Let-Down Rhinoplasty in Patients With Cleft Lip Nose.

Rhinoplasty in patients with cleft lip nose (CLN) deformity is challenging. Cleft lip nose deformity primarily affects the nasal tip, columella, nostrils, alar base, floor, and septum. The needs of patients with CLN are quite different from those of patients who undergo primary rhinoplasty. Recently, the dorsal preservation rhinoplasty technique has gained popularity. We applied this technique to patients with CLN deformity to obtain better aesthetic and functional results. Ten consecutive patients with indication for primary CLN reconstruction underwent let-down rhinoplasty. Rhinoplasties were performed using either the closed or open approach, with costal cartilage grafts and full-thickness skin grafts. A rhinoplasty outcome evaluation questionnaire was used to assess the results. Moreover, the use of the same questionnaire in prior patients allowed us to compare results between our previous and new techniques. The study included 6 female and 4 male patients, with ages ranging from 18 to 25 years. Only 1 patient had a history of bilateral cleft lip. Seven patients had a history of left-sided cleft lip, and 2 patients had right-sided cleft lip. Open-approach let-down rhinoplasty with costal cartilage grafts and full-thickness skin grafts was performed in 8 patients, whereas closed-approach let-down rhinoplasty with costal cartilage grafts was performed in 2 patients. Columellar struts and affected-side onlay costal cartilage grafts were used in all patients. All patients reported being satisfied with the let-down rhinoplasty outcome, and none complained of functional problems. However, nostril symmetry was not observed in some patients, particularly in patients who underwent closed-approach rhinoplasty. Combining open approach, full-thickness skin graft, costal cartilage graft, and let-down rhinoplasty shows promising and satisfactory outcomes in patients with CLN. However, further studies are required to confirm this observation.

Modified Alar Base Reduction: A Novel Technique.

Alar base reduction (ABR) surgery is one of the rhinoplasty techniques used to reduce alar flaring, nasal base width, or both. It is crucial for rhinoplasty surgeons to understand and analyze the type of nasal base deformity to achieve satisfactory results and avoid complications. The objective of this study is to describe a novel technique of ABR that addresses alar flaring while avoiding violation of the nostril marginal rim. This prospective cohort study included patients with alar flaring who underwent rhinoplasty or septorhinoplasty with ABR using our modified technique. Demographic data, clinical history, aesthetic concerns, and preoperative and postoperative photographs were collected for each patient. The surgical outcome was assessed using subjective scar evaluation scores at 3 and 6 months, the Stony Brook Scar Evaluation Scale at 6 months, and an overall appearance satisfaction score. A total of 8 patients were included in the study. Subjectively, the majority of patients (75%) reported satisfactory scar appearance at the 6-month follow-up. The mean Stony Brook score was 4.7 (SD=0.74). Nostril symmetry was achieved in all patients. Seventy-five percent of the participants expressed satisfaction with the overall appearance. Our modified ABR technique demonstrates promising results in correcting alar flaring while achieving nostril symmetry with an acceptable scar. Further studies with a larger sample size are needed to evaluate the feasibility of the technique and compare it to other classical techniques. Level IV.

Dynamic Molding of Cleft Nasal Cartilage in Unilateral Complete Cleft Lip and Palate Using Simple Segmented NAM.

