Oral and Maxillofacial Surgery

Case of the Month

November, 1999


The patient is a 43 y.o.male injured by falling rocks in an underground coal mining accident. The patient was transferred, via ambulance, to Owensboro Mercy Health System from an adjacent county hospital. The patient was laying face down with a nasopharyngeal airway in place. The patient had no loss of consciousness, but had difficulty speaking and breathing when in a suspine position, secondary to having a flail maxilla and mandible.


The patient has no allergies. There are no serious illnesses and the patient takes no medications. The patient had been previously hospitalized for three separate mining accidents, resulting in blindness in his right eye, lumbar vertebrae fractures, and fracture of his left leg.

The head was normocephalic. A scalp abrasion was present at the vertex. The patient had no vision in O.D., the pupil was irregular with a diameter of 7 mm. Bilateral periorbital edema and ecchymosis was noted. Epistaxis was present. The nasal complex and nasofrontal junction were intact. Teeth #s 24 and 25 were avulsed. Class III dental fractures of teeth #s 7, 26, and 31 were present. Partial avulsion of teeth #s 2, 15, and 16 was associated with dentoalveolar fractures of the maxilla, splitting the palate and creating right and left, anterior and posterior dentoalveolar segments. The palatal lacerations communicated with the maxillary vestibular lacerations and comminuted Le Fort I fracture creating traumatic oral antral openings. The split palate ran anteriorly between teeth #s 8 and 9, resulting in an oral nasal opening. Compound, comminuted right and left mandibular body fractures had associated through and through facial lacerations. A triangular segment of the left mandibular body was avulsed. Mental nerve anesthesia was present. Laceration of the lateral border of the tongue and multiple intraoral vestibular lacerations were noted.
