[PMID: 39244388 DOI: 10.1016/j.jcms.2024.08.011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2024] [Revised: 04/24/2024] [Accepted: 08/19/2024] [Indexed: 09/09/2024] Open
Abstract
The aim of this study is to evaluate the changes in nasolabial soft tissues following Le Fort I osteotomies, focusing on the impact of maxillary vertical repositioning. This retrospective study included 39 patients with a history of Le Fort 1 osteotomy between 2013 and 2021. Patients were grouped based on their maxillary movement into three categories: pure advancement (group A), advancement with impaction (group B), and advancement with downward repositioning (group C). Preoperative and postoperative CBCT (Cone Beam Computed Tomography) data were analyzed to measure the changes in nasolabial soft tissues. The current study utilized Mimics Suite 20.0 for measuring linear and angular variables. The evaluated variables included intercanthal distance, nasal dorsal length, tip protrusion, mouth width, alar width, upper lip height, nostril dimensions, and angles of nasolabial, alar base, and upper lip. Among them intercanthal distance, nasal dorsal length, or tip protrusion showed no statistical difference (p > 0,05). Mouth width, alar width, alar base angle were increased and upper lip angle was decreased significantly (p < 0.001). Changes in upper lip height and nasolabial angle differed among the groups of the study. While upper lip height increased significantly in groups A and C (p < 0.05), there was a slight decrease in Group B with no significance (p > 0.05). Nasolabial angle decrased significantly on Groups A and B (p < 0.05). The results of this study revealed changes in several soft tissue parameters, some of which occurred regardless of vertical repositioning of the maxilla. Within the limitations of the study, maxillary advancement surgery can affect the aesthetics of the nasolabial region and cause specific changes in related soft tissues. Understanding these changes is essential to establish realistic patient expectations and achieve optimal functional and aesthetic outcomes.

Nasal profile changes after LeFort I osteotomy (maxillary advancement) with and without ANS reduction in class III skeletal patients: a study protocol for a randomized clinical trial. Trials 2024; 25:346. [PMID: 38797838 PMCID: PMC11129358 DOI: 10.1186/s13063-024-08162-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Accepted: 05/07/2024] [Indexed: 05/29/2024] Open
Abstract
BACKGROUND Dentofacial malformation is a common condition that affects a significant portion of the population, resulting in functional and aesthetic defects. Orthognathic surgeries, such as LeFort I osteotomy, are performed to correct these abnormalities. However, the impact of these surgeries on nasal profile changes remains unclear. Additionally, the role of anterior nasal spine (ANS) reduction in maxillary advancement surgeries of 3-5 mm range is yet to be determined. This study aims to investigate the effect of ANS reduction on soft tissue profile changes following LeFort I osteotomy with a maxillary advancement range of 3-5 mm in class III skeletal patients. The hypothesis is that the changes in nasolabial angle and upper lip length will not significantly differ between patients who undergo LeFort I osteotomy with and without ANS reduction. METHOD AND DESIGN This study is designed as a randomized controlled trial. A total of 26 class III skeletal patients with maxillofacial abnormalities will be recruited from the maxillofacial clinic of Bu-Ali and Farahikhtegan Hospitals in Tehran, Iran. Patients meeting the inclusion criteria will be randomly assigned to two groups: one group will undergo LeFort I osteotomy with ANS reduction, and the other group will undergo LeFort I osteotomy without ANS reduction. The soft tissue profile changes, specifically the nasolabial angle and upper lip length, will be evaluated and compared between the two groups. DISCUSSION Achieving facial harmony through orthognathic surgery requires careful planning and consideration of the impact on surrounding soft tissue. The primary objective is to predict and plan for the effects on the nasolabial region. LeFort I osteotomy is a common procedure used to correct dentofacial deformities, particularly in class III patients. Maxillary advancement during this surgery can lead to changes in nasal tip position, width, and rotation, potentially due to repositioning of the anterior nasal spine and soft tissue dissection. In this study, soft tissue changes will be assessed in non-growing class III patients using cephalometric radiographs. The impact of reducing the anterior nasal spine (ANS) on nasal profile changes will be investigated for maxillary advancements of 3-5 mm. Objective measurements and patient-reported outcomes will be evaluated to gain insights into the aesthetic outcomes of orthognathic surgery. The findings will provide valuable guidance for treatment decisions and alternative options based on expected nasal profile changes.

