What is the most common congenital anomaly of orofacial structures?
Cleft Lip (CL) and Cleft Palate (CP).
What are the genetic causes of CL and CP?
Cleft lip and nose: failure of fusion of the median nasal process with the maxillary process;
CP: failure of fusion of the palatine processes.
Cause of Cleft of philantrum & alveolus
Failure in fusion of median nasal process
What environmental factors increase the risk for CL and CP?
Maternal epilepsy and certain drugs taken during pregnancy (e.g., Phenytoin, Diazepam, Steroids).
Which syndrome is associated with cleft lip, cleft palate, and retrognathia?
Pierre Robin Syndrome
Name some syndromes associated with CL and CP.
Van der Woude, DiGeorge, Stickler, Treacher Collins, and several trisomy syndromes (e.g., Patau, Edwards).
What is the difference between a complete and partial cleft lip?
A complete cleft lip extends up to the nose. / detachment from vomer, while. a partial cleft lip does not reach the nose. / attached vomer
Most common CL
Left side Cl
What are some problems associated with cleft lip (CL) and cleft palate (CP)?
Airway, Breathing, Swallowing, Dentition, and Speech.
At what stage of pregnancy can CL be diagnosed antenatally?
After 18 weeks of pregnancy.
After birth 1-2 months
No surgery
Feeding modified feeding bottles
What is the recommended timing for plastic surgery reconstruction for cleft lip, nose and hard palate ( muscle reconstruction)?
CL - 3 MONTHS
soft palate - 6
Hard palate- 12
After surgery 1-7 yrs
Feeding, dentition, speech aesthetics
After surgery frome 8- 10 yrs
Alveolar Bone grafting
Formation of thyroglossal cyst?
When thyroglossal tract don’t obliterate after birth —- secretion accumulation —- cyst formation
What is the common location of a thyroglossal cyst?
Midline ( subhyoid )
What type of crystals may a thyroglossal cyst contain?
Cholesterol crystals.
What movement is associated with the swelling of a thyroglossal cyst?
moves with deglutition (swallowing). Thus tongue protrusion
What is the main characteristic symptom of a thyroglossal cyst?
Moves with tongue protrusion
What is the primary treatment for a thyroglossal cyst?
Sistrunk’s operation (excision of cyst and thyroglossal tract, including the central portion of the hyoid bone).
What is a complication of a thyroglossal cyst if it becomes infected?
can develop into an abscess, leading to rupture. Leading to either fistula or sinus
Thyroglossal sinus vs fistula
Sinus - cyst connected to skin only
Fistula ( 2 opening ) - thyroglossal tract relation + skin
Thyroglossal cyst can lead to which cancer
Papillary thyroid cancer
Duodenal atresia
Congenital disease
absence of a portion of the duodenum due to the failure of fusion of the foregut with the midgut.
