Improvement in fiber optics and imaging paved the way for tremendous advancements in neuroendoscopy. These advancements have led to increasingly widespread use of the endoscope in neurosurgical procedures, which in turn incited a technological revolution leading to new approaches, instruments, techniques, and a diverse armamentarium for the treatment of a variety of neurosurgical disorders. Soft-tissue removal is often a rate-limiting aspect to endoscopic procedures, especially when the soft tissue is dense or fibrous. The authors review a series of cases involving patients treated between August 2009 and October 2010 with a new device (the NICO Myriad), a non–heat-generating, oscillating, cutting, and tissue removal instrument that can be used through the working channel of the endoscope as well as in open neurosurgical procedures. They used this device in 14 purely endoscopic intracranial procedures and 1 endoscope-assisted keyhole craniotomy. They report that the device was easy to use and found that tissue resection was more efficient than with other available endoscopic instruments, especially in the resection of fibrotic tissue. There were no observed device-related complications. The authors discuss the technical aspects of using this device in endoscopic resection of pituitary tumors, craniopharyngiomas, and colloid cysts. They also demonstrate its use in hydrocephalus and intraventricular clot removal and discuss its potential use in other neurosurgical disorders.

The deviated external nose remains a difficult technical challenge to even the most masterful rhinoplastic surgeon. The classic septorhinoplasty approach to the deviated nose demonstrated a 9.8% revision rate in this study. During a 2-year period, the conservative subtraction-addition rhinoplasty procedure was developed, which subsequently reduced the revision rate to 1.3%. Conservative subtraction-addition rhinoplasty foregoes aggressive septal surgery and equalizes and enhances the airway through asymmetric turbinate volume reduction. Minimal bony and upper lateral work through rasping, soft tissue removal, and/or cartilage grafting allows for external nasal alignment. Both internal and external conservative subtraction-addition rhinoplasty components thus maintain perioperative structural stability and ensure long-term nasal symmetry.

The ventilating tracheal resectoscope (Karl Storz) combines the advantages of a ventilating bronchoscope and the resecting cystoscope for removal of soft tissue from the airway. The resectoscope offers several distinct advantages over other methods of granulation tissue removal. The procedure is done under direct vision with magnification and illumination of a rod-lens optical system. Suprastomal granulation tissue is resected cleanly, without tearing or stripping of adjacent mucosa. Hemorrhage is readily controlled with the coagulating mode. The resectoscope can also be used for removing benign tumors (such as recurrent respiratory papillomatosis) from the trachea and bronchi. Its use in the efficient removal of malignant tumors and subglottic soft tissue has also been described.

AbstractWe developed a non-destructive and rapid whole-mount bone staining method for small fish, Xenopus laevis, and rodent fetuses (RAP-B). RAP-B does not require skin or soft tissue removal. However, RAP-B requires hair removal from hairy animals, such as adult mice and rats. In the present study, we investigated hair removal chemical treatments that did not result in soft tissue destruction. The hair removal effectiveness was investigated using a calcium mercaptoacetate or sodium mercaptoacetate solution on skin fragments obtained from the back of adult mice. A mixture of 2% sodium mercaptoacetate in 3% potassium hydroxide was found to be the most effective in complete hair removal from the skin. Using this hair removal treatment as a pretreatment for RAP-B, the preparation of fast-acting artifact-free whole-mount bone staining was possible without skin and soft tissue removal (RAP-B/HR). We performed a seamless observation from a low magnification wide-view to a high magnification without artifactacting artifacts using fluorescence zoom microscopy. Therefore, the combination of RAP-B/HR and fluorescent zoom microscopy is a novel platform for three-dimensional, wide-field, high-resolution pathological anatomical analysis.

AbstractObjective:To compare the skin-related complications of the traditional skin flap method with a linear incision method of implantation.Method:All cases of bone-anchored hearing aid surgery performed by a single surgeon (n= 117) were compared over two periods: 1999–2011, when the traditional method of skin flap and soft tissue removal was used (group 1;n= 86), and 2012–2013, when linear incision without soft tissue removal was used (group 2;n= 31). All patients were followed up for one year and complications were recorded for that period.Results:There were 21 (24.4 per cent) skin-related complications in group 1 (skin overgrowth = 12, wound infection = 8 and numbness = 1) and 3 (9.7 per cent) complications in group 2 (wound infection = 3). Analysis using independentt-tests showed the results to be significant (p< 0.05; 95 per cent confidence interval = 0.0800–0.4473).Conclusion:The linear incision without soft tissue removal method for bone-anchored hearing aid implantation reduces skin complication rates.

Abstract Background p-PECD is an effective strategy for cervical diseases which working cannula ranges from 3.7 mm to 6.9 mm. However, no studies were performed to compare the clinical outcomes of keyhole technique (diameter of 3.7 mm) and delta technique (diameter of 6.9 mm) in CDH patients. The purpose of this study was to compare the clinical outcomes of unilateral cervical disc herniation (CDH) patients treated with posterior percutaneous endoscopic cervical discectomy (p-PECD) applying the keyhole technique with those treated with the delta technique.Methods From January 2016 to June 2018, totally 28 consecutive patients presented with single-level CDH who received p-PECD using the keyhole technique or the delta technique were enrolled in this study. Patients were evaluated neurologically pre- and postoperatively. The clinical outcomes, including the operation time, the hospitalization, the visual analogue scale (VAS) and the modified MacNab criteria, were evaluated. Cervical fluoroscopy, CT, and MRI were performed during follow up.Results In both groups, faster “V” point identification, more quickly overlying soft tissue removal and laminoforaminotomy, and shorter operative time, were found in the delta group. Postoperatively, the VAS and MacNab scores of the two techniques were improved significantly. Nevertheless, the differences between the two groups were not significant (P>0.05). One case suffered nerve root outer membrane torn in delta group.Conclusion Both keyhole technique and delta technique are effective methods for CDH in selected patients, and there is no significant difference in clinical outcomes. Delta technology is superior to keyhole technology in the efficiency of “V” point identification, overlying soft tissue removal and spinal cord injury prevention. Furthermore, delta technology is inferior to keyhole technology in anterior decompression of the intervertebral foramen.