Nasal morphology remodeling by nasoalveolar molding (NAM) before primary lip repair gives better post-surgery outcomes. However, traditional NAM has high technical sensitivity, a steep learning curve, frequent need for modifications, and interrupts lifting forces on the nasal cartilage during oral movements, thereby reducing overall efficacy of device. To eliminate interaction and interdependency of the nasal bulb with alveolar molding plate, we propose segmenting NAM (SNAM) into nasolabial complex molding (NCM) and alveolar complex molding (ACM). NCM addresses ala-septum, lip-premaxilla via lambda-nasal hook and lip taping. ACM addresses palate-alveolus via Yen-modified feeding plate. When the hook is suspended by elastic traction, nasal complex undergoes a natural rotation, where cleft-side ala lifts and septum medializes. Lip taping and feeding plate augment positive molding of cleft segments and maintain transverse relation. The current study outlines SNAM treatment strategy and assesses the effect on nasal deformity. Retrospective observational cohort study set in a comprehensive cleft care centre. Twenty patients with unilateral complete cleft lip and palate who underwent SNAM were selected. Retrospectively, standardized basilar views, pre-, and post-SNAM therapy were evaluated for nostril height, and nostril width, as a ratio of cleft to non-cleft side along with columellar deviation angle. SNAM resulted in significantly improved nostril symmetry with no complications observed. Nostril height ratio increased from 0.35 ± 0.10 to 0.78 ± 0.17. Nostril width ratio decreased from 3.14 ± 0.66 to 2.18 ± 0.42. Columellar deviation angle increased from 26.5 ± 6.30 to 58.5 ± 9.88 degrees. Dynamic correction of the nasal deformity in UCLP is possible through SNAM therapy.

Septal Reposition during Intermediate Cleft Rhinoplasty: A Second Chance for Correcting Caudal Septal Deviation.

The authors investigated postoperative nasal morphologic changes in patients undergoing secondary correction of cleft-lip nose with septal repositioning and alar cartilage suspension during preschool age. The authors performed a retrospective review of 77 patients who underwent secondary correction of cleft-lip nose. The patients were 5 to 6 years of age and underwent intermediate rhinoplasty by alar cartilage suspension, with or without septal repositioning. They were divided into 2 groups based on time, encompassing septal repositioning (September of 2015 through November of 2017) and control (November of 2009 through August of 2015) groups. The authors performed a photogrammetric comparison by assessing the postoperative nasal morphologic changes using linear and angular measures. The cleft-to-noncleft-side ratio of each parameter was measured for the nostril width and height, nostril area, and caudal septal deviation angle. Among the 77 patients, 43 were selected as the septal repositioning group and 34 as the control group. Evaluation timing was 5.32 ± 0.45 years of age for the preoperative period (T0), 6.57 ± 0.5 years of age for short-term follow-up (T1), and 9.28 ± 0.65 years of age for long-term follow-up (T2). The septal repositioning group showed significantly improved nostril width ratio and caudal septal deviation angle in the T1 and T2 periods. Septal repositioning significantly decreased the nostril area ratio in the T1 and T2 periods due to decreased cleft-side and increased noncleft-side nostril area. The secondary correction of cleft-lip nose with septal repositioning during preschool age offers a second chance to correct nasal appearance by balancing the nostril symmetry and correcting the caudal septal deviation.

Outcome Comparisons of Two Different Orbicularis Oris Muscle Reconstruction Techniques in Patients with Unilateral Incomplete Cleft Lip.

The long-term postoperative outcomes of two different orbicularis oris muscle reconstruction techniques in patients with unilateral incomplete cleft lip were compared. Forty-seven patients with unilateral incomplete cleft lip were assessed in this study, where 23 underwent a traditional method of reconstruction and 24 underwent a novel method. Preoperative measurements, postoperative results, and 3-year follow-up outcomes were measured by photographic anthropometric analysis. Five upper lip measurement indices and 8 nostril indices were included. The postoperative outcomes showed that the shape of the lip and nose was more symmetric with the new surgical method compared with the conventional technique. Long-term outcomes after 3 years, although characterized by minimal changes during maxillofacial development, showed better maintenance of lip and nostril symmetry in the novel-method group. The novel technique seeks to balance the perinasal and perioral muscles, resulting in improved symmetry compared with the traditional reconstruction technique. Therapeutic, III.

The Effectiveness of Releasing the Lower Lateral Cartilage Through Intranasal Z-plasty Incision on the Vestibular Web During Secondary Correction of Nasal Deformities in Complete Unilateral Cleft Lip and Palate.

