Objective Thyroid surgery may lead to postoperative complications. The aim of this paper was to determine whether the rate of postoperative hypoparathyroidism (HPT) is influenced by whether surgery is staged. Design Single-institution retrospective observational study. Methods The clinical records of 786 patients treated at the Otolaryngology Unit of the Azienda USL-IRCCS di Reggio Emilia between January 1990 and December 2015 were reviewed. Patients were divided into two groups according to the surgical treatment received: group TT (637 patients, 81.04%) underwent single-stage total thyroidectomy; Group cT (149 patients, 18.96%) underwent loboisthmusectomy and delayed completion total thyroidectomy. Transient and permanent HPT, assessed after 6 months of follow-up, were the primary endpoints. Risk factors of postoperative HPT were also analysed as secondary outcomes. Results Rates of transient HPT in group TT were higher than those observed in group cT, (P = 0.0057). Analysis of risk factors identified sex as an independent risk factor for transient HPT only for group TT (P = 0.0012) and the number of parathyroid glands remaining in situ (PGRIS) as an independent risk factor for transient and permanent HPT for group TT (P < 0.0001 and P = 0.0002, respectively). Conclusions This study suggests that the risk of transient postoperative HPT is lower in patients that undergo completion thyroidectomy. Further independent risk factors for postoperative HPT are female sex and PGRIS score. In light of the growing use of conservative surgery for thyroid neoplasms, these findings could help to adequately plan surgery in order to reduce endocrine complications.

Objective: To assess all different patterns of associated abnormalities on audiometry, bithermal caloric test (BCT) and cervical/ocular vestibular-evoked myogenic potentials (VEMPs) to air/bone-conduction in patients with selective posterior semicircular canal (PSC) hypofunction and to correlate them with underlying disorders. Study Design: Retrospective review. Setting: Tertiary referral center. Patients: 51 patients (23 men, 28 women, mean age 57.5 yr) with isolated PSC deficit (one bilateral). Interventions: Correlation with instrumental data and underlying diagnoses. Main Outcome Measures: Video-oculographic findings, objective measurements on audiometry, BCT, VEMPs and video-head impulse test (vHIT). Results: Ongoing or previous acute vestibular loss (AVL) was diagnosed in 13 patients (25.5%, 3 inferior vestibular neuritis, 10 AVL with sudden sensorineural hearing loss [SSNHL]), Meniere's disease (MD) in 12 (23.5%), cerebellopontine angle (CPA) lesion in 9 (17.6%), various causes in 7 (13.7%), benign paroxysmal positional vertigo (BPPV) involving the non-ampullary arm of PSC in 5 cases (9.8%) whereas unknown pathology in 5 (9.8%). Involvement of at least one additional receptor besides PSC was seen in 89.8% of cases. Cochlear involvement was diagnosed in 74.5% with pure-tone average significantly greater in patients with AVL+SSNHL (p < 0.05). Overall involvement of labyrinthine receptors or afferents was highest in patients with AVL+SSNHL (p < 0.01), MD and CPA lesions (p < 0.05). Conclusions: Isolated loss of PSC function on vHIT is mostly accompanied by additional labyrinthine deficits that could only be identified through an accurate instrumental evaluation. Assessment of all receptors and afferents should be always pursued to identify the lesion site and better understand the underlying pathophysiological mechanisms.

Objective Though fluctuations in vestibular function represent a common finding in Meniere's disease, we describe how benign paroxysmal positional vertigo (BPPV) may result in fluctuations of vestibulo-ocular reflex for the involved canal depending on the disposition of otoliths. Patient A 54-year-old woman suffering from refractory posterior canal (PC)-BPPV resulting in fluctuating PC function. Interventions Diagnostic evaluation and rehabilitative treatment for BPPV involving the affected PC. Main outcome measures Video-Frenzel and video-head impulse test (vHIT) findings before and after canalith repositioning procedures for PC-BPPV. Results BPPV involving the nonampullary arm of right PC was diagnosed based on presenting positional downbeat nystagmus and selective right PC hypofunction at the vHIT. During physical treatment, nystagmus first became positional paroxysmal upbeat likely due to a shift of debris into the ampullary arm of the canal, then turned to spontaneous downbeat nystagmus consistently with a plug effect exerted by particles entrapped within the nonampullary arm of PC and finally receded proving an otoliths fall within the utriculus. Simultaneously, vHIT documented fluctuations for right PC vestibulo-ocular reflex gain as it first increased to normal values, then severely declined and finally normalized, respectively. High-resolution computed tomography scan detected ipsilateral superior canal dehiscence. Conclusions In accordance with recently reported vHIT findings in different types of BPPV, fluctuation of PC function could be likely explained by the effect of particles on cupular dynamic responses depending on the portion of the canal gradually involved. Superior canal dehiscence may have played a role facilitating otoliths mobilization by reducing labyrinthine impedance.

