Orbital subperiosteal hematoma associated with frontal and ethmoidal sinusitis.

BACKGROUND: We report a rare case of orbital subperiosteal hematoma associated with frontal and ethmoidal sinusitis. Common concerns involving the orbital subperiosteal space include abscess, hematoma and tumor. CASE PRESENTATION: A patient presented to our clinic with periorbital swelling and limited extraocular muscle movement in her left eye. Computed tomography revealed a superior subperiosteal mass with frontal and ethmoidal sinusitis. We diagnosed the patient with subperiosteal hematoma and surgical evacuation was performed via superior orbitotomy. Brown serous discharge was drained and biopsy demonstrated fibrin clots. The final diagnosis was orbital subperiosteal hematoma and the patient was discharged with symptoms resolved. CONCLUSION: Orbital subperiosteal hematoma is difficult to distinguish from abscess owing to its rarity and similar presentation. Computed tomography is helpful in diagnosis, and surgical evacuation during the early stages is essential to achieving a good outcome.

Orbital complication of acute ethmoiditis: A Tunisian paediatric cross sectional study.

OBJECTIVE: The anatomical and developmental particularities of sinus cavities in paediatric population lead acute ethmoiditis to be the earliest form of sinusitis in children. Orbital complications are frequent and could lead to visual and neurological impairment. This study investigated the clinical, biological and radiological features of orbital complications. We identified the predictive factors of severe ophthalmological lesions and/or associated cerebral complications of acute ethmoiditis. DESIGN AND METHODS: This cross sectional study included all patients identified as having orbital extension of acute ethmoiditis in the database of a single academic paediatric care centre over a period of 14 years. All orbital and cerebral Scans of the included patients were reviewed and the cohort was classified using Chandler's classification as having less severe lesions (Chandler's 1 and 2) or more serious lesions (Chandler's 3, 4 and 5). RESULTS: In total, 16 patients (12 girls and 4 boys) were included among 39 consecutives cases of ethmoiditis recessed with a complication rate of 41%. Average consultation delay was 4.88 days. The mean age was 4.37 years. Fever was objectified in 13 cases (81%). Six patients (37.5%) had exophthalmos. Orbital extension spectrum was: stage I (n = 4, 25%), stage II (n = 4, 25%), stage III (n = 6, 37.5%), stage IV (n = 1, 6.5%), stage V (n = 1, 6.5%) and intra cranial extension was associated in two cases. Univariate analysis showed that fever, exophthalmos, ophthalmoplegia, positive CRP, age and white blood cells count were not associated with more severe lesions in the CT scan. Initially, all children received intravenous antibiotic treatment. Association of multiple antibiotics was prescribed in 75% of the cases. With 21.07 days ±â€¯5.51 days as a total treatment duration. Only Four patients underwent surgical treatment. CONCLUSION: Orbital complications of ethmoiditis are frequent. No clinical or biological criteria seem to predict the severity of orbital lesions. Both orbital and brain CT scan could help detect eventual complications on time to adapt antibiotic treatment and eventually bring forward surgical intervention.

"L" shape technique for endoscopic sinus surgery: An alternative method.

BACKGROUND: Several techniques for performing ethmoidectomy have been reported. We describe a safe, effective and efficient technique during functional endoscopic sinus surgery (FESS). We present text, images and videos to illustrate our preferred technique during an antero-posterior ethmoidectomy and to provide a multimedia tool for educational purpose. METHODS: A description of the technique without prospective or retrospective data is reported. A complete ethmoidectomy with an L-shape approach is described step-by-step, using the backbiting circular and miniature cutting forceps, with safe exposure of the lamina papyracea (LP) and skull base. RESULTS: In our hands, the L-shape approach for chronic rhinosinusitis with or without polyposis, performed with punch circular cutting and miniature cutting forceps, allowed for a reliably safe and efficient ethmoidectomy. CONCLUSION: The technique described can be added to the armamentarium of the endoscopic sinus surgeon.

Anatomical variation of the pneumatized superior turbinate and its impact on endoscopic sinus surgery in chronic rhinosinusitis.

