Upper airway obstruction refers to difficulty breathing through the upper respiratory tract, including the nostrils, mouth, pharynx, and larynx. This condition can be caused by factors like nasal congestion, allergies, septal deviation, and the presence of polyps in the paranasal sinuses. Nasal polyps can lead to symptoms such as persistent nasal congestion, difficulty breathing through the nose, and loss of smell. As a result, individuals may breathe through their mouths, which can lead to a low tongue position and an "adenoidal facies," characterized by an elongated face. Additionally, changes in the stomatognathic system, such as a reduced upper dental arch, malocclusions, and clockwise mandibular growth, may be observed. This study aims to explore the correlation between nasal polyps and skeletal patterns. Clinical records from 147 orthodontic patients at the Faculty of Dentistry, Mexicali, were analyzed. Information gathered included gender, skeletal class (I, II, or III), and facial biotype (dolichofacial, mesofacial, or brachyfacial). CBCT images were obtained, and various parameters, including the Jarabak index and nasal polyp presence, were analyzed. The results revealed that mesofacial biotype was the most common (40%), and skeletal Class II predominated (48%). A counterclockwise growth pattern was observed in 50% of patients, while 79% had no nasal polyps. The study concluded that no significant correlation was found between nasal polyps, skeletal class, and facial pattern. However, the absence of polyps was more common in mesofacial patients and those with skeletal Class II. The study recommends further research with larger sample sizes and standardized data collection methods to confirm these findings.
