Request AccessThe mechanism of action for laryngeal manual therapies: the need for an update.
Mouth, Head and NeckTo propose a pathway for expanding the understanding of potential mechanisms of action with laryngeal-based manual therapy (LMT) for muscle tension dysphonia (MTD). This review may help determine if current LMT literature has kept up with advances in the more general manual therapy (MT) findings.
Studies over the past thirty years, including recently published articles, have confirmed the efficacy of various manual therapy interventions in treating MTD. However, gaps exist between current LMT literature and that being presented in the more general MT field. Instead of viewing peripheral manipulation's influences as a local cause/effect process, the MT literature paints a richer tapestry of centrally mediated impacts.
Evidence from outside the LMT field has introduced a broad tapestry of factors that may contribute to the efficacy of MT, extending beyond the local effects reported in LMT literature. To better understand the effect and mechanism of action touch-based interventions have on a patient's voice and to potentially improve outcomes, it is necessary to broaden investigations to include a broader range of perspectives.
Managing lymphoedema following treatment for head and neck cancer: is complete decongestive therapy an effective intervention to improve dysphagia outcomes?
Mouth, Head and NeckThe purpose of this review is to summarize current evidence regarding management of head and neck lymphoedema (HNL) to improve dysphagia outcomes following head and neck cancer (HNC) treatment. This review aims to support complete decongestive therapy (CDT) comprising compression, manual lymphatic drainage (MLD), exercises and skincare as an adjunct of dysphagia rehabilitation.
Research in the limbs supports the use of CDT to improve lymphoedema outcomes. Emerging evidence supports the use of CDT for the head and neck, though, there is no consensus on optimal treatment required to improve dysphagia outcomes. Current evidence is limited due to a paucity of randomized controlled trials, case series or cohort studies with small participant numbers, and a lack of functional and instrumental dysphagia outcome measures. This provides a foundation to design and test an individually tailored programme of HNL intervention to evaluate swallowing outcomes post CDT.
As the incidence of HNC is increasing with HPV, with patients living for longer with late effects of HNC treatment, it is vital to understand how the presence of HNL impacts on the swallow, and if functional dysphagia outcomes improve following treatment of HNL. Prospective, longitudinal research with objective and functional outcome measures are required to help determine optimal management of HNL and its impact on the swallow.
Current approaches to gender-affirming vocal care.
Mouth, Head and NeckThis review addresses the challenges faced by transgender women in achieving congruence between gender identity and voice characteristics and emphasises the importance of a multidisciplinary approach involving therapeutic and surgical interventions.
Recent literature on gender-affirming vocal care emphasises key themes such as assessment, voice feminisation therapy, and various surgical techniques, including glottoplasty and its modifications. Recent publications focused on outcomes, duration, and impact on vocal quality and scrutinised complications associated with surgical interventions.
Prospective multicentre studies with standardised protocols are needed to establish best evidence-based practices.
Managing massive palatial defect secondary to palatoplasty failures: an in-depth analysis.
Mouth, Head and NeckMassive palatal defects resulting from palatoplasty failures arising from cleft palate repair complications present ongoing challenges in clinical practice. The purpose of this review is to provide up-to-date insights into aetiology, risk factors, surgical techniques, and adjunctive therapies, aiming to enhance the understanding of such complex cases, and optimize patient outcomes.
Primary palatoplasty has fistula recurrence rates ranging from 2.4% to 55%. Factors such as cleft width, surgical repair method, and patient characteristics, influence the likelihood of failure. Classifications such as the Pakistan Comprehensive Classification and Richardson's criteria aid in assessing defects. Surgical options range from local flaps and revision palatoplasty to regional flaps (e.g., buccinator myomucosal, facial artery-based flaps, tongue flaps, nasal septal flaps) to free microvascular flaps. Alternative approaches include obturator prostheses, and acellular dermal matrix has been used as an adjuvant to multiple repair techniques. Hyperbaric oxygen therapy has emerged as an adjunctive therapy to enhance tissue healing.
