Congenital atresia of the orifice of the submandibular duct:a report of 2 cases and review

Modern management and pathophysiology of ranula: Literature review

“…Many of the publications also contain details of treatments undertaken elsewhere prior to referral, and these have been included. Occasionally a postnatal ranula had been diagnosed as ductal atresia, 39,45 although with current knowledge, the real nature of these lesions is clear.…”

“…Simple incision and drainage was unsuccessful 17,19,28,43,44 except for perinatal oral ranulas, 16,26,27,45 of which 27% were successfully treated. The reason for this success is not apparent, although possibly the mucosal epithelium is more proliferative perinatally and sometimes establishes an epithelially lined tract before the wound closes.…”

Sialodochostomy as treatment for imperforate submandibular duct: A systematic literature review and report of two cases

“…The authors speculated that this might have been due to rupture of the sialocele during feeding. The majority of published reports attempted some form of sialodochostomy, ''unroofing,'' or ''marsupialization,'' i.e., creation of an opening from the salivary duct into the floor of mouth [2][3][4][5][6][7][8][9][10][11][12][13][14][15]. In most cases, this was accomplished by simple stab incision into the cyst wall or by excision of the imperforate duct papilla.…”

Congenital imperforate submandibular duct in a newborn

“…[1][2][3] Failure of canalization of the terminal end of the duct has been cited as the cause of this anomaly. 1 Mostly reported cases have been unilateral swellings manifesting at birth. Diagnosis is made primarily by physical examination, rarely magnetic resonance imaging is requested to outline ductal anatomy to diagnose duplication anomaly.…”
