Non-odontogenic cysts originate from tissues other than teeth and surrounding structures, such as the mucosal lining, salivary glands, connective tissue, or developmental remnants in the oral cavity. Unlike odontogenic cysts, which arise from dental tissues, non-odontogenic cysts emerge from various non-dental tissues and often present diverse clinical manifestations. Common examples of non-odontogenic cysts include the nasopalatine duct cyst, nasolabial cyst, and developmental cysts that form from epithelial remnants during embryonic development.

Cysts in orofacial regions were discussed. Key points include:
1. Cysts are pathological cavities lined by epithelium and filled with fluid/semi-solid material. Common types are odontogenic cysts like dentigerous and keratocysts.
2. Dentigerous cysts form between reduced enamel epithelium and tooth crown, associated with unerupted teeth. Keratocysts have high recurrence rates due to thin fragile lining.
3. Treatment options are marsupialization to shrink large cysts, and enucleation to remove the cyst lining along with the associated tooth/teeth.

This document discusses non-odontogenic cysts, which are cysts that arise from epithelial entrapments during embryonic development and are not derived from odontogenic epithelium. It describes several types of non-odontogenic cysts including fissural cysts like the nasopalatine duct cyst, pseudo cysts like the traumatic bone cyst, and soft tissue cysts like the thyroglossal cyst. Radiographic appearances and locations are provided for different cyst types.
A cyst is an epithelium-lined sac containing fluid or semisolid material. In the formation of a cyst, the epithelial cells first proliferate and later undergo degeneration and liquefaction. The liquefied material exerts equal pressure on the walls of the cyst from within. Cysts grow by expansion and thus displace the adjacent teeth by pressure. May can produce expansion of the cortical bone. On a radiograph, the radiolucency of a cyst is usually bordered by a radiopaque periphery of dense sclerotic bone. The radiolucency may be unilocular or multilocular. Odontogenic cysts are those which arise from the epithelium associated with the development of teeth. The source of epithelium is from the enamel organ, the reduced enamel epithelium, the cell rests of Malassez or the remnants of the dental lamina.

This document discusses and defines various radiolucent lesions that can occur in the mandible. It describes 7 common radiolucent lesions - radicular cyst, dentigerous cyst, odontogenic keratocyst, residual cyst, ameloblastoma, simple bone cyst, and central giant cell granuloma. For each lesion, it provides details on definition, clinical features, radiographic appearance, differential diagnosis, and management options. The goal is to aid in identifying and distinguishing these radiolucent lesions of the mandible.
The document discusses several types of non-odontogenic cysts that develop in the oral cavity. It describes nasopalatine duct cysts, which originate from remnants of the nasopalatine duct in the maxilla. These cysts typically appear as well-defined radiolucencies between the central incisors. Median palatal cysts and globulomaxillary cysts are also discussed, which develop from epithelial remnants during fusion of facial processes. Palatal cysts of newborns are extraosseous cysts that commonly appear on the hard palate of infants.
This document discusses malignant odontogenic tumors, including odontogenic carcinomas and sarcomas. It provides a classification system for odontogenic tumors including benign and malignant categories. Specific tumor types are described such as primary intraosseous carcinoma, ameloblastic fibro-odontoma, odontoma, calcifying odontogenic cyst, and their characteristic features, locations, radiographic appearances, and typical treatments. Radiographic images are also included to illustrate examples of compound odontoma, complex odontoma, and ameloblastic odontoma lesions.
Dentigerous cysts are odontogenic cysts that surround the crown of an impacted tooth. They are the most common type of developmental jaw cyst, making up 20% of all jaw cysts. Dentigerous cysts typically occur in males in the second and third decades of life, with the most common sites being the mandibular and maxillary third molars and maxillary cuspid areas. Radiographically, dentigerous cysts can appear as central, lateral, or circumferential expansions surrounding the crown of an unerupted tooth. Small cysts are usually treated with enucleation, while larger cysts involving bone loss require marsupialization.
1) Cysts are pathological cavities that can form in hard or soft tissues and may contain fluid, semisolid, or gaseous material.
2) Cysts are generally classified as intraosseous or soft tissue cysts, and epithelial or non-epithelial cysts.
