Precise repositioning of a fractured zygoma is difficult. The traditional approach is through an eyebrow incision, but it can produce a scar that causes aesthetic and psychological problems for the patient. We describe the supratarsal fold approach to expose the frontozygomatic suture and to reduce small displacements of frontal sinus anterior wall; it gives good access and excellent aesthetic results.

Many methods based on biometrics such as fingerprint, face, iris, and retina have been proposed for person identification. However, for deceased individuals, such biometric measurements are not available. In such cases, parts of the human skeleton can be used for identification, such as dental records, thorax, vertebrae, shoulder, and frontal sinus. It has been established in prior investigations that the radiographic pattern of frontal sinus is highly variable and unique for every individual. This has stimulated the proposition of measurements of the frontal sinus pattern, obtained from x-ray films, for skeletal identification. This paper presents a frontal sinus recognition method for human identification based on Image Foresting Transform and shape context. Experimental results (ERR = 5,82%) have shown the effectiveness of the proposed method.

Inappropriate treatments of frontal sinus fractures may lead to serious complications, such as mucopyocele, meningitis, and brain abscess. Assessment of nasofrontal duct injury is crucial, and nasofrontal duct injury requires sinus obliteration, which is often accomplished by autologous grafts such as fat, muscle, or bone. These avascular grafts have an increased risk of resorption and infection, as well as donor site morbidity. For these reasons, pericranial flap, which is vascular, should be used for frontal sinus obliteration. The pericranial flap presented with less morbidity procedure and has decreased infection rates, which justifies its use in frontal sinus obliteration. This paper aims to report a case of a comminuted frontal sinus fracture in a 29-year-old man who was successfully treated by frontal sinus obliteration, using pericranial local flap. The patient was followed up postoperatively for 16 months without infection. Copyright © 2013 by Mutaz B. Habal, MD.

Inappropriate treatments of frontal sinus fractures may lead to serious complications, such as mucopyocele, meningitis, and brain abscess. Assessment of nasofrontal duct injury is crucial, and nasofrontal duct injury requires sinus obliteration, which is often accomplished by autogenous grafts such as fat, muscle, or bone. These avascular grafts have an increased risk of resorption and infection and donor site morbidity. For these reasons, pericranial flap, which is vascular, should be used for frontal sinus obliteration. The pericranial flap presented with less morbidity procedure and has decreased infection rates, which justifies its use in frontal sinus obliteration. This study aimed to report a case of a comminuted frontal sinus fracture with a brief literature review, regarding the use of pericranial flap. The authors report a case of a 23-year-old male subject with a severely comminuted fracture of the anterior and posterior walls of the frontal sinus. The patient was successfully treated by cranialization with frontal sinus duct obliteration, using anterior pericranial flap. The patient was followed up for 16 months with no postoperative complication, such as infection. Pericranial flap is a good resource for frontal sinus duct obliteration because it is a durable and well-vascularized flap...

This study evaluated postoperative results of 8 cases of frontal sinus fractures treated by frontal sinus obliteration with autogenous bone from the anterior iliac crest. Patients and methods: The medical charts of patients sequentially treated for frontal sinus fractures by obliteration with autogenous cancellous iliac crest bone in the Oral and Maxillofacial Surgery Division of this institution were reviewed. From those, eight had complete records and adequately described long-term follow-up. All were operated by the same surgical team. Those patients were recalled and independently evaluated by 2 examiners. Radiographs and/or CT scans were available for this evaluation. Associated fractures and complications were noted. The average postoperative follow-up was 7 years, ranging from 3 to 16 years. The main complication was infection. Four patients (50%) had uneventful long-term follow-ups and four (50%) experienced complications requiring reoperation. Based on the studied sample studied the authors conclude that the obliteration with autogenous bone presented a high percentage of complications in this series.

