Functional and Esthetic Outcomes of Either Surgically or Conservatively Treated Anterior Frontal Sinus Wall Fractures: A Long-Term Follow-Up

Study Design Retrospective cohort study. Objective Frontal sinus fractures (FSFs) can lead to a range of clinical challenges, including facial deformity, impaired facial sensation, cerebrospinal fluid (CSF) leakage, sinus drainage impairment, chronic sinus pain and mucocele formation. The optimal management approach, whether surgical or conservative, remains a topic of ongoing discussion. The aim of this study was to evaluate and compare the functional and esthetic outcomes of patients with surgically and conservatively treated FSFs. Methods In this retrospective study, patients treated for FSFs at the Karolinska university hospital 2004 to 2020 were identified in hospital records and invited to participate in a long-term follow-up. Sequelae and satisfaction with the esthetic result were assessed trough questionnaires and physical examinations. Results A total of 93 patients were included in the study, with 49 presenting isolated anterior wall fractures and 44 presenting combined anterior and posterior wall fractures. Surgical intervention was performed in 45 cases, while 48 were managed conservatively. Among patients with moderate anterior wall fractures (4-6 mm dislocation), 80% of surgically treated patients compared to 100% of conservatively treated patients expressed satisfaction with their cosmetic outcomes at follow-up ( P = .03). In conservatively treated patients with a forehead impression, the anterior wall fracture dislocation ranged from 5.3 to 6.0 mm ( P < .0001). Approximately 50% of surgically treated patients vs 15% of conservatively treated patients developed impaired forehead sensation at follow-up ( P = .03). Thirty-six percent of surgically treated patients reported dissatisfaction with surgery-related scarring, particularly those who underwent surgery via laceration or bicoronal incision. Conclusions This study suggests that anterior FSFs with a dislocation of 5 mm or less can be effectively managed conservatively with high patient satisfaction, low risk of long-term forehead sensation impairment and without potential development of forehead impression. Bicoronal incision or incision via a laceration may be associated with esthetic dissatisfaction and late sequelae such as alopecia.

Management of frontal sinus fractures requiring surgical intervention: An analysis of a case series.

<b><br>Introduction:</b> Isolated frontal bone fractures constitute 5-15% of traumatic facial fractures cases, with frontal sinus fractures categorized into anterior wall, posterior wall, or complex fractures. The approach is tailored to fracture type and bone fragment displacement. This paper presents the summary of surgical management in patients with isolated and complex fractures of the anterior wall of the frontal sinus.</br> <b><br>Material and Methods:</b> Five patients with different frontal sinus fractures were treated surgically. The same management protocol - diagnosis and surgical intervention was implemented in all cases The retrospective analysis included fracture assessment, surgical approach, and long-term outcomes evaluation.</br> <b><br>Results:</b> The most common cause of fractures was falls, while two complex fractures involved the anterior and posterior walls. External approach, bone fragment removal, endoscopy, and external stabilization were employed in all cases. One patent required delayed revision surgery due to retaining metallic foreign body. Follow-up radiological examinations showed proper healing and cosmetic outcomes were satisfactory in all of the cases.</br> <b><br>Conclusion:</b> Surgical management of isolated fractures of the frontal sinus anterior wall, involving bone fragment removal, realignment, and endoscopy, yielded satisfactory functional and cosmetic outcomes without internal or external stabilization. Long-term monitoring and symptom assessment are crucial, especially in cases with penetrating injuries and foreign body risk.</br&gt.

Prognosis of Performing Split-Rib Bone Graft for Cranial Bone Defects.

Frontal sinus anterior wall defects occur because of various diseases, causing not only aesthetic problems, such as forehead bulging and upper eyelid ptosis, but also exerting physical pressure on the brain or optic nerve. Therefore, this study aimed to evaluate the prognosis of performing split-rib bone graft for frontal sinus anterior wall defects. This study included 30 patients who received a split-rib bone graft for a frontal sinus anterior wall defect. The sizes and volumes of the defects and grafts were measured using three-dimensional computed tomography before, after, and every 6 months for 2 years after the surgery. The Medical Imaging Interaction Toolkit was used for analysis. The average size and volume of the grafts were 27.29 cm 2 and 5.88 cm 3 , whereas they were 23.76 cm 2 and 4.80 cm 3 at 24 months after surgery, respectively. In a graft size and volume of less than 27 cm 2 and 6 cm 3 , respectively, the rate of graft take was greater than 80% during long-term observation. The younger the age, the higher the rate of graft take. No difference was found in the defect causes. Absorption occurred for up to 18 months. Frontal bone defect reconstruction revealed the stable results of the split-rib bone graft over a long period when the size and volume were less than 27 cm 2 and 6 cm 3 , respectively. Furthermore, bone resorption was seen in more than 20% to 30% of the patients, and the rate of resorption increased with age; thus, it is appropriate to consider overcorrection and other reconstruction methods.