PURPOSE: The posterior ethmoid sinus is adjacent to important structures, such as the orbit, optic nerve, skull base, and ostium of the sphenoid sinus. The purpose of this study was to examine the effect of pneumatization of the superior turbinate (ST) and its basal lamella, and of the position of the anterior wall of the sphenoid sinus, on opening of the posterior ethmoid and sphenoid sinuses. METHODS: On axial, coronal, and sagittal computed tomography images, 394 sinuses of 197 patients who underwent endoscopic sinus surgery at Toho University Omori Medical Center in Tokyo, Japan, were classified according to the presence or absence of pneumatization of the ST and its basal lamella. The basal lamella of the ST was classified separately into the vertical and horizontal portions. We examined whether the classification of the anterior wall of the sphenoid sinus was associated with the structure of the ST. RESULTS: Pneumatization was observed in the ST in 28 sinuses (7.1%), in the vertical portion of the basal lamella in 127 (32.2%), and in the horizontal portion of the basal lamella in 90 (22.8%). Pneumatization in the horizontal portion of the basal lamella was significantly more common in the anterior sphenoidal wall classified as optic-canal type. CONCLUSION: Consideration should be given to the pneumatization of the ST and its basal lamella and optic-canal-type anterior sphenoidal wall, because these reduce the volume of the posterior-most ethmoid cell and may increase the risk of damaging the skull base and optic nerve.

Advanced surgical technique for invasive fungal sinusitis: endoscopic orbit-sinus combined approach.

BACKGROUND: Invasive fungal sinusitis is usually associated with poor prognosis, but no clear guidelines have been established for surgical treatment. Here, we report the development and application of the endoscopic orbit-sinus combined approach (EOSCA), a novel surgical technique to approach the nasal cavity and orbit concurrently, in patients with invasive fungal sinusitis with orbital infiltration. MATERIAL AND METHODS: Two patients with invasive fungal sinusitis infiltrating the orbit underwent EOSCA. Transnasal endoscopy was performed for maximum debulking of tissues infiltrated by fungi in the nasal cavity and orbit, before making an incision into the palpebral conjunctiva. An endoscope was then inserted into the orbit through the incision in the palpebral conjunctiva to remove adipose tissue and muscles that had been infiltrated by fungi from the orbital regions where the transnasal approach was difficult or impossible. Another surgeon assisted the procedure by operating an endoscope concurrently via the nasal cavity (four-hands technique). RESULTS: We were able to remove lesions safely and with precision, preserving visual acuity and a functional eyeball in both cases. Currently, the patients are alive, with no postoperative complications, recurrence, or disfigurement. CONCLUSIONS: This novel method shows promise as a safe and reliable surgical procedure for patients with invasive fungal sinusitis infiltrating into the orbit, with no postoperative complications, recurrence, or disfigurement.

Silver sucrose octasulfate nasal applications and wound healing after endoscopic sinus surgery: a prospective, randomized, double-blind, placebo-controlled study.

OBJECTIVES: The aim of the present prospective, randomized, double-blind, and placebo-controlled investigation (approved by the Ethical Committee of Padova University Hospital [Italy]) was to assess the effect of a nasal gel containing a combination of silver sucrose octasulfate and potassium sucrose octasulfate (Silsos gel® [SG]) in wound healing after endoscopic sinus surgery (ESS) for chronic rhinosinusitis in terms of: nasal symptoms (SNOT22), endoscopic appearance of the sinonasal mucosa (Lund-Kennedy score), nasal air flow (anterior active rhinomanometry), evidence of mucosal inflammatory processes (nasal cytology and histology), and microbiological growth. METHODS: Thirty-four patients with chronic rhinosinusitis were randomized on a 1:1 ratio to receive after ESS either SG or placebo (contained only the excipients [carbopol and propylene glycol] in the same concentrations as in SG). RESULTS/CONCLUSIONS: Judging from the present prospective investigation on patients who underwent ESS for chronic rhinosinusitis, treatment with SG seems to enable a significantly faster improvement in specific symptoms (assessed on the validated SNOT22 scale) than placebo. Patients treated with SG also had a quicker improvement in the endoscopic appearance of their nasal mucosa after ESS than patients treated with placebo. These endoscopic improvements in the SG group were also confirmed at the long-term follow-up, while the same did not apply to the placebo-treated group.

Image-guided, navigation-assisted Relieva Stratus MicroFlow Spacer insertion into the ethmoid sinus.

