Operative treatment and postoperative complications of a frontal sinus fracture: a case report

Frontal sinus fractures are significant injuries; they represent approximately 5-15% of all maxillofacial trauma cases. These fractures can cause complications and present important challenges. The type of surgical technique used, such as sinus reconstruction or obliteration, depends on the severity of the trauma and the general condition of the patient. The surgical treatment for frontal sinus fractures may include a coronal approach. The outcomes associated with frontal sinus fractures can range from mild headaches to severe complications, including cerebrospinal fluid (CSF) leakage; in cases of ineffective conservative treatment, surgical intervention may be necessary. TachoSil is used as a sealing agent during surgery to mitigate potential complications.

026. Utilizing Pre-Existing Lacerations for Frontal Bone Fracture Management: A Case Report

Background: Patients with fractures of the frontal bone use the coronal incision approach to expose the anterior cranial vault, including the forehead. The flap allows for widespread exposure of the fractures, facilitating access for the removal of segmental fractures and hematoma evacuation. Maintaining sufficient pedicle width is crucial to reduce the risk of unintentional arterial damage and to ensure proper venous drainage. The objective of this study was to document the surgical approach for segmental fracture removal under a forehead pedicle flap. Case: This case presents a 22-year-old male with moderate traumatic brain injury, who had two lacerations on his forehead and showed an open depressed fracture of the frontal bone after a motor vehicle collision. The patient experienced loss of consciousness and a history of vomiting. Imaging revealed intracerebral hemorrhage in the frontal region and a depressed fracture of the frontal bone. Intraoperative findings revealed the fracture site through the previous laceration incision. The fracture was clearly evaluated by the surgeon using tools to lift the skin between the two incisions. Conclusion: Despite the access for segment fracture removal being conducted through a pre-existing laceration, the patient outcomes were favorable, and no complications were reported.

Three-dimensional secondary reconstruction of mistreated zygomatic fractures using patient specific surgical guides and implants.

The zygomatic bone has a great impact on the anterior and lateral projection of the midface as well as the proper position of the globe. Primary alignment of zygomatic fractures is very important as secondary reconstruction is far more challenging. Treatment of misaligned zygoma requires refracturing of the bone to allow for repositioning. Due to the great impact of the zygoma on the projection of the midface, a precise 3D realignment is of great importance. Technology nowadays develops rapidly and allows for superior results in many surgical fields. The use of patient specific surgical guides and fixation plates is becoming more abundant. Using 3D segmentation and design software, we developed a sequence for using 3D planning and printing both for the refracturing stage, avoiding a coronal approach, and for precise repositioning and fixation of the zygoma in the new position. The method is described as well as a unique advanced 3D analysis, allowing for objectively assessing the results. Two cases are presented, including the design and post operative changes. Pre-op, planned and final positions were compared and showed exceptional accuracy allowing for the elimination of human errors which are common in a 3D sensitive procedure such as refracturing of the zygoma. This method can easily be applied to other secondary reconstruction procedures requiring realignment.

Coronal Approach (Cadaver)

For treatment of facial trauma such as a frontal sinus fracture, orbital fractures, or zygoma fractures, the coronal or bi-temporal approach is used. The approach can also be used for superficial temporal artery biopsy. This approach exposes the anterior cranial vault, forehead, and upper and middle regions of the facial skeleton including the zygomatic arch. It provides access to these areas with minimal complications and cosmetically acceptable hidden scars. The subperiosteal or subgaleal planes are commonly used for coronal flap dissection. Here, we present a demonstration of the coronal approach to exposing the upper or middle facial skeleton in a cadaver.

Based on CT imaging, surgical approach selection for frontal and ethmoid sinus osteoma

