Long-Term Surgical Outcomes of Primary Rhinoplasty.

To examine the impact of primary rhinoplasty on subsequent rhinoplasties for patients with cleft lip nasal deformity. Retrospective cohort study. Tertiary care pediatric hospital. Individuals who underwent definitive cleft lip repair at our institution from 2000 to 2006 with a current age of 18 or older. Number and timing of subsequent rhinoplasties. Among 199 individuals, 94 (47.2%) underwent primary rhinoplasty. Follow-up was 15.0 ± 4.8 years in the PR cohort and 15.0 ± 5.1 years in the NPR cohort (p = 0.993). In bilateral cleft lip, interdomal suture predicted fewer subsequent rhinoplasties (β=-0.310, p = 0.033), while history of primary rhinoplasty predicted greater age at subsequent rhinoplasty (β=1.800, p = 0.040). Among individuals with follow-up beyond age 18, intranasal stenting predicted fewer subsequent rhinoplasties (β=-0.609, p = 0.015). Most underwent subsequent nasal correction aside from 7 (19.4%) and 9 (20.9%) in the PR and NPR cohorts, respectively (p = 0.536). There was no difference in mean subsequent rhinoplasties between cohorts (1.1 ± 0.8 versus 1.3 ± 1.1, p = 0.284). Individuals with complete cleft lip underwent more lifetime rhinoplasties (1.9 ± 1.0 versus 1.2 ± 1.2, p = 0.007). Primary rhinoplasty with interdomal tip sutures in bilateral cleft lip was associated with fewer subsequent rhinoplasties. Primary rhinoplasty may delay subsequent nasal correction, though most who underwent primary rhinoplasty ultimately required nasal correction later in childhood. Postoperative nasal stenting may provide longer-term nasal benefits and should be considered at time of definitive cleft lip repair.

Retrospective Evaluation of a Novel Nasal Tip Suture Technique.

Nasal tip surgery is a crucial aspect of rhinoplasty in which suture techniques play a significant role. Early suturing techniques focused primarily on repositioning alar cartilage remnants after they had undergone significant resection. The size, contour, and orientation of the medial and lateral crura are primary factors in creating a tip shape. In this review, we retrospectively evaluated obliquely oriented dome sutures with triangular dome resection that was performed in 540 rhinoplasty cases at Yunus Emre Hospital between 2015 and 2020. Dome-defining sutures were placed, and a triangular cartilage resection was performed. Subsequently, oblique sutures were placed to achieve the desired lateral cartilage position. Objective assessment of postoperative results (Objective Rhinoplasty Outcome Score), patient satisfaction assessments, and nasal examinations were conducted. The objective assessments of the esthetic results showed a significant improvement, with a mean score of 3.6, which represents a good to excellent outcome. Most patients were subjectively satisfied with the surgical outcomes of rhinoplasty. No serious complications, such as infection, recurrence of deviation, nasal obstruction, or esthetic problems such as dorsal irregularities, were observed after surgery. Overall, suturing techniques play an important role in determining the nasal tip shape. Our technique is beneficial for maintaining a favorable lateral crural position, leading to improved patient satisfaction.

Development and Evaluation of a High-Fidelity Rhinoplasty Simulator.

Rhinoplasty is a challenging procedure with a steep learning curve. Surgical simulators provide a safe platform to gain hands-on experience without compromising patient outcomes. Therefore, rhinoplasty is an ideal procedure to benefit from an effective surgical simulator. A high-fidelity rhinoplasty simulator was developed using three-dimensional computer modeling, three-dimensional printing, and polymer techniques. The simulator was tested by six surgeons with experience in rhinoplasty to assess realism, anatomic accuracy, and value as a training tool. The surgeons performed common rhinoplasty techniques and were provided a Likert-type questionnaire assessing the anatomic features of the simulator. A variety of surgical techniques were performed successfully using the simulator, including open and closed approaches. Bony techniques performed included endonasal osteotomies and rasping. Submucous resection with harvest of septal cartilage, cephalic trim, and tip suturing, as well as grafting techniques including alar rim, columellar strut, spreader, and shield grafts, were performed successfully. Overall, there was agreement on the simulator's anatomic accuracy of bony and soft-tissue features. There was strong agreement on the simulator's overall realism and value as a training tool. The simulator provides a high-fidelity, comprehensive training platform to learn rhinoplasty techniques to augment real operating experience without compromising patient outcomes.

