In 48 patients with maxillonasal dysplasia the retruded nasal base was corrected with onlay cancellous bone grafts after subperiosteal dissection using an oral vestibular approach. Support for the nasal dorsum was achieved in 39 patients with an L-shaped bone graft from the iliac crest introduced through the same approach. The advancement of the nose was found stable on lateral cephalograms; i.e., resorption did not occur. However, the grafts showed considerable remodeling. Half the patients found the stiffness of the nose to be disturbing. In nine patients, the cartilaginous septum was used instead as a support for the nasal dorsum and tip. At operation, the entire cartilaginous septum was mobilized after subperichondrial dissection and rotated forward either pedicled at the nasal dorsum or completely released. Cartilage regenerated in the periochondrial pocket left behind the advanced septum. The anterior transfer of the nose was 6 to 10 mm. The use of septal advancement is preferred over bone implants in the correction of maxillonasal dysplasia in patients in whom the bony nasal dorsum is of adequate height because it results in a soft and flexible nose and the risk of traumatic fracture and resorption is eliminated. The technique has been used in adolescents with promising results.  相似文献

An algorithm for correcting the asymmetrical nose   总被引:3,自引:0,他引:3  
Correction of the twisted nose forms the watershed of aesthetic and reconstructive rhinoplasty, combining and requiring elements of each. Faced with this formidable task, surgeons have fashioned a great number of techniques, many of which rely for their cardinal step on cutting, fracturing, or scoring the dorsal septal strut. While highly satisfactory results have been achieved with these methods, the constant problem of loss of dorsal support remains. It is possible in many cases to align the crooked nose while leaving intact osteocartilaginous dorsal support. The key determination to be made is the preoperative aesthetic balance, itself a product of bridge height and nasal base size. Once nasal aesthetics have been established, the algorithm proceeds as follows: First, resect the dorsum in the area of the deviation until the dorsal septal edge is sufficiently close to the midline to allow camouflage of the remaining asymmetry. Second, perform the septal resection necessary for the airway, preserving a continuous dorsal strut. Third, augment according to (a) the support needed for the dorsum, middle vault, columella, and tip and (b) the aesthetic balance that must be restored.  相似文献

Reconstruction based on the aesthetic subunit principle has yielded good aesthetic outcomes in patients with moderate to severe nasal defects caused by trauma or tumor resection. However, the topographic subunits previously proposed are often unsuitable for Orientals. Compared with the nose in white patients, the nose in Orientals is low, lacks nasal muscle, and has a flat glabella; the structural features of the underlying cartilage and bone are not distinctly reflected in outward appearance. The authors devised aesthetic subunits suitable for Orientals, and they used these units to reconstruct various parts of the nose. The major difference between these units and those presented previously is the lack of soft triangles and the addition of the glabella as an independent unit. The authors divided the nose into the following five topographic units: the glabella, the nasal dorsum, the nasal tip, and the two alae. The border of the nasal dorsum unit was extended to above the maxillonasal suture. The basic reconstruction techniques use a V-Y advancement flap from the forehead to reconstruct the glabella, an island flap from the forehead to reconstruct the nasal dorsum and nasal tip, a nasolabial flap to reconstruct an ala, and a malar flap to reconstruct the cheek. A combination of flaps was used when the defect involved more than one unit. This concept was used for nasal reconstruction in 24 patients. In one patient undergoing reconstruction of the nasal dorsum and in one undergoing reconstruction of the nasal tip, the texture of the forearm flap did not match well, which resulted in a slightly unsatisfactory aesthetic outcome. In one patient in whom the glabella, nasal dorsum, and part of the cheek were reconstructed simultaneously, a web was formed at the medial ocular angle, and a secondary operation was subsequently performed using Z-plasty. In one patient undergoing reconstruction with a forehead flap, defatting was required to reduce the bulk of the subcutaneous flap pedicle at the glabella. However, suture lines were placed in the most inconspicuous sites in all patients, and the use of a trapdoor contraction emphasized the three-dimensional appearance of the nose. The use of these aesthetic subunits for reconstruction offers several advantages, particularly in Oriental patients. Because the nasal dorsum is reconstructed together with the side walls, tenting of the nasal dorsum is avoided, which prevents a flat appearance of the nose. A forehead flap is useful in the repair of complex defects. Defects of the alae should be separately reconstructed with a nasolabial flap to enhance the effect of the trapdoor contraction and to highlight the three-dimensional appearance of the nose. Candidates for reconstruction should be selected on the basis of nasal structure. The results suggest that these units can also be used in some white patients.  相似文献

