The effect of tracheostomy on swallowing function in open partial horizontal laryngectomies: preliminary experience.

OBJECTIVE: Tracheostomy is required to ensure a safe airway in open partial horizontal laryngectomies. The presence of the tracheostomy tube can contribute to post-operative dysphagia. This study aimed to evaluate the effects of a circumferential tracheostomy technique on swallowing. METHODS: A retrospective study was conducted of patients who underwent open partial horizontal laryngectomies between April 2018 and June 2019. Patients were divided into two groups based on the tracheostomy technique: group 1 had two stitches from the inferior tracheal ring to the skin; group 2 had circumferential fixation of the trachea to the skin. Demographic information, surgical data, post-operative rehabilitation course and complication details were collected and analysed. RESULTS: Twenty-four patients were enrolled. Patients in group 2 had significant improvement in the initial phases of swallowing rehabilitation. CONCLUSION: Tracheostomy with anchorage of the trachea to the skin by circumferential stitches could allow early removal of the tracheal tube, with a better swallowing outcome.

Quality of life in vestibular schwannoma: a comparison of three surgical techniques.

OBJECTIVE: Through years, interest in quality of life (QoL) among patients affected by vestibular schwannoma (VS) has increased. The expansion of the indications for endoscopic ear surgery allowed the development of the transcanal transpromontorial surgery (TTS) for VS removal. The objective of the present study was to assess QoL in a cohort of VS patients operated on by translabyrinthine (TL), retrosigmoid (RS) and TTS approach. METHODS: The study was conducted on 111 patients who underwent surgery for VS between January 2017 and January 2020 at two different institutions. Patients fulfilled three questionnaires during follow-up: Glasgow Benefit Inventory, Depression Anxiety Stress Scales-21 and Penn Acoustic Neuroma Quality-Of-Life. The association between sex, age, date of surgery, tumor size, post-operative facial nerve (FN) function and QoL outcomes was assessed. RESULTS: An overall subjective impairment was demonstrated in all groups. Age, Koos staging and FN functions were associated to distinct QoL outcomes. CONCLUSIONS: QoL decreases in patients surgically treated for VS. The TTS may allow improved scores in many domains, confirming to be a subjectively well-tolerated technique.

Delayed recovery from severe acute respiratory syndrome coronavirus-2 related anosmia predicts incomplete olfactory restoration.

OBJECTIVE: This study aimed to assess the olfactory recovery rates and patterns in a cohort of coronavirus disease 2019 positive patients, and to investigate the clinical predictors of poor long-term olfactory restoration. METHODS: An observational retrospective study was conducted on 146 patients between September 2020 and January 2021 at a tertiary referral hospital. Coronavirus disease 2019 positive patients with olfactory dysfunction were sent a modified version of the COVID-19 Anosmia Reporting Tool for Clinicians via e-mail. RESULTS: The difference in median recovery time between complete recovery and incomplete or no recovery was statistically significant. On multivariate analysis, the only significant factor associated with incomplete or no recovery was anosmia duration. CONCLUSION: After a mean time of 5.6 months from severe acute respiratory syndrome coronavirus-2 infection, persistent olfactory disorders were self-reported in 36.7 per cent of patients. Complete recovery was more likely to occur within 15 days. Given the high prevalence of coronavirus disease 2019, a large number of patients are expected to suffer from long-term olfactory morbidity.

Emerging and re-emerging infectious disease in otorhinolaryngology.

SUMMARY: Emerging and re-emerging infectious disease in otorhinolaryngology (ENT) are an area of growing epidemiological and clinical interest. The aim of this section is to comprehensively report on the epidemiology of key infectious disease in otorhinolaryngology, reporting on their burden at the national and international level, expanding of the need of promoting and implementing preventive interventions, and the rationale of applying evidence-based, effective and cost- effective diagnostic, curative and preventive approaches. In particular, we focus on i) ENT viral infections (HIV, Epstein-Barr virus, Human Papilloma virus), retrieving the available evidence on their oncogenic potential; ii) typical and atypical mycobacteria infections; iii) non-specific granulomatous lymphadenopathy; iv) emerging paediatric ENT infectious diseases and the prevention of their complications; v) the growing burden of antimicrobial resistance in ENT and the strategies for its control in different clinical settings. We conclude by outlining knowledge gaps and action needed in ENT infectious diseases research and clinical practice and we make references to economic analysis in the field of ENT infectious diseases prevention and care.

Eagle's Syndrome, from clinical presentation to diagnosis and surgical treatment: a case report.