Exploring the Resurgence of the Preservation Rhinoplasty: A Systematic Literature Review.

The underlying principles of preservation rhinoplasty (PR) center around maintaining the soft tissue envelope, dorsum, and alar cartilage through surgical manipulations and tip suture techniques. In particular, the let-down (LD) and push-down (PD) techniques have been described, although reports of indications and outcomes in the literature are sparse. A systematic review of the literature was performed using search terms "preservation" OR "let down" OR "push down" AND "rhinoplasty" on PubMed, Cochrane, SCOPUS, and EMBASE databases. Patient demographic information, operative details, and surgical outcomes were recorded. Sub-cohorts for patients who underwent LD and PD techniques were analyzed utilizing Fischer's exact test for categorical variables and Student's t test for continuous variables. Overall, there were 5967 PR patients in 30 studies in the final analysis, with 307 patients in the PD cohort and 529 patients in the LD cohort. The Rhinoplasty Outcome Evaluation Questionnaire showed a significant increase of patient satisfaction after PR compared to before PR (62.13 vs 91.14; p < 0.001). There was a significantly lower rate of residual dorsal hump or recurrence of 1.3% (n = 4) in the PD when compared to 4.6% (n = 23) in LD cohorts (p = 0.02). The revision rate of PD (0%, n = 0) was also significantly lower than that of LD (5.0%, n = 25) (p < 0.001). Based on these published articles, it seems that preservation rhinoplasty is safe and efficacious procedure with improved dorsal aesthetic lines, reduced dorsal contour irregularities, and claimed excellent patient satisfaction. In particular, the PD technique has fewer reported complications and revisions than LD approach, although PD is often indicated in patients with smaller dorsal humps.

A Longitudinal Study of Improvement in Nasal Airway Obstruction after Secondary Cleft Rhinoplasty.

Nasal airway obstruction is an increasingly recognized phenomenon in patients with cleft lip and/or palate and has the potential to significantly affect quality of life in this patient population. To date, the effect of secondary cleft rhinoplasty on cleft-related nasal airway obstruction has not been studied. Patients undergoing secondary cleft rhinoplasty at the Children's Hospital of Philadelphia from 2015 to 2021 were identified. Preoperative and postoperative Nasal Obstruction Symptom Evaluation scores were recorded. Alterations in scores were evaluated for variation depending on patient characteristics, operative maneuvers, and postoperative nasal stenting. Nasal airway obstruction was present in mild to moderate severity in patients before secondary cleft rhinoplasty. Postoperatively, obstruction improved or resolved in the domains of nasal blockage/obstruction, trouble breathing through the nose, and ability to get enough air through the nose during exertion (P < 0.05). Overall composite Nasal Obstruction Symptom Evaluation scores improved (P < 0.05). Lateral crural strut grafting was associated with improvement in nasal blockage, whereas alar revision and tip sutures were associated with worsening in specific nasal symptoms. Patients who underwent nasal stenting were found to report less trouble breathing after surgery than patients who did not (P < 0.05). Nasal airway obstruction is present in mild to moderate severity in patients with cleft lip and/or palate, and the subjective severity of obstruction is decreased by secondary cleft rhinoplasty. Specific operative maneuvers are associated with alterations in nasal airway obstructive symptoms, and nasal stenting is associated with an improvement in trouble breathing after secondary cleft rhinoplasty.