3) Common intraosseous cysts include odontogenic cysts like dentigerous and radicular cysts arising from dental tissues, and non-odontogenic cysts such as nasopalatine duct cysts arising from other epithelial tissues.
The document provides information about dentigerous cysts, including their definition, characteristics, and pathogenesis. Some key points:
- Dentigerous cysts originate from the separation of the dental follicle from around the crown of an unerupted tooth. They enclose the crown and are attached to the cementoenamel junction.
- They most commonly occur in males in the first to third decades of life, associated with mandibular third molars or maxillary canines. Large cysts can cause bone expansion and displacement of teeth.
- Radiographically, they appear as well-defined radiolucencies surrounding the crown of an impacted tooth. Histologically, the lining is non-

This particular slides consist of- what is hypotension,what are it's causes and it's effect on body, risk factors, symptoms,complications, diagnosis and role of physiotherapy in it.
This slide is very helpful for physiotherapy students and also for other medical and healthcare students.
Here is the summary of hypotension:
Hypotension, or low blood pressure, is when the pressure of blood circulating in the body is lower than normal or expected. It's only a problem if it negatively impacts the body and causes symptoms. Normal blood pressure is usually between 90/60 mmHg and 120/80 mmHg, but pressures below 90/60 are generally considered hypotensive.
2. Congenital Cysts
Non-odontogenic cysts are pathological cavities or sacs that develop within the oral and maxillofacial regions,
characterized by their origin from tissues other than teeth and their surrounding structures.
Unlike odontogenic cysts, which arise from dental tissues like enamel, dentin, and dental follicles, non-
odontogenic cysts emerge from various tissues such as the mucosal lining, salivary glands, connective tissue, or
developmental remnants within the oral and maxillofacial complex.
These cystic entities often present diverse clinical manifestations and radiographic features, necessitating
thorough diagnostic evaluation and tailored management approaches for optimal patient care.
What's the contrast between odontogenic and non-odontogenic cysts? Odontogenic ones come from teeth-
related tissue in bone or gums, while non-odontogenic ones originate from different types
of tissue.
3. What is an example of a non-odontogenic cyst?
Nonodontogenic cysts of the jaws most
commonly encountered are;
PLEASE HELP ARRANGE
1. Defect of Stafne
2. Dentigerous cyst
3. Infected mandibular oral cyst
4. Keratocyst (keratocystic
odontogenic tumor)
5. Nasopalatine duct cyst
6. Periodontal cyst
7. Radicular cyst
8. Residual cyst
9. Simple bone cyst
5. What is an example of a non-odontogenic cyst?
Non-odontogenic cysts of the jaws most commonly encountered are the nasopalatine
duct canal cyst, nasolabial cyst, traumatic bone cyst, Stafne bone cyst, aneurysmal bone
cyst, and focal osteoporotic bone marrow defect.
6. Branchiogenic Cyst
A branchiogenic cyst, also known as a cervical lymphoepithelial cyst or a branchial cleft cyst, is a congenital developmental
anomaly that arises from remnants of the branchial arches during embryonic development. These cysts are typically located in
the neck or lower jaw region and are often found along the anterior border of the sternocleidomastoid muscle. CONGENITAL
Definition:
Branchiogenic cysts are cystic structures that result from the failure of the branchial apparatus to completely obliterate during
fetal development. They usually contain fluid or semi-solid material and can vary in size.
Diagnosis:
Diagnosis of a branchiogenic cyst involves clinical examination and imaging studies. A physical examination may reveal a soft,
fluctuant mass in the neck or jaw area. Imaging techniques such as ultrasound, CT scans, or MRI can provide more detailed
information about the location, size, and content of the cyst.
7. Branchiogenic Cyst
Location:Branchiogenic cysts are commonly found in the lateral part of the neck, along the
anterior border of the sternocleidomastoid muscle. They may also be found in the jaw
region, usually in the angle of the mandible.
It's important to note that if a branchiogenic cyst becomes infected, it may require antibiotic
treatment before surgical removal can be considered. As with any medical condition,
individual cases can vary, so consulting a healthcare professional for proper evaluation and
treatment recommendations is essential.
