Tunneled Paranasal Augmentation Using Diced Autologous Costal Cartilage in Asian Rhinoplasty: A Comparative Study.

Due to the prevalence of anterior maxilla dysplasia in Asian population, paranasal concavity is a common accompaniment to low nose, but its impact on facial harmonization is often underestimated. A retrospective comparative study was conducted on patients diagnosed as low nose with paranasal concavity between June 2017 and June 2021, with a total of 56 patients followed up successfully. The control and observation groups were established according to whether the paranasal augmentation was performed. Demographic data were collected. Cosmetic enhancement was quantitatively evaluated by sagittal planimetry, establishing related anatomical landmarks and measuring columella base prominence (CBP) and alar base prominence (ABP). Subjective evaluation concluded the patient-reported satisfaction (FACE-Q-Rhinoplasty Module and Facial Appearance Module) and the third-party physician assessment (Global Aesthetic Improvement Scale, GAIS).Significant improvements in CBP and ABP were reported both in the control and the observation group (p < 0.01). In postoperative intergroup comparisons, the observation group was superior to the control group regarding ABP values (2.5 ± 0.75 degrees, p < 0.01), FACE-Q-Facial scores (7.49 ± 3.70, p < 0.05), and GAIS scores (p < 0.05). However, no statistical difference was found in CBP values and FACE-Q-Rhinoplasty scores. Paranasal augmentation-related complications included asymmetry of alar bases (6.9%) and facial or intraoral foreign body sensation (34.5%). This study affirmed that paranasal augmentation using diced costal cartilage in rhinoplasty is a safe procedure effective in remedying paranasal concavity and improving facial satisfaction. LEVEL OF EVIDENCE:: IV.

Autologous ribcartilage-silicone composite dorsal onlay graft in augmentation rhinoplasty / 中华医学美学美容杂志

Objective:To introduce a method of combining autologous rib graft and a silicone plate as a composite graft for augmentation rhinoplasty.Methods:Twenty-two female patients were included in this series. Eleven cases had unsatisfactory nasal appearance Nine cases were admitted for postoperative graft warping, and refused to harvest a second costal cartilage, thirteen cases had limited amount of rib graft for harvest. When cartilage was insufficient for a full dorsal onlay graft, a L-shaped silicone nasal implant would be used and carved into a plate-like, so as to make into a composite graft with the cartilage on top of the silicone plate.Results:Up to 12-month follow-up was conducted, averaged 6.2 months. One case exhibited temporary ischemic signs at the incisions, resolved by compressive taping at day 5.For all other 21 cases aesthetic outcomes were satisfactory with no graft infection, extrusion or other complications. The dorsal only graft did not significantly transilluminate.Conclusions:Rib-silicone composite dorsal graft is an applicable and safe method in augmentation rhinoplasty surgeries, particularly when there is limited amount of cartilage available.

Effect of fine construction of cartilage scaffold in nasal reconstruction / 中华医学美学美容杂志

Objective:To explore the method of constructing nasal cartilage scaffold with fine refinement.Methods:From 2010 to 2018, 212 patients with nasal reconstruction were admitted to the Center of Rhinoplasty and Reconstructive Surgery Hospital of Chinese Academy of Medical Sciences.Results:The stent structure of all patients was composed of nasal dorsal graft, nasal alar support graft, nasal columella support graft, shield graft, lateral nasal cartilage support graft, hat graft, etc.Conclusions:The reconstructed nose presents a more delicate appearance after the later modification compared with the traditional simple l-shaped cartilage stent, and the patient satisfaction is high.

Primary rhinoplasty for female patients utilizing autologous costal cartilage transplantation / 中华整形外科杂志

Objective@#The purpose is to investigate the validity of a surgical technique that utilizes autologous costal cartilage grafts in primary rhinoplasty for female patients.@*Methods@#From July 2015 to July 2017, 137 cases received primary rhinoplasty with various types of grafts originated from autologous costal cartilage to correct the unpleasant nasal appearances including low dorsum, poorly defined nasal tip and wide alar base.@*Results@#With 6 to 36 months follow-up, six patients(4.3%) exhibited noticeable changes in nasal contour due to graft warping. Revision surgeries were commenced to correct those minor deformities, resulting in satisfactory outcome.All other cases presented significant improvements of the nasal appearance.@*Conclusions@#Autologous costal cartilage is a good source for primary rhinoplasty cases.

Application of Ultrasonically Activated Scalpel in Laparoscopic Intestinal Adhesion Release / 中国普外基础与临床杂志

Objective To study the application of ultrasonically activated scalpel in laparoscopic intestinal adhesion release.Methods Intestinal adhesion release with ultrasonically activated scalpel under laparoscope was performed in 29 patients suffered from intestinal adhesive obstruction after gynecological operation. Results All operations were successfully performed, and none of them converted into open surgery. Intestinal disruption occurred durring operation in 2 patients with extensive intestinal denseadhesion which were mended successfully under laparoscope. The operative duration was 30-150 min (mean 45 min). Postoperative complications such as bowel leak age, bleeding, abdominal infection were not experienced. Postoperative hospital stay was 3-7 days (mean 4 days). No case had relapse symptom such as abdominal distention or pain after 1-24 months of follow up. Conclusion Compared with electric scalpel, ultrasonically activated scalpel can improve the operative safety, lessen tissue damage, shorten operative time, and reduce the chance of relapse in laparoscopic operation in gynecology.

Laparoscopic hernioplasty in 50 cases / 中国实用外科杂志

ObjectiveTo study the method,indications, advantage and shortcoming of laparoscopic repair of inguinal hernia. MethodsFrom Jun. 1995 to Jun. 2000,50 patients with inguinal hernia were treated with laparoscopy. There were 34 indirect inguinal hernia, 9 direct inguinal hernia and 7 concealed hernia. The transabdominal preperitoneal laparoscopic mesh repair of hernia(TAPP) was performed in 34 patients. Closure of the internal orifice of hernia was performed in 7 patients. Totally extraperitoneal repair was performed in 9 patients. ResultsAll cases were operated successfully. The mean operation time was 59.3(15～180) mins. The average length of postoperative stay was 5.4(3～7)days. There were no death record and no conversion operation. There was one early failure owing to the use of too small a piece of mesh. There has been no long-term recurrence. ConclusionThe results indicate that mesh repair of hernias is a satisfactory technique with a low recurrence rate and a low major complication rate.