Objective Patients with acute respiratory failure due to COVID-19 have a high likelihood of needing prolonged intubation and may subsequently require tracheotomy. Usually, the choice of technique (percutaneous dilatational tracheotomy [PDT] versus open surgical tracheotomy [OST]) depends on the preference of surgeons and patient-related factors. In case of COVID-19, airborne spread of viral particles and limited time of apnea must be considered in the choice of the safest technique. The aim of this study is to compare the complication rates and offer an assessment of relative risks and benefits of PDT versus OST in patients with severe COVID-19. Methods We performed a retrospective study considering 47 consecutive patients affected by severe acute respiratory distress syndrome due to SARS-CoV-2 infection, needing invasive mechanical ventilation and subsequent tracheostomy. This study was performed at the Intensive Care Unit of our tertiary referral center. Complication rates were analyzed. Results Seventeen patients underwent PDT and 30 patients were submitted to OST. Twenty-six patients (55.3%) had post-operative complications (local infection, hemorrhage, subcutaneous emphysema) with no significant difference between PDT and OST. Conclusion PDT and OST are characterized by similar postoperative complication rates in severe COVID-19 patients. These findings suggest that OST might be preferred if expert ENT surgeons are available, as PDT could result in longer apnea and exposure to generated aerosol. However, authors recommend considering either OST or PDT at the discretion of the medical staff involved, according to the personal experience of the operators performing the procedure.

Objective Restriction in healthcare services during the COVID-19 pandemic caused delays in the diagnosis and treatment of several diseases. To overcome the risk of missed diagnosis of head and neck cancers, before deleting the scheduled appointments, we have introduced a selection of the patients by examining the clinical presenting issue and previous medical history. The aim of this study is to show the effects of the abovementioned strategy on the diagnosis and management of laryngeal cancer. Methods Data were extracted from the Hospital software regarding the new diagnosis of laryngeal SCC in the periods from March 2020 to December 2020 during the pandemic (study group) and from March 2019 to December 2019 (control group) were collected. Data were compared regarding: TNM stage, time from first medical examination to histological diagnosis (Time-1), and time form histological diagnosis to beginning of treatments (Time-2). Results The final study group was composed by 19 laryngeal cancers, the control group by 25 cases. No significant differences were found in the tumour stage between the groups. In the study group, Time-1 was shorter (24 days versus 43 days, p = 0.012), while Time-2 in surgically-treated patients was longer (20 days versus 9 days, p = 0.012). Conclusion During the pandemic, there was a dramatic lack of medical and nurse staff needed for surgical procedures. As consequence, the time between the diagnosis of malignancy and surgical treatment increased. In our unit, an efficient patient selection strategy to reschedule medical appointments avoided a dangerous shift toward higher laryngeal cancer stages.

NUT carcinoma (NUT-C) is a relatively new malignancy that was recently listed in the 4th edition of the WHO Classification of Head and Neck Tumors in 2017. NUT carcinoma is a rare, aggressive, poorly differentiated carcinoma genetically defined by chromosomal rearrangement of the nuclear protein in testis (NUTM1) gene. The prognosis is extremely poor, with a mean survival

