Lateral neck cyst surgery without ipsilateral tonsillectomy: a retrospective analysis.

PURPOSE: Several theories have been proposed regarding the origin of lateral neck cysts (LNC). Besides complete surgical resection ipsilateral tonsillectomy and dissection of a tract or its remnants is sometimes recommended. In this retrospective trial we wanted to evaluate if patients, who received LNC resection only, develop complications or recurrence to justify this surgical strategy. METHODS: Patients who received LNC resection between 2004 and 2017 at the Ear Nose and Throat Department of a university hospital were included. Data was collected from the clinic database and through a structured telephone interview. RESULTS: A total of 126 patients met the inclusion criteria. In this collective, the diagnosis of a lateral neck cyst was confirmed histologically. Mean age at time of operation was 38 years (± 14.6). The median follow-up time was 7 years (range 3-18). None of the participants experienced recurrent unilateral pharyngitis or tonsillitis during follow-up. Furthermore, there was no case of postoperative peritonsillar, neck phlegmon or neck abscess. No patient reported recurrence of LNC. CONCLUSIONS: Sole complete resection of LNCs is sufficient to avoid postoperative infections and recurrences. Therefore, ipsilateral tonsillectomy and tract dissection is not necessary in routine cases of LNC surgery.

TIMolol Nasal Spray as a Treatment for Epistaxis in Hereditary Hemorrhagic Telangiectasia (TIM-HHT)-A Prospective, Randomized, Double-Blind, Controlled, Cross-Over Trial.

To date, there is no approved local therapeutic agent for the treatment of epistaxis due to hereditary hemorrhagic telangiectasia (HHT). Several case reports suggest the topical use of timolol. This monocentric, prospective, randomized, placebo-controlled, double-blinded, cross-over study investigated whether the effectiveness of the standard treatment with a pulsed diode laser can be increased by also using timolol nasal spray. The primary outcome was severity of epistaxis after three months, while the main secondary outcome was severity of epistaxis and subjective satisfaction after one month. Twenty patients were allocated and treated, of which 18 patients completed both 3-month treatment sequences. Timolol was well tolerated by all patients. Epistaxis Severity Score after three months, the primary outcome measure, showed a beneficial, but statistically nonsignificant (p = 0.084), effect of additional timolol application. Epistaxis Severity Score (p = 0.010) and patients' satisfaction with their nosebleeds after one month (p = 0.050) showed statistically significant benefits. This placebo-controlled, randomized trial provides some evidence that timolol nasal spray positively impacts epistaxis severity and subjective satisfaction in HHT patients when additively applied to standard laser therapy after one month. However, the effect of timolol was observed to diminish over time. Trials with larger sample sizes are warranted to confirm these findings.

HHT-Related Epistaxis and Pregnancy-A Retrospective Survey and Recommendations for Management from an Otorhinolaryngology Perspective.

Appropriate management of hereditary hemorrhagic telangiectasia (HHT) is of particular importance in females, as HHT-mediated modifications of the vascular bed and circulation are known to increase the risk of complications during pregnancy and delivery. This study was undertaken to evaluate female HHT patients' awareness of and experience with HHT during pregnancy and delivery, with a focus on epistaxis. In this retrospective study, 46 females (median age: 60 years) with confirmed HHT completed a 17-item questionnaire assessing knowledge of HHT and its pregnancy-associated complications, the severity of epistaxis during past pregnancies and deliveries, and the desire for better education and counselling regarding HHT and pregnancy. Results revealed that 85% of participants were unaware of their disease status prior to the completion of all pregnancies. Further, 91% reported no knowledge of increased pregnancy-related risk due to HHT. In regard to epistaxis, 61% of respondents reported experiencing nosebleeds during pregnancy. Finally, approximately a third of respondents suggested that receiving counseling on the risks of HHT in pregnancy could have been helpful. Findings suggest that awareness of HHT and its potential for increasing pregnancy-related risk is poor. Best practices in HHT management should be followed to minimize negative effects of the disorder.

