“…MMA is a very effective and highly successful treatment method for OSA that increases the volume of the entire upper airway by moving the maxillomandibular complex forward through Le Fort I osteotomy of the maxilla and BSSRO of the mandible. Therefore, the preparations and procedures of the operation are the same as orthognathic surgery 5–7…”

“…Maxillomandibular advancement is a procedure that increases the total upper airway volume through forward movement of the maxilla through Le Fort I osteotomy and forward movement of the mandible through bilateral sagittal split ramus osteotomy (BSSRO) and has the same process as orthognathic surgery 6,7. However, since patients with OSA often have skeletal class II malocclusion, condyle positioning of proximal segment during BSSRO is difficult, and accurate condyle positioning is also required for patients undergoing MMA without orthodontic treatment.…”

cellular subtype. Another classification involves cellular morphology. The 2 patterns of cell morphology are Antoni A and Antoni B. In Antoni A, spindle cells are arranged in "interlacing cords, whorls, or palisades," whereas Antoni B is characterized by "stellate cells, with a mucoid stroma." 1 Treatment of orbital schwannomas is mainly surgical. The surgical approach differs depending on the localization of the tumor 1,4 and may occasionally require an interdisciplinary approach between ophthalmology, otorhinolaryngology, and neurosurgery. Surgical excision is considered a definitive treatment, with recurrence rates being very low. 4,7 In our case, we opted for a superior orbitotomy through a lid-split incision. This approach provided us adequate visualization of the schwannoma, which was in the central, anterior orbit. It also allowed an excellent view of the bony defect of orbital roof in the event a reconstruction was needed. Though rare, potential risks unique to this approach are those involving the eyelid margin, including notching, trichiasis, and irregular contour.We believe the patient's acute presentation of symptomatic diplopia is explained by the intralesional hemorrhage seen on MRI, which may have increased the lesion's size abruptly. It is interesting to note the absence of lid retraction in the patient's postoperative period despite having underwent 2 levator palpebrae resections; we hypothesize that the muscle was mechanically stretched by the tumor throughout the years.We believe our case is unique, given the patient's clinical course as well as the surgical approach through vertical lid-split incision technique. The intraoperative view of the defect in the orbital roof was equally special. We hope this report serves as a reminder to retain diagnostic skepticism in the face of recurrent ptosis and to consider vertical lid-split approach for anterior lesions of the orbit.

“…Some hematological and biochemical markers of inflammation were found to be associated with the presence or prognosis of several cancer types. [14,15] NLR and MPV are easily performed in daily routine at every clinics including primary health care clinics. Nevertheless, the clinical significance of these markers for metastasis in lung cancer patients is unclear.…”

Chronic inflammation plays an important role in the etiopathogenesis of many life-threatening chronic diseases, including cancer. Currently, the relationship between inflammation, native immunity and cancer is widely accepted; however, many of the mechanisms mediating this relationship remain undetermined and the clinical significance of these markers is unclear. The purpose of this study was to investigate the potential of neutrophil-lymphocyte ratio (NLR) and mean platelet volume (MPV) to indicate the existence of metastasis in lung cancer. This retrospective cross-sectional study evaluated patients with lung cancer of any pathological type who was admitted to the Palliative Care Unit of the referral hospital in the region between January 2019 and February 2020. Patient characteristics, distant organ metastasis, treatments, NLR and MPV values were noted. Patients were grouped as with or without metastasis. Characters, NLR, MPV values were compared. One hundred twenty-six patients were included. The mean age of the patients was 61.17 ± 9.4 years and 7.9% (n = 10) were female. The patients with a history of chemotherapy were 47% (n = 60) and distant organ metastases were present in 38.9% (n = 49) of the patients. The mean MPV value of 49 patients with distant metastasis was 8.34 ± 0.8 fL. MPV values of those with metastasis were found to be significantly higher than those without (P = .010). There was no significant difference in NLR values between groups (P = .920). Lung cancer patients with metastasis were found with higher MPV values. MPV can be effective and most accessible test in prediction of metastasis in lung cancer patients regardless of the pathological type.