The primary goal in the secondary correction of unilateral cleft lip nose deformity is to achieve symmetry of the nose and nostril. This study aimed to investigate the efficacy of freeing the lower lateral cartilage from the pyriform ligament through an intranasal Z-plasty incision on the vestibular web in adult patients with complete unilateral cleft lip and palate. Thirty-six patients with complete unilateral cleft lip and palate, who underwent open rhinoplasty between August 2014 and December 2021, were identified retrospectively. Five parameters for nose form and nostril symmetry were measured on basal views through 2-dimensional photographic analysis. The patients were divided into subgroups with or without septoplasty. Cleft-to-non-cleft ratios between the Z (13 patients) and non-Z groups (23 patients) were compared using the Mann-Whitney U test. The mean follow-up was 12.9 months (6-31mo). In the Z group, there were significant differences between the preoperative and postoperative values for nostril angulation, regardless of septoplasty (all P <0.05). Despite septoplasty, significant differences in the postoperative changes in nostril angulation were found between the Z and non-Z groups (all P <0.05). Intranasal Z-plasty on the plica vestibularis is an effective technique for releasing the lower lateral cartilage, improving the nostril asymmetry in cleft lip nose deformity.

Application of 3D printed nasal vestibular support in the treatment of anterior nostril stenosis

Objective:To evaluate the efficacy of 3D printed nasal vestibular support on the recovery of nasal ventilation function and nostril shape after nostril stenosis treatment. Methods:Thirty-eight patients with unilateral traumatic nasal vestibular stenosis were selected and treated with 3D printed nasal vestibular support after operation. Subjective evaluation indicators, objective nostril local morphological and structural parameters, and nasal airflow dynamics parameters by numerical simulation were used. To evaluate the nostril morphological and nasal functional recovery after treatment. Results:The subjective nasal congestion and nostril symmetry satisfaction VAS scores of the patients after nasal vestibular support treatment were improved to varying degrees compared with those before surgery; The nostril morphological parameters showed that the Δlong-axis ratio and Δ short-axis ratio were significantly decreased after nasal vestibular support therapy （0.09±0.09 and 0.16±0.13） compared with those before surgery（0.21±0.20 and 0.28±0.21） respectively（P<0.01）. And the cross-sectional area of the nasal valve on the stenotic side nasal cavity increased from（0.40±0.27） cm² before operation to （0.71±0.26） cm² after treatment（P<0.01）; The nasal resistance on the stenosis side nasal cavity also decreased from （0.036±0.024） Pa·s/mL before operation to （0.022±0.008） Pa. s/mL after treatment（P<0.01）, and the total nasal resistance was decreased from （0.033±0.02） Pas/mL before operation to （0.021±0.007）Pa. s/mL after treatment（P<0.01） ; It also showed that NWE（nasal warming efficiency） and NHE（nasal humidification efficiency） on the stenotic side nasal cavity were significantly decreased after nasal vestibular support therapy（[95.92±2.8]% and [94.55±4.17]%） compared with those before surgery （[97.94±1.97 ]% and [96.19±2.94]%） respectively（P<0.01）. Conclusion:The 3D printed nasal vestibular support for postoperative support treatment on patients with anterior nostril stenosis can reflect the advantages of personalized treatment and allow patients to obtain satisfactory results, and the use of individually designed 3D printed nasal vestibular support can make the shape of anterior nostrils and nasal cavity normal ventilation function recover well, its clinical application prospect is worth looking forward to.

Comparison of nasal symmetry in closed, semi-open and open tip rhinoplasty following primary cleft lip repair

Aim: The purpose of the present research was to assess the amount of nasal symmetry achieved through closed, semi-open, open tip rhinoplasty after primary cleft lip repair. Methodology: Protocol was registered on the PROSPERO register of systematic reviews. PRISMA-P guidelines for the conduct of systematic review were followed. Literature search was done in various databases. The inclusion criteria were patients with non-syndromic unilateral cleft lip undergoing rhinoplasty with primary cleft lip repair and preference given to studies comparing the 3 procedures. Results: Sixteen articles were selected based on inclusion criteria after screening 522 articles—1 randomized controlled trial, 2 retrospective cohorts, and 13 case series. Both closed and open techniques have achieved good symmetry of nostrils with no impairment of growth. No advantage of one technique over the other was noted. Conclusion: There is a paucity of randomized controlled trials and prospective studies on the subject to arrive at an evidence-based recommendation as to whether open or closed rhinoplasty during primary cleft lip repair gives better long-term outcomes

Augmentation Rhinoplasty in Cleft Lip Nasal Deformity Using Alloplastic Material and Autologous Cartilage.