Objective:To investigate the criteria for selecting surgical approaches for frontal and ethmoid sinus osteomas of different locations and sizes on CT imaging. Methods:Using sagittal and coronal CT images, the following lines were delineated: the F-line（a horizontal line passing nasofrontal beak）, the M-line（a vertical line passing paries medialis orbitae）, and the P-line（a vertical line passing the center of the pupil）. Classification of frontal and ethmoid sinus osteomas was based on their relationship with these lines. Appropriate surgical approaches were selected, including pure endoscopic approaches, endoscopic combined with eyebrow incision approach, and endoscopic combined with coronal incision approach. This method was applied to a single center at the Third Affiliated Hospital of Sun Yat-sen University for endoscopic resection of frontal and ethmoid sinus osteoma. Case Data: Sixteen cases of ethmoid sinus osteomas were treated from January 2020 to September 2023. Among these cases, there were 9 males and 7 females, with ages ranging from 18 to 69 years, and a median age of 48 years. Results:Thirteen cases underwent pure endoscopic resection of the osteoma, while in three cases, a combined approach was utilized. Among the combined approach cases, two exceeded both the M-line and the F-line but did not cross the P-line; therefore, they underwent endoscopic combined with eyebrow incision approach. One case exceeded all three lines and thus underwent endoscopic combined with coronal incision. In all cases, complete resection of the osteoma was achieved as per preoperative planning, and none of the patients experienced significant postoperative complications. Conclusion:For frontal and ethmoid sinus osteomas, it is advisable to perform a thorough preoperative radiological assessment. Based on the size of the osteoma and its relationship to the three lines, an appropriate surgical approach should be chosen to optimize the diagnostic and treatment plan.

A New Approach in Management of Orbital Adherence Syndrome.

Orbital walls are one of the most common sites of midface fractures and account for ~40% of traumatic injuries in this region. These fractures are often associated with changes in the anatomy of the orbital cavity and frequently affect the orbital inferior wall, infraorbital groove and canal, and medial orbital wall, which leads to changes in its pattern and volume as well. Generally, the forces required for brake superior and lateral walls are greater than those required for thin medial and inferior walls. Disruption of any of these structures leads to the expansion of orbital volume that brings to the appearance of enophthalmos, diplopia, and impaired ocular mobility. The gold standard in the treatment of orbital wall fractures is surgical reconstruction, that includes fracture site exposure, freeing tissue prolapsed into the fracture site, and re-approximating the orbital wall support, usually with an orbital implant. It usually could be achieved by the usage of such as transconjunctival, subciliary, and coronal approaches and implementation of graft and reconstructive materials, including bones, cartilage, titanium, and resorbable mesh. Today, the gold standard in orbital floor reconstruction is the application of titanium mesh orbital plates. However, their implementation could be associated with a number of postoperative complications, such as mispositioning and orbital adherence syndrome. Orbital adherence syndrome is a poorly described and understood phenomenon and appears to occur after the use of large-pored titanium mesh for orbital reconstruction. It usually appears as limited eye movement that appears 1 to 2 weeks after reconstructive procedure. Prevention is possible through careful patient selection and the placement of a smooth interface medium in the initial surgery. The aim of the current study is to present the outcomes of orbital reconstruction done by both orbital mesh and customized ​​smooth-surfaced titanium orbital implants.

Transoral Robotic-Assisted Neurosurgery for Skull Base and Upper Spine Lesions.

The application of the da Vinci Surgical System in neurosurgery is limited due to technical difficulties requiring precise maneuvers and small instruments. This study details the advantages and disadvantages of robotics in neurosurgery and the reachable range of the transoral approach to lesions of the skull base and upper cervical spine. In a cadaver study, the da Vinci Xi robot, lacking haptic feedback, was utilized for sagittal and coronal approaches on 5 heads, facilitating dura suturing in 3, with a 30°-angled drill for bone removal. Perfect exposure of all the nasopharyngeal sites, clivus, sellar, and choana, including the bilateral eustachian tubes, was achieved without any external incisions using this palatal split approach of transoral robotic surgery. The time required to perform a single stitch, knot, and complete single suture in robotic suturing of deep-seated were significantly less compared to manual suturing via the endonasal approach. This is the first report to show the feasibility of suturing the dural defect in deep-seated lesions transorally and revealed that the limit of reach in the coronal plane via a transoral approach with incision of the soft palate is the foramen ovale. This preclinical investigation also showed that the transoral robotic approach is feasible for lesions extending from the sellar to the C2 in the sagittal plane. Refinement of robotic instruments for specific anatomic sites and future neurosurgical studies are needed to further demonstrate the feasibility and effectiveness of this system in treating benign and malignant skull base lesions.

How I do it: single-staged emergency neurosurgical management of frontal penetrating craniocerebral injury with depressed skull fracture.

