A swinging upper eyelid approach for excision of lacrimal gland masses.

PURPOSE: To describe a novel transconjunctival technique for excision of well-defined masses of the orbital lobe of the lacrimal gland. METHODS: Case series of three patients undergoing excision of a well-defined mass of the orbital lobe of lacrimal gland using a swinging upper eyelid flap. This technique entails a supratarsal conjunctival incision combined with lateral canthotomy and superior cantholysis. RESULTS: Complete removal of the mass without visible scars was achieved in all cases. There were no complications related to this approach. CONCLUSION: The swinging upper eyelid approach produces a wide exposure of the superolateral orbit. It allows safe removal of large lacrimal gland masses without the need for bone removal, while affording acceptable cosmesis.

Combined levator and frontalis muscle advancement flaps for recurrent severe congenital ptosis.

BACKGROUND: To evaluate the outcomes of combined levator resection and frontalis muscle advancement for surgical management of recurrent severe congenital ptosis. DESIGN: Retrospective, nonrandomized interventional case series. METHODS: A retrospective review was performed of patients who underwent combined levator resection and frontalis muscle advancement for recurrent congenital ptosis between 2017 and 2020. Inclusion criteria were levator function of 4 mm or less and margin reflex distance 1 (MRD1) of 0 mm or less. Main outcome measures were postoperative MRD 1, lagophthalmos, lash angle, and grades of eyelid contour and crease. The outcomes were assessed by reviewing medical charts and photographs. RESULTS: Thirty-one patients (35 eyelids) met the inclusion criteria. The mean preoperative MRD1 was -1.14 ± 1.56 mm, which improved to 3.93 ± 0.52 mm with an average lagophthalmos of 0.91 ± 0.74 mm at the last follow-up. A total of 91.4% of eyelids had excellent eyelid contour, crease, and eyelash angle at the final follow-up. One eyelid required revision surgery. There were no other significant complications. CONCLUSIONS: For poor function recurrent congenital ptosis, combining levator resection and frontalis muscle advancement is an effective method that results in long-term correction with cosmetically pleasing outcomes and minimal complications.

Clinico-radiologic characteristics of lacrimal sac area swellings misdiagnosed as dacryocystocele or mucocele.

PURPOSE: Several non-lacrimal lesions can present with lacrimal sac area swelling mimicking a dacryocystocele or mucocele with a possibility of misdiagnosis. This study investigates the clinic-radiologic characteristics of the mimicking conditions compared to true lacrimal sac distension. DESIGN: Retrospective, comparative, interventional case series. PARTICIPANTS: Patients referred by primary care ophthalmologists between January 2015 and October 2021 with a misdiagnosis of dacryocystocele or lacrimal sac mucocele (n = 39) and an age-matched group of proven true lacrimal sac swelling (TLS group, n = 44). METHODS: Data collected included demographics, presenting features, investigations, management, histopathology, and outcomes. Both groups were statistically compared for several clinical and radiological variables. RESULTS: Final diagnoses in the mimicking group were skin/subcutaneous swellings (14/39, 35.9%), vascular malformations (10/39, 25.6%), inferomedial anterior orbital cysts (7/39, 17.9%), sino-orbital masses (5/39, 12.8%). Female gender (<0.001), epiphora (p = 0.001), and discharge (p < 0.001) were significantly more frequent in the TLS group. The mimicking group was more likely to be associated with a longer swelling duration (p < 0.001), a swelling extending beyond the lacrimal sac area (p <0.001), orbital signs (p <0.001), and periorbital abnormality. Non-patent lacrimal irrigation (p < 0.001) was significantly more frequent in the TLS group. On imaging, all swellings in the mimicking group were separate from the lacrimal pathway and 94.9% (37/39) extended beyond the lacrimal sac fossa. CONCLUSION: Various cutaneous, subcutaneous, vascular, inferomedial orbital cystic, and sinonasal pathologies can present with lacrimal sac area swelling and mimic a TLS. A high index of suspicion, a thorough clinical evaluation and proper imaging are essential to avoid a misdiagnosis.

Primary Dermis Fat Grafting for Socket Reconstruction: Retrospective Comparison of Electrocoagulation versus Scalpel Dissection for Epidermis Removal.

PURPOSE: To evaluate outcomes of the use of electrocoagulation for epidermis removal in dermis fat grafting (DFG) compared to the conventional scalpel dissection in patients who underwent primary anophthalmic socket reconstruction. DESIGN: Retrospective, observational, and comparative study. METHODS: A retrospective review was performed on patients who underwent primary DFG for socket reconstruction between 2017 and 2019 at tertiary teaching hospitals. Patients with previous orbital surgery, previous radiotherapy to the periocular region, any medical condition that affects healing, cicatrizing ocular surface disease or heavy smokers were excluded. Patients with complete documentation of preoperative and postoperative data only were included. Patients were divided into two groups; group A: epidermis removal by the traditional scalpel dissection and group B: epidermis removal using low power setting electrocoagulation. The main outcome was the timing of complete epithelialization of the dermis layer. Other outcomes included implant motility, prosthesis fitting, patient's satisfaction, and any complications. RESULTS: A total of 27 patients met the study criteria, and the mean follow-up period was 24.81 months. There were no differences between both groups regarding preoperative characteristics. The mean duration of complete epithelialization of the DFG implant was 9.15 ± 2.94 weeks in group A compared to 22.29 ± 4.43 weeks in group B (p value <0.001). Dermal ulceration was noticed in 9 patients (64.3%) in group B compared to none in group A (p value =0.001). Dermal ulceration was significantly associated with long conjunctival healing period (p value <0.001). Volume loss was more common in group B while graft hirsutism and granuloma were more evident in group A. Final prosthesis fitting was possible in all included patients. CONCLUSION: Epidermis removal using the electrocoagulation is related to much more delayed epithelialization of the dermis with a higher rate of dermal ulceration compared to the scalpel dissection technique. However, there was no significant difference between both groups regarding the final prosthesis fitting or the overall patient satisfaction.

Single-triangle versus Fox pentagon frontalis suspension for unilateral severe congenital ptosis correction.

PURPOSE: To compare the functional and cosmetic outcomes of two different frontalis sling techniques for correction of severe unilateral congenital ptosis: single triangle and Fox pentagon techniques using expanded polytetrafluoroethylene (ePTFE) suture. METHODS: This randomized controlled trial included 60 eyes of 60 patients with severe unilateral simple congenital ptosis and poor levator function (≤4 mm). Participants were randomly assigned for either single triangle or Fox pentagon frontalis suspension using ePTFE suture. Functional outcome measures were margin reflex distance (MRD1), palpebral fissure height (VFH), and lagophthalmos. Cosmetic outcome parameters (lid contour, lid crease, and height symmetry) were graded as 3 (excellent), 2 (good), or 1 (poor), with a minimum of 18 months' follow-up. RESULTS: At final follow-up, there was a significant improvement in the MRD1 and VFH in both groups, with no statistical difference (P = 0.9). Both groups showed comparative cosmetic results regarding lid height symmetry, crease, and contour. The patients in the single-triangle group showed more rapid recovery of postoperative edema and lagopthalmos with less visible forehead scarring. There were no serious ePTFE sling-related complications. CONCLUSIONS: In our study cohort, the single-triangle and Fox pentagon frontalis suspension techniques had similar outcomes with respect to MRD1 and VFH and comparable cosmetic results. However, the single-triangle technique avoids two forehead incisions and was associated with less postoperative edema, lagophthalmos, and scarring.
