CONCLUSIONS: Paranasal sinus mucocoeles present most commonly with ophthalmic symptoms and signs. Patients with this condition are therefore highly likely to present initially to the ophthalmology department. [ncbi.nlm.nih.gov]

• Foul Smelling Discharge

  Figure 4 shows a radiological image of left maxillary mucocele in an adult patient with nasal blockage and foul smelling discharge. [intechopen.com]

• Postnasal Drip

  Cysts that put pressure on the mucosal lining of sinuses cause symptoms such as headache and periorbital or facial pain, and those that obstruct the ostium may cause paranasal sinus infection, nasal obstruction, postnasal drip, and nasal discharge, which [alliedacademies.org]

• Nasal Voice

  The patient may complain about nasal obstruction, nasal voice, proptosis, diplopia and headache. The affected frontal sinus will appear as a cloud with rounded, ovoid or smooth contours on the radiograph. [nasodren.com]

• Loss of Appetite

  He did not have any other symptom or sign such as runny nose, sneezing, epistaxis, facial swelling, loss of appetite or weight, diplopia, or decrease in visual acuity. [thritajournal.com]

• Facial Scar

  When used by surgeons familiar with endoscopic sinus surgery this has proved a safe and successful procedure that avoids facial scarring. [ncbi.nlm.nih.gov]

  If a wide marsupialization can be achieved by an entirely endoscopic approach there are a number of advantages, notably a lack of facial scarring in children and young adults. [scienceopen.com]

• Focal Neurological Deficit

  Pressure effects on the cranial nerves can result in sudden focal neurological deficits such as blindness if the cavernous part of the carotid sinus is involved laterally. [ejo.eg.net]

• Sinus Opacification

  These include diminished sinus volume with retraction and inward bowing of the maxillary sinus walls, downward bowing and thinning of the orbital floor and increased orbital volume, near-to-complete sinus opacification, lateral retraction of the uncinate [appliedradiology.com]

Abstract Several controversies still exist regarding the etiopathogenesis, diagnosis, and type of surgical treatment used in response to paranasal sinus mucocele. [ncbi.nlm.nih.gov]

Because of cranial nerve involvement, mucoceles in the posterior paranasal sinuses had a worse prognosis than those in the anterior paranasal sinuses. [ncbi.nlm.nih.gov]

Treatment and prognosis In general, drainage and marsupialisation of an affected sinus are sufficient. If large bony defects are present, reconstructive surgery may be necessary (e.g. of the orbital floor). [radiopaedia.org]

Prognosis The importance of accurate pretreatment evaluation and staging with paranasal sinus tumors is critical, the stage and type of the paranasal sinus tumor are the most important factors in determining the prognosis. [skullbaseinstitute.com]

Since dural invasion implies both a worse prognosis and a surgical resection not limited to the eroded bone, the goals of imaging focus on establishing the depth of skull base invasion (Kraus et al. 1992b; Shah et al. 1997). [78stepshealth.us]

Authors also looked for etiological factors. RESULTS: Cystic fibrosis was found in 6 cases out of 10. Others etiological factors were trauma and inflammatory process; one case was strictly idiopathic. [ncbi.nlm.nih.gov]

There are some disagreements over the etiology of the mucoceles ( 7, 8 ). [thritajournal.com]

The etiology is either embryologic or secondary to trauma or an infective process. [intechopen.com]

Various etiologies have been speculated and they have been categorized into obstructive and inflammatory causes. [ejo.eg.net]

Thorough discussions of anatomy and pathophysiology of a variety of frontal sinus diseases provide a background for in-depth chapters on aspects of both medical and surgical management. [books.google.com]

The pathophysiology is believed to be due to poor drainage of mucosal secretions from the obstructed sinus. [ejo.eg.net]

Pathophysiology of the mechanism of bone reabsorption produced by mucoceles is still obscure. [scielo.br]

The underlying pathophysiology may be caused by direct compression on the nerve lesions, nonperfusion of the blood vessels that lead to ischemic orbital nerve or inflammation in response to infection around the nerve. [transbiomedicine.com]

This complication can be prevented by taking care not to damage normal mucosa. Retention of healthy mucosa in the middle meatal area prevents adhesions from occurring. [entscholar.wordpress.com]

This places the other (combined) technique at a disadvantage and thereby prevents the detection of any possible significant association, even if there really is one. [elsevier.es]

Alternatively, frontal sinus osteoplastic approach with fat obliteration may be preferred inorder to prevent the collapse of the anterior wall.These procedures have significant surgical morbidities including scarring, cosmetic deformities and paresthesias [ispub.com]
