摘要

Current study comparing effect of two standard pathways of lateral osteotomies (ie low to low and high low high) on internal nasal valve area narrowing and nasal airway obstruction postoperatively was carried out with aim to solve the very important question that what pathway of lateral osteotomy should be carried out in aesthetic rhinoplasty and does pathway really matter in terms of airway obstruction and internal nasal valve area narrowing. Method: Patients were randomised in two groups ie Group A and Group B. Group A low to low pathway was followed and Group B High Low High pathway was followed by. Post Operatively after 8 weeks CT NOSE and PNS was done and Nasal Obstruction Symptom Score was calculated by giving patient Questionnaire asking them about nasal obstruction postoperatively.Post operative calculation of internal nasal valve area and internal nasal valve angle was calculated and comparison was done between both groups.It was found that In Group A Right sided Mean Internal nasal valve area and Mean internal nasal valve angle was 127.2_ + 30.6 & 9.9 _ + 3.8 respectively where as Left sided Mean Internal nasal valve area and Mean internal nasal valve angle was 130.3_ + 30.9 & 10.9 _ + 2.6 respectively. In Group B,Right sided Mean Internal nasal valve area and Mean internal nasal valve angle was 129.6_ + 32.4 & 10.6_ + 3.7 respectively where as Left sided Mean Internal nasal valve area and Mean internal nasal valve angle was 129.2_ + 30.6 & 10.4 _ + 3.1 respectively Mean NOSE (Table 2) score for Group A was 39_ + 5.6 and For Group B was 37_ + 5.8 There was no statistical difference on comparing these parameters between both groups.It was concluded that whatever pathway of lateral osteotomies is followed, if it is executed in a right manner there is no additional narrowing of internal nasal valve angle and internal valve area in a purely structural aesthetic rhinoplasty. Narrowing of internal nasal valve area and internal nasal valve area is mainly because if there is over mobilisation of lateral nasal bones or there is disruption of inner perichondrium.