Anatomical complexity presents the main challenge in the administration of topical corticosteroid therapy to the paranasal sinus mucosa. This often leads to suboptimal drug delivery due to low concentrations of the therapeutic agent to the intended target area. The Relieva Stratus™ MicroFlow Spacer (Relieva Stratus) is a drug-eluting stent that is temporarily implanted into the ethmoid sinus. The reservoir of the stent is filled with triamcinolone acetonide, which is then slowly released from the device into the ethmoid sinus mucosa. The Relieva Stratus provides local and targeted delivery of the anti-inflammatory agent to the diseased mucosa. This minimally invasive implant is an option when treating ethmoid sinusitis. From January 2011 to November 2013, a total of 52 Relieva Stratus implantations into the ethmoidal cells were performed at the Department of Ear and Oral Diseases at Tampere University Hospital, Finland. C-arm fluoroscopy guidance was employed for 26 sinuses (13 patients) and optical image-guided surgery (IGS)-assisted insertions were performed on another 26 sinuses (13 patients). The accuracy of fluoroscopic insertion is not optimal, but this method is accurate enough to prevent the violation of the skull base and lamina papyracea. IGS enables the precise treatment of the diseased cells. From a technical perspective, IGS-guided insertion is a faster, safer and more exact procedure that guarantees the optimal positioning and efficacy of the implant. Moreover, IGS guidance does not entail the use of ionizing radiation.

Orbital necrotizing fasciitis and osteomyelitis caused by arcanobacterium haemolyticum: a case report.

The facial region is infrequently affected by necrotizing infections. Orbital necrotizing infections are even rarer, seen following trauma, local skin infection, and sinusitis. The authors report a unique case of orbital necrotizing fasciitis and osteomyelitis resulting from Arcanobacterium Haemolyticum ethmoid sinusitis. No prior occurrences of Arcanobacterial species orbital necrotizing fasciitis/osteomyelitis have been reported.A 16-year-old boy presented to the ER with a 3-day history of fever, chills, headache, and sinus pressure. CT scan revealed soft tissue swelling of the right orbit, forehead, and ethmoid sinusitis. Within 24 hours of admission, he suffered rapidly progressive swelling and erythema of the right orbit and forehead with diminished visual acuity, despite broad-spectrum antibiotics. Orbital exploration revealed frankly necrotic fascia and periosteum along the superior aspect. Lateral canthotomy, cantholysis, decompression of the optic nerve, and soft tissue debridement with bone biopsy was performed. Operative specimens isolated Arcanobacterium Haemolyticum. Pathologic examination revealed right orbital osteomyelitis.

Orbital Cellulitis and Subperiosteal Abscess: A 5-year Outcomes Analysis.

PURPOSE: Orbital cellulitis and subperiosteal abscess (SPA) are historically associated with poor outcomes. We seek to characterize current associations with abscess formation, surgical failure and vision loss. METHODS: All cases of orbital cellulitis presenting to an affiliated hospital between April 2008 and 2013 were critically reviewed. RESULTS: Thirty patients met inclusion criteria. Average age was 28.7 ± 24.4. The male to female ratio was 2:1. Abscesses were identified in 56.7% of patients. Adults were less likely than children to present with abscesses (28.6% vs. 81.3%, p = 0.008). Of the other factors analyzed, only antibiotic use before admission (70.5% vs. 23.1%, p = 0.03) and maximum restriction (-2.5 ± 1.2 vs. -0.9 ± 0.7, p = 0.008) were associated with SPA. Temperature at presentation (37.9 ± 0.9 vs. 37.1 ± 0.4, p = 0.04), relative proptosis (5.8 ± 3.3 mm vs. 2.1 ± 1.1, p = 0.002) and abscess volume (4.3 ± 1.3 mm(3) vs. 0.7 ± 0.5 mm(3), p = 0.0004) were associated with progression to surgery. Reoperation was required in 26.7% of patients. Of these, two-thirds had combined superior/medial abscesses that re-accumulated after isolated endonasal surgery. Two of the 3 patients with profound vision loss had a dental etiology. CONCLUSIONS: Only young age, prior antibiotics and degree of restriction predicted the presence of an abscess. Re-accumulation was more common than anticipated, and drainage of superior/medial abscesses by endoscopic surgery alone had the strongest association with surgical failure. Patients with odontogenic abscesses must be treated with particular caution.

Additive Manufacturing of Medical Models--Applications in Rhinology.

