ObjectiveTo investigate the effectiveness of comprehensive rhinoplasty with autogenous costal cartilage grafting and prosthesis augmentation rhinoplasty in the treatment of secondary nasal deformity with saddle nasal deformity after cleft lip surgery. MethodsThe clinical data of 96 patients with secondary nasal deformity with saddle nasal deformity after cleft lip surgery between September 2008 and January 2019 were retrospectively analyzed. There were 17 males and 79 females with an average age of 25.6 years (range, 17-38 years). Autogenous costal cartilage grafts were used to construct stable nasal tip framework and enhance the strength of alar cartilage. Nasal dorsum prostheses (39 cases of bulge, 45 cases of silicone prosthesis) or autogenous costal cartilage (12 cases) were used for comprehensive rhinoplasty. Visual analogue scale (VAS) score was used to evaluate the postoperative satisfaction subjectively, and nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle were calculated to evaluate objectively before and after operation. ResultsAll patients were followed up 6 months to 8 years, with an average of 13.4 months. Nasal septal hematoma occurred in 3 patients after operation, which was improved after local aspiration and nasal pressure packing. Two cases had mild deformation of the rib cartilage graft of the nasal dorsum, one of which had no obvious deviation of the nasal dorsum and was not given special treatment, and one case underwent the cartilage graft of the nasal dorsum removed and replaced with silicone prosthesis. The incisions of the other patients healed by first intention, and there was no complication such as postoperative infection and prosthesis displacement. The nasal alar height symmetry index, nasal alar width symmetry index, nasal dorsum central axis deviation angle, and nasal columella deviation angle significantly improved after operation when compared with preoperative ones (P<0.05). Postoperative subjective satisfaction evaluation reached the level of basic satisfaction or above, and most of them were very satisfied. Conclusion Comprehensive rhinoplasty using autologous rib cartilage grafting to construct a stable nasal tip support, combined with dorsal nasal prosthesis or autologous cartilage implantation, can achieve good effectiveness on secondary nasal deformity with saddle nasal deformity after cleft lip surgery.
Objective To investigate the technical points and effectiveness of autogenous costal cartilage transplantation in repair of Binder’s syndrome. Methods Between June 2012 and June 2017, 8 cases of Binder’s syndrome were admitted. There were 3 males and 5 females, aged 16-31 years (mean, 22 years). All patients were conformed to the typical manifestations of Binder’s syndrome. The autogenous costal cartilage was harvested and carved into the nasal dorsum graft, nasal column graft, and nasal basement graft. Before and after operation, standard pictures of the anterior view, lateral view, and base view were taken to measure facial related parameters of nasal dorsum length, nasal columella-lobule ratio, nasofrontal angle, nasal columella-upper lip angle, nasal tip projection rate, and nasion projection. Then the effectiveness of this surgical procedure for Binder’s syndrome was evaluated. Results All incisions healed by first intention without acute infections. All patients were followed up 6-36 months, with an average of 18 months. The foreign body sensation in upper lip and scar hyperplasia in thoracic incision occurred in 1 case, respectively. The nasal morphology improved significantly and the coordinated relationships of the nose with the upper lip and face were restored postoperatively. Postoperative parameter measurements were taken in 6 cases. The nasal dorsum length, nasal columella-lobule ratio, nasofrontal angle, nasal columella-upper lip angle, nasal tip projection rate, and nasion projection at preoperation were significantly improved when compared with the values at 6 months after operation (P<0.05). The difference in nasal dorsum length, nasal tip projection rate, and nasion projection between actual values at 6 months after operation and normal values was no significant (P<0.05). There was significant difference in nasal columella-lobule ratio between actual value at 6 months after operation and normal value (P>0.05). Conclusion Autogenous costal cartilage transplantation in repair of Binder’s syndrome can obviously improve patients’ appearance of the external nose and middle face, and obtain the persistent effectiveness.
