Is there a structural danger when overdoing alarplasty?

There are two potential issues. First, over resection of the nasal base can create an overly pinched and surgical looking nose. Second, over narrowing of the nasal base can block airflow into the nostrils and cause nasal obstruction. To an experienced rhinoplasty surgeon, it is typically clear how much tissue needs to be removed and where. Alar base modification is particularly complex and should not be trusted to someone who dabbles in rhinoplasty surgery. The results can be disastrous in inexperienced hands.

If you look closely at the nostrils, the nostril base where it meets the cheek is the only part of the nostril that has a true curve to it. Removing too much nostril tissue here can result in removal of too much of the natural curve of the nostril, leaving you with a tethered, stuck down, triangular shape that looks unnatural. Your surgeon can best show you how far you could go with alar reduction and still look good.

Over-resection of the alae can distort the normal curvature of the alar groove.  Better to be conservative .  If alar resection is being performed to reduce the nostrils, overresection can lead to airway incompetence.  So again, best to be conservative.  Computer imaging of expected rhinoplasty results is a great tool to ensuring that surgeon and patient are on the same page.All the Best,Dr. Brian Reagan
