Treatment of the neck in residual/recurrent disease after chemoradiotherapy for advanced primary laryngeal cancer.

Concomitant chemoradiotherapy (CRT) is extensively used as primary organ preservation treatment for selected advanced laryngeal squamous cell carcinomas (LSCC). The oncologic outcomes of such regimens are comparable to those of total laryngectomy followed by adjuvant radiotherapy. However, the management of loco-regional recurrences after CRT remains a challenge, with salvage total laryngectomy being the only curative option. Furthermore, the decision whether to perform an elective neck dissection (END) in patients with rN0 necks, and the extent of the neck dissection in patients with rN + necks is still, a matter of debate. For rN0 patients, meta-analyses have reported occult metastasis rates ranging from 0 to 31 %, but no survival advantage for END. In addition, meta-analyses also showed a higher incidence of complications in patients who received an END. Therefore, END is not routinely recommended in addition to salvage laryngectomy. Although some evidence suggests a potential role of END for supraglottic and locally advanced cases, the decision to perform END should weigh benefits against potential complications. In rN + patients, several studies suggested that selective neck dissection (SND) is oncologically safe for patients with specific conditions: when lymph node metastases are not fixed and are absent at level IV or V. Super-selective neck dissection (SSND) may be an option when nodes are confined to one level. In conclusion, current evidence suggests that in rN0 necks routine END is not necessary and that in rN + necks with limited nodal recurrences SND or a SSND could be sufficient.

Tracheotomy versus tracheostomy, the need for lexicographical clarification.

In the healthcare field, the terms "traqueotomía" and "traqueostomía" are frequently used, often leading to confusion among professionals regarding the appropriate definition for each term or which one should be considered more correct in specific cases. A search was conducted for the terms "traqueotomía" and "traqueostomía" in general Spanish-language dictionaries such as the Dictionary of the Royal Spanish Academy (DRAE) and the Historical Dictionary of the Spanish Language of the Royal Spanish Academy (DHLE), as well as for the English terms "tracheotomy" and "tracheostomy" in English general dictionaries like the Oxford Dictionary, the Cambridge Dictionary, and the Collins English Dictionary. Additionally, searches were performed in medical dictionaries in both Spanish, specifically the Dictionary of Medical Terms of the National Academy of Medicine (DTM), and English, including the Farlex Dictionary. The terms were also explored using the Google search engine. Definitions were analyzed from both lexicographical and etymological perspectives. Definitions found in general dictionaries, in both Spanish and English, were found to be imprecise, limited, and ambiguous, as they mixed outdated indications with criteria that deviated from etymology. In contrast, definitions in medical dictionaries in both languages were more aligned with etymology. "Traqueotomía" strictly identifies the surgical procedure of creating an opening in the anterior face of the trachea. "Traqueostomía" identifies the creation of an opening that connects the trachea to the exterior, involving a modification of the upper airway by providing an additional entry for the respiratory pathway. "Traqueostomía" becomes the sole means of entry to the airway in total laryngectomies. Both terms can be used synonymously when a traqueotomía culminates in a traqueostomía. However, it is not appropriate to use the term "traqueostomía" when the procedure concludes with the closure of the planes and does not result in the creation of a stoma. Traqueostomas can be qualified with adjectives indicating permanence (temporary/permanent), size (large/small), shape (round/elliptical), or depth, without being linked to any specific disease or surgical indication. Not all permanent traqueostomas are the result of total laryngectomies, and they do not necessarily have an irreversible character systematically.

Evaluation of Intima-Media Thickness and Arterial Stiffness as Early Ultrasound Biomarkers of Carotid Artery Atherosclerosis.

Carotid atherosclerosis is a major and potentially preventable cause of ischemic stroke. It begins early in life and progresses silently over the years. Identification of individuals with subclinical atherosclerosis is needed to initiate early aggressive vascular prevention. Although carotid plaque appears to be a powerful predictor of cardiovascular risk, carotid intima-media thickness (CIMT) and arterial stiffness can be detected at the initial phases and, therefore, they are considered important new biomarkers of carotid atherosclerosis. There is a well-documented association between CIMT and cerebrovascular events. CIMT provides a reliable marker in young people, in whom plaque formation or calcification is not established. However, the usefulness of CIMT measurement in the improvement of risk cardiovascular models is still controversial. Carotid stiffness is also significantly associated with ischemic stroke. Carotid stiffness adds value to the existing risk prediction based on Framingham risk factors, particularly individuals at intermediate cardiovascular risk. Carotid ultrasound is used to assess carotid atherosclerosis. During the last decade, automated techniques for sophisticated analysis of vascular mechanics have evolved, such as speckle tracking, and new methods based on deep learning have been proposed with promising outcomes. Additional research is needed to investigate the imaging-based cardiovascular risk prediction of CIMT and stiffness.

