A new technique for correction of iatrogenic upper eyelid retraction by using a composite flap of the orbicularis muscle and fascia on the anterior surface of the tarsal plate

Background:Upper eyelid retraction is a challenging complication of cosmetic upper eyelid blepharoplasty.To avoid extra trauma,we developed a new technique for correcting iatrogenic upper eyelid retraction by postmigrating a compound flap of the orbicularis muscle and fascia(OFC)on the anterior surface of the tarsal plate.This method extends the aponeurosis of the levator palpebrae superioris muscle(LPS),which can achieve a good correction for post-blepharoplasty retraction.Methods:We collected data from 15 patients with mild to moderate iatrogenic upper eyelid retraction who were treated at our hospital between February 2017 and December 2019.The OFC was used to replace the missing part of the LPS,and post-migration of the LPS and fixation of the OFC to the tarsal margin were conducted.Postoperative outcome measurements included postoperative binocular symmetry,double eyelid smoothness,eyelid fullness,margin reflex distance(MRD1),degree of eyelid closure,and exposure keratitis.The patients were followed-up at seven days,one month,and six months postoperatively.Results:One patient with moderate eyelid retraction showed undercorrection 6 months postoperatively,with the upper eyelid margin located at the upper edge of the pupil.The remaining patients had the upper eyelid margin stabilized at 1.0–2.0 mm below the upper corneal margin.Other observational indicators were satisfactory,including binocular symmetry,double eyelid fluency,and eyelid fullness.During the follow-up,no exposure keratitis was identified.The MRD1 indexes after the operation were significantly different(P<0.001)from those before the procedure.Conclusions:Extension and post-migration of the LPS using the orbicularis muscle and OFC structure can effectively correct mild iatrogenic eyelid retraction after ptosis with less damage and good postoperative eyelid morphology and closure function.

Bilateral Congenital Upper Eyelid Eversion (Ectropion): A Rare Presentation Responded Well to Conservative Treatment at Temeke Regional Referral Hospital-Tanzania

Congenital eversion of the upper eyelids is a rare condition, the exact cause of which remains unknown. It is more frequently associated with Down’s syndrome and black babies. If diagnosed early and treated properly, the condition can be managed without surgery. We report a case of non syndromic congenital bilateral severe upper eyelid eversion in otherwise normal 3 days old neonate of African descent (Tanzanian), born by vaginal delivery. The case was conservatively managed by lubricants, antibiotics and eyelid patching. We report this case because from the best of our knowledge it has never been documented here at our hospital and Tanzania before.

Revisiting the upper eyelid blepharoplasty advancement flap:adaptation for the repair of full-thickness upper eyelid defects—a case series

A blepharoplasty flap has been previously reported as a useful reconstruction approach for anterior lamellar defects lying between the lash line and the eyelid crease.We herein describe a variation of the blepharoplasty flap and suggest its use as an adjunct in the reconstruction of full-thickness lateral upper eyelid defects.Technique description and retrospective interventional case series.The reconstruction technique was used by an experienced oculoplastics surgeon(ASL)in 3 adults with malignant lesions involving the lateral upper eyelid margin,resulting in a post-excision 50%full-thickness defect between November 2017 and June 2020.The posterior lamella was reconstructed using an ipsilateral free tarsal graft and an inferiorly hinged transposition periosteal flap.The anterior lamella reconstruction was then performed using a local advancement flap utilizing the principles of upper blepharoplasty and Burow’s triangle.Almost full eyelid excursion and full gentle closure were evident at 1–2 weeks follow-up in all three cases.One case later developed 1–2 mm of gentle closure lagophthalmos and was managed successfully with topical lubricants.In all patients,the final eyelid contour and symmetry were adequate,with only minimal scarring,evident already 3 to 4 months postoperative.There were no major complications or need for revisions.The technique described herein highlights the utility of the blepharoplasty flap for lateral,full-thickness upper eyelid defects.This logical variation enables the reconstruction of significant defects using only local tissue,obeying the“like with like”principle,and helps avoid the need for a bridging flap.We provide preliminary evidence of the potential of a good cosmetic outcome of upper lid appearance and contour,together with a fast recovery of appropriate eyelid function.

