We used pipe models to investigate the effects of paranasal sinus ostium size and paranasal sinus volume on the area-distance curves derived by acoustic rhinometry (AR). Each model had a Helmholtz resonator or a short neck as a side branch that simulated the paranasal sinus and sinus ostium. The AR-derived cross-sectional areas posterior to the ostium were significantly overestimated. Sinus vol...

OBJECTIVE To investigate effects of the nose dilating devices on nasal anatomy and breathing in healthy subjects. MATERIALS AND METHODS 27 healthy subjects were tested when using the Breathe Right nasal strip or the Nozovent dilator. Posterior rhinomanometry, acoustic rhinometry, and a subjective evaluation were used as methods. RESULTS Both devices significantly increased the minimum cross...

OBJECTIVES/HYPOTHESIS Patients with empty nose syndrome experience considerable discomfort in their daily lives and treatment is difficult for their physicians. The purpose of this study was to evaluate the outcome of an empty nose syndrome treatment via reconstruction of the inferior turbinate with porous polyethylene (Medpor). DESIGN AND METHOD A prospective self-controlled study was conduc...

Septal deviation constitutes an important component of both esthetic deformity and airway compromise in patients with cleft lip and palate (CLP). The posterior parts of the nasal septum presented greater deviation than the anterior parts in patients with complete unilateral CLP. Le Fort I down-fracture provides better access to the nasal septum than intranasal incision during rhinoplasty, espec...
