Effect of a fixed combination of nimodipine and betahistine versus betahistine as monotherapy in the long-term treatment of M\ue9ni\ue8re's disease: a 10-year experience

Despite an abundance of long-term pharmacological treatments for recurrent vertigo attacks due to M\ue9ni\ue8re's disease, there is no general agreement on the their efficacy. We present the results of a retrospective study based on a 10-year experience with two long-term medical protocols prescribed to patients affected by M\ue9ni\ue8re's disease (diagnosed according to the American Academy of Otolaryngology-Head and Neck Surgery Committee on Hearing and Equilibrium guidelines) who completed treatments in the period 1999-2009. A total of 113 medical records were analysed; 53 patients received betahistine-dihydrochloride at on-label dosage (32 mg die) for six months, and 60 patients were treated with the same regimen and nimodipine (40 mg die) as an add-therapy during the same period. Nimodipine, a 1,4-dihydropyridine that selectively blocks L-type voltage-sensitive calcium channels, has previously been tested as a monotherapy for recurrent vertigo of labyrinthine origin in a multinational, double-blind study with positive results. A moderate reduction of the impact of vertigo on quality of life (as assessed by the Dizziness Handicap Inventory) was obtained in patients after therapy with betahistine (p 0.05), whereas the fixed combination of betahistine and nimodipine was associated with a significant reduction of tinnitus annoyance and improvement of hearing loss (p < 0.005). It was concluded that nimodipine represents not only a valid add-therapy for M\ue9ni\ue8re's disease, and that it may also exert a specific effect on inner ear disorders. Further studies to investigate this possibility are needed

Prelaminated flaps in head and neck cancer reconstructive surgery: A systematic review

Background: Prelamination is a reconstructive technique providing fasciomucosal or composite flaps with low donor-site morbidity. We conducted a systematic review of retrospective studies to assess the application of prelaminated flaps in reconstructive surgery of head and neck cancer patients, and to evaluate the advantages and disadvantages of this technique. Methods: This systematic review adhered to the recommendations of the PRISMA (Preferred Reporting Items of Systematic Reviews and Meta-analysis) 2009 guidelines. A computerized MEDLINE search was performed using the PubMed service of the U.S. National Library of Medicine (www.pubmed.org) and Scopus database (www.scopus.com), running the following search string: “prelamination OR prelaminated AND flap.” Two authors screened the articles, then selected and extracted data on malignancies characteristics, reconstructive techniques, outcomes and complications. Results: A total of 19 articles were selected and reviewed from 128 identified. Seven of 19 articles were case reports, 12 articles were case series. One-hundred-two patients underwent reconstructive treatment by prelamination technique using a wide variety of flaps (92 free, 10 pedicled). The sites of reconstruction were oral cavity (66 floor of the mouth, 3 retromolar trigone, 6 hard palate, 4 cheek, 4 tongue), 8 facial skin (5 of them sited on the nose), 4 oropharyngeal defects, 1 laryngotracheal region. No case of total flap loss was reported. Partial flap loss or shrinkage requiring minor surgical revisions was observed in 18 patients (17.6%). Primary closure of the donor site was achieved in 97 cases (97%) and 3 (3%) required revision surgery of the donor site. Conclusion: Prelamination is an effective and versatile technique, with low donor-site morbidity. Further studies would be needed to investigate the impact on the patient's oncologic outcome. More comparative studies with standard reconstructive techniques are essential to understand when it is worth performing this sophisticated procedure

Anatomic and radiologic relationships of neck structures to cervical spine: Implications for anterior surgical approaches

The position of the pharyngolaryngeal framework is very important in choosing the best surgical approach for cervical spine disease. The aim of the present paper is to investigate the position of the hyoid bone and cricoid cartilage in relation to the cervical spine. Moreover, the surgical implications for anterior transcervical approaches to the upper spine and the prevertebral space are discussed. To minimise complication rates and increase surgical effectiveness, the location and extent of the cervical spine disease should be evaluated in the context of the patient’s specific anatomy. A retrospective analysis of 100 cervical spine MRIs was conducted. Patients with diseases that could alter anatomic relationships of cervical structures were excluded. The mid-sagittal view of the hyoid and the inferior margin of the cricoid cartilage were projected perpendicularly to the anterior surface of the cervical vertebrae. The distance between these two landmarks was measured on the same view. The distribution of hyoid projections ranged between C2-C3 and C4-C5 intervertebral space, while the cricoid cartilage ranged between C4-C5 and C7-T1 intervertebral spaces. The mean distance between these two landmarks was 49.1 ± 7.7 mm, with statistically significant differences between males and females. The position of the cricoid cartilage significantly influenced the length of the pharyngolaryngeal framework, while the position of hyoid did not. A wide range of variability in the position of the hyoid bone and the cricoid cartilage in relation to cervical levels exists. This implies that an a priori association of a cervical level to neck structures at risk might be inaccurate. The use of these easily identifiable landmarks on pre-operative imaging may help to guide the choice among different anterior surgical approaches to cervical spine and reduce the risk of surgical complications

Supracricoid partial laryngectomy in the management of t3 laryngeal cancer

Objective. To evaluate the oncologic results only in T3 glottic and supraglottic cancers regarding supracricoid partial laryngectomy (SCPL) not requiring total laryngectomy and to assess functional results by self-evaluation by the patient. Study Design. Case series with medical record review. Setting. Single tertiary care center. Subjects and Methods. Thirty-two patients with laryngeal squamous cell carcinoma, previously untreated, who underwent SCPL with cricohyoidopexy or cricohyoidoepiglottopexy were reviewed. Results. At 1, 3, and 5 years, the disease-free survival rates were 96.9%, 89.4%, and 78.2%; overall survival rates were 96.9%, 93.2%, and 87.3%; local control and locoregional control rates were 100%, 96.2%, and 96.2%; and distant metastasis-free survival rates were 100%, 100%, and 88.2%, respectively. Aspiration pneumonia was the most common complication observed. The 3 laryngeal functions (speech, swallowing, and breathing) were spared in 83.9% of patients. Conclusion. Supracricoid partial laryngectomy for selected glottic and supraglottic T3 tumors has excellent oncologic and functional results
