Powered Micro-saw Versus Conventional Osteotome for Septorhinoplasty: A Prospective, Double-Blind, Comparative Study.

BACKGROUND: Various powered instruments are used to perform osteotomy. A consensus on the best method has not been established due to discrepancies in previous studies. This study aimed to compare the conventional osteotome and a powered micro-saw during septorhinoplasty. METHODS: The single-center, prospective cohort study included 60 patients that were grouped into two groups of 30 each. Group 1 underwent open septorhinoplasty using a conventional osteotome, and group 2 underwent open septorhinoplasty using a powered micro-saw. Postoperative edema, ecchymosis, pain, and nasal blockage were compared between groups. Preoperative and postoperative (6 months) functional and aesthetic outcomes were compared based on FACE-Q, SNOT-22, and T-NOSE scores. RESULTS: There were not any differences in age, gender, follow-up duration, the Brinkman index, or level of education between groups. Postoperative pain scores were significantly lower in group 2 on d 1 and d 3 postsurgery. Nasal blockage scores were significantly higher in group 1 on d 3 and d 7 postsurgery. Edema and ecchymosis scores were similar in both groups at all time points. Preoperative and postoperative (6 months) functional and aesthetic outcomes were also similar in both groups. CONCLUSION: Osteotomy using a powered micro-saw is an effective technique that results in less postoperative pain and nasal blockage than when using conventional osteotome. Early postoperative period edema and ecchymosis scores and long-term functional and aesthetic outcomes are similar when using a powered micro-saw and a conventional osteotome. Osteotomy using a powered micro-saw can be considered an alternative to using a conventional osteotome.

Effects of hyaluronic acid on the bone healing after lateral osteotomy: an experimental animal model.

OBJECTIVE: Postoperative comfort of the patients undergoing rhinoplasty might be poor because of edema and ecchymosis caused by lateral osteotomy. In this animal experiment, we aimed at performing a quantitative assessment of effects of hyaluronic acid usage on healing process of lateral osteotomy. METHODS: Fourteen New Zealand rabbits with a weight of 2000-2500 kg and an age of 8-12 weeks were included. Under anesthesia, nasal dorsums were exposed with midline incision and lateral osteotomies on both sides were performed using a 2 mm chisel. A hyaluronic acid-based mesh (Hyalonect®) (1 × 1 cm) was embedded on the left osteotomy areas of all rabbits. Right osteotomy areas were left blank as control group. Collagen density and capillary development were quantitatively compared. RESULTS: Convergence of fracture lines was observed in 6 (60%) of 10 samples from Hyalonect® group, while was observed in 4 (40%) of 10 samples from control group. Although a higher rate of convergence was seen in the Hyalonect® group (60% vs 40%), the difference was not statistically significant (p = 0.5). Median collagen score was 2 (1-3) in the Hyalonect® group and 1 (1-2) in the control group. Median capillary count value was 4 (1-23) in the Hyalonect® group and 3 (1-17) in the control group. Both collagen score and capillary count values were significantly greater in the in the Hyalonect® group compared with the control group (p = 0.023 and p = 0.019, respectively). CONCLUSION: The effects of hyaluronic acid-based meshes on the bone healing process of the lateral osteotomy area might be investigated furthermore, on more comprehensive studies, as a material facilitating collagen organization and capillary development.

How can periorbital oedema and ecchymose be reduced in rhinoplasty?

Oedema and ecchymose are frequent morbidities of septorhinoplasty, a facial surgical procedure for reforming the shape and functions of the nose. Periorbital oedema (PO) and periorbital ecchymose (PE) are normal occurrences, but are undesirable for patients undergoing the procedure for aesthetic purposes. The present study examined 65 patients who underwent open technique septorhinoplasty for aesthetic and functional complaints. Patients were divided into two groups: Group 1 patients underwent lateral osteotomy following tip plasty, at the end of the surgical operation; Group 2 patients underwent lateral osteotomy before tip plasty, at the beginning of the surgical operation. Patients were followed on the postoperative first, third and seventh days. PO and PE values of patients were scored from 0 to 4. The plastering time (Pt) was significantly shorter for Group I than Group II (p < 0.05). The total surgical time (T) showed no significant difference (p > 0.05). The PO value at the first, third and seventh days was significantly smaller for Group I than Group II (p < 0.05). The PE value at the first, third and seventh days was also significantly smaller for Group I than Group II (p < 0.05). The obtained data indicate that performing a lateral osteotomy in the final stages of surgery, and subsequently applying a nasal plaster and splint as rapidly as possible, decreases PO and PE in the postoperative period.

