What is Risdon incision?

The Risdon approach is a technique for reducing the condylar neck and subcondylar fractures that is easy to perform and easy to learn. Its value in the reduction of mandibular condyle fractures should be emphasized.

What are the different approaches to the angle of mandible?

The three surgical approaches used were intra oral, transbuccal and extraoral (submandibular) approach.

What is submandibular incision?

Submandibular Approach. The mandible can be exposed by surgical approaches using incisions placed on the skin of the face. The position of the incisions and anatomy vary depending on the region of the mandible that is approached.

What is a submental incision?

aged men with poor neck contour. The procedure is performed through a submental incision without any removal of skin and relies on. modification of deep-layer structures to improve neck contour. “Excess” skin is allowed to redistribute itself over the increased neck surface area created when.

What is Pterygomasseteric sling?

] is composed of the masseter and medial pterygoid muscles. The insertion joins the both muscles to form a common tendinous sling that allows the medial pterygoid and masseter to be powerful elevators of the jaw.

What incisions can be used during surgical intervention in submandibular triangle?

Traditional approach to the submandibular gland: lateral transcervical approach. A 4–6 centimeter incision in placed in lateral neck crease approximately 2 to 3 centimeters below the lower edge of the mandible.

Where is the submental area located?

anterior triangle of the neck
Description. The submental space is located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, under the chin in the midline. The space coincides with the anatomic region termed the submental triangle, part of the anterior triangle of the neck.

What is a neck lipectomy?

A neck lift, also known as a submental lipectomy, is a surgical procedure that removes localized fat deposits under the chin, corrects muscle laxity, tightens sagging skin or enhances a receding chin.

What is Pterygomandibular sling?

a Pterygomandibular raphe and medial pterygoid muscle tendon serve as a submucosal palpable pterygomandibular (PM) sling (arrow) with high tensile strength that extends from the pterygoid hamulus to the mandible.

What is Pterygomandibular space?

The pterygomandibular space (PM) is a space largely composed of connective tissue and muscle but also contains several neurovascular structures. It is triangular in shape and is bounded by the medial surface of the mandibular ramus laterally.

Which nerve is at risk during submandibular gland excision?

• A lower branch of the facial nerve is the nerve most likely to be bruised in the removal of a submandibular gland. If bruising occurs it affects the movement of your lower lip, leading to a slightly crooked smile.

What is submandibular gland excision?

Submandibular gland removal is surgery to take out a saliva gland below the lower jaw. The gland may have been removed because of infection, a tumour, or a blocked saliva duct. A saliva duct is a tube that carries saliva from the gland into the mouth.

What is the submental region of the neck?

The submental space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, under the chin in the midline.

Where do they cut for a Necklift?

A traditional neck lift incision often begins in the hairline at the level of the sideburn, continues down and around the ear and ends in the posterior hair. Fat may be sculpted or redistributed from the jowls and neck. The tissue underlying the neck skin is repositioned, and commonly the platysma muscle is tightened.

Where are the scars after a neck lift?

Neck lift scars, in most cases, are made behind the ears and under the chin. Neck lift surgery incisions are small, and once the procedure is complete, Dr. Myint will carefully close them to optimize the healing process. Most patients find their scars are barely noticeable.

What is pterygomandibular raphe?

Medical Definition of pterygomandibular raphe : a fibrous seam that descends from the pterygoid hamulus of the medial pterygoid plate to the mylohyoid line of the mandible and that separates and gives rise to the superior constrictor of the pharynx and the buccinator.

What is Pterygomandibular block?

The pterygomandibular space is the area where local anesthetic solution is deposited during an inferior alveolar nerve block, a common procedure used to anesthetize the distribution of the inferior alveolar nerve.

What causes Frey’s syndrome?

The exact underlying cause of Frey syndrome is not completely understood. The most widely held theory is that Frey syndrome results from simultaneous damage to sympathetic and parasympathetic nerves in the region of the face or neck near the parotid glands.

Why is it called submental triangle?

The submental triangle defines a sub-region of the anterior cervical region (anterior triangle of the neck). It is one of four smaller triangles within the anterior triangle of the neck and contains some important vascular structures.

What are the 2 main triangles of the neck?

The triangles of the neck are the topographic areas of the neck bounded by the neck muscles. The sternocleidomastoid muscle divides the neck into the two major neck triangles; the anterior triangle and the posterior triangle of the neck, each of them containing a few subdivisions.

How are Risdon incisions made in a condylar neck fracture?

The Risdon incisions were made using the techniques mentioned above, and fixation of the left angle was performed using absorbable miniplates and screws after reduction. For the right condylar neck, the Risdon approach was used to expose the fracture site.

How is the marginal mandibular nerve identified in a Risdon approach?

Approaching the mandible from an incision below the marginal mandibular nerve is the most crucial point in the Risdon approach. The marginal mandibular nerve is identified easily without much dissection, and if a flap is elevated, including the nerve, there is no risk of facial nerve damage.

Where is the incision line on a dental Xray?

Using gentian violet, an incision line was marked 2–3 cm below the lower mandible border, between the angle and the facial notch of the mandible. The incision was normally 4–5 cm, but was extended in either direction in cases of inadequate exposure.

Is there a modified Risdon approach for the treatment of subcondylar fractures?

Introduction: No consensus has been reached yet on the surgical approach for treatment of condylar fractures. Objective: The aim of this study was to present modified Risdon approach (without facial nerve identification) in the treatment of subcondylar mandibular fractures.
