Endoscopic sinus surgery for orbital subperiosteal abscess secondary to sinusitis.

Subperiosteal orbital abscess (SPA) is a serious complication of paranasal sinusitis, which can lead to blindness or even death. A quick response is necessary as this condition is treatable. Early surgical intervention is indicated if there is risk of visual loss, or if no improvement is observed within 48 hours of starting medical therapy. Three patients with orbital SPA secondary to sinusitis treated successfully by Functional Endoscopic Sinus Surgery (FESS) are presented in this case series. The surgical indications were impending visual loss with an abscess and cellulitis impinging on the optic nerve in one child and in the other two patients, a lack of clinical response within 48 hours after starting systemic antibiotic. CT scans, nasal endoscopy, and ophthalmologic examinations are mandatory during the evaluation process. The advantages of FESS in these patients were the avoidance of external ethmoidectomy and its external facial scar, an early drainage of the affected sinuses, SPA, and the eradication of the disease from the fronto-ethmoidal region leading to an enhanced recovery and a reduced hospital stay. FESS is also a safe, convenient and minimally invasive procedure in patients presenting with serious complications of sinusitis.

[Revision endoscopic sinus surgery on chronic sinusitis and polyps].

OBJECTIVE: To study the indications, surgical landmarks, surgical significance, complications and operative avoidance of revision endoscopic sinus surgery on chronic sinusitis and polyps. METHOD: We performed revision endoscopic sinus surgery on 112 cases of chronic sinusitis and polyps under controlled hypotension anaesthesia by using the Messerklinger technique and Stryker debrider. RESULT: 89 cases were successful and 17 unresolved, 6 failed, all the complications consist of cerebrospinal fistula in one, orbital hematoma in four, increased tearing in three and profuse bleeding in 6 patients. CONCLUSION: Revision endoscopic sinus surgery was advised in case of sinuous obstruction caused by uncontrolled lesions under postoperative care, which can do good for adhesion and obstruction except nasal polyposis. The remanet of the middle turbinate and the upper arch of choana were helpful operative landmarks. Preoperative CT scan decrease the complications.

[Successful treatment of Cushing disease with the sphenoid sinus of conchal type: usefulness of inferior petrosal sinus sampling and STEALTH navigation system: a case report].

We report a case of Cushing disease whose microadenoma was not identified by MRI with dynamic study and whose sphenoid sinus was conchal in type. Venous sampling test in the bilateral inferior petrosal sinus demonstrated ACTH hypersecretion on the right side. The patient underwent transsphenoidal surgery. A poorly pneumatized sphenoid sinus was drilled effectively, guided by the STEALTH navigation system. After the first operation, the patient's serum ACTH concentration was still high, suggesting that tumor removal was incomplete. Then she underwent the second operation and the residual tumor was completely removed with the assistance of the STEALTH navigation system again. Postoperatively, her serum ACTH concentration dropped below 5 pg/ml. In this case, inferior petrosal sinus sampling was extremely helpful for the diagnosis of Cushing disease, and operations were able to be performed safely using the neuronavigation system in drilling of the incompletely pneumatized sphenoid sinus.

[Peroperative sinus arrest in a patient with sick sinus syndrome (apropos of a case)].

A sinus arrest occured during a surgical intervention in a patient suffering from a sinus nodal dysfunction. The Fentanyl acetate used as an analgésic, seems to have played an important role in the genesis of the accident, depressing sinusal and junctional automatisms. Though unusual, this complication leads to a further investigation in preoperative period for a possible sinus nodal dysfunction in order to anticipate an extreme preoperative bradycardia (sino atrial block) treated with intravenous administration of isoprenaline. Intraveinous atropine test is a simple preoperative technique of research in front all unexplained sinus bradycardia.

[Effect of a depressant drug on the recovery time of the sinus. Attempt of application to the diagnosis of sinus dysfunctions].

