Evolution of a paradigm for free tissue transfer reconstruction of lateral temporal bone defects.

BACKGROUND: Tumors of the lateral skull base are best treated with surgery plus or minus radiation therapy. Surgical ablation may involve cutaneous structures, the auricle, the parotid, and the lateral temporal bone. These composite soft tissue defects are best reconstructed with composite tissue. Multiple pedicled flaps have been used to reconstruct these defects. Free flaps have been shown to provide the best tissue for these reconstructions. We review our experience and present an algorithm for their reconstruction. METHODS: A case series of consecutive patients treated between 1999 and 20

Wheel-shaped cartilage-perichondrium composite graft for the prevention of retraction pocket development.

CONCLUSION: Our technique can decrease the formation of retraction pockets and improve hearing function. The wheel-shaped cartilage-perichondrium composite graft (Wheel CPCG) can be considered a good material for a drum graft, and it is easy to insert a ventilation tube, in case of initial drum retraction. OBJECTIVE: The purpose of this study was to introduce the novel surgical technique of a Wheel CPCG with one-stage ossiculoplasty to prevent a retraction pocket and subsequent cholesteatoma after intact canal wall tympanomastoidectomy. PATIENTS AND METHODS: A total of 47 patients were revie…

Decongestants and antihistamines for acute otitis media in children.

RATIONALE: Acute otitis media (AOM) is one of the most common bacterial infections in children worldwide, and the most common reason for prescribing antibiotics. Although serious complications (e.g. mastoiditis or meningitis) are rare, the infection causes acute pain and can lead to hearing impairment. Since AOM often resolves spontaneously, current treatment guidelines recommend an approach of watchful waiting (no initial antibiotics). However, decongestants and antihistamines, administered orally or nasally, might reduce inflammation and mucosal oedema in the middle ear and help resolve AOM …

Preliminary outcomes of endoscopic middle-ear surgery in 103 cases: a UK experience.

BACKGROUND: Totally endoscopic ear surgery and endoscope-assisted microsurgery are still new concepts, with relatively few centres in the UK performing them. Advantages include better visualisation of difficult to reach areas, such as the sinus tympani, and limited external incisions. This paper reports our short-term outcomes for endoscopic middle-ear surgery. METHODS: A prospective review was conducted of the first 103 consecutive patients undergoing totally endoscopic ear surgery or endoscope-assisted microsurgery in 1 centre performed by 1 operator. The outcomes assessed were: tympanic me

[Vertigo in the Emergency Department: new bedside tests].

According to international statistics, the first examination of 25% of patients with vertigo is carried out in Emergency Departments. The most important task of the examining physician is to diagnose life threatening pathologic processes. One of the most difficult otoneurological diagnostic challange in Emergency Departments is to differentiate between dangerous posterior scale stroke presenting with isolated vertigo and the benign vestibular neuritis.These two disorders can be safely differentiated using fast, non-invasive, evidence based bedside tests which have been introduced in the past f

A 43-year-old woman presenting with subacute, bilateral, sequential facial nerve palsies, then developing pseudotumour cerebri.

A patient presented elsewhere with what appeared to be a simple, unilateral, chronic suppurative otitis media and then developed an ipsilateral facial palsy. She soon developed the same problem on the other side. At the time, a brain MRI had been ordered but the clinician did not review it with a radiologist. The surgical specimens were not sent for histopathology. When transferred to our institution 3 months later, the patient had severe bilateral papilloedema due to intracranial hypertension due to missed cerebral venous sinus thrombosis. Further surgery revealed that the pathology in the te

Improved facial nerve outcomes using an evolving treatment method for large acoustic neuromas.

OBJECTIVE: To describe a successful paradigm for the treatment of large acoustic neuromas (vestibular schwannomas). STUDY DESIGN: Retrospective case review. SETTING: Tertiary referral center. PATIENTS: The charts of 2,875 acoustic neuroma patients at Michigan Ear Institute were reviewed to identify 153 patients who underwent surgical resection for large acoustic neuromas (>=3 cm) between 2000 and 2009. INTERVENTION(S): Staged surgical resection or single stage surgery with or without adjuvant stereotactic radiosurgery. MAIN OUTCOME MEASURE(S): Postoperative facial nerve outcomes are repor

An evidence-based algorithm for intraoperative monitoring during cochlear implantation.

