Percutaneous endoscopic lumbar discectomy for L5-S1 disc herniation based on image analysis and clinical findings: A retrospective review of 345 cases.

The effect of spinal anatomical anomalies on the efficacy of percutaneous endoscopic lumbar discectomy (PELD) for disc herniation repair is unclear. This retrospective review aims to assess the safety and effectiveness of PELD for treating L5-S1 disc herniation with a range of characteristics and to determine the prevalence of lumbosacral transitional vertebrae (LSTV) anatomical anomalies to facilitate pre-surgical planning. From July 2005 to June 2019, 345 patients with L5-S1 disc herniations were treated with PELD.

Palatal hybrid surgery for obstructive sleep apnea-state-of-the-art annotation of uvulopalatopharyngoplasty.

Background: Surgery for obstructive sleep apnea (OSA) has changed in concept and technique that transformed from radical excision to functional reconstruction. The aim of this study was to investigate the safety and effectiveness of palatal hybrid surgery in OSA patients.

Methods: Palatal hybrid surgery is a tissue-specific technique (mucosa-preservation, tonsil-excision, fat-ablation, muscle-relocation/suspension) used in treating OSA patients with velopharyngeal obstruction.

Prediction of Epiglottic Collapse in Obstructive Sleep Apnea Patients: Epiglottic Length.

Objective: This study aims to explore the factors that contribute to epiglottic collapse (EC) in patients with obstructive sleep apnea (OSA).

Methods: This study enrolled 35 patients (34 males; median age, 39 years; median apnea-hypopnea index (AHI), 55.4 events/h; median body mass index (BMI), 26.

Idiopathic Sudden Sensorineural Hearing Loss in Patients with Obstructive Sleep Apnea.

Purpose: Obstructive sleep apnea (OSA) is characterized by recurring hypoxic-apneic events during sleep, and labyrinthine vascular compromise is a pathophysiologic hallmark of idiopathic sudden sensorineural hearing loss (ISSNHL). Some reports have discussed the relationship between OSA and hearing impairment; however, few have examined hearing prognosis in OSA and patients without OSA with ISSNHL. We aimed to investigate clinical manifestations of ISSNHL in patients with OSA, including severity of hearing loss and response to treatment.

How to manage continuous positive airway pressure (CPAP) failure -hybrid surgery and integrated treatment.

Obstructive sleep apnea (OSA) is a prevalent disease, which influences social relations and quality of life with major health impact. The etiology of OSA is multi-factorial involving both anatomical obstruction and physiological collapse of the upper airway during sleep with different proportion in individual patients. Continuous positive airway pressure (CPAP) is the gold standard and first-line treatment for OSA patients.

High elevation training mask as a respiratory muscle strength training tool for dysphagia.

Background: Expiratory muscle strength training (EMST) is a treatment for swallowing dysfunction due to its activation of the suprahyoid muscles. Current EMST devices have numerous limitations.

Objective: The purpose was to evaluate the utility of elevation training mask as an alternative respiratory muscle strength training (RMST) device.

Long-Term Effects of Intracapsular Debulking and Adjuvant Somatostatin Analogs for Growth Hormone-Secreting Pituitary Macroadenoma: 10 Years of Experience in a Single Institute.

Objective: Long-term effects of endoscopic endonasal transsphenoidal intracapsular debulking and adjuvant somatostatin analogs (SSAs) were evaluated in patients with growth hormone- (GH) secreting pituitary macroadenomas.

Methods: We retrospectively reviewed the medical records of 45 patients with acromegalic macroadenoma who underwent endonasal endoscopic transsphenoidal intracapsular debulking and received adjuvant SSAs (octreotide) between 2006 and 2015 who had >1 year of follow-up. To evaluate the predictive factors for 1 year and long-term biochemical outcomes, univariate and multivariate analyses were performed.

Treating cerebrovascular diseases in hybrid operating room equipped with a robotic angiographic fluoroscopy system: level of necessity and 5-year experiences.

Background: A hybrid operating room (OR) equipped with robotic angiographic fluoroscopy system has become prevalent in neurosurgery. The level of necessity of the hybrid OR in treating cerebrovascular diseases (CVD) is rarely discussed.

Objective: The authors proposed a scoring and classification system to evaluate the cerebrovascular procedures according to the level of treatment necessity for CVD in a hybrid OR and shared our 5-year experiences.

Endoscope-assisted transsphenoidal puncture of the cavernous sinus for embolization of carotid-cavernous fistula in a neurosurgical hybrid operating suite.

Endovascular embolization is the treatment of choice for carotid-cavernous fistulas (CCFs), but failure to catheterize the cavernous sinus may occur as a result of vessel tortuosity, hypoplasia, or stenosis. In addition to conventional transvenous or transarterial routes, alternative approaches should be considered. The authors present a case in which a straightforward route to the CCF was accessed via transsphenoidal puncture of the cavernous sinus in a neurosurgical hybrid operating suite.

Temporary clamping of bilateral external carotid arteries for surgical excision of a complex dural arteriovenous fistula.

Background: Some complex dural arteriovenous fistulas (DAVFs) are lesions that typically have numerous arterial feeders. Surgery, including resection of fistulas or skeletonization of the diseased sinus, is still one of the important treatments for these lesions. However, major blood loss is usually encountered during craniotomy because of abundant arterial feeders from the scalp and transosseous vessels.

Hybrid surgery for dural arteriovenous fistula in the neurosurgical hybrid operating suite.

Treatment of a dural arteriovenous fistula (AVF), which is difficult to access by either the surgical or endovascular approach, is challenging. A hybrid technique, combining a microsurgical approach and endovascular embolization, can provide less invasive management of dural AVFs in a modern neurosurgical hybrid operating suite. We present a case of intracerebral hemorrhage in the left cerebellum secondary to dural AVF, Cognard type IV with numerous tiny feeders from the ascending pharyngeal artery branches.