Local Approaches for the Reconstruction of Frontal and Naso-Orbito-Ethmoidal (NOE) Fractures: Presentation of a Clinical Case and Literature Review

Naso-orbito-ethmoidal (NOE) fractures are considered a challenge in reconstruction, due to the anatomical structures involved, such as the medial canthal ligament and the lacrimal apparatus [1], which leads to a complex functional and aesthetic compromise. For surgical access to the area, the use of the coronal, Lynch-Howarth, glabellar “open sky”, “gull wings” and a combination of the last two are described. However, the severity of the trauma and mainly the neurological compromise of the patient will dictate the choice of the approach that allows functional and comprehensive repair of the affected region. In cases where there is no neurological compromise and it is not necessary to carry out a subcranial approach, the use of local approaches is justified, providing adequate visibility and direct access to the fractured region, allowing an adequate reduction and placement of fixing material. A clinical case of anterior frontal sinus wall fracture and NOE fracture are presented, performing the combination of the gull-wing and open-sky approach, described as butterfly wings, achieving adequate visibility and reconstruction.

УДАЛЕНИЕ ГИГАНТСКИХ ОСТЕОМ ФРОНТОЭТМОИДАЛЬНОЙ ОБЛАСТИ С ОДНОМОМЕНТНОЙ РЕКОНСТРУКЦИЕЙ ДЕФЕКТА ЛИЦЕВОЙ СТЕНКИ ЛОБНОЙ ПАЗУХИ

Objective: To develop an appropriate method for removing giant frontoethmoidal osteomas and the immediate reconstruction of the anterior wall of the frontal sinus. Methods: Between 2016 and 2020, five patients (4 men and 1 woman) were admitted with an osteoma of the paranasal sinuses, of which three (2 men and 1 woman) were diagnosed with giant osteomas of the frontal and ethmoid region. The patients were aged 28 to 49 years. Routine clinical examinations were carried out, including collecting patient history and a CT scan of the paranasal sinuses. The giant osteomas were removed by minimally invasive transnasal endoscopic surgery with a combined anterior wall approach to the frontal sinus. The tumour size was reduced by excision with a surgical drill before removal to minimise the defect in the frontal sinus's anterior wall. The procedure was completed with the immediate reconstruction of the anterior wall of the frontal sinus using titanium nickelide mesh. Results: The length of hospital stay was 10 days. Wound healing occurred by primary intention, and the sutures were removed on the 8th day. Followup periods were between 1 month and 1 year. Follow-up examinations were carried out 1 week, 1, 6 and 12 months after hospital discharge. On the follow-up CT scans performed a year after the operation, the implanted titanium nickelide mesh was stable, the aeration of the frontal sinus was normal, and satisfactory cosmetic outcomes were reported. Conclusion: CT is the gold standard in determining the size of the osteoma, its spread, and the state of the walls of the paranasal sinuses. A combined surgical approach and debulking of the giant osteomas using a surgical drill with the immediate reconstruction of the anterior wall of the frontal sinus by titanium nickelide mesh produce favourable outcomes. Keywords: Osteoma, benign tumour, frontal sinus, surgical treatment, frontal recess, titanium nickelide mesh.

Three-Dimensional Custom-Made Surgical Guides in Facial Feminization Surgery: Prospective Study on Safety and Accuracy.

Facial feminization surgery (FFS) includes several osseous modifications of the forehead, mandible, and chin, procedures that require precision to provide the patient with a satisfactory result. Mispositioned osteotomies can lead to serious complications and poor aesthetic outcomes. Surgical cutting guides are commonly employed in plastic and maxillofacial surgery to improve safety and accuracy. Yet, to our knowledge, there is no report in the literature on the clinical application of cutting guides in FFS. The authors sought to assess the safety and accuracy of custom surgical cutting guides in FFS procedures. A prospective follow-up of 45 patients regarding FFS with preoperative virtual planning and 3-dimensional custom-made surgical guides for anterior frontal sinus wall setback, mandibular angle reduction, and/or osseous genioplasty was conducted. Accuracy (superimposing preoperative data on postoperative data by global registration with a 1-mm margin of error), safety (intradural intrusion for the forehead procedures and injury of the infra alveolar nerve for chin and mandibular angles), and patient satisfaction were assessed. A total 133 procedures were documented. There was no cerebrospinal fluid leak on the forehead procedures or any infra alveolar nerve or tooth root injury on both chin and mandibular angle operations (safety, 100%). Accuracy was 90.80% on the forehead (n = 25), 85.72% on the mandibular angles (n = 44), and 96.20% on the chin (n = 26). Overall satisfaction was 94.40%. Custom-made surgical cutting guides could be a safe and accurate tool for forehead, mandibular angles, and chin procedures for FFS.

