Twentytwo patients with deviation of nasal septum were treated by modified septorhinoplasty. The main points in the modification were:(1) The incision was curved instead of "L" shaped. It would avoid the disadvantage of having tension on the suture line and poor exposure;(2) Using triangle osteotomy to correct deviation of nasal septum, it was less traumatic and lessbleeding and better correction. The results from followup were as follows:18 good and 4 fair. The techniques and advantages of the modified procedure were discussed.
The noses of eight patients being dead for 2hours were dissected to investigate the layers andstructure of the nose, and the stability of theimplanted silicone noae prosthesis was tested.According to the structure and microstructure ofthe nose studied by us, we suggested a newconcept of nasal muscle and dorsal deepfasciacomplex. We confirmed the prcathesis should beimplanted in the space between the nasal boneand the complex. The reason for complicationhappened in this approach was that...
ObjectiveTo explore the clinical efficacy of modified polytetrafluoroethylene (PTFE) prosthesis rhinoplasty for correction of low nose and short columella. MethodsBetween August 2012 and August 2015, modified PTFE prosthesis rhinoplasty was used to correct low nose and short columella in 52 patients. There were 4 males and 48 females, aged 19 to 45 years (mean, 27 years). Primary rhinoplasty was performed in 47 cases; secondary rhinoplasty was performed in 5 cases, and it was 12-18 months from the first operation (mean, 15 months). During operation, a scaly sag ventral side was made by carving and moving cap shaped nose prosthesis was prepared, and nasal dorsumnasal columella prosthesis covered by tension-free flap was designed. At pre-operation and last follow-up, Image ProPlus 6.0 software was used to measure the nose length, nose depth, nose tip width, nostril/nose tip, nasolabial angle, and nasal tip rotation for evaluation of external nose shape correction; and ultrasound was used to measure the alar cartilage angle, alar two vertex distance, and nose tip to vertex distance for evaluation of internal soft tissue changes; the prosthesis position was observed by CT scan at 12 months. ResultsAll incisions healed by first intention, with no complications. All patients were followed up 7-36 months (mean, 20.4 months). At 12 months after operation, CT scans showed that prosthesis located in the middle of the nose and above nasal bone, septal cartilage and crus mediale cartilaginis alaris majoris in 45 patients; no prosthesis displacement was observed. At last follow-up, image measurement and ultrasound results showed external nose shape parameters (except nostril/nose tip) and internal soft tissue structures were significantly improved when compared with preoperative values (P < 0.05). ConclusionModified PTFE prosthesis rhinoplasty can effectively correct low nose and short columella, with small surgical trauma and good appearance.
ObjectiveTo summarize the research progress of autogenous cartilage scaffold carving method in rhinoplasty.MethodsThe relevant literature about the autogenous cartilage scaffold carving methods in rhinoplasty in resent years at home and abroad was reviewed, and the carving skills, shape, and application scope of different parts of nasal scaffolds were summarized and analyzed.ResultsWillow-leaf shape is still the main method of cartilage scaffold in the back of the nose. However, in nasal reconstruction, it can be carved into an L-shaped scaffold with the nasal columella scaffold through mortise and tenon structure. And it can also crush the autologous cartilage and wrap it with the autologous fascia tissue to form a new nasal dorsal scaffold. The nasal tip scaffold is improved by changing the shape of traditional nasal tip cartilage cap and wrapping with fascia tissue; the nasal alar scaffold has M-shape, q-shape, carving methods; the nasal columella and nasal septum are mostly used “2+2” combined fixed scaffold. The cartilage scaffolds of lateral nose and nasal base are mainly carved in the shape of “八” and crescent.ConclusionAs a rhinoplasty scaffold, there are various carving methods for autogenous cartilage. With the innovation of surgical technique and the improvement of sculpting technique, the effect of autologous cartilage graft in rhinoplasty is getting better and better; meanwhile, tissue engineered cartilage is being applied in rhinoplasty.
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 investigate the influence of buried thread nasal augmentation on dorsal soft tissue of nose and revision rhinoplasty. Methods A clinical data of 29 patients requesting revision rhinoplasty after buried thread nasal augmentation, who were admitted between July 2017 and July 2019 and met the selection criteria, was retrospectively analyzed. All patients were female with an average age of 26.8 years (range, 18-43 years). The patiens were admitted to the hospital at 3-48 months after buried thread nasal augmentation (median, 15 months). Among them, there were 18 cases of insufficient nasal tip projection, 22 cases of insufficient nasal root projection, 7 cases of threads ectasia, 5 cases of threads exposure, 3 cases of infection, and 10 cases with two or more conditions. There were 9 cases of combined short nose deformity, 1 case of spherical hypertrophy of the nasal tip, 3 cases of deviation of the nasal columella, 3 cases of excessive width of the nasal base, and 1 case of nasal hump. Three infected patients only underwent threads removal and debridement. The rest patients underwent revision rhinoplasty, and the dorsum of the nose was made with polytetrafluoroethylene expansion; the tip of the nose was reshaped by taking autologous rib cartilage and alar cartilage in 16 cases, and by taking autologous septal cartilage and alar cartilage in another 10 cases. The threads and surrounding tissue specimens removed during operation were subjected to histologic observation. Nasal length and nasal tip projection were measured after revision rhinoplasty and the ratio was calculated to evaluate the nasal morphology; patient satisfaction was evaluated using the Likert 5-grade scale. ResultsPatients were followed up 12-48 months (mean, 18 months). Inflammation was controlled in 3 patients with infections caused by buried thread nasal augmentation. The remaining 26 patients had satisfactory results immediately after revision rhinoplasty. Before revision rhinoplasty and at 7 days and 6 months after revision rhinoplasty, the nasal length was (4.11±0.34), (4.36±0.25), and (4.33±0.22) cm, respectively; the nasal tip projection was (2.34±0.25), (2.81±0.18), and (2.76±0.15) cm, respectively; and the nasal tip projection/nasal length ratio was 0.57±0.08, 0.65±0.05, and 0.64±0.04, respectively. There were significant differences in the nasal length and the nasal tip projection between time points (P<0.05). There was a significant difference in the nasal tip projection/nasal length ratio between pre- and post-operation (P<0.05), but there was no significant difference between 7 days and 6 months after operation (P>0.05). The Likert score for satisfaction ranged from 1.5 to 5.0 (mean, 4.05). During follow-up period of 26 patients, no nasal prosthesis was exposed, and the shape of the nose was stable, and the nasal skin of 5 patients with exposed threads could be seen with different degrees of scarring; there was no infection, cartilage resorption, and no cartilage deformation, displacement, or exposure. Histological observation showed that absorbable threads were not only absorbed after implantation, but also with the prolongation of time, the inflammatory changes in the surrounding tissues caused by decomposition and absorption of the threads showed a gradual aggravation of the first, the heaviest inflammatory reaction in 6 to 12 months, and then gradually reduce the trend. Conclusion After implantation of the absorbable thread into the subcutaneous tissue of the nasal dorsum, the nature of the thread is different from the body’s own tissue, which will affect the soft tissue compliance of the nasal dorsum. The degradation and absorption of the thread will stimulate the infiltration of inflammatory cells and the proliferation of fibroblasts in the surrounding tissue and then form scar tissue, which will affect the design and effect of revision rhinoplasty.
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.
