The Role of Ultrasonography in The Diagnosis of Oral and Maxillofacial Disease

Objective: Ultrasonography, as a diagnostic tool, constitutes a non-invasive, cost-effective, readily-availableand repeatable imaging technique. Ultrasonography has been used as a means of diagnosing various medicalconditions for many years. However, in the field of maxillofacial surgery it represents a relatively new aidin the diagnosis of various diseases affecting the oral and maxillofacial regions. These include: infection,soft-tissue related diseases and vascular anomalies which can be detected using Doppler ultrasonography.This article presents four cases, in which ultrasonography was employed to confirm diagnoses and act as aguide to treatment. Methods: Four cases of soft tissue swelling and enlargement were diagnosed with theaid of ultrasonography, namely: a submasseteric abscess, a nasolabial cyst, a dermoid cyst and a left buccalspace abscess caused by a foreign body (i.e. a fish bone). Result: In the case of a submasseteric abscess,ultrasonography was used in confirming the diagnosis and therapy, while determining the maximal point ofthe abscess. In the cases of both cysts, ultrasonography highlighted well-defined cystic lesions with internalecho showing fluid accumulation, while in the buccal space abscess, an ultrasonogram confirmed the exactlocation of the fish bone. Conclusion: Ultrasonography is a quick, widely-available, relatively inexpensive,painless procedure which can be repeated as often as necessary without risk to the patient. Thus, ultrasonographyis a valuable diagnostic aid to the oral and maxillofacial surgeon in achieving early and accurate diagnosis.

Intraoral Approach Drainage of Submasseteric Abscess in a 14-Month-Old Child

Submassteric abscess is a rare head and neck abscess. It may mimic a parotid abscess due to very close anatomical relationship. We present a 14-month-old child presented with fever, poor oral intake, irritability, and left-sided cheek swelling. Contrast-enhanced computed tomography of the neck showed an abscess formation in left submasseteric space. Intraoral drainage of abscess was successfully performed under general anesthesia. Patient recovered well and was discharged on day three post operatively. Subsequent follow up at one-week post operatively showed no recollection of the abscess.International Journal of Human and Health Sciences Vol. 03 No. 02 April’19. Page: 123-125

Iatrogenic displacement of impacted mandibular third molar into the submandibular space complicated by submasseteric abscess

The accidental tooth displacement into adjacent anatomical spaces is rare but potentially serious complication of impacted third molar extraction. A few cases of accidental displacement of third molars into anatomical spaces, such as the infratemporal fossa, the pterygomandibular space, the maxillary sinus, or the lateral pharyngeal space, during surgical interventions have been reported. In this paper, a case of a mandibular third molar accidentally displaced into the submandibular space in a 24-year-old male patient is presented. Delayed presentation resulted in infection and trismus which were controlled by antibiotic therapy and the displaced tooth recovered under general anesthesia.

Mycoplasma salivarium as a Dominant Coloniser of Fanconi Anaemia Associated Oral Carcinoma

Mycoplasma salivarium belongs to the class of the smallest self-replicating Tenericutes and is predominantly found in the oral cavity of humans. In general it is considered as a non-pathogenic commensal. However, some reports point to an association with human diseases. M. salivarium was found e.g. as causative agent of a submasseteric abscess, in necrotic dental pulp, in brain abscess and clogged biliary stent. Here we describe the detection of M. salivarium on the surface of a squamous cell carcinoma of the tongue of a patient with Fanconi anaemia (FA). FA is an inherited bone marrow failure syndrome based on defective DNA-repair that increases the risk of carcinomas especially oral squamous cell carcinoma. Employing high coverage, massive parallel Roche/454-next-generation-sequencing of 16S rRNA gene amplicons we analysed the oral microbiome of this FA patient in comparison to that of an FA patient with a benign leukoplakia and five healthy individuals. The microbiota of the FA patient with leukoplakia correlated well with that of the healthy controls. A dominance of Streptococcus, Veillonella and Neisseria species was typically observed. In contrast, the microbiome of the cancer bearing FA patient was dominated by Pseudomonas aeruginosa at the healthy sites, which changed to a predominance of 98% M. salivarium on the tumour surface. Quantification of the mycoplasma load in five healthy, two tumour- and two leukoplakia-FA patients by TaqMan-PCR confirmed the prevalence of M. salivarium at the tumour sites. These new findings suggest that this mycoplasma species with its reduced coding capacity found ideal breeding grounds at the tumour sites. Interestingly, the oral cavity of all FA patients and especially samples at the tumour sites were in addition positive for Candida albicans. It remains to be elucidated in further studies whether M. salivarium can be used as a predictive biomarker for tumour development in these patients.

