1Which anatomical structure passes through the foramen ovale of the sphenoid bone?

A.Mandibular nerve (V3)

B.Maxillary nerve (V2)

C.Ophthalmic nerve (V1)

D.Middle meningeal artery

Explanation: The foramen ovale transmits the mandibular nerve (CN V3), accessory meningeal artery, lesser petrosal nerve, and emissary veins (MALE mnemonic). The maxillary nerve (V2) exits via foramen rotundum.

2During an extraoral submandibular approach (Risdon incision) to the mandibular angle, which nerve branch is at greatest risk of injury when incising the platysma muscle?

A.Marginal mandibular branch of facial nerve

B.Lingual nerve

C.Inferior alveolar nerve

D.Great auricular nerve

Explanation: The marginal mandibular branch of the facial nerve courses within or just deep to the investing layer of deep cervical fascia and the superficial layer of the submandibular fascia, roughly 1 to 2 cm below the inferior border of the mandible. It is at direct risk during submandibular incisions.

3Which fascial space infection is characterized by rapid, bilateral involvement of the submandibular, sublingual, and submental spaces with potential airway compromise?

A.Ludwig angina

B.Canine space abscess

C.Buccal space abscess

D.Temporal space infection

Explanation: Ludwig angina is a severe, rapidly spreading, bilateral cellulitis of the sublingual, submandibular, and submental spaces, typically originating from infected mandibular second or third molars. Airway compromise is the chief life-threatening hazard.

4The pterygopalatine fossa communicates directly with the infratemporal fossa laterally via which anatomical pathway?

A.Pterygomaxillary fissure

B.Sphenopalatine foramen

C.Inferior orbital fissure

D.Foramen rotundum

Explanation: The pterygomaxillary fissure connects the infratemporal fossa to the pterygopalatine fossa, transmitting the terminal part of the maxillary artery and posterior superior alveolar nerves.

5Which muscle of mastication is the primary depressor and protruder of the mandible when contracting bilaterally?

A.Lateral pterygoid muscle

B.Medial pterygoid muscle

C.Masseter muscle

D.Temporalis muscle

Explanation: The lateral pterygoid muscle (specifically the inferior head) pulls the mandibular condyle and articular disc forward along the articular eminence, producing protrusion and opening (depression) of the mandible.

6The sensory innervation to the anterior two-thirds of the tongue for general somatic sensation is mediated by which nerve?

A.Lingual nerve (V3)

B.Chorda tympani (VII)

C.Glossopharyngeal nerve (IX)

D.Hypoglossal nerve (XII)

Explanation: General somatic sensation (touch, pain, temperature) from the anterior two-thirds of the tongue is carried by the lingual nerve (branch of CN V3). Taste sensation from this region is carried by the chorda tympani (CN VII).

7In the temporomandibular joint, the articular disc is composed primarily of which histological tissue type?

A.Dense avascular fibrous connective tissue (fibrocartilage)

B.Hyaline cartilage

C.Elastic cartilage

D.Loose vascular areolar tissue

Explanation: Unlike most synovial joints which have hyaline cartilage articular surfaces, the TMJ articular surfaces and disc are composed of dense avascular fibrocartilage (collagenous fibrous connective tissue), providing greater resistance to shear and wear.

8Which artery is the principal blood supply to the temporalis muscle?

A.Deep temporal arteries (from maxillary artery)

B.Facial artery

C.Lingual artery

D.Occipital artery

Explanation: The temporalis muscle receives its primary blood supply from the anterior and posterior deep temporal arteries, which arise from the second (pterygoid) part of the maxillary artery.

9The parotid duct (Stensen duct) pierces which facial muscle before opening into the oral cavity opposite the maxillary second molar?

A.Buccinator muscle

B.Masseter muscle

C.Zygomaticus major muscle

D.Orbicularis oris muscle

Explanation: The parotid duct crosses the superficial surface of the masseter muscle, turns medially at its anterior border, pierces the buccal fat pad and buccinator muscle, and opens intraorally opposite the maxillary second molar.

10Which fascial layer forms the roof of the submandibular triangle and encloses the platysma muscle?

A.Superficial cervical fascia

B.Investing layer of deep cervical fascia

C.Pretracheal fascia

D.Prevertebral fascia

Explanation: The superficial cervical fascia (subcutaneous tissue of the neck) contains the platysma muscle, superficial veins, and cutaneous nerves. The investing layer of deep cervical fascia lies immediately beneath it.

About the Arab Board OMFS Part 1 Exam

The Arab Board Oral and Maxillofacial Surgery Part 1 written examination is taken during the early phase of OMFS residency across Arab League member countries. It evaluates candidate mastery of essential basic sciences, including maxillofacial surgical anatomy, oral pathology, bone biology, pharmacology, and perioperative surgical principles.

Assessment

A single written paper of single-best-answer multiple-choice questions focusing on the basic and applied sciences underpinning oral and maxillofacial surgery.

Time Limit

Approximately 2.5 to 3 hours

Passing Score

60%, per the ABHS examination-affairs decisions, which fix the pass mark at 60% in the primary written, final written and clinical/oral examinations of every scientific council.

Exam Fee

Set by the Arab Board of Health Specializations and national training councils across member states. (Arab Board of Health Specializations (ABHS))

Arab Board OMFS Part 1 Exam Content Outline

28%

Head, Neck, and Maxillofacial Anatomy

Cranial nerves, infratemporal and pterygopalatine fossae, fascial spaces of the head and neck, vascular supply, and TMJ functional anatomy.

24%

Oral and Maxillofacial Pathology

Odontogenic cysts and tumors, fibro-osseous lesions, salivary gland neoplasms, premalignant lesions, and bone pathologies.

18%

Surgical Physiology and Bone Biology

Bone healing, osteointegration, distraction osteogenesis, wound healing phases, calcium homeostasis, and graft physiology.

16%

Pharmacology and Anesthesia

Local anesthetics, vasoconstrictors, systemic antibiotics, analgesics, sedative agents, and emergency resuscitation pharmacology.

14%
