Conditions

Pituitary Tumors

Brief summary

The purpose of this study is to evaluate patient nasal outcome following endo-nasal surgery. This type of surgery is conducted for pituitary and skull base tumors. There is no published data on trauma to the nose during surgery and how it impacts nasal functioning. The investigators propose to develop a survey and administer it to patients before and after surgery to learn about their perception of nasal functioning.

Detailed description

A 9-item patient survey (the ASK Nasal Inventory) focusing on the most common postoperative complaints, such as crusting, sinusitis, pain, and ease of breathing, was developed by the anterior skull base team at the Barrow Neurological Institute. Content was validated in structured patient interviews by four subject-matter experts with both endonasal and control groups. Eligible patients for the control group included patients undergoing any neurosurgical procedure requiring anesthesia that did not involve the endonasal corridor, such as spinal decompression procedures, craniotomies for trigeminal neuralgia, and shunting procedures. This survey was self-administered pre- and 3 months post-surgery.

Change in Mean Survey Response From Baseline to 90 Days Post SurgeryBaseline, 90 days post surgeryMean survey response at 90 days post surgery between the control patients and the endonasal surgery patients using the Anterior skull base nasal inventory (ASK Nasal Inventory. A 5-point Likert scale for each question on the ASK Nasal inventory measures frequency of nasal symptoms where 1=never, 2= a little of the time, 3=some of the time, 4=most of the time, 5= all of the time. Total mean Likert scores were compared in the endonasal group to the control group after surgery. Scores range from minimum of 9 to maximum of 45. The lower the score the fewer the nasal complaints.

Pearson correlation was used to determine a correlation between each patient's responses at 90 days post op and 120 days post op.

Outcome results

Primary

Change in Mean Survey Response From Baseline to 90 Days Post Surgery

Mean survey response at 90 days post surgery between the control patients and the endonasal surgery patients using the Anterior skull base nasal inventory (ASK Nasal Inventory. A 5-point Likert scale for each question on the ASK Nasal inventory measures frequency of nasal symptoms where 1=never, 2= a little of the time, 3=some of the time, 4=most of the time, 5= all of the time. Total mean Likert scores were compared in the endonasal group to the control group after surgery. Scores range from minimum of 9 to maximum of 45. The lower the score the fewer the nasal complaints.

Time frame: Baseline, 90 days post surgery

Population: Power analyses were conducted to determine a sample size large enough to significantly detect change with 90% power using a pre- post research methodology.