Open Rhinoplasty for Nasal Tip Correction by the Transverse Columellar Incision for Egyptian &amp; Mediterranean Noses

Rhinoplasty may be the most common, most challenging, most unforgiving in plastic surgery. It is an ultimate combination of an evolving art and science. Rhinoplasty is a precise surgery in which the margin of error is measured in millimeters. Excellent results can only be obtained by a thorough knowledge of nasal anatomy and the surgical relevance of the alteration of the anatomic structures. To a lot of the Junior Staff, Rhinoplasty is a blind procedure requiring much imagination. This procedure has always been a challenge to the plastic surgeons. Objectives: Since the early eighties I had all the worry a young plastic surgeon has: standardizing his results for Aesthetic Rhinoplasty. Results were not always what one expected, and definitely tip correction was a great challenge. It was then I embarked adopting the open Columellar Incision. I am sharing with you my journey over 40 years and the results of believing and mastering a technique, preaching it in different arenas, and the final results achieved d not only nationally or regionally but also internationally when this technique is now universally accepted as a precise tool for better refinement. The indications limitations and the ghost of the scar are shown and proved to be over stated. In the millennium different strategies (suturing and grafting) have been adopted to obtain better aesthetic outcome and less functional disturbances, all these seem to go hand in had with the open rhinoplasty incision. Different indications are briefly gone through in this review and the long-lasting results are shown. Conclusions: Excellent symmetry, Lack of supratip deformity, particularly in Secondary and Tertiary Rhinoplasty The scar was inconspicuous in the healing phase, then in a few months it tended to migrate lower down and becomes almost invisible. The use of either grafts or various tip sutures can help in the control of the tip dynamics. The aesthetic outcome following a combination of suturing and grafting was more satisfactory than the outcome that can be achieved following either one of them. All these techniques could not be achieved through a closed endonasal rhinoplasty

Nasal Tip Shaping Finesse in Rhinoplasty.

Anatomic subtleties of the nasal tip have a dramatic impact on the overall appearance of the nose. Mastery of normal nasal aesthetics and anatomy is a critical prerequisite to adeptly performing nasal tip refinement during open rhinoplasty. This article and series of videos aim to provide a focused review of nasal tip analysis, anatomy, and surgical technique, with particular emphasis on pertinent tip sutures and cartilage grafts.

Correction of Severe Secondary Cleft Lip Nasal Deformity.

The lower lateral cartilages (LLCs) are key elements for alar and tip support. Repositioning of both LLCs is an effective procedure for correcting a laterally spreading dome of LLCs and drooping nasal tip in cleft lip nasal deformity (CLND). The alar contour graft has become an essential component of rhinoplasty for correcting the concave or collapsed and retracted alar. Herein, onlay cartilage graft was combined with nasal tip plasty to correct hypoplastic cleft lateral crus or alar rim retraction, and with columella strut to obtain better aesthetic outcomes in patients with severe CLND. Seven patients with severe secondary unilateral CLND, including hypoplastic cleft lateral crus or alar rim retraction, underwent rhinoplasty from October 2013 to April 2020. Both LLCs were isolated and repositioned approximated medially using tip suture technique combined with columella strut. A septal cartilage onlay graft was applied on the hypoplastic cleft lateral crus. Cartilage graft on the nasal tip was performed to further project and enhance the nasal tip. Photogrammetric evaluation of the operated patients and statistical analysis of the obtained data were performed. The average age at operation was 23.5 (range: 17-36) years. The follow-up period was 6-36 (mean, 14.3) months. All patients were enrolled by photogrammetric evaluation. Height of the medial nostril and short axis of the nostril on the cleft side were increased with a statistical significance of P < 0.05, indicating that depressed ala on the cleft side, which is a feature of CLND, was corrected similar to that of the noncleft side. The alar contour cartilage graft, as an effective adjunctive technique, improves the alar margin, prevents the alar rim from collapsing, and provides supports to the cleft-side alar rim. It can be a prophylactic measure to prevent postoperative retraction in patients with weakened LLCs. Lower lateral cartilage repositioning, columellar strut, and nasal tip plasty are useful for correcting severe secondary unilateral CLND.

Role of cartilage correcting sutures in single-stage secondary rhinoplasty for unilateral cleft lip nose deformity.

