[Sepsis in the sphenoiditis patient]

INTRODUCTION

We present a case of sepsis caused by isolated sphenoiditis.

MATERIAL AND METHOD

The case being described concerns 61-year-old woman treated at the Department of Occupational Diseases of Wroclaw Medical University due to body temperature maintaining for 2 months at above 38 degrees C, leucocytosis reaching 14-16 thousand and weight loss of about 4 kg. Detailed diagnostics did not confirm the preliminary diagnosis of system or neoplastic disease. Bacteriological blood examination revealed the presence of staphylococcus aureus susceptible to Vancomycin and Tienam. The attempt of pharmacological treatment did not produced the expected effect. NMR examination of the facial skeleton proved partial shadowing of the Sphenoidal sinus. The patient was admitted for surgical treatment. After the sphenoidal sinus was cut open, mucopurulent contents was found inside. During microbiological examination, staphylococcus aureus with identical susceptibility was cultured from the mucopurulent contents. After 3-week guided antibiotic therapy, permanent temperature regression and permanent improvement of the patient's condition were achieved.

RESULTS

Surgical treatment combined with intensive antibiotic therapy caused the complete regression of symptoms.

CONCLUSION

Isolated sphenoiditis occurs rarely but it still is a serious diagnostic and therapeutic problem. Diagnosis delay and disease progress may lead to life-threatening complications.

Sphenoid sinus fungal balls

OBJECTIVES

We sought to examine the nature of fungal balls of the sphenoid sinus, in particular the exposure of adjacent skull base structures and the potential for surgical morbidity.

METHODS

We retrospectively reviewed our series of 17 cases of sphenoid sinus fungal balls seen between 1998 and 2005 with reference to their diagnosis, radiologic changes, histopathology, and surgical management.

RESULTS

Exposed structures included the pituitary fossa, cavernous sinus, and cavernous internal carotid artery, but this exposure did not result in an increase in perioperative complications. Sclerotic thickening of the sinus walls persisted, probably representing a chronic osteitis in response to concurrent bacterial infection. This appeared to be protective against further sinus wall erosions. Wall erosions did not heal. One patient demonstrated what appeared to be invasive fungal disease from a fungal ball.

CONCLUSIONS

Sphenoid sinus fungal balls can occur with minimal symptoms in a mainly elderly population and require surgical removal. Sphenoid sinus fungal balls have a low rate of operative morbidity and should be effectively managed by transnasal endoscopic sphenoidotomy alone.

Chronic sphenoid sinusitis revisited: comparison of multidetector axial sections, multiplanar reconstructions, and virtual sinoscopy with endoscopic sinus surgery

OBJECTIVES

To assess the role of multidetector computed tomography (CT) and CT virtual sinoscopy in the evaluation of chronic sphenoid sinusitis and to compare the imaging findings with functional endoscopic sinus surgery.

DESIGN

Prospective study.

SETTING

Tertiary care teaching hospital.

PATIENTS

Thirty patients with chronic sphenoid sinusitis referred for preoperative CT.

INTERVENTIONS

Thin-section helical axial CT was performed using a multidetector CT scanner with multiplanar reformation (MPR) and volume-rendered or virtual sinoscopy images. Sixty sinuses were divided into quadrants for analysis. Extrasinus extension was labeled as the "fifth quadrant."

MAIN OUTCOME MEASURES

Imaging findings were compared with those of functional endoscopic sinus surgery, and accuracy of the imaging modality was determined.

RESULTS

Multidetector CT (axial CT and MPR) was found to be 100% sensitive, specific, and accurate in the evaluation of extent of sinusitis, status of the sinus septum, integrity of the optic nerve canal in relation to the sinus, and type of sinus pneumatization. Axial CT and MPR images showed sensitivity of 98% and specificity of 92% compared with functional endoscopic sinus surgery in evaluating the ostia. Regarding carotid canal integrity, axial CT and MPRs were 100% sensitive and 98% specific. Virtual sinoscopy showed sensitivity and specificity of 67% and 92%, respectively, for the 22 ostia that could be visualized and evaluated using this modality.

