Endoscopic push through tragal cartilage tympanoplasty: A 10-year retrospective review of our technique and outcomes

BACKGROUND

Endoscopic ear surgery (EES) provides a magnified, high-definition view of the otological surgical field. EES allows otologists to avoid surgical incisions and associated postoperative complications. It is an ideal technique for the performance and teaching of tympanoplasty.

AIM

To examine the efficacy of total Endoscopic Push Through Tragal Cartilage Tympanoplasty (EPTTCT), at our institution over a 10-year period.

METHODS

A retrospective analysis of 168 cases of EPTTCT for closure of small to medium tympanic membrane perforations from 2013-2023 was conducted. Patient sex, age range (pediatric vs adult), etiology of injury, success rate, complications, and postoperative hearing status were collected.

RESULTS

Graft uptake results indicated success in 94% of patients, with less than a 2% complication rate. Postoperative pure tone audiometry demonstrated hearing status improvement in 69% of patients.

CONCLUSION

EPTTCT has been shown to be effective in tympanic membrane perforation closures with minimal complications. This study further demonstrates the efficacy and safety of these procedures in a single-center review.

Usher syndrome: Genetic diagnosis and current therapeutic approaches

Usher Syndrome (USH) is the most common deaf-blind syndrome, affecting approximately 1 in 6000 people in the deaf population. This genetic condition is characterized by a combination of hearing loss (HL), retinitis pigmentosa, and, in some cases, vestibular areflexia. Among the subtypes of USH, USH type 1 is considered the most severe form, presenting profound bilateral congenital deafness, vestibular areflexia, and early onset RP. USH type 2 is the most common form, exhibiting congenital moderate to severe HL for low frequencies and severe to profound HL for high frequencies. Conversely, type 3 is the rarest, initially manifesting mild symptoms during childhood that become more prominent in the first decades of life. The dual impact of USH on both visual and auditory senses significantly impairs patients’ quality of life, restricting their daily activities and interactions with society. To date, 9 genes have been confirmed so far for USH: MYO7A, USH1C, CDH23, PCDH15, USH1G, USH2A, ADGRV1, WHRN and CLRN1. These genes are inherited in an autosomal recessive manner and encode proteins expressed in the inner ear and retina, leading to functional loss. Although non-genetic methods can assist in patient triage and disease extension evaluation, genetic and molecular tests play a pivotal role in providing genetic counseling, enabling appropriate gene therapy, and facilitating timely cochlear implantation (CI). The CRISPR/Cas9 system and viral-based gene replacement therapy have recently emerged as highly promising techniques for treating USH. Regarding drug therapy, PTC-124 and Nb54 have been identified as promising drug interventions for genetic HL in USH. Simultaneously, CI has proven to be critical in the restoration of hearing. This review aims to summarize the genetic and molecular diagnosis of USH and highlight the importance of early diagnosis in guiding appropriate treatment strategies and improving patient prognosis.

Post-COVID-19 persistent olfactory, gustatory, and trigeminal chemosensory disorders: Definitions, mechanisms, and potential treatments

The nose and the oral cavities are the main sites for severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) entry into the body. Smell and taste deficits are the most common acute viral manifestations. Persistent smell disorders are the most common and bothersome complications after SARS-CoV-2 infection, lasting for months to years. The mechanisms and treatment of persistent post-coronavirus disease 2019 (COVID-19) smell and taste disorders are still challenges. Information sources for the review are PubMed, Centers for Disease Control and Prevention, Ovid Medline, Embase, Scopus, Web of Science, International Prospective Register of Systematic Reviews, Cumulative Index to Nursing and Allied Health Literature, Elton Bryson Stephens Company, Cochrane Effective Practice and Organization of Care, Cooperation in Science and Technology, International Clinical Trials Registry Platform, World Health Organization, Randomized Controlled Trial Number Registry, and MediFind. This review summarizes the up-to-date information about the prevalence, patterns at onset, and prognoses of post-COVID-19 smell and taste disorders, evidence for the neurotropism of SARS-CoV-2 and the overlap between SARS-CoV-1, Middle East respiratory syndrome coronavirus, and SARS-CoV-2 in structure, molecular biology, mode of replication, and host pathogenicity, the suggested cellular and molecular mechanisms for these post-COVID19 chemosensory disorders, and the applied pharmacotherapies and interventions as trials to treat these disorders, and the recommendations for future research to improve understanding of predictors and mechanisms of these disorders. These are crucial for hopeful proper treatment strategies.

