Comparison of preoxygenation with a high-flow nasal cannula and a simple mask before intubation during induction of general anesthesia in patients undergoing head and neck surgery: Study protocol clinical trial (SPIRIT Compliant).

BACKGROUND: To assess the arterial oxygen partial pressure (PaO2) at defined time points during preoxygenation and to compare high-flow heated humidified nasal oxygenation with standard preoxygenation using oxygen insufflation via a facemask for at least 5 minutes, before intubation during induction of general anesthesia. METHODS: This randomized, single-blinded, prospective study will be conducted in patients undergoing head and neck surgery. After standard monitoring, the artery catheter at the radial artery or dorsalis pedis artery will be placed and arterial blood gas analysis (ABGA) for baseline values will be performed simultaneously. Each group will be subjected to 1 of 2 preoxygenation methods (high-flow nasal cannula or simple facemask) for 5 minutes, and ABGA will be performed twice. After confirming intubation, we will start mechanical ventilation and check the vital signs and perform the final ABGA. DISCUSSION: This trial aims to examine the trajectory of PaO2 levels during the whole preoxygenation procedure and after intubation. We hypothesize that preoxygenation with the high-flow nasal cannula will be superior to that with the face mask. STUDY REGISTRATION: This trial was registered with the Clinical Trial Registry (NCT03896906; ClinicalTrials.gov).

The most reliable time point for intact parathyroid hormone measurement to predict hypoparathyroidism after total thyroidectomy with central neck dissection to treat papillary thyroid carcinoma: a prospective cohort study.

PURPOSE: We assessed the optimal time for intact parathyroid hormone (iPTH) measurement for early detection of post-total thyroidectomy (TT) hypocalcemia in patients with papillary thyroid carcinoma (PTC). METHODS: In this single-center prospective cohort study, 143 patients who underwent TT with central neck dissection with or without lateral neck dissection for PTC were included. Biochemical profiles including iPTH, corrected total calcium, and ionized calcium within 24 h after surgery were analyzed. RESULTS: The 4-h postoperative iPTH was the most reliable predictor of post-TT transient or permanent hypoparathyroidism (cutoff for hypocalcemia was 3.75 pg/mL, AUC = 0.885, P < 0.001, sensitivity 81.6%, specificity 86.0%; cutoff for permanent hypocalcemia was 2.48 pg/mL, AUC = 0.819, P < 0.001, sensitivity 100%, specificity 57.8% calculated using ROC curves). CONCLUSIONS: The 4-h postoperative iPTH can most accurately predict hypoparathyroidism after TT with central neck dissection to treat PTC and facilitate the early discharge of low-risk postoperative hypoparathyroidism patients and decrease unnecessary overnight observation and calcium supplementation.

Hyperbaric oxygen therapy in a case of cervical abscess extending to anterior mediastinum, with isolation of Prevotella corporis.

We present a case of an odontogenic abscess, first spreading at the lateral cervical level and then in mediastinum. We isolated an anaerobic bacterium, Prevotella corporis, rarely documented in literature. The mortality rates of cervical abscesses secondary to odontogenic infections and complicated by mediastinitis vary from 10% to 40%. Treatment of descending mediastinitis involves multidisciplinary teams such as otorhinolaryngology, thoracic surgeons, infectious disease physicians, anesthetists and intensivists. Due to the combined treatment with surgical drainage within 48 hours of hospitalisation, antibiotics and subsequent hyperbaric oxygen therapy, we have achieved complete recovery of the patient.

Effect of wound massage on neck discomfort and voice changes after thyroidectomy.