CONCLUSIONS

Axial multidetector CT with secondary MPRs provide the necessary preoperative information regarding extent of disease and sphenoid sinus anatomy. Virtual sinoscopy is a navigational aid, an adjunct to endoscopy, and an educational tool for surgeons-in-training.

Acute visual loss in a head and neck cancer patient with ocular metastasis and sphenoid pyocele

We report an extremely rare case of head and neck cancer patient with right acute visual loss by ocular metastasis after excluding compressive optic neuropathy by endoscopic decompression of the sphenoid pyocele. The ocular metastasis from head and neck cancer had been reported only once in English literatures. Besides, the patient combined with sphenoid pyocele increases the difficulty in differentiating the etiologies. In this article, we describe the history of this patient and discuss the possible cause of acute visual loss and the treatment strategy. Although to differentiate the etiology of acute visual loss between metastatic malignancy and compressive optic neuropathy remain difficult, treatment strategy should focus on rescuing visual acuity. Ocular metastases should always keep in mind when acute visual loss is encountered in patients with previously treated head and neck squamous cell carcinoma.

Orbital cellulitis and irreversible visual loss owing to acute sinusitis

We report a case with orbital cellulitis and irreversible visual loss caused by asymptomatic acute sinusitis in a patient without symptoms or history of sinusitis. The prompt use of intravenous antibiotics in combination with early surgical drainage may prevent irreversible visual loss in the affected eye, and threatened visual loss in the fellow eye can be reduced.

[Does CT-navigation improve the outcome of functional endonasal sinus surgery?]

INTRODUCTION

Computer-assisted surgery (CAS) has found widespread use in functional endonasal sinus surgery (FESS) over the past few years. The present study investigates if CAS leads to a better outcome in FESS.

MATERIAL AND METHODS

All patients who underwent endonasal sphenoethmoidectomy were enrolled in a prospective, non-randomized study. The procedures were done without CAS (group A) in 2003 and in 2004 with CAS (group B), using a Stryker navigation unit. 62 patients (113 sphenoidectomies) were included in group A and 61 patients (109 sphenoidectomies) in group B. The underlying disease was recurrent chronic sinusitis or polyposis nasi in all patients except for inverted papilloma in one patient of group A and in two patients of group B. The follow-up period was 6 months. Preoperatively and at 6 months postoperatively, a CT-scan was obtained and symptom scores were assessed using a questionnaire.

RESULTS

No significant difference was found between group A and B with respect to symptom scores, and CT-scans preoperatively and at 6 months postoperatively. The operation strategy did not change by the introduction of CAS. The frontal sinus was entered in group A and B in 59% and 64%, respectively. All parameters significantly improved postoperatively, compared to the preoperative values. As far as complications are concerned, two anterior orbital injuries and one retrobulbar haematoma occurred in group A and one postoperative lacrimal stenosis in group B.

CONCLUSIONS

CAS does not lead to a better clinical outcome in FESS. Our data suggest that the rate of complications may be reduced using CAS. However, studies with a much larger number of patients would be necessary for a definite answer to this issue.

Endoscopic transnasal sphenoidotomy with or without ethmoidectomy

OBJECTIVES

We evaluated endoscopic transnasal sphenoidotomy (ETNS) with or without ethmoidectomy in patients with inflammatory sphenoid sinus disease (ISSD).

PATIENTS AND METHODS

A retrospective review was conducted in 42 patients (17 males, 25 females; mean age 41 years; range 17 to 67 years) who underwent ETNS with (n=37) or without (n=5) ethmoidectomy for ISSD. The disase was staged according to our staging system based on computed tomography findings.

