 D

Sublingual duct

Ans. C

Explanation:

Submandibular duct REF: Clinical surgery: Volume 9 Head and neck edited by Charles Rob, Rodney, Smith page 56 “The treatment of ranula constitutes a problem, owing to the technical difficulty of complete excision without damage to adjacent structures such as the submandibular duct”

Ranula:

A ranula is a sublingual swelling. Most consist of a mucus filled cyst that lies under the mucosa, just lateral to the frenulum. It is thought to be a retention cyst that arises from the obstruction of one of the several ducts draining the sublingual gland. It presents as an asymptomatic swelling of the floor of the mouth, but occasionally can get so large that it interferes with speech or eating. Treatment consists of uncapping and marsupialising it. Very occasionally, the ranula can penetrate through the mylohyoid muscle and into the neck, when it is known as a plunging ranula. This requires excision, as does a simple ranula if it recurs after uncapping. REF: Textbook of General and Oral Surgery by David Wray, David Stenhouse pahe 121

Minor mucous retention cysts develop in the floor of the mouth either from an obstructed minor salivary gland or from the sublingual salivary gland. The term `ranula’ should be applied only to a mucous extravasation cyst that arises from a sublingual gland. It produces a characteristic translucent swelling that takes on the appearance of a ‘frog’s belly’ (ranula). A ranula can resolve spontaneously, but many also require formal surgical excision of the cyst and the affected sublingual gland. Incision and drainage, however tempting, usually results in recurrence. REF: Bailey & Love’s 25th edition page 754


Q. 3

A ranula is most appropriately described by which of the following statements?

 A

It is a type of Epulis

 B

A form of thyroglossal cyst

 C

 D

A type of mucus retention cyst

Q. 3

A ranula is most appropriately described by which of the following statements?

 A

It is a type of Epulis

 B

A form of thyroglossal cyst

 C

A cystic swelling in the floor of mouth

 D

A type of mucus retention cyst

Ans. C

Explanation:

Ranula is a cystic swelling in the floor of the mouth due to the obstruction of one or more ducts of the sublingual gland.

It does not always represent a mucus retention cyst, it is more commonly a mucus extravasation cyst.

It is neither a type of Epulis nor a type of thyroglossal cyst.

Q. 4

Which of the following best represents `ranula’?

 A

A type of epulis

 B

A thyroglossal cyst

 C

Cystic swelling in the floor of mouth

 D

Forked uvula

Q. 4

Which of the following best represents `ranula’?

 A

A type of epulis

 B

A thyroglossal cyst

 C

Cystic swelling in the floor of mouth

 D

Forked uvula

Ans. C

Explanation:

Answer is ‘c’ ie Cystic swelling in the floor of mouth 

Ranula is a descriptive term used to describe a swelling in the floor of the mouth that resembles a frog’s belly. It is neither an epulis nor a thyroglossal cyst.

Ranula

– It presents as a transluscent bluish, swelling in the floor of the mouth, lying on one side of the midline.

– When the cyst enlarges to present in the neck it is known as plunging or deep ranula.

– Treatment consists of complete excision or marsupialization for large cyst.

[Note: Epulis is a non specific term used to describe a localized swelling of the gums.]

It is a type of thyroglossal cyst

 D

It is a type of mucus retention cyst

Q. 8

True regarding Ranula:

 A

It is also called as epulis

 B

It is a cystic swelling in the floor of mouth.

 C

It is a type of thyroglossal cyst

 D

It is a type of mucus retention cyst

Ans. B

Explanation:

 

Ranula

It is a thin walled bluish retention cyst.

Seen in the floor of mouth on one side of the frenulum.

It arises due to obstruction of duct of sublingual salivary gland.

It is almost always unilateral.

Clinical Features

  • Seen mostly in children and young adults.
  • Only complain—swelling in the floor of mouth
  • Cyst may rupture spontaneously but recurrence is common

 A

Retention cyst

 B

Extravasation cyst

 C

Edema of uvula

 D

Edema of floor of mouth

Ans. A

Explanation:

Ans. A i.e. Retention cyst

Bailey & Love (Surgery) states that ranula is an extravasation cyst, but CSDT (Surgey), Dhingra (ENT) & even internet references describe it as retention cyst.

Retention cyst

 B

Translucent swelling

Ans. D

Explanation:

Ans. is’d’  i.e., Arises from submandibular gland

Ranula

  • Ranula, also known as mucous retention cyst, is a type of mucocle found on the floor of mouth on one side of the frenulon.
  • It arises from sublingual salivary gland, due to obstruction of its duct and is almost always unilateral.
  • In occurs mostly in children and young adults.

Clinical features

  • Ranula is usually asymptomatic, and only complain isfluctuant swelling with a bluish translucent colour.
  • Swelling is painless unless it becomes secondarly infected.
  • Overlying mucosa is intact and ranula is not fixed.

Treatment

  • Surgical excision of both the gland as well as the lesion. Ranulas are likely to recur if the sublingual gland causing them is not removed with the lesion.