BACKGROUND: Neck discomfort and voice change are common complications after thyroidectomy. These symptoms might be due to damaged laryngeal nerves, intrinsic structures, or extralaryngeal muscles. They can also occur without injury to any structure as with wound adhesion after thyroidectomy. The objective of this study was to determine causes of neck discomfort and voice change after thyroidectomy and to evaluate the effect of wound massage on symptom relief. METHODS: Forty-five female patients who underwent total thyroidectomy were included (21 in the experimental group and 24 in the control group). Wound massage was used as an intervention to release surgical adhesion. After wound massage education, participants in the experimental group received wound massage from 4 to 12 weeks after thyroidectomy. Analysis was performed for both groups. RESULTS: No laryngeal pathology was found after thyroidectomy. The experimental group had significantly better recovery from surgical adhesion and subjective visual analog scale, voice impairment score, and swallowing impairment score (all P < .01) compared with the control group. Voice analysis results associated with laryngeal movement (speaking fundamental frequency, voice range profile maximum, voice range profile range) also indicated significant recovery (P < .01) in the experimental group. These results indicate that local adhesion after thyroidectomy might affect general movement of the larynx and that wound massage could help patients recover normal general movement of the larynx. CONCLUSION: Neck discomfort and voice change after thyroidectomy are related to local wound adhesion, possibly associated with impairment of laryngeal vertical movement. Release of wound adhesion could help patients recover from neck discomfort and voice changes after thyroidectomy.

Liposuction of the Neck: Low Incidence of Nerve Injury and Other Complications in 987 Patients.

The neck is one of the most common areas treated by liposuction. Neck liposuction decreases fat volume, causes skin contraction, and restores a more youthful appearance. We present a large case series (n=987) performed by three dermatologic surgeons. Five patients developed temporary post-operative marginal mandibular dysfunction, one patient had submandibular gland ptosis and one patient had arterial bleeding. Seroma, skin necrosis, scarring, and hyperpigmentation did not occur following neck liposuction. Neck liposuction performed with tumescent local anesthesia is a safe procedure associated with a low incidence of nerve injury and other complications.

Neck Surgery Under Local Anesthesia.

The value of local anesthesia (LA) is widely recognized in oral and maxillofacial surgery. Many procedures can be performed with the use of local anesthetic alone, instilled at or near the site of surgery.The author presents a patient with neck tumor, where the tumor removal was managed under LA at outpatient clinic. Treatment and postoperative period was routine.Neck surgery under LA in outpatient environment shows a great potential in adequately selected patients.

Cervical Necrotizing Fasciitis of Odontogenic Origin and Hyperbaric Oxygen Therapy.

Necrotizing fasciitis (NF) is an infection of the soft tissues pathology with high mortality that spreads through the fascial planes and rarely seen in head and neck region. The cause of infection is often odontogenic problems. Broad-spectrum antibiotics, surgical debridement, and hyperbaric oxygen therapy (HBO) are important for the treatment of disease. We report a case of cervical NF in a 33-year-old woman who was treated with rapid surgical debridement and simultaneous HBO.

Comparison of intubation and tracheotomy in patients with deep neck infection.

Possible airway compromise further complicates treatment of deep neck infections (DNI). Airway management is crucial, but factors affecting the method of choice are unclear. We retrospectively evaluated adult DNIs in a single tertiary center covering 10 years, with special attention on airway management. Patient data were retrieved from electronic data files from 2007 to 2016, and included adult patients with DNI operated through the neck. Of the 202 patients, 127 (63%) were male, with a median age of 47 years. Odontogenic (n = 74; 35%) infection was the most common etiology. Intubation was the most common method of airway management (n = 165; 82%), and most patients (n = 102; 50%) were extubated immediately after surgery. Tracheotomy was performed primarily for 35 (17%) patients, and secondarily for 25 (15%). Two patients were managed in local anesthesia. Altogether 80 (40%) patients required care in the intensive care unit for a median of 7 days. Median hospital stay was 6 days for intubated patients and 10 days for primarily tracheotomized (p = 0.036). DNI extended to the mediastinal space in 25 (12%) patients, most of whom with odontogenic infection (48%), and necrotizing fasciitis (32%). Odontogenic infection was the most common etiology for DNI with increased risk for mediastinal involvement. Intubation was most common type of airway management with high success in immediate extubation after surgery. The need for tracheotomy seemed to lead to a longer hospital care and was associated with a more severe clinical course.