Penetrating craniocerebral injury associated with depressed skull fracture is an infrequent yet timely neurosurgical emergency. Such injury frequently occurs in the frontal region during traffic accident or stone throw in the civilian setting. As military neurosurgeons, we present our experience in the surgical debridement and reconstruction of this peculiar type of traumatic brain injury. The patient lies supine, the head in neutral position heal by a Mayfield head clamp. The first step is the debridement of the frontal wound. Then, the depressed skull fracture is operated on using a tailored coronal approach through Merkel dissection plane, in order to keep a free pericranial flap. The bone flap is cut around the depressed skull fracture. Neuronavigation allows to locate the frontal sinus depending on whether it has been breached and thus requires cranialization. Brain and dura mater debridement and plasty are performed. Cranioplasty is performed using either native bone fragments fixed with bone plates or tailored titanium plate if they are too damaged. Performing wounded skin closure first and then a tailored coronal approach with free pericranial flap and a craniotomy encompassing the depressed skull fracture allows to treat frontal penetrating craniocerebral injury in an easy-to-reproduce manner.

The Rationale of Coronal Approach to Malar/Zygoma Reduction.

Malar/zygoma reduction is an effective procedure to change a broader, flatter facial appearance to an oval facial shape. Of the intraoral and coronal approaches, the intraoral is the more commonly used technique than the coronal, due to the perception that complications with the coronal approach are significant, and intraoral results are satisfactory. We compared the postoperative effects of both approaches. From 1994 to 1999, we included the 150 intraoral cases that were followed up for 3 years postoperatively. From 2000 to 2018, we changed our technique to the coronal approach and included the 575 cases that were followed up for 3 years postoperatively. We compared the results of our prior intraoral approach with the more recent coronal approach. All cases of the intraoral approach resulted in smaller-sized faces horizontally; however, 90 patients (60%) still had resulting flat-shaped faces due to acute angle formation in the resultant zygoma. There were 141 cases (94%) of partial malunion and 138 cases (92%) of midface ptosis. Among the 575 coronal approaches, 518 cases (90%) resulted in an oval facial shape without acute angled zygoma. There were 161 cases (28%) of visible incision scars, 466 cases (81%) of temporary alopecia, 12 cases (2%) of hematoma, and 29 cases (5%) of temporary frontal facial nerve injury. The intraoral approach led to flat and acute zygomas. The majority of patients experienced midface soft tissue ptosis. In contrast, the coronal approach led to an oval facial shape. The most notable complications of the coronal approach were visible scars and temporary alopecia.

Frontotemporal Brow lift With Suspension to Frontal Bone

Brow position is a key feature to define a fresh and youthful appearance of the periorbital region. Frontotemporal brow lift implies the elevation of both the medial brow and lateral brow and can be performed through an open (coronal), endoscopic, or combined approach. While endoscopic brow lift has the advantage of minimal incisions compared with the open coronal approach, it requires specific equipment, a longer learning curve, and has been associated with high recurrence rates. Herein, the authors’ technique for frontotemporal brow lift is presented, an approach that includes complete access under direct vision to the lateral brow and glabellar area, through 2 limited frontotemporal incisions and a novel method of 3-vectoring suspension to the frontal bone. It has proved to be predictable with long-lasting results.

Does Training Background Influence Outcomes after Coronal Scalp Incision for Treating Craniomaxillofacial Injuries?: A German Pilot Study

ObjectivesTo examine outcomes of the coronal scalp approach to craniomaxillofacial (CMF) fractures performed by oral-maxillofacial or craniofacial plastic surgery residents (OMFS/CFPS-Rs) vs. trauma surgery residents (TS-Rs), and to determine differences in treatment outcomes between both operator groups.MethodsThis retrospective cohort study enrolled a sample of CMF fracture adult patients treated via the coronal approach in a German level one trauma center during a two-year interval. The predictor variable was training background (OMFS/CFPS-Rs vs. TS-Rs; each n = 5). All trainees must assist in ≥ two surgeries before self-performance. The main outcomes were length of hospital stay (LHS) and coronal flap-related complications (CFRCs). Appropriate statistics were computed at α = 95%.ResultsOf the 97 patients identified during the study period; 71 of whom (19.7% females; mean age, 40.2 ± 15.2 years; 46.5% operated by TS-Rs; 38% combined upper and midfacial fractures) met the inclusion criteria. Operative time, LHS, CFRCs, readmission rates, and post-discharge emergency room visits were not significantly different between the trainee groups. 60% of CFRCs were visible/unfavorable or hypertrophic scar with/without alopecia. The number needed to treat of short LHS was 44 (95% confidence interval [CI], 3.9 to 4.8), the number needed to harm of CFRCs was 14 (95% CI, 3.6 to 7.4), i.e., the likelihood to be helped or harmed was 0.32.ConclusionsCoronal flap raising by OMFS/CFPS-Rs does not appear beneficial over that by TS-Rs in terms of LHS and CFRCs evaluated until postoperative month six. Trainees from any surgical specialties could gain partial independence from skilled surgeons in CMF trauma “sub-steps” and favorable clinical outcomes. Further studies in a larger sample cohort are required to confirm this pilot data.