Wet cupping (Al-hijamah) as a strange cause of ear trauma: A case report

BACKGROUND

Cupping therapy is used across the globe since ancient Egypt. It is used as a complementary or alternative to daily clinical practice. Cupping therapy could be dry or wet (Al-hijamah) type. It is considered a relatively safe procedure for a variety of clinical problems like lower backache, shoulder pain, neck pain, headache, and migraine. Application of cupping therapy over body orifices is contraindicated.

CASE SUMMARY

A 27-year-old gentleman presented with sudden left-sided hearing loss and tinnitus for 7 d. He gave a history of upper respiratory tract infection 14 d before his complaints. He received Al-hijamah over his left ear 3 d before seeking advice from the Otolaryngology clinic, but without benefit. Physical examination showed a dull-looking left ear drum, hemotympanum in the posterior part of the tympanic cavity, two blood clots over the eardrum, and multiple bleeding points over the external ear canal and tympanic membrane. A pure tone audiogram and tympanogram confirmed the diagnosis of middle ear effusion. Conservative treatment (avoidance of water entry, antibiotics, and local and systemic decongestants) was given for 5 d. The presenting symptoms as well as ear injuries resolved completely two weeks after the follow-up.

CONCLUSION

We do not recommend using Al-hijamah directly over the ear as a treatment option for hearing loss to avoid unwanted ear trauma as well as there is no benefit from this kind of treatment.

Transoral robotic surgery for adult parapharyngeal lymphangioma: A case report

BACKGROUND

Lymphangiomas are a group of benign swellings which are commonly seen in children. The most common sites of presentation is the head and neck region, less commonly seen in axilla, chest, liver, spleen, etc. The ideal modality of treatment has always been surgical excision irrespective of the site and age group. But with the advent of minimally invasive surgical techniques, it is now possible to perform excision of parapharyngeal space lesions with minimal morbidity and good clearance.

CASE SUMMARY

A 42-year-old male patient who presented with difficulty in swallowing and had undergone surgery twice outside, where Transcervical approach was attempted to remove the parapharyngeal mass, but failed. Magnetic resonance imaging scan demonstrated a 6 cm x 5 cm x 4 cm left parapharyngeal mass. He underwent transoral robotic surgery for the excision of the parapharyngeal lesion and had an uneventful post-operative recovery.

CONCLUSION

Lymphangiomas are hamartomatous swellings which are benign in nature. The symptoms of the patient with large parapharyngeal mass include dysphagia, dyspnoea and neck swelling. Clinicoradiological evaluation is of utmost importance to determine the adjacent vital structures and the approach to the tumor. With the advent of robotics in oncology, transoral robotic excision is one of the best approaches to perform such a surgery.

Examining the life-cycle of the Coblator II device: Increases in paediatric post-tonsillectomy haemorrhage after six years of use

All paediatric tonsillectomies were examined from 2012 – 2019 at a single tertiary-referral institution, and all were performed by one of two paediatric otolaryngologists. One exclusively used the diathermy, the other exclusively used the Coblator II. Two Coblator units were purchased simultaneously in 2012 and not replaced. There was no significant difference in number of tonsillectomies performed (1298 via diathermy, 1221 via Coblator), nor in postoperative day of bleed, patient age, indication for procedure, and no patient had an underlying coagulopathy. The most common indication for tonsillectomy in both groups was sleep-disordered breathing. There was no significant difference in postoperative haemorrhage rates between groups for the first six years of the study (0%-1.4%/year). Years 7 and 8 saw the Coblator group haemorrhage rate significantly increase (0%-0.6% diathermy group vs 2%-3% Coblator group), though still fell within accepted rate of postoperative haemorrhage. The devices were then replaced, and the differences in haemorrhage disappeared. There appears to be a significant increase in paediatric post-tonsillectomy haemorrhage when using a Coblator device greater than six years old. This may suggest a useful lifespan for the Coblator II device.

