Nonspecific hyper-reactivity and localized allergy: cause of discrepancy between skin prick and nasal provocation test.

Objective: Disagreement between results of skin prick test (SPT) and nasal provocation tests (NPT) causes difficulty in differential diagnosis of allergic rhinitis (AR) and nonallergic rhinitis (NAR). We hypothesized this discrepancy could be due to the nonspecific hyper-reactivity (NHR) and localized allergy of the nasal cavity.

Study Design: Prospective pilot.

Pressure necrosis of septal cartilage associated with bilateral extended spreader grafts in rhinoplasty.

Objective: To investigate septal cartilage compressive changes as a result of bilateral extended spreader grafts (ESGs), which are commonly used in rhinoplasty. The buckling, rupturing, or necrosis of the recipient site leads to nasal tip structural deformity. These pathologic changes associated with bilateral ESGs warrant the clinician's attention and in-depth basic and clinical research.

Subnasale flap for correction of columella base deviation in secondary unilateral cleft lip nasal deformity.

Objective: To present the effects of subnasale (SN) flap on the correction of deviated columella base in patients with secondary unilateral cleft lip nasal (UCLN) deformity.

Patients And Methods: The patients were 6 adult Koreans with cleft cases (mean age, 29.1 y; range, 20-43 y; 1 man and 5 women; secondary UCLN deformity with columella base deviation).
