Intraorbital Hematoma After Removal of Upper Third Molar: A Case Report

Acute retrobulbar hemorrhage after tooth extraction: Case report and treatment of a rare condition

Retrobulbar hemorrhage (RBH) refers to hemorrhage within the bony orbital cavity and most commonly results from periorbital surgery or trauma. RBH following tooth extraction is a rare occurrence. Patients with RBH will endorse symptoms of periorbital pain, double vision, or vision loss, and present with evidence of proptosis, chemosis, or subconjunctival hemorrhage. Irreversible vision loss may occur if orbital compartment syndrome (OCS) results in the setting of RBH and is not expediently treated. Herein we present a case of a 72-year-old female who developed a RBH and OCS immediately after routine molar tooth extraction. Emergent treatment by the oral surgeon with a lateral canthotomy and inferior cantholysis led to full visual recovery. Dentists and oral surgeons should be aware of this potential rare vision-threatening complication of atraumatic tooth extraction and educated on the technique of decompressive lateral canthotomy and cantholysis.

Asphyxial death related to postextraction hematoma in an elderly man

We here report an autopsy case of a man in his seventies who died from asphyxia due to compression of the trachea caused by postextraction bleeding after extraction of his left mandibular third molar by a dentist in private practice. On the morning after the tooth extraction, he had complained of dyspnea and became unconscious at home. Although he was brought to the emergency room by ambulance, he died 7 days later without regaining consciousness. Autopsy examination revealed that the lingual side of the alveolar bone was fractured at the extraction socket. Moreover, subcutaneous bleeding that extended from the extraction socket to the thyrohyoid ligament in the cervical region and deviation of the epiglottis due to the bleeding were observed. Histological findings revealed liver cirrhosis; there were no significant findings in other organs. On the basis of these findings, we concluded that alveolar bone fracture occurred during the extraction and that the bleeding spread to the cervical region. Thus, the patient had died from asphyxia resulting from airway obstruction caused by cervical subcutaneous bleeding derived from postextraction bleeding. We emphasize that tooth extraction may cause fatal complications in patients with bleeding tendencies, particularly in the elderly.

Maxillary tuberosity fracture and subconjunctival hemorrhage following extraction of maxillary third molar

Extraction of teeth is the most common minor surgical procedure performed. Complication of extraction ranges from periodontal injury to fracture of jaw in the mandible and fracture of tuberosity and oroantral communication in the maxilla. Subconjunctival hemorrhage after extraction of maxillary molar is a very rare complication, and so far, only one case is reported in the literature. We report a case of subconjunctival hemorrhage with maxillary tuberosity fracture after maxillary third molar extraction.

Subconjunctival ecchymosis after extraction of maxillary molar teeth: a case report

Extraction of teeth is usually performed by either intra-alveolar or trans alveolar methods. Subconjunctival ecchymosis occurring after intra-alveolar extraction of maxillary first and second molar teeth is a rare entity and finds no mention in the latest clinical literature. The etiology of subconjunctival ecchymosis includes traumatic and non-traumatic causes. We report a case and discuss the possible etiology and management of this complication.