Introduction:The purpose of this study is to highlight the role of cartilage correcting suture in single-stage surgical correction for secondary unilateral cleft lip nose deformity with three-dimensional observations of preoperative and postoperative nasal forms.Material and Methods:Between July 2017 and June 2019, 18 consecutive patients of unilateral cleft lip nose deformity aged between 16 and 28 years underwent surgical correction. The corrective procedure of nose involved columellar lengthening, medial and lateral nasal osteotomies along with augmentation of premaxilla by bone graft at premaxilla, and alar base wedge resections. Focus was laid to correct nasal cartilaginous framework using tip sutures along with repositioning of lower lateral cartilages, fixation of the alar cartilage complex to the septum, and the upper lateral cartilages. We investigated the following surgical interventions and nasal tip suture techniques, which were transdomal suture, interdomal suture, lateral crural mattress suture, columella septal suture, and intercrural suture.Results:We achieved adequate esthetic and functional results in all the patients without any morbidity.Conclusion:This concept of simultaneous approach toward complete single-stage correction of secondary cleft lip nasal deformity incorporating various cartilage suture using 5-0 nylon in developing nation like ours, where the patient presents late with complex conditions showed promising esthetic and functional outcome.

Correction of secondary unilateral cleft lip nasal deformity in adults using lower lateral cartilage repositioning, columellar strut, and onlay cartilage graft on the nasal tip with open rhinoplasty combined with reverse-U incision

A rhinoplasty technique involving lower lateral cartilage (LLC) repositioning and grafting of ear cartilage allows for nasal lengthening and nasal tip mobility. For better esthetic outcomes in patients with cleft lip nasal deformity (CLND), we combined cosmetic nasal tip plasty with standard techniques. We performed open rhinoplasty combined with reverse-U incision and V-Y plasty in 62 patients with secondary unilateral CLND from October 2013 to June 2018. Both LLCs were isolated, repositioned, approximated medially, and advanced with a Medpor strut, followed by tip suture technique. To further project and enhance the nasal tip and columella, application of ear cartilage onlay graft was used. As adjunctive procedures, septoplasty or osteotomy was carried out for correction of septal or nasal bone deviations, respectively. Photogrammetric evaluations of patients and statistical analyses were performed. Average age at operation was 23.5 years (range: 18-42 years). Of the 62 patients, 15 underwent dorsal augmentation with silicone implant. Two-layer conchal cartilage onlay grafting was performed to manage tip height. Outcomes in 34 patients were analyzed with pre- and postoperative photography. Nasal tip projection increased, alar base width index decreased, and alar and columellar symmetry significantly improved. No Medpor implant exposure or other adverse outcomes occurred. The proposed technique is effective for correcting secondary unilateral CLND and achieving a satisfying nasal appearance in adults.

Open Rhinoplasty

Rhinoplasty is often considered the black box of plastic surgery. This apprehension can be overcome by having a fine-tuned understanding of nasal anatomy, developing an appreciation for nasal aesthetics, and becoming well-versed in the array of surgical techniques available to address specific cosmetic and functional concerns. Technical care and finesse are required in this type of surgery, where even 1 mm of change can result in a profound difference. Nasal function must also be assessed and preserved during rhinoplasty. Aside from these technical points, it is equally important to accurately and thoroughly understand each patient’s goals and to communicate the realistic outcomes and limitations of what can be done through surgery. Key words: open rhinoplasty, nasal anatomy, nasofacial analysis, rhinoplasty techniques, rhinoplasty preoperative evaluation, rhinoplasty postoperative management, lateral nasal osteotomies, nasal tip grafts, nasal tip suture techniques This review contains 23 figures, 2 tables, and 43 references.

Endoscopic "Quick" Septoplasty in Preservation Rhinoplasty.