Medical malpractice litigation involving otolaryngology residents and fellows: A case-based 30-year review

BACKGROUND

Errors, misdiagnoses, and complications can occur while trainees are involved in patient care. Analysis of such events could reveal areas for improvement by residency and fellowship programs.

AIM

To examine lawsuits tried at the state and federal level involving otolaryngology trainees.

METHODS

The LexisNexis database, an online legal research database containing state and federal case records from across the United States, was retrospectively reviewed for malpractice cases involving otolaryngology residents or fellows from January 1, 1990 to December 31, 2020. Case data collected: Plaintiff/trainee/defendant characteristics, allegations, medical outcomes, and legal outcomes.

RESULTS

Over the study period, 20 malpractice lawsuits involving otolaryngology trainees were identified. Plaintiffs raised numerous allegations including procedural error (n = 12, 25.5%), incorrect diagnosis and/or treatment (n = 8, 17.0%), and lack of knowledge of trainee involvement (n = 6, 12.8%). Nine cases (45%) had verdicts in favor of the plaintiff, whereas 5 cases (25%) had verdicts in favor of the defense. Six cases (30%) ended in a settlement. Awards to plaintiffs were heterogenous, with a median of $617,500 (range $32K-17M) for settled cases and verdicts favoring plaintiffs.

CONCLUSION

The findings enclosed herein represent the first published analysis of trainee involvement in otolaryngology malpractice cases held at the state/federal level. Otolaryngology trainees can be involved in lawsuits for both procedural and nonprocedural events. This study highlights the importance of education specifically in the domains of procedural errors, informed consent, proper diagnosis/management, and clear communication within patient care teams. Training programs should incorporate these study findings into effective simulation courses and didactic sessions. Educating trainees about common pitfalls holds the promise of decreasing healthcare systems costs, reducing trainee burnout, and, most importantly, benefiting patients.

Synovial osteochondromatosis of the temporomandibular joint: A case report

BACKGROUND

Synovial osteochondromatosis is a rare but benign condition that can result in significant impairment of joint functionality. This case report documents an uncommon presentation of this disorder occurring within the temporomandibular joint, causing the patient significant pain, trismus, and difficulty with daily activities such as eating and speaking. A review of the literature including disease mechanisms and previously documented cases is included to provide comprehensive background for clinical decision-making.

CASE SUMMARY

A 48-year-old male patient presented with a 3-mo history of trismus, crepitus with jaw movement and significant pain while chewing. Physical examination revealed a firm mass and tenderness to palpation at the right temporomandibular joint. Further workup revealed a bilobed mass extending into the joint space as well as significant bony erosion of the glenoid fossa. The patient underwent mass excision with joint reconstruction and pathology revealed synovial osteochondromatosis. The patient reported significant improvement in his symptoms postoperatively.

CONCLUSION

This report outlines the investigative approach and treatment course of synovial osteochondromatosis. The positive outcome following surgical intervention in this case emphasizes the importance of interdisciplinary collaboration and the potential for improvement in quality of life of this patient population.

CX3CR1 receptor as a potential therapeutic target in chronic rhinosinusitis and allergic rhinitis

Chronic rhinosinusitis and allergic rhinitis are chronic inflammatory diseases that affect the mucous membrane of the nose and paranasal sinuses. These diseases are characterized by recruitment of inflammatory cells to the upper airway. For this to take place a complex interaction between inflammatory cells and the cytokines/chemokines (ligand) liberated at the site of inflammation is involved in a process termed chemotaxis or directed cell migration against concentration gradient of the ligand. This entails signal transduction through the cell surface receptor resulting in cellular functional response and directed migration. In this editorial the novel role of CX3CR1 receptor in the immunopathology of chronic inflammation of the nose and paranasal sinuses will be explored with its potential role as therapeutic target in chronic nasal inflammation.

