“…The inferior belly of omohyoid is used as a guide for ultrasonographic blockade of the suprascapular nerve [ 18 ], but there are concerns about potential damage to the omohyoid during catheterization of the internal jugular vein [ 19 ]. In plastic surgery, it has been successfully used as a functional flap [ 20 ]. The inferior belly of omohyoid contracts during resisted contraction at 90 degrees abduction [ 21 ].…”

Background: Palpation, a traditional haptic ability, is used daily by practitioners of all medical and surgical specialties to assess patients. In the current study, one of the authors, in a routine clinical setting, was able to deduce the dynamic features of the putative inferior belly of omohyoid. This led to a proof-of-concept study that yielded results consistent with the clinical findings. Methods: The first part of the study involved a survey of 300 rheumatic disease patients in whom the greater supraclavicular fossa was explored by palpation. While the patient kept the head straight, the clinician placed his middle three fingers 2.5–3 cm dorsal to the clavicle in the window between the sternocleidomastoid and trapezius clavicular insertions, explored the supraclavicular fossa, and palpated the paired contractile inferior belly of the assumed omohyoid during flexion in the three orthogonal planes. In the second part of the study, five normal subjects were examined in a similar manner by the same clinician and had independent ultrasonography performed on the dominant side. Descriptive statistics were used, and Yates’ corrected chi-squared test was applied to certain nominal variables. Additionally, a comparative anterolateral bilateral neck dissection was performed in a cadaveric specimen. Results: Both studies showed that the contractile structure was the inferior belly of omohyoid and that its contraction occurred during anterior neck flexion and was opposite to the side of neck rotation, resembling the sternocleidomastoid. Conclusions: Palpation uncovered a previously unknown function of the inferior belly of omohyoid, suggesting that physical examination of the musculoskeletal system based on palpation may lead to hypotheses worthy of exploration.

Objective: To study the clinical effect of conjoint fascial sheath (CFS) suspension and levator palpebrae superioris muscle shortening in the treatment of severe blepharoptosis. Methods: Forty-five patients with severe blepharoptosis (75 eyes) from May 2020 to February 2022 in the authors' hospital were divided into 2 groups: group A (n = 33, 43 eyes) and group B (n = 24, 32 eyes). Group A was operated on by CFS + levator muscle shortening, and group B was operated on by frontal muscle flap suspension + levator muscle shortening. Both groups were followed up for 12 months (until February 2023). The clinical effect was counted in 6 months after operation, the early complications were counted in 1 month after operation, and the late complications were counted in 1 month to 12 months after operation. Margin to corneal reflex distance 1 (MRD1) and palpebral fissure height (PFH) were recorded before, 1 week, 3 months, and 12 months postoperatively, and the amount of eyelid retrogression was counted again. Results: The good correction rate was 90.70% in group A, higher than in group B (71.88%), and the difference was statistically significant (P< 0.05); the early postoperative complication rate was 9.30%, lower than in group B (24.38%), and the difference was statistically significant (P< 0.05); the late postoperative complication rate was 2.33%, lower than group B (18.75%), and the difference was statistically significant (P< 0.05). The MRD1 and PFH of group A were higher than those of group B (P< 0.05) at 3 months postoperatively and 12 months postoperatively; the MRD1 and PFH of group A were lower than those of group B (P< 0.05) at 3 months postoperatively and 12 months postoperatively. Repeated measurement analysis of variance showed that there were significant differences in the main effects of MRD1, PFH, eyelid retrogression, and time in group A and group B (P< 0.05), and there was interaction between intervention and time (P< 0.05). Conclusion: Conjoint fascial sheath suspension combined with levator palpebrae superioris muscle shortening can effectively improve MRD1 and PFH, and the amount of upper eyelid retraction is controllable 1 year after operation.