Abstract
Background The safety and outcomes of performing a simultaneous Alar reduction, Lip lift, and Open rhinoplasty Surgery (ALOS) through independent incisions have not been reported in any study, therefore, we aimed to evaluate the safety and outcomes of this combination procedure. Methods This retrospective review study was conducted on all cases of simultaneous ALOS, lip-lift, and alar reduction performed from 2018-2022, at Facial Plastic Surgery Clinic, New York, USA. Alar reduction involved complete through-and-through resection of alar wedge, and the type of lip lift technique was bullhorn design with excision of skin and Superficial Musculo-Aponeurotic System. Primary open rhinoplasty with inverted V-columellar incision was performed. The follow up period ranged between 4 months to 2 years, but all of patients were followed up at 6 days, one, and two months post-operatively. Results Fifty one cases were enrolled. We reviewed criteria of complications including infection, vascular events (such as necrosis, or partial ischemia), and poor scarring, fortunately, we did not have any infection or vascular issues. In 2 cases, columellar scar was "less than optimal", but in all other cases, this scar was "not perceivable" based on the patient survey. In 4 cases, the lip lift procedure scar was considered "less than optimal" showed slight indentation of white scar of lip lift in 9/44 cases. Additionally, all columellar and alar incisions had nearly invisible scarring. Conclusion In primary rhinoplasty cases, without any other surgeries or previous trauma in the oronasal region, performing concomitant lip lift, open rhinoplasty, and alar wedge resection is safe and does not negatively affect vascularity or scarring.

Abstract
BACKGROUND Le Fort I osteotomy is a technique for surgically correcting the maxillary position. Le Fort I osteotomy may affect the nasolabial structures since a very close relationship exists between the maxilla and the nose. PURPOSE This study aimed to investigate the effect of different maxillary movements on the nasal septum after Le Fort I osteotomies with cone beam computed tomography (CBCT) images. We hypothesized that nasal septal angle changes after maxillary impaction and advancement movements. STUDY DESIGN, SETTING, AND SAMPLE This retrospective cohort study involved patients who underwent Le Fort I osteotomy to correct the maxillary position at Erciyes University, Oral and Maxillofacial Surgery Hospital. This study included patients who had CBCT images before (T0) and ≥12 months after (T1) surgery. Patients with a history of septoplasty or rhinoplasty before orthognathic surgery, congenital deformities, or posttraumatic deformities were excluded. PREDICTOR VARIABLES Its predictor variable was the direction and magnitude of the maxilla's vertical and horizontal movements. MAIN OUTCOME VARIABLE Change in septal deviation (in degrees) was the main outcome of the study. COVARIATES Age, sex, operation (Le Fort I alone or double jaw surgery), cartilage reduction, and anterior nasal spine reduction during surgery were covariates. DATA ANALYSIS Angle values were compared with independent samples t test or the Mann-Whitney U test in two-category variables. The Kruskal Wallis test was used to compare the angle values according to the movement. A P value of < .05 was considered statistically significant. RESULTS This study evaluated 154 CBCT images of 77 patients (44 [57.1%] females and 33 [42.9%] males), of which 68 (88.3%) had double jaw surgery and nine (11.7%) had single Le Fort I surgery. The average nasal septum angle was significantly smaller preoperatively (166.2° [157.1° to 172.15°]) than postoperatively (168.7° [131.5° to 180.0°]) across subjects (P = .031). The septal angle decreased in 28 patients, and the rate of postoperative angular change was higher in patients with both advancement and impaction during the surgery (P = .014). CONCLUSION AND RELEVANCE Septum deviation can occur in 37% of cases after Le Fort I surgery. Therefore, Le Fort osteotomies are associated with changes in nasal appearance.

