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.

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.

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.

Treatment of Recurrent Tracheocutaneous Fistulas in the Irradiated Neck with a Two Layers-Two Flaps Combined Technique.

The development of a tracheocutaneous fistula (TCF) is a well-documented complication after tracheostomy, especially in chronic morbid patients, in whom tubes or cannulas are left in place over time, or in irradiated patients. Surgical treatments are therefore needed which range from simple curettage and dressings to local skin flaps, muscle flaps and, in the more complex cases, microsurgical free tissue transfers. We present a novel combined technique used to successfully treat recurrent TCFs in irradiated patients, involving a superiorly based turnover fistula flap and a sternocleidomastoid transposition flap.

Oncological outcomes of parotid gland malignancies: a retrospective analysis of 74 patients.

INTRODUCTION: Salivary gland malignancies are rare neoplasms whose management has been evolving over the last two decades. Nevertheless, patient outcomes have not improved accordingly. OBJECTIVE: In the present paper, factors and variables that could influence Overall, Disease-Specific and Disease-Free Survival, and Loco-Regional Control were analyzed. METHODS: Chart data from 74 patients who underwent parotid gland surgery were retrospectively analyzed and stratified for tumor histology, grading, size, pT stage, pN stage, extracapsular spread, involved salivary gland lobe, and age at diagnosis. Major outcomes were estimated at 5 years by Kaplan-Meier curves. RESULTS: Advanced stage, high grade, and lymph nodes involvement greatly impaired patient outcomes. Furthermore, in our cohort, the age at diagnosis ≥ 55 was a cause of poorer disease survival likely due to a different distribution in tumor histotypes between older and younger patients. Despite the two groups were homogeneous for the numerosity of squamous cell carcinomas, older patients were more rarely affected by mucoepidermoid and acinic cell carcinomas, which have generally better prognosis. Finally, patients aged ≥ 55 had a more frequent pathological involvement of the deep lobe of the parotid gland if compared to the younger counterpart. CONCLUSION: The rarity of some salivary gland tumor histotypes requires further high-number series to fully understand the prognostic factors for both patient survival and recurrence development. In our cohort, the age at diagnosis ≥ 55 raises concerns that play crucial roles in disease survival shortening.

Microvascular reconstruction two years after subtotal glossectomy: Is it worth it?

We ought to report an unusual case of a 49-year-old patient who underwent delayed reconstruction of the oral cavity defect, with an anterolateral thigh flap, two years after surgical demolition and adjuvant chemo-radiotherapy. At the end of oncologic treatment, he could not eat through oral route and presented evident speech articulation difficulties. After surgical reconstruction, swallowing assessment showed an improvement of swallowing with no gross signs of airways inhalation. His understandability of speech improved as well. Delayed reconstruction by a microvascular free flap with exclusive functional rehabilitation intent is feasible and may have satisfactory functional outcomes.

Acquisition of surgical skills for endoscopic ear and lateral skull base surgery: a staged training programme.

SUMMARY: Endoscopic ear surgery is radically changing the treatment of several middle and inner ear pathology, but its learning presents well-known manual and technical difficulties. The aim of this paper is be to present a training programme based on a modular model of increased difficulties. The experience from 2007 to 2016 at the University Hospital of Modena and University Hospital of Verona was reviewed and analysed for further considerations and to establish stages of training. The increasing experience of expert surgeons who deal with this kind of surgery represented the main guide to establish the steps and progression of training. In addition, the potential risk of damage of vascular structures or nerves represents fundamental criteria for progression toward higher levels. Some not-mandatory skills were also suggested for stage of difficulty. Five stages of training were deemed appropriate for progressive learning of endoscopic ear and lateral skull base surgery, ranging from simple middle and external ear procedures to surgery of inner ear and internal auditory canal. Mastering of each level is suggested before attempting procedures at a higher level, in particular for procedures involving lateral skull base. Standardisation and adoption of modular incremental training are expected to facilitate improvement of otolaryngologists and neurosurgeons starting with endoscopic middle ear and lateral skull base surgery. Adherence to such a programme during the growth phase may potentially decrease the rate of complications, making the training programme safer.

Unravelling the risk factors that underlie oral and oropharyngeal surgery in elderly.

Oral squamous cell carcinoma (OSCC) diagnoses in elderly patients are expected to double in the next 20 years. Current guidelines suggest surgery as a preferred approach, but elderly patients are hardly considered suitable to challenging surgical treatments. Using a multi-centric retrospective analysis, we evaluated the outcomes of 99 patients affected by OSCC and aged at least 70, who underwent to either transoral procedures (TP), open neck resection without (OR) or with reconstruction (ORR). In our cohort, overall survival was significantly hampered by concomitant diseases and postsurgical complications, whose development is driven by the former. Thus, our findings support the growing acceptance that chronological age alone should not be a sufficient contraindication for aggressive surgery in the treatment of OSCC. However, elderly patients affected by OSCC are undoubtedly delicate surgical candidates and accurate selection prior to surgery with curative intent is mandatory.