[Osteotomies in rhinoplasty]. / Ostéotomies en rhinoplastie.

Osteotomies are performed to modify the shape of the bony part of the nose, therefore they should not be done systematically. Main indications are correction of deviated nose, narrowing of bony vault and roofing of an open roof after important hump resection. The nose should be very precisely analyzed before osteotomies if the surgeon doesn't want to create deformities such as step, inverted V, pinched nose or saddle nose. When too narrowed, bones can also block the airway and lead to functional problems.

Comparison of the Effect of Two Low to High Lateral Osteotomy Methods, Percutaneous and Internal On the Tear Trough and Scleral Show in Patients Undergoing Esthetic Open Rhinoplasty.

Background: We aimed to compare the effect of two low to high lateral osteotomy methods, percutaneous and internal on the tear trough and scleral show in patients undergoing esthetic open rhinoplasty. Methods: This prospective single-blind randomized clinical trial study was conducted on 80 patients in two groups of 40 candidates for rhinoplasty surgery referred to Imam Khomeini Hospital in Ahvaz, southern Iran in 2021. In the first group, lateral osteotomy was performed internally and in the other group, percutaneously. Then, the changes in tear trough and scleral show before surgery, one and three months after surgery were compared between two groups. Results: The median of the medial limbus in the percutaneous group was about 0.38 higher than the internal group, but no significant difference was observed (P=0.322). Moreover, the median medial canthus in the percutaneous group compared to the internal group had no statistically significant difference (P=0.163). There was no significant difference in the average lateral limbus changes between the two groups (P=0.389). The median scleral show in all times before surgery, one and three months after surgery in the percutaneous group was higher than in the internal group, but the differences were not significant. In addition, the median scleral show changes before and three months after surgery in the percutaneous group were not remarkably different from the internal group (P=0.290). Conclusion: Both techniques are almost similar in terms of periorbital effect after surgery in the early stages and 3 months after surgery. More multicenter studies with higher sample size and longer follow-up period seem necessary.

Efficiency-Efficacy Assessment of External Lateral Osteotomy Technique Versus Internal One in the Rhinoplasty.

In this study we aimed to compare external lateral osteotomy technique vs. internal one in the rhinoplasty. In this before-after clinical trial study 30 patients who were candidates for rhinoplasty involved. In each patient, external lateral osteotomy was performed on one side and internal lateral osteotomy was performed on the other side randomly. Information, including patients' age, sex, grade of edema and ecchymosis 1, 3, and 7 days after the surgery, and the type of lateral osteotomy, the amount of step deformity, the need for the specialist intervention, nasal bone mobility, and flail nasal bone was recorded and analyzed. The incidence of edema and ecchymosis on the first and the third day was statistically lower in the external method (P value < 0.001). Although the incidence of edema and ecchymosis on the seventh day was lower in the external method, it was not statistically significant (P value > 0.05). Forty seven percent of patients in the internal method and 36% of patients in the external method had step deformity (p value < 0.001). Fifty percent of patients in the internal method and 41% of patients in the external method needed the specialist intervention (p value > 0.05). Seventy four of patients in the internal method and 83% of patients in the external method had nasal bone mobility (p value > 0.05). Out of 30 patients, only one had flail nasal bone. Based on our findings, the external technique is suggested as a more effective and convenient method with less complications for inexperienced surgeons.

Navigated Lateral Osteotomy for Adult Spinal Deformity: A Technical Note.

BACKGROUND: Minimally invasive surgery is receiving considerable attention as a technique for reducing the complications of adult spinal deformity (ASD) surgery. For this technique, a new lateral osteotomy plays an important role to release fused vertebrae. We describe herein a novel navigated lateral osteotomy technique not requiring C-arm fluoroscopy to correct adult spinal deformities. CASE DESCRIPTION: A 68-year-old woman with symptomatic ASD and a 4-year history of severe low back pain affecting daily life was referred to our hospital. Surgery was performed without C-arm fluoroscopy. A navigated osteotome was used to release the fused L1/2 mass. The patient was successfully treated with surgery, and low back pain was well controlled. In terms of clinical outcomes, Oswestry Disability Index improved from 64%-19% and Visual Analog Scale score for low back pain improved from 74 mm-19 mm on final follow-up at 2 years. CONCLUSIONS: This novel navigated lateral osteotomy for ASD is a useful technique that enables minimally invasive surgery for fixed deformity. With this new technique, surgeons and operating room staff can avoid adverse effects of intraoperative radiation.