Preservation rhinoplasty (PR) is revolutionizing rhinoplasty surgery, based on new anatomical studies, advanced tip suture techniques, and refinement of surgical techniques. Septal surgery is a fundamental preparatory stage during PR, especially for the dorsal preservation let/push-down procedure. To increase the predictability of the septoplasty aesthetic effects on the nasal dorsum and further extend the principles of PR to septal surgery, we applied the endoscopic technology to the "quick" septoplasty technique we had already developed in the past decades. One hundred sixty-six patients (41 males, 125 females; mean age, 39.7 years; age range, 18-61 years) were submitted to endoscopic "quick" septoplasty for septal deviation during PR procedure. Preoperative evaluation of the nasal dorsum included external examinations of the size, shape, and orientation of the dorsum. Anterior active rhinomanometry was performed in all patients to determine nasal flow resistance preoperatively and 6 months after surgery. Preoperative and postoperative patients' scores on the Nasal Obstruction Septoplasty Effectiveness questionnaire were compared to assess the improvement of nasal symptoms after surgery. The duration of the septoplasty procedure was measured for all the patients. Standard nasal photographic assessment was performed before and 6 months after surgery. Postoperatively, 98.8% of our patients displayed an improvement of their nasal breathing function. No complication in terms of septal perforation, nasal infection, or bleeding was noticed. No case of turbinoseptal synechiae or cerebrospinal fluid leak was recorded. The dorsum preservation rhinoplasty procedure was successfully completed in all patients. The mean septoplasty operative time, excluding local anesthesia injection and other surgical procedures associated with septal surgery such as turbinoplasty and rhinoplasty, was 11.41 ± 6.23 minutes (range, 9-31 minutes). Our results show that a short surgical time is needed to perform the proposed endoscopic septoplasty procedure. Such a short operative time allows the physician to both correct septal deviations quickly and correct/reduce the cartilaginous hump, thus representing a fundamental element of PR. In addition, the minimal tissue dissection reduces intraoperative nasal edema, favoring intraoperative aesthetic evaluation.

Lateral pharyngoplasty techniques for obstructive sleep apnea syndrome: a comparative experimental stress test of two different techniques.

To show the different effects of expansion sphincter pharyngoplasty (ESP) and barbed reposition pharyngoplasty (BRP) on muscle tension and muscle fiber tearing using a comparative experimental stress test with a frog thigh muscle model. Frog thigh muscle was used for this experimental study. A Barbed suture was used to simulate the BRP pharyngoplasty whereas a Vicryl 3-0 suture was used to simulate the ESP technique. The other extremity of the suture was attached to traction scales. The traction scales were used to measure the weight relative to the amount of force required to obtain muscle breaking. Both surgical techniques were simulated on the frog muscle. Traction was performed until muscle breaking was observed, measuring the value of force needed to obtain muscle rupture. Specimen muscle breakdown in the ESP simulation occurred with an average value of 0.7kg of traction force. Contrarily, specimen muscle breakdown in the BRP simulation with Barbed suture occurred with an average value of 1.5kg of traction force CONCLUSION: During simulation of the ESP technique, specimen muscle breakdown occurred with an average value of traction force lower than in the BRP technique. During traction the multiple lateral sustaining suture loops of BRP could ensure greater stability then the single pulling tip suture of ESP with minor risk of muscle fiber damage.

A novel tip suture technique in rhinoplasty: lateral crus caudocephalic rotation suture

Rhinoplasty is often performed to narrow the nasal tip. Compared with extensive cartilage excision, scoring, and transaction, suture techniques are a favorable method. Suturing techniques offer favorable esthetic and functional outcomes. However, deformities and unnatural appearances may occur if sutures are overtightened or placed incorrectly, and it is possible to inadvertently narrow the external nasal valve and invert the caudal sides of the lateral crura. In this retrospective study, author analyzed the functional and esthetic outcomes of a novel suture method developed to support the external nasal valve by caudocephalic rotation of the lateral crura. The outcomes of the lateral crus caudocephalic rotation suture (CC suture) method were assessed in 24 patients (22 females, two males; age 18–43 years) who underwent primary septorhinoplasty and had iatrogenic or genetic inversion of the caudal sides of the lateral crura. The patients were followed up for 12–36 months. During this time, no serious complications were noted in any patient, and there was no requirement for revision surgery. Satisfactory or acceptable results were obtained in all patients. The CC suture technique is a simple, reversible, and nondestructive technique that benefits from minimal graft use, decreased operation time, improved function and cosmesis, and a short learning curve. Level of evidence: Level V, therapeutic study.

Reevaluating the Current Model of Rhinoplasty Training and Future Directions: A Role for Focused, Maneuver-Specific Simulation.