A mild phenotype of sensorineural hearing loss and palmoplantar keratoderma caused by a novel GJB2 dominant mutation.

Dominant GJB2 mutations are known to cause a syndromic form of sensorineural hearing loss associated with palmo-plantar skin manifestations. We present the genotype/phenotype correlations of a new GJB2 mutation identified in three generations of an Italian family (proband, mother and grandfather) whose members are affected by sensorineural hearing impairment associated with adult-onset palmoplantar keratoderma. In all affected members we identified a new heterozygous GJB2 mutation (c.66G > T, p.Lys22Asn) whose segregation, population frequency and in silico prediction analysis have suggested a pathogenic role. The p.Lys22Asn GJB2 mutation causes a dominant form of hearing loss associated with variable expression of palmoplantar keratoderma, representing a model of full penetrance, with an age-dependent effect on the phenotype.

Expanded transcanal transpromontorial approach to the internal auditory canal and cerebellopontine angle: a cadaveric study.

The aim of this paper is to describe and evaluate the feasibility of an expanded endoscopic transcanal transpromotorial approach (ExpTTA) to the internal auditory canal and the cerebellopontine angle. To this end, we performed a cadaveric dissection study in September 2015. In total, 2 heads (4 sides) were dissected focusing on anatomical landmarks and surgical feasibility. Data from dissections were reviewed and analysed for further consideration. In all 4 sides of the cadavers the procedure was feasible. In all cadavers, it was necessary to extensively drill the temporo-mandibular joint and to calibrate the external ear canal to allow adequate room to manoeuver the instruments and optics and to comfortably access the cerebellopontine angle. In addition, thorough skeletonisation of the carotid artery and the jugular bulb were necessary for the same purpose. In conclusion, ExpTTA appeared to be successful to access the internal auditory canal and cerebellopontine angle region. Potential extensive and routine application of this type of approach in lateral skull base surgery will depend on the development of technology and surgical refinements and on the diffusion of skull base endoscopic skills among otolaryngologists and neurosurgical community.

Unravelling the risk factors that underlie laryngeal surgery in elderly.

Older patients are not considered good candidates to undergo more challenging therapeutic treatments, e.g. highly invasive surgery and complex chemotherapy. However, their exclusion from standard therapeutic options is not justifiable. Herein, we reviewed 212 patients aged ≥ 70, affected with laryngeal squamous cell carcinoma, and treated with transoral laser microsurgery or open neck (partial / total) laryngectomy with radical intent. The main aim was to compare patient outcomes to identify predictive factors that can be used by surgeons to choose the most appropriate treatment option. In our cohort, patients affected with more advanced tumour and hence treated by invasive open neck surgeries (above all TL) are more prone to develop complications and undergo fatal outcome than those with early disease treated by laser microsurgery, independently of age at surgery. In conclusion, elderly patients affected by laryngeal cancer can be treated similarly to younger patients, keeping in mind that more invasive surgeries are associated with a higher risk of developing complications. The advantages of mini-invasive surgery make it a possible first choice treatment in very old and frail patients suffering from laryngeal cancer, especially considering the recent success in treatment of some advanced stage tumours. Furthermore, comorbidities, by themselves, should not be used as exclusion criteria for subjecting an elderly patient to a different treatment that is from standard therapy.

Supratracheal laryngectomy: current indications and contraindications.

Cancer of the larynx in the intermediate/advanced stage still presents a major challenge in terms of controlling the disease and preserving the organ. Supratracheal partial laryngectomy (STPL) has been described as a function-sparing surgical procedure for laryngeal cancer with sub-glottic extension. The aim of the present multi-institutional study was to focus on the indications and contraindications, both local and general, for this type of surgery based on the long-term oncological and functional results. We analysed the clinical outcomes of 142 patients with laryngeal cancer staged pT2-pT4a who underwent STPL. Five-year overall survival (OS), disease-specific survival (DSS), disease-free survival (DFS) and loco-regional control (LRC) rates were: glottic pT2 [71.4%, 95.2%, 76.0%, 76.0%], glottic-transglottic pT3 [85.3%, 91.1%, 86.4%, 88.7%], and pT4a [73.2%, 88.1%, 52.7%, 60.7%], respectively. DFS and LRC prevalences at 5 years were greatly affected by pT4a staging. Five-year laryngeal function preservation (LFP) and laryngectomy free survival (LFS) were: glottic pT2 [90.9%, 95.2%], glottic-transglottic pT3 [84.4%, 93.1%], and pT4a [63.7%, 75.5%], respectively, being affected by pT staging and age 65 ≥ years (LFP 54.1%). As a result of Type III open horizontal partial laryngectomies (OPHLs) (supratracheal laryngectomies), the typical subsites of local failure inside the larynx were the mucosa at the passage between the remnant larynx and trachea, the mucosa at the level of the posterior commissure and the contralateral cricoarytenoid unit as well as outside the larynx at the level of the outer surface of the remnant larynx. For patients with glottic or transglottic tumours and with sub-glottic extension, the choice of STPL can be considered to be effective, not only in prognostic terms, but also in terms of functional results.