Does Postural Awareness Contribute to Exercise-Induced Improvements in Neck Pain Intensity? A Secondary Analysis of a Randomized Controlled Trial Evaluating Tai Chi and Neck Exercises.

STUDY DESIGN: Secondary analysis of a randomized controlled trial. OBJECTIVE: This secondary analysis aims to examine associations of improvement of chronic neck pain with patients' and intervention-related characteristics. SUMMARY OF BACKGROUND DATA: Previous research has found that Tai Chi and neck exercises significantly improved chronic nonspecific neck pain; however, the factors for treatment success remain unclear. METHODS: Subjects with chronic nonspecific neck pain were randomly assigned to 12 weeks of group Tai Chi or conventional neck exercises, and they attended 12 weekly sessions of 60 to 90 minutes. The interventions included exercises to improve body awareness, that is, interoceptive and postural awareness. A linear forward stepwise regression analysis was conducted to examine associations with improvements in neck pain intensity. Potential predictor variables included baseline pain, age, sex, the type of intervention, attendance rate and home practice duration, and changes in psychological well-being, perceived stress, and postural and interoceptive awareness during the study. RESULTS: Overall 75 patients were randomized into Tai Chi or conventional exercises, with the majority being women (78.7%). Participants reported an average pain intensity of 50.7 ±â€Š20.4 mm visual analog scale at baseline, and the average reduction of pain intensity in both groups was 21.4 ±â€Š21.3 mm visual analog scale. Regression analysis revealed that reductions in pain intensity from baseline to 12 weeks were predicted by higher pain intensity at baseline (r = 0.226, P < 0.001), a decrease in anxiety (r = 0.102, P = 0.001), and an increase in postural awareness (r = 0.078, P = 0.0033), explaining a total of 40.6% of variance. CONCLUSION: Neck pain improvement was significantly associated with changes in postural awareness in subject with chronic nonspecific neck pain independent of treatment characteristics. Training of postural awareness might be an important mechanism of action of different exercise-based interventions for chronic neck pain. LEVEL OF EVIDENCE: N /A.

The Impact of Pathologically Positive Lymph Nodes in the Clinically Negative Neck: An Analysis of 39,301 Patients with Papillary Thyroid Cancer.

PURPOSE: Management of patients with low-risk papillary thyroid cancer (PTC) with clinically uninvolved lymph nodes (cN0 LNs), but who harbor metastatic central LNs (pN1a), remains unclear. The number of central LNs examined, radioactive iodine (RAI) utilization, and survival were compared across cN0 patients based on pN stage: pN0 (negative) versus pNx (unknown) versus pN1a (pathologically positive). METHODS: Adults with a PTC ≥1 cm who were cN0 preoperatively were compared based on surgical pathology using the National Cancer Data Base (NCDB; 2003-2011), after univariate and multivariate adjustment. Overall survival (OS) was examined using Kaplan-Meier curves, the log-rank test, and Cox proportional hazards modeling. RESULTS: Overall, 39,301 patients were included; median tumor size was 1.9 cm. More LNs were examined for pN1a versus pN0 diagnosis (pN1a median = 5 LNs vs. pN0 median = 2 LNs; p < 0.0001), with a median of two central LNs found to be positive on surgical resection. Compared with pN0, pN1a patients were 78% more likely to receive RAI (odds ratio 1.78, 95% confidence interval [CI] 1.65-1.91; p < 0.0001). After adjusting for receipt of RAI, no difference in OS was observed for pN1a versus pN0 or pNx patients (p = 0.72). Treatment with RAI was associated with improved OS (hazard ratio 0.78, 95% CI 0.62-0.98, p = 0.03), but the effect of RAI did not differ based on pN stage (interaction p = 0.67). CONCLUSION: More LNs were examined for positive versus negative pN diagnosis in patients with cN0 PTC. Unsuspected central neck nodal metastases in cN0 PTC patients are associated with increased RAI utilization, but no survival difference.

Differentiation of malignant cervical lymphadenopathy by dual-energy CT: a preliminary analysis.