This comprehensive review underscores the intricate challenges associated with massive palatal defects resulting from palatoplasty failures. The diverse range of surgical and nonsurgical options emphasizes the importance of patient-centric, individualized approaches. Practitioners, armed with evidence-based insights, can navigate these complexities, offering tailored interventions for improved patient outcomes.
'Seeing is believing' - gender disparities in otolaryngology-head and neck surgery in Africa: a narrative review.
Mouth, Head and NeckVarious factors affect otolaryngology - head and neck surgery (OHNS) services in low- and middle-income countries (LMICs); including inadequate infrastructure, limited academic positions, unfavorable hospital research policies, and traditional misconceptions about gender and surgery, among others. Although gender inequalities exist globally, they are particularly pronounced in LMICs, especially in Africa.
A comparative narrative literature review for relevant manuscripts from January 1, 2017 to through January 10th, 2024, using PubMed, Embase and Google Scholar for articles from the United States/Canada and Africa was done. 195 relevant articles were from the United States/Canada, while only 5 were from Africa and only 1 manuscript was relevant to OHNS. The reviewed articles reported that gender disparities exist in medical training, authorship, and career advancement. We highlight possible solutions to some of these disparities to promote a more gender-diversified workforce in OHNS in Africa as well as all over the world.
Additional studies on gender disparities in Africa, are needed. These studies will highlight need for inclusive policies, structured and accessible mentorship programs; through which these disparities can be highlighted and addressed. This will in the long run ensure sustainability of OHNS care in LMICs.
The added value of radiomics in determining patient responsiveness to laryngeal preservation strategies.
Mouth, Head and NeckLaryngeal cancer (LC) is a highly aggressive malignancy of the head and neck and represents about 1-2% of cancer worldwide.Treatment strategies for LC aim both to complete cancer removal and to preserve laryngeal function or maximize larynx retention.Predicting with high precision response to induction chemotherapy (IC) is one of the main fields of research when considering LC, since this could guide treatment strategies in locally advanced LC.
Radiomics is a noninvasive method to extract quantitative data from the whole tumor using medical imaging. This signature could represent the underlying tumor heterogeneity and phenotype.During the last five years, some studies have highlighted the potential of radiomics in the pretreatment assessment of LC, in the prediction of response to IC, and in the early assessment of response to radiation therapy. Although these represent promising results, larger multicentric studies are demanded to validate the value of radiomics in this field.
The role of radiomics in laryngeal preservation strategies is still to be defined. There are some early promising studies, but the lack of validation and larger multicentric studies limit the value of the papers published in the literature and its application in clinical practice.
Compartmental surgery for T4b oral squamous cell carcinoma involving the masticatory space.
Mouth, Head and NeckThis review aims to describe the oncological outcomes of T4b oral squamous cell carcinomas (OSCC) with masticatory space involvement as well as the surgical approaches that are able to achieve compartmental 'en bloc' resection of these lesions.
The masticatory space is subdivided into infra-notch and supra-notch spaces according to the axial plane passing through the mandibular notch between the coronoid process and the condyle neck. Compartmental resection for T4b OSCC with masticatory space invasion can be successfully achieved via purely external approaches or combining external and transnasal endoscopic routes. Infra-notch T4b OSCC showed survival outcomes comparable to T4a OSCC, thus prompting treatment with curative intent.
Compartmental resection of the masticatory space is technically feasible with comprehensive control of tumour margins. Use of a transnasal endoscopic anterior route within a multiportal approach may provide better control of margins at the level of the pterygo-maxillary fissure. Equivalent survival outcomes between T4a and infra-notch T4b OSCC are reported. Thus, a downstaging of the latter to T4a is advisable and compartmental surgery of such advanced lesions could be considered as a first-line treatment option in selected patients.
Neurosurgery for the rhinologist.
Mouth, Head and NeckThe purpose of this review is to provide a comprehensive anatomical appraisal of the neurosurgical anatomy exposed through the endonasal and paranasal sinuses routes, focusing on the most common expanded endonasal approaches (EEAs) as well as recent advances in this surgical field.