Objectives: Patients with acute respiratory failure due to coronavirus disease 2019 (COVID-19) have a high likelihood of needing prolonged intubation and may subsequently require tracheotomy. Indications and timing for performing tracheotomy in patients affected by severe COVID-19 pneumonia are still elusive. The aim of this study is to analyze the role of tracheotomy in the context of this pandemic. Moreover, we report the timing of the procedure and the time needed to complete weaning and decannulation in our center. Methods: This retrospective, observational cohort study included adults (≥18 years) with severe COVID-19 pneumonia who were admitted to the intensive care unit (ICU) of the tertiary care center of Reggio Emilia (Italy). All patients underwent orotracheal intubation with invasive mechanical ventilation, followed by percutaneous or open surgical tracheotomy. Indications, timing of the procedure, and time needed to complete weaning and decannulation were reported. Results: Forty-four patients were included in the analysis. Median time from orotracheal intubation to surgery was 7 (range 2-17) days. Fifteen (34.1%) patients died during the follow-up period (median 22 days, range 8-68) after the intubation. Weaning from the ventilator was first attempted on median 25th day (range 13-43) from orotracheal intubation. A median of 35 (range 18-79) days was required to complete weaning. Median duration of ICU stay was 22 (range 10-67) days. Mean decannulation time was 36 (range 10-77) days from surgery. Conclusions: Since it is not possible to establish an optimal timing for performing tracheotomy, decision-making should be made on case-by-case basis. It should be adapted to the context of the pandemic, taking into account the availability of intensive care resources, potential risks for health care workers, and benefits for the individual patient.

Objective To describe a rare case of pneumolabyrinth (PNL) and pneumocephalus (PNC) due to otogenic meningitis in a patient with superior canal dehiscence (SCD) resulting in profound sensorineural hearing loss (SNHL), semicircular canals impairment but preservation of SCD-related enhanced otolith function. Patient A 65-year-old woman with otogenic meningitis. Intervention Temporal bone high-resolution computed tomography (CT) scans, brain-magnetic resonance imaging, audiometry, bedside examination, video-head impulse test, and vestibular-evoked myogenic potentials (VEMPs). Main outcome measures Enhanced otolith function despite canal and cochlear loss. Results The patient developed right profound SNHL and acute labyrinthitis. Imaging showed middle ear inflammatory tissue, right PNL and PNC despite lack of bony fractures. Bilateral SCD and tegmen dehiscence were detected. The patient underwent mastoidectomy, drainage of effusion, and surgical repair of tegmen dehiscence. Exploratory tympanotomy was uneventful. She was treated with intravenous antibiotics and dexamethasone for 3 weeks with improvement of general condition. At 3-weeks follow-up, right profound SNHL persisted with global hypofunction for ipsilateral semicircular canals and selective impairment for left superior canal activity at video-head impulse test. Surprisingly, both cervical and ocular-VEMPs exhibited bilaterally abnormal amplitudes and reduced thresholds, consistently with preserved SCD-related macular hypersensitivity to sounds even on the affected side. Conclusions This case report exhibits a unique clinical scenario as it offers interesting insights concerning PNL aetiology despite lack of either bony fractures or barotrauma and PNC likely conveyed intracranially by SCD. Moreover, it provides an unusual pattern of functional dissociation among inner-ear receptors showing enhanced otolith function despite severe labyrinthine damage.

Congenital nasal pyriform aperture stenosis (CNPAS) is a rare anomaly causing respiratory distress in newborns. While the primary surgical technique is well established, the timing of the removal of the stents and the management of restenosis remain a matter of debate. We report a case of a female newborn affected by CNPAS with the recurrence of respiratory distress after primary surgery due to the early removal of nasal stents, causing an overgrowth of granulation tissue. This report notes that restenosis was successfully managed by repeating the procedure over a 14-day period, with soft polyvinyl chloride uncuffed tracheal tubes acting as nasal stents.

Patients affected by severe acute respiratory syndrome coronavirus 2 disease (COVID-19) with respiratory distress may need invasive mechanical ventilation for a long period of time. Head and neck surgeons are becoming increasingly involved in the care of COVID-19 patients because of the rapidly increasing number of tracheotomies required. This procedure, when performed without protection, may lead to the infection of the medical and nursing staff caring for the patient. The aim of this report is to share our protocol for performing a safe surgical tracheotomy in COVID-19 patients. Infection of the nursing/medical staff involved in the first 30 tracheotomies performed in patients affected by COVID-19 in the Intensive Care Unit of a tertiary referral center were evaluated. Mistakes that occurred during surgery were analyzed and discussed. None of the nursing/medical staff presented signs or symptoms of COVID-19 within 15 days after the procedure. Conclusion: The authors have prepared a protocol for performing a safe surgical tracheotomy in patients affected by COVID-19. Surgeons who might be involved in performing the tracheotomies should become familiar with these guidelines.

