Which method is used to examine the maxillary sinus?

The method used to examine the maxillary sinus involves thumbing under the eye, which allows the clinician to assess for tenderness or swelling over the maxillary sinus area. This physical examination technique is important because the maxillary sinuses are located below the eyes, and palpating this region can help determine if there is inflammation, infection, or other pathology present. By applying pressure just beneath the eye, the clinician can elicit a pain response if the maxillary sinus is involved, which is a common symptom associated with sinusitis or other sinus-related conditions.

Other methods mentioned may provide insights regarding related structures or conditions, but they are not specifically aimed at examining the maxillary sinus itself. For example, thumbing over the forehead usually pertains to the frontal sinuses, while palpating the cheek bones may provide some assessment of surrounding anatomical areas but does not specifically target the maxillary sinus. Looking for nasal blockages is a useful practice in overall nasal assessment, but it does not directly assess the condition of the maxillary sinus. Using the correct method enhances the accuracy of the examination and helps in reaching an appropriate diagnosis.