The EEAs are redefining the management of skull base pathology. Neurovascular structures previously considered a limitation, can be now approached through these surgical corridors. Advances in this field include the development of new surgical techniques and routes that allow better visualization and access to pathologies located in the ventral skull base. Understanding the surgical anatomy related to EEAs is essential not only for neurosurgeons but also for rhinologists.
Knowledge of the surgical anatomy of the most common EEAs that utilize paranasal sinuses as a surgical corridor enables more effective management of complex skull base pathologies. Comprehensive anatomical knowledge of these corridors and the surrounding neurovascular structures is crucial to maximize benefits of EEAs and improve outcomes.
A stepwise approach to the adult immunodeficiency evaluation for the rhinologist.
Mouth, Head and NeckPatients with an immunodeficiency may present to their Rhinologist with a history of recurrent, severe, and chronic infections. Therefore, it is essential for the Rhinologist to have a basic understanding of clinically relevant immune deficiencies.
After describing different types of immunodeficiencies, their presentations, and management strategies, an evaluation algorithm is described.
Through a collaborative approach, Rhinologists and Clinical Immunologists can provide comprehensive medical care to patients with immunodeficiencies.
Hyperspectral imaging and evaluation of surgical margins: where do we stand?
Mouth, Head and NeckTo highlight the recent literature on the use of hyperspectral imaging (HSI) for cancer margin evaluation ex vivo, for head and neck cancer pathology and in vivo during head and neck cancer surgery.
HSI can be used ex vivo on unstained and stained tissue sections to analyze head and neck tissue and tumor cells in combination with machine learning approaches to analyze head and neck cancer cell characteristics and to discriminate the tumor border from normal tissue. Data on in vivo applications during head and neck cancer surgery are preliminary and limited. Even now an accuracy of 80% for tumor versus nonneoplastic tissue classification can be achieved for certain tasks, within the current in vivo settings.
Significant progress has been made to introduce HSI for ex vivo head and neck cancer pathology evaluation and for an intraoperative use to define the tumor margins. To optimize the accuracy for in vivo use, larger HSI databases with annotations for head and neck cancer are needed.
Temporal bone management in external and middle ear carcinoma.
Mouth, Head and NeckThe purpose of this review is to outline the temporal bone management of external and middle ear carcinoma. The review will outline the current evidence involved in deciding which surgical approach to take, as well as new advances in auditory rehabilitation and immunotherapy.
Traditional surgical approaches include lateral temporal bone resection, subtotal temporal bone resection and total temporal bone resection. They can also involve parotidectomy and neck dissection depending on extension of disease into these areas. Options for auditory rehabilitation include osseointegrated hearing aids, transcutaneous bone-conduction implants, and active middle ear implants. Recent advances in immunotherapy have included the use of anti-PD-1 monoclonal antibodies.
The mainstay of management of temporal bone disease involves surgical resection. Early-stage tumours classified according to the Pittsburgh staging tool can often be treated with lateral temporal bone resection, whereas late-stage tumours might need subtotal or total temporal bone resection. Parotidectomy and neck dissection might also be indicated if there is a risk of occult regional disease. Recent advances in immunotherapy have been promising, particularly around anti-PD-1 inhibitors. However, larger clinical trials will be required to test the extent of efficacy, particularly around combination use with surgery.
Head and neck nonmelanoma skin cancers: surgical management and debated issues.
Mouth, Head and NeckThis review critically assesses the current literature and guidelines, aiming to clarify some of the most important factors that impact surgical strategies of head and neck nonmelanoma skin cancers (NMSCs), focusing on squamous, basal, and Merkel cell carcinomas.
Recent developments underscore the complexity of treatment for NMSC, particularly in the head and neck region. There is a lack of high-level evidence for the management of these tumors, especially in advanced stages. The need to tailor the extent of surgical margins and parotid/neck management to different histotypes, considering the varying risk factors for recurrence, is beginning to emerge in the literature. Moreover, the role of immunotherapy and targeted therapies for locally advanced disease, alongside traditional treatment options, is progressively growing.
NMSCs represent a heterogeneous group of malignancies with varying treatment complexities and prognoses. Management of NMSC is evolving towards an increasingly personalized strategy within a multidisciplinary therapeutic framework.
