Stafne bone cyst (SBC) is a bone defect usually located in the posterior portion of the mandible or mandibular angle below the inferior alveolar nerve. The cases of SBC involving multiple anterior tooth apices and penetrating the mandibular bone are extremely rare. Here we present a case of an anterior-positioned SBC mimicking periapical cyst, which penetrated the mandibular bone, with a review of the differential diagnosis.

Transoral vertical ramus osteotomy (TOVRO) procedure can result in a variety of complications. Complications commonly reported include extensive bleeding due to major blood vessel injury, unpredictable fracture, postoperative infection, neurosensory deficit related Inferior alveolar nerve, insufficient osteosynthesis, and temporomandibular joint problem. The authors describe a case of partial necrosis of the mandibular proximal segment following TOVRO, a rarely reported complication. A 37-year-old otherwise healthy woman underwent Lefort l osteotomy and TOVRO to correct mandibular prognathism. Postoperatively, she developed pain and swelling in the right submandibular region and was found to have a partial necrosis of proximal segment.

Many of the problems which are faced to the edentulous patients are related to a minimal amount of available mandibular bone volume and height. Most of the patients with mild atrophy of the mandible are treated using endosseous implant prosthodontics. TMI(Trans-mandibular Implant) can be used in case of severe mandibular atrophy, poor bone quality, atrophy of the mandible with exposed of inferior alveolar nerve, osteoporosis and the fracture of the atrophic mandible. Also it can eliminate the need for bone grafting and vestibuloplasty. The TMI is a rigid box frame structure which controls and distribute the masticatory force over the severely resorbed mandible. The box frame structure consist of a superstructure, baseplate, 4 transosseous posts, and 5 cortical screws. This is a case report that also describes about the transmandibular implant reconstruction system.

Modified surgical technique for transposition of the inferior alveolar nerve followed by immediate placement of endosseous implants in mandibles with moderate to severe atrophy are presented. Five transpositions of the inferior alveolar nerve together with the installation of 10 implants were performed in four patients. The mean postoperative follow-up time was 17 months, with a range of 8 to 20 months. All implants with functioning pontics remained stable, with no mobility or symptoms of pain and infection during the follow-up period. Neurosensory evaluation was performed using the two-point discrimination test. Two patients had objective neurosensory dysfunction at postoperative, but all the nerve function were reported as normal by the patients 4 months postoperatively.

Orbital injuries are common with facial trauma. Direct injuries to the globe are not rare but it can result in complications such as chemosis, subconjunctival hemorrhage and hyphema. Periorbital trauma or injuries to the extraocular muscles and blow-out fracture may result in lid edema, ecchymosis & ptosis and diplopia or limitation of ocular motion respectively. Indirect injuries to the optic nerve come up without any injuries but its complication is irreversible and severe such as loss of vision. The aim of this study is to review the literature on blindness or ptosis following facial trauma and present the cases of blindness after facial trauma and ptosis after mandibular fracture without specific clinical findings.

The present study reports a case of developmental salivary gland defect. On panoramic examination, large radiolucent lesion surrounded by a sclerotic wall was noted in the right posterior mandible. On CT examination, large lingual bone concavity with extra-osseous course of the inferior alveolar nerve bundle was detected. In atypical cases, it is suggested that confirmatory imaging using CT or MRI should be taken.

Trigeminocardiac reflex (TCR) is a well-known brainstem reflex that manifests as hypotension, bradycardia, dysrhythmia, and asystole when stimulation is applied to a branch of the trigeminal nerve. Most commonly associated with ophthalmic, orbital, and neurologic surgeries, mandibular division and oral cavity variants occur far less frequently. Here, we describe a case of asystolic TCR elicited by lingual nerve stimulation. This case highlights the role of specific anesthetic medications in modulating this phenomenon and reinforces the need for early recognition and clear communication in case of its occurrence. Anesthesia providers must consider discontinuing or avoiding certain medications when clinically appropriate, even during low TCR-risk procedures.

Most of the dental treatments have been routinely performed under the local anesthesia and the effectiveness has also been proved safe. However, even not frequently dentists face some complications associated with the local anesthesia. In this report, the experience of the paresthesia after mental nerve block anesthesia for an implant placement of the mandibular premolar was presented to raise awareness of the complications related with local anesthetic procedure and to discuss about the causes, the proper treatments and the preventive approach of the paresthesia.

Objectives: The goal of this study was to evaluate the rates of complications, morbidity, and safety with the transparotid approach. Materials and Methods: A retrospective study was conducted and consisted of 53 surgically treated patients in the past five years for low condylar neck and subcondylar fractures. Only patients with malocclusion and who underwent open reduction with internal fixation with the retromandibular transparotid approach were included. The examined parameters were postoperative suboptimal occlusion, deflection, saliva fistula, and facial nerve weakness. Results: Fifty-three patients had an open reduction with internal fixation on 55 sides (41 males, 77.4%; mean age, 42 years [range, 18-72 years]). Four patients (7.5%) experienced transient facial nerve weakness of the marginal mandibular branch, but none was permanent. Four patients had a salivary fistula, and 5 patients showed postoperative malocclusion, where one needed repeat surgery after one year. One patient showed long-term deflection. No other complications were observed. Conclusion: The retromandibular transparotid approach is a safe procedure for open reduction and internal fixation of low condylar neck and subcondylar fractures, and it has minimal complications.

Stellate ganglion block(SGB) is a widely used sympathetic block to diagnose or treat various painful conditions. We experienced a rare case who exhihited a contralateral Horner's syndrome following SGB. A 64-year-old female patient suffering from postherpetic neuralgia on mandibular branch of trigeminal nerve visited our pain clinic. She complained of severe burning and shooting pain on right side lower lip, ear and temporal area. We modified her previous medications and performed repeated right SGB daily, in combination with mandibular or mental and auriculotemporal nerve blocks twice a week. Her symptoms were progressively improved. A contralateral Horner's syndrome occured after the thirteenth SGB, which was performed under several attempts in the same manner and the same physician. She had no evidence of subarachnoid or brachial plexus blocks. She did not need any special treatment and returned home 2 hours later. Subsquent blocks were followed on ipsilateral Horner's syndromes.