Treatment:The treatment of a branchiogenic cyst typically involves surgical removal. This
is done to prevent complications such as infection, abscess formation, and discomfort. The
cyst and its associated tract are carefully excised to ensure complete removal and prevent
recurrence. Surgery is usually performed by an ear, nose, and throat (ENT) surgeon or a
maxillofacial surgeon.
8.
9. Dermoid Cyst
A dermoid cyst is a growth of normal tissue surrounded by a sac. This tissue grows unexpectedly under the skin
or within the body.What It Is:
A dermoid cyst is like a skin-like lump containing various materials like fluid, hair, nerves, and even teeth.
Appearance:
Surface dermoid cysts look like small lumps on the skin. Some are deeper within the body.
Most dermoid cysts are congenital, and about 70% are found in children 5 years old or younger.
They can develop anywhere on the body, but dermoid cysts are most often found in the periorbital
lateral eyebrow area
10. INFORMATION
Dermoid refers to something that’s like skin. A
cyst is a lump or bump that may contain fluid or
other material. Most often, dermoid cysts contain
a greasy yellow material, but they may contain:
Bone.
Fluid.
Hair.****
Nerves.
Skin.
Sweat glands.
Teeth OR FLOOR OF MOUTH
11. Types of Dermoid Cysts:
Periorbital Dermoid Cyst:
Found near the eyebrow's outer edge.
Can alter bone shape over time.
Epibulbar Dermoid Cyst: On the eye's surface.
Intracranial Dermoid Cyst: Inside the brain.
Nasal Sinus Dermoid Cyst: Inside the nose.
Orbital Dermoid Cyst: Around the eye socket bones
*** OVARIES AND SPINE
.
Symptoms:
Many people have no symptoms, but growing cysts can cause issues. Symptoms depend on the cyst type. For
example:
Periorbital dermoid cyst can appear swollen and yellowish near the eyebrow, potentially changing bone shape.
Remember, while dermoid cysts might look like tumors, they're usually not harmful and often require surgical
removal.
12. DERMOID CYST CLOSING TOPIC
Who Gets It?
Dermoid cysts can affect anyone. They're often diagnosed in children (7 out of 10 cases) and sometimes at birth
(4 out of 10 cases).
Causes:
Dermoid cysts are present from birth due to improper skin layer growth during fetal development. They form
when skin cells and glands gather in a sac and continue producing fluid.
Treatment:
Surgery is often needed to remove a dermoid cyst since it won't disappear by itself.
Dermoid (Epidermal Inclusion
Cyst):
● epidermoid cyst,
● epithelial cyst,
● keratin cyst,
● sebaceous cyst, or milia.
T
14. Thyroglossal Duct Cyst
Thyroglossal duct cysts (TDCs) are congenital throat cysts.
Typically benign, often detected and treated in children under
10, occasionally in adults. Surgery is the common treatment,
with low recurrence after removal.
● Thyroglossal Duct Cyst Symptoms:
● Notable lump in the throat moving upward when
swallowing or sticking out the tongue.
● Soft, smooth, round cyst felt under the skin, akin to cookie
dough.
● Swelling and discomfort if infected.
● Cyst rupture, fluid oozing.
● Difficulty in swallowing.
15. Thyroglossal Duct Cyst Cancer Symptoms:
Uncommon cancer in adults.
● Slow-growing, often asymptomatic.
● Detected incidentally while treating other conditions like
goiters.
● Signs include growing hard lump in the throat,
● swollen lymph nodes, swallowing issues.
● During a baby's growth, the thyroid gland forms. Cells from
the tongue move to the bone supporting the tongue.
Normally, a path that helped this process closes, but in
cysts, it keeps fluid. We don't know why this happens.
16. Diagnosis & Tests for Thyroglossal Duct Cysts:
Throat examination.
Ultrasound to measure cyst size.
Diagnosis & Tests for Thyroglossal Duct Cyst
Cancer:
Often discovered during other treatments.
Confirmatory tests:
Fine needle biopsy: Extracting and analyzing
tissue.
CT scan: 3D X-ray images.