Nimodipine in otolaryngology: from past evidence to clinical perspectives.

As L-type voltage-gated calcium channels (VGCCs) control Ca(2+) influx and depolarisation of cardiac and vascular smooth muscle, they represent a specific therapeutic target for calcium channel blockers (CCBs), which are approved and widely used to treat hypertension, myocardial ischaemia and arrhythmias. L-type currents also play a role in calcium entry in the sensory cells of the inner ear. In hair cells of both cochlea and labyrinth, calcium cytoplasmic influx is the first physiological process that activates complex intracellular enzymatic reactions resulting in neurotransmitter release. Excessive calcium ion entry into sensory cells, as a consequence of L-VGCCs malfunction is responsible for over-activation of phospholipase A2 and C, protein kinase II and C, nitric oxide synthase and both endonucleases and depolymerases, which can cause membrane damage and cellular death if the cytoplasmic buffering capacity is overcome. Nimodipine, a highly lipophilic 1-4 dihydropyridine that easily crosses the brain-blood barrier, is generally used to reduce the severity of neurological deficits resulting from vasospasm in patients with subarachnoid haemorrhage. Moreover, due to its selective blocking activity on L-channel calcium currents, nimodipine is also suggested to be an effective countermeasure for cochlear and vestibular dysfunctions known as channelopathies. Indeed, experimental data in amphibians and mammalians indicate that nimodipine has a stronger efficacy than other CCBs (aminopyridine, nifedipine) on voltage-dependent whole-cell currents within hair cells at rest and it is the only agent that is also effective during their mechanically induced depolarisation. In humans, the efficacy of nimodipine is documented in the medical management of peripheral vestibular vertigo, sensorineural hearing loss and tinnitus, even in a pathology as complex as Ménière's disease. Nimodipine is also considered useful in the prophylaxis of damage to the facial and cochlear nerves caused by ablative surgery of cerebellopontine tumours; it has been recently hypothesised to accelerate functional recovery of recurrent nerve lesions during thyroid cancer surgery. Further trials with adequate study design are needed to test the efficacy of nimodipine in the treatment of vertigo due to cerebrovascular disease and vestibular migraine.

Analysis of risk factors for pharyngocutaneous fistula after total laryngectomy with particular focus on nutritional status.

Pharyngocutaneous fistula (PCF) is the most common complication following total laryngectomy and the most difficult to manage. It often causes increased morbidity, delays starting adjuvant therapy, prolongs hospitalisation, increases treatment costs and reduces the quality of life (QoL). The objective of this study is to analyse the predisposing factors and the most important nutritional parameters related to the development of PCF in patients undergoing total laryngectomy and to suggest medical alternatives that might improve results. We performed a retrospective study of 69 patients who underwent either primary or salvage total laryngectomy in our department between January 2008 and January 2012. Risk factors for fistula formation were analysed including tumour characteristics (histology, grading, AJCC stage), treatment (primary or salvage surgery, extent of resection, flap reconstruction, preoperative radiotherapy), comorbidity and nutritional status (preoperative haemoglobin, albumin and prealbumin levels and their changes during hospitalisation). Twenty-four patients developed a PCF (overall incidence 34.8%). Fistula formation was significantly higher in patients with diabetes, preoperative malnutrition (identified from low preoperative albumin and prealbumin levels). After specific nutritional evaluation and support, no patient developed a PCF. Risk factors for PCF formation are extensively treated in the literature but identification of high-risk patients is still controversial. Our study demonstrates that nutritional status of the patient, assessed by preoperative albumin, is also an important risk factor for PCF formation in addition to classical factors. Maintenance of a normal perioperative nutritional status can be helpful to avoid this complication.

Clinical presentation and treatment outcomes of thyroglossal duct cysts: a systematic review.