RESULTS

Postnasal drainage was the most common symptom (n=37, 88.1%). Chronic rhinosinusitis was accompanied by sinonasal polyps in 25 patients (59.5%). Five patients (11.9%) had isolated sphenoid disease and 16 patients (38.1%) had unilateral disease. Five patients (11.9%) had stage 1, 15 patients (35.7%) had stage 2, and 22 patients (52.4%) had stage 3 disease. Surgery involved 68 sides. Ethmoidectomy was used in 63 sides of 37 patients, eight of whom required a supplementary procedure. At least one complication was seen in eight patients (19%), including severe perioperative hemorrhage (n=2), early postoperative hemorrhage (n=2), minor injuries to the lamina papyracea (n=4), and synechiae (n=5).

CONCLUSION

In patients with isolated ISSD, the direct approach to the sphenoid sinus by ETNS without ethmoidectomy is a favorable technique, whereas ETNS with ethmoidectomy is necessary for patients with concurrent disease in other paranasal sinuses.

Endoskopowe leczenie chorych z wewnątrzczaszkowymi powikłaniami zapalenia zatok

INTRODUCTION

Intracranial complications of sinusitis (cerebral, epidural, and subdural abscesses, meningitis, and dural sinus thrombophlebitis) remain a challenging and current topic. Although they are nowadays relatively rare, prompt recognition of these disease states is important to prevent permanent neurological deficit or fatality. Infection may spread hematogenously or by direct extension. Patients with complications require surgery to remove the focus of infection from the sinuses and drain the abscess. Recently, endoscopic frontal and sphenoid sinus surgery has emerged as the preferred technique for the treatment of the most advanced and complicated chronic sinusitis.

MATERIAL AND METHODS

Records of 7 patients aged from 13 to 65 (mean 30.6) years treated in our department for intracranial complications between January 2002 and September 2006 were analysed retrospectively. The diagnosis of meningitis was established in 2 patients, in one case with accompanying bilateral oculomotor nerve palsy. Cavernous sinus thrombosis, frontal abscess with hemiplegia, cerebral oedema, bilateral oculomotor nerve palsy and retrobulbar optic nerve neuritis with blindness was diagnosed each in one individual. 5 endoscopic bilateral frontosphenoethmoidectomies and 2 endoscopic sphenoethmoidectomies were performed. In one case a frontosphenoethmoidectomy was combined with craniotomy.

RESULTS

All preoperative symptoms subsided in 4 operated individuals. Vision improved in the patient with bilateral retrobulbar optic nerve neuritis. In patients with hemiplegia and bilateral oculomotor nerve palsy the symptoms persisted. No complications of the surgery were observed.

CONCLUSIONS

Surgical treatment of the focus of infection in the sinuses can be accomplished endoscopically via an intranasal approach with less morbidity, easy identification of anatomical structures, physiological drainage of the sinuses and superior cosmetic effects.

[Diagnosis and endoscopic treatment of sphenoid mycetoma]

OBJECTIVE

To investigate the presenting symptoms and signs, endoscopic findings, imaging changes and the clinical outcomes of endoscopic surgery in 23 patients with sphenoid mycetoma.

METHODS

The clinical data and the follow-up results of endoscopic surgery in 23 patients with sphenoid mycetoma, between April 2001 and January 2006, were retrospectively analysed.

RESULTS

The study population included 15 women and 8 men with a median age of 52.7 years. Presenting symptoms included headache (13 cases, 57%) and bloody discharge (9 cases, 48%). The computed tomography scans showed high density shadow in all 23 cases, with 17 cases (74%) had plaque or cord shaped calcification. All patients were treated by endoscopic transnasal approach. No surgical complications were found. Follow-up ranged 3-18 months, all symptoms disappeared, except strabismus in one case after 7 months of operation. The mucosa in surgical cavity is good.

CONCLUSIONS

The most common clinical symptoms of sphenoid mycetoma are headache and bloody discharge. Computed tomography scan has great value for the diagnosis of sphenoid mycetoma. The minimal invasion and the good outcome are the main advantages of the endoscopic surgery.