Clinical Inspection and Image Exams Evaluation of Traumatic Wounds: A Case Report

The face is in a position exposed to trauma, which often leads to soft tissue rupture, favoring the penetration and retention of foreign bodies. The present paper is a case report which aims to clarify some pitfalls in the evaluation of traumatic wounds. A 28-year-old female who was a victim of an automobile accident, presenting lacerations in the face already sutured during our evaluation, with suspicion of bone fractures. Computed tomography evaluation showed comminuted fractures in the anterior frontal sinus wall and foreign bodies similar to glass fragments within the frontal sinus and right orbit. Surgical treatment was planned and performed to reduce bone fractures and remove the foreign bodies. The patient is in postoperative follow-up without major complaints. The present study contributes to the current literature with a case where a careful diagnosis, with the collection of the history of the wounds, careful inspection of the wounds under suitable conditions lead to a good treatment of the lacerations and identification of foreign bodies.

Minimally Invasive Technique to Reduce the Isolated Anterior Wall Fracture of the Frontal Sinus.

Conventional open reduction and internal fixation of frontal sinus anterior wall fractures are associated with risks of visible scarring and limited access to the nasofrontal duct. The goal of this study was to report the minimally invasive surgical techniques and their results in cases with frontal sinus anterior wall fractures. A retrospective study was performed on 20 consecutive cases of isolated anterior wall fractures of the frontal sinus between July, 2008 and February, 2017. Causes of injury, interval between the injury and operation, and operation time were reviewed. The fractures were reduced using the minimally invasive techniques of endoscopic endonasal reduction or reduction through a small trephination. Anatomical and aesthetic outcomes were evaluated, and postoperative complications were reviewed. The fractures were reduced with endoscopic endonasal techniques in 11 patients and through a small trephination with a minimal incision in the forehead in 9 patients. The fractures were successfully reduced in all cases. The mean follow-up period was 21.2 months, and no postoperative complications were observed. For isolated anterior wall fractures of the frontal sinus, minimally invasive techniques, such as endonasal endoscopic reduction or reduction through a small trephination, are safe and effective options.

Osseous Transformation with Facial Feminization Surgery: Improved Anatomical Accuracy with Virtual Planning.

Facial feminization surgery entails a series of surgical procedures that help the transwoman pass as their affirmed gender. Although virtual surgical planning, with intraoperative cutting guides, and custom plates have been shown to be helpful for craniomaxillofacial reconstruction, they have not yet been studied for facial feminization surgery. The authors used cadaveric analysis for morphologic typing and to demonstrate the utility of virtual surgical planning in facial feminization surgery procedures. Male cadaveric heads underwent morphologic typing analysis of the frontal brow, lateral brow, mandibular angle, and chin regions (n = 50). Subsequently, the cadavers were split into two groups: (1) virtual surgical planning intraoperative cutting guides and (2) no preoperative planning. Both groups underwent (1) anterior frontal sinus wall setback, (2) lateral supraorbital recontouring, (3) mandibular angle reduction, and (4) osseous genioplasty narrowing. Efficiency (measured as operative time), safety (determined by dural or nerve injury), and accuracy (scored with three-dimensional computed tomographic preoperative plan versus postoperative result) were compared between groups, with significance being p < 0.05. For frontal brow and lateral lower face, morphologic type 3 (severe) predominated; for lateral brow and chin, type 2 (moderate) predominated. For frontal sinus wall setback, virtual surgical planning improved efficiency (19 minutes versus 44 minutes; p < 0.05), safety (100 percent versus 88 percent; p < 0.05; less intracranial entry), and accuracy (97 percent versus 79 percent; p < 0.05) compared with no preoperative planning. For mandibular angle reduction, virtual surgical planning improved safety (100 percent versus 88 percent; p < 0.05; less inferior alveolar nerve injury) and accuracy (95 percent versus 58 percent; p < 0.05). Preoperative planning for facial feminization surgery is helpful to determine morphologic typing. Virtual surgical planning with the use of cutting guides/custom plates improved efficiency, safety, and accuracy when performing four key craniofacial techniques for facial feminization.

