Purpose The aims are to compare short- versus long-term patient satisfaction and report temporary versus permanent complications in 650 patients with endoscopic forehead lift procedure (EFL). Methods This is a retrospective study on all of the consecutive patients with EFL. Patients with previous trauma and surgery and less than 2 years follow up were excluded. Short- (6 months) and long-term (≥2 years) patient satisfaction (visual analog score [VAS], 0-100) were recorded. Patients' perspectives on temporary versus permanent complications were also documented. Results Mean age and follow up were 46.4 and 7.1 (2-13) years, respectively. Long-term satisfaction (79.9) was significantly lower than the short term (96.6). The long-term satisfaction decreased in 95.7%, increased in 2.7%, and remained the same in 1.6% of the patients. Intraoperative skin laceration occurred in 3 patients (0.5%). Mean time of forehead numbness recovery was 2.3 months. Temporary complications were itching (13.7%), headache (6.3%), unilateral facial nerve palsy (5.8%), acne (3.2%), and remained staples (1.7%). Permanent complications included undercorrection (7.1%), alopecia (4.2%), forehead irregularities (2.3%), surprised look (2.2%), incision site complications (2%), and glabellar depression (0.9%). Reoperation (1.2%) was performed for undercorrection and alopecia. While short-term satisfaction was significantly lower in patients with temporary facial nerve paresis, long-term satisfaction was lower in patients with undercorrection and reoperation. Conclusion A high satisfaction scores of 96.6 and 80 were observed in the short- and long-term follow up after the EFL. Frequency of temporary and permanent postoperative complications was 30.3% and 15.8%. Reoperation rate was 1.2%.

Purpose To describe the frequency of blepharoptosis and factors affecting it after the pars plana vitrectomy (PPV) procedure. Methods In a prospective study, patients were recruited consecutively from October 2016 to June 2018. Upper eyelid margin reflex distance 1 and 2 (MRD1 and 2), upper eyelid crease height, and levator function were measured before, 1 and at least 6 months after surgery by the same investigator. Clinical and Clinically significant ptosis were defined as ≥0.5 and ≥2 mm drop of MRD1. Result There were 60 eyes from 57 patients. The majority of surgeries were performed by the fellows (63.3%, 38/60) and under general anesthesia (95.0%, 57/60). Clinical and clinically significant ptosis following PPV were 47.2% (25/53) and 11.3% (6/53) at the last follow up (at least 6 months), respectively. MRD2 (p = 0.389) and eyelid crease height (p = 0.057) did not significantly change. Surgeons' level, time of the procedure and other variables were not significantly impacting the frequencies. Conclusion Persistent clinically significant ptosis was observed in 11% of patients undergoing PPV. No variable was significantly associated with persistent postoperative ptosis after PPV.

Objective To compare the characteristics and outcomes of rhino-orbito-cerebral mucormycosis (ROCM) in diabetic versus non-diabetic patients. Method It is a retrospective comparative case series on consecutive patients with biopsy-proven ROCM. Systemic and ophthalmic manifestations, imaging, management and final outcomes were compared between diabetic versus non-diabetic ROCMs referred the eye clinic of a university-based hospital (2008-2016). Results Forty-three diabetics (55 eyes) with mean age of 54.6 (SD:12.5) years and 20 non-diabetics (24 eyes) with mean age of 57.5 (SD:13.8) years were enrolled. Patients' survival was observed in 51% of diabetics and 70% of non-diabetics (P = .1). The mortality rate was 7.4 times (CI95%: 1.85-29.96) higher in diabetic ROCM treated with non-liposomal amphotericin (P = .01). Exenteration did not significantly change the mortality rate in either group. Globe survival was 40% and 50% in diabetics and non-diabetics (P = 1), respectively. Vision survival was observed in 20% of diabetics and 37% of non-diabetics (P = .2). Conclusion Patients', globe and vision survivals were not different between diabetic and non-diabetic patients with ROCM. They were 51%, 40% and 20% in diabetic and 70%, 50% and 37% in non-diabetic ROCM.

Purpose To demonstrate the technique and report the results of endoscopic-assisted lateral orbitotomy for 6 patients with huge intraorbital dermoid cyst causing orbital roof bone erosion and dural invasion. Methods Patients had unilateral cystic tumor with proptosis and hypoglobus for more than 6 months. There was no compressive optic neuropathy. Lateral orbitotomy procedure was performed from 2004 to 2016 by 1 surgeon. Cysts were dissected, and fluid content was aspirated to reduce the size. Solid contents were then suctioned, its cavity was repeatedly irrigated, and orbital part of epithelial lining was removed. The remained epithelial lining and keratinized content at the orbital roof (abutting the dura) were removed using the rigid endoscope lenses (4 mm, 0° and 30°) and curettage. Orbital tissue was pulled away from the roof (inferior) by an assistant surgeon to make a space for introducing the lens and curette. The surgical field was frequently irrigated. No orbital drain was used, and all the patients were discharged on the same day after 8-10 hours of observation. Skin sutures were removed 1 week later. Results They were 4 men and 2 women with age range of 19-48 years. A large superolateral orbital tumor with roof erosion and dural invasion was observed on imaging. Procedures were performed uneventfully. Dermoid was the pathological diagnosis. While one patient lost to follow up after 1 week, others had 6-18 months follow-up time with no recurrence. Conclusions Endoscopic-assisted lateral orbitotomy approach provided a good field of view, illumination, and magnification to totally remove all the content and epithelial lining of very large orbital roof dermoid cysts with dural invasion.