The aim of the present review was to analyze the main clinical signs and symptoms observed in patients with thyroglossal duct cysts (TGDCs). Secondarily we investigated the outcomes following the different types of treatment of TGDCs in children and adults. Three selected strings were run on the PubMed database to retrieve articles on these topics. A double cross-check was performed on citations and full-text articles were identified using the study inclusion and exclusion criteria. A meta-analysis was performed of the data obtained. Overall, 356 articles were identified; 24 (comprising a total of 1371 subjects) satisfied the inclusion and exclusion criteria. On the basis of the meta-analysis, the presence of a neck cystic mass was the main clinical presentation of TGDCs, with a mean rate of 75% (95% confidence interval 72-79%). The mean local wound infection rate was 4% (95% confidence interval 3-6%), this being the most frequent complication following treatment. The mean rate of overall recurrence was 11% (95% confidence interval 9-14%). The Sistrunk procedure appears to be the better choice for the therapy of TGDCs to avoid recurrences. Further studies on larger cohorts of patients regarding the minimally invasive treatment options would be helpful to elucidate and endorse their utilization in selected cases.

Results of Early Versus Intermediate or Delayed Voice Therapy in Patients With Unilateral Vocal Fold Paralysis: Our Experience in 171 Patients.

OBJECTIVES: Vocal fold paralysis can have an important impact on a patient's quality of life. The goal of this study was to compare, in terms of vocal improvement and motility recovery, the post-vocal treatment results of our patients with unilateral vocal fold paralysis (UVFP) when treatment was started early (within 4 weeks from injury) versus intermediate (from 4 to 8 weeks) or delayed (at least 8 weeks after injury) treatment. STUDY DESIGN: An 11-year retrospective study of patients with UVFP who underwent multidimensional diagnostic-therapeutic assessment. METHODS: In total, 171 patients with UVFP were included in our study, divided into three groups who underwent early (first group), intermediate (second group), or delayed (third group) voice treatment. All patients underwent voice therapy based on forcible exercises supplemented by manipulations and maneuvers. RESULTS: Of the 171 patients with UVFP, 106 (62%) recovered vocal fold motility. Of these 106 patients, 51/78 (65%) were in the first group, 30/49 (61%) in the second group, and 25/44 (56%) in the third group. A significant (P < 0.0001) reduction in fundamental frequency (Fo) was present in the first group with a manifest improvement in the mean values of Jitter (Jitt%; P = 0.001), Shimmer (Shim%; P < 0.0001), and noise-to-harmonic ratio (NHR; P < 0.0001). A significant (P < 0.0001) reduction in Fo was found in the second group with a manifest improvement in Jitt% (P < 0.001), Shim% (P < 0.0001), and NHR (P < 0.0001). For the third group, no values were statistically significant apart from the improvement in NHR (P < 0.001). CONCLUSIONS: This study confirms the importance of early rehabilitation underlining the non-functional vocal recovery in patients who started treatment later than 8 weeks after injury.

Partial laryngectomies: when the problem is the pexy.

To analyse the complications related to pexy, the main clinical manifestations that may raise suspicions of a pexy line rupture/detachment, the most suitable diagnostic technique and the optimum treatment to resolve this complication. This is a retrospective chart review in tertiary university referral centre. Medical charts of patients with oncological laryngeal pathologies admitted to the Otolaryngology Department of the University Hospital of Modena between May 2003 and March 2012 were analysed. Ten patients with rupture of the pexy were identified and included in the present study. The clinical manifestations were dysphagia, alteration of sensitivity of hypopharyngeallaryngeal structures, fever, infection and diastasis of surgical wounds, bleeding, dysphonia and aspiration pneumonia. Rupture of the pexy was diagnosed through endoscopic evaluations, radiological techniques or directly in the operating room during revision surgery of the earlier operation. Surgical treatments, coupled with effective swallowing rehabilitation, allowed progressive functional recovery. Patients were hospitalised until recovery of laryngeal functions was complete. In conclusion, pexy line rupture is one of the complications in the post-operative period of partial laryngectomies. Certain clinical manifestations may indicate this complication, helping the surgeon to establish an early diagnosis and administer prompt treatment.

Results of endoscopic middle ear surgery for cholesteatoma treatment: a systematic review.

Traditional surgery for cholesteatoma of the middle ear is performed by microscopic approaches. However, in recent years endoscopic instrumentation, techniques and knowledge have greatly improved, and in our opinion endoscopic surgical techniques will gain increasing importance in otologic surgery in the future. The aim of this study was to focus on outcomes obtained using endoscopic surgery for the treatment of middle ear cholesteatoma. A systematic review of the literature was performed. A total of 7 articles comprising 515 patients treated exclusively with endoscope or with a combined technique were found. During post-surgical follow-up, 48 (9.3%) patients showed a residual or recurrent pathology. Despite the small number of patients analyzed in our review, the outcomes of this technique appear to be promising. In particular, concerning the rates of recurrences and residual disease, endoscopic middle ear surgery appears to guarantee similar results in comparison to classic microscopic approaches with the advantage of performing minimally invasive surgery.
