“…The UBA has been used in a wide range of fields, including skull base surgery ( 12 – 14 ), orbital and lacrimal sac surgery ( 15 – 17 ), and spine surgery ( 18 – 21 ). In the field of otorhinolaryngology, the UBA has been used for facial nerve decompression surgery ( 10 ), frontal sinus osteoma removal ( 22 – 24 ), transcanal endoscopic ear surgery ( 25 ), extended frontal sinusotomy ( 26 ), septoplasty and inferior turbinectomy ( 27 , 28 ), endoscopic posterior split and cartilage graft laryngoplasty ( 29 ), retrosigmoid craniotomy ( 30 ), and septorhinoplasty ( 31 – 33 ). However, no previous studies have described the application of the UBA in EMMM.…”

BackgroundEndoscopic modified medial maxillectomy (EMMM) is a surgical technique developed to approach maxillary sinus lesions, such as papilloma and postoperative maxillary cyst, while preserving the postoperative nasal morphology and nasal function. In this technique, a diamond burr is used to remove the bone, which may damage adjacent soft tissue. We developed EMMM using an ultrasonic bone aspirator (UBA) instead of a conventional diamond burr. The purpose of this study was to clarify the effectiveness of the UBA in EMMM in comparison to the conventional diamond burr technique in terms of operative time, intraoperative complications, postoperative symptoms, and recurrence.MethodsThe medical records of all patients who underwent EMMM at Toyama University Hospital between June 2014 and December 2021 were reviewed. Patients who met the inclusion criteria were separated into Group 1, in which the UBA was used for EMMM, and Group 2, in which a drill with a diamond burr was used. Data on patient demographics, operation time, frequency of intraoperative complications and postoperative symptoms, and recurrence were statistically compared between the two groups.ResultsThere were no significant differences between the two groups in the patient demographic data, operative time, postoperative symptoms, or frequency of recurrence. The frequency of intraoperative damage to adjacent soft tissues was significantly lower in patients who underwent EMMM with the UBA in comparison to those who underwent EMMM with a conventional diamond burr.ConclusionThe application of the UBA to EMMM can improve surgical safety and facilitate surgical procedures.

“…The UBC permits precise graded removal of bone without damage to the surrounding nasal soft tissue or mucosa (39). Previous studies have reported the applications of the UBC in various otorhinolaryngological surgeries to prevent accidental injuries to the adjacent soft tissue or vital structures (40)(41)(42)(43)(44)(45)(46)(47)(48). The use of UBC in septoplasty and turbinoplasty, submucosal dissection of septal spur, bony septum, and bone of inferior turbinate, and was associated with a good prognosis and fewer surgical complications in comparison of the use of a microdebrider (40,44,48).…”

Localized Amyloidosis of the Nasal Mucosa: A Case Report and Review of the Literature

et al. 2021

View full text Add to dashboard Cite

Amyloidosis is a disorder of protein folding in which various proteins automatically aggregate into a highly abnormal fibrillar conformation. Amyloidosis is classified into systemic and localized forms depending on whether the abnormal proteins deposited in several different organs or only a single organ. In localized amyloidosis of the head and neck regions, laryngeal amyloidosis is common; however, localized amyloidosis of the nose is extremely rare. We herein report a case of localized amyloidosis of the nose and review the relevant literature on localized sinonasal amyloidosis. A 41-year-old man presented with a history of severe nasal obstruction, which had persisted for two decades. Nasal endoscopy and imaging studies showed extensive thickening of the bilateral nasal mucosa and diffuse submucosal deposition of calcification. After histopathological and systemic examinations, he was diagnosed with localized amyloidosis of the nasal mucosa. Septoplasty and bilateral inferior turbinoplasty, which consisted of mucosal resection using an ultrasonic bone curette, was performed and his symptoms markedly improved. Localized sinonasal amyloidosis has a good prognosis and surgical resection should be selected as a first-line treatment; however, clinicians should recognize the high probability of recurrence.

“…A meningioma can be hard in consistency due to calcification and its resection requires a potent UA device that handles solid tissue safely. Since the Sonopet can also be used as a bone aspirator [11], our surgeons tend to choose this model for meningioma resections, which can be appreciated in this study: the Sonopet was used in n = 126 meningioma cases, whereas the CUSA and the Söring were used in n = 105 and n = 49 cases, respectively. The CUSA is particularly well-known for its precision [9, 17], the possibility of “tissue select” allowing to adjust the tissue-specific aspiration strength, and its broad choice of tips with different shapes and lengths.…”

Ultrasonic aspiration in neurosurgery: comparative analysis of complications and outcome for three commonly used models

IntroductionUltrasonic aspiration (UA) devices are commonly used for resecting intracranial tumors, as they allow for internal debulking of large tumors, hereby avoiding damage to adjacent brain tissue during the dissection. Little is known about their comparative safety profiles.Methods and materialsWe analyzed data from a prospective patient registry. Procedures using one of the following UA models were included: Integra® CUSA, Söring®, and Stryker® Sonopet. The primary endpoint was morbidity at discharge, defined as significant worsening on the Karnofsky Performance Scale. Secondary endpoints included morbidity and mortality until 3 months postoperative (M3), occurrence, type, and etiology of complications.ResultsOf n = 1028 procedures, the CUSA was used in n = 354 (34.4 %), the Söring in n = 461 (44.8 %), and the Sonopet in n = 213 (20.7 %). There was some heterogeneity of study groups. In multivariable analysis, patients in the Söring (adjusted odds ratio (aOR) 1.29; 95 % confidence interval (CI), 0.80–2.08; p = 0.299), and Sonopet group (aOR, 0.86; 95 % CI, 0.46–1.61; p = 0.645) were as likely as patients in the CUSA group to experience discharge morbidity. At M3, patients in the Söring (aOR, 1.20; 95 % CI, 0.78–1.86; p = 0.415) and Sonopet group (aOR, 0.53; 95 % CI, 0.26–1.08; p = 0.080) were as likely as patients in the CUSA group to experience morbidity. There were also no differences for M3 morbidity in subgroup analyses for gliomas, meningiomas, and metastases. The grade (p = 0.608) and etiology (p = 0.849) of postoperative complications were similar.ConclusionsNeurosurgeons select UA types with regard to certain case-specific characteristics. The safety profiles of three commonly used UA types appear mostly similar.Electronic supplementary materialThe online version of this article (10.1007/s00701-019-04021-0) contains supplementary material, which is available to authorized users.