CONTEXT: Paranasal sinus cancer is considered rare, with an incidence of less than 1 per 100,000 per year, with the frontal sinus being the primary site in only 0.3%. We report a case of adenocarcinoma arising in the frontal sinus. DESIGN: Case report. CASE REPORT: A 59-year-old woman, secretary, came in February 1998 with a 4-month history of low intensity frontal headache. She denied contact with wood dust. On examination a non-tender swelling was noted over her right forehead next to the medial aspect of the right orbit. CT scan showed a soft-tissue mass involving frontal sinus with intracranial invasion through the posterior wall. The anterior ethmoid sinus and the medial aspect of the right orbit were also involved. MRI demonstrated dural thickening in communication with the frontal mass. She underwent an en-bloc tumor resection by craniotomy including orbital clearance. Histology revealed an adenocarcinoma. After surgery she had tumor recurrence, and chemotherapy and radiotherapy were started resulting in partial improvement.

Background: The surgical management of recalcitrant frontal sinus disease has been a dilemma for otolaryngologists for many years. Although the osteoplastic flap with obliteration has been the gold standard of treatment for years, the modified endoscopic Lothrop (MEL) procedure recently has been advocated as an alternative. However, little is known about the effect of this procedure on the mucociliary drainage of the frontal sinuses postoperatively and this animal study addresses this issue. Methods: Fourteen sheep underwent the MEL procedure. The sheep were randomized regarding the use of postoperative irrigation via minitrephines. Each sheep had a nuclear medicine -scintigraphy frontal sinus clearance study via minitrephines performed on each frontal sinus preoperatively and then 3 months postoperatively. Then, the results of these studies were compared. Results: The scans revealed a trend toward faster clearance times postoperatively. However, this decrease was not statistically significant. Importantly, there was no trend or significant increase in clearance times postoperatively. Also, the use of postoperative irrigation was associated with a nonsignificant trend toward faster clearance times postoperatively. Conclusion: The MEL procedure has no adverse effects on the mucociliary clearance of the frontal sinus at 3 months postoperatively. Irrigation of the frontal sinus in the immediate postoperative period showed a trend toward improved postoperative mucociliary function at 3 months.

Frontal sinus and frontal recess surgery remain a challenge for endoscopic sinus surgeons. In order to remove obstructing cells from the frontal recess and frontal sinus, the surgeon needs to have a clear understanding of the anatomy of this region. The technique presented uses high-definition computerized tomography scans to create a 3-dimensional picture of the cellular structure of this region, which allows surgeons to formulate a step-wise surgical plan prior to surgery and encourages cell-by-cell removal of the obstructing cells during surgery. This improved understanding of the anatomy of this complex region should allow the surgeon to perform a competent and complete dissection with improved results.; http://www.elsevier.com/wps/find/journaldescription.cws_home/623163/description#description; Peter-John Wormald

There have been very few studies of frontal sinus development and its association with other growth parameters in humans. The aim of this study was to investigate the relationship of frontal sinus development with somatic and skeletal maturation in a sample of Aboriginal Australians. The sample comprised 31 individuals, of whom 17 were males and 14 females. For the selected subjects the following records were available: lateral head radiographs, hand-wrist radiographs and stature recordings, generally covering the age range from 7 to 18 years. Descriptive statistics for frontal sinus size, skeletal ossification and body height were calculated at yearly intervals and comparisons made between the sexes. Growth velocities in frontal sinus height, frontal sinus depth and stature were also calculated for both sexes. The frontal sinus was found to display a well-defined adolescent growth spurt, with its peak velocity occurring after the peak velocity in body height. Females were found to attain peak velocity in sinus height earlier, on average, than males but they attained peak velocity in sinus depth at a similar age to males. The sequence of hand-wrist ossification events followed a similar pattern in both sexes, with events in females occurring approximately one year earlier than those in males. These results indicate that an adolescent spurt is present in frontal sinus growth and that the spurt tends to occur after statural velocity has peaked. Hand-wrist ossification events also tend to have a close relationship to peak statural and frontal sinus velocity and these relationships may be useful in clinical situations for predictive purposes.; A.

