Study Notes
Orofacial Clefts
- Cleft lip: Failure of fusion between medial nasal processes and maxillary processes during the 6th and 7th week of intrauterine life.
-
Incidence:
- 45% cleft lip and palate together.
- 30% isolated cleft palate.
- 25% isolated cleft lip.
- 80% unilateral cleft lip.
- 20% bilateral cleft lip.
- 70% unilateral cleft lip on the left side.
- Cleft lip and palate more common in males.
- Isolated cleft palate is more common in females.
Clinical Picture
- Failure of contact between soft palate and pharyngeal wall.
- Feeding and swallowing problems.
- Speech: hypernasal voice.
- Respiratory difficulty: Asphyxia.
- Psychosocial difficulty.
- Dental abnormality: missing, supernumerary teeth, microdontia, macrodontia, hypoplasia of enamel, and malocclusion.
Veau's Classification of Cleft Lip
- Class I: Unilateral notching of the vermilion border doesn't extend into the lip.
- Class II: Unilateral notching involving the lip only, not extending to the base of the nose (incomplete cleft).
- Class III: Unilateral complete cleft involves the lip and floor of the nose.
- Class IV: Bilateral cleft notching or complete cleft.
Cleft Palate
- Medial nasal processes merge to form the primary palate.
- Palatine shelves fuse to form the secondary palate.
- Fusion between primary and secondary palate starts anteriorly (8 weeks) and progresses posteriorly to completion at 12 weeks.
Veau Classification of Cleft Palate
- Class I: Bifid uvula.
- Class II: Cleft in soft and hard palate not extending beyond the incisive foramen (incomplete).
- Class III: Complete cleft extending in soft and hard palate, passing unilaterally through the alveolar process.
- Class IV: Complete bilateral cleft involving soft and hard palate and alveolar processes on both sides of the premaxilla, leaving it free and mobile.
Double Lip
- A redundant fold of tissue partially covers the right anterior maxillary teeth.
- Types: Congenital or Acquired: may be a component of Ascher syndrome or result from trauma or oral habits.
Tongue Anomalies
Macroglossia
- Enlarged tongue.
- Causes: Congenital malformation or acquired disease.
-
Clinical Picture:
- Noisy breathing, drooling of saliva, difficulty in eating and speaking.
- Crenated lateral border of the tongue, ulceration, and necrosis.
- Open bite, mandibular prognathism, and asphyxia in severe cases.
Congenital Causes of Macroglossia
- Lymphangioma and hemangioma.
- Down syndrome: papillary, fissured tongue.
- Neurofibromatosis: multinodular appearance.
- Beckwith-Wiedemann syndrome: Visceral tumors like adrenal carcinoma, hepatoblastoma, and kidney tumors.
Acquired Causes of Macroglossia
- Amyloidosis: Deposition of abnormal protein in tissues.
- Hemifacial hyperplasia: Unilateral tongue enlargement.
- Edentulous cases.
- Tumors.
Microglossia
- Isolated or syndrome-associated.
- Associated with cleft palate, micrognathia, and missing lower incisors.
- Abnormally small tongue associated with constricted mandibular and maxillary arch.
Ankyloglossia (Tongue Tie)
- Short lingual frenum.
Lingual Thyroid Nodule
- Asymptomatic to large mass at the dorsum of the tongue in the area of the foramen cecum.
- Primitive thyroid nodule.
- Diagnosed with thyroid scan, MRI, and CT scan.
- Incisional biopsy is avoided due to the risk of hemorrhage.
Fissured Tongue (Scrotal Tongue)
- Burning sensation and associated with Mekerson Rosenthial syndrome.
Geographic Tongue
- Areas of atrophy and hypertrophy of tongue papillae.
Hairy Tongue
- Marked elongation and brown staining of the filiform papillae, resulting in a hairlike appearance.
Varicosities (Sublingual Varix)
- Abnormal dilated, tortuous veins.
- Common in old age.
Fordyce Granules
- Sebaceous glands that occur on the oral mucosa.
- Incidence: More than 80% of the population.
- Considered normal anatomic variation or ectopic tissue.
Clinical Features of Fordyce Granules
- Multiple yellow or yellow-white papules.
- Site: Buccal mucosa (common) and lateral portion of the vermilion of the upper lip.
- Histopathology: Multiple sebaceous glands below the surface epithelium.
Exostoses
Torus Palatinus
- Localized bony protuberances arising from the cortical plate.
- Benign condition common in adults.
- Site: Palatal vault.
- Dental complication: Fitting of denture.
- Histopathology: Mass of dense lamellar bone with a small amount of fibro-fatty marrow.
Torus Mandibularis
- Bony protuberances arising from the inner aspect of the mandible.
