Current updates in nasal bone reshaping

Precision Rhinoplasty Cylindric Burrs-Sidewall Aesthetics

The development of power instruments has led to great advances in rhinoplasty. It has helped to reduce operating time, minimize damage to the surrounding soft tissues, and allow precision bony modification compared with the use of manual rasps. Burrs help ensure precise results by (i) creating a smooth transition between the lateral nasal sidewall and the face, (ii) treating bony asymmetries, and (iii) producing homogeneous upper and middle thirds that softy translate into the upper lateral cartilages. The aim of this paper is to show applications of cylindrical burrs in rhinoplasty surgery to treat the dorsal upper and middle thirds as well as lateral sidewalls of the nose, regardless of whether the dorsal preservation or structure technique is used. This approach offers a safe, fast, and precise technique that can be used in conjunction with piezo osteotomy to obtain the optimal outcomes.

Double Lateral Osteotomy: Not Only the Correction of Crooked Noses but a Relevant Aesthetical Refinement in Structural Rhinoplasty

BACKGROUND

Osteotomy represents a crucial step in structural rhinoplasty; however, there is not a unique approach accepted. Double lateral osteotomy has proven to be effective in the long-term correction of a deviated nose. In this series, we evaluated its aesthetic value also in non-deviated cases.

MATERIALS AND METHODS

864 patients who underwent primary structural rhinoplasty from 2012 to 2020 were divided into four groups. Group A and B included patients with a crooked nose treated with asymmetrical double osteotomy and bilateral double osteotomy, respectively. Patients who did not present nasal deviation were divided into group C, including cases treated with bilateral single osteotomy, and group D, including patients who underwent bilateral double osteotomy. Postoperative evaluations were performed by three independent plastic surgeons blinded to the surgical technique. Patient's satisfaction was assessed through the FACE-Q rhinoplasty module.

RESULTS

FACE-Q scores reported a satisfaction rate higher than 30% for every item in all groups; however, group B and group D showed statistically higher satisfaction (p < 0.01). According to the evaluations performed by physicians, group B and group D showed the most satisfactory outcomes (p < 0.01).

CONCLUSIONS

bilateral double osteotomies represent a significant aesthetic refinement in structural rhinoplasty, not only in crooked noses but also in non-deviated cases, since the reduction in the width of the nose is an aesthetical aspect very appreciated by patients.

Surgical Burr-Assisted Lateral Osteotomy Technique in Septorhinoplasty

ABSTRACT

Achieving aesthetic and functional results in rhinoplasty requires meticulous techniques, and postoperative edema, ecchymosis, and pain can deteriorate the desired outcomes. Different osteotomy techniques are defined to have optimal outcomes while reducing edema, ecchymosis, and pain. In this study, the authors compared conventional and power-assisted surgical burr osteotomy techniques in terms of early postoperative complications. Patients who underwent primary open septorhinoplasty were included in the study and were divided into 2 groups. The first group had lateral endonasal osteotomy with conventional guided osteotomes, and the second group had lateral osteotomy with surgical round burr. Edema and ecchymosis scoring systems were used on the postoperative first, third, and seventh day to evaluate postoperative edema and ecchymosis, and the visual analog scale was used to evaluate pain severity on the postoperative period. Out of 70 patients who had undergone septorhinoplasty, 36 received conventional osteotomy and 34 received surgical round burr osteotomy. Periorbital ecchymosis scores were significantly lower in the second group on the postoperative first, third, and seventh days. The periorbital edema scores were significantly lower in the second group on the first postoperative day but no difference was found between postoperative days 3 and 7. Also, the pain scores were significantly lower in the second group. Osteotomy with surgical round burr yields less ecchymosis, edema, and pain in the early postoperative period than conventional osteotomy in primary septorhinoplasty patients.

Computer-Aided Rhinoplasty Using a Novel "navigated" Nasal Osteotomy Technique: A Pilot Study

OBJECTIVE

To describe the surgical technique of navigation-guided nasal osteotomies and assess feasibility of this technique for treating complex nasal bone deformities in reconstructive rhinoplasty.

METHODS

A retrospective chart review was performed in order to identify patients who underwent computer-aided rhinoplasty from August 2014 to February 2017. Inclusion criteria were nasal bone deformities on computed-tomography (CT) that correlated with specific nasal complaints. All patients underwent computer-aided rhinoplasty with navigation-guided nasal osteotomies using a standard navigation system. Osteotomies were performed using real-time visualization on the navigation screen. Additional soft tissue procedures were performed as needed. Medical records were reviewed for presenting symptoms, radiologic and operative findings, and postoperative course. Cosmetic outcomes were subjectively based on patients' standard 6-view photo-documentation from pre- and post-operative timepoints.

RESULTS

Twenty-one patients were included in the study; 8 were revision cases and 3 had mild-to-moderate hemifacial microsomia. Fifteen were completely closed procedures. No cases were opened because of inadequate visualization or difficulty accessing bony pathology. Mean (range) follow up was 98.6 (6-559) days. There were no intra-operative complications, unplanned admissions or re-admissions, or iatrogenic cosmetic complications (ie, "inverted V" or "saddle nose" deformities). Two patients required revision. One was after suffering nasal trauma within 4 weeks of initial rhinoplasty. The second underwent further correction of a deformity that required a costochondral graft. Both experienced good final results.

CONCLUSIONS

Computer-aided rhinoplasty is safe and feasible for treating complex nasal deformities using standard navigation systems.

Osteotomies Demystified

Osteotomies are critical techniques in rhinoplasty. There are a variety of approaches, trajectories, and tools used with no widely standardized classification or nomenclature. Percutaneous osteotomies are gaining in popularity, and picture framing the nasomaxillary bone is crucial for predictable fracture and reproducible results. This is best accomplished with medial, lateral, and transverse osteotomies. Intermediate osteotomies are used less frequently, but provide more mobility. With a detailed understanding of anatomy and a thorough approach to nasal osteotomies, the contour and function of the bony vault can be reshaped with a successful outcome for both the surgeon and patient.