Secondary cleft rhinoplasty typically requires large amounts of cartilage grafts for augmentation. The purpose of this study was to present our short-term experience with alloplastic implants in cleft rhinoplasty. This was a retrospective cohort study of cleft lip and palate patients treated with secondary rhinoplasty at Hanoi Medical University Hospital and Ruby Hospital between 2017 and 2020. All rhinoplasty procedures consisted of lower lateral cartilage repositioning, a dorsal augmentation with silicone implant, columellar strut implant or graft, and onlay tip grafts. Cartilage was obtained from the septum and concha, and no cartilage was harvested from the rib. The study outcomes included the Rhinoplasty Outcome Evaluation (ROE) survey, a modified Mortier scoring scale, 8 intranasal measures of symmetry, and 4 nasofacial measures of tip projection and nasal length. Changes in patient satisfaction and nasal esthetics were compared before and after surgery. A total of 38 patients were included in the final study sample, of whom 65.79% had unilateral clefts. The overall complication rate was 7.89%, and there were 2 cases of infection and 1 case of dorsal implant displacement. Following rhinoplasty, ROE satisfaction scores significantly increased (+39.36, P <0.01) and Mortier severity scores decreased (-3.06, P <0.01). Nostril symmetry nearly normalized in width, height, and inclination. Mean columellar deviation decreased from 8.82 to 2.08 degrees, and nasal projection increased as assessed on multiple analyses. Patients with bilateral clefts had similar improvements in ROE and Mortier scores. In our experience, synthetic implants simplified the correction of cleft nasal deformity and eliminated the need for costal cartilage. We found that our protocol produced acceptable and stable short-term clinical results without increasing the complication rate above what has been reported with autologous grafts.

One-Stage Repair of Alveolar Cleft and Nasal Deformities Using Grafts From Nasal Septum: Application of Vomer, Ethmoid, and Septal Cartilage

Background: Patients with alveolar cleft unrepaired suffer from nasal deformities of different magnitude. Bone and cartilage grafts are harvested through several incisions. In this study, we present a method to simultaneously correct nasal deformities and repair alveolar cleft using grafts from the nasal septum. Patients and Methods: All 6 patients with unilateral cleft lip and palate have alveolar cleft unrepaired combined with nasal deformity. Computed tomography scans and 3-dimensional-printed models of vomer and ethmoid bone were used for the purpose of preoperative design and for assessing the magnitude of deformity. Grafts of bone and cartilage from deviated septum were harvested by septoplasty through which dorsum deviation was corrected. Bone grafts from vomer and ethmoid were then fixed to the prepared alveolar cleft to repair the defect and elevate the alar base. Septal cartilage was adjusted into different shapes of grafts and deformities of nasal tip, nostrils, and columella were then corrected by rhinoplasty to restore the symmetry of the nose. Results: Symmetry of nostrils was improved. The height of alar base on the cleft side was elevated to the level close to the noncleft side. Deviation of the septum, nasal dorsum, and columella was corrected. Projection of the nasal tip was adjusted to facial midline. Midface aesthetics was generally improved. Conclusion: Application of septal grafts reduce the number of incisions. One-stage repair of alveolar cleft and nasal deformities, with the aid of digital design, improves the postoperative experience and the general outcome of the surgery.

Inferiorly Based Alar Groove Flap for Correction of Alar Base Malposition and Nasal Stenosis.

