Summary
Nasal airway obstruction is common in patients with cleft lip and palate, significantly impacting breathing. Rhinomanometry objectively measures this obstruction before rhinoplasty, aiding surgical planning and patient counseling.
Area of Science:
- Craniofacial Surgery
- Otorhinolaryngology
- Medical Engineering
Background:
- Cleft lip and palate deformities frequently cause nasal airway obstruction.
- Objective assessment of nasal patency is crucial for surgical planning.
Purpose of the Study:
- To objectively assess nasal airway patency in patients with cleft deformities before secondary rhinoplasty.
- To evaluate the degree of nasal obstruction and its impact on airflow.
Main Methods:
- Active anterior rhinomanometry was used in 36 patients with unilateral or bilateral clefts.
- Nasal airflow and resistance were measured and compared to normative values.
- Degree of obstruction and lateral nasal flow ratio were evaluated.
Main Results:
- 88% of patients exhibited significant nasal airway obstruction; 12% had mild obstruction.
- Normal lateral nasal flow ratios were found in only 19% (unilateral) and 14% (bilateral) of patients.
- Mean total nasal flow was 239.9 cm³/s; mean nasal resistance was 3.55.
Conclusions:
- Rhinomanometry provides objective data on nasal obstruction in cleft patients.
- Objective functional assessment aids in defining surgical indications and managing patient expectations.
- Pre-operative rhinomanometry can enhance the functional outcomes of secondary rhinoplasty.
