This video explains the anatomy of the nose, paranasal sinuses, and sphenopalatine ganglion and their applied anatomy (including MCQ, practical, and interactive questions). • 𝐂𝐡𝐚𝐩𝐭𝐞𝐫𝐬 (𝐭𝐢𝐦𝐞𝐬𝐭𝐚𝐦𝐩𝐬) الفصول (الطوابع الزمنية) • 00:00 - Intro (مقدمة) • 00:22 - Content (المحتوى) • 00:37 - Parts of the respiratory system • 01:19 - Nose • 01:50 - Boundaries • 4:32 - MCQ • 05:31 - Lateral wall • 08:02 - Openings in the lateral wall of the nose • 15:29 - MCQ • 16:37 - Practical question • 17:22 - Arterial supply • 20:26 - Applied anatomy (epistaxis) • 21:12 - Venous drainage • 22:01 - Nerve supply • 29:52 - Lymphatic drainage • 30:55 - Paranasal sinuses • 35:03 - Practical questions • 36:34 - Sphenopalatine ganglion • • 𝐖𝐡𝐚𝐭 𝐢𝐬 𝐭𝐡𝐞 𝐟𝐢𝐫𝐬𝐭 𝐚𝐢𝐝 𝐭𝐫𝐞𝐚𝐭𝐦𝐞𝐧𝐭 𝐟𝐨𝐫 𝐞𝐩𝐢𝐬𝐭𝐚𝐱𝐢𝐬? 🧻 • 1. Sit the person up straight and drop their head slightly forward. • 2. Apply finger and thumb pressure on the soft part of the nostrils below the bridge of the nose for at least 10 minutes. Encourage the person to breathe through their mouth while their nostrils are pinched. • 3. Cold compresses or an ice bag can be placed on the nose, as it helps blood vessels contract. • 4. A gauze moistened with epinephrine at a ratio of 1:10,000 or phenylephrine (Neo-Synephrine) may be placed in the affected nostril to help vasoconstriction and achieve hemostasis (not used in old age or history of hypertension to avoid complications). • 5. Nasal packing (done by a specialist after referral to the hospital) • 𝐖𝐡𝐚𝐭 𝐚𝐫𝐞 𝐭𝐡𝐞 𝐛𝐫𝐚𝐧𝐜𝐡𝐞𝐬 𝐨𝐟 𝐭𝐡𝐞 𝐦𝐚𝐱𝐢𝐥𝐥𝐚𝐫𝐲 𝐚𝐫𝐭𝐞𝐫𝐲 𝐢𝐧 𝐞𝐩𝐢𝐬𝐭𝐚𝐱𝐢𝐬? 🩸🩸🩸 • The external carotid artery contributes most of its supply via the maxillary (sphenopalatine greater palatine branches) and facial arteries. • The ophthalmic artery, usually a branch of the ICA, can supply the nasal fossa via the anterior and posterior ethmoidal arteries. • 𝐖𝐡𝐚𝐭 𝐚𝐫𝐭𝐞𝐫𝐲 𝐢𝐬 𝐦𝐨𝐬𝐭 𝐬𝐞𝐯𝐞𝐫𝐞 𝐢𝐧 𝐞𝐩𝐢𝐬𝐭𝐚𝐱𝐢𝐬? 🩸🩸🩸 • The sphenopalatine artery is its main blood supply; therefore, it is most often involved in idiopathic epistaxis. • 𝐌𝐂𝐐: 💪💯 • 1. A patient complains of pain during pressure on the frontal sinus. You determine that it is an infection, and you administer mucosal-shrinking medication. The mucus drains into the nasal cavity through which of the following? • A. Semilunar hiatus • B. Spheno-ethmoidal recess • C. Nasolacrimal duct • D. Sphenopalatine canal • 2. Which of the following is a part of the nasal septum? • A. Nasal part of the frontal bone • B. Cribriform plate of the ethmoid bone • C. Body of the sphenoid bone • D. Vomer • 3. Where is the drainage site of the posterior ethmoidal air sinus? • A. Superior meatus • B. Middle meatus • C. Inferior meatus • D. Sphenoethmoidal recess • 4. Where is the site of drainage of the nasolacrimal duct? • A. Superior meatus • B. Middle meatus • C. Inferior meatus • D. Sphenoethmoidal recess • 5. Where is the site of drainage of the sphenoidal air sinus? • A. Superior meatus • B. Middle meatus • C. Inferior meatus • D. Sphenoethmoidal recess • 6. Which nerve contributes as a sensory root of the sphenopalatine ganglion? • A. Ophthalmic • B. Maxillary • C. Mandibular • D. Abducent • 7. Which nerve contributes as a sympathetic root of the sphenopalatine ganglion? • A. Deep petrosal • B. Superficial petrosal • C. Greater petrosal • D. Nasopalatine • 8. Which of the following nerves contribute as a parasympathetic root of the sphenopalatine ganglion? • A. Deep petrosal nerve • B. Superficial petrosal • C. Greater petrosal • D. Nasopalatine • 9. The deep petrosal nerve arises from which of the following structures? • A. The sympathetic plexus around the internal carotid artery • B. The sympathetic plexus around the external carotid artery • C. Facial nerve • D. Glossopharyngeal nerve • 𝐂𝐨𝐦𝐩𝐥𝐞𝐭𝐞 𝐭𝐡𝐞 𝐟𝐨𝐥𝐥𝐨𝐰𝐢𝐧𝐠 𝐬𝐭𝐚𝐭𝐞𝐦𝐞𝐧𝐭𝐬: ✒️ • 1.