In the paper we are introducing guidelines and suggestions for use of 3D image processing SW in head pathology diagnostic and procedures for obtaining physical medical model by additive manufacturing/rapid prototyping techniques, bearing in mind the improvement of surgery performance, its maximum security and faster postoperative recovery of patients. This approach has been verified in two case reports. In the treatment we used intelligent classifier-schemes for abnormal patterns using computer-based system for 3D-virtual and endoscopic assistance in rhinology, with appropriate visualization of anatomy and pathology within the nose, paranasal sinuses, and scull base area.

The effect of two sphenoidotomy approaches on the sense of smell: trans-ethmoidal versus trans-sphenoethmoidal.

BACKGROUND: There are generally two methods to access the sphenoid sinus: either through the natural ostium {trans-sphenoethmoidalor via sphenoethmoidal recess), or by creating a second opening through the posterior ethmoids (trans-ethmoidal).This study psychophysically and subjectively evaluates the effect of the trans-sphenoethmoidal technique to the trans-ethmoidal technique for sphenoid sinusotomy on olfactory function. METHODS: Prospective cohort analysis of 48 patients with comparable sinus disease underwent primary sphenoidotomy via transsphenoethmoidal(n = 24) versus trans-ethmiodal (n = 24) technique between September 2011 and February 2012. The patients had their olfaction measured psychophysically with "Sniffin' Sticks" and subjectively with a visual analogue scale (VAS) pre-operatively and at 5 weeks post-operatively. RESULTS: Psychophysical scores from the Sniffin' sticks provide a Threshold, Discrimination and Identification (TDI) score out of 48.The TDI change (post-operative TDI score minus pre-operative score) as well as VAS change (post-operative VAS minus pre-operativeVAS) were analyzed using t-test analysis, which showed no significant difference between the two measurements. CONCLUSION: If the trans-sphenoethmoidal technique is done meticulously, patients have the same olfactory relief, psychophysically and subjectively, as those undergoing the trans-ethmoidal technique.

Massive thrombosis of bilateral superior and inferior ophthalmic veins secondary to ethmoidal rhinosunisitis: imaging findings.

Ophthalmic vein thrombosis (OVT) is a rare condition occurring secondary to varied etiologies that commonly presents with proptosis, globe dystopia, ophthalmoplegia, periorbital edema, and occasionally diminished visual acuity. It may be related to inflammation of the orbit or paranasal sinuses. We herein report imaging findings of thrombosed superior and inferior ophthalmic veins in bilateral involvement in a 20-year-old male patient without cavernous sinus thrombosis. He presented with pain, swelling, and blurred vision in both eyes. Magnetic resonance (MR) imaging, cerebral MR angiography, and susceptibility weighted imaging were performed. Bilateral superior and inferior OVT due to a complication of ethmoidal sinusitis was diagnosed in the patient. Anticoagulant and systemic broad-spectrum antibiotic therapy was started. His symptoms were recorded at the end of 14 days of the treatment.

Frequency of the odontogenic maxillary sinusitis extended to the anterior ethmoid sinus and response to surgical treatment.

OBJECTIVES: Odontogenic sinusitis usually affects the maxillary sinus but may extend to the anterior ethmoid sinuses. The purpose of this study is to determine the percentage of odontogenic maxillary sinusitis extended to the anterior ethmoid sinuses and determine also the surgical resolution differences between odontogenic maxillary sinusitis and odontogenic maxillary associated to anterior ethmoidal sinusitis. STUDY DESIGN: This is a retrospective cohort study performed on 55 patients diagnosed of odontogenic sinusitis and treated surgically by functional endoscopic sinus surgery. RESULTS: This study showed that 52.7% of odontogenic maxillary sinusitis spreads to anterior ethmoid, causing added anterior ethmoid sinusitis. We found that 92.3% of the odontogenic maxillary sinusitis (who underwent middle meatal antrostomy) and 96.5% of the odontogenic maxillary sinusitis extended to the anterior ethmoid (treated with middle meatal antrostomy and anterior ethmoidectomy) were cured. CONCLUSION: Ethmoid involvement is frequent in maxillary odontogenic sinusitis. The ethmoid involvement does not worsen the results of "functional endoscopic sinus surgery" applied to the odontogenic sinusitis.

Neonatal orbital abscess.

