasal surgery after tumor resection. The authors used osteotomy and tip shaping techniques in 17 patients to reshape the nasal framework after removing underlying bone or cartilage. This increased the margin of safety and reduced the size of the defect, allowing tension-free primary closure with local tissue flaps. Patients were satisfied with the aesthetic and functional outcomes. The techniques require knowledge of procedures from aesthetic rhinoplasty but can improve reconstruction results.
2015 ghassemi-maxillary advancment2015
This study evaluated the effect of maxillary advancement of less than 6 mm versus 6 mm or more on soft tissue changes in 53 patients treated for Class III malocclusion. For advancements under 6 mm, there were no significant changes in the nasolabial angle but significant changes in lip and chin positions. For advancements of 6 mm or more, submental and nasolabial soft tissues significantly improved, indicating better aesthetics. The degree of maxillary advancement significantly impacts soft tissue changes and should be considered in treatment planning.
2015 ghassemi-histologie-vessel-pedicled
This study examined the arterial walls of commonly used free flaps to determine histopathological differences and the influence of age, gender, and side. Light microscopic examinations were performed on 245 arterial specimens from cadavers. The peroneal artery showed the greatest atherosclerotic changes, followed by the radial artery, inferior epigastric artery, deep circumflex iliac artery, and circumflex scapular artery. Age had a significant effect on the radial and peroneal arteries. Anatomic side was an important factor for the peroneal and deep circumflex iliac arteries, while gender had little influence. The findings suggest vessel selection for flaps should consider these histological differences related to age, side, and gender
2014 ghassemi-u-considering the f
This study evaluated the effect of different amounts of mandibular setback surgery on the submental region and aesthetics. The study examined 38 patients who underwent mandibular setback surgery, distinguishing those with less than 5mm of setback from those with 5mm or more. The results found no significant changes in the submental region or aesthetics for patients with less than 5mm of setback. However, for patients with 5mm or more of setback, there were significant decreases in cervical length and changes to the lip-chin-throat angle, lower lip length, and upper lip length. The study suggests these factors should be considered in surgical planning to avoid undesirable aesthetic impacts of mandibular setback surgery.
2014 ghassemi-factor-influencing
This study investigated factors that influence the need for preoperative vascular imaging before harvesting a vascularized fibular flap. The researchers analyzed 185 angiograms and found significant correlations between lower extremity artery pathology and risk factors like high cholesterol, high blood pressure, coronary heart disease, diabetes, and increased age. Specifically, increased age was the strongest predictor of vessel pathology. The study concludes that preoperative vascular imaging should be performed in patients with medical comorbidities to reduce the risks of flap failure and donor site complications when harvesting a fibular flap.
2013 modabber-zygoma-reconstruction
This document describes a study that evaluated the accuracy of using computer-assisted virtual surgical planning and guides for reconstructing zygomatic bone defects with vascularized iliac crest bone grafts. CT scans of patients' faces and bone grafts were used to create 3D models and virtual surgical plans. Surgical guides were fabricated to transfer the plans intraoperatively. Postoperative CT scans found the mean difference in bone graft shape and position between actual and planned was 0.71mm and 3.53mm respectively, indicating good accuracy of the computer-assisted method.