Purpose of review After failed conservative management, most clinicians treat congenital nasolacrimal duct obstruction (CNLDO) in a conventional stepwise fashion: starting with probing, then repeat probing, next silicone intubation and/or balloon dilatation, and finally dacryocystorhinostomy. This approach is based on the patient's age and previously failed procedures and recruits 'one procedure for all' CNLDO. A newly introduced approach is based on the type of obstruction and recruits 'all procedures for one' CNLDO. The aim of this review is to examine the best available evidence regarding CNLDO management. Recent findings Recent articles support the concept that through intraoperative evaluation of obstruction in CNLDO, clinicians may predict probing failure and instantaneously employ more appropriate treatment modalities. This review addresses whether an age-based approach should be changed into a one-stage obstruction-based approach. Summary An age-based approach treats CNLDO as a homogeneous disease and thus treats all patients with one predetermined procedure. A one-stage obstruction-based approach, however, considers CNLDO to be a heterogeneous disease, and therefore allows recruitment of all procedures simultaneously and selects the best intraoperatively. It may allow replacement of the conventional stepwise approach to CNLDO treatment provided that randomized trials verify its efficacy, safety, and cost-effectiveness.Video abstract http://links.lww.com/COOP/A30.

Purpose To introduce a new (Supine) test and assess the values of lateral eyelid bulging for diagnosis of lacrimal gland (LG) prolapse before upper blepharoplasty. Methods In a prospective case series (2011-2017), lateral eyelid bulging and Supine Test were recorded, preoperatively. Lacrimal gland prolapse was graded as mild ( 7 mm). A few spots of cautery on LG capsule was performed in patients with bilateral mild and suture repositioning in unilateral or bilateral moderate and severe LG prolapse. Patients with asymmetric LG prolapse were treated based on more severe grade, bilaterally. Results Included were 1,207 patients. Frequency of positive Supine Test (11.8%, 142/1,207) increased from almost 10% in patients less than 41 years of age to 15% in more than 60 years of age. Their mean age was significantly older, and 53.2% showed asymmetric LG prolapse. Septum was just opened in patients with positive Supine Test, and all had LG prolapse of ≥3 mm (mean: 5.6 mm, range: 3-14 mm). Mild LG prolapse, moderate LG prolapse, and severe LG prolapse were observed in 22.5%, 62.6%, and 14.7% of the patients, respectively. Mean follow-up time was 22 months (12-60 months). Recurrence was observed in 1 patient (bilateral) after suture repositioning. Lateral eyelid bulging had a high negative (96.2%) and low positive (30.6%) predictive value when compared with the Supine Test. Conclusions Positive Supine Test means LG prolapse of ≥3 mm (100% positive predictive value). Negative lateral eyelid bulging was highly predictive of no LG prolapse.

To explore if the increased percentages of Regulatory T (Treg) cells, as well as, overexpression of Cytotoxic T-Lymphocyte Antigen-4 (CTLA-4) are involved in laryngeal-squamous cell carcinoma (SCC), 45 patients with laryngeal-SCC and 27 healthy controls were enrolled. Flow cytometry was performed to investigate, in the peripheral blood, the prevalence of CD4+CD25+FoxP3+ Treg cells, as well as, surface and intracellular expression of CTLA-4 by the main lymphocyte subsets (CD4+, CD8+ and CD19+). The results indicated intracellular (In)CTLA4 with considerable higher expression in the CD8+ lymphocytes among patients with laryngeal-SCC compared with the control group (8.2 ± 8.7 versus 2.3 ± 3.5, P = 0.001). The mean percentage of InCTLA4+CD4+ and InCTLA4+CD19+ lymphocytes was also significantly higher in patients (8.7 ± 7.8 versus 4.4 ± 4.2, P = 0.018 and 0.6 ± 0.8 versus 0.2 ± 0.2, P = 0.024, respectively). With respect to surface (Sur)CTLA4, the difference between patients and controls was, however, significant only in the case of CD8+ lymphocytes (0.7 ± 0.6 versus 0.3 ± 0.3, P = 0.003, respectively). The percentage of Treg cells was observed to be significantly higher in patients (7.5 ± 6.3 and 3.2 ± 1.9, P < 0.0001). Furthermore, association analysis revealed the association of Treg cell increase with the higher tumor-size and lymphnode stage (P < 0.005). These data collectively suggest that patients with laryngeal-SCC may benefit from immunotherapy targeting CTLA4 and Treg cells.

Objective:There is currently controversy over the association between serum interleukin-4 and -10 levels and head and neck squamous cell carcinoma in patients of different ethnicity. This study aimed to investigate serum levels of these cytokines in Iranian patients with this pathology, and to analyse correlations with tumour location and tumour stage at diagnosis.Design:Serum cytokines levels were quantified using commercial enzyme-linked immunosorbent assays.Subjects:Study groups comprised 93 untreated patients and 53 healthy donors.Results:Serum interleukin-4 levels were significantly increased in patients compared with controls (p Conclusion:Serum levels of interleukin-4, but not -10, were increased in Iranian head and neck squamous cell carcinoma patients. These data do not support an association of these cytokines with tumour progression; this is consistent with previous findings.
