Mucocele of the ethmoid sinus* (original) (raw)

A Primary Ethmoid Mucocele in a 9-Year-Old Child: A Case Report and Literature Review

Clinical Case Reports, 2020

A mucocele is a mucous-filled cavity in the paranasal sinuses due to obstruction or compression of neighboring structures by inflammatory processes, trauma, or prior surgery. It can be indolent, locally expanding, and destructive. Mucoceles are extremely rare in children. We report a nine-year-old boy with sudden-onset left orbital pain and proptosis. Computed tomography showed a well-defined soft tissue lesion originating in the left ethmoid sinuses, suggestive of a mucocele. The mass was marsupialized by endoscopic sinus surgery. Mucoceles should be a part of the differential diagnosis of a child presenting with proptosis. Imaging studies are helpful in establishing the diagnosis.

Optic Neuropathy due to an Ethmoid Mucocele: A Case Report and Literature Review

Case Reports in Ophthalmology, 2019

Mucoceles of the paranasal sinus commonly involve the frontal sinuses, the ethmoid sinuses, and rarely the maxillary or sphenoid sinuses. They often present with sinus pain or pressure, but rarely can present with more severe symptoms such as changes in mental status or vision due to expansion and invasion through the skull base or orbit. A 62-year-old male presented with optic neuropathy, a relative afferent pupillary defect with proptosis and lateral gaze palsy of the left eye. The patient was found to have a large mucocele extending from the left posterior ethmoid sinus into the left orbital apex. Urgent endoscopic sinus surgery was performed jointly between Oculoplastics and Otolaryngology. Post-operatively, the patient had improvement in diplopia, extraocular motion, and proptosis with stable vision. This case demonstrates the importance of early identification and intervention in a rare presentation of a sinus mucocele to prevent serious complications such as vision loss.

A giant mucopyocele of the ethmoidal sinus resulting in impeding orbital complications

Mucoceles are benign and slow-growing lesions of the paranasal sinus that develop following blockage of the sinus ostium. It slowly enlarges and fills the paranasal sinus completely. If the mucocele content is infected, the lesion is called a mucopyocele. Most of the mucoceles are found in the frontal and anterior ethmoidal sinuses. It may expand to the orbit, leading to ocular disorders. The clinical manifestations of the paranasal sinus mucocele depend on the vital structures affected and can be classified as rhinological, ophthalmologic, and neurologic symptoms and signs. Preoperative computed tomography scan and magnetic resonance imaging are helpful to identify the size, location, and extension of the mucocele of mucopyocele of the paranasal sinus. The primary treatment of the mucocele or mucopyocele is a surgical approach like endoscopic sinus surgery with marsupialization of the mucocele. In this case report, we describe a case of a giant mucopyocele with an extension into the orbit.

The Endoscopic Management of Ethmoid Mucocele with Orbital Extension

2017

Paranasal sinus mucocele represents a quite common pathologic entity, with many questions concerning the ethiology. Generally, the onset of obvious symptoms is delayed until complications appear, notably eye-related. We’ll report the case of ethmoido-orbital mucocele, successfully managed by endoscopic marsupialization, in order to accomplish the main goal: restoring ventilation and wide sinus drainage.

Orbital Apex Syndrome Secondary to Huge Primary Ethmoidal Sinus Mucocele: A Case Report

Cureus, 2023

Ethmoidal sinus mucoceles are benign expansile lesions that may progressively invade the orbit causing optic nerve compression and its nearby structures. We report a rare case of primary ethmoidal sinus mucocele instigating orbital apex syndrome. A 40-year-old man presented with right eye (RE) progressive blurring of vision with diplopia for 2 weeks. It was preceded by right-sided facial pain for 3 months. Clinical examination revealed RE proptosis with multiple cranial nerves palsy involving right cranial nerves II, III, IV, V, and VI, suggestive of right orbital apex syndrome. Magnetic resonance imaging (MRI) demonstrated right eye proptosis and right ethmoidal mucocele with intracranial and right intraorbital extension compressing the right medial rectus and optic nerve. The patient underwent an uncomplicated endoscopic sinus surgery resulting in a return to normal appearance and function post-operation. Thus, ethmoidal mucoceles are benign and curable with early recognition and intervention.