Effect of intranasal stents (AlaxoLito, AlaxoLito Plus and AlaxoLito Xtreme) on the nasal airway: A case report

BACKGROUND

The study of intranasal stents on the nasal airway is limited in the medical literature. The authors aim to provide objective measurements on their effects on the nasal airway. The aim is to study the feasibility of three novel intranasal stenting devices, AlaxoLito, AlaxoLito Plus, and AlaxoLito Xtreme, as treatment for nasal obstruction.

CASE SUMMARY

A 58- year-old man, who had right sided nasal obstruction, used stents during sporting activities intermittently for four years and subsequently in addition to intermittent sports use regularly for sleep for another two years. Magnetic resonance imaging (MRI) of the nasal passages and rhinomanometric measurements were taken with and without stents in situ. The stents tested are all braided from thin nitinol wires. The AlaxoLito Nasal Stent has a length of 35 mm. The AlaxoLito Plus and AlaxoLito Xtreme Nasal Stents have a length of 60 mm. Both have a diameter of about 10 mm in unloaded state and comprise a widened, ball-shaped section (which is positioned at the nasal alar) of about 11 and 14 mm, respectively. Rhinomanometric nasal airflow after application of the stents improved 1.11, 1.23, and 1.38 fold, respectively, with application of the AlaxoLito, AlaxoLito Plus and AlaxoLito Xtreme stents. MRI showed that after application of the stents, the nasal passage increased in diameter.

CONCLUSION

Intranasal stenting shows improvement in nasal airflow. Intermittent and regular longterm use had been shown to be safe, with no discomfort and no side effects.

Day case paediatric microlaryngobronchosocopy: A prospective study

AIM

To assess the feasibility and parental acceptance of diagnostic microlaryngobronchoscopy (MLB) as day case surgery.

METHODS

A prospective study was performed over a 26 mo period at a tertiary paediatric ENT centre. Patients were selected in clinic using set criteria. All MLBs were performed using a standardised anaesthetic protocol and patients monitored post-operatively. Six weeks following surgery, parents underwent questionnaire surveys.

RESULTS

Ninety-four out of 101 MLBs was successfully performed as day case surgery over the set period. Seven patients required an overnight stay for further observation. Fifty-seven parents took part in the questionnaire of which 68.4% were highly satisfied with same day discharge.

CONCLUSION

MLB is feasible, safe and acceptable as day case surgery in carefully selected patients.

Meatoplasty: A novel technique and minireview

We describe a modified aural meatoplasty technique. The technique has been mainly used for mastoid surgery but it may also be used to address other causes of meatal stenosis. It involves removing most of the cartilage in the conchal bowl and soft tissue in the external auditory meatus. Cartilage from the helical root may also be sacrificed as part of this procedure. Our technique produces an excellent cosmetic result and an adequate meatoplasty which is easy to monitor in the outpatient setting.

