Clinical Studies

Objective: In this study, the authors aimed to compare the nasal physiology and nasal cavity volume with three-dimensional computed tomography (3D-CT) 1 year after the operation with the values before the operation to investigate the possible narrowing and loss of function in the nasal cavity after septorhinoplasty (SRP) operation.

Methods: Of 415 patients who had a primary SRP operation, 28 patients who met the criteria were included in the study. Nasal cavity volumes of patients with postoperative CTs were measured three-dimensionally after a mean 13 months, and objective rhinologic measurements (rhinomanometry, acoustic rhinometry, and peak nasal inspiratory flow [PNIF]) and subjective assessment methods (Visual Analog Scale [VAS], Nasal Obstruction Symptom Evaluation [NOSE]) were performed.

Results: The mean postoperative VAS and PNIF values of the patients were significantly higher than the mean preoperative values. The mean postoperative NOSE value of the patients was significantly lower than the mean preoperative values. Although the mean MCA-1 and MCA-2 levels of the patients increased postoperatively, the increase was not significant. Although the postoperative mean values of VOL-1 and VOL-2 increased compared with the preoperative values, the increase was not significant. In the CT measurements of the patients, the nasal cavity volumes were significantly higher than the preoperative values.

Conclusion: Nasal cavity volumes in patients undergoing SRP were compared with 3D-CT for the first time in the literature, and a significant increase in nasal volume was observed in the postoperative first year. This finding suggests that the correction of intranasal problems leads to an increase in the nasal volume in SRP operations, although nasal osteotomy is performed.