[Consensus document of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units (SEMICYUC), the Spanish Society of Otorhinolaryngology and Head and Neck Surgery (SEORL-CCC) and the Spanish Society of Anesthesiology and Resuscitation (SEDAR) on tracheotomy in patients with COVID-19 infection]. / Documento de consenso de la Sociedad Española de Medicina Intensiva, Crítica, y Unidades Coronarias (SEMICYUC), la Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello (SEORL-CCC) y la Sociedad Española de Anestesiología y Reanimación (SEDAR) sobre la traqueotomía en pacientes con COVID-19.

The current COVID-19 pandemic has rendered up to 15% of patients under mechanical ventilation. Because the subsequent tracheotomy is a frequent procedure, the three societies mostly involved (SEMICYUC, SEDAR and SEORL-CCC) have setup a consensus paper that offers an overview about indications and contraindications of tracheotomy, be it by puncture or open, clarifying its respective advantages and enumerating the ideal conditions under which they should be performed, as well as the necessary steps. Regular and emergency situations are displayed together with the postoperative measures.

PD-L1 expression correlates with tumor-infiltrating lymphocytes and better prognosis in patients with HPV-negative head and neck squamous cell carcinomas.

INTRODUCTION: The importance of immune tumor microenvironment in the prognosis of patients with head and neck squamous carcinomas (HNSCC) is increasingly recognized. We analyzed the prognostic relevance of PD-L1 and PD-1 expressions in relation to the infiltration by CD8+ and FOXP3+ tumor-infiltrating lymphocytes (TILs). METHODS: Samples from 372 surgically treated HPV-negative HNSCC patients were evaluated by immunohistochemistry for PD-L1 expression [both tumor proportion score (TPS) and combined proportion score (CPS)], PD-1 expression in immune cells, and density of infiltrating CD8+ and FOXP3+ TILs. PD-L1 expression and CD8+ TIL density were combined to establish the type of tumor microenvironment. RESULTS: 29.5% cases exhibited PD-L1 TPS positivity (≥ 1%), whereas PD-L1 CPS positivity (≥ 1%) was observed in 40% cases. 47.5% cases showed positive PD-1 expression (≥ 1%). PD-L1 and PD-1 positivity correlated with a high density of both CD8+ and FOXP3+ TILs. In univariate analysis, PD-L1 TPS positivity (P = 0.026), PD-L1 CPS positivity (P = 0.004), high density of CD8+ TIL (P = 0.001), and high density of FOXP3+ TIL (P = 0.004) were associated with a better disease-specific survival (DSS). However, in multivariate analysis, only high density of CD8+ TIL was associated with a better DSS (P = 0.002). The type of tumor microenvironment correlated with DSS (P = .008), with the better DSS observed in cases with type I (PD-L1 CPS positivity and high density of CD8+ TIL). CONCLUSIONS: High infiltration by CD8+ TIL is associated with better survival outcomes. Positive PD-L1 expression correlates with a high infiltration by TILs, explaining its association with better prognosis.

Recommendations of the Spanish Society of Otolaryngology and Head and Neck Surgery for performing tracheotomies in patients infected by the coronavirus, Covid-19. / Recomendaciones de la Sociedad Española de Otorrinolaringología y Cirugía de Cabeza y Cuello para la realización de traqueotomías en relación con pacientes infectados por coronavirus COVID-19.

The recent COVID-19 (coronavirus) pandemic is causing an increase in the number of patients who, due to their pulmonary ventilatory status, may require orotracheal intubation. COVID-19 infection has demonstrated a high rate of transmissibility, especially via the respiratory tract and by droplet spread. The Spanish Society of Otolaryngology and Head and Neck Surgery, based on the article by Wei et al. of 2003 regarding tracheotomies performed due to severe acute respiratory syndrome (SARS), has made a series of recommendations for the safe performance of tracheotomies.

Results of total laryngectomy as treatment for locally advanced hypopharyngeal cancer. / Resultados de la laringectomía total en carcinomas localmente avanzados de hipofaringe.