Preauricular Incision Approach as a Management of Zygomaticomaxillary Complex Fracture Reduction: A Case Report

Introduction: A zygomatico maxillary complex fracture is a facial bone fracture that commonly occurs as a centrally and laterally protruding zygomatic area. The effective surgical approach and exact reduction of the displaced fracture is the most important task in the treatment of a zygomatic fracture, from the aesthetic point of view. Determination of surgical approach and the fixation point of zygomatic arch fracture is one of the most challenging procedure. The purpose of this case report is to find out that the preauricular incison approach is one of the effective methods for reduction of zygomaticomaxillary complex fracture. Case Report: A 53 years old male patient presented with right zygomatico maxillary complex fractures. Diagnosis of right side tetrapod zygomatico maxillary complex fracture deformity was done by clinical examination and confirmed by computed tomography which included 3-D reconstruction view. The authors performed 4-point fixation using the preauricular approach to counter the disadvantages of the coronal approach. The results and usefulness of preauricular approach with 4-point fixation are reported in this study. Conclusion: Preauricular incision is an effective surgical approach for the reduction of zygomatic arch fracture. 4-point fixation using the easier-to-manipulate preauricular approach would be more useful than the conventional method that uses the coronal approach. Satisfactory reduction that showed exact correction was observed. In an outpatient follow-up, no complication such as nonunion or malunion was found, and facial symmetry was also shown. In addition, the preauricular scar was hardly observed. Keywords: zygomaticomaxillary complex fracture, preauricular incision, reduction, fixation

ILIF ASSISTIDA POR ENDOSCOPIA POR VIA TRANSILÍACA: ESTUDO EM CADÁVER

ABSTRACT Objective: Demonstrate the feasibility of endoscopic assisted L5S1 intraforaminal lumbar interbody fusion (iLIF) through a transiliac approach. Methods: Ten transiliac iLIF and ten supra iliac iLIF were performed bilaterally at L5S1 in five randomly selected fresh-frozen human cadavers. The following measurements were recorded: distances from the transiliac track to the iliac crest, posterior superior iliac spine, and superior gluteal neurovascular bundle; pelvic parameters; approach angles; cage’s lateral and AP center point ratio (CPR); percentage of the cage crossing the midline in the AP and lateral views. Endplate integrity was assessed through endoscopic visualization. In addition, the facet joint, sacroiliac joint, iliolumbar ligament, and exiting and traversing nerve roots were checked for integrity through anatomic dissection. Results: In the transiliac technique, the axial and coronal approach angles were significantly decreased by 13.5º (95% CI -15.5; -11.5; p value<0.001) and 13.2º (95% CI -15.3; -11.1; p value<0.001), respectively, the sagittal approach angle was significantly increased by 5.4º (95% CI 1.8,8.9; p-value = 0.008), and the AP CPR was significantly higher (MD 0.16; 95% CI 0.12,0.20; p value<0.001). The percentage of the cage crossing the AP view’s midline was increased by 31.6% (95% CI 19.8,43.4; p value<0.001). The integrity of endplates, facet joints, sacroiliac joints, iliolumbar ligament, and exiting and traversing nerve roots was maintained. Conclusion: L5S1 transiliac iLIF is a feasible surgical technique. It allows a more centrally placed interbody cage in the coronal plane without compromising the anterior position in the lateral plane. The integrity of the major anatomic structures at risk was preserved. Evidence Level III: A case-control study.

Evaluation of Mini-Preauricular Incision in the Surgical Management of Condylar Fracture.