Co-firing of levator palpebrae and masseter muscles links the masticatory and oculomotor system in humans

Simultaneous co-firing of the levator palpebrae （LP） and pterygoid muscles were recorded in Marcus Gann Syndrome （MGS） patients in early clinical studies. ＂Release hypothesis＂ proposed an intrinsic masticatory oculo- motor neural circuit and this kind circuit, which, however, has been observed only in amphibian. On the other hand, congenital miswiring hypothesis has overwhelmed other interpretations. However, the same phenomenon visualized in MGS cases was unveiled in human subjects without any sign of congenital oculomotor disorder. To further study co-firing of the upper eyelid and jaw muscles, we applied non-invasive EMG recording of the upper eyelid and ipsilateral masseter muscle belly in nine healthy volunteers. LP activity was determined initially by looking upward and active retraction of upper eyelid with head fixed. Then, dual channel inputs from upper eyelid and masseter muscle was recorded during tooth occlusion motivated by isometric masseter muscle contraction without jaw and face moving. The EMG recorded from upper eyelid when the subjects retracted eyelid with head fixed exhibited the same pattern as that collected during tooth occlusion, but the pattern was completely different from EMG of active eye closure. This reflects tooth occlusion evoked LP activity. Then, simultaneous co-firing of the LP and masseter muscle was recorded simultaneously during tooth occlusion without jaw movement. Finally, the aforemen- tioned co-firing was recorded when the subjects conducted rhythmic occlusion and synchronous EMG from both muscles was acquired. In conclusions, humans may also have an intrinsic masticatory oculomotor circuit and release hypothesis may apply, at least, to some cases of MGS.

Presence of thyroid-associated ophthalmopathy in Hashimoto's thyroiditis

·AIM: To determine the prevalence of ophthalmopathy in Hashimoto’s patients and to make a comparison in subgroups of patients·METHODS: The study involved 110 Hashimoto’s thyroiditis patients and 50 control subjects attending to the endocrinology department of the hospital. Subgroup classification of patients was made as euthyroid,subclinic and clinic in Hashimato’s thyroiditis. All patients were evaluated by a single experienced ophthalmologist for the prevalence and characteristics of eye signs.·RESULTS:Theoverallprevalencesofeyechanges were22.7%(25 patients) in patients and 4%(2 persons) in control subjects respectively(P =0.002). In patients the most common symptom was retrobulbar eye pain with or without any eye movement. Thirteen patients had significant upper eyelid retraction(11.8%). Six patients had eye muscle dysfunction as reduced eye movements in up gaze. In control patients one person had proptosis and another had lid retraction. The clinical activity score and classification of the ophthalmopathy did not show any significant differences among subgroups.·CONCLUSION:Theeyesignsweremostlymild(22.7%)and the most common eye sign was the presence of upper eyelid retraction(11.8%). Additionally six patients had eye muscle dysfunction as reduced eye movements in up gaze. Therefore we recommend to make a routine ophthalmic examination in Hashimoto’s thyroiditis patients in order not to omit the associated ophthalmopathy.

Clinical application of autologous chyle fat transplantation in the correction of sunken upper eyelid

Aim:We investigated the clinical application of autologous chyle fat in the correction of sunken upper eyelid.Methods:From November 2020 to October 2021,89 cases of correction with autologous chyle fat to sunken upper eyelid were performed(with or without other cosmetic procedures related to the eyes).An appropriate amount of fat was extracted from the superficial layer of the patient’s thigh and processed to chyle fat.About 0.5-2.8 mL of fat was injected under the orbicularis oculi muscle(roof-retro orbicularis oculi fat)or in the area where the orbital septal fat exists from the outer orbital margin of the upper eyelid.Results:In total,59 patients were followed up for 1-11 months after surgery.No infection,necrosis,vascular embolism,upper eyelid lumpiness,fat calcification,or liquefaction occurred in all patients,while seven cases showed inadequate correction.The depression basically disappeared,the shape was relatively full,the youthfulness was greatly improved,and the satisfaction of patients was high during the follow-up period.Conclusion:The correction with autologous chyle fat to sunken upper eyelid showed little trauma,short recovery periods,and satisfactory results,and it is worthy of being popularized and applied more widely.