The accurate diagnosis of malignant cervical lymphadenopathy remains challenging. In this study, we determined the value of quantitative parameters derived from dual-energy computed tomography (DECT) for differentiating malignant cervical lymphadenopathy caused by thyroid carcinoma (TC), salivary gland carcinoma (SC), squamous cell carcinoma (SCC) and lymphoma. We retrospectively analysed 92 patients with pathologically confirmed cervical lymphadenopathy due to TC, SC, SCC and lymphoma. All patients received a DECT scan before therapy. Using GSI (gemstone spectral imaging) Volume Viewer software, we analysed the enhanced monochromatic data, and the quantitative parameters we acquired included the iodine concentration (IC), water concentration (WC) and the slope of the spectral HU curve (λHU). One-way ANOVA showed significant differences in the IC and λHU among different groups (P < 0.05). Post-hoc pairwise comparisons demonstrated the IC and λHU of TC group were significantly higher than those of SC, SCC and lymphoma groups (P < 0.05). In addition, the IC and λHU of SC group were significantly higher than those of the SCC and lymphoma groups (P < 0.05). Other comparisons of IC and λHU values showed no significant differences (P > 0.05). The quantitative parameters derived from DECT were useful supplements to conventional computed tomography images and were helpful for distinguishing different malignant cervical lymphadenopathies.

Blood-Sparing Techniques in Head and Neck Surgery.

Given the risks and potential complications of allogenic blood transfusion (ABT), as well as the expanding population of patients for whom ABT may not be an option, it is important for the treating physician, anesthesiologist, and surgeon to be well-versed in various alternatives. A good grasp of the concepts discussed in this article will help to customize a treatment plan that is specific to each patient's underlying disease and personal preferences without compromising appropriate medical care.

Myositis ossificans of the serratus anterior as a rare complication of massage: a case report.

INTRODUCTION: Myositis ossificans usually occurs in the vicinity of the elbow, knee joints, or hip joints, following obvious trauma or surgery. This is the first report on myositis ossificans of the serratus anterior. CASE PRESENTATION: In this report we present a case of myositis ossificans within the serratus anterior which developed as a complication due to long-term nape massage. The patient was a 29-year-old Han woman. Because heterotopic ossificans constricted her brachial plexus the surface of her right upper arm was slightly numb; the symptom disappeared after surgery. CONCLUSION: This case highlights that myositis ossificans can occur in the serratus anterior following long-term nape massage.

Method of nutrition of patients after major oral and craniofacial surgery and its effects on BMI changes during a half-year period of observation.

UNLABELLED: Injuries, deformations and tumours of the facial part of skull, oral cavity or neck often hamper or prevent normal food consumption. After surgery of these structures food intake may be decreased due to postoperative wounds, pain, swelling and trismus. The aim of the study was to evaluate nutritional state of patients treated surgically in the craniomaxillo- facial surgery department and determination of factors affecting body weight changes after surgery. MATERIAL AND METHODS: The study included 83 patients operated between 2008 and 2010 in the department of cranio-maxillo-facial surgery, due to: maxillo-facial defects (30 individuals), malignant tumours (23 individuals), injuries (19 individuals), benign tumours (11 individuals). The study was prospective. A method of nutrition during the observation period and BMI (Body Mass Index) value on the first day of hospitalization and after 10, 60, 180 days after hospital admission were considered. For statistical analysis of results a general regression analysis was used. RESULTS: Significant reduction of BMI was observed in all patients after 10 and 60 days from the start of hospitalization. A significant increase of this parameter was observed between Day 60 and Day 180 of observation, however the BMI values after 180 days were still significantly lower than the baseline. A dependency between these changes and a cause of hospitalization as well as nutrition during and after the stay at hospital has been shown. CONCLUSIONS: There is a distinct relationship between the worsening of nutritional state after craniofacial surgery and nutrition during and after hospitalization, and therefore special attention should be paid to the issue of nutrition during this period.

Wide-undermining neck liposuction: tips and tricks for good results.