Invasive sphenoidal aspergillosis: successful treatment with sphenoidotomy and voriconazole

Treatment of invasive sphenoidal aspergillosis is surgical, followed by antifungal therapy, mostly amphotericin B. To optimize the adjuvant antifungal treatment, which is often limited by severe side effects, the new triazole antifungal agent voriconazole with broad coverage of fungal pathogens including Aspergillus was investigated in a study of 4 patients with clinical, radiological and histological signs of invasive sphenoidal aspergillosis. They first underwent endoscopic sphenoidotomy with drainage and extraction of the fungal mass. Postoperatively, 2 patients were immediately treated with voriconazole. Two patients initially received amphotericin B; but this treatment had to be stopped because of acute renal toxicity. Finally, all patients were treated orally with 200 mg voriconazole twice a day for 12-14 weeks. After this combined treatment all patients were asymptomatic and there were no endoscopic or radiological signs of residual fungal disease. The only side effects were nausea in one and transient visual disturbances in 2 other patients. In the 4 patients presented and treated, voriconazole was shown to be effective and less toxic than amphotericin B in adjuvant treatment of invasive sphenoidal aspergillosis.

[Operation of chronic sphenoid sinusitis with endoscopic sinus surgery]

OBJECTIVE

To evaluate the method and treatment effect of endoscopic sinus surgery for chronic sphenoid sinusitis.

METHOD

Fifty cases, 84 sides of chronic sphenoid sinusitis patients were treated with endoscopic sinus surgery.

RESULT

In the follow-up of 6-12 months, 61 sides (72.62%) were cured; 13 sides (15.48%) were mended; 10 sides (11.90%) were ineffective; 74 sides were effective, the effectiveness rate were 88.10%.

CONCLUSION

Treatment with endoscopic sinus surgery is a safe, effective method with little pain for chronic sphenoid sinusitis.

An unusual presentation of sphenoid sinusitis with septicaemia in a healthy young adult

Streptococcus pneumonia and Haemophilus influenzae account for more than 50% of bacterial acute sinusitis. Isolated sphenoid sinusitis is a rare disease with potentially devastating complications such as cranial nerve involvement, brain abscess, and meningitis. It occurs at an incidence of about 2.7% of all sinus infections. There have been no previous reported cases of unilateral sphenoid sinusitis presenting as septicaemia in an otherwise healthy young immunocompetent adult.

Isolated inflammatory sphenoiditis with multiple unilateral cranial nerve palsies

Isolated sphenoidits is a rare entity that often presents with vague, non-specific symptoms. We present the case of a 36-year-old Middle Eastern man, who developed headache and a painful right eye. A diagnosis of acute sphenoiditis was made. Shortly afterwards, he developed diplopia due to isolated abducent nerve involvement. Within two months, the extent of cranial nerve involvement had increased to include cranial nerves II, III, and V. Subsequently, this was treated by functional endoscopic sinus surgical drainage and biopsy. Histology revealed inflammatory changes. The patient made a dramatic recovery post-operatively, with resolution in all symptoms.

Surgical consideration to optic nerve protrusion according to sinus computed tomography

OBJECTIVES

This study aimed to investigate the prevalence of optic nerve protrusion (ONP) and its clinical indicators by using sinus computed tomography (CT) scan.

STUDY DESIGN

Sinus CT scans of 260 consecutive patients with chronic inflammatory sinus disease were reviewed.

RESULTS

The prevalence of ONP in our study population was 28%. Nineteen percent of the optic nerves protruded into the sphenoid sinuses including indentation of the sinus wall (12%) and coursing through the sphenoid sinus (8%). In the presence of contralateral ONP and/or ipsilateral anterior clinoid process pneumatization, the chance of ONP occurrence was significantly higher (both P < 0.01). They were reliable indicators of ONP (R(2) = 0.47, P < 0.01).

CONCLUSIONS

ONP is a common anatomic variation observed in patients with chronic inflammatory sinus disease. To reduce optic nerve damage in surgeries, the presence of ONP according to sinus CT scans and the intraoperative findings should be carefully evaluated.