Septal deviations interfere with nasal airflow and contribute to deformities in the external appearance of the nose. An aesthetically and functionally satisfactory correction of severe septal deformities or "crippled" septal plates often requires a temporary intraoperative removal of the septal cartilage for appropriate remodeling. This article describes refinements to the previously described technique of extracorporal septoplasty; these refinements have proven useful and have made the procedure safer in the hands of less experienced surgeons. The refinements simplify the straightening methods for the explanted septal plate, achieving a stable and median fixation of the replanted septum while maintaining a satisfactory contour of the nasal dorsum. A milling cutter is used to straighten the irregularities of the explanted septal plate and to thin broadly based anterior nasal spines. When necessary, microplates are added to stabilize the osteotomized and medialized anterior nasal spine. The final positioning of the replanted septal plate is greatly enhanced by a rein stitch, transosseous sutures, and multiple quilt stitches. Additionally, direct fixation of the replanted septum to the edges of the upper lateral cartilages further improves the stability of the reconstruction. Finally, particular care should be taken to avoid residual irregularities of the nasal dorsum; it they occur, these irregularities can be covered with a thin cartilaginous splint or a layer of dehydrated fascia lata or autologous temporal fascia. A total of 436 patients who underwent rhinoseptoplasties at the authors' department during a 1-year period were reviewed. Of these patients, 108 presented with severe septal deviations and underwent an extracorporal septoplasty using the refined techniques described herein. Despite the complexity of the procedure, the patients' satisfaction rates were high, independent of the operating surgeon.  相似文献

The deviated nose represents a complex cosmetic and functional problem. Septal surgery plays a central role in the successful management of the externally deviated nose. This study included 260 patients seeking rhinoplasty to correct external nasal deviations; 75 percent of them had various degrees of nasal obstruction. Septal surgery was necessary in 232 patients (89 percent), not only to improve breathing but also to achieve a straight, symmetrical, external nose as well. A graduated surgical approach was adopted to allow correction of the dorsal and caudal deviations of the nasal septum without weakening its structural support to the dorsum or nasal tip. The approach depended on full mobilization of deviated cartilage, followed by straightening of the cartilage and its fixation in the corrected position by using bony splinting grafts through an external rhinoplasty approach.  相似文献

Whereas reconstruction of the hypoplastic nose with rib grafting is common, the long-term outcomes of nasal growth and aesthetics are unknown. This study assessed nasal morphometrics, patient satisfaction, and the perception of nasal appearance by others up to 15 years after nasal reconstruction using cantilevered autogenous chondro-osseous rib grafting with rigid internal fixation in children. Records of all patients who received nasal rib grafts between 1983 and 1998 by one senior surgeon were reviewed. Patients in this study were operated on before their late teens and had greater than 1-year follow-up including serial photographic documentation. Nasal growth was determined by comparing anthropometric measurements preoperatively, perioperatively, and postoperatively. Patient satisfaction was determined through a questionnaire that addressed memory, donor-site morbidity, and nasal perception. Independent, blinded skilled observers who reviewed frontal and lateral photographs of the preoperative, perioperative, and postoperative intervals assessed nasal aesthetics. Thirty-two patients who underwent 38 rib graft reconstructions of the nasal dorsum and tip at an average age of 8.8 years constitute the study population. Six patients underwent secondary augmentation. The average interval between initial nasal reconstruction and evaluation for this study was 7.9 years. Comparative anthropometric measurements before and after surgery documented increases in both tip projection (2.3 percent) and nasal length (3.0 percent) and a decrease in nasolabial angle (1.9 percent). Patient satisfaction interview response rate was 100 percent of those whom we were able to contact (28 of 32). The average age at interview was 17.2 years. Most patients recalled the operation and denied recollection of pain. Donor-site long-term morbidity was not an issue for 86 percent of patients. Sixty-four percent of patients remembered their preoperative nasal appearance and 89 percent of these preferred the postoperative change and were not concerned with nasal scars or texture. Almost two-thirds of the patients had fixation screws removed from the nasal dorsum because of skin erosion, easy palpability, or visibility. Although several patients expressed a desire to make minor additional changes to their nose, only one of these elected offered presurgical consultation and none have had such surgery. The postoperative nasal appearance compared with that preoperatively was rated as improved for 66.3 percent of responses, 26.5 percent as unchanged, and 7.2 percent as deteriorated. Cantilevered autogenous chondro-osseous rib graft reconstruction of the nasal dorsum is an effective means of reconstruction for the hypoplastic nose in childhood with respect to morphometric measurements, patient self-perception, and the assessment of nasal appearance by others.  相似文献