Purpose: To investigate and compare the effect of endoscopic and microscopic type 1 tympanoplasty on the cochlear function, to determine if they have a different impact on the inner ear function. Methods: 72 ears treated by transcanal endoscopic type 1 tympanoplasty and 84 ears treated by microscopic type 1 tympanoplasty in 3 tertiary referral centers were enrolled in the study. Microscopic type 1 tympanoplasty were performed by transcanal or retroauricular approach. Only patients with mobile and intact ossicular chain were involved in the study. A retrospective chart review was performed. Main outcome measures were: (1) change in bone conduction thresholds at 250, 500, 1000, 2000, 4000Hz; (2) change in bone conduction Pure Tone Audiometry; (3) correlation of audiometric outcomes with surgical technique, graft type and graft position. Results: A mild postoperative bone conduction threshold shift was observed at 2000Hz and 4000Hz in both groups, without significant differences between the two groups. No statistically significant modifications in bone conduction were observed at any frequencies in patients operated by transcanal endoscopic approach compared with those who underwent transcanal or retroauricular microscopic type 1 tympanoplasty. Moreover, neither the placement nor the type of the graft seemed to influence the cochlear function preservation. Conclusions: The endoscopic and the microscopic approaches have a similar impact on the bone conduction threshold during type 1 tympanoplasty. In particular, the one-handed manipulation of the ossicular chain during the endoscopic technique did not show an increased risk of inner ear damage.

Objectives To describe a unique case of acute vertigo presenting with spontaneous horizontal nystagmus (SHN) and a clinical picture consistent with right acute peripheral vestibular loss (APVL) in which an isolated hypofunction of a horizontal semicircular canal (HSC) permitted to detect a spontaneous canalith jam and treat the patient accordingly. Methods Case report and literature review. Results A 74-year old woman presented with acute vertigo, left-beating SHN and a clinical picture consistent with right APVL. Nevertheless, vestibular evoked myogenic potentials were normal with symmetrical amplitudes and the video head impulse test (vHIT) revealed an isolated hypofunction of the right HSC. After repeated head shakings, the supine roll test evoked bilaterally a positioning paroxysmal geotropic horizontal nystagmus suggesting benign paroxysmal positional vertigo involving the non-ampullated arm of the right HSC. vHIT and caloric testing confirmed restitution of HSC function after repositioning maneuvers. Conclusions In case of acute vertigo with SHN, a complete functional assessment of vestibular receptors and afferents should always be given in order to avoid misdiagnosis. Canalith jam should be considered in case of spontaneous nystagmus and isolated canal hypofunction.

Background. The purpose of this study was to assess the factors influencing swallowing and phonatory results after partial laryngectomy. Methods. We carried out a medical chart review of patients who underwent partial laryngectomies between June 2003 and November 2010, focusing on functional outcomes. Results. Thirty-two patients were enrolled. No statistically significant difference was found in the comparison of phonatory outcomes of patients with preservation of both arytenoids; the results of the Yanagihara classification were significantly different (p ¼ .015) in patients with an atypical neoglottis; radiotherapy statistically significantly influenced only the mean fundamental frequency (p ¼ .035). The type of partial laryngectomy does not seem to affect the deglutition results; radiotherapy statistically significantly affected the dysphagia score (DS; p ¼ .03), penetration aspiration (p ¼ .02), and MD Anderson Dysphagia Inventory (MDADI; p ¼ .02). Conclusion. Horizontal supraglottic laryngectomy and supracricoid partial laryngectomy give the same swallowing results. The presence of both arytenoids does not influence the final outcome compared to patients in whom only 1 arytenoid is preserved. Postoperative radiotherapy only influences the swallowing function.