Frontal sinus obliteration using autogenous abdominal fat versus autogenous bone: Randomized control clinical trial

Aim: The aim of this study was to compare postoperative complications and donor site morbidity following frontal sinus obliteration with autogenous abdominal fat compared to autogenous bone harvested from anterior iliac crest. Research question: Will frontal sinus obliteration with autogenous abdominal fat result in less sinus and donor site complications compared to sinus obliteration with autogenous bone harvested from anterior iliac crest? Materials and Methods: This was a randomized controlled trial conducted on 10 patients with frontal sinus anterior wall fracture indicating frontal sinus obliteration. In group I, the sinuses were obliterated with autogenous abdominal fat. While in group II, the sinuses were obliterated with autogenous bone harvested from anterior iliac crest. Sinus postoperative assessment was performed clinically and radiologically to evaluate postoperative complications (local sinus pathology including sinusitis, mucocele, pyomucocele, wound infection, wound dehiscence, esthetic deformity). Donor site morbidity was assessed for the presence of any complication, postoperative pain intensity and duration. Results: Both groups showed no postoperative sinus complications. Group II showed donor site higher pain intensity and longer pain duration with statistically significant difference when compared to group I.. Conclusions: Abdominal autogenous fat seemed to be a better frontal sinus obliteration material compared to autogenous bone harvested from iliac crest, thanks to its lower donor site morbidity. However, we recommend further investigations with longer follow up periods to elucidate more about this topic.

Windshield glass fragment mimicking a nasal fracture

A male patient with facial trauma by road traffic accident arrived in the emergency room and he was assisted by the Trauma and Neurosurgery team. After clinical evaluation a frontal sinus anterior wall fracture plus a nasal fracture were diagnosed. On the primary OMS examination was checked multiple facial lacerations and gross nasal dorsum deviation with pain, nasal airway obstruction and crepitus with clinical diagnosis of a nasal fracture. After radiologic exam a piece of windshield glass that was superimposed on the nasal bones simulating a nasal fracture was visualized.

External endoscopic multiportal frontal sinus obliteration for laterally pneumatized frontal sinus: a feasibility study

IntroductionOsteoplastic flap procedure is a standard method used for frontal sinus obliteration. Endoscopic external frontal sinus obliteration is a minimally invasive new technique confined to small-sized and medium-sized pneumatized frontal sinuses.ObjectiveThe aim of this study was assess the feasibility and surgical application of this technique for far-lateral pneumatized frontal sinuses.Materials and methodsTen sides of adult dry skull were assessed for frontal sinus pneumatization and supraorbital cells by computerized tomography. Three sides were selected with frontal sinus pneumatization extending beyond midorbital line. Feasibility of obliteration of frontal sinus was tested. Endoscopic external multiportal frontal sinus approach was done using angled endoscopy and standard instrumentation. Classic frontal sinus trephine port was performed initially to safely locate the frontal sinus. In-situ nondisplaced superiorly based miniosteoplastic flap reaching to midorbital plane was performed providing another port. Additional lateral trephine port beyond midorbital plane was performed. Angled endoscopy and standard instrumentation were used reciprocally through different ports to reach different areas of frontal sinus. Outcome parameters were ability to reach corners of frontal sinus, remove sinus septae and nasofrontal duct, and maintain integrity of anterior wall of frontal sinus. Surgical application was done in two cases of frontal sinus mucocele and meningoencephalocele.ResultsIn three laterally pneumatized frontal sinuses of dry skulls, corners, septae, and nasofrontal ducts could be handled using external multiportal endoscopic approach without disruption of anterior frontal wall. Three ports allowed two-hand surgical technique. Surgical application in two cases with follow-up over 6 months revealed no significant complication. Subcutaneous collection developed in one case after 2 weeks and resolved with medical treatment.ConclusionExternal endoscopic multiportal obliteration is feasible for frontal sinuses with lateral pneumatization beyond midorbital line. This technique is minimally invasive with less morbidity. Long-term follow-up in a larger series is needed.

