ABSTRACT
Crushed cartilage is used in rhinoplasties and crushing carry the risk of devitalization. The most infero-posterior part of the septal cartilage has a rough surface compared with the smooth surface of the remaining parts. This cartilage may be more convenient for crushing with lesser pressure requirements, increasing the viability. Twenty-six patients underwent septorhinoplasty and the infero-posterior part of the septal cartilage was harvested. The rough cartilage was utilized in nine patients (excluded from the study). Seventeen patients were included in the study. The mean age of the patients was 28 (19-37y). Two pairs of grafts were utilized for histological study. In fifteen patients crushing experiment was performed. The smooth-surfaced cartilages were the control group, the rough-surfaced cartilages were the study group. For each case, grafts were reduced to the same dimensions and placed over millimetric-paper and photographed. The grafts were crushed simultaneously. The crushed cartilages were also placed on millimetric-paper and photographed. The data were evaluated statistically. The mean surface increment ratio was 2.26 ± 0.28 for the control and 2.94 ± 0.25 for the study group. The difference was statistically significant (p < 0.0048). In two specimen, after applying hematoxylin & eosin stain, the extracellular matrix of the rough cartilage specimen stained darker due to more abundant proteoglycan content. The rough septal cartilage widens more compared with the smooth cartilage under the same crushing pressure. Thus, the rough cartilage requires lesser pressure for widening which may increase the viability. The rough septal cartilage contains more proteoglycan which may explain its softness.
ABSTRACT
BACKGROUND: The purpose of the study was to determine the prevalence of omental metastasis in endometrioid adenocarcinoma and to correlate risk variables with this spread. METHODS: A retrospective analysis of patients with endometrioid adenocarcinoma who underwent omentectomy in addition to staging laparotomy was performed. RESULTS: Omental metastases were noted in 11 of the 322 patients with endometrioid adenocarcinoma (3.4%). Multivariate analyses showed that there was a significant correlation between omental metastasis and positive peritoneal cytology, adnexal involvement, and grade 3 tumor (p = 0.028, p = 0.001, and p = 0.01, respectively). There was no statistical relationship between omental metastasis and lymphovascular space involvement, deep myometrial invasion, and lymph node metastasis (p = 0.087, p = 0.97, and p = 0.92, respectively). CONCLUSION: Grade 3 endometrioid adenocarcinomas, especially those that are complicated by deep myometrial invasion, have a pattern of intra-abdominal spread similar to more aggressive endometrial cancers, with frequent involvement of the omentum. Overall, we conclude that 37.5% (3/8) of patients who had a grade 3 tumor and omental metastasis stage IV disease would have been missed if a staging operation similar to that employed for ovarian cancer had not been performed.