Rhinoplasty is known for its complexity in planning and execution. For trainees, knowledge acquisition is often adequately attained. The mastery of skills, however, occurs by means of hands-on exposure, which continues to be a challenge. This article discusses the positive progress made in rhinoplasty training, and objectively demonstrates a need for more hands-on rhinoplasty exposure for residents. A systematic review was performed in adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Concurrently, an online survey was developed, assessing resident comfort and training in rhinoplasty, and e-mailed to Canadian and U.S. plastic surgery training programs. ONE HUNDRED THIRTY-EIGHT: residents completed the survey, 62 junior (first- to third-year residents) and 76 senior residents (fourth- to sixth-year residents). Seventy-two percent of senior residents (95 percent of sixth-year residents) reported adequate rhinoplasty exposure, as opposed to 13 percent of junior residents. Seventy-five percent of senior residents most often participated as observers or first assistants, 25 percent participated as co-surgeons, and 73.9 percent did not perform a key rhinoplasty step more than five times. Residents felt the three most difficult steps of rhinoplasty were nasal osteotomy (76.1 percent), caudal septum/anterior nasal spine manipulation (65.2 percent), and nasal tip sutures (55.8 percent), and 73.9 percent felt that simulator training would substantially improve confidence. Despite sufficient exposure to rhinoplasties, residents were least confident in performing rhinoplasties relative to other aesthetic procedures, likely because of the high proportion of rhinoplasty exposure that is observational as opposed to hands-on acquisition of surgical maneuvers in the operating room. The survey established the maneuvers residents find the most difficult, and as programs adopt competency-based training, developing rhinoplasty simulators targeting specific identified steps may help improve competence for rhinoplasty skills.

Reading man flap for repair of soft tissue defects in distal fingers

Objective To explore the Reading man flap for the treatment of soft tissue defects in distal fingers. Methods From May, 2014 to June, 2017, Reading man flaps were transferred in the emergency room to repair soft tissue defects in distal fingers in 46 patients. There were 28 cases of finger pulp defects, 6 cases of dorsal defects and 12 cases of finger stump defects with the size of soft tissue defects ranged from 1.0 cm×0.9 cm to 2.2 cm×2.0 cm (average, 1.2 cm×1.3 cm). The volar, dorsal and hybrid flaps were 28, 6 and 12 cases respectively. The average size of the major flap and minor flap were 1.8 cm×1.2 cm and 1.4 cm×0.8 cm, respectively. All donor sites were sutured directly. All patients were followed-up by review in the outpatient department. Results The consumed operative time was 35-48 min, with an average of 37.8 min. Prophylactic antibiotics and wound dressing were conducted postoperatively. The tip of the minor flaps occurred inflammation and small blister in 2 cases and eased by removal of the tip sutures. Traumatic neuralgia occurred in 1 case and self-healed after 3 months. Twenty-six cases were followed-up at least 11 months, which were 16 cases of finger pulp defects, 3 of dorsal defects and 7 of finger stump defects. On an average of 10.5 (9-27) months followed-up, all flaps survived. Except 4 cases with slim hook nail deformity, the remaining flaps were observed with satisfactory texture and appearance, the bulky deformity and scar contracture did not occur. Two points distinguishment on the major and minor flaps were 3.3-6.2 (average, 4.5) mm and 5.5-9.8 (average, 7.1) mm respectively. According to the Trial Standard for Evaluation of Upper Limb Function of Chinese Society of Hand Surgery, it was excellent in 28 cases, good in 11 cases and moderate in 7 cases, with the overall excellent and good rate of 84.8%. Conclusion The Reading man flap is a good option for treatment of the small size soft tissu defect in distal fingers with the advantages of simple procedure, high success rate, good appearance and sensory recovery.

Nasal Tip Grafts.

The nasal tip is the most prominent part of the nose. The aim of this paper is to review nasal tip grafts with detailed explanation and figures. The authors searched PubMed, Google, Google Scholar, and Proquest Central database of the Kirikkale University. Search was performed with the key words of "nasal," "tip," "graft." The indications and grafting techniques were presented. The external shape of the nasal tip is determined by the curves and contours of the lower lateral cartilages and their interactions with the surrounding tissues. Normative data exist regarding the ideal shape and shadowing of the nasal tip. The mainly used tip grafts in rhinoplasty are "Floating graft (Goldman) ," "Tip Onlay Graft," "Columellar Strut Graft," "Caudal Septal Extension Graft," "Shield Graft," "Alar batten onlay graft," "Lateral Crural Strut Grafts," "Alar rim grafts." When tip sutures are not enough, cartilage tip grafts offer a versitile and effective way to change the nasal tip. While there has been a vast array of grafting techniques described, this paper reviewed many of the most popular and useful grafts in modern use.

