Modified Levator Muscle Resection Using Putterman Muller's Muscle-Conjunctival Resection-Ptosis Clamp

Abstract

Background

The traditional technique for levator muscle resection includes a time-consuming dissection procedure that causes tissue trauma and swelling. The Putterman ptosis clamp has been popularly used in recent years for conjunctival müllerectomy. In this paper, we describe a modified surgical technique for ptosis treatment using the Putterman ptosis clamp. The modified technique improves the surgical results of levator muscle resection.

Objectives

We performed a retrospective case-series study to determine the outcomes and complications associated with the use of the Putterman ptosis clamp in levator muscle resection.

Methods

Adults aged ≥18 years with moderate-to-severe ptosis underwent the modified technique for levator muscle resection. We first performed dissection to expose the aponeurosis and tarsus. Then, we placed the Putterman ptosis clamp to measure redundant aponeurotic and septal tissues and to perform the resection. Following the adjustment of the eyelid fissure, we refixed the levator muscle to the tarsus with 4-0 vicryl stitches.

Results

Seventeen patients (34 eyes) were included in the study. Of the 34 eyes, 31 (91.2%) experienced the complete resolution of ptosis after the surgery. One patient (2 eyes, 5.9%) had mild bilateral dermatochalasis and received revision surgery 6 months postoperative. One patient (1 eye, 2.9%) lost the crease of the left eye and received revision surgeries 2 and 6 months after the first surgery. No residual ptosis or severe adverse events were noted in the patients.

Conclusions

Modified levator muscle resection using the Putterman ptosis clamp is an effective procedure for ptosis treatment.