Submasseteric abscess: A rare head and neck abscess

The objective of the article is to highlight and make people aware of a rare abscess which is often missed or misdiagnosed. As only a few cases have been reported, the authors feel that reporting such a case would help in proper management of the disease. We are presenting a 6.5-year-old male child with 3 weeks history of right facial swelling in the parotid region, with low-grade fever and trismus. Submasseteric abscess is a rare abscess which is often misdiagnosed as a parotid abscess or parotitis. Only a few cases have been reported. The cause is mostly dental in origin. Intravenous antibiotics often fail to alleviate the symptoms as this is a closed space and needs prompt drainage. Therefore, awareness of this complication of dental infections is vital for proper diagnosis and timely management.

Tuberculous submasseteric abscess: case report

Tuberculosis is still the most fatal infectious disease worldwide.Although it can affect every organ in the body, non cervical and extralaryngeal head and neck tuberculosis is considered rare. We report a case of tuberculous submasseteric abscess:a very unusual site.

Submasseteric Abscess Caused by Mycoplasma salivarium Infection

Mycoplasma salivarium preferentially resides in the human oral cavity. Unlike other Mycoplasma species, M. salivarium has not been regarded as a pathogen, although one case of M. salivarium-caused arthritis in a patient with hypogammaglobulinemia has been reported. We describe the first case of submasseteric abscess caused by M. salivarium.

Submasseteric abscess: Report of two cases

Submasseteric abscess is a rare infection with the symptoms of cheek tenderness and marked trismus. Submasseteric abscess is located between the masseter muscle and mandibular ramus with different appearances as sepsis, infection, or tumor. Two cases of submasseteric abscess are reported along with symptoms, causes, and management techniques. Adequate drainage and antibiotic infusion are the treatment of choice. The differential diagnosis of cheek swelling and tenderness that should be considered are parotitis, parotid gland tumor, temporomasseter joint arthritis, and submasseteric abscess.

Diagnosing protracted Submasseteric Abscess: The Role of Computed tomography

Because of its anatomical location, the submasseteric abscess mimics a parotitis. This is particularly true when the usual dental source of the infection is not present. A thorough medical history and clinical examination as well as computed tomography are important tools in the differential diagnosis.

こう筋下隙に隣接した下顎枝外側部骨膜下骨髄炎の１例

There are two types of pyogenic osteomyelitis of the jaws. One is intramedullary osteomyelitis and the other is subperiosteal osteomyelitis.Subperiosteal osteomyelitis on the outer cortical bone of the mandibular ramus adjacent to the submasseteric space, usually results from pericoronitis. If a submasseteric abscess, which is formed by backward spreading of the pericoronitis, presents itself continuously, the outer cortical bone is involved and osteomyelitis results.We would like to present a case with subperiosteal osteomyelitis of the outer cortical bone of the ramus.The patient, a 43-year-old man, visited our clinic complaining of trismus and swelling of the left cheek on 17 th of March, 1985.Two months before his first visit to us, he had pain in the region of the left lower third molar, swelling of the left cheek and mouth-opening limitation.Although he received extraction of the left lower third molar tooth and administration of antibotics at a dental clinic, he did not improve.Then he visited an ENT and was advised to visit to our clinic.At the first examination by us, clinical findings revelaed diffuse swelling on the left cheek and the left molar gingiva, trismus and pus discharge. The X-rays showed bone distraction of the outer cortex of the ramus.We administered antibiotics intravanously and operated on the patient under general anesthesia. The curettage and sauserization was done intraorally. A drain was inserted and the wound was closed.After the operation, pus discharge, swelling and trismus disappeared and there has been no reccurence.Histopathological examination of the excised and curetted tissue showed formation of active or old granullation tissue and bone necrosis. Adjacent to them, there were chronic inflammatory cell infiltration, proliferation of fibrous tissue and new bone formation.Diagnosis of subperiosteal osteomyelitis adjacent to the submasseteric space was made from its clinical feature and histopathological findings. Its location and radiological findings are characteristic, so it can be said that this case is one of typical subperiosteal osteomyelitis adjacent to the submasseteric space.

