A case of non-Hodgkin lymphoma of the gingiva that was erroneously diagnosed and treated as a dental abscess is presented. Clinical examination showed a firm and ulcerated mass extending from the mandibular right first premolar region to the retromolar trigone. Resorption of the alveolar ridge was radiographically observed The treatment of retromolar trigone carcinomas is controversial. 2 Patients with early-stage lesions are usually treated with a single modality (either surgery or RT), whereas those with advanced disease are frequently treated with surgery and adjuvant RT The retromolar trigone, as the name suggests, is a paired triangular area situated posterior to the third mandibular molars on the left and right sides of the oral cavity. The base of each triangle is formed by the third mandibular molar, and the apex is in continuity with the maxillary tuberosity located posterior to the third maxillary molars
(Fig. 6b). An intra-oral approach at the retromolar trigone is appropriate for draining abscesses medial to the ramus of the mandible. For those located lateral to the mandibular ramus, an extra -oral approach along the inferior border of the mandible is necessary(!) The masticator space may be secondarily involve Infection is postulated to track posteriorly from the retromolar trigone to become sequestered as an abscess within the pharyngeal wall [ 9 ]. The pterygo-mandibular raphe may act as a watershed structure enabling simultaneous submucosal dissection into the soft palate anteriorly and extension into the parapharyngeal space posteriorly The small area behind your wisdom teeth in your lower jaw (your retromolar trigone

It has been there for over a month and wasn't too sure how long it had a been there. Hasn't grown in size but in the morning its almost like it wakes up. In the morning, I try to feel it and its not there. After a couple of minutes, it re surfaces Bulky bilateral palatine tonsils with thick-walled necrotic collection on left side, showing peripheral enhancement on post-contrast study.

Mild compression of airway is seen with surrounding fat stranding, inflammation in left parapharyngeal and retromolar trigone Pericoronitis is defined as an oral abscess of the soft tissues typically surrounding the crown of a tooth, The small triangular surface posterior to the third mandibular molar, overlying the ascending ramus, is called the retromolar trigone. Beneath the mucosa of the retromolar trigone is the pterygomandibular raphe, which is attached to.
Hi, I have a swollen retromolar trigone, that makes it difficult to open my mouth more than about an inch, and chewing is difficult. This is about the 3rd time it has happened. The other times it only really hurt when chewing. But this time there is a throbbing pain a lot of the time. and it really hurts, somtimes making my gums swell as wel retromolar trigone.

Bounded anteriorly by the last erupted molar, posteriorly by the ramus of the mandible, superiorly by the maxillary tuberosity, and inferiorly by the retromolar trigone, the retromolar space has been used for flexible fiberoptic oral intubation in patients with severe trismus in whom the reduced interincisor distance does not allow for placement of a rigid laryngoscope or a tracheal tube between the teeth [ A 1/4 inch Penrose drain was inserted into the abscess cavity. The incision was partially closed with interrupted 4-0 chromic sutures. An anchoring stitch was placed through the drain at the posterior apex of the incision. Antibiotic ointment and Telfa gauze were applied In patient 3, with a HPV-negative (HPV−) retromolar trigone carcinoma, a large intratumoral abscess was appreciable at first PET/MRI examination (Fig. 1); so that, in addition to CHT/RT, the patient underwent drainage of the purulent collection This video highlights important fascial spaces and how dental infection can spread through them to mediastinu

Blunt dissection was performed until the. The retromolar space or retromolar gap is a space at the rear of the mandible, between the back of the last molar and the anterior edge of the ascending ramus where it crosses the alveolar margin.. This gap is generally small or absent in modern humans, but it was more often present in Neanderthals, and it was common among some prehistoric Amerindians, such as Arikara and Mandan Squamous cell carcinoma is the most common head and neck malignancy. It can occur in the mandible or maxilla without a preexisting oral mucosal lesion. Often, the clinical and radiographic presentation of SCC directs the clinician to favour malignancy over other pathological conditions. However, SCC may also mimic an infectious condition and therefore can pose a diagnostic challenge even for.

For surgical localization of the buccal nerve, an incision of 3.5 cm is made upwards in the mucosa of the external oblique edge of the mandibular ramus from the horizontal part of the retromolar trigone. Once the area of fat is exposed, the buccal nerve can be identified. The buccal nerve has dimensions of between 0.91 and 1.78 mm

The final diagnosis of Verrucous carcinoma in relation to the right buccal mucosa, retromolar trigone area was considered. Surgical excision was performed for lesion. En bloc resection was done followed by Endodontic treatment for the tooth 17.

To drain the superficial compartment, make a stab incision in the mucosa lateral to verti-cal ramus of the mandible and advance a haemostat lateral to the coronoid process into the abscess