Lengthening the nose with a tongue-and-groove technique   总被引:2,自引:0,他引:2  
Guyuron B  Varghai A 《Plastic and reconstructive surgery》2003,111(4):1533-9; discussion 1540-1
Lengthening the short nose is often a major task. The ability to maintain proper alignment between the nasal base and dorsum may prove difficult without sacrificing the suppleness of the former. In this article, the authors introduce a technique of nose lengthening that ensures alignment of the tip with the rest of the nose yet avoids tip rigidity, unless a significant increase in tip projection is also planned. Two spreader grafts are placed, one on either side of the septum, and are extended beyond the caudal septal angle proportional to the planned nasal lengthening. A columella strut, with the cephalocaudal dimension equaling the combination of the width of the existing medial crura plus the amount of planned nasal lengthening, is placed between the medial crura in continuity with the caudal septum and is fixed to the medial crura using 5-0 clear nylon or polydioxanone suture. If additional projection beyond what is achievable by mere placement of a columella strut is required, the strut is fixed to the spreader grafts in a more projected position. Otherwise, the columella strut is simply positioned between the extensions of the spreader grafts. It is necessary to mobilize the lower lateral cartilages to prevent excessive columella show. This procedure has been performed on 23 patients over the past 12.5 years, with 20 patients enjoying good-to-excellent results. The advantages of this technique include its predictability and reproducibility, and the ability to elongate the nose with a mobile nasal base that is in line with the rest of the nose. If suture fixation is used to gain more projection, the technique proves dependable but the nose will become more rigid than is optimal. The requirement of three pieces of properly shaped septal cartilage, which might not be available when a secondary rhinoplasty is performed, is the major disadvantage of this operation. Furthermore, the procedure is, to some degree, labor-intensive.  相似文献

The deviated nose presents a particular challenge to the rhinoplasty surgeon because, frequently, both a functional problem (airway obstruction) and an aesthetic problem must be addressed. An approach to the deviated nose is presented that relies on accurate preoperative planning and precise intraoperative execution of corrective measures to return the nasal dorsum to midline, restore dorsal aesthetic lines, and maintain airway patency. The principles of correction include wide exposure through the open approach, release of all deforming forces to the septum, straightening of the septum while maintaining an adequate dorsal and caudal strut, restoring long-term support, reducing the hypertrophied turbinates, and performing controlled stable percutaneous osteotomies. An operative algorithm is described that emphasizes simplicity and reproducibility, and case studies demonstrate the results that can be achieved with this approach.  相似文献

Grafts to the nasal dorsum and tip, whose local effects are well known, also have distant effects that may not be as readily obvious but that nevertheless are just as real. Dorsal and tip grafts can shorten or lengthen the nose (relatively and absolutely), affect nasal symmetry, preserve or alter nasal ethnic characteristics, and alter dorsum/tip relationships. Each of these properties increases the utility of cartilage and bone grafts in treating a variety of nasal configurations.  相似文献

Endoscopically assisted, intraorally approached corrective rhinoplasty.   总被引:3,自引:0,他引:3  
J T Kim  S K Kim 《Plastic and reconstructive surgery》2001,108(1):199-205; discussion 206-7
In the field of facial surgery, operations that require guesswork can result in unexpected complications. One example of such "blind" facial surgery is the lateral osteotomy procedure in corrective rhinoplasty. In most conventional corrective rhinoplasties, the postoperative results of a lateral osteotomy can be controlled by the surgeon's visual perception or manual dexterity; therefore, an experienced surgeon is indispensable in such elaborate operations. Until now, reports have focused on the endoscopic approach through the nasal dorsum or septum through the nostril. However, because of the difficulty in handling the endoscope with osteotomy instruments, it is considered difficult to perform a precise lateral osteotomy procedure using that approach. The authors think the intraoral endoscopic approach should be considered a viable alternative in corrective rhinoplasty.Through small, bilateral gingivobuccal incisions, both the piriform apertures and nasal bones can be easily exposed, and the exact level of the lateral osteotomy can be confirmed directly under the endoscope. The lateral osteotomy is made simply with a reciprocating saw, and symmetrical cutting can be ascertained during the operation. Sometimes, a particular osteotomy level or the proper repositioning of osteotomed segments can be readily evaluated with assistance from the endoscope during the operation. Eleven cases using this procedure were performed over the past 3 years. These endoscopic repairs for a deviated nose were quite helpful for visual confirmation and accurate correction. No complications occurred when using the endoscope with this procedure.  相似文献