Introduction Mandibular fractures have the highest incidence next to nasal bone fractures of which condylar fractures account for one-third of it. Various approaches for condylar fracture include intraoral and extraoral approaches such as coronal, preauricular, postauricular, endaural, endoscopic, rhytidectomy, transparotid, submandibular, and retromandibular approaches. The purpose of this study was to evaluate the mini-preauricular incisionin open reduction and internal fixation of condylar and subcondylar fractures of the mandible. Materials and methods Twenty patients with condylar fracture underwent open reduction and internal fixationunder general anesthesia using a modified mini-preauricular incisionand subdermal dissection approach. Parameters assessed were pain, mouth opening, occlusal derangement, accessibility of fracture site, duration of surgery, neurosensory deficit (facial nerve), postoperative edema, wound infection, wound dehiscence, and scar. Patients were followed up at an interval of one week, one month, three months, and six months. Results On comparing the parameters preoperatively and postoperatively, occlusal derangement, mouth opening, and pain showed statistical significance with a p-value of 0.01, while nerve weakness and scar assessment showed a high level of statistical significance with a p-value of 0.001. The anatomical reduction of the condyle and internal fixation with miniplates was easy when this approach was used. Patients showedtransient facial nerve paralysis only. No permanent damage was noted.The resultant scar was aesthetically acceptable. Discussion The mini-preauricular approach is an effective and safe technique for open reduction and internal fixation of condylar and subcondylar fractures. This approach provided good access, good cosmetic results, and patient satisfaction. This approach resulted in veryless morbidity to the facial nerve.

Contribution of anatomical criteria to surgical approach for treatment of bilateral coronoid hyperplasia

IntroductionBilateral coronoid hyperplasia is a rare condition characterized by a progressive and painless limitation of mouth opening. The treatment consists of coronoidectomy by intraoral or coronal approach. There is no recommendation in the literature on the choice of the surgical approach according to the importance of the hypertrophy. The objective of our study is to search for predictive anatomical criteria of each approach. Material and methodsThese anatomical criteria were evaluated from 3D CT facial reconstructions of 4 male patients aged 4 to 30 years retrospectively after their surgery. A single intraoral approach was used for cases 1 and 2 (group A), a double approach for cases 3 and 4 (group B). Same measurements were performed on 10 male case controls (group C). We performed a descriptive analysis of our results due to an insufficient number of patients. ResultsThe average width of the coronal processes was much greater in group B, when a double approach was necessary, than in groups A and C. In groups A and B, the average height of the coronoid notch is low compared to group C when there is a need for a coronal approach. The width/TZS ratio is increased in group B compared to group C. DiscussionIn our study, 3 criteria could be informative for the choice of the surgical approach: the width at the superior end of the coronoid process, the width/TZS ratio and the height of the coronoid notch but additional data are needed to confirm our therapeutic options.

Interobserver agreement on the sonographic severity grading of shoulder impingement syndrome

BackgroundShoulder impingement syndrome is the painful entrapment of the soft tissues between the acromion and the humeral head. The severity of shoulder impingement could be graded according to the limitation of shoulder joint moment. The reliability of sonographic findings in the grading of shoulder impingement severity grading is required to be evaluated by the consistency of findings between the observers.PurposeTo assess the interobserver agreement in the sonographic severity grading of shoulder impingement syndrome with the help of a ratio between acromion-to-greater tuberosity distance in the abduction and neutral arm position.Material and methodsPatients were examined by two independent observers in the coronal approach with neutral arm position. Acromion-to-greater tuberosity distance was measured in abduction and neutral shoulder position. The ratios of the distances in the abduction and neutral position were calculated to grade the severity of shoulder impingement syndrome.ResultsA total of 78 shoulders were included in this study. A strong agreement was found for the grading of shoulder impingement severity grading between the two independent observers with Kappa value of 0.94. And correlation between the results of the two observers for the severity grading of shoulder impingement syndrome was significant at 0.01 level.ConclusionSeverity grading of the shoulder impingement syndrome was performed based on the ratio of acromion-to-greater tuberosity distance in abduction and neutral arm position. However, the sonographic findings were consistent and a strong interobserver agreement was seen in this sonographic severity grading.

Supramuscular upper blepharoplasty approach to orbital roof and/or lower anterior table frontal sinus fractures: A meta-narrative review

