BDS Oral and Maxillofacial Surgery flashcards — 51 questions with answers

Define Oral and Maxillofacial Surgery (OMFS).
The surgical specialty concerned with the diagnosis and surgical/adjunctive treatment of diseases, injuries, and defects of the hard and soft tissues of the oral (mouth) and maxillofacial (jaws and face) region.
Which two professional disciplines does OMFS bridge, giving it its dual-degree tradition?
Dentistry and Medicine — practitioners often hold qualifications in both, reflecting the specialty's roots in dental surgery and general surgery.
Who is often regarded as a pioneering figure in the development of modern OMFS during World War I, and why?
Sir Harold Gillies — his facial reconstruction work on wounded soldiers laid the foundations of modern plastic and maxillofacial reconstructive surgery.
Name three core areas that fall within the scope of OMFS practice.
Dentoalveolar surgery (e.g., extractions and impactions), maxillofacial trauma management, and corrective jaw (orthognathic) surgery; also pathology, TMJ surgery, implants, and reconstruction.
List the bones that make up the craniofacial skeleton's facial (viscerocranium) portion.
Maxilla, mandible, zygomatic (2), nasal (2), lacrimal (2), palatine (2), inferior nasal conchae (2), vomer — the 14 facial bones.
Which bone is the only mobile bone of the facial skeleton?
The mandible, articulating with the temporal bone at the temporomandibular joints (TMJs).
What are the three buttresses (vertical pillars) of the midface that resist masticatory forces?
The nasomaxillary (medial), zygomaticomaxillary (lateral), and pterygomaxillary (posterior) buttresses.
Name the four muscles of mastication.
Masseter, temporalis, medial pterygoid, and lateral pterygoid.
Which muscle of mastication is the primary protruder of the mandible and initiates mouth opening?
The lateral pterygoid (its inferior head); acting bilaterally it protrudes the mandible and depresses the chin.
By which nerve are all four muscles of mastication innervated?
The mandibular division (V3) of the trigeminal nerve (motor root).
Provide a comparison: which masticatory muscles elevate the mandible versus which one depresses it?
Elevators: masseter, temporalis, medial pterygoid (and superior head of lateral pterygoid). Depressor/protruder: inferior head of lateral pterygoid (with suprahyoids).
Which cranial nerve provides general sensory supply to the face, and what are its three divisions?
The trigeminal nerve (CN V): ophthalmic ($V_1$), maxillary ($V_2$), and mandibular ($V_3$).
Which nerve provides sensation to the mandibular teeth, and through which canal does it run?
The inferior alveolar nerve (a branch of $V_3$), running through the mandibular (inferior alveolar) canal, exiting at the mental foramen.
Which cranial nerve supplies the muscles of facial expression?
The facial nerve (CN VII).
What is the main arterial supply to the maxillofacial region, and from which vessel does it arise?
The maxillary artery, the larger terminal branch of the external carotid artery.
Which artery supplies the lower lip and chin region and is a common landmark for facial artery ligation control?
The facial artery, a branch of the external carotid, crossing the mandible at the anterior border of the masseter.
Which branch of the maxillary artery is most frequently implicated in significant intraoperative bleeding during pterygoid region surgery?
The maxillary artery itself and its branches (e.g., inferior alveolar and sphenopalatine arteries); the sphenopalatine artery is a key source in posterior nasal/pterygopalatine bleeding.
In clinical examination of a maxillofacial patient, what does the mnemonic 'look, feel, move' encompass?
Inspection (asymmetry, swelling, lacerations), palpation (bony steps, crepitus, tenderness), and assessment of function (mouth opening, occlusion, nerve function).
What sign, checked during trauma examination, indicates a possible mid-face (Le Fort) fracture?
Mobility of the maxilla/mid-face on grasping the upper alveolus (a 'floating' maxilla), often with malocclusion and an anterior open bite.
What is trismus, and why is it clinically important in OMFS examination?
Restricted mouth opening (reduced interincisal distance, typically less than about 35 mm); it may indicate infection, muscle spasm, TMJ pathology, or condylar fracture.

Which imaging modality is the standard 3D tool for assessing facial fractures and complex bony anatomy?
Computed tomography (CT), especially cone-beam CT (CBCT) for dentoalveolar detail and multi-slice CT for extensive facial trauma.
What is an orthopantomogram (OPG/panoramic radiograph) used for in OMFS?
A single film showing both jaws, all teeth, TMJs and maxillary sinuses — used for impactions, mandibular fractures, cysts/tumours, and general dental assessment.
Name a special radiographic view used specifically to assess suspected zygomatic (malar) fractures.
The occipitomental (OM) views — 15° and 30° — which display the zygomatic arches, orbital rims, and maxillary sinuses.
What are the key components documented in a maxillofacial treatment plan?
Diagnosis, treatment aims, surgical vs non-surgical options, sequencing (emergency/immediate/definitive), risks/consent, anaesthesia choice, and post-operative/follow-up plan.
State the classic surgical priority sequence for a multiply-injured maxillofacial trauma patient.
Follow ATLS: Airway (with cervical-spine control), Breathing, Circulation, Disability, Exposure — life-threatening problems and airway/haemorrhage take precedence over definitive facial repair.
List Halsted's principles of surgical technique.
Gentle tissue handling, meticulous haemostasis, preservation of blood supply, strict aseptic technique, minimal tissue tension, accurate tissue approximation, and obliteration of dead space.
What are the three phases of wound healing that guide surgical timing and care?
Inflammatory (haemostasis/inflammation, ~days 0–3), proliferative (fibroplasia/granulation/epithelialisation, ~days 3–21), and remodelling/maturation (weeks to months).
Differentiate primary, secondary, and tertiary intention wound healing.