Summary:When the external nasal valve (ENV) is excessively narrow or lacks support, nasal obstruction can develop causing decreased airflow. Although cartilage grafts may support a collapsed nasal ala, addressing severe nasal stenosis requires further intervention. Techniques to move flared ala inward are well-known; however, repositioning a medially displaced alar base is less commonly described. Our surgical team developed an inferiorly based alar groove flap to achieve lateral movement of a malpositioned alar base, with goals of widening the ENV and improving nasal symmetry and cosmesis. A retrospective chart review was performed on a series of five patients over a two-year period. Charts were reviewed for demographic data, medical and surgical history, functional airway complaints, and subjective aesthetic concerns. All patients presented with unilateral ENV collapse, alar base malposition, and nostril asymmetry. Our operative method consisted of repositioning the affected alar base laterally and inferiorly to alleviate nostril stenosis and using an alar rim graft to support the ENV. Postoperatively, all patients demonstrated immediate alleviation of subjective nasal obstruction and improvement in size of ENV aperture, nostril symmetry, and overall cosmesis. Four patients showed lasting postoperative results. One patient experienced restenosis by 4 months and required revision. Our inferiorly based alar groove flap provides a reproducible solution for repositioning a medially displaced alar base. This technique reliably corrects ENV stenosis, relieves airway obstruction, and improves nasal symmetry and cosmesis.

P74. A HIP WAY TO RECONSTRUCT NOSES: OUTCOMES WITH ILIAC CREST CAP CARTILAGE GRAFTS IN INTERMEDIATE CLEFT RHINOPLASTY

PURPOSE: This case-control study evaluated the trends and outcomes of iliac crest cap cartilage (ICCC) grafts in an intermediate mixed-dentition (IMD) cohort undergoing cleft rhinoplasty. METHODS: From 2006 to 2020, our institution performed 959 cleft rhinoplasties, 304 during IMD of which 140 underwent tip rhinoplasty with ICCC grafts concomitantly with alveolar bone grafting. Appropriate cohort and subgroup statistical analyses and regression modeling were completed. Photomorphometric (PMM) analyses on basal, frontal and lateral views were conducted comparing cohorts with and without ICCC grafts and assessing nasal symmetry, protrusion and nasolabial angles. RESULTS: There were no statistically significant differences between the ICCC cohort and controls regarding sex, cleft laterality, or surgical age (all p>0.1). There was a statistically significant increase in institutional use of ICCC over time (p<0.001), without correlation to sex, laterality, or age at surgery (all p>0.05). Within a subgroup of now skeletally mature patients, the prior use of ICCC was significantly correlated with a decreased incidence of requiring further rhinoplasties (φ=0.2195; p=0.0176). PMM analyses demonstrated the unilateral cleft ICCC cohort had superior improvement in nasal symmetry postoperatively relative to controls (p=0.0277) but was otherwise comparable to controls, in nostril symmetry (p=0.696) and tip projection (p=0.334). No patients had iliac crest contour irregularities with functional sequelae. CONCLUSION: ICCC provides an abundant source of cartilage for cleft rhinoplasty in the period of IMD concomitant to alveolar bone grafting. Our data demonstrates comparable or improved aesthetic outcomes with ICCC without additional morbidity and provides reassurance on ICCC’s retention over time.

Nasal molding prevents relapse of nasal deformity after primary rhinoplasty in patients with unilateral complete cleft lip: An outcomes-based comparative study of palatal plate alone versus nasoalveolar molding.

ObjectivesIn recent years, many studies have reported that the presurgical nasoalveolar molding method improves the nose morphology; however, the reason for its effectiveness after surgery has never been understood. We evaluated the effect of nasoalveolar molding by comparing it with a passive orthopedic method without a nasal stent and focusing on the nostril morphology after primary cheiloplasty using various measurement methods. We then analyzed the essential factors.Materials and methodsThe patients involved were 31 infants with unilateral complete cleft lip and palate treated with primary cheiloplasty at the University of Tsukuba Hospital from 2004 to 2011. Of the 31 infants, 16 received nasoalveolar molding treatment and 15 received passive orthopedic treatment as controls. Photographic facial measurements were performed for all patients immediately and 7 months after primary cheiloplasty. The esthetics of the nostrils were assessed according to the left–right nostril symmetry, as measured by the Hausdorff distance, area ratio, perimeter ratio, and aspect a/u (the aspect ratio of the affected side)/(the aspect ratio of the unaffected side) ratio. In addition, the inclination of the nasal ridge was assessed using anthropometric measurements (Grc‐Grn∠midline and midline∠columellar axis).ResultsThe area ratio, perimeter ratio, and Grc‐Grn∠midline were significantly greater in the nasoalveolar molding group immediately after surgery (p = 0.00062, 0.016, and 0.048, respectively) than in the control group. However, the Hausdorff distance and aspect a/u ratio were more favorable (p = 0.0018 and 0.0039, respectively) in the nasoalveolar molding group after 7 months.ConclusionsThe results of our study suggested that using nasoalveolar molding as a presurgical orthopedic treatment could improve the shape of the nasal cartilage with surgeon's corrections.