The Nasal Ligaments and Tip Support in Rhinoplasty: An Anatomical Study.

In 1971, Janeke and Wright1 published a now classic study on the support of the nasal tip in which they found four areas of anatomic support. These findings led to the "tripod concept" of tip support. Recently, surgeons have begun repairing and/or preserving the nasal ligaments as a method to control tip projection and rotation. Therefore, a reassessment of the nasal ligaments and tip support is warranted. The present study was done to investigate the ligamentous and structural support of the nasal tip. Clinically, surgeons are aware of the role of the nasal ligaments and are beginning to utilize tip suture techniques to achieve greater tip refinement and long-term support. Anatomic studies were conducted on 24 fresh cadavers at the time of autopsy. The two groups consisted of the following: (1) group 1 included dissection of 10 cadavers concentrated on the various ligaments of the nose; and (2) group 2 involved dissections of 14 cadavers analyzing the relationship between the alar domes and the anterior septal angle (ASA). Regarding the ligaments of the nose, we were able to consistently identify the following ligaments: (1) interdomal; (2) intercrural; (3) Pitanguy's midline; (4) pyriform; and (5) a scroll ligament complex consisting of the longitudinal and vertical scroll ligaments. We did not find two commonly accepted ligaments: (1) a "footplate ligament" from the footplate of the medial crus to the caudal septum; and (2) a "sesamoid ligament" attachment from the accessory cartilage to the pyriform aperture. Dissections done to study the relationship between the domes and ASA revealed that the domes projected an average of 5.7 mm (range, 2.2-9.6 mm) above the ASA and were longitudinally 5.5 mm (range, 2.9-9.5 mm) caudal to the ASA. Thus, there was no direct support from the ASA to the domes. It is our recommendation that surgeons should consider preservation of the nasal ligaments whenever possible and utilize them to manipulate tip projection, position, and rotation. Awareness of the relationship between the dome and the caudal septum will hopefully minimize problems with the tongue-in-groove operation.

Catheter Fixation Behind the Urachus: A Novel Laparoscopic Technique to Revise Malfunctioning Peritoneal Dialysis Catheters

Peritoneal dialysis is one of the types of renal replacement therapy which is commonly used in patients with the end-stage renal disease. The cost-effectiveness and easy usage are the advantages of peritoneal dialysis. However, peritoneal dialysis is not always free of a problem and among all of its complications, catheter tip migration and omental wrapping are more common as are considered as the causes of catheter malfunctioning. Different techniques are used to correct the malfunctioning catheters such as manipulator techniques, laparoscopic repositioning with tip suturing, omentectomy and omentopexy. In this article, we are proposing two cases, which had been referred by peritoneal catheter malfunctioning and then received a new method of surgery successfully and didn’t have any complications after 36 months follow up. This method could simplify the procedure of operation and urachus ligament and reduce time and cost of the process.

Evidence-Based Medicine: Current Practices in Rhinoplasty.

After studying this article, the participant should be able to: 1. Perform aesthetic and functional nasal analysis to guide septorhinoplasty. 2. Recognize common complications associated with rhinoplasty. 3. Select appropriate septorhinoplasty techniques to refine nasal aesthetics and treat nasal airway obstruction. 4. Identify factors leading to poor patient satisfaction following rhinoplasty. Septorhinoplasty is among the most technically challenging procedures in the realm of plastic and reconstructive surgery. Moreover, it is a constantly evolving topic with extensive background literature. Surgeons must be comfortable with the traditional knowledge base and the current practices in the field. This article reviews the latest thinking on patient selection, functional indications, aesthetic analysis, and operative techniques in septorhinoplasty, with an emphasis on key cartilage grafting and tip suture techniques.
