XEROSTOMIA

Xerostomia Xerostomia (dry mouth) Is not a disease but a symptom caused by many factors.

Function of Saliva Lubrication Speech Eating Antibacterial action Buffering action: tooth remineralization Retention of removable denture

Symptoms & Signs Symptoms: Oral dryness (most common) Halitosis Burning sensation Loss of sense of taste or change taste Difficulty in swallowing Tongue tends to stick to the palate Decreased retention of denture

Symptoms & Signs Signs Angular cheilitis Rampant caries: cervical or cusp tip Periodontitis Candidiasis Saliva pool disappear glossitis

Management Surgical Ligation Of duct like Parotid duct Repositioning of Duct like Submandibular , Parotid S Gland Excision of Submandibular Gland

Mucocele

MUCOCELE It is a tissue swelling composed of pooled mucus that escapes into the connective tissue from several excretory ducts

Mucocele When salivary duct is severed the acinar cells will continue to secrete saliva into the severed duct. At the site of the cut/severance the secretory product escape into the connective tissue forming a pool of mucus that distends the surrounding tissue

Mucocele

Mucocele ETIOLOGY: Minor glands of the lip are most prone to severance as a result of injury or biting the mucosa. Intra oral minor salivary gland can also be effected as result of some irritation as well.

CLINICAL FEATURES Mostly encountered in children and young adults. Two third of the Mucocele occur in the 3rd decade of life. Both males and females are effected equally. SITE: mucosal surface of the lower lip buccal mucosa floor the mouth ventral surface of the tongue and palate Clinical appearance of the Mucocele depends on its location within the submucosa

CLINICAL FEATURES More superficial zones of mucous extravasations presents a fluctuant mass with bluish translucent appearance. Patient usually feels the Mucocele and the fluctuation in its size Pain is quite rare . Initially the Mucocele are well circumscribed but with repeated trauma they become nodular ,more diffuse and firm on palpation.

HISTOPATHOLOGY: Underlying pool of mucin distends the surface epithelium. The mucin is walled of by the rim of granulation tissue or in long standing cases by condensed collagen. An epithelial lining is lacking The mucinous material basophilic or acidophillic and contains neutrophils and large oval foam cells the histocytes . The base of the mucocele will reveal feeder duct. Long standing mucoceles will show acinar degeneration with fibrosis and minimal inflammation

HISTOPATHOLOGY:

TREATMENT: Minor salivary gland mucocele will not resolve on its own it must be surgically excised. To minimize the chances of recurrence the feeder gland should also be removed.

Mucus retention cyst

Mucus retention cyst It is a swelling caused by an obstruction of a salivary gland excretory duct resulting in an epithelial lining cavity containing mucus. Mucus retention cyst is sometimes also referred as Sialocyst.

Mucus retention cyst The mucus retention cyst is lined by epithelium and rarely occur in the major salivary gland, when they do occur they are multiple i.e. poly cystic disease of the parotid gland

Mucus retention cyst

Mucus retention cyst CLINICAL FEATURES: Encountered in adults from 3rd -5th decade. The lesion is painless and fluctuant and bluish in appearance. SITE: Parotid cysts are located in the superficial lobe as fluctuant well defined mass. Floor of the mouth is the most common place. -Lip -Buccal mucosa

Mucus retention cyst HISTOPATHOLOGY: The epithelium of the cyst is stratified cuboidal or columnar duct like epithelium. The cytoplasm in the of these cells is either clear or eosinophlic and my show some features mucous differentiation 70% of these cyst are unilocular rest of the 30% have multilocular pattern.

Mucus retention cyst TREATMENT: Simple excision is the treatment of choice with caution of rupturing the cystic sacs. Recurrence is rare.

Ranula

Ranula Is a term used for mucoceles that occur in the floor of the mouth. The name is derived form the word rana, because the swelling may resemble the translucent underbelly of the frog.

Ranula

Ranula

Ranula Although the source is usually the sublingual gland, may also arise from the submandibular duct or possibly the minor salivary glands in the floor of the mouth.

Ranula Presents as a blue dome shaped swelling in the floor of mouth. They tend to be larger than mucoceles & can cover floor of the mouth & elevate tongue. Located lateral to the midline, helping to distinguish it from a midline dermoid cyst.

Plunging or Cervical Ranula Occurs when spilled mucin dissects through the mylohyoid muscle and produces swelling in the neck. Concomitant floor of the mouth swelling may or may not be visible.

Plunging or Cervical Ranula

Ranula Treatment Marsupialization Sublingual gland removal via intraoral approach