Improving Nasal Symmetry with Alar Composite Graft: Technique and Outcome Assessments in Cleft Patient

PurposeResidual cleft nasal deformities after initial cleft repair can have long-term cosmetic and psychological impact on patients. The authors describe a novel technique of an alar composite graft for patients with cleft lip and/or palate and assess the surgical outcomes with respect to symmetry of individual anatomical components. Materials and methodsThis was a retrospective study of patients with a history of cleft lip/palate who underwent rhinoplasty with alar composite graft placement by the senior author from March 2014 to January 2021. Patients who had high-quality pre-operative and postoperative 3D imaging were included. Patient age, sex, surgical history, cleft side, cleft details, and operative details were recorded. The primary operative technique includes the following: 1) Weir and sill excision at the donor side, 2) composite graft harvest, 3) Weir and sill incision at the recipient side, 4) graft placement, 5) closure of the incision sites. Three-dimensional imaging was obtained pre-operatively and postoperatively using Vectra M3 3D Imaging (Canfield Imaging System, Fairfield, NJ). Linear and surface area measurements were made on donor and recipient sides. The difference in measurements was calculated to analyze the degree of similarity across sides, and this difference was compared pre-operatively to postoperatively.1,2 Symmetry of the patient's nostrils and overall nasal symmetry was compared pre-operatively and postoperatively using root-mean-square deviation (RMSD), with smaller values indicating more symmetry. Differences between preoperative and postoperative measurements were calculated with a paired T-test. ResultsOut of 10 patients undergoing the surgery, 8 were able to be included in this study. On lateral view, the donor and recipient sides were more similar postoperatively compared to pre-operatively with respect to lateral alar-columellar disproportion (1.040 versus 3.324, P = .005) and nostril area (0.466 versus 1.065, P = .001) . On basal view, postoperative results showed more similar measurements comparing the donor and recipient sides in nostril height (1.461 versus 3.542, P = .012), nostril width (0.956 versus 2.222, P = .033), nasal dome height (1.597 versus 3.822, P = .024), and nostril surface area (0.188 versus 0.531, P = .015). On symmetry analysis, the overall external nose was more symmetrical after placement of the alar composite graft (1.094 vs 1.772, P = .015). ConclusionCleft lip and palate can cause significant asymmetry related to the nostrils, ala, and overall appearance of the nose. The alar composite graft is a useful technique to improve symmetry over a wide range of dimensions on lateral, basal, and frontal views.

Correcting Wide Alar Base and Flare With Combined Sill and Alar Excision in Asian Patients.

Obvious scar and deformities are commonly observed with incision anterior to the alar-facial groove in alar excision surgery. The authors explored modified sill and alar excision to correct wide alar base and flare synchronously and decreased incident of unacceptable scar and deformities in Asian patients. The authors conducted a retrospective cohort study including 52 consecutive patients undergoing this surgery. Contrary to previous studies, the incision for alar excision was located in the alar-facial groove and was closed by intracutaneous suture. Scars were assessed with visual analog scale and the Stony Brook Scar Evaluation Scale. Ratio of the interalar distance to intercanthal distance, nostril shape, and nostril symmetry was recorded. The mean follow-up time was 18 months. Visual analog scale results showed 50 patients (96.2%) reported unnoticeable scar and 2 noticeable but acceptable scar. Stony Brook Scar Evaluation Scale results indicated 49 patients (94.2%) with good scar outcomes and 3 (5.8%) with moderate scar outcomes. The mean ratio of interalar distance to intercanthal distance reduced significantly from preoperative 1.10 to postoperative 1.02. The frequency of horizon-shaped nostrils changed from preoperative 16 cases (30.8%) to postoperative 2 cases (3.8%). The frequency of the pear-shaped (preferred shape) nostrils improved from preoperative 15 cases (28.8%) to postoperative 26 cases (50.0%). The frequency of symmetrical nostril shape improved from preoperative 36 patients (69.2%) to 42 (80.8%). There were no patients with complications like alar deformities, and patients' dissatisfaction. When performing sill and alar excision in Asian patients, the authors recommended a modified approach with the incision for alar excision being placed in the alar-facial groove and closed by intracutaneous suture, which can avoid obvious scar and deformities in Asian patients.Level of evidence: Level 4.