Gustatory Function in Acute COVID-19 - Results From Home-Based Psychophysical Testing.

OBJECTIVE: Gustatory function during COVID-19 is self-reported by around 50% of patients. However, only a few studies assessed gustation using psychophysical testing during acute infection. The objective of this study is to test gustatory function on threshold tests in the very first days of COVID-19. METHODS: Psychophysical testing consisted of validated and blinded tests for olfaction (NHANES Pocket Smell Test) and gustation (Taste Strips Test). These test kits were sent to home-quarantined patients and self-administered using a detailed instruction sheet. RESULTS: A total of 51 patients were included in this study. Testing was performed 6.5 ± 2.7 days after sampling of respiratory swabs. At this time 37% of patients stated to currently experience a gustatory impairment. The mean Taste Strips score was 10.0 ± 3.4 with 28% scoring in the range of hypogeusia. Interestingly, no significant difference in the results of gustatory testing could be observed between the group with subjectively preserved gustation and the group with self-rated taste impairment. CONCLUSION: During the very first days of COVID-19, psychophysical gustatory testing revealed hypogeusia in 28%. This is far lower than patients' self-reports. Different from previous studies, we did not find clear evidence for an impairment of only certain taste qualities. LEVEL OF EVIDENCE: 3 Laryngoscope, 132:1082-1087, 2022.

Hereditary Hemorrhagic Telangiectasia: Success of the Osler Calendar for Documentation of Treatment and Course of Disease.

Hereditary hemorrhagic telangiectasia (HHT; Rendu-Osler-Weber syndrome) affects the capillary and larger vessels, leading to arteriovenous shunts. Epistaxis is the main symptom impairing quality of life. The aim of the Osler Calendar is to offer information about the extent of the systemic disease and the current state of treatment. A care plan with information on the rare disease and self-treatment of epistaxis was created. Organ examinations and ongoing treatments were recorded. A questionnaire documents the treatment success, including patient satisfaction, frequency of hemorrhage and hemoglobin levels. The patients using the Osler Calendar for at least one year (n = 54) were surveyed. Eighty-five percent of patients (n = 46) used the calendar to gain information about HHT. Seventy-two percent (n = 39) used the Osler Calendar for instructions on the self-treatment of nosebleeds. The calendar increased patients' understanding for the need for organ screenings from 48% (n = 26) to 81% (n = 44). Seventy-nine percent (n = 43) of patients confirmed that the Osler Calendar documented their therapeutic process either well or very well. Fifty-two percent (n = 28) saw an improvement in the therapeutic process due to the documentation. The Osler Calendar records the individual intensity of the disease and facilitates the communication between attending physicians. It is a tool for specialists to review treatment strategies. Furthermore, the calendar enhances patients' comprehension of their condition.

[Evaluation of oesophagoscopy for staging and restaging of head and neck squamous cell carcinoma]. / Evaluation der Ösophagoskopie im Staging und Restaging von Kopf-Hals-Plattenepithelkarzinomen.

OBJECTIVE: Oesophagoscopy is important in diagnostic and follow up investigation in patients with head and neck squamous cell carcinoma (HNSCC). Second primary malignancies of the oesophagus have major impact on therapy of the primary tumour. Considering the low incidence of oesophageal second primaries and the serious complication of oesophageal perforation routine oesophagoscopy is being discussed. MATERIAL AND METHODS: Incidence of oesophageal second primaries and complication rates in oesophagoscopy were identified in a systematic review. A retrospective analysis was performed in our own patient collective. To evaluate the current practice at German ENT Clinics a survey was conducted. RESULTS: 1053 oesophagoscopies in 800 patients were analysed. In 800 patients seven (0.9 %) synchronous secondary malignancies of the oesophagus occurred. In 253 follow up oesophagoscopies five (2 %) metachronous secondary malignancies were discovered. 14 (1.3 %) complications were detected; oesophageal perforation was only detected in one case (0.1 %). There was no association of certain risk factors with the incidence of secondary malignancies. The review of literature showed an incidence of secondary malignancies for Europe/USA of 1.8 % and for Asia of 4.1 %. Incidence of oesophageal perforation was 0-0.2 %. Survey results showed routine oesophagoscopy in staging (100 %) and regularly in follow up (65.3 %). CONCLUSIONS: Oesophagoscopy is a convenient method to detect secondary malignancies of the oesophagus. To allow a selection of patients developing secondary malignancies according to risk profiles further prospective multicentre studies are required.