Primary: wound edges approximated directly (sutured). Secondary: wound left open to granulate and contract. Tertiary (delayed primary): wound left open initially, then closed after a few days (e.g., contaminated wounds).
What are the two basic techniques for tooth extraction?
Intra-alveolar (forceps/elevator) extraction — 'closed' or simple; and trans-alveolar (surgical/open) extraction — raising a flap and removing bone/tooth division.
State the three principal movements used to luxate and deliver a tooth with forceps.
Apical pressure (to expand the socket and shift the centre of rotation), buccolingual/labiopalatal rocking, and rotation (for single-rounded-rooted teeth like maxillary incisors).
What are the three orders of the lever/elevator principle used in extractions?
First-order lever (fulcrum between load and effort), wheel-and-axle, and wedge principles — elevators use these to expand bone and displace the tooth.
Name three common indications for the removal of a tooth.
Gross caries/unrestorable tooth, advanced periodontal disease with mobility, and impaction/pericoronitis; also orthodontic, pre-prosthetic, or focus-of-infection reasons.
What is a dry socket (alveolar osteitis), and when does it typically present after extraction?
A painful post-extraction complication from breakdown/loss of the blood clot exposing bone, typically presenting 3–5 days after extraction, most common after lower third molar removal.
State the Le Fort classification of mid-face fractures.
Le Fort I: horizontal, above the teeth apices (floating palate). Le Fort II: pyramidal, through the nasal bones and infraorbital rims. Le Fort III: craniofacial disjunction, separating the facial skeleton from the cranial base.
What is the commonest site of mandibular fracture, and what associated fracture is often present?
The condyle/subcondylar region and the angle are common; fractures are frequently bilateral — e.g., a parasymphyseal fracture on one side with a contralateral condylar fracture (a 'guardsman's fracture' pattern with symphysis and both condyles).
What are the two main principles guiding fracture treatment in maxillofacial trauma?
Reduction (restoring anatomical alignment and occlusion) and fixation/immobilisation (holding the reduction) — achieved by open reduction and internal fixation (ORIF) with plates or closed reduction with intermaxillary fixation (IMF).
Define orthognathic surgery.
Surgery to correct dentofacial skeletal deformities by repositioning the maxilla, mandible, and/or chin to establish normal occlusion, function, and facial aesthetics — usually combined with orthodontics.
Name the standard osteotomy used to reposition the mandible in orthognathic surgery.
The bilateral sagittal split osteotomy (BSSO) of the mandibular ramus, allowing advancement or setback.
Which osteotomy is used to reposition the maxilla in orthognathic surgery?
The Le Fort I osteotomy, allowing the maxilla to be advanced, impacted, or downgrafted.
What is a genioplasty?
An osteotomy of the chin (mandibular symphysis) to reposition the chin point (advancement, setback, vertical change, or asymmetry correction) for aesthetic/functional balance.
Distinguish an autograft, allograft, and xenograft in reconstructive surgery.
Autograft: tissue from the same individual. Allograft: from another individual of the same species. Xenograft: from a different species. Autografts avoid rejection and are the gold standard.
What is a free flap (free tissue transfer) in maxillofacial reconstruction?
Tissue detached with its vascular pedicle and re-anastomosed microsurgically to recipient vessels — e.g., the fibula free flap for mandibular reconstruction.
Which free flap is considered the workhorse for mandibular reconstruction and why?
The fibula free flap — it provides a long segment of vascularised bone that can be osteotomised to contour the mandible and support dental implants, with a reliable pedicle (peroneal vessels).
Give three examples of intraoperative complications during OMFS procedures.
Haemorrhage, nerve injury (e.g., inferior alveolar or lingual nerve), fracture of the mandible or maxillary tuberosity, damage to adjacent teeth, and displacement of a tooth/root (e.g., into the maxillary sinus or submandibular space).
What intraoperative complication can occur when extracting an upper molar with roots close to the antrum?
Oroantral communication/fistula — a pathological connection between the mouth and maxillary sinus, and possible root displacement into the sinus.
List three important postoperative complications after maxillofacial surgery.
Infection, haemorrhage/haematoma, swelling and trismus, wound dehiscence, nerve paraesthesia/anaesthesia, and delayed/non-union of osteotomies or fractures.
Differentiate primary, reactionary, and secondary post-extraction haemorrhage by timing.
Primary: at the time of surgery. Reactionary: within a few hours (as vasoconstriction/anaesthetic effect wears off). Secondary: several days later, usually due to infection eroding a vessel/clot.
Outline the general management of a wound/surgical infection after OMFS.
Establish drainage (incision and drainage of any collection), remove the source, take cultures, and give appropriate antibiotics; support with analgesia, hydration, and treat any airway compromise urgently.
What is the immediate management of an oroantral communication smaller than about 2 mm versus a larger one?
Small (<2 mm): often heals spontaneously — encourage clot, avoid nose-blowing, antibiotics/decongestants. Larger (>~3–5 mm) or established fistula: surgical closure with a flap (e.g., buccal advancement or palatal rotation flap).
Classify pain as acute versus chronic and give the usual time distinction.
Acute pain has recent onset, is protective, and resolves with healing (typically <3 months). Chronic pain persists beyond expected healing (>3 months) and may lack ongoing tissue damage.
Differentiate nociceptive, neuropathic, and psychogenic pain relevant to OMFS.
Nociceptive: from actual tissue damage/inflammation (e.g., pulpitis, post-op pain). Neuropathic: from nerve injury/dysfunction (e.g., trigeminal neuralgia, post-surgical paraesthesia/dysaesthesia). Psychogenic: pain influenced predominantly by psychological factors (e.g., atypical facial pain).