The authors have studied the effect of a depressant drug, 71247 or piprofurol, on the recovery time of the sinoatrial node after rapid electrical stimulation of the atrium (CSRT). 72 patients, divided into three groups, underwent the test: 14 patients with documentary evidence of sinus dysfunction; 48 patients in whom a sinus disorder was suspected, and 10 controls. As a general rule, the sinus recovery time was found to be significantly prolonged in the patients as compared with the controls. The authors have applied this test to the diagnosis of latent sinus dysfunction, categorising three different degress of RESA values: normal (less than or equal to 550 ms), average (between 550 and 1,000 ms), and prolonged (greater than 1,000 ms). In 6 patients from group one and seven from group two, the post-stimulatory pause was normal or average before the test, and prolonged after the injection of 71247; on the other hand the test did not give evidence of any prolongation of the pause in the controls. In this way a dynamic pharmacological test of depression brings and interesting slant on the diagnosis of disorders of the sinus.

Conversion of atrial flutter to sinus rhythm by carotid sinus pressure.

Conversion of atrial flutter to normal sinus rhythm via carotid sinus stimulation by manual pressure is not a well-known phenomenon. Two cases of atrial flutter in which carotid sinus pressure restored the sinus rhythm are presented. Since this procedure is usually benign, it is recommended that it be tried on patients having atrial flutter with fast ventricular rate accompanied by hemodynamic decompensation. This may be particularly useful if the patient has been receiving digoxin, that is, when cardioversion may become potentially problematic. Electrophysiological mechanisms of conversion of atrial flutter to sinus rhythm are discussed.

The role of functional endoscopic sinus surgery in the management of recurrent sinus barotrauma.

Sinus barotrauma occurs when an individual is unable to equilibrate the pressure within his sinuses with atmospheric pressure. Aviators affected by recurrent sinus barotrauma are unfit to fly until the underlying cause is established and treated. While most cases result from intranasal pathology, a significant number are the result of sinus pathology or anatomical abnormalities. This latter group have been difficult to manage in the past but the advent of computerized tomography and the Hopkin's rod endoscope have allowed them to be operated on with precision and safety. Complications of this treatment are uncommon and the aviator has usually been able to resume full flying duties after undergoing a decompression test. In our experience it is rare for an aviator who has passed a decompression test to have further episodes of sinus barotrauma.

[New methods of diagnosis and treatment of paranasal sinusitis with "IaMIK" sinus catheters].

A new method for the diagnosis and treatment of PNS has been designed. The devices are named sinus-catheters YAMIK and consist of elongated flexible body with two inflatable vessels and three passages. Two of the passages have separate outlets into the vessel cavities and serve for their inflation. The third, working passage, opens on the body surface between the vessels and has an adaptor on the other end. Also a glass model of nasal sinuses has been developed. On the model YAMIK the procedure performs as follows: sinus catheter is inserted into the nasal cavity, the nostril and rhinopharynx are sealed off by inflating the vessels, a syringe is connected to the adaptor of the working passage. It creates controlled negative pressure in the nasal cavity, and this makes pathological secretion come out of the paranasal sinuses through their natural openings. After the evacuation of the pathological contents, medicine is introduced into the sinuses. This glass model is helpful in understanding the principle of YAMIK procedure which provides a good opportunity to evacuate pathological secretion from PNS through natural ostia and introduce medicine into the PNS.

Recovery of non-invasive Aspergillus sinusitis by endoscopic sinus surgery.

No previous data regarding non-invasive Aspergillus sinusitis (NIAS) treated by endoscopic sinus surgery (ESS) has stated any relevance to pre-operative evaluations, disease entities, and the reversibility of symptoms and the sinus mucosa. This prospective study of 31 patients with NIAS and treated by ESS (Strammberger's method) was designed to tackle the above problems. All patients were followed post-operatively by endoscopy once a week. The most refractory symptom was post-nasal dripping. The other symptoms such as foul odour showed progressive improvement by the second post-operative week. Prolonged saccharin time and disease history longer than two years showed the warning signs of a poor recovery. Most patients belonged to the chronic indolent sinusitis group with 55.5% having a complete recovery within the 9th to 12th post-operative weeks. Most patients of allergic Aspergillus sinusitis manifested a recurrent course within months following a post-ESS silent period. All patients of aspergilloma completely recovered prior to the 8th post-operative week.

Subdural empyema and blindness due to cavernous sinus thrombosis in acute frontal sinusitis.