Embryology of the nose: The evo-devo concept

Aim was to gather relevant knowledge in evolution and development to find a rational explanation for the intricate and elaborate anatomy of the nose. According to classic embryology, the philtrum of the upper lip, nasal dorsum, septum and primary palate develop from the intermaxillary process, and the lateral walls of the nasal pyramid from the lateral nasal processes. The palatal shelves, which are outgrowths of the maxillary processes, form the secondary palate. The median nasal septum develops inferiorly from the roof of the nasal cavity. These valuable embryologic data do not explain the complex intricacy of the many anatomical structures comprising the nose. The evo-devo theory offers a rational explanation to this complex anatomy. Phylogenically, the nose develops as an olfactory organ in fish before becoming respiratory in tetrapods. During development, infolding of the olfactory placodes occurs, bringing the medial olfactory processes to form the septolateral cartilage while the lateral olfactory processes form the alar cartilages. The olfactory fascia units these cartilages to the olfactory mucosa, that stays separated from brain by the cartilaginous olfactory capsule (the ethmoid bone forerunner). Phylogenically, the respiratory nose develops between mouth and olfactory nose by rearrangement of the dermal bones of the secondary palate, which appears in early tetrapods. During development, the palatal shelves develop into the palatine processes of the maxillary bones, and with the vomer, palatine, pterygoid and inferior turbinate bones form the walls of the nasal cavity after regression of the transverse lamina. Applying the evolutionary developmental biology (evo-devo) discipline on our present knowledge of development, anatomy and physiology of the nose, significantly expands and places this knowledge in proper perspective. The clinicopathologies of nasal polyposis, for example, occurs specifically in the ethmoid labyrinth or, woodworker’s adenocarcinomas, occurring only in the olfactory cleft can now be explained by employing the evo-devo approach. A full understanding of the evo-devo discipline, as it pertains to head and neck anatomy, has profound implications to the otolaryngologist empowering his skills and abilities, and ultimately translating in improving surgical outcomes and maximizing patient care.

Use of Holmium:Yag laser in early stage oropharyngeal squamous cell cancer

AIM: To evaluate the efficacy of Holmium:Yag laser resection for oropharyngeal squamous cell cancer.

METHODS: A prospectively collected case series of all patients with oropharyngeal squamous cell carcinoma undergoing laser resection using the Holmium:Yag laser technique only over a 15 year period at a tertiary referral centre. All patients underwent long term follow up with regular clinical and radiological surveillance, when indicated. All patients were operated on under general anaesthetic with a laser-safe endotracheal tube. Typically laser resection was performed first using an operating microscope, followed by neck dissection. The tumour was held with a Luc’s forceps or Allis clamp. The Holmium:Yag laser was implemented via a fibre delivery system. The Holmium:Yag laser fibre, of 550 micron diameter, was inserted through a Zoellner sucker and attached via steri-strips to a second Zoellner suction to provide smoke evacuation. The settings were 1J/pulse, 15 Hz, 15 W in a continuous delivery modality via a foot pedal control. The procedure is simple, bloodless, effective and quick. All surgeries were performed as day cases.

RESULTS: Twenty-seven oropharyngeal squamous cell cancer patients were identified, at the following subsites: 23 lateral pharyngeal wall/tonsil, 2 anterior faucal and 2 tongue base. Of the 23 tonsil tumours, 19 required no further treatment (83% therefore had negative histopathological margins) and 4 required chemoradiotherapy (17% were incompletely excised or had aggressive histopathological features such as discohesive, perineural spread, vascular invasion). The 2 patients with anterior faucal pillar neoplasia needed no further treatment. Both tongue base cancer cases required further treatment in the form of chemoradiotherapy (due to positive histopathological margins). Postoperatively, patients complained of pain locally, which resolved with regular analgesia. There were no postoperative haemorrhages. Swallowing and speech were normal after healing (10-14 d). There was one case of fistula when neck dissection was carried out simultaneously; this resolved with conservative management. All patients were followed up with serial imaging and clinical examination for a minimum of five years. Median follow up was 84 mo.

CONCLUSION: Holmium:Yag lasers are a safe and effective treatment for Stage 1 and 2 squamous cell carcinoma of the oropharynx, excluding the tongue base.

Word perception in noise at different channels in simulated cochlear implant listeners

AIM: To find out effect of different signal-to-noise ratios (SNRs) on word perception at different number of channels.

METHODS: Thirty participants with normal hearing in the age range of 18-25 years (mean age 23.6 years) were involved in the study. For word perception test, there were 28 key-words embedded in sentences comprises of four lists processed for different channels (4, 8 and 32 channel) using AngelSim program at -5, 0 and +5 SNRs. The recorded stimuli were routed through audiometer connected with computer with CD player and presented in free field condition with speakers kept at 0° azimuth in a sound treated room.