Method of Lateral Osteotomy to Reduce Eyelid Edema and Ecchymosis After Rhinoplasty: A Meta-analysis.

OBJECTIVES: Although lateral osteotomy is an important part of rhinoplasty, it is known to be closely associated with postoperative eyelid edema and ecchymosis after rhinoplasty. There is no consensus on which osteotomy methods are effective in reducing morbidity from rhinoplasty. This study compared the effects of different osteotomy methods on edema and ecchymosis after lateral osteotomy using a meta-analysis. STUDY DESIGN: A literature search using MEDLINE, SCOPUS, and Cochrane databases. METHODS: Two authors independently reviewed the databases published until May 2019. Randomized controlled trials that compared lateral osteotomy methods (external approach) with different methods (internal approach), for which the outcomes of interest were mucosal injury, edema, and ecchymosis on postoperative days, were included. Sufficient data for meta-analysis was found in six studies with a total of 224 patients. RESULTS: In a comparison of the external approach with the internal approach, mucosal injury was significantly lower in the external approach (odds ratio = 0.41; 95% confidence interval = [0.11; 0.99], I2 = 29%). There were significant differences between the external and internal approach in eyelid ecchymosis and edema, except for eyelid ecchymosis at 7 days postoperatively. However, all significant results showed a small effect size with a standardized mean difference near 0.2. CONCLUSIONS: The external approach during lateral osteotomy had no significant advantage in edema and ecchymosis compared to the internal approach. Further studies with good research methodology should be carried out to determine the effect on the postoperative complications of different lateral osteotomy methods. Laryngoscope, 131:54-58, 2021.

Objective Outcomes in Lateral Osteotomy Through Anterior-to-Psoas for Severe Adult Degenerative Spine Deformity Correction.

Multilevel lateral interbody fusion is an acceptable surgical technique in patients with severe degenerative adult spinal deformity (ASD). The current standard-of-care in spine surgery includes the use of patient reported outcome measures (PROMs) to assess post-operative improvement. Objective activity data during the peri-operative period may provide supplementary information for patients recovering from ASD surgery. In this report, we use smartphone-based activity data as an objective outcome measure for a patient who underwent a two-stage operation for ASD corrective surgery: lateral osteotomy and lumbar interbody fusion with posterior column release. An 82-year-old male presented with intractable back pain secondary to severe thoracolumbar scoliotic deformity (Lenke 5BN). Pre-operative images demonstrated the presence of bridging osteophytes over the left lateral aspect of L2-5 disc spaces and over the apex of the lumbar curvature, with significant neuroforaminal stenosis. Surgical correction was completed in two stages: (1) left-sided lateral osteotomy using anterior-to-psoas approach (ATP) in a right lateral decubitus position, and (2) multilevel Ponte osteotomies and instrumented fusion from T10-pelvis. Post-operative radiography showed correction to scoliotic deformity and sagittal misalignment. The patient had developed seroma and wound dehiscence, which was evacuated on post-operative day 11. At 14-month follow-up, the patient reported significant improvement in pain symptoms, corroborated by patient reported outcome measures. To further quantify and assess patient recovery, smartphone-based patient activity data was collected and analyzed to serve as a proxy for the patient's functional improvement. The patient's walking steps-per-day was compared pre- and post-operatively. The patient's pre-operative baseline was 223 steps/day; the patient's activity during immediate post-operative recovery dropped to 179 steps/day; the patient returned to baseline activity levels approximately 3 months after surgery, reaching an average of 216 steps/day. In conclusion, we found that lateral osteotomy through an ATP approach is a powerful tool to restore normal spine alignment and can be successfully performed using anatomic landmarks. Additionally, smartphone-based mobility data can assess pre-operative activity level and allow for remote patient monitoring beyond routine follow-up schedule.

Investigation of the Effects of Internal and External Lateral Osteotomies on Periorbital Edema and Ecchymosis in Patients Undergoing a Septorhinoplasty.

