RESUMO
BACKGROUND: Although the linear scalp incision is commonly used in neurosurgical practice, a systematic study elucidating its pros and cons in a specific surgical setting is lacking. Herein, we analyzed our experience with linear scalp incision in brain tumor surgery and the impact on intraoperative variables and postoperative complications. METHODS: Patients undergoing brain tumor surgery (January 2014-December 2021) at 2 neurosurgical departments were included and divided into 2 groups: linear or flap scalp incision. Patients' demographics characteristics, surgical variables, and wound-related complications were analyzed. RESULTS: More than a total of 1036 craniotomies, linear incision (mean length 6cm) was adopted in 282 procedures (27.2%). Mean maximum diameter of the craniotomy was 5.25 cm, with no statistical difference between the 2 groups. In emergency surgery (36 cases), the linear and flap incisions were used indifferently. Linear incision was predominant in supratentorial and suboccipital lesions. Flap incision was significantly more frequent among meningiomas (P < 0.01). Neuronavigation, operative microscope, and subgaleal drain were more frequently used in the flap scalp incision group (P = 0.01). Overall complication rate was comparable to flap scalp opening (P = 0.40). CONCLUSIONS: The use of the linear incision was broadly applied for the removal of supratentorial and suboccipital tumors granting adequate surgical exposure with a low rate of postoperative complications. Tumors skull base localization resulted the only factor hindering the use of the linear incision. The choice of 1 incision over another didn't show to have any impact on intraoperative and postoperative variables, and it remains mainly based on surgeon expertise/preference.

BACKGROUND: Patients aged >80 years frequently have intracranial meningiomas. In the present study, we have discussed the pathological features, comorbidities, and surgical complications for this age group from a surgical series and literature review. METHODS: In the present study, we reviewed a surgical series of 354 intracranial meningiomas and compared the oldest age group (age, ≥80 years) of 17 patients with 73 patients aged 70-79 years and 264 patients aged <70 years. From a literature review, we selected 10 studies of meningiomas in patients aged ≥80 years. The analyzed factors included sex, meningioma location, World Health Organization grade, Ki-67 MIB1, progesterone receptor expression, comorbidities, American Society of Anesthesiologists class, Karnofsky performance scale score, postoperative complications, and death. RESULTS: Patients aged ≥80 years had had higher rates of World Health Organization grade II meningioma, higher rates of Ki-67 expression of >4% and <20%, and progesterone receptor expression <15%. Of the postoperative complications, only neurological deficits and acute bronchopneumonia were significantly more frequent in patients aged ≥80 years. The incidence of intracerebral hematoma, lung embolism, acute heart ischemia, and death were not significantly different between the patients aged ≥80 years and those aged 70-79 years and <70 years. CONCLUSIONS: Patients aged ≥80 years must be considered a true elderly group with higher rates of comorbidities. The very old age is not a limitation to surgery; however, careful patient selection is necessary. In addition, for the oldest age group, the surgical decision should not be delayed because of advancing age.

Introdução: existem vários procedimentos para a correção cirúrgica de uma má oclusão de Classe II. Nas situações, onde o mento está bem posicionado na face, com sulco mentolabial profundos e uma relação de classe II por retrusão dentoalveolar, a técnica cirúrgica da osteotomia subapical representa uma opção de tratamento. Objetivos: mostrar a aplicabilidade da osteotomia subapical anterior mandibular em uma má oclusão anterior de classe II com retrusão dentoalveolar. Conclusão: a osteotomia subapical anterior mandibular corrigiu a má oclusão de classe II sem interfeir na posição do mento proporcionando assim uma boa harmonia facial.