Osteoma nasofronto-orbitário associado com mucocele e abscesso cerebral

Os autores apresentam o caso de um paciente de 17 anos com esteoma dos seios paranasais, envolvendo a junção do seio frontal e teto da órbita esquerda. Houve expansão do esteoma, inferiormente, para o seio etmoidal, lateralmente, para a órbita e, superiormente, para o seio frontal, com erosão da tábua interna, alcançando a cavidade craniana e resultando em grande abscesso frontal esquerdo. Geralmente, ascomplicações são isoladas, mas, nesse caso, a lenta expansão do osteoma causou alterações orbitárias, nasais e cerebrais. Os aspectos clínicos, radiológicos, cirúrgicos e cosméticos dessa rara tríade (osteoma, mucocele e abscesso cerebral) sãodiscutidos. O diagnóstico prévio e correto dessas lesões é crucial para se evitar um tratamento extremamente agressivo desta doença benigna, pois a maioria das lesões tumorais nesta região é maligna e requer tratamento mais radical. O tratamento desse caso requereu abordagem simultânea do absccesso cerebral e das complicações orbitrárias e nasais do osteoma, com reconstrução do anel orbitrário superior esquerdo e da fossa anterior do crânio. Discutimos a técnica cirúrgica, indicações e vantagens, de acordo com princípios de cirurgia craniofacial e de base do crânio na abordagem desse paciente.

Reduction of Closed Frontal Sinus Fractures through Suprabrow Approach.

BackgroundThe traditional approach for reduction of frontal sinus fractures is coronal incision. Inherent complications of the coronal approach include long scar, hair loss, and long operation time. We describe a simple approach for the reduction of frontal sinus anterior wall fractures using a suprabrow incision that is commonly used for brow lift.MethodsFrom March 2007 to October 2016, the authors identified patients with anterior wall frontal sinus fractures treated by open reduction through a suprabrow incision. Only cases with photographic/radiographic documentation and a minimum follow-up of 6 months were included. The incision line was designed to be at the upper margin of the eyebrow. Medical records and radiographic data were retrospectively reviewed. Surgical outcomes, cosmetic results, and complication were assessed. The patient scale of the patient and observer scar assessment scale was used to assess patient satisfaction for incisional scar at the 6-month follow-up.ResultsThirty-one patients underwent fracture reduction through a suprabrow approach during the study period, with a mean follow-up of 41 months. No patients showed any recurrent displacement, eyebrow asymmetry, or infection during follow-up. Thirteen patients reported their forehead paresthesia postoperatively, and 12 of them had preoperative symptom. One patient complained of incisional scar and underwent scar revision. All patients were satisfied with their eyebrow and forehead contour.ConclusionThe suprabrow approach allowed for an accurate reduction of the fractures in the anterior wall frontal sinus by providing direct visualization of the fracture. This transcutaneous approach can effectively restore forehead contour with acceptable postoperative complications and patient satisfaction.

Place and role of titanium mesh in reconstruction of the frontal bone after trauma

The proper approach and surgical plan in solving impressive comminuted frontal bone trauma is reflected in adequate fixation of numerous fragments, which have to go through proper repositioning and osteosynthesis to achieve adequate stability of the fragments and to return the original contour of the frontal bone and/or frontal sinus walls. We carried out the restoration of the normal bone contour through a quick and easy way of treating frontal fractures using titanium 3D mesh - a technique that involves 'pulling the bone to the network' and fixing it with the mono cortical screws. We present our experience with this technique in solving the case of frontal impressive and comminuted fractures, on the material of 43 patients at the Centre for Medical Emergencies and Neurotrauma Emergency Centre of the Clinical Centre of Serbia through a retrospective cohort study accompanied with technical aspects and clinical results of this simple method application. The study was previously approved by the Ethics Committee of the Clinical Centre of Serbia. In the period of three years 43 patients had fractures in the area of the frontal bone and frontal sinus. The surveyed period was 1st January 2013 to 31st December 2016. The youngest patient was 17 and the oldest 78 years, the average age being 29 years. The main cause was traffic accidents in 29/43 (67.44%) patients, sport in 4/43 (9.30%), falling down from one's own height in 5/43 (11.63%), a fall from a height higher than 2m in 4/43 (9.30%) and machinery operation in 1/43 (2.33%). The ratio towards sex distribution was men/women 3:1. All patients were operated within the period of six days after the injury. The diagnostic evaluation of patients was made with multi slice computed tomography with 3D reconstruction (3D MDCT) pre- and postoperatively, all patients were controlled on the examinations within the follow-up period of the first 12 postoperative months. The stability of the fragments during the surgical procedure was achieved fully, the position of fragments in the reconstructive act was in satisfactory anatomic contours. The aesthetic results were satisfactory and there were no complications related to the procedure applied, such as uncontrolled bleeding from sinus infection, damage to the rear wall of the sinuses and brain. The effectiveness of the applied procedure indicated to us that we had no deformities of the forehead contour and that the full cosmetic result was achieved. The usage of the titanium 3D mesh in solving such complex impressive comminuted fractures showed as the procedure of choice because in a simple manner with good surgical approach it gives excellent results and the procedure is performed with minimal morbidity in addressing primarily comminuted fracture of the anterior wall of frontal sinus and the frontal bone.