EBM RATING

C-4.

Rhinoplasty and endoscopic surgery for functional and inflammatory nasal/sinus disorders

The rhinoplastic surgeon when faced with nasal sinusitis has traditionally delayed aesthetic treatment of the nose, referring the patient to the ear, nose, and throat consultant until complete resolution of the inflammatory condition. Often, under such a scenario, the patient found the ear, nose, and throat procedure to be a traumatic experience that discouraged further surgery of an aesthetic nature. The advent of functional endoscopic sinus surgery has significantly modified the management of paranasal sinus disorders. This minimally invasive, sophisticated procedure can easily be combined with rhinoplasty. More recently, an endoscopic approach has been advocated for management of the septum and lower/middle turbinates. The authors call this functional endoscopic nasal surgery. Functional endoscopic nasal surgery allows a clearer view of the operative field (septum and turbinates), a more accurate correction of nasal obstruction, and better control of bleeding. Thus, endoscopic techniques permit the treatment of functional and inflammatory nasal disorders in a single stage, along with aesthetic improvement. Only the patient with severe sinusitis is unsuitable for combined therapy. The authors present their experience based on 72 consecutive cases of combined functional endoscopic sinus surgery/functional endoscopic nasal surgery with aesthetic rhinoplasty. Complications were minimal and functional failures were limited to 4 percent, whereas aesthetic outcomes remained uncompromised.

Extensive endoscopic sinus surgery from the viewpoint of out-patients in a metropolitan area

Extensive functional endoscopic sinus surgery (FESS) was assessed retrospectively from the viewpoint of out-patients on the basis of their responses to a postal questionnaire, particularly in the Tokyo metropolitan area. Seventeen patients were included in this study (six females and 11 males) with an age range of 22-70 years. All the patients had at least ethmoid sinusitis. Additionally, some patients had maxillary or sphenoid sinusitis or polyps obstructing the nasal cavities. The average operation time and blood loss were 36 minutes and 31 ml, respectively. Four patients had to travel more than one hour to reach home. All of them used the train for travelling to and from the hospital. 'Doctors' advice' was the most common reason for the decision to undergo this ambulatory surgery. Nine (53 per cent) had some unexpected problems post-operatively. The establishment of a care pathway may improve the outcome of extensive FESS on an out-patient basis.

Anatomic variations of the sphenoid sinus on computed tomography

Anatomic variations of the vital structures adjacent to the sphenoid sinus can be jeopardized during functional endoscopic sinus surgery (FESS). The knowledge of the size and extent of pneumatization of the sphenoid sinus (SS) is an important condition for adequate surgical treatment of its disease. The bony anatomic variations of SS as well as its relationship with adjacent vital structures were reviewed in this paper. The study was performed on 267 patients with a complaint of chronic or recurrent sinusitis. Computed tomographic (CT) scans were obtained upon completion of therapy. The evaluations of the sphenoid sinuses were regarded separately, so as 534 sides were examined. Especially bony anatomic variations as well as mucosal abnormalities of the sphenoid sinuses were examined. Pneumatization of the pterygoid process and anterior clinoid process were found in 39.7% and 17.2% of the patients respectively. Vidian canal protrusion was found in a total of 158 sides of which 60 were bilateral. These entities were encountered usually when pneumatization of the pterygoid process occurred. Carotid canal and optic canal protrusions were found in 5.2% and 4.1% of the patients respectively. Mucosal thickening, and polyps or cysts of sphenoid sinuses were detected in 20.6% and 4.5% of the patients respectively. There was a statistically significant correlation between pterygoid pneumatization and vidian canal protrusion (p < 0.001), and vs. foramen rotundum protusion (p = 0.004). While the optic canal protrusion was found significantly associated with the anterior clinoid pneumatization (p < 0.001), there was no statistically significant correlation between a carotid canal protrusion and anterior clinoid pneumatization (p = 0.250). Sphenoid sinus surgery is very risky, because of changing variations of the cavity. We are in the opinion that detailed data from CT scans of SS will enable the surgeon to interpret any anatomic variations and pathological conditions before initiation of the surgical therapy.