OBJECTIVE: To generate an evidence-based algorithm for the use of intraoperative testing during cochlear implantation (CI). STUDY DESIGN: Retrospective review. SETTING: Tertiary referral center. PATIENTS: A total of 277 children (aged 6 mo to 17 yr) and adults 18 years and older with normal cochlear anatomy who underwent primary and revision cochlear implantation at a single center between 2005 and 2010 were included. INTERVENTION: Intraoperative electrophysiologic monitoring and intraoperative Stenver's view plain film radiography. MAIN OUTCOME MEASURE: Intraoperative testing included th

Point-to-point registration with mandibulo-maxillary splint in open and closed jaw position. Evaluation of registration accuracy for computer-aided surgery of the mandible.

INTRODUCTION: Computer navigation plays an increasingly important role in craniomaxillofacial surgery. The difficulties in computer navigation at the craniomaxillofacial site lie in the accurate transmission of the dataset to the operating room. This study investigates the accuracy of the dental-splint registration method for the skull, midface, and mandible. MATERIAL AND METHODS: A synthetic human skull model was prepared with landmarks and scanned with cone beam computer tomography (CBCT). Two registration splints fixed the mandible against the viscerocranium in two different positions (clo

Clinical analysis of intratympanic tympanosclerosis: etiology, ossicular chain findings, and hearing results of surgery.

CONCLUSION: The success rate (57.5%) in this study is not high for surgical treatment of tympanosclerosis, and therefore lends further evidence that intratympanic tympanosclerosis has been considered intractable for reconstructive surgery. OBJECTIVE: To investigate the clinical findings and surgical results of intratympanic tympanosclerosis. METHODS: From January 1989 to December 2006, a total of 1523 tympanoplasties were performed. Of these, 84 tailored tympanomastoidectomies were performed for tympanosclerosis in 80 patients. RESULTS: The incidence of intratympanic tympanosclerosis with c…

Vestibular evoked myogenic potentials in chronic otitis media before and after surgery.

CONCLUSION: The pathology of chronic otitis media (COM) could delay and reduce the energy transfer of sound to the inner ear. The significant improvement of postoperative vestibular evoked myogenic potential (VEMP) response rate and p13 latencies in the group of patients with no or negative postoperative ABG gain provided evidence that the sound energy inducing a VEMP might be different from the energy producing the auditory perception. OBJECTIVE: To evaluate the VEMP in patients with COM before and after surgery. SUBJECTS AND METHODS: Twenty-four subjects with unilateral COM were enrolled.

Zygomatic root approach.

CONCLUSIONS: The zygomatic root (ZR) approach provides improved intraoperative exposure of the key areas around the geniculate ganglion without a craniotomy, combining the advantages of middle cranial fossa (MCF) and transmastoid extralabyrinthine (TMEL) approaches. The ZR approach may be useful in cases of traumatic facial palsy, Bell's palsy, iatrogenic facial palsy, superior semicircular canal dehiscence and primary cholesteatoma. OBJECTIVES: To describe and evaluate the new ZR approach technique in the treatment of traumatic intratemporal facial nerve injuries. PATIENTS AND METHODS: This…

Microvascular decompression for glossopharyngeal neuralgia: a long-term retrospectic review of the Milan-Bologna experience in 31 consecutive cases.

OBJECTIVE: To examine surgical findings and results of microvascular decompression (MVD) for glossopharyngeal neuralgia (GN). METHODS: Between 1990 and 2007, 31 consecutive patients affected by drug-resistant GN underwent MVD through a retromastoid keyhole in the supine position with the head rotated to the opposite side. A retrospective analysis was performed that paid particular attention to the relationship among surgical technique, pain control and side effects. RESULTS: A vascular compression of the glossopharyngeal nerve was found in all cases. Twenty-eight out of 31 patients (90.3%) w…