RESULTS: Repeated measure ANOVA showed significant main effect across different SNRs at 4 channel, 8 channel and at 32 channel. Further, Bonferroni multiple pairwise comparisons shows significant differences between all the possible combinations (4, 8 and 32 channel) at +5 dB SNR, 0 dB SNR and -5 dB SNR.

CONCLUSION: Present study highlights the importance of more number of channels and higher signal to noise ratio for better perception of words in noise in simulated cochlear implantees.

Positron-emission tomography/computed tomography imaging in head and neck oncology: An update

Cancers of the head and neck account for more than half a million cases worldwide annually, with a significant majority diagnosed as squamous cell carcinoma (HNSCC). Imaging studies such as contrast-enhanced computed tomography (CT), magnetic resonance imaging (MRI) and ¹⁸F-2-fluoro-2-deoxy-D-glucose positron-emission tomography/computed tomography (¹⁸F-FDG PET/CT) are widely used to determine the presence and extent of tumors and metastatic disease, both before and after treatment. Advances in PET/CT imaging have allowed it to emerge as a superior imaging modality compared to both CT and MRI, especially in detection of carcinoma of unknown primary, cervical lymph node metastasis, distant metastasis, residual/recurrent cancer and second primary tumors, often leading to alteration in management. PET/CT biomarker may further provide an overall assessment of tumor aggressiveness with prognostic implications. As new developments emerged leading to better understanding and use of PET/CT in head and neck oncology, the aim of this article is to review the roles of PET/CT in both pre- and post-treatment management of HNSCC and PET-derived parameters as prognostic indicators.

X-linked deafness: A review of clinical and radiological findings and current management strategies

X-linked deafness is a rare genetic disorder causing a severe mixed hearing loss. This is due to an abnormal connection between the internal auditory meatus (IAM) and the basal turn of the cochlear leading to a “3^rd window effect” and cochlear conductive hearing loss. Patients are traditionally treated with conventional hearing aids however these are often unsatisfactory. Cochlear implantation is a high-risk procedure in such cases due to the risk of inadvertent electrode placement in the IAM. We present three paediatric cases where the hearing loss was managed with a combination of a bone anchored hearing aid in combination with a conventional behind the ear hearing aid. We also present a review of the current literature regarding the management of X-linked deafness.

Management of intratemporal facial nerve schwannomas: The evolution of treatment paradigms from 2000-2015

Intratemporal facial nerve schwannoma (FNS) are rare benign tumors of the skull base. Many of these tumors will be detected during evaluation for symptoms suggestive of vestibular schwannoma. However, there are several signs and symptoms which can suggest the facial nerve as the origin of the tumor. Intratemporal FNS can be multiple, like “beads on a string”, or solitary lesions of the internal auditory canal. This variable tumor morphology necessitates multiple treatment options to allow patients the best chance of preservation of facial nerve function. Historically FNS were managed with resection of the nerve with cable grafting. However this leaves the patient with permanent facial weakness and asymmetry. Currently most patients find this outcome unacceptable, especially when they present with good to normal facial nerve function. Facial paralysis has a significantly negative impact on quality life, so treatment regimens that spare facial nerve function have been used in patients who present with moderate to good facial nerve function. Nerve sparing options include tumor debulking, decompression of the bony facial canal, radiosurgery, and observation. The choice of management depends on the degree of facial nerve dysfunction at presentation, hearing status in the affected ear, medical comorbidities and patient preference. Each treatment option will be discussed in detail and suggestions for patient management will be presented.

It is 2015: What are the best diagnostic and treatment options for Ménière’s disease?