OBJECTIVE: Periorbital ecchymosis and edema are common after septorhinoplasty surgery. This study aimed to compare internal and external lateral nasal osteotomies performed in septorhinoplasty in terms of postoperative ecchymosis and edema. METHODS: Patients who underwent septorhinoplasty between January 2020 and July 2020 in our clinic were included in the study. In all patients, right lateral nasal osteotomies were performed endonasally and left lateral nasal osteotomies externally. The postoperative 1st, 7th, and 14th day ecchymosis and edema scores of all patients were calculated separately for the two groups and compared. RESULTS: A total of 60 patients (29 females, 31 males) were included in the study. The mean age of the patients was 33.88 ± 10.30 years. No significant difference was observed between the two groups in terms of the postoperative periorbital ecchymosis scores on the first day and the first and second weeks (0.314, 0.344, and 0.468, respectively). There was also no significant difference between the two groups in terms of the postoperative periorbital edema scores on the first day and at the first and second weeks (0.272, 0.359, and 0.513, respectively). CONCLUSION: The results obtained from this study showed no significant difference in the periorbital ecchymosis and edema scores between the patients who had undergone septorhinoplasty with internal or external lateral osteotomies. Further multicenter studies are recommended to verify the findings of this study with a larger sample size.

A New Instrument For Rhinoplasty: The Osteotom With Lighting Guide Transilluminating Osteotomy.

Rhinoplasty remains one of the most commonly performed aesthetic surgical procedure that demands a meticulous intraoperative precision as well as maximum precaution and control. Nasal osteotomy is a key component to shape the bony vault in aesthetic rhinoplasty, but it is also the so versatile, dangerous, and difficult to learn. The present study aims to evaluate the usefulness of our locator instrument for beginners which is called transilluminating osteotome. The use of transilluminating osteotome instead of guided lateral nasal osteotome is a reliable instrument since it facilitates the localization of osteotome and osteotomy line beneath the soft tissue with a limited damage to the surrounding soft tissues. Level of Evidence: III.

Radiological assessment of the lateral osteotomy line-lacrimal system distance on three-dimensional models.

AIMS: One of the most commonly performed operations in aesthetic, plastic, and reconstructive surgery is rhinoplasty, the aim of which is to construct an altered nasal shape, either for aesthetic or functional reasons. The lateral osteotomy is the most traumatic step of rhinoplasty, and is generally difficult to perform. The lacrimal system can be damaged during the lateral osteotomy procedure. In this study, we aimed to measure the distance between the lacrimal system and the lateral osteotomy line, and to determine the safe and ideal osteotomy level, which is very important in rhinoplasty procedures. We also evaluated the safe relationship of this osteotomy level with the lacrimal system by constructing a three-dimensional model. MATERIALS AND METHODS: The three-dimensional models were constructed on axial planes using paranasal computed tomographic (CT) images of 40 male and 40 female patients. The 'lateral osteotomy model' was designed in three dimensions. The axial CT images were obtained from the model. On the CT images, the distance between the lateral osteotomy line and the lacrimal system was assessed by measuring three distances. The first was the distance between the anterior lacrimal crest and the lateral osteotomy line. The second was the distance from the midpoint between the anterior lacrimal crest and the inferior meatus to the lateral osteotomy line. The third was the distance between the opening of the lacrimal canal to the inferior meatus and the lateral osteotomy line. RESULTS: No lacrimal system injury was seen on any of the models. The shortest distance was found between the anterior lacrimal crest and the lateral osteotomy line, measured at 4.5 mm and 5.0 mm in the female and male patients, respectively. CONCLUSION: Performing the lateral osteotomy meticulously while paying attention to remaining anterior to the medial canthal ligament will not lead to any lacrimal system injury.

Intra-operative nasal compression after lateral osteotomy to minimize post-operative Peri-orbital ecchymosis and edema.

INTRODUCTION: Post-operative periorbital ecchymosis and edema following rhinoplasty is a well-known sequela of surgery. Unfortunately, this can be a source of distress for patients, resulting in a longer post-operative recovery time and a delayed return to work. Trauma caused by lateral osteotomies is likely the most significant cause of periorbital edema and ecchymosis in rhinoplasty. There have been various strategies proposed to minimize swelling and ecchymosis with varying success rates and accompanied risks. Intraoperative nasal compression is one potential strategy that may reduce post-operative edema and ecchymosis with minimal risk. OBJECTIVE: To determine whether applying direct lateral nasal pressure intraoperatively immediately after performing lateral osteotomies reduces visible post-operative edema and ecchymosis. METHODS: A prospective, randomized blinded study on consecutive patients undergoing rhinoplasty with lateral osteotomies was conducted in a single academic tertiary care medical center. Each of the participants were randomized into direct pressure application post-lateral osteotomies on the right or the left hand side. Intra-operatively, direct lateral nasal pressure was performed on the pre-determined side for 5 min timed by stopwatch after osteotomy. Post-operatively, standard photographs were taken of the patient on post-operative days 1, 3, and 7. These photographs were then shown to 20 blinded-physicians and the degree of ecchymosis and edema was graded using a previously published scale. RESULTS: A total of 16 patients were included in this study. Based on our blinded-grading, 11 of the 16 patients had a clear global improvement in the degree of peri-orbital post-operative edema and ecchymosis with compression post lateral osteotomies. Based on the 3 blinded expert reviewers, Periorbital ecchymosis was significantly decreased on the ipsilateral side of pressure application in 10 of the 16 patients, and periorbital edema was significantly decreased in 13 of the 16 patients. The differential degree in periorbital ecchymosis was most pronounced on post-operative day 7. Patient factors such as gender, age, skin color, history of nasal trauma, side of pre-operative nasal deviation, and smoking status did not have a significant influence on the effect of pressure application post lateral osteotomies. CONCLUSIONS: Application of direct continual lateral nasal pressure intraoperatively after performing lateral osteotomies can help reduce post-operative edema and ecchymosis up to post-operative day 7. This may lead to an overall improved appearance and subsequently an improved post-operative experience for the patient. Although the effect may be variable to some degree, this is an intervention with no additional risks involved and thus can be used in a safe manner.