BACKGROUND: Neck rejuvenation is one of the most sought after procedures in the restoration of the facial contour. Numerous techniques to improve the aesthetic outcome and reduce downtime have been described. In our experience, wide undermining and local anesthesia are key to obtaining good results in selected patients who want a quick recovery. This article presents our experience with liposuction of the neck and proposes some tips and tricks to master wide-undermining neck liposuction. METHODS: From January 2005 to September 2012, a total of 118 patients (34 males, 84 females) underwent neck liposuction. Patient selection was based mainly on age and neck-aging features. The procedure was performed with the patients under local anesthesia. A wide rhomboid-shaped skin undermining of the submandibular and neck area was performed and a very thin fat layer was preserved. Dressing was applied for 3 days. RESULTS: Improvement of the neck's contour was observed in all patients. Redefinition of the cervicomandibular angle and skin redraping of the cervical area occurred in all cases. No further touch-ups were needed. Edema and ecchymosis resolved in a few days. No major complications were observed. CONCLUSIONS: Our results show that wide-undermining neck liposuction performed under local anesthesia is an effective and safe procedure. Patient selection based on age and anatomical features was fundamental to obtain impressive improvement of neck contour.

Thyroid ablation with 1.1 GBq (30 mCi) iodine-131 in patients with papillary thyroid carcinoma at intermediate risk for recurrence.

BACKGROUND: Little is known about the medium- and long-term outcomes of thyroid ablation with 1.1 GBq (30 mCi) ¹³¹I in patients with papillary thyroid carcinoma who have a tumor >4 cm or accompanied by extrathyroid invasion or clinically detected lymph node metastases (cN1). The objective of this study was to evaluate the efficacy of ablation with 30 mCi ¹³¹I in this subgroup of patients and to report the medium-term outcomes. METHODS: We studied 152 patients with papillary thyroid carcinoma submitted to total thyroidectomy with apparently complete tumor resection, who had a tumor >4 cm or 2-4 cm accompanied by extrathyroid invasion or lymph node metastases, or ≤2 cm accompanied by both extrathyroid invasion and lymph node metastases. Patients with extensive extrathyroid invasion by the primary tumor were excluded. Lymph node involvement was detected by ultrasonography or palpation (cN1). RESULTS: Forty-two patients were prepared by administration of recombinant human thyrotropin and 110 by levothyroxine withdrawal. Posttherapy whole-body scanning revealed unequivocal ectopic uptake in three patients. When evaluated 9-12 months after ablation, 123 patients had achieved complete ablation (stimulated thyroglobulin [Tg] <1 ng/mL, negative anti-Tg antibodies, and neck ultrasonography); a new posttherapy whole-body scanning revealed persistent disease in 2 patients whose initial posttherapy whole-body scanning (obtained at the time of ablation) had already shown ectopic uptake; 12 patients presented with a Tg >1 ng/mL and 14 had positive anti-Tg antibodies without apparent metastases; 1 patient had metastases not detected at the time of ablation. Recurrence was observed in an additional 6 patients during follow-up (median 76 months). There was no case of death related to the disease. Therefore, an activity of 30 mCi failed in only 9 (6%) patients with persistent disease or recurrence after ablation. None of the variables analyzed (sex, age, tumor size, multicentricity, extrathyroid invasion, lymph node metastases, preparation [recombinant human thyrotropin or levothyroxine withdrawal]) was a predictor of ablation failure. CONCLUSIONS: An activity of 30 mCi ¹³¹I is effective in thyroid ablation in patients with stage T3 and/or N1 papillary thyroid carcinoma.

Effects of low-dose and high-dose postoperative radioiodine therapy on the clinical outcome in patients with small differentiated thyroid cancer having microscopic extrathyroidal extension.

