A hierarchical stepwise approach to evaluate nasal patency after virtual surgery for nasal airway obstruction

AbstractThe sensation of nasal airflow, or nasal airway patency, is an important consideration in the treatment outcome of nasal airway obstruction. Clinicians striving to optimize the nasal passageway have relied on techniques aimed at decreasing peak airway resistance across nasal valves. Nonetheless, the evaluation of the nasal airway is multifaceted, and the objective determinants of subjective nasal patency remain incompletely elucidated. While rhinomanometry, peak nasal inspiratory airflow, and acoustic rhinometry have traditionally been used in research to focus on resistance as a measure of patency, an emerging body of evidence suggests that subjective nasal patency is more significantly correlated to the dynamic change of nasal mucosal temperature. The objective of this review is to provide the technical background on nasal airflow perception and intranasal trigeminal function as crucial to those performing functional and aesthetic rhinosurgery.

Patients’ subjective assessment of nasal patency often does not correspond to the objective results of functional and imaging examinations. The objective of this study was to identify the rhinometry (AR) and rhinomanometry (RMM) parameters that were best correlated to patients’ self-evaluation of nasal patency before and after nasal airway obstruction surgery. The study material consisted of RMM and AR results as well as SNOT-20 self-evaluation questionnaires completed by 233 patients presenting with rhinological problems and routinely diagnosed at the RMM Lab of the Department and Clinic of Otolaryngology of the Medical University of Warsaw. Data were collected from 70 females (31.4%) aged 18 through 81 years and 153 males (68.6%) aged 16 through 81 years. The results were subjected to statistical analysis by a licensed statistician using the Statistica 10 software package. A statistically significant relationship was demonstrated between the subjective perception of nasal patency and RMM results. The higher the asymmetry of air flow within the left and the right nasal cavity, the higher the perceived restriction of nasal patency. Significant differences were observed between patients reporting maximum discomfort regarding impaired nasal patency and the remaining patients: the former were characterized by nasal resistance values being several-fold higher than that observed in the latter while nearly always improving after nasal airway obstruction surgeries. No significant reflection of patients’ self-evaluation of nasal patency was found in the acoustic rhinometry measurements.

Taking Care

The pathology of the deviated nose is discussed in relation to its bony and cartilaginous components. The importance of the interlocking stresses within the septal cartilage is pointed out especially with respect to continuing deformation after trauma. The methods of rhinometry are analysed and normal airflow through the nose is described. The effects on the nasal airway of a caudal dislocation of the septum, an angulation at the valve area, a high septal deflection and an excessively wide choana are discussed. In the treatment of a deviated bony segment the difficulties of medial and lateral osteotomies are described. The indications for a septoplasty are thought to be a dislocated caudal end, a tip deviation and an external lateral angulation. The submucous resection of the septum should be reserved for resolved haematoma and cartilage absorption. The importance of the patient's priorities in deciding what operation to do are pointed out. Finally the experimental work on the effect of cartilage and mucoperichondrium resection on nasal growth is reviewed. It is suggested that a child with a severe septal deflection and airway obstruction should be offered a septoplasty taking care not to damage the mucoperichondrium.