In this era of antibiotics, the complications of acute sinusitis are much less frequently encountered. Although orbital complications are most common, intracranial complications carry a high rate of mortality and morbidity. We describe a case of acute frontal sinusitis with subdural empyema and blindness due to cavernous sinus thrombosis and carotid artery thrombosis with a discussion of treatment of these complications and the etiology of blindness in sinusitis.

Anatomic variations of the paranasal sinuses: CT examination for endoscopic sinus surgery.

Chronic rhinosinusitis endoscopic surgery requires an accurate evaluation of diseases and paranasal sinus anatomic variations. This study aims to show the main anatomical variations in the ostiomeatal complex and paranasal sinuses which are usually depicted by computed tomography (CT). CT scans obtained 2 mm thickness in axial and coronal plane from a series of 200 patients with chronic sinusitis were examined to determine the prevalence of anatomic variants. Anatomical variations determined were supraorbital recess in 6%, concha bullosa in 30%, sphenomaxillary plate in 17%, infra-orbital ethmoid cells (Haller's cells) in 6%, spheno-ethmoid cells (Onodi's cells) in 12%, pneumatization of the anterior clinoid process in 6%, carotid artery bulging into the sphenoid sinus in 8%, pneumatization of the uncinate process in 2%, paradoxical curvature of the middle turbinate in 3% and septal deviation in 36%. Level difference between the ethmoid roof and nasal vault was an average of 8 mm in right side and 9.5 mm in left side. Awareness of these different variations will help the rhinologic surgeon in his orientation during endoscopic surgical procedures.

Frontal sinus fractures: computed tomography evaluation of sinus obliteration with lyophilized cartilage.

Allogenic lyophilized cartilage has been proven clinically to be a reliable material for obliteration of the frontal sinus without the limitations of donor site morbidity and the prolongation of the operation time produced by autogenic grafting. The long-term behaviour of the implanted material is of paramount importance for the success of the obliterative technique. This survey included 51 trauma patients on whom obliteration of the frontal sinus with lyophilized cartilage was performed. The fate of the lyophilized cartilage graft was evaluated from computed tomography imaging of the obliterated frontal sinus. No radiological sign of mucocele formation or inflammatory disease was noted. Bone density measurement of the obliterated sinus and the adjacent trabecular bone was calculated. The patient population was distributed into four groups (0-2, 2-4, 4-6, > 6 years) according the postobliterative time. The bone density of the implanted lyophilized cartilage was accentuated from group 1 to group 4 when compared with the bone density of the trabecular bone. This shows the long-term tendency of lyophilized cartilage graft to osseous substitution.

Prematurely detected traumatic carotid-cavernous sinus fistula, by means of unintentional contralateral inferior petrosal sinus catheterization: bilateral jugular bulb oxygen saturation findings.

A traumatic carotid-cavernous sinus fistula (CCSF) was prematurely suspected following the detection of arterial-like hemoglobin oxygen saturation values, sampled from a catheter placed for cerebrovenous monitoring. A high-resolution scan of jugular foramina revealed that the catheter tip had been unintentionally placed in the inferior petrosal sinus, contralateral to the CCSF, instead of in the superior jugular bulb. Jugular bulb hemoglobin oxygen saturation (SjO2), ipsilateral to CCSF, later approached arterial hemoglobin oxygen saturation (SaO2) values.The possibility and consequences of unintentional catheterization of the inferior petrosal sinus, and of extracerebral contamination of blood in the jugular bulb due to blood in the inferior petrosal sinus, are discussed. We also discuss the reliability of SjO2 monitoring in the present CCSF case.

[Physiology of the sinuses. Physiopathology of sinusitis].

Ventilation and drainage are the two essential intrinsic functions of the sinus. Both of them are dependent upon the permeability of the ostium, whose caliber is extremely variable with respect to anatomical factors, and dynamic factors associated with the vasomotricity of the mucous membrane. In many subjects the ostial permeability is precarious, thus explaining the frequency of inflammatory sinus reactions. These are due, as the level of the middle ear, either to a transostial inoculation of pathogenic germs creating a microbial sinusitis, or to an ostial obstruction responsible for a hypoxia, a hypercapnia, and a local depression creating a a vacuo sinusitis. The second situation leads to conditions that are favorable for the development of the first and vice versa.