SUMMARY: Eagle's syndrome is a condition associated with the elongation of the styloid process or calcification of the stylohyoid ligament, clinically characterised by throat and neck pain, radiating into the ear. In this report, we describe the case of a 60-year-old woman who presented with a severe unilateral trigeminal and glossopharyngeal neuralgia. The patient was subjected to conservative therapy for four months and did not report improvement of the symptoms. After several consultations with different physicians, a diagnosis was accomplished by radiological investigation (multidetector computer tomography with multi-planar reconstructions and 3D volumetric reconstructions). Surgical styloidectomy was performed, with subsequent sudden remission of symptoms. Eagle's syndrome represents a commonly unrecognised nosological entity, clinically characterised by non-specific cranio-facial pain. Differential diagnosis includes glossopharyngeal and trigeminal neuralgia, temporal arteritis, migraine, myofascial pain dysfunction and cervical arthritis. Eagle's syndrome should always be suspected, mostly in adult women when the pain is unilateral and not responsive to painkillers.

Biofilm in voice prosthesis: A prospective cohort study and laboratory tests using sonication and SEM analysis.

OBJECTIVE: The objective of the study was to compare the biofilm growing pattern and its morphological extent on silicone and a teflon-like material using a sonication process and a Scanning Electron Microscope (SEM). DESIGN: A prospective cohort study and a laboratory study. SETTING: Otolaryngology -Head and Neck surgery Department and the Microbiology Institute. PARTICIPANTS: The participants included fifteen laryngectomised patients with phonatory prostheses, which were removed because of device failure, and two different kinds of phonatory prostheses from the laboratory (Provox 2 and ActiValve) that were artificially colonised by Candida albicans. MAIN OUTCOME MEASURES: Tracheo-oesophageal puncture (TEP) is currently considered the gold standard for post-laryngectomy voice rehabilitation. "Leakage" represents the most common cause of substitution and is generated by biofilm colonisation of the prosthesis by mixed mycotic and bacterial agents. New biomaterials have been developed that are deemed to be more resistant to the colonisation of micro-organisms and material deformation. RESULTS: The devices showed colonisation by mixed bacterial flora (Staphylococci 13%, Streptococci 9%, and Haemophilus influenzae 5%) and by yeasts (Candida albicans 12%). Moreover, we observed a different distribution of biofilm layers in Provox ActiValve (22.56%) compared to Provox 2 (56.82%) after experimental colonisation by the previously isolated Candida strain. CONCLUSION: Resident microbiological species from the upper airways unavoidably colonise the polymer surfaces, and no strategies have been effective except for the manipulation of the chemical-physical properties of the device's polymer. Our study confirms that Provox ActiValve, which is made with a fluoroplastic material (teflon-like), is less subject to in vitro colonisation by Candida, and thus showed a higher clinical resistance to biofilm and a longer lifespan. The sonication seems to significantly improve the knowledge of bacterial and mycotic flora in biofilm colonisation. The design of a device for the daily cleaning capable to reach and brush the oesophageal flange of the prosthesis preserving the valve mechanism could represent a practical and simple help in this still unsolved problem.

Facial pain: sinus or not?

Facial pain remains a diagnostic and therapeutic challenge for both clinicians and patients. In clinical practice, patients suffering from facial pain generally undergo multiple repeated consultations with different specialists and receive various treatments, including surgery. Many patients, as well as their primary care physicians, mistakenly attribute their pain as being due to rhinosinusitis when this is not the case. It is important to exclude non-sinus-related causes of facial pain before considering sinus surgery to avoid inappropriate treatment. Unfortunately, a significant proportion of patients have persistent facial pain after endoscopic sinus surgery (ESS) due to erroneous considerations on aetiology of facial pain by physicians. It should be taken into account that neurological and sinus diseases may share overlapping symptoms, but they frequently co-exist as comorbidities. The aim of this review was to clarify the diagnostic criteria of facial pain in order to improve discrimination between sinogenic and non-sinogenic facial pain and provide some clinical and diagnostic criteria that may help clinicians in addressing differential diagnosis.

Idiopathic SIADH in young patients: don't forget the nose.

Olfactory neuroblastoma (ONB) is an uncommon neuroendocrine sinonasal cancer associated by many authors to ectopic production of several biologically active substances. We report a case of a 31-year-old male patient who presented with idiopathic syndrome of inappropriate secretion of antidiuretic hormone (SIADH). During diagnostic work-up, a CT scan of the head was performed and an ethmoidal ONB was detected. Endoscopical surgery followed by radiotherapy was carried out. Immediately after surgery natraemia levels normalised. Five years later the patient is disease-free. To our knowledge, 17 cases of SIADH associated to ONB have been published. In nine reports, idiopathic SIADH promptly led to the diagnosis of the sinonasal mass as in our clinical case, however, in many reports, correct diagnosis was accomplished months to years later. In young patients with idiopathic inappropriate antidiuretic hormone secretion, a neuroendocrine malignancy of the sinonasal area must be excluded.

