The RLN is capable of regeneration, but laryngeal functions in cases of severe injury remain impaired. This permanent impairment is caused by either incomplete regeneration and/or occurrence of laryngeal synkinesis. Laryngeal reinnervation can be approached either nonselectively, focusing on nerve reconstruction, or selectively, focusing on separate target muscle reinnervation. Nonselective reinnervation comprises anastomosis to the mainstem of the RLN leading to reinnervation of both abductor and adductor muscle groups (nerve-based reconstruction). In selective reinnervation, abductor and/or adductor muscles are separately reinnervated (function-based reconstruction). A review of laryngeal reinnervation techniques, results in animal models, and the results achieved in patients are given. The clinical implications of reinnervation in unilateral as opposed to bilateral vocal fold paralysis are considered. For unilateral vocal fold paralysis and nonselective reinnervation, good voice results can be achieved. It has the advantage that no foreign materials need to be implanted and may also be used in a growing larynx in the case of children or adolescents. For bilateral vocal fold paralysis, good functional results, recovery of airway as well as voice, can be achieved with selective (or function-based) reinnervation.</p>","PeriodicalId":39848,"journal":{"name":"Advances in Oto-Rhino-Laryngology","volume":"85 ","pages":"98-111"},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"38582239","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Natural History of Treated and Untreated Hypopharyngeal Cancer.","authors":"Hans E Eckel,&nbsp;Patrick J Bradley","doi":"10.1159/000492305","DOIUrl":"https://doi.org/10.1159/000492305","url":null,"abstract":"<p><p>Patients with hypopharyngeal cancers frequently present at advanced stage and in poor general health status. Their natural history is characterised by diffuse local primary disease, mucosal and submucosal spread, early cervical nodal metastasis, and a relatively high rate of distant spread. By the time of initial diagnosis, some 60% of all hypopharyngeal cancer patients will be with stage IV disease, some 5% will present with distant metastases, and almost 40% will have a significant reduction in performance status. Less than 20% are diagnosed with a localised early stage disease. A long-standing social habit of excess of alcohol and tobacco usage leads to cancerisation and accounts for the multiple, synchronous primary malignant lesions that occur in many hypopharyngeal cancer patients. The natural history of untreated head and neck squamous cell carcinoma has infrequently been documented in the medical literature. However, without understanding the natural history of hypopharyngeal cancer, patient counselling and clinical management are difficult. Less than 20% of untreated patients survive for > 12 months and only a small proportion of patients will survive for more than 2 years after initial diagnosis. The natural course of the disease in patients treated for cure or, at least, for the relief of symptoms, is certainly more favourable than that of those who are not suited for, or not willing to accept the adverse effects of treatment. However, treatment results are still considerably less encouraging than those that are being reported for other sub-sites of the head and neck region. Among all head and neck cancer sites, 5-year age-standardised relative survival is currently the poorest for cancer of the hypopharynx and the highest for larynx cancers, 25 and 59%, respectively. Among the head and neck cancers, only hypopharynx showed a low outcome (25% at 5 years), with survival figures ranging between ≤30 (North Ireland and Italy) and 8% (Bulgaria). Recent studies from the United States indicate that overall 5-year survival rates for hypopharyngeal cancer have improved significantly in recent years, with the average survival being ≥40%.</p>","PeriodicalId":39848,"journal":{"name":"Advances in Oto-Rhino-Laryngology","volume":"83 ","pages":"27-34"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000492305","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37117093","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, dizziness and imbalance are common in the elderly and have substantial impact on the quality of life. Dizziness interferes with the everyday activities of 30% of persons over age 70. As causes can be multiple, including vestibular and non-vestibular components, it is crucial to detect the factors leading to dizziness and imbalance to maintain mobility and avoid secondary complications like falls and anxiety. The more common causes of dizziness and imbalance in old age are sensory deficits, such as bilateral vestibular hypofunction, polyneuropathy, and impaired visual acuity; benign paroxysmal positional vertigo; and central disorders such as cerebellar ataxia and normal-pressure hydrocephalus. Further relevant factors include sedative or antihypertensive medication, loss of muscle mass (sarcopenia), and the fear of falling. Many elderly persons have multiple risk factors at the same time. Treatable components include benign paroxysmal positional vertigo that can be effectively treated with specific physical maneuvers, sedating drugs that can be reduced in many cases, and sarcopenia that can be treated with physical training. If a specific cause for dizziness and imbalance can be identified, treatment is often successful even in advanced age. The common causes can be revealed by systematic clinical examination and selective laboratory testing.","PeriodicalId":39848,"journal":{"name":"Advances in Oto-Rhino-Laryngology","volume":"82 ","pages":"143-149"},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1159/000490283","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37119747","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The utility of the monothermal caloric screen has been proposed in various studies. When appropriate cut-offs are used, the monothermal screen can be completed with a low false-negative rate. Air is often used as a medium for caloric testing, though not without some controversy. When air and water are compared, the response magnitudes for air are consistently smaller than for water.

Close follow-up is crucial in achieving early detection and being able to treat the recurrence with curative intention. When persistent or recurrent disease is suspected, cross-sectional computed tomography imaging (CT) and positron emission tomography-CT scanning followed by panendoscopy with biopsies are the initial steps that need to be done in order to confirm diagnosis and accurate staging. The current treatment modality, which results in the best survival outcomes for rHCP is surgery. For most suitable patients, total pharyngolaryngectmy remains the best surgical modality, although open partial surgery OPS and transoral surgery are options for a small number of patients who have recurrences following treatment of an early stage disease. Free tissue transfer flaps or pedicled myocutaneous flaps will be necessary for most patients to reconstruct the excised pharynx.
