Comparison of the Distribution of Standardized Cosmesis and Health Nasal Outcomes Survey Scores Between Symptomatic and Asymptomatic Patients

Quantifying the Subjective Experience of Nasal Obstruction: A Review

Nasal obstruction is an exceedingly common problem and challenging to treat due to its multifactorial etiology. Therefore, measuring treatment outcomes of nasal obstruction can be equally complex yet vital to appropriately assessing symptom improvement or resolution. Both physiologic and anatomic assessments of the nasal airway exist in addition to validated patient-reported outcome measures (PROMs), which objectify subjective nasal obstruction and sinonasal symptoms. Correlation between objective and subjective treatment outcome measures is controversial with clinical guidelines favoring the use of PROMs for surgical treatment of nasal obstruction. In this review, the anatomic and physiologic measurements of the nasal airway and validated PROMs will be discussed, as well as the rationale for implementing PROMs into the rhinoplasty surgeon's practice.

Characterizing Olfactory Dysfunction in Patients with Unilateral Cleft Lip Nasal Deformities

Background: Unilateral cleft lip nasal deformity (uCLND) is associated with olfactory dysfunction, but the underlying etiology remains poorly understood. Objective: To investigate the etiology of uCLND-associated olfactory dysfunction using clinical, computational, and histologic assessments. Methods: Inclusion criteria: uCLND patients >16 years undergoing septorhinoplasty. Exclusion criteria: prior septoplasty or rhinoplasty, pregnancy, sinusitis. Measured outcomes: patient-reported scores, rhinomanometry, smell identification and threshold tests, computational fluid dynamics (CFD) airflow simulations, and histologic analysis of olfactory epithelium. Results: Five uCLND subjects were included: 18-23 years, three male and two female, four left-sided cleft and one right-sided cleft. All subjects reported moderate to severe nasal obstruction. Smell identification and threshold tests showed varying degrees of hyposmia. Nasal resistance was higher on the cleft side versus noncleft side measured by rhinomanometry (median 3.85 Pa-s/mL, interquartile range [IQR] = 21.96, versus 0.90 Pa-s/mL, IQR = 5.17) and CFD (median 1.04 Pa-s/mL, IQR = 0.94 vs. 0.11 Pa-s/mL, IQR = 0.12). Unilateral olfaction varied widely and was dependent on unilateral percentage olfactory airflow. Biopsies revealed intact olfactory neuroepithelium. Conclusions: uCLND-associated olfactory dysfunction appears to be primarily conductive in etiology and highly susceptible to variations in nasal anatomy.

Patient-Reported Outcomes Measures in Rhinoplasty: Need for Use and Implementation

Patient-reported outcome metrics (PROMs) are increasingly utilized to capture data about patients' quality of life. PROMs play an important role in the value-based health care movement by providing a patient-centered metric of quality. There are many barriers to the implementation of PROMs, and widespread adoption requires buy-in from numerous stakeholders including patients, clinicians, institutions, and payers. Several validated PROMs have been utilized by facial plastic surgeons to measure both functional and aesthetic outcomes among rhinoplasty patients. These PROMs can help clinicians and rhinoplasty patients participate in shared decision making (SDM), a process via which clinicians and patients arrive at treatment decisions together through a patient-centered approach. However, widespread adoption of PROMs and SDM has not yet been achieved. Further work should focus on overcoming barriers to implementation and engaging key stakeholders to increase the utilization of PROMs in rhinoplasty.
