Minimally Invasive Secondary Rhinoplasty In Over-Resected Noses Without Rib Grafts
Denizhan Dizdar, Mohsen Naraghi

Cartilage is the most necessary material for grafting in secondary rhinoplasty cases with over-resection, addressing multiple structural and surface defects. However, selecting the ideal graft has been a concern due to donor site morbidity and potential issues like graft visibility, irregularities, infection, and inflammatory reactions. Advances in facial plastic surgery have led to the development of special techniques to reduce donor site morbidity using autografts. By combining open and endoscopic approaches, we can provide sufficient support for structural and camouflage purposes exclusively using non-rib sources, resulting in minimal morbidity and successful outcomes.

Chin Augmentation By Fillers Versus Surgery
Denizhan Dizdar, Mohsen Naraghi

The chin is in a prominent position on the face and plays a significant role in the facial profile. Advancement osteotomy or filler augmentation could be performed during facial procedures to improve the facial profile. In surgical cases, after horizontal osteotomy was completed, five different fixation methods were applied using mini-plates and screws. In the patients who did not tend to undergo surgical intervention, fillers were used as a simple method with no or very minimal risk. However, it is suitable for mild to moderate cases with no functional problems.

Modern Concepts Of The Complex Anatomy Of The Nose And Its Significance In Rhinoplasty
Denizhan Dizdar, Melih Güven Güvenç, Arzu-Almaz Mashurov
Introduction

modern rhinoplasty requires a profound understanding of the complex anatomy of the nose, including the interaction of bony, cartilaginous, and soft tissue structures. The evolution of surgical approaches aims to preserve airway functionality while achieving an aesthetically harmonious outcome.

objective

to analyze current concepts of the complex nasal anatomy and its influence on rhinoplasty techniques aimed at improving both aesthetics and functionality.

materials and methods

the study is based on the analysis of anatomical data, clinical observations, and a comparative evaluation of surgical techniques. Computed tomography, 3d modeling, and statistical data processing were employed for patients who underwent rhinoplasty. The study included 50 participants (30 women and 20 men) who underwent rhinoplasty for aesthetic and functional indications between january 2024 and february 2025.

patient examinations were performed preoperatively, and subsequently at 1, 3 months, and 1 year postoperatively. The assessment included patient complaints and medical history, laboratory tests according to nosological standards, standard ENT examination, specific functional nasal valve tests (“push-up” test, cotton ball test, cottle maneuver) and endoscopic evaluation of the nasal cavity. Statistical analysis was performed using IBM SPSS statistics software.

results

analysis of 50 rhinoplasty cases revealed that nasal anatomical features play a key role in determining the surgical technique and predicting outcomes. The main findings include:

1.       individual anatomical variations.

72% of patients demonstrated anatomical characteristics that influenced preoperative planning and surgical techniques. The most significant variations included:

• variability in the shape and thickness of the osteocartilaginous framework.

• differences in the angle of nasal septal deviation.

• various attachment types of the medial crura of the alar cartilages.

• variations in the structure of the lateral cartilages affecting airway patency.

• differences in subcutaneous fat layer thickness determining contour modeling complexity.

key external nasal features in the kazakh population include:

• thick nasal tip skin with a pronounced subcutaneous fat layer.

• low and wide dorsum with a poorly defined cartilaginous hump.

• broad nasal tip.

• hypoprojection of the tip.

• wide alar base.

• closed v-shaped nostril type.

2.       influence of anatomical features on surgical techniques.

in 85% of cases, surgeons emphasized the importance of considering individual anatomy to achieve optimal outcomes. Analysis of surgical procedures identified the following challenging zones:

• osteocartilaginous junction of the nasal dorsum – high risk of deformities during resection.

• alar cartilages – critical for maintaining the aesthetic form of the nasal tip.

• nasal septum – its condition determines the possibility of complete functional correction.

• soft tissue thickness – patients with thick skin present greater difficulty in achieving a well-defined contour.

conclusion

rhinoplasty based on detailed study of nasal anatomy allows minimization of postoperative complications and improvement in the predictability of aesthetic outcomes. Modern technologies, including 3d analysis and computer modeling, contribute to increased precision in surgical interventions.

Facial Assymmety And Its Impact On Rhinoplasty Results
Denizhan Dizdar, Melih Güven Güvenç

Description: rhinoplasty surgeons often find that despit their best efforts to straighten the nose, patients ofte continue to perceive their nose as deviated, and this perception is particularly prevalent in patients with concurren facial asymmetry. We can do a 7 minutes presentation on this topic

outcome objectives: we want to raise awarenes about the facial assymmetry before rhinoplasty

backgorund: this subject has been published as a paper: awareness of facial asymmetry and its impact on postoperativ satisfaction of rhinoplasty patientawareness of facial asymmetry and its impact on postoperativ satisfaction of rhinoplasty patient

Advances In Otoplasty: Techniques, Outcomes, And Future Directions
Denizhan Dizdar, Mehmet Murat Günay, KÜBRA TOPAL

Otoplasty remains a cornerstone of aesthetic and reconstructive ear surgery, primarily addressing congenital deformities such as prominent ears. Over time, the field has evolved beyond purely cosmetic goals to encompass functional and psychological considerations, especially in pediatric and adolescent populations. Despite advancements in technique, a subset of patients—estimated at up to 15%—continues to experience suboptimal outcomes, including asymmetry, recurrence, or dissatisfaction with aesthetic results.

in this presentation, we aim to share our surgical technique and clinical outcomes from a series of over 100 patients treated at ankara etlik city hospital. Our method focuses on enhancing surgical precision, improving reproducibility, and minimizing complications through a refined approach to cartilage reshaping and suture placement.

the objective of this session is to:

  1. present a step-by-step overview of our technique.

  2. analyze complication rates and identify key risk factors.

  3. discuss strategies to optimize patient satisfaction and long-term aesthetic outcomes.

our clinical data demonstrate a satisfaction rate exceeding 95%, supporting the effectiveness and reliability of our approach. This presentation builds upon previous research and clinical experience to propose a standardized technique that may contribute to improved global outcomes in otoplasty.

Indirect Lip Lift Surgery Video
Denizhan Dizdar, KÜBRA TOPAL

A technical variant of the gull-wing lip lift is the sub-nasal lip lift (bull-horn lip lift), which involves the removal of either an ellipse or a curved-edge ellipse of tissue from under the nose. The skin then is raised, and sutured to lift the lip and expose more of the upper-lip vermilion.Depending upon the indications of the patient, this technique can increase the drooping the corners of the mouth (commissures); thus, the sub-nasal lip lift often includes a corner-lift surgical step. in the corner lift procedure, triangles of tissue are resected from above the commissures, thereby elevating the corners of the mouth.A descending wedge of tissue can also be removed to add contour to the cupid's bow or to reduce bulky lips.
