Background:Unilateral cleft lip and palate (UCLP) affects nasal function and appearance. There is a lack of objective measurements to evaluate these features. This study analyzes whether objective measurements on photographs correlate with nasal function and/or appearance among adults treated for UCLP.Methods:All patients with UCLP born from 1960 to 1987 treated at the Uppsala University Hospital were invited (n = 109). Participation rate was 68% (n = 74); mean follow-up was 35 years. An age-matched control group (n = 61) underwent the same tests. Nostril area, nasal tip deviation angle, and width of the nostril were measured on photographs and were compared with functional tests and with appearance as assessed by self-assessment questionnaire, professional panel, or laymen panel.Results:The photographically measured nostril area correlated with nasal volume (acoustic rhinometry) among UCLP patients, both cleft side and noncleft side, and controls (0.331, P = 0.005; 0.338, P = 0.004; and 0.420, P < 0.001, respectively). For the patients’ noncleft side and controls, the area correlated inversely with airflow resistance at inspiration (noncleft side: −0.245, P = 0.043; controls: −0.226, P = 0.013). Laymen assessment of nasal appearance correlated with width ratio of the patients (0.27, P = 0.022) and with nasal tip deviation angle and area ratio of the controls (0.26, P = 0.041, and 0.31, P = 0.015, respectively).Conclusions:Photographic measurements correlate partially with both functional tests of the nose and panel ratings of appearance. No correlation was found with self-assessment of appearance. Evaluation of photographs needs to be combined with patient-reported outcome measures to be a valuable endpoint of nasal appearance.

“…Many rhinoplastic surgical maneuvers affect the ENV. Surgical procedures employed to treat caudal septal deformities (bringing the septum into the midline via suturing, and placement of a septal batten graft) decrease ENV resistance, as do columellar struts placed to treat nasal tip ptosis, caudal septal extension grafting, caudal septal replacement grafting, and medial crura suturing to the caudal septum [35,36]. In addition, the ENV is expanded by nasal deprojection; nasal breathing is increased [37].…”

Background Musculus depressor septi nasi and its tendon, the dermocartilaginous ligament, play an important role in external nasal valve and nasal respiration. If the ligament is cut during septorhinoplasty operations, nasal functions of the nose and facial expressions are affected. Therefore, the aim of this study was to investigate the role of M. depressor septi nasi in nasal respiration at open rhinoplasty operations using rhinomanometry and electromyography. Methods The study included 29 patients who had only external nasal deformity (nasal hump deformity). All patients underwent open rhinoplasty. The dermocartilaginous ligament of the patients in the study group (DCL ? group) was repaired but not in the control group (DCLgroup). Rhinomanometry and electromyography were applied to all patients preoperatively and postoperatively. Results In the DCL-group, right and left nasal airflow values were significantly lower in post-op (562.92 cm 3 /s and 548.57 cm 3 /s), whereas right, left, and total nasal resistances were significantly lower in pre-op (0.28 Pa/ cm 3 /s, 0.22 Pa/cm 3 /s, and 0.11 Pa/cm 3 /s). Statistically significant differences were not found between rhinomanometric measurements in pre-op and post-op values of the DCL ? group. Post-op right, left and mean values of M. depressor septi nasi amplitude in the DCL ? group (2.05 mV, 2.0 mV, 2.02 mV) were significantly higher than those in the DCL-group (1.52 mV, 1.61 mV, 1.57 mV). Conclusion Repair of the dermocartilaginous ligament during open rhinoplasty operations enhances nasal respiratory functions by expanding the external nasal valve through M. depressor septi nasi and allows the nose to participate in mimic movements.