ObjectiveTo evaluate the effectiveness of autologous costal cartilage-based open rhinoplasty in the correction of secondary unilateral cleft lip nasal deformity.MethodsBetween January 2013 and June 2020, 30 patients with secondary unilateral cleft lip nasal deformity were treated, including 13 males and 17 females; aged 14-41 years, with an average of 21.7 years. Among them, 18 cases were cleft lip, 9 cases were cleft lip and palate, and 3 cases were cleft lip and palate with cleft alveolar. The autologous costal cartilage-based open rhinoplasty was used for the treatment, and the alar annular graft was used to correct the collapsed alar of the affected side. Before operation and at 6-12 months after operation, photos were taken in the anteroposterior position, nasal base position, oblique position, and left and right lateral positions, and the following indicators were measured: rhinofacial angle, nasolabial angle, deviation angle of central axis of columella, nostril height to width ratio, and bilateral nasal symmetry index (including nostril height, nostril width, and nostril height to width ratio).ResultsThe incisions healed by first intention after operation, and no complications such as acute infection occurred. All 30 patients were followed up 6 months to 2 years, with an average of 15.2 months. During the follow-up, the patients’ nasal shape remained good, the tip of the nose and columella were basically centered, the back of the nose was raised, the collapse of the affected side of nasal alar and the movement of the feet outside the nasal alar were all lessened than preoperatively. The basement was elevated compared to the front, and no cartilage was exposed or infection occurred. None of the patients had obvious cartilage absorption and recurrence of drooping nose. Except for the bilateral nostril width symmetry index before and after operation, there was no significant difference (t=1.950, P=0.061), the other indexes were significantly improved after operation when compared with preoperatively (P<0.05). Eleven patients (36.7%) requested revision operation, and the results were satisfactory after revision. The rest of the patients’ nasal deformities were greatly improved at one time, and they were satisfied with the effectiveness.ConclusionAutologous costal cartilage-based open rhinoplasty with the alar annular graft is a safe and effective treatment for secondary unilateral cleft lip nasal deformity.

ObjectiveTo discuss the clinical application and effectiveness of autologous costal cartilage transplantation in the repair of upper lip depression in the secondary repair of cleft lip.MethodsThe clinical data of 10 patients of secondary repair of upper lip depression with cleft lip by autologous costal cartilage transplantation between January 2017 and January 2019 were retrospectively analysed. There were 7 males and 3 females with an average age of 24 years (range, 18-33 years). There were 8 cases of bilateral lip fissure and 2 cases of unilateral lip fissure. All of them underwent early lip repair at the age of 2-3 years old. The change of the profile of the soft tissue profile of the upper lip of the patient was quantitatively analyzed before operation and at immediate after operation, including the soft tissue facial angle (G-Sn-Pg’), the nasolabial angle (Cm-Sn-UL), the mentolabial angle (UL-LL-Pg’), the distance between the most salient point of the upper lip to the aesthetic plane (UL-E), the highest point of the frontal part, the projection distance of the most salient point of the upper lip on the plane of the orbital ear (G-UL), and the upper lip protrusion (ULP).ResultsOne case had incision infection and healed after dressing change, and in the other 9 patients, the incisions healed by first intention, and no acute infection and other complications occurred. The appearance of the lateral morphology of the upper lip at immediate after operation was significantly improved when compared with that before operation. The value of UL-LL-Pg’, UL-E, G-UL, and ULP were significantly increased and G-Sn-Pg’ was significantly decreased when compared with preoperative ones (P<0.05). There was no significant difference in Cm-Sn-UL between pre- and post-operation (t=0.821, P=0.433). All the 10 patients were followed up 6-24 months, with an average of 15 months. During the follow-up, the soft tissue morphology of the upper lip was good. No long-term complications such as cartilage absorption and cartilage displacement were found.ConclusionAutologous costal cartilage transplantation is a safe and effective treatment for upper lip depression in the secondary repair of cleft lip.
ObjectiveTo explore the effectiveness of transplantation of engraved autologous costal cartilage for individualized surgical management in secondary rhinoplasty for cleft lip. MethodsBetween September 2009 and January 2014, 350 patients with secondary nasal deformity of cleft lip were treated, including 160 males and 190 females with a mean age of 18.2 years (range, 16-56 years). Nasal deformity was caused by unilateral cleft lip in 200 cases and by bilateral cleft lip in 150 cases. The interval of lip repair and nasal deformity correction was 2-50 years (mean, 12 years). About a 2-6 cm cartilage was harvested from the 6th or 7th costal cartilage, and was engraved to the shape of "ge" in Chinese. The upper part was strengthened on both sides of the alar cartilage; the lower part was fastened to columella and nasal septum cartilages. The rest of cartilages was diced into 0.1 mm×0.1 mm×0.1 mm cubes. The columella incision was designed to "Z"-plasty, and was stretched to the nasion along alar edge. The engraved autologous costal cartilage was transplanted and fixed to the collapse of nostril. The cartilage cube was transplanted and filled into the collapse of nasal root to achieve the aesthetic effect of nasal augmentation. The effectiveness was evaluated according to the grade of secondary rhinoplasty for cleft lip by ZHANG Li et al. at 1, 6, and 12 months after operation. ResultsAll incisions were primary healing. All patients were followed up 1-12 months (mean, 6 months). After rhinoplasty, the collapse of nostrils was lifted, and the shape and height of collapse of nostrils were symmetrical to normal side. The deflection of columella nasi was corrected. A beautiful shape of nose was achieved. The excellent and good rates were 98.6% at 1 month, 97.4% at 6 months, and 97.1% at 12 months after operation, showing no significant difference (χ2=0.545, P=0.761). ConclusionThe technique of transplantation of engraved autologous costal cartilage for individualized surgical management in secondary rhinoplasty for cleft lip can achieve excellent surgery effect.