Change in nostril ratio after cleft rhinoplasty: correction of nostril stenosis with full-thickness skin graft.

BackgroundPatients with secondary deformities associated with unilateral cleft lip and nose might also suffer from nostril stenosis due to a lack of tissue volume in the nostril on the cleft side. Here, we used full-thickness skin grafts (FTSGs) to reduce nostril stenosis and various methods for skin volume augmentation. We compared the changes in the symmetry of both nostrils before and after surgery.MethodsFrom February 2016 to January 2020, 34 patients underwent secondary cheiloplasty and open rhinoplasty for secondary deformities of the unilateral cleft lip and nose with nostril stenosis. FTSG was used on the nostril floor, nasal columella, and alar inner lining. The measured nasal profile included the nostril surface, nostril circumference, width of the nostril floor, and distance from the alar-facial groove to the nasal tip. The “overlap area,” which was defined as the largest overlapping area when the image of the cleft nostril was flipped to the left and right and overlaid on the image of the normal side nostril, was also calculated. The degree of symmetry was evaluated by dividing the value of the cleft side by that of the normal side of each measured profile and expressed as “ratios.”ResultsThe results of all profile ratios, except for the nostril floor width, became significantly close to 1, which represents full symmetry. The overlap area ratio improved from 62.7% to 77.3%, meaning that the length and width of the nostril as well as the overall shape became similar (p<0.05).ConclusionWhen performing cleft rhinoplasty with nostril stenosis, FTSG is useful to achieve symmetry in the nostril size and shape. Skin grafting is simpler to perform than the other types of local flap, and the results are generally satisfactory.

The Utility of the Subalar Graft in Nostril Symmetry in Rhinoplasty.

A deviated nose can be attributable to multiple anatomical factors, including asymmetric maxilla. A subalar graft helps to correct maxillary hypoplasia and may be a useful tool for correcting a deviated nose. The authors' objective is to show the effects of the subalar graft in improving nostril symmetry and to propose an algorithm for using this graft in open and endonasal rhinoplasty. A retrospective case series was performed on patients who had undergone rhinoplasty performed by the senior author (R.W.) from September of 2008 to July of 2015. Patients with at least 3 months of follow-up and adequate photographs were included. The mean follow-up period was 11.0 months (range, 3 to 72 months). A total of 68 patients were included. Preoperative and postoperative photographs were analyzed to measure changes in nasal axis deviation, alar facial angle on base view, alar facial angle on frontal view, and nostril show bilaterally. Of the 68 patients, statistically significant improvement of nasal axis deviation of 4.32 degrees toward the midline was observed. Alar facial angle on base view was improved 1.01 degrees toward the horizontal. Nostril symmetry also improved based on the ratio between the shorter side and the longer side. The mean change in nostril show ratio was 0.19 toward a 1:1 ratio. Previous studies have shown that the subalar grafting technique is an important adjunctive technique in rhinoplasty for patients with midfacial asymmetries. This case series demonstrates that this technique can provide sustained results in the correction of the nasal foundation. Therapeutic, IV.

Reconstruction of Congenital Alar Rim Defects (Tessier Number 1 Cleft) Using Laterally Based Alar Subunit Rotation Advancement Flap.