In nose surgery, carved or crushed cartilage used as a graft has some disadvantages, chiefly that it may be perceptible through the nasal skin after tissue resolution is complete. To overcome these problems and to obtain a smoother surface, the authors initiated the use of Surgicel-wrapped diced cartilage. This innovative technique has been used by the authors on 2365 patients over the past 10 years: in 165 patients with traumatic nasal deformity, in 350 patients with postrhinoplasty deformity, and in 1850 patients during primary rhinoplasty. The highlights of the surgical procedure include harvested cartilage (septal, alar, conchal, and sometimes costal) cut in pieces of 0.5 to 1 mm using a no. 11 blade. The fine-textured cartilage mass is then wrapped in one layer of Surgicel and moistened with an antibiotic (rifamycin). The graft is then molded into a cylindrical form and inserted under the dorsal nasal skin. In the lateral wall and tip of the nose, some overcorrection is performed depending on the type of deformity. When the mucosal stitching is complete, this graft can be externally molded, like plasticine, under the dorsal skin. In cases of mild-to-moderate nasal depression, septal and conchal cartilages are used in the same manner to augment the nasal dorsum with consistently effective and durable results. In cases with more severe defects of the nose, costal cartilage is necessary to correct both the length of the nose and the projection of the columella. In patients with recurrent deviation of the nasal bridge, this technique provided a simple solution to the problem. After overexcision of the dorsal part of deviated septal cartilage and insertion of Surgicel-wrapped diced cartilage, a straight nose was obtained in all patients with no recurrence (follow-up of 1 to 10 years). The technique also proved to be highly effective in primary rhinoplasties to camouflage bone irregularities after hump removal in patients with thin nasal skin and/or in cases when excessive hump removal was performed. As a complication, in six patients early postoperative swelling was more than usual. In 16 patients, overcorrection was persistent owing to fibrosis, and in 11 patients resorption was excessive beyond the expected amount. A histologic evaluation was possible in 16 patients, 3, 6, and 12 months postoperatively, by removing thin slices of excess cartilage from the dorsum of the nose during touch-up surgery. This graft showed a mosaic-type alignment of graft cartilage with fibrous tissue connection among the fragments. In conclusion, this type of graft is very easy to apply, because a plasticine-like material is obtained that can be molded with the fingers, giving a smooth surface with desirable form and long-lasting results in all cases. The favorable results obtained by this technique have led the authors to use Surgicel-wrapped diced cartilage routinely in all types of rhinoplasty.  相似文献

LEARNING OBJECTIVES: After studying this article, the reader should be able to: 1. Describe the soft-tissue, cartilaginous, and bony anatomy of the nose. 2. Describe the anatomy and function of the nasal valves. 3. Discuss the governing physiologic principles responsible for airflow dynamics. 4. Discuss the various functions of the nose. 5. Demonstrate an appropriate evaluation of the nasal airway. 6. Discuss the differential diagnosis of nasal obstruction. 7. Discuss appropriate management options for nasal airway obstruction.The nose is a complex, multifunctional organ that requires respect and understanding from the rhinoplasty surgeon. The etiologic and pathologic characteristics of each patient's nasal airway problem determine the treatment of the nasal airway. Frequently, medical management is sufficient without operative intervention. Recent advances have shown that nasal valves in airway patency may play a more important role than the septum. The rhinoplasty surgeon's understanding of the anatomy and physiology of the nasal airway, along with the causes of obstruction, can pave the way for a proper evaluation and appropriate management of nasal airway problems. Lack of understanding can result in misdiagnosis and mismanagement. This article outlines current concepts of medical and surgical management of nasal airway problems and discusses in detail the key concepts and principles in the practical management of the nasal airway.  相似文献

Temporoparietal free fascia grafts in rhinoplasty   总被引:3,自引:0,他引:3  
The temporoparietal fascial graft provides adequate coverage, contour, and bulk on the cartilage dorsum of the nose, as well as an inconspicuous donor site. In my opinion, this technique not only prevents the occurrence of noticeable sharp edges of the cartilage graft, but also adds to the smooth contour of the reconstructed nasal dorsum. The improved results either in primary and secondary rhinoplasty would seem to justify this technique. Some variations in fascia grafts are presented with clinical examples.  相似文献