Background: This study was designed to evaluate the extent of restenosis that occurs after an endoscopic frontal sinus drainage Draf type III (Draf III; modified Lothrop procedure) using a modified technique with reconstruction of the frontal sinus drainage pathway with mucosal transplants, in combination with occlusive postoperative care. Methods: Retrospective case series was performed with 24 consecutive patients undergoing Draf III drainage between 2005 and 2010 using the modified technique of covering the bare bone with mucosal transplants from the nasal septum. To ensure optimal moist wound healing, occlusion of the nose was realized by taping the nose for 2 weeks postoperatively. Frontal ostium measurements were done intraoperatively and at follow-up visits for a minimum of 12 months. Data on patient history, demographics, comorbidities, and computed tomography scans were collected. Results: Mean follow-up was 25.6 months. Eight patients were lost to follow-up. Ninety-four percent of frontal sinus neo-ostia remained open. One patient needed revision surgery using an osteoplastic flap with obliteration. The frontal neo-ostium narrowed by an average of 36.9% from 20.5 × 12.5 to 15 × 9.6 mm. On average, three visits were needed for postoperative care. The patients did not experience significant pain throughout the postoperative healing time. Conclusion: The modified Lothrop procedure is a well-established technique in endoscopic sinus surgery to handle difficult frontal sinus drainage pathways or revision surgeries. The modified technique provides good results in combination with minimized postoperative care and morbidity. A comparative study would be necessary to show superiority to the standard method of Draf III.; Tanja Hildenbrand...

OBJECTIVES/HYPOTHESIS: Patients with aggressive nasal polyp recurrence form an important subgroup of patients with refractory sinus disease. The objectives of this study were to establish patterns of polyp recurrence and evaluate the effect of frontal sinus surgery (Draf 2a vs. Draf 3) on polyp recurrence. STUDY DESIGN: Retrospective cohort study reviewing 338 consecutive operations. METHODS: Polyp recurrence was defined according to the Lund-Kennedy mucosal edema score. Survival analysis methods were used for statistics. RESULTS: After complete sphenoethmoidectomies, Draf 2a frontal sinusotomies, and middle meatal antrostomies persistent polyp recurrence occurred in 19.8% of patients after 6 months and increased to 22.7% of patients after 12 months. Polyps first recurred in the area of the frontal sinus/ostium (55%) followed by the ethmoids (38%). Asthma and aspirin sensitivity were the most important variables affecting recurrence (hazard ratios, 1.71, 1.79, respectively; P < .05) The Draf 3 procedure was a significant factor in reducing recurrence, especially in asthma and aspirin intolerant patients. The overall revision rate was 18% (follow-up duration >12 months, median = 29 months), with a 37% revision rate in the FESS group versus 7% in the Draf 3 group (P < .001). Survival analysis showed that the Draf 3 significantly reduced the risk of revision (hazard ratio = 0.258...

The research described in this PhD thesis follows an extensive literature review of the role of the medical and surgical management of CRS. Despite the utilization of surgery to alleviate the symptoms of CRS refractory to medical therapy, there are clear deficiencies in our understanding of what type of surgery to perform, and how extensive this surgery should be so as to maximize long-term symptom alleviation and control. Particular controversy exists regarding addressing the frontal sinus with a wide variety of philosophies employed, but with limited scientific rationale to support such approaches. Chapter two describes a prospective study to validate a quality of life tool, the Adelaide Disease Severity Score. This study showed a simple 5 question tool directly related to sinus symptoms and visual analogue quality of life score correlated very highly with other more complex rhinological quality of life tools – the SNOT 20/22. It further correlated with radiological disease burden (Lund Mackay CT score) and endoscopic disease (Lund Kennedy endoscopic score) burden. This study validated our use of this tool to measure quality of life and symptom improvement in patients undergoing surgery. Chapter three describes a detailed retrospective study of the outcomes of primary frontal sinus surgery. This is the largest study in the literature of primary frontal surgery and forms the basis to support an approach where the diseased frontal sinus should be addressed surgically to optimize long-term outcomes. It also identified that certain anatomical factors such as a narrow frontal ostium seemed to play a role in persistence of symptoms. This raised questions as to whether these outcomes were as successful for revision and extended frontal sinus surgery. Were there identifiable risk factors for success and failure? The fourth chapter describes the outcomes of primary and revision standard frontal sinus surgery and investigates which patient...