Abstract
PURPOSE Bony changes after orthognathic surgery are always followed by changes of the overlying soft tissues. Therefore, morphologic changes of the nose may be expected after procedures involving the maxilla. The purpose of this study was to evaluate the changes in the nasal region due to orthognathic surgery using computed tomography (CT) images of virtually planned patients. METHODS 35 patients who underwent Le Fort I osteotomy, with or without bilateral sagittal split osteotomy, were included. 3D measurements on preoperative and postoperative images were performed and analyzed. RESULTS The results revealed that aesthetically acceptable results can be achieved by orthognathic surgery alone. CONCLUSIONS According to the results of this study, it can be concluded that it is best to reserve decisions on rhinoplasty to the post-orthognathic period.

Abstract
ABSTRACT The present study aimed to investigate how "Gull in Flight" appearance and alar-columellar relationship change following maxillary surgery. Thirty-three patients who underwent Le Fort I osteotomy with or without mandibular osteotomy were included in this retrospective study. Measurements which were angle of columella triangle, alar-rim angle, columella lobular angle, and distance of points forming "Gull in Flight" appearance were evaluated on pre and postoperative frontal and lateral photos of patients. Data was submitted to statistical analysis and significance level was determined as 0.05. Following Le Fort I surgery, distance of points forming "Gull in Flight" appearance with respect to canthus was decreased significantly (P < 0.05). Positions of these points to each other were not changed (P > 0.05). Every 1 mm maxillary impaction led to 0.58 mm reduction in y3 (the distance from the point that illustrates Gull's body) (P = 0.032). There was a decrease in angle of columella triangle, alar-rim angle and increase in columella lobular angle. However, these changes were not found significant (P > 0.05). Angle of columella triangle was increased 2.51 degree for every 1 mm maxillary advancement (P = 0.028). In conclusion, maxillary surgery had an impact on nasal region from frontal view. However, "Gull in Flight" appearance which is one of the aesthetic parameters in nose was not changed following maxillary surgery.

Abstract
En coup de sabre deformity (ECDS) is a form of localized scleroderma in the frontoparietal region caused by progressive subcutaneous tissue atrophy and bony defect. Although ECDS involves two layers, skin/subcutaneous tissue and bone, the existing literature mainly focuses only on treating the skin/subcutaneous tissue layer. In this case series, we aimed to propose a novel approach that includes the combined use of fat grafting and demineralized bone matrix (DBM). Four patients with ECDS deformity, operated between February 2016 and October 2018, were retrospectively evaluated. All the patients were treated with the novel approach. Patients were evaluated with localized scleroderma scale and computed tomography (CT) scan in the preoperative period and at the annual follow-up. We observed remarkable improvement in the localized scleroderma scale including appearance, palpation, and size scores in all patients at the annual follow-up. CT scans at the annual follow-up revealed new callus formation at the bony defect area in all patients. Reinforcing fat grafting with DBM could promote healing of the bony and skin/subcutaneous tissue defects associated with ECDS.

Abstract
As facial aging occurs, aesthetic changes of the nasal tip and the senile upper lip include tip ptosis, increase in skin length, loss of vermillion height and Cupid's bow, and vertical wrinkles.Regardless of the rejuvenation procedure, the lips are not to be considered as a single anatomical entity, instead they should be placed in a strong correlation with the nose. The aim of this study is therefore to demonstrate the effectiveness of the association of primary closed rhinoplasty together with indirect subnasal lip-lifting technique.A total of 45 patients were enrolled in this study and underwent primary closed rhinoplasty with indirect subnasal lip-lifting. The result showed an overall average nasolabial angle width reduction of 10.9% and lip length shortening of 23.5%, as assessed 1 year after the surgical procedure. When comparing before and after photographs and using the Subjective Global Aesthetic Improvement Scale (sGAIS), the overall satisfaction was rated 4.4 on 5, as "much improved."The authors show that lips should not be considered as a single anatomical entity but that they indeed must be placed in a strong correlation with the nose since a droopy nasal tip is likely to be considered unattractive and is often associated with the appearance of a long nose with covered philtrum and upper lip.Tip rotation to a normal nasolabial angle width could grant a beneficial impact on overall nose aesthetics; however, it may not fully balance the midface profile as it is the "lip position-to-incisal show" ratio that defines beauty, whereas the balance among forehead, nasal tip, upper lip, and chin is what defines the contour of harmonious profiles.This is the first patient series to show that the combination of closed rhinoplasty and indirect lip-lifting is a highly effective, safe, and reliable procedure to address profile rejuvenation.