INTRODUCTION AND OBJECTIVES: Total laryngectomy (TL), with eventual postoperative radiotherapy, has proven to be effective in treating cases of locally advanced hypopharyngeal cancer. The aim of this study was to analyse the oncological outcomes of this procedure in patients with hypopharyngeal cancer classified T3 and T4. METHODS: We studied 59 patients (33 T3 and 26 T4a) with primary squamous cell carcinoma of the hypopharynx treated with TL from 1998 to 2012. RESULTS: Mean age was 61 years with a male predominance (96.6%). All the patients were smokers and 96% consumed alcohol. Unilateral selective neck dissection (ND) was performed in 12 patients, unilateral radical ND in 11 patients, bilateral selective ND in 20 patients and radical ND plus selective ND in 14 patients. 66% of the patients received postoperative radiotherapy. Lymph node metastases occurred in 81% of the patients and extranodal invasion in 56% of them. 29% of the patients had loco-regional recurrence, 17% developed distant metastases, and 25% a second primary tumour. The 5-year disease-specific survival was 46%. CONCLUSIONS: TL extended to pharynx (with eventual postoperative radiotherapy) offers good oncological results in terms of loco-regional control and survival in locally advanced hypopharyngeal cancer, so organ preservation protocols should achieve similar oncological results to those shown by TL.

Treatment of the first bite syndrome. / Tratamiento con toxina botulínica del síndrome del primer mordisco.

First bite syndrome is a potential complication of surgery involving the infratemporal fossa, deep lobe of the parotid gland and parapharyngeal space. It is described as an acute and intense pain in the parotid region caused with the first bite of each meal. It is related to damage to sympathetic innervation of the parotid gland. Parasympathetic hyperactivation is believed to stimulate an exaggerated myoepithelial cell contraction causing pain. Usual analgesic treatments have poor results. Botulinum toxin type A causes parasympathetic nerve paralysis of the parotid gland and this fact would minimize salivation and decrease first bite syndrome. The aim of this study is to show the details of the technique and our outcomes in 5 patients treated with botulinum toxin type A.

Schwannoma of the larynx. An infrequent laryngeal tumour.

Schwannomas are benign tumours, rare among tumours of the larynx. They normally present as supraglottic masses (because they may arise from the internal branch of the superior laryngeal nerve), most commonly involving aryepiglottic folds or false vocal folds. Most patients present with a globus sensation, dysphagia or hoarseness. Conservative surgery is the treatment of choice. We report a case of a laryngeal asymptomatic neuroma that was diagnosed accidentally in an imaging test. Complete excision of the tumour was performed through a transoral CO2 laser microsurgery without resorting to a tracheotomy. We discuss the clinical, pathologic and imaging findings and the management of this neoplasm. We also try to update the knowledge on the management of these tumours.

[Peritonsillar infections: prospective study of 100 consecutive cases]. / Infecciones periamigdalinas: estudio prospectivo de 100 casos consecutivos.

INTRODUCTION: Peritonsillar infection is the most frequent complication of acute tonsillitis. Peritonsillar infections are collections of purulent material, usually located between the tonsillar capsule and the superior constrictor of the pharynx. Peritonsillar infection can be divided into abscess and cellulitis. MATERIAL AND METHODS: We prospectively analysed the clinical data from 100 patients with peritonsillar infection from 2008 to 2010. The diagnosis of abscess or peritonsillar cellulitis was primarily based on obtaining pus through fine-needle aspiration. RESULTS: Seventy-seven per cent of patients had no history of recurrent tonsillitis and 55% were receiving antibiotic treatment. Sixty-two cases were peritonsillar abscess and the rest were cellulitis. Trismus, uvular deviation and anterior pillar bulging were statistically associated with peritonsillar abscess (P<.005). All patients were admitted to hospital and treated with puncture-drainage, intravenous antibiotics (amoxicillin/clavulanate in 83% of cases) and a single dose of steroids. All patients were discharged on oral antibiotic therapy. The mean length of hospital stay was 3 days and the recurrence rate was 5%. CONCLUSIONS: Due to the absence of clinical practice guidelines, there are different therapeutic protocols. According to our experience, puncture-aspiration and administration of intravenous antibiotics is a safe, effective way to treat these patients. To determine the efficacy and safety of outpatient management, controlled studies would be needed.

Unilateral agenesis of the internal carotid artery.

