Inferior Alveolar Nerve Neurrorhaphy after Cyst Enucleation - A Case Report
Patients that experience inferior alveolar nerve injuries often complain of sensory disturbances that affect their everyday lives because of functional incompetence. Cystic lesions of the mandible may cause impingement of the sensory nerves due to many associated factors, which can complicate the surgical outcome. Here is a case report of a patient, diagnosed with a residual cyst in the anterior mandible with erosion of mental foramen, had undergone enucleation followed by conventional inferior alveolar nerve neurrorhaphy.
Surgical Approach to Dentigerous Cyst with Protection of the Inferior Alveolar Nerve
Balkan Journal of Dental Medicine, 2016
SummaryAim: To stress the importance of surgical planning when treating large dentigerous cysts.Case Report: In a routine radiographic examination, a dentigerous cyst was revealed in a 20 years old male. A surgical approach that ensured the integrity of the inferior alveolar nerve (IAN) was applied. The incision was exceeded to the mesial surface of the first molar in order to create adequate surgical field and visibility. The final result was that the exposed nerve was protected successfully.Conclusion: This case shows the necessity of a meticulous preparation, even in routine operations.
Unusual Behavior of the Mandibular Canal Associated to a Dentigerous Cyst
Journal of Dental Health, Oral Disorders & Therapy, 2015
A dentigerous cyst is an epithelial-lined developmental odontogenic cavity that encloses the crown of an unerupted tooth at the cemento-enamel junction (CEJ). Dentigerous cysts are the second most common odontogenic cysts after radicular cysts, accounting for approximately 24% of all true cysts in the jaws. 1-3 They are usually solitary in occurrence. The condition is frequently seen with the permanent dentition, usually associated with impacted mandibular third molars and maxillary canines. Pain, swelling, and facial asymmetry are occasionally seen; however, they are usually asymptomatic and observed during radiographic examination. 4 This report describes a rare case of a dentigerous cyst associated with an impacted mandibular left 3rd molar with an ectopic position of the inferior alveolar canal (IAC).
Decompression and enucleation of a large dentigerous cyst in the mandible angle – a case report
2021
Introduction: Dentigerous cyst is the most prevalent lesion of odontogenic origin, commonly radiographically diagnosed, between the second and fourth decades of life, with a predilection for the male sex. The treatment of choice is enucleation; however, decompression is indicated for cysts that reach large proportions. The most frequent complications are expansion and resorption of the bone cortex, facial asymmetry, root resorption of adjacent teeth, migration or delay of dental eruption and compression of the lower alveolar nerve canal. Objective: To report a clinical case of a dentigerous cyst adjacent to an impacted mandibular third molar, treated with decompression and enucleation. Case report: A 39-year-old male, attended the Stomatology service with a history of a radiographic finding in the mandible. At the radiopraghic evaluation, it was possible to observe a radiolucent unilocular cystic tumor lesion, well delimited by a radiopaque, asymptomatic, intraosseous image in the r...

Nasolabial cyst is quite a rare non-odontogenic, soft-tissue cyst forming in the sublabial area and the anterior maxillary region. The patients present to us with a slowly enlarging swelling, usually without any symptoms. They are commonly diagnosed earlier because of cosmetic concerns. Many a time, they are excised either under general or local anesthesia. Surgery is also feasible with nerve blocks. Infra orbital nerve is the terminal branch of the maxillary division of trigeminal nerve. Usually the block of this nerve is not commonly used as a sole anesthetic technique even in specific facial surgeries. We report a successful management of a case of excision of nasolabial cyst in an adult male under intra oral approach of infra orbital nerve block alone

lesion between the left mandibular ramus and pterygoid muscle, and part of the mass extended to the nasopharynx. A well-demarcated mandibular deformity was also found. Magnetic resonance imaging is the best tool to detect the extent of tumor and correlates well with the operative findings. 19 Diagnosis is confirmed by immunohistochemistry showing the presence of Antoni A cells, S100 protein positivity, and a palisading arrangement of spindle cells. We determined that this tumor might have originated from the inferior alveolar nerve because of paresthesia of the inferior alveolar nerve postoperatively. Surgical excision is the optimal treatment for schwannomas. 20,21 Kang et al 5 reported that more than half of surgically treated patients exhibited postoperative neural deficits that were primarily caused by iatrogenic injury to either the nerve of origin or adjacent neural ending. In our patient, transient hypoesthesia was reported postoperatively. The malignant potential of extracranial schwannomas and the risk of recurrence after surgical resection are unclear. At the 1-year follow-up of our patient, no evidence of recurrence was noted. CONCLUSIONS Schwannomas in the pterygomandibular space, especially with cystic changes, are an extremely rare form of extracranial neurogenic tumors. Our experience with this patient suggests a good prognosis for unusual patients of schwannomas with cystic changes in the pterygomandibular space treated by surgical excision, with transient neural deficits postoperatively. At 12 months of follow-up, the patient was asymptomatic with an increased maximum mouth opening and no evidence of recurrence.

Purpose: This study reviewed the common conditions associated with displacement of inferior alveolar nerve canal. Materials and Methods: General search engines and specialized databases including Google Scholar, Pub Med, Pub Med Central, Science Direct, and Scopus were used to find relevant studies by using keywords such as "mandibular canal", "alveolar canal", "inferior alveolar nerve canal", "inferior dental canal", "inferior mandibular canal" and "displacement". results: About 120 articles were found, of which approximately 70 were broadly relevant to the topic. We ultimately included 37 articles that were closely related to the topic of interest. When the data were compiled, the following 8 lesions were found to have a relationship with displacement of mandibular canal: radicular/residual cysts, dentigerous cyst, odontogenic keratocyst, aneurysmal bone cyst, ameloblastoma, central giant cell granuloma, fibrous dysplasis, and cementossifying fibroma. Conclusion: When clinicians encounter a lesion associated with displaced mandibular canal, they should first consider these entities in the differential diagnosis. This review would help dentists make more accurate diagnoses and develop better treatment plans according to patients' radiographs. (Imaging Sci Dent 2019; 49: 79-86
Large erupting complex odontoma in a dentigerous cyst removed by a piecemeal resection
Pediatric dentistry
Odontomos (ODs) ore the most frequent odontogenic tumors in Western societies; they are often asymptomatic and discovered during rautine radiography. The purpose of this report was to describe the cose of a 7O-year-oidchiid with an odontoma within a dentigeraus cyst (DC). The patient presented with a 7-week history of painfui sweiiing invoiving the right mandibie and cheek. An intraorai examination reveaied a defect of the oroi mucosa behind the permanent mandibuiar first moiar, which resembied an exposed aiveoiar bone or tooth remnants. Clinicoi and radiographic evaiuation reveaied a iarge erupting OD associated with a dentigerous cyst. The OD was separated into pieces and enucieated together with the dentigerous cyst to preserve the mandibie's integrity and becouse of the patient's age. This is the first report of an erupting OD associated with a DC in a chiid. Surgicoi removai might be a chaiienge when iarge ODs are encountered. (Pediatr Dent 2070;32:255-9)
