🦷 BEST OF MAXFAC — DAILY TEST #002 Answers + Explanations Q1. Which nerve is commonly at risk during mandibular third molar surgery? ☑ Answer: B. Lingual nerve Explanation: The lingual nerve lies close to the lingual aspect of the mandibular third molar region and can be injured during surgical removal, causing altered sensation of the tongue and lingual gingiva. ⸻ Q2. What is a common site of odontogenic keratocyst (OKC)? ☑ Answer: B. Posterior mandible Explanation: OKC commonly occurs in the posterior mandible, especially the angle–ramus region. It can grow extensively with relatively little expansion. ⸻ Q3. Which muscle is mainly responsible for protrusion of the mandible? ☑ Answer: C. Lateral pterygoid Explanation: The lateral pterygoid is the primary muscle involved in mandibular protrusion. Bilateral contraction pulls the mandible forward. ⸻ Q4. Which imaging modality provides 3D assessment of an impacted third molar in relation to the mandibular canal? ☑ Answer: C. CBCT Explanation: CBCT provides three-dimensional visualization of the relationship between the roots of the third molar and the inferior alveolar canal, which is useful for surgical planning. ⸻ Q5. Infection from a mandibular molar with roots below the mylohyoid line is most likely to spread into which space? ☑ Answer: B. Submandibular space Explanation: When the infection perforates the lingual cortical plate below the mylohyoid line, it commonly enters the submandibular space. If it perforates above the line, the sublingual space is more likely. 📌 Quick Revision Lingual nerve → 3rd molar surgery OKC → Posterior mandible Protrusion → Lateral pterygoid 3D canal relationship → CBCT Below mylohyoid line → Submandibular space

☑ BEST OF MAXFAC — DAILY TEST #001 ANSWERS + EXPLANATIONS Q1 → B. Inferior alveolar nerve The inferior alveolar nerve provides sensory innervation to the mandibular teeth. Its terminal mental nerve supplies sensation to the lower lip and chin. ⸻ Q2 → B. Mesioangular Mesioangular impaction is commonly encountered in mandibular third molars. The crown is tilted toward the second molar. ⸻ Q3 → B. Winter’s classification Winter’s classification describes the angulation of an impacted third molar. 🧠 Remember: Winter → Angulation ⸻ Q4 → C. Impacted mandibular third molar A dentigerous cyst develops around the crown of an unerupted tooth and is commonly associated with impacted mandibular third molars. ⸻ Q5 → B. Occlusion Occlusion is an important part of the clinical assessment of mandibular fractures because alteration from the patient’s normal occlusion can indicate fracture displacement. ⸻ 🎯 How many did you get correct? 5/5 🔥 Excellent 4/5 👏 Very good 3/5 👍 Keep learning ≤2/5 📚 Time for revision Best of MaxFac From Basic to Master in OMFS

A patient presents with a unilateral mandibular condylar fracture following facial trauma. The patient has reduced mouth opening, deviation on opening, malocclusion and posterior premature contact. Question: What factors would influence your decision between ORIF and conservative/functional management? Which finding, in your opinion, carries the greatest weight in treatment planning?

MANDIBULAR TRAUMA? LOOK AT THE BITE. Before you look at the OPG or CT, there’s an important clinical clue that can tell you a lot about what is happening to the mandible. But… What does the occlusion actually tell you? 👀 Episode 07 coming soon. 🎬 Teaser is now LIVE on Instagram & Facebook.

🦷 BEST OF OMFS — EPISODE 06 WHY MANDIBULAR FRACTURES DON’T ALL DISPLACE THE SAME WAY Not every mandibular fracture behaves the same. In this episode, we look at the biomechanics behind mandibular fracture displacement — how the fracture line and muscle forces influence fragment movement. 📌 In this episode: • Favorable vs unfavorable fractures • Muscle forces acting on fragments • Body & angle fractures • Condylar fracture biomechanics • Why this matters for reduction & fixation 🎯 Don’t just identify the fracture — understand the forces behind it. Watch the episode and save it for your next trauma case. BEST OF OMFS 📲 Instagram: @best_of_maxfac

🦴 OMFS100 | DAILY OMFS PEARL #004 MANDIBULAR FRACTURE One of the first things to assess in a mandibular fracture is: OCCLUSION Why? Because alteration of the patient’s pre-injury occlusion may provide an important clinical clue to fracture displacement and treatment requirements. 🔍 Always assess: • Occlusion • Mobility of segments • Tooth injuries • Neurosensory deficit • Intraoral wounds • Extraoral swelling • Airway 🧠 TRAUMA PEARL: Never examine a mandibular fracture without checking occlusion. #OMFS100 #MandibularFracture #MaxillofacialTrauma

FASCIAL SPACE INFECTION A mandibular second or third molar infection can spread into multiple fascial spaces. The important spaces to understand: 🦠 Sublingual 🦠 Submandibular 🦠 Submental 🦠 Buccal 🦠 Masticator 🦠 Pterygomandibular 🧠 KEY CONCEPT The direction of spread depends greatly on the relationship between the tooth apex and the surrounding muscle attachments. This is why understanding anatomy → predicts infection spread. 🔥 OMFS PEARL: Don’t memorize fascial spaces alone. Know the anatomy → understand the pathway of infection. #OMFS100 #FascialSpaces #OMFS #MaxillofacialInfection

🧠 OMFS100 | DAILY OMFS PEARL #002 INFERIOR ALVEOLAR NERVE During mandibular third molar surgery, which nerve is most commonly discussed in relation to the risk of sensory nerve injury? 👉 Inferior alveolar nerve (IAN) Possible sensory disturbance includes: • Lower lip • Chin • Mandibular teeth ⚠️ IMPORTANT: The IAN is not the only nerve at risk. The lingual nerve is also vulnerable during mandibular third molar surgery. 🧠 SURGICAL PEARL: Before surgery, carefully assess the relationship between the roots of 48 and the mandibular canal on appropriate imaging. #OMFS100 #IAN #LingualNerve #ThirdMolar
