After endoscopic endonasal reduction (EER) for medial blowout fracture (BOF), nasal packing may be necessary for sustaining the reduced orbital contents. This study aimed to introduce a new packing technique using Merocel in a glove finger. We retrospectively reviewed 131 patients with a mean age of 42.2 years (range, 13-80 years), who underwent EER for medial BOF, followed by a postoperative nasal packing of Merocel in a glove finger, between March 2016 and December 2019. ⋯ Three patients had diplopia and 1 had enophthalmos at final follow-up. No other major postoperative complications were noted. Merocel in a glove finger packing technique proved itself to be safe and effective after EER for medial BOF.

Orbital schwannomas are a rare disease, representing about 1% of orbital tumors, potentially involving any subsite within the orbit. They usually present with painless, nonpulsatile proptosis, while diplopia and vision impairment due to extrinsic ocular muscles or optic nerve involvement are rarely observed.1 A wait-and-see policy is advocated in case of small asymptomatic lesions. However, if progressive dimensional increase or symptoms are observed, surgical resection represents the treatment of choice.2 Different surgical approaches have been proposed, mainly depending on tumor dimension and location inside the orbit, as well as surgical expertise. ⋯ The lesion was completely removed with an endoscopic transnasal approach (Video 1), without evidence of postoperative sequelae or visual impairment. Magnetic resonance imaging performed 3 months after surgery showed good surgical results without evidence of persistence of disease. A multidisciplinary approach, involving different specialists familiar with orbital anatomy and physiology, is required for a proper management of patients affected by orbital pathologies.

Observational StudyCardiovascular dynamics during peroral endoscopic myotomy for esophageal achalasia: a prospective observational study using non-invasive finger cuff-derived pulse wave analysis.
Peroral endoscopic myotomy (POEM) is natural orifice transluminal endoscopic surgery to treat esophageal achalasia. During POEM, cardiovascular dynamics can be impaired by capnoperitoneum, capnomediastinum, and systemic carbon dioxide accumulation. We systematically investigated changes in cardiovascular dynamics during POEM. ⋯ HR (median at baseline: 67 (60;72) bpm), CI (2.8 (2.5;3.2) L/min/m2), SVI (42 (34;51) mL/m2), and SVRI (1994 (1652; 2559) dyn × s × cm-5 × m-2) remained stable during POEM. Mixed model-derived 95% confidence limits of hemodynamic variables during POEM were 72 to 106 mmHg for MAP, 65 to 79 bpm for HR, 2.7 to 3.3 L/min/m2 for CI, 37 and 46 mL/m2 for SVI, and 1856 and 2954 dyn × s × cm-5 × m-2 for SVRI. POEM is a safe procedure with regard to cardiovascular dynamics as it does not markedly impair MAP, HR, CI, SVI, or SVRI.

Adult craniopharyngiomas are low-grade tumors of the pituitary infundibulum that can be locally aggressive and frequently present with profound visual deficits and endocrinopathies. Surgical resection remains the preferred initial treatment for these lesions, and recently endoscopic endonasal approaches (EEAs) have become increasingly used. However, minimal data exist comparing these techniques with traditional transcranial (TC) methods. The purpose of this study was to evaluate perioperative differences in EEA and TC approaches for adult craniopharyngiomas over the past several decades. ⋯ Over the past several decades, utilization of EEAs to resect adult craniopharyngiomas has increased. EEAs appear to be associated with lower rates of perioperative mortality and complications. However, long-term, prospective studies controlling for tumor size, location, and preoperative symptomatology are needed to determine when one approach should be used preferentially over the other.
