“…Moina et al illustrated the anatomy and derivation of DSN. This illustration showed a muscle beginning from the caudal tip of the septum and reaching the OOM clearly [12]. Furthermore, it is shown to be the inferomedial border of the "deep pyriform space."…”

Introduction: Nasal musculature anatomy is a topic that plastic surgeons pay attention to. However, the presence and role of the myrtiformis muscle (MM) remain controversial. To elucidate these aspects, an anatomy-based study was conducted.Materials and methods: Seven midsagittally split and two total cadaver head's nasal bases, embalmed with modified Larssen solution (MLS), were dissected for MM anatomy. The features of this muscle were photographed, and a video of its function was recorded.Results: It was found that MM originates from the maxillary alveolar process and continues as two heads, one reaching the alar base with spicular fibrotendinous endings and the other extending to depressor septi nasi fibers. Owing to its bi-vectoral muscle fibers, MM is found to constrict the nares by simultaneously forcing the alar base and lowering the columella. It was also found that left-sided muscles were larger than right-sided muscles.Conclusions: The MM is found to be a constrictor muscle of the nares in this study, contrary to recent observations.

“…Some reports in the literature emphasize that the depressor septi nasi muscle should be cut during rhinoplasty to prevent the nasal tip from being pulled down, especially when laughing, and to prevent a decrease in nasolabial angle during the postoperative period [47,52]. However, these reports only took aesthetic results into consideration; moreover, RMM and EMG were not performed and the dynamic functions of the nose were not evaluated.…”

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.

“…This outcome supported the previous studies, which presented the NTDs as a major cause behind the delayed deterioration of the aesthetic outcome in patients with hyperactive NTDs. 19,20,21 These previous studies used the changes in the NTP 19,21 and the NLA 20 as an objective tool to evaluate the aesthetic outcome after closed rhinoplasty. Certainly, measuring both parameters in an animated pause would represent a more objective evaluation tool.…”

Background: During smiling, the prominent action of nasal tip depressors (NTDs) antagonizes the rhinoplasty nasal tip support maneuvers and favors scarring forces‚ pulling the nasal tip in a less projecting vector. The NTDs' disinsertion is feasible through the open rhinoplasty approach. Yet, the reliability of the open approach to manipulate all NTD attachments is still questionable. The upper buccal sulcus approach (UBSA) is a reliable approach to manipulate variable anatomy of the NTDs. Methods: Thirty-two patients had primary open rhinoplasty between 2016 and 2020. All patients showed hyperactive NTDs during smile preoperatively. Through UBSA, disruption of NTDs was done. Aesthetic outcome was evaluated by comparing the pre/postoperative nasal tip projection (NTP) and nasolabial angle (NLA) in lateral views. Results:The sample included 28 women and four men, and the mean age was 30.7 years. The mean follow-up period was 23.8 months. Preoperatively, 53% (n = 17) of patients showed normal NTP measurements; this percentage increased to 87.5% (n = 28) postoperatively. The mean NLA for the 32 patients was 91.0 degrees pre-operatively‚ which was increased to 102.5 degrees postoperatively. These aesthetic results were maintained throughout the follow-up period‚ with no significant increase in the incidence of complications. Conclusions:The combination of the UBSA with open rhinoplasty resulted in objective visualization and manipulation of the NTDs. This was proven by the maintained NTP and NLA in aesthetic optimum values throughout the follow-up period. We believe that UBSA can be safely combined with open rhinoplasty as a reliable hidden approach to manipulate hyperactive NTD cases.