Treatment of frontal bone fracture sequelae through inversion of the bone fragment.

Treatment of frontal sinus fractures depends on the structures involved: the anterior wall, the posterior wall and the nasofrontal duct. It may vary from the correction of the defect in the anterior wall to the cranialization with obliteration of the nasofrontal duct. The inversion of the frontal sinus's anterior wall to correct the defect in the fractured region is a good treatment option for sequelae, since this technique eliminates or reduces the use of biomaterial in the area, and allows direct assessment of the permeability of the nasofrontal duct. This work describes the technique of fractured segment inversion for the treatment of frontal sinus fracture sequelae in a motorcycle accident victim.

Reconstructing a Giant Frontal Osteoma With Porex

Osteomas are the most common benign tumors of the paranasal sinuses. They are usually localized in the frontal sinus. Giant osteomas of the frontal sinuses are very rare but readily extend into the intraorbital or intracranial cavity, causing serious complications. This is a report of a 14 year-old boy with a bulging in frontal area and asymptomatic giant osteoma of the frontal sinuses. He had a history of minor trauma that had a bulging after 3 months. However, he referred to a plastic surgeon after 15 months. Computed tomography of the sinuses revealed a 3.5 × 6 cm extremely dense bony mass in the frontal sinus that extended into the left orbit and ethmoid sinus. A bicoronal frontal flap was raised with a V-shaped skin incision starting from the tragus placed 5 cm posterior to the hairline. The osteoma was resected completely in the frontal sinus and the anterior wall of frontal sinus was reconstructed with Porex. The patient has not had any complications until the time of writing this report. Titanium mesh may still be a valuable option, but Medpore Porex has shown to be quite effective in this case.

Small Supracilliary Incision for the Management of Fracture of Supraorbital Rim and Anterior Wall of Frontal Sinus

Abstract With the development of biomedical materials and new techniques in craniofacial sinus surgery, the management of frontal sinus fractures is advanced considerably. We discuss a case of fracture of anterior wall of frontal sinus that was also associated with fracture of the supra-orbital rim and describe supracilliary approach through a small incision (approximately 3 cm) used for the management in this case. With this approach we could successfully expose and reduce the fracture fragments without the need for coronal incision, endoscope or intra-operative imaging.

만성 전두동 전벽 골수염 환자의 수술 후 발생한 전두동 전벽 결손을 Tutoplast®(Allograft Cancellous Bone Chip)를 이용하여 치험한 1예

Osteomyelitis is a severe infection of bone that can arise from a variety of mechanisms. Osteomyelitis is an acute, subacute, or chronic inflammatory process of the bone, secondary to pyogenic bacterial infection, which differs according to patient’s age and infection mechanism. Treatment requires isolation of the pathogens, significant debridement for removal of all infective and necrotic material, and then bony and soft tissue reconstruction. We recently experienced a case of frontal sinus anterior wall defect caused by chronic frontal osteomyelitis in a 62-year-old male patient. The frontal sinus anterior wall defect was repaired using Tutoplast® (allograft cancellous bone chip). (J Clinical Otolaryngol 2014;25:70-74)

The perforation technique: A modification to the frontal sinus osteoplastic flap

Methods: Seven consecutive patients who underwent an osteoplastic flap approach to the frontal sinus by two surgeons using the following surgical variation were analyzed. Rather than using a sagittal saw for cuts through the frontal sinus anterior wall, a 1.1 mm wire-passing drill bit was used to methodically perforate the bone and create a form-fitting beveled cut. The overlying periosteum was preserved. The inferior hinge was created by drilling approximately 4-6 holes across the desired hinge point. An osteotome was used to out-fracture the flap. At the conclusion of the frontal sinus work, the flap was replaced back into its form-fitted window without need for fixation. Patients were evaluated for postoperative ecchymosis, pain, numbness, and cosmetic deformity.
