As their name suggests, they are basically mucus-lined cysts and they can also occur in the paranasal sinuses, most commonly the frontal sinuses, the frontoethmoidal region, and the maxillary sinus. Sphenoid sinus involvement is extremely rare. When the lumen of the vermiform appendix of the intestine gets blocked due to any factor, a mucocele can also form there. Variations
A variant of a mucocele is found on the palate, retromolar pad, and posterior buccal mucosa. Known as a "superficial mucocele", this type presents as single or multiple vesicles and bursts into an ulcer. Despite healing after a few days, superficial mucoceles recur often in the same location. Other causes of bumps inside lips are aphthous ulcer, lipoma, benign tumors of salivary glands, submucous abscesses, and haemangiomas. Diagnosis
Microscopically, mucoceles appears as granulation tissue surrounding mucin. Since inflammation occurs concurrently, neutrophils and foamy histiocytes usually are present. On a CT scan, a mucocele is fairly homogenous, with an attenuation of about 10-18 Hounsfield units. Classification
Both mucous retention and extravasation phenomena are classified as salivary gland disorders. Treatment
Some mucoceles spontaneously resolve on their own after a short time. Others are chronic and require surgical removal. Recurrence is possible, thus the adjacent salivary gland may be excised as a preventive measure.Several types of procedures are available for the surgical removal of mucoceles. These include laser and minimally invasive techniques, which means recovery times are reduced drastically.Micromarsupialization is an alternative procedure to surgical removal. It uses silk sutures in the dome of a cyst to allow new epithelialized drainage pathways.
This study found that risk factors such as low education, low income cut off, taking antidepressants, and low social support are all factors that contribute to the higher percentage of these population in developing PPDS. Specifically, indigenous mothers had the most risk factors then immigrant mothers with non-indigenous Canadian women being closer to the overall population. South America
A main issue surrounding PPD is the lack of study and the lack of reported prevalence that is based on studies developed in Western economically developed countries. In countries such as Brazil, Guyana, Costa Rica, Italy, Chile, and South Africa there is actually a prevalence of report, around 60%. In an itemized research analysis put a mean prevalence at 10-15% percent but explicitly stated that cultural factors such as perception of mental health and stigma could possibly be preventing accurate reporting. The analysis for South America shows that PPD occurs at a high rate looking comparatively at Brazil (42%) Chile (4.6-48%) Guyana and Colombia (57%) and Venezuela (22%). In most of these countries PPD is not considered a serious condition for women and therefore there is an absence of support programs for prevention and treatment in health systems. Specifically, in Brazil PPD is identified through the family environment whereas in Chile PPD manifests itself through suicidal ideation and emotional instability. In both cases most women feel regret and refuse to take care of the child showing that this illness is serious for both the mother and child.
