Purpose
The aim of this study was to evaluate the effect of general (GA) or local-sedation (LAA-SED) anaesthesia on the results of conjunctival mullerectomy surgery in adult patients with ptosis.
Methods
The files of 60 patients who were followed and treated in Beyoglu Eye Training and Research Hospital between 2019 and 2022 were retrospectively analysed. The data obtained from the patients’ age, gender, preoperative margin reflex distance-1 (MRD-1), postoperative 3rd month MRD-1, resection amounts according to phenylephrine response, the effect of resection amounts on MRD-1 change, evaluation of the MRD-1 measurement of the operated side compared to the other eye and the symmetry of both eyes were evaluated by statistical methods. Intraoperative and postoperative complications were noted.
Results
30 (50%) of the patients were GA and 30 (50%) were LA-SED. There was no statistically significant difference in terms of gender, preoperative mean MRD-1, and the effect of phenylephrine response on mean MRD-1. Postoperative 3rd month mean MRD-1 was 2.87±0.9 in GA, 3.2±0.9 in LA-SED (p=0.172), postoperative 3rd month mean MRD-1 change rate was 1.18±0.8 in GA, 1.43±0.7 in LA-SED (p=0.249). The amount of resection was determined according to the preoperative phenylephrine test response. 10 mm resection was performed in those who responded less to phenylephrine test, 8 mm resection was performed in those who responded more, and 9 mm resection was performed in those who responded completely. No statistically significant difference was found in the mean MRD-1 and MRD-1 change rate at the 3rd postoperative month.
Conclusion
The main purpose of this study was to determine whether the contraction of muller muscle due to sympathetic discharge caused by surgical anxiety would affect the surgical results. There was no significant difference in the mean MRD-1 at the 3rd postoperative month, but the symmetry between both upper eyelids was better in GA, although not statistically significant. The study should be supported with prospective and larger case series.
