CBCT and MRI Analysis of Stafne Bone Defect Correlated with Submandibular Glands| Chapter 9 | Medical Research and Its Applications Vol. 11

 

Stafne’s bone defect is a developmental anatomic bone defect in the lingual side of the mandible in the area of the mandibular angle that is filled with proliferation or translocation of adjacent structures such as salivary gland tissue. Radiography illustrates this defect as a unilocular radiolucent image with a well-defined border and a regular border, found below the mandibular canal that can extend from the molars to the angle.

 

The etiology is still undefined, and two hypotheses are proposed, one is the glandular related to the submandibular or sublingual glands and the second is ischemic that affects the vascularization of the mandibular lingual.

 

Usually accidentally detected on panoramic radiographs during dental treatments as a well-limited radiolucency image with a clear peripheral regular condensation border, located below the mandibular canal. The differential diagnosis could be related to a history of trauma or traumatic bone cyst, residual cyst, dentigerous cyst, odontogenic keratocyst, focal osteoporotic bone marrow defect, and Stafne bone defect.

 

The differential diagnosis includes traumatic bone cysts, odontogenic and non-odontogenic cystic lesions, non-ossifying fibroma, focal osteoporotic bone marrow defect, and other lesions.

 

On the panoramic radiograph, Stafne’s bone defect appears as a well-limited radiolucency image with a clear peripheral regular condensation border, located below the mandibular canal.

 

Cone Beam Computed Tomography reveals more details about the localization, shape and size, and relation with the mandibular canal and Magnetic Resonance Imaging identifies the nature of the inside soft tissue. In conclusion, an association of CBCT and MRI was discovered to be a favorable methodology for exploring SBD.

Intracranial Part of Facial Nerve Along with its Clinical Implications | Chapter 5 | Medical Science: Trends and Innovations Vol. 1

The facial nerve, also known as the seventh cranial nerve, is comprised of motor and sensory roots. Both these roots of the facial nerve are attached to the ponto-medullary junction. The motor root innervates muscles of facial expression and the sensory part carries secretomotor fibers to lacrimal, submandibular and lacrimal glands and taste fibers to the anterior two third of the tongue. The facial nerve passes through the posterior cranial fossa and then through the temporal bone. It emerges out of the cranium through the stylomastoid foramen and passes through the parotid gland, ultimately innervating facial muscles. The facial nerve may be injured anywhere in its course in the cranium and in the extracranial course. If a facial nerve is injured, anywhere in its course, it leads to paralysis of facial muscles along with diminished secretion from the glands innervated by this nerve. In addition, there is a loss of taste sensation in the anterior two-thirds of the tongue leading to the helm of complications. The aim of this chapter is to highlight the intracranial course and related complications of the facial nerve. For this, various databases like Google Scholar, sciELO, PubMed etc articles and anatomical books were explored, and information is consolidated and presented in this chapter.

Reporting a Rare Case of Obstructive Sialadenitis of Submandibular Gland Due to a Nail-like Fish Bone Foreign Body | Chapter 6 | Technological Innovation in Pharmaceutical Research Vol. 2

 Introduction: Foreign body-associated sialadenitis of the submandibular gland is uncommon and poorly reported in the literature. A diagnosis of a Nail-like fish bone foreign body entering the Wharton's duct and causing acute sialadenitis is presented in this study. Foreign bodies must be investigated, and all suspicious areas must be thoroughly tested to prevent potential complications and surgeries. Since foreign body penetration is usually painful, reports of a foreign body entering the salivary gland intraorally via Wharton's or Stensen's duct are uncommon. After trauma and dental care, foreign bodies in the oral and maxillofacial area are common.

Case Report: We characterise a case of obstructive sialadenitis in the submandibular gland in a 68-year-old man caused by the penetration of a fish bone. In the left submandibular area, he had swelling and spontaneous pain. The radiographic examination of the submandibular gland revealed no foreign body. Initially, we diagnosed obstructive sialadenitis in the left submandibular gland, and the study suspects that a salivary stone may be the cause of the swelling, resulting in Wharton duct compression and milking. The foreign body was a nail-like structure that measured 1.3 cm * 3 mm* 2 mm. The foreign body was discovered to be a fish bone after pathological analysis (cartilage-like organic material).
Conclusion: This case showed that careful inspection and analysis, milking, and then paying attention to the secretion of the salivary gland contribute to accurate diagnosis and appropriate treatment, reducing the expense of assessment and treatment while also reducing the patient's confusion. Finally, milking and paying attention to clarity (glassiness) and canescent of salivary gland secretion can help with proper diagnosis.
