Abstract Objectives: Olfactory function is known to be modulated by repeated exposure odors. The aim of this investigation was whether patients with olfactory loss would benefit from “Training” odors in terms an improvement their general function. It hypothesized that Training should produce both improved sensitivity towards the used process and overall increase Study Design: prospective study performed dysfunction. Methods: One group (n = 40), whereas another part did not 16). Exclusion...
Objective Upper airway stimulation (UAS) is an alternative treatment option for patients unable to tolerate continuous positive pressure (CPAP) the of obstructive sleep apnea (OSA). Studies support safety and efficacy this therapy. The aim registry collect retrospective prospective objective subjective outcome measures across multiple institutions in United States Germany. To date, it represents largest cohort studied with Study Design Retrospective study. Setting Ten tertiary care hospitals...
Abstract Tracheal stenosis is commonly caused by injury, resulting in inflammation and fibrosis. Inhibiting promoting epithelization can reduce recurrence after initial successful treatment of tracheal stenosis. Steroids play an important role management. This study vitro evaluated effectiveness a polydopaminated polycaprolactone stent coated with dexamethasone‐eluting poly(lactic‐co‐glycolic) acid microparticles (μPLGA) for Polydopamination was characterized Raman spectroscopy promoted...
Abstract Objectives: Surgical management of long‐segment tracheal stenosis is an ongoing problem. Many types prostheses have been tried but with limited success because immune rejection, graft ischemia, or restenosis. Tissue engineered cartilage may offer a solution to this problem, although scaffolds, which are currently often used for support, can lead biocompatibility problems. This study investigated the feasibility scaffold‐free tissue engineer vascularized neotrachea in rabbits. Study...
Abstract Objectives/Hypothesis: Donor site morbidity, including pneumothorax, can be a considerable problem when harvesting cartilage grafts for laryngotracheal reconstruction (LTR). Tissue engineered may offer solution to this problem. This study investigated the feasibility of using autologous chondrocytes tissue‐engineer scaffold‐free LTR in rabbits avoid degradation that often arises from an inflammatory reaction scaffold carrier matrix. Study Design: Animal study. Methods: Auricular was...
Abstract Objectives: Donor site morbidity, including pneumothorax, can be a considerable problem when harvesting cartilage grafts for laryngotracheal reconstruction (LTR). Tissue‐engineered may offer solution to this problem. This study investigated the feasibility of using Hyalograft C combined with autologous chondrocytes tissue engineer LTR in rabbits. Study Design: Animal study. Methods: Eighteen New Zealand white rabbits underwent LTR: 12 received tissue‐engineered and 6 animals,...
Abstract Objectives/Hypothesis: Scaffold‐free cartilage has been used to engineer biocompatible and mechanically stable neotracheas in vivo. The purpose of this animal study was determine if neotracheal constructs, implanted paratracheally, could successfully be for segmental tracheal reconstruction. Study Design: Animal study. Methods: Culture‐expanded auricular rabbit chondrocytes were scaffold‐free sheets. Cartilage a strap muscle flap wrapped around tube paratracheally. At 12 14 weeks...
Scaffold-free cartilage engineering techniques may provide a simple alternative to traditional methods employing scaffolds. We previously reported auricular chondrocyte-derived constructs for use in an engineered trachea model; however, the construct generation were not detail. In this study, from and articular cell sources are described detail, resulting compared joint resurfacing model. Attachment of sheets porous tantalum is also investigated as potential vehicle future attachment...
Several prophylactic surgical methods have been tried to prevent CSF leakage after translabyrinthine resection of acoustic neuroma (TLAN). The authors report an improvised technique for multilayer watertight closure using titanium mesh-hydroxyapatite cement (HAC) cranioplasty in addition dural substitute and abdominal fat graft TLAN.The study was limited 42 patients who underwent TLAN at University Hospitals Case Medical Center this new from 2006 2012. Systematic the wound layers temporalis...
The only hypoglossal nerve stimulation (HNS) device available for US clinical use is implanted through 3 incisions. A recently proposed 2-incision modification moved the respiratory sensing lead from fifth to second intercostal space eliminate third lower chest incision. This study compared perioperative data and therapeutic outcomes between techniques.Noninferiority cohort analysis of a retrospective prospective registry study.Tertiary care community surgical centers.Patients with...
Objectives: The primary objectives were to report oncologic outcomes of transoral laser microsurgery with potassium-titanyl-phosphate (KTP) (TLM-KTP) ablation early glottic cancer (EGC). secondary vocal and analyze factors that might influence outcomes. Methods: A multi-institutional, retrospective analysis consecutive patients treated for T1 or T2 squamous cell carcinoma undergoing TLM-KTP at least 2 years follow-up was performed. Patients prior radiation surgery laryngeal disease excluded....
Hintergrund: Ein verlängerter Styloidfortsatz oder eine Verkalkung des Ligamentum stylohyoideum können als Styloidsyndrom mögliche Ursache für zervikale Schmerzen, Globusgefühl und Schluckprobleme sein. Die Behandlung differenzialdiagnostisch bei zervikalen Schmerzen wichtigen Styloidsyndroms ist facettenreich.
Hintergrund: Die Behandlung der subglottischen Stenose kann in Form einer laryngotrachealen Erweiterungsoperation oder cricotrachealen Resektion erfolgen. Patienten und Methoden: In retrospektiven Untersuchung wurden die Erfahrungen mit Erweiterung isolierter subglottischer Stenosen bei 37 (Alter: 3 - 78 Jahre; Stenosegrad: 20 × Grad II, 13 III, 4 IV) über einen Zeitraum von 30 Jahren erfasst. Ergebnisse: Eine erfolgreiche des Raumes (postoperativer Endoskopiebefund < %) war 33 (89,2...
Neurothekeomas are benign tumours mostly arising in the face and upper limbs predominantly young women. Histologically they can be classified as cellular or myxoid, complete surgical resection is treatment of choice. In this case a neurothekeoma located anterior tongue child, cryotherapy was used modality, order to avoid greater loss function.
Cricotracheal resection (CTR) has been shown to be successful in the treatment of pediatric subglottic stenosis. Whether CTR combined with posterior midline division or partial cricoid plate affects stability and growth larynx is still questionable. The study included 24 infant female New Zealand White rabbits that were divided into 4 groups 6 animals each. Group 1 was unoperated control group. 2 underwent removal three quarters anterior circumference, followed by a primary anastomosis...
Synchronous primary tumors (SPTs) are detected via triple endoscopy or positron emission tomography/computed tomography (PET/CT). Patients with human papillomavirus-associated oropharyngeal squamous cell carcinoma (HPV+ OPSCC) lack risk factors for SPTs.We performed a single institution retrospective review of the efficacy and PET/CT in HPV+ OPSCC patients.Sixty-five patients underwent PET/CT. were white (n = 48, 72.7%), male 53, 81.5%), mean 58.7 ± 8.1 years old. SPT was 1 (1.5%) patient No...