The objective of this study was to analyze atypical neoglottis after supracricoid subtotal laryngectomy (SSL) from a morphological and functional point-of-view using retrospective case series reviewin a Tertiary university referral center setting. From May 2003 until January 2010, 106 patients underwent SSL (CHEP, CHP, THEP, THP) for laryngeal cancer, in the Otolaryngology Department of the University Hospital of Modena. We performed a retrospective analysis of recorded videos in our database of patients who underwent SSL. Patients with atypical neoglottis were included in the study. Six patients with atypical neoglottis were identified and morphologically evaluated. The functional outcomes were collected and analyzed. Atypical neoglottis may form after SSL, in particular in the case of CHEP. In most cases, these atypical conformations are due to anomalous positioning of the epiglottis, or involvement of the lateral pharyngeal wall in the sphincteric and vibratory function of the neoglottis. Atypical neoglottis formation seems to guarantee adequate functional outcomes in terms of vocal and swallowing performance. © 2011 Springer-Verlag.

Objective: We evaluated the efficacy of voice therapy according to Borragan's method associated to S. Magnani's vocal counselling in functional dysphonia in children. Patients and methods: We prospectively treated 16 patients with vocal fold nodules (10 males, 6 females). Age ranged from 6 to 11 years with a mean age of 9 years. We performed a full screening phoniatric evaluation. In addition psychological tests were carried out to investigate psychological background. Results: We lost three patients at follow-up; one patient received surgery, eight patients healed (43.75%), four improved (25%). There was no statistical difference in the analysis of electroacoustical parameters while MPT significatively raised after therapy. Conclusion: If patients have motivation voice therapy could improve functional dysphonia in children. It is also important psychological background. Further studies on bigger populations with long-term follow-up are needed. © 2006 Elsevier Ireland Ltd. All rights reserved.

Objectives: To describe the magnetic resonance (MR) appearance of polydimethylsiloxane (PDMS) injections in the head and neck region. Study design: Retrospective review of MR images from a case series. Methods: MR images of 10 patients, who underwent PDMS injections at our department, were reviewed. Data from imaging were collected and analyzed. Results: After injection, PDMS can be identified in MR images, particularly in T2-weighted images in the early stages. Its MR characteristics are similar to silicone in other regions, but with time, its appearance can change. Conclusions: The integration of PDMS with tissues may also be reflected in changes in MR appearance, as a result of an increased amount of fibrous tissue in the region injected. Radiologists and ENT specialists may benefit from knowledge of the MR characteristics and variability in appearance of PDMS in human tissues for improving image interpretation. © 2010 Elsevier Ireland Ltd.

Parapharyngeal space (PPS) tumors are rare and benign in 80% of cases. Since surgeons first resected this anatomical region, the surgical approach to PPS bulks has been a hot topic due to their shape and the important structures involved. We present a series of patients treated with a transcervical or transcervical-transparotid approach to benign PPS tumors without mandibulotomy. Between May 2003 and March 2009, 18 patients (11 male and 7 female) with benign PPS tumors underwent a surgical resection, avoiding mandibulotomy. Average age of the patients was 49 years (range 3-76), average tumor size was 5.5 × 4 × 3 cm and histological examination of the resected tumors showed: seven pleomorphic adenomas of the deep parotid lobe, four schwannomas, two mycobacteriosis, two paragangliomas of the vagus nerve, one lipoma, one neurofibroma and one cavernous hemangioma. Seven patients underwent a transcervical approach, while 11 patients underwent a transcervical-transparotid approach. Excision of benign PPS tumors is possible without mandibulotomy even in the case of a large tumor mass, but exposure with the mandible in situ is certainly poor. Avoiding mandibulotomy reduces patient morbidity and hospital stay. In our experience, mandibulotomy can be avoided in most cases of benign PPS tumors leaving this procedure for malignant tumors or in patients with very poor exposure. © 2011 Springer-Verlag.

