ABSTRACT
Objective:To investigate the prevention and treatment for deviation of costal cartilage dorsal onlay grafts in rhinoplasty.Methods:From January 2010 to October 2020, a total of 588 patients (83 male cases, 505 female cases, age range from 25 years to 55 years, 32±4 years in average) accepted costal cartilage rhinoplasty in Shenzhen Mylike Medical Plastic Aesthetic Hospital. During the operation, various methods were used in the process of catilage selection, water bath, sculpture, treatment of nasal dorsal, graft fixation and fascial modification to prevent and treat the deformation and displacement of the costal cartilage dorsal onlay grafts.Results:The immediate postoperative photograph of 588 cases showed that costal cartilage dorsal onlay graft was put on the middle of dorsum. After a follow-up period of 396 cases from 6 to 60 months, the average follow-up period was 12.1 months, there were 44 cases happened with the deviation of dorsal onlay grafts, and deviation was managed after the second rhinoplasty surgery. There was no prolonged function sequela such as ventilation dysfunction, abnormal sensation, or hyposmia occured. 362 cases were satisfied with the aesthetic effect.Conclusions:It is particularly important to grasp the principles of managing costal cartilage in rhinoplasty and to learn how to prevent and treat postoperative complications of costal cartilage dorsal onlay graft.
ABSTRACT
Background: Authors describe their experience with dorsal onlay urethroplasty using Buccal mucosal graft or penile skin graft through dorsal sagittal urethrotomy for bulbar urethral stricture.Methods: From 2014 to 2017, 29 male patients with bulbar urethral stricture have been treated by one stage dorsal onlay substitution urethroplasty using buccal mucosal graft and penile skin graft. Patients with balanitis xerotica obliterans, unhealthy penile skin, oral mucosa pathology or those who had undergone more than one urethral dilation/internal urethrotomy or urethroplasty were excluded from study. Results were analyzed at 6th and 12th month follow up with clinical history and uroflowmetry. Clinical outcome was considered a failure when any postoperative instrumentation was needed, including dilation or optical internal urethrotomy.Results: A total of 16 men age between 21 to 56 years for buccal mucosa graft (BMG) urethroplasty and 13 men age between 18 to 59 years underwent dorsal onlay substitution urethroplasty using BMG and penile skin graft (PSG). Mean stricture length was 4.2 cm (3.8-6) for BMG urethroplasty and 4.1 cm (3.2-5) for PSG urethroplasty. Mean length and width of graft were 4.2 cm and 2.6 cm respectively in BMG urethroplasty while 4.6 cm and 2.5 cm in PSAG urethroplasty. Average follow up months were 13.4 months with overall success rate 87.5% in BMG urethroplasty while average follow up months were 14.6 months with overall success rate 82.3% in PSG urethroplasty.Conclusions: On short term follow up substitution urethroplasty using both penile skin and buccal mucosa graft have comparable results.
ABSTRACT
Background: Urethral stricture is a relatively common disease. The choice of surgery is based on the stricture location, length of the stricture and etiology. Buccal mucosal graft (BMG) urethroplasty with Asopa and Kulkarni techniques, revolutionized the approach to anterior urethral stricture repair. Objective of the study was to compare both the dorsal onlay BMG urethroplasty technique of Kulkarni and the dorsal inlay BMG urethroplasty technique of Asopa for the management of long anterior urethral stricture. Methods: From January 2015 to October 2019, a total of 90 patients with long anterior urethral strictures were randomized into two groups. Group A (42 patients) managed by Kulkarni technique. Group B (48 patients) managed by Asopa technique. BMG urethroplasty was considered successful if no further procedure required postoperatively with maximum flow rate >15 ml/s during the follow-up period.Results: The success rate in group A and B were 80.9% and 87.5%, respectively. The mean operative time was significantly longer in group A (175±22.6 min) than in group B (102±18.14 min, p-value <0.001). The average blood loss was significantly higher in group A (154±15.65 ml) than in group B (112.76±12.62 ml, p-value <0.012).Conclusions: The dorsal onlay technique of Kulkarni and the dorsal inlay technique of Asopa buccal mucosal graft urethroplasty are reliable and satisfactory procedures with good success rates and minimum complications.
ABSTRACT
Background: Anterior urethral stricture involves penile, bulbar or panurethra with varied aetiology. Direct vision internal urethrotomy (DVIU), stricture excision with primary end to end anastomosis, single stage or staged reconstruction with local flap or buccal mucosal graft (BMG) are surgical options.Methods: This single centre retrospective study was conducted from April 2017 to March 2019. Patient underwent DVIU, stricture excision with primary end to end anastomotic, staged urethroplasty, BMG urethroplasty (BMGU) dorsal inlay Asopa technique, dorsal onlay Kulkarni technique and ventral onlay technique depending on site and extent of strictures. Preoperative, intraoperative, post-operative data were reviewed.Results: Here, 51 patients underwent DVIU for single soft short segment bulbar urethral stricture with success rate 58.82%. 26 patients with post traumatic short segment bulbar urethral stricture underwent excision and primary end to end anastomosis with success rate 92.31%. Patients with long segment bulbar urethral stricture underwent either dorsal onlay (n=19) or ventral onlay (n=14) BMGU with success rate 89.47% and 85.71% respectively. Total 59 patients with long segment penile or pan urethral stricture underwent either single stage (n=27) or staged reconstruction (n=32) with success rate of 85.18% and 90.63% respectively. Patients with staged reconstruction had significantly longer hospital stay (p<0.0001) and poor quality of life due to laid opened urethra. Asopa’s dorsal inlay (n=15) and Kulkarni’s dorsal onlay (n=12) BMGU had equivalent success rate of 86.67% and 83.33% and comparable complications.Conclusions: Surgery for urethral stricture differs according to site and extent of stricture. Single stage BMG urethroplasty is preferred modality for long segment bulbar, penile and panurethral stricture.
ABSTRACT
Urethral stricture is a common disease with changing etiology and changing practices in management. Management options were grossly determined by cause, site, length of stricture and also by other factors like prior attempts of repair and local genital skin condition. Treatment options vary from dilatation, optical urethrotomy to various types of urethroplasty. Substitution urtethroplasty is done using various types of graft materials like skin, buccal mucosa, bladder mucosa or colonic mucosa. Over the past 10-15 years buccal mucosa grafts have been increasingly used in the urethral reconstruction. Barbagli technique (Dorsal onlay technique) has the advantages of no sacculation which is seen with ventral onlay grafts, good neovascularity and less shrinkage (10%) rate. We have presented the results and complications of doral onlay buccal mucosa graft urethroplasty (Barbagli technique) in 20 cases performed over a period of 30 months in our institution. Our study showed a success rate of 80% at the end of 2yrs follow up, comparable with other studies, with a restructure rate of 20%. None of our patients developed urethrocutaneous fistula and urethral diverticulum.