Suppurative candidiasis: review of the literature and report of case

Literature on suppurative candidiasis is reviewed and the diagnosis of the condition and the treatment of a 22-year-old man with such an infection are described. A submasseteric abscess and associated osteomyelitis of the mandibular ramus failed to respond to conventional treatment. Results of repeated cultures showed the causative organism to be Candida albicans . Treatment consisted of surgical drainage, irrigation, and use of a new antifungal drug.

Subperiosteal osteomyelitis of the mandible: A clinical survey and experimental study

The purpose of this article is to draw attention to the condition of subperiosteal osteomyelitis and to compare and contrast this process with the more familiar classic form of bone disease known as intramedullary osteomyelitis. A review of the literature indicates that in the past there has been some confusion in terminology. Subperiosteal pyogenic osteomyelitis has assumed more importance in recent years, since it is not uncommon in Great Britain and often gives rise to difficulty in diagnosis and delay in treatment. The onset is insidious, and, as a rule, the infection is comparatively mild and does not produce a general reaction. The characteristic clinical features of the inflammatory disturbance are illustrated by examples which are typical of the whole group and include antibiotic-modified infections. The pathologic mechanism is discussed, and a reason (that is, vascular anatomy) is advanced to explain the propensity for bony changes to take place following submasseteric abscess formations. Methods of treatment are considered. During the early course of the infection antimicrobial therapy and pus drainage together will cure the localized bone abscess, but some lesions may be effectively treated by systemic antibiotics alone. In the later stages of the disease removal of sequestra and infected granulation tissue may be necessary, and, to avoid recurrence, it is essential to make a planned incision and excise sufficient cortical plate to expose the whole of the lesion. Primary suturing of the wound is advocated. An experiment has been undertaken to verify that the bony changes of subperiosteal osteomyelitis can be reproduced in the animal. A nonirritant material, polytetrafluoroethylene (P.T.F.E.), was introduced between the mandibular bone and the periosteum of a sheep to simulate the theoretical mechanism of subperiosteal osteomyelitis production in man. Subsequent surgical exploration revealed reactive new bone formation, devitalization of cortical plate, and minute sequestration at the site of the implant.

Anaplastic carcinoma of a parotid gland

Summary A case of anaplastic carcinoma of the parotid gland is presented, which was originally diagnosed as submasseteric abscess.

The surgical problem of submasseteric abscess

Perusal of the dental literature has revealed scant reference to the subject of submasseteric abscess and its limitary effect in the spread of dental infection. It is apparent that the astute surgical axiom—‘pus needs drainage’—continues to be defied and reliance placed upon therapeutic measures alone, regardless of the state of infection. From such errors of judgement may arise a refractory case or change in the formal nature of the presentation. Confirmatory evidence of this tendency is shown in the radiographs of bone destruction which occurred beneath mature submasseteric pus formations. A discussion on the controversial matter of the regional anatomy was thought to be apposite, and it does seem that differences in interpretation may be due to inherent difficulties in dissection. Time alone will provide the full answer to the enigma; does an anatomical submasseteric space exist; is it an artefact; or is the pus disposal merely sub-periosteal? One thing cannot be controverted—that is, the reality of the surgical condition.

Submasseteric abscess

The role that the fascial spaces play in facial infection has been discussed. The anatomy of fascial spaces of the face and the presence and boundaries of the submasseteric compartment have been outlined. The origin of infection in the submasseteric space and the sequence of events secondary to their infection have been discussed. The relationship of this submasseteric space to the parotid gland has been considered. The differential diagnosis involved in separating an infection of this space from an acute parotitis has been reviewed. Emphasis has been placed on the never previously discussed sialographic findings associated with a submasseteric abscess. Definitive sialographic findings disclosed the presence of a laterally displaced Stensen's duct and secondary infections involvement of the accessory parotid gland. Treatment should be aimed at early incision and drainage.