Use Of Steroids In Rhinoplasty With Lateral Osteotomies For Reducing Post Operative Oedema.

BACKGROUND: TPostoperative periorbital oedema is a commonly encountered side effect of rhinoplasties in which lateral osteotomies have been incorporated. It dissatisfies the surgeon as well as the patient. Osteotomies are done at the end of all soft tissue manipulation to reduce the development of oedema. The aim of this study was to determine the efficacy of intravenous dexamethasone in reducing oedema in patients who undergo rhinoplasty with lateral osteotomies. METHODS: A Prospective randomized controlled trial was done at department of plastic and reconstructive surgery, Shifa International Hospital Islamabad. Sixty patients age between 16-55 requiring open rhinoplasty were taken for this study and divided in two groups. One group received dexamethasone 8mg intravenously preoperatively and second dose 4 hours postoperatively. The second group did not receive anything. Both groups were assessed on first post-operative day and 7th day for periorbital oedema. RESULTS: The overall decrease in oedema in patients who received steroid was by 50% while in control group was 33.3%. By the 7th day control group 13.3% patients had grade III oedema as compared to 3.33% in steroid group. Chi test was applied and p-value of 0.0289 was obtained which was found to be statistically very significant. CONCLUSIONS: Dexamethasone used in minimal dosage showed significant advantage in reducing periorbital oedema after rhinoplasty with no evidence of any side effects secondary to steroid administration.

Results of intravenous steroid injection on reduction of postoperative edema in rhinoplasty.

OBJECTIVE: To determine the efficacy of intravenous dexamethasone in reducing postrhinoplasty edema. DESIGN: A prospective, randomized clinical trial with placebo control. SETTING: Department of Otorhinolaryngology, Al-Sabah and Zain Hospital, Kuwait. SUBJECT: Eighty-four patients (male = 28; female = 56) aged between 20 and 40 years, undergoing open rhinoplasty with hump removal and bilateral lateral osteotomies were enrolled in this study. INTERVENTION: Patients were randomized to receive two doses of 10 mg of dexamethasone intravenously or placebo, first dose during surgery and second dose 12 hours after surgery. MAIN OUTCOME MEASURES: Patients were evaluated postoperatively at 24 hours, days 2, 5, 7 and 10 for periorbital edema. RESULTS: 10 mg of dexamethasone given intravenously during rhinoplasty and a second dose 12 hours after surgery, reduced postoperative periorbital edema significantly. CONCLUSION: This study showed a statistically significant benefit of dexamethasone over placebo in reducing periorbital edema after rhinoplasty. No complications were attributed to the administration of dexamethasone.

External vs. internal osteotomy in rhinoplasty.

BACKGROUND: The aim of study is to compare the external osteotomy vs. internal osteotomy in patients undergoing rhinoplasty. METHODS: The study group comprised of 45 patients that had undergone rhinoplasty surgery. The 25 patients had undergone internal / endonasal continuous lateral osteotomy and 20 patients had undergone external / percutaneous perforating digital osteotomy. The internal osteotomy was done high to low to high using 4 mm. curved guarded osteotome. The external osteotomy was done by 2 mm sharp osteotome. The scoring system of Kara and Gokalan was followed for edema and ecchymosis. CONCLUSION: External osteotomy is an easy approach to carryout and makes fracture with high precision along preset lines. The bone stump is stable. The damage to the nasal mucosa is much less. There is reduced bleeding, reduced edema and reduced ecchymosis around eyes. The cutaneous scar at the entry site of osteotome is invisible.