Unilateral agenesis of the internal carotid artery (ICA) is an extremely rare anomaly. Diagnosis is often incidental in a radiological examination. Recognition of this anomaly has important clinical implications because other life-threatening conditions can be associated and it must be taken into account when planning carotid surgery. We report a case of 64-year-old man with agenesis of the ICA.

[Neck mass with infrequent origin]. / Masa cervical de origen infrecuente.

We report the case of a 67-year-old male diagnosed with prostate adenocarcinoma, who referred dysphagia, dysphonia and noticed the appearance of a laterocervical mass. A CT scan revealed an osteolytic soft tissue neck lesion, which was resected. Its anatomical-pathological study was compatible with metastasis of prostate adenocarcinoma.

[Transoral laser microsurgery in advanced carcinomas of larynx and pharynx]. / Cirugía transoral LASER CO2 en tumores avanzados de faringe y laringe.

INTRODUCTION AND OBJECTIVES: There are several types of treatment for advanced squamous cell carcinomas of the pharynx and larynx. However, both open surgery and chemoradiation protocols have failed to improve control and survival. There is a tendency toward conservative treatment without worsening oncological outcomes. The objective of this study was to describe the effectiveness of organ-preserving CO2 laser microsurgery for treating advanced carcinomas of the larynx and pharynx. MATERIAL AND METHOD: A retrospective review of 63 patients undergoing CO2 laser microsurgery for the treatment of squamous cell carcinomas of the pharynx and larynx in advanced stages (stages III and IV) was performed. Tumour distribution was 14 patients with a tumour at the base of the tongue, 16 with a pyriform sinus tumour, 29 with a supraglottic tumour and 4 with a glottic tumour. Mean follow-up was 51 months. RESULTS: Thirty-five percent of patients (23) had recurrences. The recurrence rate was 28% for base of tongue tumours, 50% for hypopharyngeal tumours, 27% for supraglottic tumours and 75% for glottic tumours. The 5-year disease-specific survival rate was 73.3% for all locations, with a range from 90% for supraglottic tumours up to 50% for glottic tumours. Thirty-four percent of patients had some type of complication after surgery. The most frequent complication was local bleeding (17%). CONCLUSION: Transoral CO2 laser microsurgery is an alternative for the treatment of carcinomas of the pharynx and larynx in advanced stages. Its oncological results are equivalent to other treatment modalities and its morbidity is lower.

Malignant triton tumor of the infratemporal fossa.

Malignant triton tumor is a very aggressive type of sarcoma that comprises rhabdomyoblasts and malignant Schwann cells. It is a different entity from malignant schwannoma, characterized by their aggressiveness and poor prognosis. Head and neck location is frequent, and early diagnosis and complete resection followed by radiation therapy is important for long-term survival. However, the therapeutic plan should be individualized, taking into account the location and size of the primary tumor. The use of adjuvant chemotherapy and molecular therapies should be considered in the treatment of these tumors. We report an unusual presentation of a malignant triton tumor located in the infratemporal fossa, describing its clinical and pathologic features, and we try to update the knowledge in the management of these tumors, including the use of molecular therapies.

[Primary tumours of the parapharyngeal space. Our experience in 51 patients]. / Tumores primarios del espacio parafaríngeo. Nuestra experiencia en 51 pacientes.

INTRODUCTION AND OBJECTIVES: Tumours of the parapharyngeal space are rare, representing only 0.5 % of head and neck oncology. The aim of this study is to present our experience with the diagnosis and therapies for these tumours. PATIENTS AND METHOD: This study is a retrospective review of 51 patients diagnosed as having tumours of the parapharyngeal space and treated surgically between 1984 and 2006. Tumours originating in the deep lobe of parotid gland were excluded. RESULTS: Seventy percent of the parapharyngeal space neoplasms were benign and thirty percent malignant. Pleomorphic adenoma was the most common neoplasm (37 %), followed by miscellaneous benign tumours (34 %), paraganglioma (21 %), and neurogenic tumours (8 %). Surgery was chosen in all case, with the transcervical approach used in 32 cases, the cervical-transparotid approach in 13 cases, the transmandibular approach in 4 cases (with mandibulectomy in 1 patient), the transoral approach in 1 case, and the infratemporal fossa approach in 1 case. The most common complications were those deriving from damage to nerve structures. CONCLUSIONS: Most parapharyngeal space tumours can be removed surgically with a low rate of complications and recurrence. The transcervical approach is the most frequently used.