Fronto-ethmoidal mucoceles: a study of 25 cases

International Journal of Otorhinolaryngology and Head and Neck Surgery

mucoceles are the frontal and fronto-ethmoidal sinuses, although they can also be found in the maxillary and sphenoid sinuses. They cause slow, progressive expansion and dilatation of the sinuses, producing symptoms, such as headache, nasal obstruction, facial pain, decreased visual acuity, diplopia, displacement of the eyeball and facial edema. The diagnosis is based on the history, physical examination and radiological findings. Computed Tomography (CT) is the preferred imaging modality for mucoceles. Endoscopic endonasal ABSTRACT Background: Paranasal sinus mucoceles are quite rare and a comprehensive study regarding their incidence, presentations, management and complications is significantly lacking in our geographical area which led to our prospective study. Fronto-ethmoidal mucoceles are the most common expansile lesions of the paranasal sinuses. Methods: This is a prospective study of 25 cases of patients presenting with fronto-ethmoidal mucoceles in a tertiary care hospital in Ahmedabad. All patients were managed surgically through endoscopic approach. Results: The study comprised of 25 cases of fronto-ethmoidal mucoceles. The average age of the patients was 47.72 years with a range of 21-75 years. 16 patients (64%) were females. The most common involvement was of frontal sinus (16 cases, 64%). The most common presenting symptom was displacement of eyeball (68% cases). The most common presenting sign was proptosis, present in 68% cases. Endoscopic sinus surgery was the most commonly used modality of treatment of frontal mucocele and fronto-ethmoidal mucoceles (23 cases). In 2 cases combined approach surgery (endoscopic and external) was done. Conclusions: Mucoceles most commonly occur between 4 th to 7 th decades of life. In most cases no predisposing factor is identified. The diagnosis is based on the history, physical examination and radiological findings. CT is the preferred imaging modality for mucoceles. Endoscopic endonasal surgery is currently the most commonly used surgical approach.

Recurrent Posterior Ethmoid Mucocele with Sphenoid Sinus Extension: A Case Report

2020

Mucoceles are benign, expansile and encapsulated mass within a paranasal sinus. It is mostly found in the frontal sinus and less commonly in the posterior ethmoid and sphenoid sinus. We reported a case of 61-year-old lady with recurrent right posterior ethmoid mucocele with sphenoid sinus extension after 3-month from first endoscopic sinus surgery for removal of mucocele. Computed tomography scan showed larger right posterior ethmoid mucocele with sinus expansion and erosion of right lamina papyrecea. Second endoscopic sinus surgery was performed and symptoms of patient relieved. Mucocele of paranasal sinuses can cause various complications and can be removed surgically. Take note of recurrence and regular follow up must be done.

A Case of Acute Fronto-Ethmoido-Orbital Mucocele

Clinical Rhinology An International Journal, 2014

Mucoceles are thought to arise as a consequence of obstruction and inflammation. Frontoethmoidal mucocele can present with multiple symptoms that also include ophthalmic symptoms. Though benign, they have the tendency to expand by thinning the bony walls, displace and invade the surrounding structures by pressure and bony erosions. When it involves the orbit and expands, it may mimic benign growths primarily arising from orbit. We report an acute presentation of fronto-ethmoido-orbital mucocele as a result of hemorrhage into the mucocele. How to cite this article Sasindran V, Joseph A, Moosankutty S, Gautam A.

Endoscopic approach for a delayed post-traumatic ethmoidal mucocele: a technical note

British journal of neurosurgery, 2017

Delayed post-traumatic mucoceles are rare. We describe the surgical treatment of a post-traumatic ethmoidal mucocele with intra-orbital extension. A uninostril endoscopic endonasal approach (EEA) was performed. The access was contralateral to the lesion to provide a wider lateral view. After a large sphenoid and ethmoid sinuses opening, the collection was drained and the optic nerve precociously identified. The orbital roof was eroded and the frontal dura mater directly visible. The uninostril contralateral approach allows a good exposure of the lateral fields and is conservative towards the nasal mucosa. A favorable skull base anatomy is the prerequisite for its efficacy.

An ethmoid mucocele causing diplopia: A case report

Medicine, 2017

Mucocele is a disease lined primarily by epithelium, and occurs mainly when the sinus ostium is obstructed. We report a case of a 37-year-old man who presented with painless proptosis of the right eye and diplopia. The preoperative finding was mucocele of the ethmoid sinus. We performed endoscopic sinus surgery, which included uncapping of the anterior and superior wall of the mucocele. The mucocele was treated safely and effectively without touching the medial orbital wall. Clinicians should note that minimally invasive surgery to remove ethmoid mucoceles is relatively straightforward and can prevent the various complications associated with these lesions.
