What causes a cyst in the maxillary sinus?
The mucous retention cyst of the maxillary sinus (MRCMS) is a benign and self-limiting injury, resulting from the leakage of mucus within the sinus mucosa due to ductal obstruction 4, 12. It has been suggested that MRCMS is of non-odontogenic origin, since it may also occur in dentate and edentulous patients.
What does it mean to have a cyst in your sinus?
A maxillary sinus retention cyst is a lesion that develops on the inside of the wall of the maxillary sinus. They are often dome-shaped, soft masses that usually develop on the bottom of the maxillary sinus. Fortunately, a retention cyst of the maxillary sinus is a benign lesion, or non-cancerous.
How do you treat maxillary sinus cyst?
Generally, treatment includes enucleation of the cyst and/or surgical excision, including endoscopic observation in some cases. Long-term multidisciplinary postoperative patient observation should be performed, especially in cases with high recurrence.
What problems can a sinus cyst cause?
Most mucous retention cysts (MRC) are asymptomatic2; however, when they cause symptoms like headache, periorbital or facial pain, repeated infections of the paranasal sinuses, and/or nasal obstruction, surgical treatment may be necessary3.
Are maxillary sinus cysts common?
Maxillary sinus retention cysts (MSRCs) are very common and most of them are asymptomatic and incidentally found on radiographs. Nevertheless, a few of them increase in size and cause symptoms by obstructing natural ostia of the maxillary sinus (MS) [1].
Is maxillary sinus cyst painful?
Retention cyst of the maxillary sinus is a benign lesion produced from obstruction of a seromucous gland or duct. It is mostly asymptomatic but sometimes is accompanied by facial pain, headache, nasal obstruction, and other symptoms.
Can a maxillary cyst be cancerous?
Malignant tumours of maxillary sinus are rare accounting to only 1.5% of all head and neck cancers [1]. Despite of their statistically low incidence, these neoplasms have an overall grave outlook [2]. The most common risk factors for maxillary sinus cancer are smoking and history of chronic sinusitis.
Can a maxillary cyst cause pain?
Abstract. Retention cyst of the maxillary sinus is a benign lesion produced from obstruction of a seromucous gland or duct. It is mostly asymptomatic but sometimes is accompanied by facial pain, headache, nasal obstruction, and other symptoms.
Can maxillary sinus cyst cause headaches?
We report the case of a patient with a dentigerous cyst in the maxillary sinus presenting as two months of intermittent, unilateral, pressure-like headaches. The diagnosis was suspected after an upright Waters’ projection radiogram and confirmed histologically after surgical removal.
Can sinus cyst cause eye problems?
Patients with cysts of the maxillary sinus may present to the ophthalmologist with proptosis, enophthalmos, diplopia, ptosis, epiphora, and, rarely, decreased visual acuity.
