The patient's symptoms of aching pain in the upper teeth, fullness, and pulsation in the right cheek, along with the presence of pus in the right middle nasal meatus, are most suggestive of maxillary sinusitis. The maxillary sinuses are located in the cheek area, and inflammation or infection in these sinuses can cause pain and pressure in the surrounding areas. The presence of pus in the nasal meatus further supports the diagnosis of maxillary sinusitis.

The observation of the cervical mass moving when the boy sticks out his tongue and swallows suggests that the swelling is connected to the tongue and is moving along with it. This is a characteristic feature of a thyroglossal duct cyst. The thyroglossal duct is a structure that forms during embryonic development and usually disappears before birth. However, in some cases, it may persist and form a cyst. This cyst can present as a midline, fluid-filled swelling below the hyoid bone. The movement of the cyst with tongue protrusion and swallowing confirms the diagnosis of a thyroglossal duct cyst.

Bell's palsy is a condition that affects the facial nerve, which controls the muscles of the face. It often leads to weakness or paralysis of the muscles on one side of the face. Inability to close the eyelid and drooling of saliva out of the affected side of the mouth are common symptoms of Bell's palsy. This occurs due to the weakness or paralysis of the muscles responsible for closing the eyelid and controlling saliva production.

The trigeminal (V) nerve is responsible for the general sensory innervation of structures in the orbit. This nerve carries sensory information from the face, including the skin, mucous membranes, and the orbit. It has three main branches: the ophthalmic, maxillary, and mandibular nerves. The ophthalmic branch specifically innervates the orbit and provides sensory information from the eye, including pain, temperature, and touch sensations. Therefore, the trigeminal (V) nerve is the correct answer for this question.

The correct answer is "tip to submental nodes; body to deep cervical." This means that lymphatics from the tip of the tongue drain into the submental lymph nodes, while lymphatics from the body of the tongue drain into the deep cervical lymph nodes. This is the normal drainage pathway for lymphatics from the tongue.

Accidentally severing the left recurrent laryngeal nerve during the surgical removal of the thyroid gland can result in hoarseness. The recurrent laryngeal nerve innervates the muscles responsible for controlling the tension and position of the vocal folds. When this nerve is damaged, it can lead to a change in the voice quality, causing hoarseness. The other effects mentioned in the options are not directly related to the function of the recurrent laryngeal nerve.

Damage to the facial nerve will result in hyperacusis due to paralysis of the Stapedius muscle. The Stapedius muscle is responsible for dampening the sound vibrations that enter the ear, specifically by reducing the movement of the stapes bone in the middle ear. When the facial nerve is damaged and the Stapedius muscle becomes paralyzed, it is unable to perform its function of reducing sound vibrations, leading to an increased sensitivity to sound, known as hyperacusis.

Skull sutures are not visible on X-ray as they are not made of bone. They are fibrous joints between the bones of the skull and are not visible on X-ray images. Therefore, the statement that "On X-ray, skull sutures have straight dark edges" is incorrect.

The correct answer is "In the midline through the median cricothyroid ligament." This is the correct location for performing an emergency cricothyroidostomy. The median cricothyroid ligament is a strong ligament that connects the cricoid cartilage to the thyroid cartilage. By making an incision through this ligament in the midline, a surgical airway can be established quickly and effectively in emergency situations.

The bone is likely to be lodged in the piriform recess. The piriform recess is a narrow space located between the aryepiglottic fold and the thyroid cartilage. It is a common site for foreign bodies, such as fish bones, to become lodged in the throat. The symptoms described, including difficulty swallowing and pain, are consistent with an obstruction in the piriform recess.

The superior laryngeal artery accompanies the internal laryngeal nerve into the larynx.

The patient most likely tasted the eye drops due to drainage through the nasolacrimal duct to pharyngeal taste buds. The nasolacrimal duct connects the lacrimal sac to the nasal cavity, allowing tears to drain into the nose. If the eye drops are not properly absorbed or if there is excessive tear production, the drops can enter the nasolacrimal duct and reach the back of the throat, where the taste buds are located. This can lead to the sensation of tasting the drops.

The correct answer is the Superior ophthalmic vein. Infections in the danger zone of the face can spread to the cavernous sinus through the ophthalmic veins. The ophthalmic veins are located in close proximity to the upper lip and drain blood from the face, including the area of infection. The infection can then travel through the superior ophthalmic vein to reach the cavernous sinus within the cranial cavity. This can lead to severe complications due to the proximity of the cavernous sinus to important structures in the brain.

During swallowing, the muscle that exerts pull on the wall of the auditory tube, effecting equalization of pressure between nasopharynx and middle ear cavity, is the Salpingopharyngeus. This muscle helps to open and close the auditory tube, which connects the middle ear to the back of the throat. By contracting, the Salpingopharyngeus muscle helps to equalize the pressure between the nasopharynx and the middle ear cavity, preventing discomfort or damage to the ear.

The ophthalmic artery does not enter the orbit through the superior orbital fissure. The superior orbital fissure is a small opening in the skull that allows various structures to pass through and enter the orbit. The abducens nerve, oculomotor nerve, frontal nerve, and trochlear nerve all pass through the superior orbital fissure to enter the orbit. However, the ophthalmic artery enters the orbit through a different opening called the optic canal.

The genioglossus muscle is responsible for both protraction and retraction of the tongue. It is located at the base of the tongue and plays a crucial role in movements such as sticking out the tongue and pulling it back into the mouth. This muscle helps in various functions such as swallowing, speaking, and chewing.

The tensor veli palatini does not get motor supply from the Pharyngeal Plexus. The Pharyngeal Plexus is responsible for providing motor innervation to the muscles of the pharynx and soft palate. The palatoglossus, musculus uvulae, levator veli palatini, and palatopharyngeus all receive motor supply from the Pharyngeal Plexus, but the tensor veli palatini does not.

The external palatine vein is the most likely source of persistent bleeding from the tonsillar bed after a tonsillectomy. The tonsillar bed is a highly vascular area, and the external palatine vein is one of the major veins in this region. It receives blood from the tonsillar branches of the facial artery, which supply the tonsils with oxygenated blood. Therefore, if there is persistent bleeding, it is likely that the external palatine vein has been damaged or not properly cauterized during the tonsillectomy procedure.

The greater horn of the hyoid bone, stylopharyngeus muscles, and lateral glossoepiglottic folds are derivatives of the third pharyngeal arch. The third pharyngeal arch gives rise to structures that are involved in swallowing and speech production. The greater horn of the hyoid bone is a bony structure that forms part of the hyoid bone, which supports the tongue and the larynx. The stylopharyngeus muscles are responsible for elevating the pharynx during swallowing. The lateral glossoepiglottic folds are folds of tissue that help to seal off the larynx during swallowing to prevent food and liquid from entering the airway.