Tensor veli palatini electromyography for monitoring Eustachian tube rehabilitation in otitis media.

BACKGROUND: The pathogenesis of otitis media is related to Eustachian tube dysfunction. The tensor veli palatini muscle actively opens the Eustachian tube and promotes middle-ear ventilation. This study describes a technique for paratubal electromyography that uses a surface, non-invasive electrode able to record tensor veli palatini muscle activity during swallowing. METHODS: Twenty otitis media patients and 10 healthy patients underwent tensor veli palatini electromyography. Activity of this muscle before and after Eustachian tube rehabilitation was also assessed. RESULTS: In 78.5 per cent of patients, the electromyography duration phase and/or amplitude were reduced in the affected side. The muscle action potential was impaired in all patients who underwent Eustachian tube rehabilitation. CONCLUSION: This study confirmed that Eustachian tube muscle dysfunction has a role in otitis media pathogenesis and showed that muscle activity increases after Eustachian tube rehabilitation therapy.

Audiological Monitoring in Children Treated with Platinum Chemotherapy.

Platinum compounds constitute the standard treatment for solid tumors in pediatric oncology. The purpose of this study is to assess the impact of platinum compounds in the development of ototoxicity in children following chemotherapy. This study included 160 patients treated with cisplatin and carboplatin for malignant solid diseases from 2007 to 2014. Their audiograms were classified according to the Boston SIOP ototoxicity scale. Twenty-five percent of the children treated with platinum compounds developed ototoxicity. The incidence of ototoxicity was correlated with the type of platinum derivative (i.e. cisplatin vs. carboplatin), coadministration of both drugs and concomitant cranial radiotherapy, but not with sex and age. Cumulative dose was correlated only with the cisplatin administration. Nine patients (8.6%) showed further progression of hearing impairment after the end of chemotherapy. The low rate of ototoxicity suggests the pivotal role of auditory monitoring in children treated with platinum compounds in order to be able to identify hearing loss at an early stage and to provide, jointly with pediatric oncologists, strategies to reduce further progression of cochlear toxicity.

Comorbidities and recurrence of benign paroxysmal positional vertigo: personal experience.

OBJECTIVE: The aim of this study is to evaluate the correlation between clinical features of benign paroxysmal positional vertigo (BPPV) and age, sex, trauma, presence of one or more comorbidities such as cardiovascular, neurological, endocrinological, metabolic, psychiatric diseases. DESIGN: Retrospective review of medical records (chart review). STUDY SAMPLE: A total of 475 patients aged from 14 to 87 years, affected by BPPV. RESULTS: Recurrence of BPPV occurred in 139/475 patients (29.2%). The recurrence rate was significantly higher in female and older patients. Comorbidities were present in 72.6% of subjects with recurrent BPPV vs. 48.9% of patients with no recurrence (p < 0.01). Forty-two patients (8.8%) reported a cranial trauma as a triggering event. Post-traumatic patients showed a significantly higher persistence rate (45.2%) compared to patients affected by non-traumatic BPPV (20.5%). Recurrence rates are overlapping between the two groups. CONCLUSION: Our results confirm the association between recurrence of BPPV and age, female sex, and presence of comorbidities. The correlation is stronger in patients affected by multiple associated diseases; the most frequently involved pathologies are psychiatric disorders, followed by neurological and vascular diseases. Collecting a complete medical history is important for prognostic stratification and detection of potential underlying pathological conditions.

Minimally invasive surgical removal of an intracochlear schwannoma causing an intractable paroxysmal positional vertigo.

Intracochlear schwannomas are rare tumours. Diagnosis is based on high-resolution MRI, which should be used for accurate determination of the location of tumours. We report a case of a cochlear schwannoma that presented with profound hearing loss and intractable paroxysmal positional vertigo, which was diagnosed with gadolinium-enhanced MRI and removed using a transcanal minimally-invasive transotic approach.

Death due to crush injuries in a compactor truck: vitality assessment by immunohistochemistry.

We present a case in which the timing of injuries was requested to determine whether the death of a man found in a landfill was due to homicide or accident. The use of immunohistochemistry to detect P-selectin and E-selectin on endothelial cells of vessels in damaged skin samples, and compare them with intact skin samples, as well as the presence of lung adipose embolism provide information on the timing of the injury, thereby helping substantially to identify the dynamics of death.