Alar rim defects develop in most cases as a result of burns, trauma, or tumor excision. Congenital alar rim defects are rare, with an incidence of 1 in 20,000 to 40,000 live births. Tessier classification is the most commonly used classification system for craniofacial defects. Facial clefts involving the nose are categorized as types 0, 1, 2, and 3, whereas cranial clefts with nose lesions are categorized as types 11, 12, 13, and 14. The patterns of nasal clefts are extremely variable, ranging from a simple notch of alar margin to complex craniofacial cleft involving the lip, nose, eyelid, brow, forehead, and underlying bone. This study was conducted at Fayoum University Hospital on 8 male patients who present with congenital alar rim defects (Tessier number 1 cleft). Surgeries were performed under general anesthesia with orotracheal intubation. A full-thickness incision was created along the whole alar subunit, keeping the ala attached only laterally (laterally based alar full-thickness flap). The alar flap was advanced and rotated medially and inferiorly and sutured to the anatomical place in 2 layers, skin and mucosa. Follow-up was done at least 1.5 years postoperatively. The study was conducted on 8 male patients presenting with congenital alar rim defects (Tessier number 1 cleft). The mean age of patients was 14.2 years, and the cleft was unilateral in 4 patients (50%) and bilateral in 4 patients (50%). The patients were assessed both aesthetically and functionally and followed at 1.5 years postoperatively. The aesthetic outcome was assessed according to both patients' and author's evaluations of the scar appearance, alar symmetry, nostril symmetry, and general satisfaction. Laterally based alar subunit rotation advancement flap is a reliable option for reconstruction of congenital alar rim defects (Tessier number 1 cleft) with the advantages of being an easy single-stage procedure with good tissue matching and nostril symmetry and only limitation of extremely wide defects with deficient tissues between the ala and tip.

Correction of Post-Cleft Lip Nostril Floor Stenosis: Para-Alar Flap Combined With Lip Revision.

Post-cheiloplasty nostril floor stenosis is a scarcely reported secondary deformity. The aim of the current study was to assess the outcome of para-alar flap for management of nostril floor stenosis post-unilateral cleft lip repair. This is a retrospective case series study reviewing consecutive patients presenting with nostril floor stenosis following repair of unilateral cleft lip who were managed by the inferiorly based para-alar flap and lip revision. Differential nostril width was measured preoperative, immediate, and late postoperative. We reported 8 patients (3 boys and 5 girls) with an average age of 9.8 years (range: 4.5-19). Satisfactory results with good nostril symmetry measures were achieved, and no restenosis has been observed during the follow-up periods. The donor site scars were negligible. There was no reported partial or total flap loss. Para-alar flap was found to be an effective reconstructive option for patients with nostril floor stenosis post-unilateral cleft lip repair and can be combined safely with cleft lip revision.

Correction of the deviated tip and columella in crooked nose.

The primary procedural components of deviated nose correction are as follows: osteotomy to correct bony deviation, septal deviation correction, manipulation of the dorsal septum to correct upper lateral cartilage deviation, and correction of functional problems (manipulation for correction of internal valve collapse and hypertrophy of the inferior turbinate). The correction of tip and nostril asymmetry cannot be overemphasized, because if tip and nostril asymmetry is not corrected, patients are unlikely to provide favorable evaluations from an aesthetic standpoint. Tip asymmetry, deviated columella, and resulting nostril asymmetry are primarily caused by lower lateral cartilage problems, which include deviation of the medial crura, discrepancy in the height of the medial crura, and asymmetry or deformity of the lateral crura. However, caudal and dorsal septal deviation, which is a more important etiology, should also be corrected. A columellar strut graft, correction of any discrepancy in the height of the medial crura, or lateral crural correction is needed to correct lower lateral cartilage deformation depending on the type. In order to correct caudal septal deviation, caudal septal shortening, repositioning, or the cut-and-suture technique are used. Surgery to correct dorsal septal deviation is performed by combining a scoring and splinting graft, a spreader graft, and/or the clocking suture technique. Moreover, when correcting a deviated nose, correction of asymmetry of the alar rim and alar base should not be overlooked to achieve tip and nostril symmetry.