MRI: Clear images using magnets and radio
waves.
17. Management & Treatment:
Need for Removal:
Surgery suggested for infected or problematic cysts.
Surgery might be advised even without symptoms.
Cyst Removal Surgery:
Commonly performed Sistrunk procedure.
Involves incision, cyst removal, thyroglossal tract removal, and part of hyoid bone.
Recovery after Sistrunk Surgery:
One week return to school or work.
2-6 weeks before strenuous activity, especially heavy lifting.
Cancer Treatment:
TDC cancer may require Sistrunk procedure.
Check lymph nodes and thyroid.
Further surgeries if needed:
Total thyroidectomy (partial/complete thyroid removal).
Lateral neck dissection (lymph node removal).
Radioactive iodine treatment (to eliminate remaining cancer cells).
20. Nasopalatine Duct Cyst (Incisive Canal
Cyst)
Definition:
A nasopalatine duct cyst is a frequent non-tooth-related cyst during development. It's also called an incisive canal
cyst. It emerges from leftover embryonic parts of the nasopalatine duct. These cysts often form in the center of the
upper front jaw, close to the incisive foramen.
21. Treatment
Treatment for nasopalatine duct cysts involves removal through either a palatine or buccal
approach, and transnasal endoscopic marsupialization is also a possible method.
Recurrence is infrequent, with reported cases ranging from 0% to 11% among patients.

23. Palatine Papilla Cyst
● The cyst of the incisive papilla is an
uncommon variant of the nasopalatine duct
cyst.
● This entity is described as arising from
epithelial nests of the incisive foramen rather
than within the incisive canal.
● Usually not visible during roentgenographic
examination.
● May be either symptomatic or asymptomatic
● If enlargement involves erosion of the palatal
bone, a corresponding radiolucency may be
noted.
24. Nasolabial Cyst (Nasoalveolar Cyst)
Clinical Features:
● Swelling below or inside the NOSTRIL that
may present in the canine region.
● CANNOT SEE THIS CYST ON A
RADIOGRAPH, but may produce "cupping"
of underlying bone. NOT WITHIN BONE
(extra-osseous) so not visible on a
radiograph.
Treatment:
Enucleation (surgical excision). Excellent
prognosis.
A soft tissue cyst of the UPPER LIP (extra-osseous cyst) superficially located in soft tissue of the
upper lip that histologically develops from epithelial remnants from the inferior and anterior portion
of the nasolacrimal duct.
25. Globulomaxillary Cyst
Clinical Features:
Usually asymptomatic, but occasionally produces swelling
with or without pain. All regional teeth are vital. Occurs
within bone (Intra-osseous)
Histologic Features:
Consists of epithelial remnants where the globular &
maxillary processes are fused.
Radiographic Features:
Inverted PEAR-SHAPED radiolucency between the
maxillary lateral & canine roots.
Teeth are vital, but roots may be divergent.
Treatment: Enucleation without disturbing the teeth.
Excellent prognosis
An inverted "PEAR-SHAPED" radiolucency in bone between the roots of the maxillary lateral &
canine (often causes roots of the involved teeth to DIVERGE).
26. Median Palatal Cyst
MEDIAN PALATAL CYST-rare, but may occur anywhere along the MEDIAN PALATAL RAPHE,
usually in the HARD PALATE MIDLINE, posterior to the premaxilla (occurs in bone;
intraosseous). Clinically, this lesion presents as a firm, painless swelling. This cyst may represent
a more posterior version of a Nasopalatine Duct Cyst, rather than a separate cystic degeneration
of epithelial rests at the line of fusion of the palatine shelves.
27. Median Palatal Cyst
•Histologic Features: epithelial remnants in the
line of fusion between the palatine processes.
Appears as a soft, fluctuant or crepitant swelling
in the hard palate midline.
• Radiographic Features: well-demarcated
radiolucency in the midline of the hard palate.
• Treatment: Enucleation with an excellent
prognosis.
28. Median Alveolar Cyst
Rare, but occurs in the bony alveolus
(intraosseous) between the central incisors.
Distinguished from a periapical cyst by the fact
that the adjacent teeth are vital.
Treatment: Enucleation