BackgroundAn approach to orbital roof fractures (ORFs) and/or lower anterior table frontal sinus fractures (LATFSFs) is a challenging task. The conventional coronal approach (CCA) appears to suit multiple/complex fractures of the upper face, while periorbital transcutaneous incisions (PTIs), e.g. gull wing, open sky, butterfly, and Lynch incisions, often impair aesthetic outcomes. The aims of this paper were to provide an overview of the supramuscular upper blepharoplasty approach (SUBA) to ORFs/LATFSFs. MethodsUsing a meta-narrative review study design, the investigators enrolled published data extracted from PubMed/Medline, Embase, Cochrane Library, and Google Scholar concerning SUBA to ORFs/LATFSFs. Only publications with the highest and most recent level of evidence (LoE) in English, French or German available until 6 May 2022 were included. The LoE were evaluated using the 2011 Oxford Centre for Evidence-Based Medicine (OCEBM)’s classification. ResultsIn total, 70 articles were included; however, most contained low LoE. Under general and local anaesthesia, SUBA to ORFs/LATFSFs can be performed safely and appeared to be superior to its submuscular counterpart in terms of fewer risks of adjacent tissue injuries, and speedy operative time (maximal 5 min. in experienced hands). ConclusionsIn contrast to CCA and PTIs, the SUBA is a minimally invasive approach to the ORF/LATFSF with favourable aesthetic outcomes, direct visualisation of the fracture, quick operative time, rare complications, and easy learning.

Fox Eye Effect Using a Transcutaneous Mini-Eyebrow Tail Lift

The eyebrow position is a determining factor related to facial expression, especially concerning the anatomical relationship of the eyebrow with the eyelid. The changing position of the eyebrows with aging influences the individual’s expression and can give negative emotions such as loss of vitality, sadness, and tiredness, and influence facial beauty. Numerous procedures are available to the surgeon to prevent the eyebrows from falling after upper blepharoplasty or lift them in isolation. Despite the various surgical techniques undertaken to manage the eyebrow, conventional approaches are usually more aggressive procedures involving extensive skin resection at the hairline or scalp, endoscopic elevation, and temporal and coronal approaches. Given the growing search for less aggressive procedures that patients better tolerate, this study aims to describe a less invasive variation of the Castañares technique, focused on the elevation of the eyebrow’s tail, which may or may not be associated with blepharoplasty, the Surgical Fox Eye. The technique removes an ellipse of skin above the distal third of the eyebrow close to the hair bulbs and then sutures with a direct elevation of the eyebrow tail. The technique described is ideal for several cases, as it presents predictable and satisfactory clinical outcomes as to the patients’ expectations. It also presents easy healing with extensive durability with minimal chance of complications. Level of evidence: Level V—Opinions of respected authorities, based on clinical experience, descriptive studies, or reports of expert committees.

Computer-Assisted Frontofacial Monobloc Advancement and Facial Bipartition for Pfeiffer Syndrome: Surgical Technique

In patients with Pfeiffer syndrome, several corrections are required to correct facial retrusion, maxillary deficiency, or even hypertelorism. The frontofacial monobloc advancement (FFMA) and the facial bipartition (FB) are the gold standard surgeries. We present the correction of this deformity using a simultaneous computer-assisted FFMA and FB. The 3-dimensional surgical planning defined the virtual correction and bone-cutting guide in view of the FFMA and FB. Coronal and intraoral approaches were combined to perform the osteotomies. Four internal distractors were also placed for the postoperative distraction osteogenesis. We reported 2 cases of computer-assisted surgery with satisfying outcomes. The sagittal deficiency (fronto-facial retrusion) was corrected by FFMA and the transversal abnormality (i.e., hypertelorism and maxillary deficiency) by the FB, then followed by an internal distraction osteogenesis. Computer-assisted surgery is helpful and a reliable option for the management of complex faciocraniosynostosis such as hypertelorism and frontofacial retrusion.

Reconstruction of Cranial Bone Defects Using Polyamide 12 Patient-Specific Implant: Long Term Follow Up.

The main objective of this study was to evaluate the use of patient-specific polyamide 12 implants in cranial bone defect reconstruction.Ten patients who underwent prior decompression craniectomy were selected for the current study. Skull scanning by computerized tomography was performed and used to make virtual planning of the implants to be transformed into physical implant using selective laser sintering. Cranioplasty was performed through coronal surgical approach where cranial implants were fixated using 2.0-mm mini-screws, and plates. Patients follow-up was from 12 to 36 months. Glasgow Outcome Score recorded 1 (good recovery) for all patients. Patient and surgeon satisfaction for the esthetic outcome were measured using visual analog scale as mean of 10 ± 0 and 9 ± 1, respectively. Cranial symmetry index was calculated as mean score of 98% ± 1%, indicating highly accurate symmetry, and preoperative virtual planning and postoperative outcome were compared for accuracy analysis with a mean difference of 0.3197 ± 0.1649, which indicates high accuracy.Polyamide12 cranial implants seem to offer a promising option to cranial bone reconstruction with patient-specific implants. This study ensures proper cosmetic and clinical outcome.