[Diagnostic Criteria and Treatment of Hereditary Hemorrhagic Telangiectasia]. / Diagnostik und Behandlung der hereditären hämorrhagischen Teleangiektasie.

Hereditary hemorrhagic telangiectasia (HHT; Osler-Weber-Rendu syndrome; Morbus Osler) represents a syndrome affecting capillary vessels, leading to arteriovenous shunting. With an average worldwide prevalence of 1:5.000-8.000 HHT is considered an orphan disease. Arteriovenous shunts involve predominantly the nasal mucosa, the intestine, lung, liver and central nervous system. Epistaxis is the primary and most bothersome complaint of patients with HHT. A multistage therapeutic concept includes nasal ointment, laser therapy under local anesthesia and surgery under general anesthesia, as well as drug therapies. In addition, screening to determine affection of internal organs is carried out. Lesions that require therapy should be treated in an interdisciplinary setting. Treatment of lesions of the skin, oral and gastrointestinal mucosa and liver is carried out in regard to patients' symptoms, whereas vascular malformations of the lung and brain might need treatment without being symptomatic, due to possible life-threatening complications.

Identification of two distinct hereditary hemorrhagic telangiectasia patient subsets with different hepatic perfusion properties by combination of contrast-enhanced ultrasound (CEUS) with perfusion imaging quantification.

BACKGROUND: Hereditary hemorrhagic telangiectasia (HHT) is marked by arteriovenous fusion comprising hepatic vascular malformations (HVaMs) with the chance of bleeding. AIMS: We investigated HVaMs in HHT patients by combination of contrast-enhanced ultrasound (CEUS) with perfusion imaging quantification to be able to sub-classify a high risk cohort of asymptomatic HHT patients. METHODS: The imaging characteristics on CEUS in 34 patients (aged 21-84 years; mean 58.9) with HHT were retrospectively evaluated. Real-time contrast harmonic imaging, sulfur hexafluoride-filled microbubbles and motion adjustment were utilized. Cine loops of the liver were digital stored, perfusion was quantified using a software reading DICOM data`s. RESULTS: HVaMs were diagnosed in 31 out of 34 patients. Significant uppermost peak enhancement (PE), wash-in area under the curve (WiAUC) and wash-in perfusion index (WiPI) were identified in the shunt region (100%), next in the hilar region (PE 32.6%; WiAUC 33.9%; WiPI 34.1%), and the lowest in the hepatic parenchyma (PE 10.2%; WiAUC 12.0%; WiPI 9.5%). The perfusion parameters in the shunt region compared to the other regions were significantly increased in one subgroup of patients. Consistent with this, the intrahepatic portal vein diameter and Buscarini grading was significantly higher, while portal vein peak velocity was significantly lower in this patient subset. By statistical analysis, we could correlate PE and WiPI to these clinical parameters, while WiAUC showed no clinical association. CONCLUSIONS: For the first time we combined CEUS findings with motion adjustment software to quantitative determine perfusion parameters of a cohort of HHT patients. Hereby, we could identify a subset of HHT patients with two markedly increased parameter values in the shunt region compared to the hilus/hepatic parenchyma. This could contribute to sub-classify a high-risk group of HHT patients with therapeutic indication.