Ménière’s disease (MD) is a common cause of recurrent vertigo. Its pathophysiology is still unclear and controversial. The most common histological finding in postmortem temporal bone studies of patients is endolymphatic hydrops (EH). However, not all cases of hydrops are associated with MD and it may represent the end point of various etiologies. The diagnostic criteria for MD have undergone changes during the past few decades. A recent collaboration among specialty societies in United States, Europe and Japan has given rise to a new set of guidelines for the diagnosis and classification of MD. The aim is to develop international consensus criteria for MD that would help improve the quality of data collected from patients. The diagnosis of MD can be difficult in some cases as there is no gold standard for testing. Previous use of audiometric data and electrocochleography are poorly sensitive as screening tools. Recently magnetic resonance imaging as a diagnostic tool for identifying EH has gained popularity in Asia and Europe. Vestibular evoked myogenic potentials are also used but lack specificity. Finally, the treatment for MD has improved with the introduction of intratympanic treatments with steroids and gentamicin as well as less invasive treatment with the Meniett device.

Diagnosis and management of laryngeal cleft: A single centre experience and a novel endoscopic technique

AIM: To examine the presentation, diagnosis and outcomes of patients with laryngeal cleft.

METHODS: An 18 mo (from mid-2012 to 2013) prospective longitudinal study was performed at the Barts Children’s and Royal London Hospital, a tertiary referral centre. Chart review was performed for all patients including data extraction of demographics, outpatient clinic review documentation, speech therapy findings, medication list, operative findings alongside technique and follow up. A systematic review of contemporary English medical literature was also reviewed to compare series. The study was approved and registered by the hospital clinical governance and audit board. Biostatistician review was not required.

RESULTS: Twenty-two children aged 1 to 72 mo (mean age 23.5 mo) with a 7:4 male-female ratio. Twenty had Benjamin-Evans type 1 clefts and 2 had a type 2 cleft. All were symptomatic despite medical management including anti-reflux therapy. Patients presented with dyspnoea (81%), feeding difficulty (63%), stridor (54%) and recurrent pneumonia (36%). Several patients had concomitant aerodigestive abnormalities including 7 with laryngomalacia, 4 subglottic stenosis, 2 subglottic webs and 1 tracheo-oesophageal fistula. To date, 18 patients have undergone endoscopic repair, all of whom have shown radiological and/or clinical signs of improvement. All endoscopic repairs were performed with the novel use of a Negus knot pusher, with Baby Benjamin rigid suspension, to more reliably and easily suture at depth.

CONCLUSION: This is a significant single unit series demonstrating the strong association of laryngeal cleft with combined aerodigestive symptoms and other laryngeal abnormalities. Endoscopic management of type 1 and 2 laryngeal clefts is successful. We recommend the use of a Negus knot pusher to facilitate endoscopic repair.

Management of post-operative fistula in head and neck surgery: Sweeping it under the carpet?

The most dreaded complication in head and neck surgery is the development of fistula. Fistulas are common and devastating. The prevalence and the risk factors that contribute to fistula formation after head and neck procedures were discussed briefly. The main goal of this manuscript is to discuss current management of head and neck fistula. We believed that the best management strategy for head and neck fistulas is prevention. We recommend a holistic preventive approach during the perioperative period. The roles of different types of wound products and hyperbaric oxygen therapy were also discussed and highlighted. We also discussed the operative repair of fistulas, which relies on the tenet of providing well-vascularized tissue to an area of poor wound healing. Most often, the surgeon’s preference and range of operative skills dictate the timing and the type of repair. We highlighted the use of the pectoralis major, a well-known flap, as well as a novel technique in the surgical repair of complex, difficult-to-heal head and neck fistula.

Morbus Menière: Were the last 50 years of molecular biological research fruitless for Menière’s disease?