Background: Recent articles have published guidelines regarding the role of endoscopic surgery in the removal of frontal sinus osteomas. These guidelines recommend the endoscopic approach for small osteomas but recommend an osteoplastic flap for larger tumors. This study presents a series of endoscopically resected tumors both large and small. Methods: Retrospective chart reviews were performed. Charts were reviewed of all patients who underwent surgical resection of a frontal sinus osteoma from 1998 to 2008. Sinus CT scans were reviewed and each tumor was staged according to Kennedy's grading system proposed in 2005. Results: Twenty-three patients, 8 with a grade IV tumor, 6 with a grade III tumor, and the remaining with a grade I or II tumor, underwent endoscopic resection of a frontal sinus osteoma. In 15 patients a modified Lothrop procedure was performed for tumor removal. In addition, a blepharoplasty incision was used in one patient for removal of a large orbital extension of the tumor and another underwent an enlarged frontal sinus trephine performed via a browline incision. In the remaining patients a frontal sinusotomy with minitrephination provided enough access for tumor removal. Over an average follow-up of 36 months no recurrences were noted. Symptoms improved in all but one patient. There were no postoperative complications. Conclusion: Endoscopic resection of both large and small frontal sinus osteomas is feasible. In this article we have shown successful removal of large osteomas that fill the entire frontal sinus with the modified Lothrop procedure.; Seiberling...

Background: This study reviews the role of frontal sinus minitrephination in today's era of endoscopic sinus surgery. Retrospective chart review was performed of 163 patients undergoing a total of 149 bilateral and 39 unilateral frontal sinus minitrephinations. Methods: Charts were reviewed for patient demographics and outcomes. Details obtained from the chart included type of surgery performed, reason for minitrephination placement, pathology, Lund score, complications and endoscopic patency. Results: One hundred eighty-eight minitrephines were placed during 80 modified Lothrop and 108 frontal sinusotomies. Trephines were placed where there was dificulty finding the frontal recess, severe edema/ polyps, obstructing frontal cells (type3/ type 4 frontoethmoidal cells and intersinus septum cell), and to aid the dissection and postoperative irrigation during the modified Lothrop. Twelve complications occurred with infection at the trephine site being the most common. Follow-up ranged from 2 to 122 months (average, 25.5 months) with 92% showing endoscopic patency at least visit. Conclusion: Frontal sinus trephination is a safe useful procedure that can be extremely helpful in identifying the pathway to the frontal sinus. Fluorscein flushes through the trephine help guide the dissection in a modified Lothrop. Lastly...

Surgery on the frontal recess and frontal sinus remains a challenge for endoscopic sinus surgeons. This paper examines the philosophy behind such surgery and presents a technqiue for 3-dimensional reconstruction of the anatomy of the frontal recess and frontal sinus. Utilizing this anatomical reconstruction the surgeon is encouraged to develop a pre-operative step-by-step surgical plan for each cell identified within the frontal recess and frontal sinus and thereby predict the anatomy of this region before surgery is undertaken. An increased understanding of the anatomy of this region should improve the surgeon's surgical confidence and ability to remove all the obstructing cells from the frontal sinus ostium.; http://www.rhinologyjournal.com/article/view_abstract.php?mgzn_id=120&rtcl_id=556

Aims: The use of multiplanar reconstructed computed tomography (CT) images of frontal recess and sinuses was assessed with regard to depiction and understanding of anatomy and effect on surgical approach. Materials and Methods: Three otorhinolaryngologists and one radiologist read CT scans of 43 patients referred for routine paranasal sinus scans. Spiral (helical) CT scans were obtained and coronal and parasagittal reconstructions were imaged. Three hundred forty-two readings were analyzed. The scans were assessed in the coronal plane and then in the parasagittal plane. The images were assessed for (i) Bent and Kuhn classification of frontal ethmoidal sinus air cells, (ii) size of frontal sinus ostium (assessed as unsure, normal, small, or large), (iii) use of parasagittal scans regarding additional understanding of the anatomy with particular reference as to how the agger nasi cell and frontal ethmoidal cells were arranged in a three-dimensional space, and (iv) if the parasagittal scan and subsequent three-dimensional picture created altered the surgical approach. The first two criteria were assessed in the coronal plane and then in the parasagittal plane. Results: There was no statistically significant difference between the Bent and Kuhn classification of frontoethmoidal cells on coronal and reconstructed parasagittal images (t-test; p > 0.05). The parasagittal scans were significantly better than the coronal scans for identifying and assessing the size of the frontal sinus ostium (p < 0.001; chi-square test). Assuming an intraobserver change rate (repeat error) of 10% on CT scan observations...
