Necrotizing sialometaplasia (NS) is a benign, ulcerative lesion, usually located towards the back of the hard palate. It is thought to be caused by ischemic necrosis (death of tissue due to lack of blood supply) of minor salivary glands in response to trauma. Often painless, the condition is self-limiting and should heal in 6–10 weeks.
A follow-up study of cleft children treated with vomer flap as part of a three-stage soft tissue surgical procedure. Scandinavian Journal of Plastic and Reconstructive Surgery, 11(1), 45–57. Maggiulli F, Hay N, Mars M, Worrell E, Green J, Sommerlad B (2014) Early effect of vomerine flap closure of the hard palate at the time of lip repair on ...
Due to the strong association with denture-wearing, the lesion tends to occur more in adults than children. There is no gender predilection. [1] In people who wear dentures 24 hours a day, its incidence is around 20%. Inflammatory papillary hyperplasia almost exclusively involves the hard palate, specifically the vault of the palate.
This is followed by a thorough clinical investigation including extra-oral and intra-oral hard and soft tissues. [5] It is sometimes the case that a diagnosis and treatment regime are possible to determine from history and examination, however it is good practice to compile a list of differential diagnoses. Differential diagnosis allows for ...
The hard palate is formed by the palatine process of the maxilla and horizontal plate of palatine bone.It forms a partition between the nasal passages and the mouth.On the anterior portion of the hard palate are the plicae, irregular ridges in the mucous membrane that help hold food while the teeth are biting into it while also facilitating the movement of food backward towards the larynx once ...
Tongue posture plays an important role in swallowing and dentofacial growth. In case of tongue thrust swallowing, the tip of the tongue can come against or between the dentition; the midpoint may be collapsed or extended unilaterally or bilaterally; or the posterior part of the hard palate. In these conditions, there are chances of abnormal ...
Submucous cleft palate can also occur, which is a cleft of the soft palate with a split uvula, a furrow along the midline of the soft palate, and a notch in the back margin of the hard palate. [12] The diagnosis of submucous cleft palate often occurs late in children as a result of the nature of the cleft. [13]
However, if diagnosis of congenital syphilis is delayed until Hutchinson’s triad is noted–among other signs and symptoms, such as nasal cartilage destruction (saddle nose), frontal bossing, joint swelling (Clutton joints), tibial thickening (Saber shins), hard palate defect–the damage is irreversible.