The rhinoplastic surgeon when faced with nasal sinusitis has traditionally delayed aesthetic treatment of the nose, referring the patient to the ear, nose, and throat consultant until complete resolution of the inflammatory condition. Often, under such a scenario, the patient found the ear, nose, and throat procedure to be a traumatic experience that discouraged further surgery of an aesthetic nature. The advent of functional endoscopic sinus surgery has significantly modified the management of paranasal sinus disorders. This minimally invasive, sophisticated procedure can easily be combined with rhinoplasty. More recently, an endoscopic approach has been advocated for management of the septum and lower/middle turbinates. The authors call this functional endoscopic nasal surgery. Functional endoscopic nasal surgery allows a clearer view of the operative field (septum and turbinates), a more accurate correction of nasal obstruction, and better control of bleeding. Thus, endoscopic techniques permit the treatment of functional and inflammatory nasal disorders in a single stage, along with aesthetic improvement. Only the patient with severe sinusitis is unsuitable for combined therapy. The authors present their experience based on 72 consecutive cases of combined functional endoscopic sinus surgery/functional endoscopic nasal surgery with aesthetic rhinoplasty. Complications were minimal and functional failures were limited to 4 percent, whereas aesthetic outcomes remained uncompromised.  相似文献

Because an increasing number of Hispanic patients are seeking nasal surgical treatment, a critical analysis of 25 consecutive Hispanic rhinoplasties was performed. After a review of the patient data and preoperative photographs, a new classification was developed, based on the type of deformity rather than geographical origins (as previously used). A treatment paradigm is offered for each type of deformity. Type I involves a high radix, a high dorsum, and a nearly normal tip and is often referred to as a Castilian nose. Treatment consists of a closed functional reduction rhinoplasty, with dorsal reduction and minor tip changes. Type II involves a low radix, a normal dorsum, and a dependent tip and is a new designation. Treatment consists of a finesse rhinoplasty with a radix graft, minimal dorsal changes, use of a columellar strut for support, and open tip suturing. Type III involves a broad base, thick skin, and a wide tip deformity, with its worst expression in the mestizo nose. Treatment consists of a balanced rhinoplasty with minimal dorsal alteration but maximal lobular reduction and an open-structure tip graft. The following conclusions with respect to Hispanic rhinoplasty in the United States are important: (1) an enormous anatomical diversity of deformities is present, in contrast to Asian and black noses; (2) three distinct types of deformities have been identified, each of which requires a different surgical approach; (3) a wide variety of surgical techniques are necessary, in contrast to other ethnic noses; (4) conservative dorsal reduction is essential for type II and III noses; and (5) limitations imposed by the skin envelope are far less than presupposed, and the results are better than generally recognized. As the Hispanic population grows and becomes more prosperous, plastic surgeons in the United States can expect to encounter an increasing number of Hispanic patients requesting rhinoplasty.  相似文献

The subunit principle in nasal reconstruction   总被引:26,自引:0,他引:26  
The nasal surface is made up of several concave and convex surfaces separated from one another by ridges and valleys. Gonzalez-Ulloa has designated the nose an aesthetic unit of the face. These smaller parts (tip, dorsum, sidewalls, alar lobules, and soft triangles) may be called topographic subunits. When a large part of a subunit has been lost, replacing the entire subunit rather than simply patching the defect often gives a superior result. This subunit approach to nasal reconstruction causes unsatisfactory border scars of flaps to mimic the normal shadowed valleys and lighted ridges of the nasal surface. Furthermore, as trapdoor contraction occurs, the entire reconstructed subunit bulges in a way that simulates the normal contour of a nasal tip, dorsal hump, or alar lobule. Photographs show five patients in whom this principle was followed and one in whom it was not.  相似文献

I describe a simple technique of full-scale life-size photography using marker/stickers and a ruler at the side of the face as an index for magnification. I also report a technique of soft-tissue cephalometric analysis that consists of some new proportion and some old angles and measurements. This technique will enable the plastic surgeon, even if not artistically inclined, to draw an aesthetically pleasing and very proportionate profile outline of the nose and measure the proportions of the front view on the majority of patients. The difference between the patient's nasal outline and the planned nasal definition is then measured and expressed in quarters of millimeters to give the surgeon a very precise numeric guide for surgery. This will help the plastic surgeon define the aesthetic goals very accurately and also might be helpful in detecting other facial disharmonies that might be influential in the outcome of the rhinoplasty. Using this technique of analysis, along with the prediction guidelines extrapolated from my study on soft-tissue response to surgical alteration, one can develop a fairly predictable approach to rhinoplasty.  相似文献

