Evaluation and Management of Lateral Wall Insufficiency

Area of Science:

• Otolaryngology
• Plastic Surgery
• Nasal Airway Function

Background:

• Nasal airway obstruction significantly impacts quality of life.
• Accurate diagnosis of the cause is essential for effective treatment.
• Lateral wall insufficiency (LWI) is a frequent, yet often overlooked, cause of nasal obstruction.

Purpose of the Study:

• To provide an overview of lateral wall insufficiency (LWI).
• To highlight the importance of recognizing LWI in rhinoplasty.
• To discuss the evaluation and management strategies for LWI.

Main Methods:

• Review of current literature on nasal valve anatomy and function.
• Clinical assessment techniques for identifying dynamic lateral nasal wall collapse.
• Surgical principles for addressing internal and external nasal valve compromise.

Main Results:

• LWI involves dynamic collapse at the internal (zone 1) and external (zone 2) nasal valves.
• Recognition of LWI is critical for rhinoplasty outcomes.
• Specific diagnostic criteria and management options exist for LWI.

Conclusions:

• Lateral wall insufficiency is a key diagnosis in patients with nasal airway obstruction.
• Rhinoplasty surgeons must be adept at identifying and treating LWI.
• Effective management of LWI improves nasal breathing and patient satisfaction.
