A nurse is caring for a client with chronic otitis media who is scheduled for a mastoidectomy. Which nursing intervention should be the priority in the immediate postoperative period?

Positioning the operative ear upward prevents drainage pooling and reduces pressure on the surgical site, promoting healing. Other interventions like coughing (increases intracranial pressure), direct ice application (may cause tissue damage), or removing dressings (risk of infection) are not priorities.

Understanding the Priority Post-Mastoidectomy Intervention

The correct answer is to position the client with the operative ear facing upward. In the immediate postoperative period following a mastoidectomy, the primary nursing priority is to protect the surgical site and promote healing while preventing complications. The rationale is deeply rooted in the specific risks associated with this otologic procedure.

Why Positioning is the Priority
A mastoidectomy involves the removal of infected air cells within the mastoid bone, located directly behind the ear. The surgery creates a communication between the middle ear, the mastoid cavity, and the external environment. Positioning the operative ear upward achieves two critical goals. First, it prevents direct pressure on the surgical site, which would cause significant pain and could disrupt the delicate wound closure or dislodge a graft. Second, and more importantly, this position facilitates dependent drainage of blood and serous fluid from the wound site, using gravity to prevent the accumulation of fluid under the skin flap or within the newly created cavity. A hematoma or seroma formation can become a medium for infection and jeopardize the surgical outcome .

Analyzing the Incorrect Options

Option 2: Encourage frequent coughing and deep breathing exercises. While this is a standard postoperative intervention to prevent atelectasis and pneumonia after general anesthesia, it is not the priority for a mastoidectomy patient. Forceful coughing and the Valsalva maneuver dramatically increase intrathoracic and, consequently, intracranial pressure. This pressure spike is directly transmitted to the middle ear and the surgical site, which can dislodge delicate grafts, cause bleeding, and increase the risk of air entering the sterile cavity. The review on postoperative nausea and vomiting (PONV) highlights that in otologic surgeries, any activity that creates pressure changes can jeopardize graft stability and hearing outcomes ^[3]. Therefore, this intervention is contraindicated unless specifically modified for this patient population.

Option 3: Apply ice packs directly to the surgical site. Applying ice directly to the surgical site is contraindicated. A bulky pressure dressing is typically applied after a mastoidectomy to prevent hematoma formation. Placing an ice pack over this dressing would add unwanted pressure, potentially causing tissue ischemia and necrosis of the postauricular skin flap. Furthermore, moisture from a melting ice pack could contaminate the sterile surgical dressing, creating a conduit for pathogens to reach the fresh wound. The goal is to protect the integrity of the incision and the underlying structures, which is best achieved by leaving the initial dressing clean, dry, and undisturbed.

Option 4: Remove the ear dressing to assess drainage. The initial surgical dressing applied in the operating room is a critical component of the postoperative care plan. It provides necessary pressure to minimize edema and hematoma formation. Removing it prematurely to assess drainage disrupts this protective environment and introduces a significant risk of infection. Assessment of drainage is performed by observing the outer surface of the dressing for any strikethrough, noting the color and amount, and reinforcing the dressing if necessary. The initial dressing is typically removed only on the surgeon’s order, often 24 to 48 hours postoperatively.

Connecting to Broader Postoperative Risks
The emphasis on a stable, pressure-free surgical site is further supported by the high incidence of procedure-specific complications. Otologic surgeries, including mastoidectomy, carry a notable risk of PONV. The act of vomiting generates a powerful and sudden increase in intracranial and middle ear pressure, which is precisely the mechanism that can disrupt graft placement and compromise the surgical repair ^[3]. While a superficial cervical plexus block may be used to reduce PONV in some otologic procedures, the nurse's immediate priority remains the physical protection of the site through proper positioning . The pain trajectory following mastoidectomy is also significant, and poor positioning that places traction or pressure on the wound will exacerbate the patient’s pain, hindering recovery . By maintaining the operative ear in an upward position, the nurse directly mitigates the key threats of pressure injury, fluid accumulation, and graft displacement.
