Filter by:Nasal obstruction is a common complaint for the patient presenting to the Otolaryngologist and/or the Facial Plastic surgeon. There are numerous potential causes of nasal obstruction, with more easily addressed pathologies such as posterior septal deviation and inferior turbinate hypertrophy often being over-diagnosed. Nasal valve obstruction, particularly dynamic nasal sidewall collapse, is of significant interest to the rhinoplasty surgeon. Traditionally, collapse of the nasal sidewall has been addressed via structural cartilage grafting, with alar batten grafting being the most commonly used method to provide support to the weak nasal sidewall. Recently, an absorbable nasal implant, comprised of a polylactic acid copolymer, has been advocated for supporting the nasal sidewall and relieving nasal obstruction. There are several proposed advantages of the implant over traditional operative techniques, namely the ease of endonasal insertion, which can be performed in the outpatient clinic setting. Preliminary investigations demonstrate subjective improvement in nasal obstruction with use of the implant, however, there has been no direct comparison with traditional techniques utilizing cartilage grafting. This study is being done at both UVa and in Oregon. This prospective study will randomize patients with nasal obstruction and documented dynamic nasal sidewall collapse into one of two groups undergoing treatment with either endonasal batten grafting or the absorbable Latera nasal valve implant. Preoperative and postoperative nasal obstruction will be assessed with a validated survey for nasal obstructive symptoms, the Nasal Obstruction Symptom Evaluation (NOSE) score. The mean preoperative and postoperative NOSE score between the groups will be compared at 1, 6, 12, and 24 months post-operatively to compare the efficacy of both techniques. Subjects will be blinded to the surgical intervention they receive.
Lateral nasal wall insufficiency is a source of nasal obstruction which plagues many people as the sidewall of the nose collapses due to negative pressure and structural weaknesses of the nose. Bone anchored suture suspension is used by many surgeons to treat it, and involves anchoring the nasal sidewall to the bony rim below the eye. Lateral crura strut graft is another well described and universally used technique involves strengthening lateral crus of lower lateral cartilage of the nose with piece of cartilage. This study aims to compare the two well known and universally used treatments to each other. Based on expert opinions these procedures are both safe and efficient but given lack of randomized clinical trials comparing these 2 techniques, it is difficult to extrapolate which procedure is superior.