There is general agreement that when discussing surgery with the prospective rhinoplasty patient, one may also include discussion of the chin because of the important interrelationship between these two regions. It is apparent that on the profile-lateral view, the four prominences-the forehead, nose, chin, and neck-balance and complement one another. The cervical region, the fourth dimension, was examined to estimate the aesthetic significance of the nasal-to-cervical relationship and to determine the implications to rhinoplasty surgery.Part I of the study was a survey to test the hypothesis that the cervical region affects the perceived impression of the nose. Four standard facial-profile black-and-white photographs were chosen to represent varying degrees of nasal dorsum hump and cervical ptosis problems. Using computer-altering software, only the cervical regions were altered to create a pair of photographs for each of the four profiles: one with a youthful-looking non-ptotic cervical region, the other with a ptotic aged-looking cervical region. Raters were asked to give their first-impression opinions of which nose subjectively appeared "better." Raters consistently (84 percent of the time) chose the nose on the faces with the less ptotic neck as being better. Therefore, a less ptotic neck improved the perceived appearance of the nose.Part II was a retrospective chart review of the rhinoplasty patients of a single surgeon by independent raters. To estimate the aesthetic significance of the nasal-to-cervical relationship, the proportion of patients undergoing rhinoplasty surgery who could have potentially benefited from a youth-restoring neck procedure was determined. Criteria originally described by Ellenbogen and Karlin for judging the results of youth-restoring neck procedures were used as relative indications for neck surgery. An average of 27.2 percent of the patients did not have visible criteria and therefore by definition had relative indications for neck-rejuvenating procedures when undergoing rhinoplasty surgery. As demonstrated in part I of the study, improving the neck could improve the perceived results of the rhinoplasty.Part III of the study validated the Ellenbogen and Karlin criteria. The present authors found that the original criteria were probably based on female patients, that male and older patients had more indications for surgery, and that there was significant interrater agreement with the youthful criteria.In summary, the authors established that a strong nasal-to-cervical relationship exists whereby the perceived appearance of the nose is affected by the neck. The significance of this relationship to rhinoplasty surgery was determined, and it was found that more than 27 percent of rhinoplasty patients could obtain better perceived nasal results with a concomitant neck-rejuvenating procedure. Consequently, discussing neck-rejuvenating procedures with the rhinoplasty patient is valuable.  相似文献

A case of successful replantation of the nose is presented. Two arteries and one vein were anastomosed, providing a stable framework for direct revascularization of the amputated nasal segment. This resulted in complete survival of the nose, with an excellent aesthetic result. However, despite successful microsurgical arterial and venous repair, significant postoperative blood loss still occurred as a result of anticoagulation. In cases of the amputation of specialized structures, the improved functional and cosmetic result obtained with replantation must be weighed against the risk of blood-borne disease transmission when postoperative transfusion is required. Recognizing the potential need for postoperative transfusion in these cases is important in allowing the surgeon to exercise appropriate judgment in deciding whether replantation should be performed.  相似文献

Nasal reconstruction has been analyzed extensively in adults but not in children. The purpose of this article is to review the authors' experience with the forehead flap for nasal reconstruction in 10 children under the age of 10 during a 10-year period. Outcomes were assessed by an objective grading system for cosmetic surgical results. Subjective criteria were also applied by an assistant surgeon and by the patients' relatives. Appropriate results were obtained by the following principles: (1) A modified approach that considers three subunits consisting of the dorsum, tip, and ala was used; (2) a forehead flap is the best option for an entire subunit or a full-thickness defect repair; (3) the forehead flap design should be paramedian, oblique, and opposite to the major defect to avoid the hairline and allow better caudal advancement; (4) ear or costal cartilages are good options for structural support (the septum is a nasal growth center that should not be touched); (5) infundibular undermining of vestibular mucosa, turnover flaps, and skin grafts are good options for internal lining; (6) reconstruction is a three-stage procedure (an intermediate operation is added to thin the flap and perform secondary revisions for lining and support); (7) reconstruction should be completed before the child is school aged, to achieve good aesthetic results immediately and avoid psychosocial repercussions; and (8) the reconstructed nose, with skin, lining, and support, will grow with the child (no final surgery should be planned at the age of 18, other than revisions of late complications).  相似文献