Orbital abscess is life-threatening and rare in children. Reported herein is a term male neonate who had methicillin-resistant Staphylococcus aureus orbital abscess, and a literature review of this disease. A total of 16 neonates diagnosed with neonatal orbital abscess are reported in the literature. There is a mild male predilection and two neonates were delivered prematurely. Leukocytosis, fever, ethmoiditis and associated upper respiratory tract infection were found in approximately half of them. Eight neonates had sepsis and 14 patients underwent surgical intervention. One patient died. Staphylococcus aureus was identified in 14 out of 17 patients. Neonatal orbital abscess is rarely encountered but may be fatal. Although streptococci are prevalent in childhood orbital infection, S. aureus was predominant in neonatal orbital abscess in the present series. Appropriate antimicrobial therapy against S. aureus is essential in treating neonatal orbital abs ess. This case suggests that a higher initial dose of vancomycin may be an effective and safe strategy for severe S. aureus infection in neonates.

An unusual case of an orbital abscess secondary to contralateral sinusitis.

Orbital complications secondary to acute rhinosinusitis can result in permanent blindness or death if not treated promptly and appropriately. Many authors have reported that almost all such patients had abscesses adjacent to the infected sinuses. However, the authors experienced an orbital abscess secondary to contralateral sinusitis. Here, the authors report an 8-year-old patient who had a left superior orbital abscess secondary to a right ethmoidomaxillary sinusitis.

A case report of orbital haemorrhage associated with endoscopic sinus surgery and reversible sight loss: a multidisciplinary approach to management.

We report a case of intraoperative orbital haemorrhage as a complication of endoscopic sinus surgery performed under general anaesthesia. Initial unilateral complete visual loss occurred, but recovered due to accurate and early diagnosis combined with urgent surgical intervention. This patient's case is reported to illustrate the importance of early recognition of clinical signs and how a stepwise approach to management can result in a favourable visual outcome. Moreover, the mechanisms and pathophysiology of visual loss due to orbital haemorrhage following endoscopic sinus surgery are discussed.

[Ability of smell after medialization of the middle nasal turbinate in endoscopic sinus surgery]. / Riechvermögen nach Medialisierung der mittleren Nasenmuschel bei der endonasalen Siebbeinoperation.

BACKGROUND: Endoscopic sinus surgery usually requires a move of the middle nasal turbinate into the midline to achieve a better sight into the ethmoidal sinuses. In this procedure damages of the turbinate are possible, which later can lead to a scarred fixation of the turbinate. Fixing of the turbinate to the septum can avoid this effect, but could reduce smell ability by blocking of the upper nasal duct. MATERIAL: In a prospective study with 83 patients with chronic sinusitis (55% CRS with polyps, 45% CRS without polyps) at the end of the operation the middle nasal turbinates were fixed at the nasal septum with a 4 × 0 stitch. Before the operation and 6 weeks, 3 and 5 months after operation the smell was tested using the "sniffin'sticks" threshold test. RESULTS: After operation the ethmoidal area remained open without developing of relevant synechiae or scars. The smell ability decreased after surgery due to the obstruction of the upper nasal duct, but improved again later. After 5 months the average threshold of smell was better than before operation. Testing of the threshold values with the t-test showed a significant difference (p<0.001) between the pre- and postoperative status. CONCLUSION: The method of medialization and temporary septal fixation of the middle nasal turbinate allows a sufficient ventilation and drainage of the paranasal sinuses after sinus surgery. Due to only temporary fixation of the turbinate at the septum, a permanent obstruction of the upper nasal duct and the olfactory area is prevented. Thus the threshold of smell is not reduced.

Oral levofloxacin-induced optic neuritis progressing in loss of vision.

This case report highlights a rare adverse drug reaction caused by levofloxacin, resulting in optic neuritis progressing into unilateral loss of vision. A 49-year-old male patient was diagnosed to suffer from left maxillary and ethmoid sinusitis and was only prescribed oral levofloxacin 500 mg tablets once daily for 5 days. Within a few minutes after taking the first dose of the drug, the patient experienced respiratory distress, dizziness, confusion with pain, and loss of color vision, followed by almost complete loss of vision in the right eye. The left eye was normal. After ophthalmologic examinations and investigations, he was diagnosed to suffer from optic neuritis, probably (according to Naranjo adverse drug reaction probability scale) induced by levofloxacin.