ObjectiveTo explore the feasibil ity to repair defect on the neck and chest with the rectus abdominis flap which pedicle is lengthened by measuring the width, thickness, and the intercostal space of the inferior costicartilage using CT angiography (CTA). MethodsThirty cases receiving CTA and three-dimensional reconstruction between July and December 2013 were included in the study. Of 30 cases, 17 were male and 13 were female, aged 44-70 years (mean, 56 years). The width and thickness of the 3rd to 7th costicartilages and the distance of the 3rd to 6th intercostal spaces were measured, and the lengthened pedicle was calculated after the 4th to 7th costicartilage was cut off. Between July 2012 and November 2013, the lengthened pedicle of the rectus abdominis flap was cl inically used to repair the defect on the neck and chest in 4 cases. ResultsThe pedicle of the rectus abdominis flap was about 6 cm in length. When the left 7th, 6th, 5th, and 4th costicartilages were cut off, the average pedicle was lengthened by 4.07, 7.99, 12.50, and 17.48 cm respectively; when the right 7th, 6th, 5th, and 4th costicartilages were cut off, the average pedicle was lengthened by 4.63, 10.82, 16.64, and 22.05 cm respectively. In 4 flaps which were cl inically used to repair defects, 3 flap completely survived, 1 flap had partial necrosis. Three patients were followed up 6 months, and the appearance and texture of the flap were satisfactory; 1 patient failed to be followed up. ConclusionResecting the inferior costicartilage can prolong the pedicle of the rectus abdominis flap, therefore it can be used to repair defect on the upper chest and the neck.
ObjectiveTo explore the effect of the expanded capsule on the growth of autogenous costal cartilage. MethodsSixteen New Zealand white rabbits at the age of 3 months (weighing, 2.2-2.5 kg; male or female) were selected and four 15 mL tissue expanders were implanted on the back symmetrically. After 1 month, the expanded capsule formed, the tissue expanders were removed; the capsule of the left side was removed (experimental group), and the capsule of the right side was reserved (control group); meanwhile, the right 7th and 8th costal cartilage without the perichondrium was divided into segments and placed into the capsule of 2 groups symmetrically. At 4 and 8 weeks after transplantation, the cartilage was harvested for the general, weighing, and histological observations. ResultsOne rabbit died during the experiment, and the other 15 rabbits survived. The differences of cartilage weight between before and after transplantation showed more obvious increase in the experimental group[(0.003 4±0.002 7) g and (0.005 8±0.001 4) g] than those in the control group[(-0.000 3±0.001 9) g and (-0.003 9±0.005 3) g] at 4 and 8 weeks, showing significant differences between 2 gouprs (t=4.331, P=0.029; t=6.688, P=0.008). The change of cartilage weight at 8 weeks was significantly higher than that at 4 weeks in the experimental group (t=-3.098, P=0.001); but the change of cartilage weight at 8 weeks was significantly lower than that at 4 weeks in the control group (t=2.491, P=0.009). The histological observation showed that the activity of the cartilage was enhanced in 2 groups at 4 and 8 weeks when compared with normal cartilage, and more obvious change was observed in the experimental group than in the control group. And the acellular area was seen in the cartilage at 8 weeks in the control group. The Masson staining results showed that the color was deeper in the experimental group than in the control group. ConclusionThe removal of the expanded capsule during operation is beneficial to the growth of autogenous costal cartilage. The results can provide corresponding experimental guidance for the clinical problems.
