Distinguishing craniomorphometric characteristics and severity in metopic synostosis patients

The decision about which metopic synostosis patients should undergo surgery remains controversial. Multiple measures for radiographic severity have been developed in order to determine the optimal criteria for treatment. The aim of this study was to perform an extensive craniomorphometric analysis of patients who underwent surgery for metopic synostosis to validate and compare the various severity scales developed for this non-syndromic craniosynostosis. A comparative morphometric analysis was performed using computed tomography scans of preoperative metopic synostosis patients (n = 167) and normal controls (n = 44). Measurements included previous and newly developed metopic severity indices. Volumetric and area analyses were used to determine the degree of anterior cranial area and potential volume restrictions. Of the severity indices measured, the frontal angle, endocranial bifrontal angle (EBF), adjusted EBF (aEBF), anterior cranial fossa angle, horizontal cone angle, and bitemporal/biparietal distance ratio were significantly different in the metopic subjects relative to controls overall. However, metopic index, orbital rim angle, foramen ovale distance, and cranial volume exhibited no significant difference from controls. Only the frontal angle and aEBF correlated with the changes in anterior cranial dimensions observed in metopic synostosis. In conclusion, the frontal angle and aEBF provide the most accurate measures of severity in metopic synostosis.     

New method for quantification of the relative severity and (a)symmetry of isolated metopic synostosis

Trigonocephaly is the result of premature fusion of the metopic suture and its severity can vary widely. However, there is no gold standard for quantification of the severity. This study was performed to quantify severity using the Utrecht Cranial Shape Quantifier (UCSQ) and to assess forehead symmetry. Nineteen preoperative non-syndromic trigonocephaly patients (age ≤1 year) were included for the analysis of severity and symmetry. Severity according to the UCSQ was based on the following combined variables: forehead width and relative skull elongation. The UCSQ was compared to the most established quantification methods. A high correlation was found between the UCSQ and visual score (r = 0.71). Moderate to negligible correlation was found between the UCSQ and frontal angle, binocular distance, inter-ocular distance, and frontal stenosis. Additionally, correlation between the visual score and these established quantification methods was negligible. Assessment of the frontal peak (a)symmetry (ratio of right to left triangle area in the curve) showed a mean right versus left triangle area ratio of 1.4 (range 0.9–2.4). The results suggest that the UCSQ is appropriate for the quantification of severity based on the high correlation with clinical judgement. Furthermore, a larger triangle area right than left was unexpectedly found, indicating forehead asymmetry.     

Complications,risk factors,and patients-reported outcomes after skin-sparing mastectomy followed by breast reconstruction in women with BRCA mutations

Background: Women with a BRCA mutation have the option of undergoing prophylactic mastectomy and immediate breast reconstruction; however, the potential negative effects of reconstruction on women’s physical and psychological well-being are unclear. This study aimed to investigate complications, patient-reported pain, health-related quality-of-life (HRQoL) and satisfaction following reconstructive surgery at Oslo University Hospital between 2006 and 2013.

Methods: Data were collected retrospectively from the records of 238 patients. A cross-sectional survey was conducted to collect patient-reported HRQoL and satisfaction with outcome using the Short Form-12 questionnaires and Breast-Q. The self-administered Leeds assessment of neuropathic symptoms and signs was used to assess neuropathic pain.

Results: The majority of participants (89.5%) underwent implant-based breast reconstruction (IBBR); the remainder underwent autologous-tissue breast reconstruction (ATBR). Overall, 28.6% had complications within 30?days of surgery and 14.6% required resurgery because of complications. Women who underwent IBBR had a later onset of complications than those undergoing ATBR. Participants in the survey (n?=?175 of 219, response rate 79.9%) reported similar HRQoL to an age-matched general female population. Few (2.9%) reported neuropathic pain. Patients who underwent IBBR were significantly less satisfied with the reconstructed breast (p?=?.001) and overall outcome (p?=?.02) than those who underwent ATBR, but there were no significant differences in HRQoL scores between the two groups.

Conclusions: Overall, 28.6% of the women had complications within 30?days and 14.6% needed resurgery. Few had neuropathic pain. Women who underwent ATBR were more satisfied with the overall outcome than those who underwent IBBR.
