“…For instance, the characteristic of the Asian nose is different from the Caucasian nose in several aspects: lower bridge, wide alar width, and different alar-columellar relationships. 3,16 Ideally, nostrils should be symmetrical, and the orientation of each nostril according to columella should be between 45°and 60°. 17 Among morphologic studies classifying nostrils, Farkas' Modified Topinard System, which divides the shape of nostril by angle between the left and right longitudinal axis, is more objective and widely used.…”

Objective: This study aimed to investigate the soft tissue parameters related to inferior nasal morphology and nostril shape and investigate the change at nostril types according to the Modified Topinard System following maxillary surgery. Materials and Methods: Thirty-five patients who underwent Le Fort I osteotomy with or without mandibular osteotomy were included in this retrospective study. Presurgery (T1) and postsurgery (T2) measurements which were the angle between the longitudinal axis of left and right nostril, nostril length, nostril width, alar width, alar base width, columella length, and columella width, were measured on computed tomography images. Nostril types according to Modified Topinard System and nostril shapes were also examined. Results: Following Le Fort I surgery, there was a significant increase in alar base width, alar width, and angle between the longitudinal axis of the left and right nostril (P < 0.05). Nasal tip protrusion was decreased with significance (P = 0.022). Multiple linear regression analysis showed that every 1 mm maxillary impaction amount leads to a 3.34°increase in the angle between the longitudinal axis of the left and right nostrils (P = 0.03, adjusted R 2 = 0.21). Nostril type classification according to Modified Topinard System was changed significantly (P = 0.000). Conclusion: Surgeons should be aware of the risk of postoperative nonaesthetic results in Modified Topinard System's borderline cases. Modified Topinard classification may be included in preoperative orthognathic planning from the bottom view.

Background: 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. Objectives: 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. Methods: 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. Results: 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. Conclusions: 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 of Evidence: Level IV.

“…So far, several techniques have been introduced for nasal sill reduction. Nasal sill excision, with or without alar wedge excision, is a method for decreasing the amount of alar flare and also changing the nostril size, shape, and angle as part of the rhinoplasty procedure [ 5 ]. However, care must be provided during these procedures, as improper resection of the nasal sill soft tissue can result in deformities, such as tear-shaped nostrils [ 6 ].…”

“…On the contrary, nasal sill area augmentation has not received much attention so far, although the use of this technique is quite practical for cases, such as uni/bilateral cleft lip or cleft lip and palate, traumatic lesions, congenital asymmetry of the nostril size, secondary revision surgeries, and reconstruction of defects caused by malignancies (e.g., basal cell carcinoma) [7]. So far, few methods and techniques have been introduced for the nasal sill graft procedure [5,[8][9][10]. Therefore, in this study, we aimed to introduce our novel sill graft technique that can be safely used for most of the aforementioned cases.…”

Background Nasal sill is one of the components of the alar ring, affecting the esthetic outcomes of rhinoplasty; accordingly, we developed a novel technique to adjust defects in this area and compared it with the available techniques. Methods Our technique was based on creating a tunnel access to the nasal sill area through an incision made in the lower third of the columella using the open approach or through a nostril base incision in patients, who underwent alar base reduction, followed by insertion of a cartilaginous graft into the marked defect area. Results A total number of 54 patients with a defect in the nasal sill area were included in this study. Thirty-one patients underwent open rhinoplasty with the sill approach from the lower third of the columella, while 23 patients underwent rhinoplasty with a nostril base approach for nasal sill augmentation procedure. There were no reports of patient dissatisfaction, infection, bleeding, sensory dysfunction, or remaining asymmetry of the sill area. Conclusion Based on the findings of the present study, this technique can be successfully used in reconstructing the nasal sill area with minimal complications and morbidity.