After discovering an inner ear hemorrhage, Prosper Menière ascribed disease to the inner ear for the first time. Since that time, a lot of efforts have been made to determine the pathophysiologic causes of the classical symptoms sensorineural hearing loss, vertigo attacks, tinnitus and ear fullness. According to its express pattern Menière’s disease may appear as classical and atypical disease. In the last decades, huge advances have taken place in biochemical and physiological research and in pathophysiological understanding of the inner ear and its diseases. This encloses stimulus perception and conduction, regulation of inner-ear fluid homeostasis and inner ear diseases with underlying genetics. Menière’s disease pathophysiologic correlate is an endolymphatic hydrops which is characterized by changes of inner ear homeostasis with its parameters volume, concentration, osmolarity and pressure of the endolymph. Hormones, autonomous system and the immunsystem together with purinergic, adrenergic and muscarinic receptors, steroids, vasopressin, atrial natriuretic peptide and aquaporin channels regulate inner ear homeostasis. Consequently, general diagnostics comprise a magnetic resonance imaging with gadolinium, vestibular diagnostics and tone audiometry. Standard therapy for acute inner ear symptoms is limited to cortisone infusions together with a rheologic agent or a radical scavenger. For acute vertigo attacks and for the mainstay therapy antivertiginous pharmaceuticals are given. In severe cases destruction of the vestibular hair cells by ototoxic antibiotics, endolymphatic sac surgery or neurectomy of the vestibular nerve might be necessary. Certainly, in research there is a move from simple pharmaceutical therapy forward to nanoparticle-based, genetic-based and stem cell therapy.

Thyroid lymphoma: A case report and literature review

Thyroid lymphoma is an unusual pathology. Different subtypes of lymphoma can present as primary thyroid lymphoma. This review illustrates via imaging, findings and treatment the need for accurate diagnosis and timely treatment. Patients and methods: patient’s chart, pathological findings and radiological images were reviewed in a retrospective analysis. Over several days, this 80 years old woman developed airway obstruction and rapid enlargement of her thyroid secondary to diffuse large B-cell lymphoma. She rapidly responded to her oncological protocol. Primary thyroid lymphoma is a rare disease. It is an important diagnosis to consider in patients presenting with rapidly enlarging neck masses. It is a treatable condition with fairly favorable overall survival even with the most aggressive histological subtypes.

Tongue dysfunction in neurological and neuromuscular disorders: A narrative literature review

Evaluation of oral function is useful for tracking longitudinal changes in swallowing function. Using videofluoroscopic (VF) images, we can evaluate swallowing function, but it is extremely difficult to quantitatively evaluate the oral phase. Recently, several studies have tried to quantitatively assess tongue function by analyzing tongue movement on VF images, to measure tongue thickness by ultrasonography, and to measure tongue pressure as surrogate for tongue strength. In this review article, the current state of quantitative assessments of tongue function for identification and management of dysphagia in patients with neuromuscular and other neurological disorders (NNMD) has been outlined. Disturbed bolus transport in patients with NNMD has been quantitatively measured on VF images by analyzing tongue base movement and bolus transport from the mouth to the pharynx. Enlarged tongue in Duchenne muscular dystrophy patients were observed by measuring the transverse width of the tongue on ultrasound. Tongue pressures that were measured using a handheld probe in NNMD patients were less than half of those in healthy subjects. More studies are needed to develop guidelines what types of tongue dysfunction give an indication of adjusting diet and introducing tube feeding to NNMD patients.

Diagnosis and treatment of sudden sensorineural hearing loss

Nationwide epidemiological surveys of idiopathic sudden sensorineural hearing loss (SSNHL) have been performed five times by the Research Committee of the Ministry of Health and Welfare or the Ministry of Health, Welfare and Labour in Japan. These surveys included patients who had SSNHL in 1972, 1987, 1993, 2001, and 2012. Using the criteria for the grading of hearing loss in SSNHL or the criteria for grading the degree of hearing recovery after SSNHL established by the Research Committee, we compared the outcomes of SSNHL between the five nationwide surveys. The results revealed that the outcomes of SSNHL have not changed in the past 40 years. In 1972, 88% of patients received steroids, but none received prostaglandin E₁ (PGE₁). The use of PGE₁ has increased since the 1980s, but its effect on SSNHL may not be significant. Intratympanic steroid injection has been introduced recently for the treatment of SSNHL, but it does not seem to be used widely in Japan. Intratympanic therapy that can reduce the total amount of steroids administered will be used more frequently if the true effects and indications for this therapy are known. Elucidation of the etiologies of SSNHL and development of treatments specific for these etiologies are expected.
