RESUMEN
BACKGROUND: The most prevalent form of facial bone fractures is nasal fractures. The surgical procedures used for these fractures are relatively simple, but complete correction is not easy because the nasal bone is small and identifying the fracture site by palpation is difficult. This study aimed to investigate the efficacy of intraoperative surgical navigation systems in nasal bone fracture surgery through a prospective analysis. METHODS: Between February 2019 and July 2019, 25 navigation-assisted closed reductions of nasal fractures were performed. Preoperative computed tomography images were obtained at 1-mm intervals before surgery and the navigation was set by a simulation to have an error rate of less than 1. Then, the navigation system was used to identify the fracture site. Closed reduction was performed with Asch forceps and a Langenbeck elevator based on the previous markings made using the navigation system. RESULTS: The degree of reduction was evaluated by plain X-rays and computed tomography scans, which were performed 1 month after surgery. In the navigation group, the average distance between the fragment and normal bony alignment was decreased from 2.38 to 0.49âmm and the modified Motomura score was an average of 2.40 points. The decrease in the mean distance was significantly different (Pâ=â0.038) compared with the conventional group. CONCLUSIONS: Surgical navigation systems could be a useful tool for localizing fracture sites and guiding closed reductions. In particular, the system could be recommended for nasal bone fracture reductions in the tip or pyriform regions, which are difficult to correct. LEVEL OF EVIDENCE: II.

BACKGROUND: Free abdominal tissue transfer is considered the gold standard for autologous breast reconstruction. However, many plastic surgeons are concerned about the theoretical risk of flap-related or donor-site complications associated with previous abdominal surgery. Also, studies have reported conflicting results in the literature due to difference in surgical strategies used in each study. This study analyzes the effect of prior incision on the complications and risk factors in our institution. METHODS: In this retrospective cohort study, we analyzed a total of 122 patients who had undergone reconstructive surgery between March 2012 and February 2019. To assess the effect of prior incision, we divided all patients into a scar group (n=59) and a control group (n=63). Based on our operative approach, patient demographics and postoperative complications were analyzed. RESULTS: No significant differences were found between patients in the scar group and the control group in flap-related (13.3% vs. 16.4%, P=0.62) and donor-site complications (31.7% vs. 31.4%, P=0.67). In binary logistic regression modeling, only diabetes mellitus was significantly related with donor-site complications (P=0.030). CONCLUSIONS: This result suggested that previous abdominal scars are no longer a reluctant factor for breast reconstruction using an abdominal flap, when an appropriate flap design was used and the surgical techniques were tailored to each scar. In patients with vertical midline or subcostal scar, it requires careful preoperative planning with CT angiography and attentive follow-up are needed.
RESUMEN
BACKGROUND: Although the initial projection after primary nipple reconstruction is excellent, nipple projection gradually flattens in most cases due to multiple causes. Although various methods have been reported to rebuild the nipple after nipple flattening, the most effective method of secondary nipple reconstruction remains unknown. The aim of this study was to review our institution's experiences with secondary nipple reconstruction. METHODS: We conducted a retrospective review from March 2012 to January 2019. We performed secondary nipple reconstruction if the primary reconstructed nipple height differed by more than 6 mm from the normal nipple height. We chose the method of nipple revision according to the degree of tissue scarring and the remaining nipple projection. RESULTS: We performed secondary nipple reconstruction on a total of 27 nipples, using pursestring sutures for 19 nipples and star flaps in eight nipples. The median follow-up period was 8 months (range, 6-19 months) after the final nipple reconstruction. Among the 19 nipples reconstructed using purse-string sutures, 10 (53%) demonstrated acceptable projection of more than 5 mm. Among the eight nipples reconstructed using star flaps, six (75%) showed acceptable projection of more than 5 mm. Most of the patients (73%) were satisfied (scores of 4 or 5) with the nipple reconstruction overall. CONCLUSIONS: Few studies have presented favorable outcomes of secondary nipple reconstruction. When the star flap and purse-string suture methods were used depending on the remaining nipple height and scarring, appropriate projection could be achieved.