Does Helicobacter pylori play a role in upper respiratory tract inflammation? A case report

Persistent isolated inflammation of the sphenoid sinus, an entity that is not diagnosed very often, poses a challenge to clinicians and researchers alike. Its features tend to suggest that its etiopathogenesis is different from that of more common forms of chronic rhinosinusitis. We report the case of a 54-year-old woman who had a history of distressing chronic postnasal drip and a globus sensation with opacification of the sphenoid sinus. She was diagnosed with gastroesophageal reflux, and Helicobacter pylori was detected in her gastric contents and in the inflamed mucosa of the sphenoid sinus, as well. Complete symptom relief was achieved only after she had undergone surgical sphenoidotomy and treatment with anti-H pylori medication. We discuss the potential for this ubiquitous gastric bacterium to play a role in at least some forms of chronic sinonasal inflammation.

[Course and therapy of an invasive aspergilloma of the skull base in a non-immunocompromised patient]

Fulminant-invasive sinus aspergillosis affects immunocompromised patients and is usually lethal because of intracranial complications. Chronic-invasive and non-invasive types occur in non-immunocompromised patients. In these cases, intracranial extension is possible and life-threatening. The effective management of sinus aspergillosis requires early diagnosis by CT and histological classification, surgery, and if necessary, chemotherapy or steroids in case of allergy. Here we report a successfully treated case in a 29-year-old non-immunocompromised patient with chronic-invasive sinus aspergillosis. He presented a recurrent sphenoid sinus aspergillosis with destruction of the clivus and ophthalmoplegia. Diagnostic and therapeutic procedures are described.

Recurrent Escherichia coli meningitis associated with aspergillar sphenoidal sinusitis

Recurrent meningitis due to Escherichia coli is an extremely rare infection in adult patients. Most cases have been complications of neurosurgery. We report on the case of a 43-y-old man with 4 recurrent spontaneous episodes of E. coli meningitis related to aspergillar sphenoidal sinusitis. Surgical treatment of sinusitis cured the patient.

[Endoscopic transnasal approach in surgical treatment of ethmoid sphenoid diseases]

OBJECTIVE

To study the surgical experience of endoscopic sinus surgery for the patients with sphenoid sinus disease.

METHOD

Twenty-one patients of sphenoid sinus diseases were treated with endoscopy by nasal cavity and sphenoid sinus.

RESULT

During 3 months to four years following up, 20 patients were free from disease postoperatively, 1 patient underwent reoperation because of recurrence.

CONCLUSION

Nasal endoscope provide the clear visual field, and operation under nasal endoscope could less pain and minimize injury to normal tissue. Transnasal-sphenoidal endoscopic sinus surgery under local anesthesia seems to be a safe and valuable way.

Acute isolated sphenoid sinusitis

INTRODUCTION

Acute isolated sphenoid sinusitis is seen in fewer than 3% of all cases of sinusitis. It is frequently misdiagnosed because of its vague symptoms and the paucity of clinical findings. We report 2 cases of isolated acute isolated sphenoid sinusitis with unusual presentations.

CLINICAL PICTURE

Both patients presented with acute headache, eye pain and fever, and were provisionally diagnosed as meningitis. In 1 case, the symptoms were on the contralateral side of the sphenoid infection. Intracranial complications were also present.

TREATMENT

Treatment included intravenous antibiotics and endoscopic sphenoidotomy.

OUTCOME

Both patients recovered with no residual neurological disability.

CONCLUSION

Acute sphenoiditis usually presents with subtle symptoms and elusive physical findings and hence a high index of suspicion is necessary. Complications may arise due to the close proximity of important structures to the sphenoid sinus. Uncomplicated cases can resolve with optimal antibiotic therapy if diagnosed and treated early. Persistence or progression of disease with development of intracranial complications are indications for immediate surgical drainage.
