Comparative Study between Muller Muscle Conjunctival Resection versus Conventional Ptosis Surgery in Mild to Moderate Ptosis

Abstract

Background: Ptosis is drooping of the upper eyelid. It may be minimal, moderate or severe covering the pupil entirely. Ptosis can affect one or both eyes. Ptosis can be present at birth (congenital) or develop later in life (acquired). This study aimed to compare between the effect of Muller muscle conjunctival resection operation and conventional ptosis surgery operation in mild to moderate ptosis regarding technical difficulty, lid contour, success, rate, complication. Methods: This was a prospective study for comparison between Muller muscle conjunctival resection and conventional ptosis surgery in mild to moderate ptosis patients who attend the oculoplastic clinic in the ophthalmology department at Benha University. Results: Age (years) in MMCR group ranged from 7 to 25 with mean ± SD = 14.3 ± 6.96 while in Conventional group the Age (years) ranged from 4 to 10 with mean ± SD = 7.5 ± 2.32 with statistical significant difference (p= 0.014) between the two groups. Levator muscle resection and MMCR resected among the study groups. LR (mm) in the study population ranged from 14 to 16 with mean ± SD = 14.8 ± 0.92. MMCR resected (mm) in the study population ranged from 4 to 8 with mean ± SD = 6 ± 1.63. Conclusion: Müller's muscle–conjunctival resection is effective for ptosis correction in patients with good levator muscle function good eyelid symmetry is achieved in most patients.