Objectives: To evaluate the clinical performance of an auto-crosslinked gel obtained from hyaluronic acid (ACP-based gel) as an anti-adhesive agent and/or augmentative agent in vocal cord surgery for the treatment of vocal fold (VF) atrophy, sulcus vocalis, and postsurgery scarring as well as its tolerability at short- and long-term follow-up. Study Design: This was a prospective multicenter trial conducted between 2007 and 2009. Setting: Academic center. Subjects and Methods: Inclusion criteria were patients with glottic gap due to previous endoscopic phonosurgery, VF scars, vocal cord atrophy, and sulcus vocalis. Forty patients who underwent endoscopic injection of hyaluronic acid under general anesthesia were enrolled. Two different injections sites were used: the thyroarytenoid muscle in cases of glottic gap for augmentative purposes, and the lamina propria for treatment of scars and sulcus vocalis. A voice-evaluation protocol was performed before surgery, at the first follow-up visit (3 mo), and at the final follow-up (12 mo). Results: Follow-up data at three months were available for 38 patients, while data at 12 months follow-up were available for 27 patients. No side effects, hematoma, or infection and allergic reactions were reported in either the perioperative or postoperative period. Patients had statistically significant improvement in voice parameters compared with the baseline data at the first follow-up visit and at the 12-month follow-up. Conclusion: ACP-based gel seems to be a new tool in the challenging treatment of VF scarring, functioning as both an anti-adhesive product and an augmentation agent. Improvements in all glottal parameters and in both objective and subjective evaluation of voice performance were observed. © 2010 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

Objective: To document the efficacy of polydimethylsiloxane (PDMS) injections in patients with swallowing disorders after partial supracricoid laryngectomy; to assess the importance of quality-of-life (QOL) outcome in oncologic patients. Subjects and Methods: The study included 11 patients with swallowing disorders after partial laryngectomy and appropriate rehabilitation. They were treated with endoscopic injection of PDMS; QOL was investigated with four questionnaires (M.D. Anderson Dysphagia Inventory, Performance Status Scale for Head and Neck Cancer, Performance Karnofsky Scale, and Voice Handicap Index-10) before and after surgical treatment and further rehabilitation. Results: A significant improvement in QOL of all 11 patients was seen after endoscopic injection. The impact of this treatment on the social life of patients was considerable. Conclusion: Swallowing disorders and speech problems are quite common complications of partial laryngectomy. QOL in oncologic patients is a mandatory outcome measure. PDMS injection showed an improvement in the everyday life of selected patients. © 2009 American Academy of Otolaryngology-Head and Neck Surgery Foundation.

Obesity is recognized as playing an important role in causing snoring and in turning simple snoring into obstructive sleep apnea syndrome (OSAS). From our series of patients with sleep disturbances, we studied a group of 43 normal-weight snorers in whom we detected a significant number of OSAS episodes. An articulated diagnostic protocol was adopted, and Müller's maneuver was extensively applied. The resulting data were compared to data from a group of 43 obese patients from the same series. The major risk factor for developing OSAS in normal-weight snorers appears to be anatomic abnormalities, in particular, septal deviation and base of tongue hypertrophy. Soft palate hypertrophy alone is not enough, although in obese snorers it can produce a sleep disorder. The normal-weight snorer needs to be thoroughly investigated because of the significant risk of developing OSAS and for the detection of multiple concomitant sites of obstruction.

First branchial cleft cysts develop as a result of incomplete fusion of the cleft between the first and second branchial arches. In 1972, Work introduced a modified classification of these anomalies that recognized the existence of two types. Type I lesions, which are extremely rare, present as a cystic mass posterior to the pinna and concha. Type II lesions represent a duplication of both the membranous and cartilaginous portions of the external ear canal. They are associated with fistulas in the concha or in the external ear canal. Clinical and surgical management is often difficult because these anomalies have a variable relationship to the facial nerves. We describe a rare localization of a type I first branchial cleft cyst in a child and the clinical management with successive surgical treatment.

ObjectivesWe describe the experience of our otolaryngology department in the treatment of Forestier disease, particularly regarding the diagnostic process, surgical treatment, and postoperative outcomes.MethodsThe charts of 12 patients who underwent surgical treatment of Forestier disease between January 1, 2003, and January 1, 2009, were analyzed. All patients were subjected to clinical, radiologic, and endoscopic evaluation that confirmed the presence of cervical osteophytes. All patients were treated by a right-sided prevascular transcervical approach to remove cervical osteophytes. A literature review on Forestier disease was also carried out.ResultsOne case of immediate postoperative hemorrhage was reported. During the postoperative follow-up, ranging from 1 to 5 years, all patients underwent cervical radiography and fiberoptic laryngoscopy that confirmed no evidence of recurrence, and all patients remained asymptomatic.ConclusionsA prevascular transcervical right-sided approach seems to be an effective treatment for surgical removal of hyperostosis in Forestier disease, with an acceptable rate of complications and recurrence.