BACKGROUND: It is unclear whether differentiated thyroid cancer (DTC) patients classified as intermediate risk based on the presence of microscopic extrathyroidal extension (ETE) should be treated with low or high doses of radioiodine (RAI) after surgery. We evaluated success rates and long-term clinical outcomes of patients with DTC of small tumor size, microscopic ETE, and no cervical lymph node (LN) metastasis treated either with a low (1.1 GBq) or high RAI dose (5.5 GBq). METHODS: This is a retrospective analysis of a historical cohort from 2000 to 2010 in a tertiary referral hospital. A total of 176 patients with small (≤2 cm) DTC, microscopic ETE, and no cervical LN metastasis were included. Ninety-six patients were treated with 1.1 GBq (LO group) and 80 patients with 5.5 GBq (HI group). Successful RAI therapy was defined as (i) negative stimulated thyroglobulin (Tg) in the absence of Tg antibodies, and (ii) absence of remnant thyroid tissue and of abnormal cervical LNs on ultrasonography. Clinical recurrence was defined as the reappearance of disease after ablation, which was confirmed by cytologically or pathologically proven malignant tissue or of distant metastatic lesions. RESULTS: There was no significant difference in the rate of successful RAI therapy between the LO and HI groups (p=0.75). In a subgroup analysis based on tumor size, success rates were not different between the LO group (34/35, 97%) and the HI group (50/56, 89%) in patients with a tumor size of 1-2 cm (p=0.24). In patients with smaller tumor size (≤1 cm), there was no significant difference in success rates between the LO (59/61, 97%) and HI groups (22/24, 92%; p=0.30). No patient had clinical recurrences in either group during the median 7.2 years of follow-up. CONCLUSIONS: Low-dose RAI therapy is sufficient to treat DTC patients classified as intermediate risk just by the presence of microscopic ETE.

[Head and neck cellulitis caused by a broken anesthesia needle]. / Cellulite cervicofaciale sur bris d'aiguille d'anesthésie.

INTRODUCTION: Third molar extraction is one of the most common surgical procedures in oral and maxillofacial surgery. Infectious complications can be estimated at 3.6% after local anesthesia. OBSERVATION: A 39-year-old female patient, presenting with important swelling of the face and neck after extraction of teeth 28 and 38 after local anesthesia. Clinical and radiographic data led to the diagnosis of facial cellulitis due to a foreign body on the sub angulo-mandibular region. Drainage under general anesthesia was performed and a fragment of anesthesia needle was removed. One month after surgery, the patient was considered cured. DISCUSSION: Breaking an anesthesia needle is a rare accident, which can occur during oral surgery under local anesthesia. Respecting the rules of good practice is essential in preventing this type of complication, especially since forensic rules for dental and oral surgery are becoming stricter.

[Faults and failure of tonsil surgery and other standard procedures in otorhinolaryngology]. / Fehler und Gefahren: tonsillektomie und andere Standard-Eingriffe.

Septoplasty, tonsillectomy (with and without adenoidectomy) and cervical lymph node excision are amongst the most common 50 inpatient operations in Germany. Intracapsular tonsillectomies (i.e., tonsillotomies) are increasingly performed. The aim of this study was to evaluate alleged medical malpractice, technical traps and pitfalls associated with tonsillectomy (TE), adenoidectomy (AE), tonsillotomy (TT), septoplasty (SP) and cervical lymph node excision (LN).A questionnaire was sent to the Regional Medical Conciliation Boards, Medical Services of the Health Insurance Companies (MDK) and Regional Institutes of Forensic Medicine in Germany to collect anonymized cases of complications or medico legal implications following TE, TT, AE, LN and SP. The results were discussed in the light of the contemporary medical literature and published verdicts in Germany.The response rate of our survey was 55.9%. The Institutes of Forensic Medicine contributed 9 cases, 49 cases were submitted by the Regional Conciliation Boards and none by MDK. All forensic cases were associated with exsanguinations following tonsillectomy including 2 children (5 and 8 years of age) and 7 adults (aged 20-69 years). The fatal post-tonsillectomy hemorrhage (PTH) had occurred 8.7 days on average; 4 patients experienced the bleeding episode at home (day 5, 8, 9 and 17, respectively). Repeated episodes of bleeding requiring surgical intervention had occurred in 6 patients. 3 Conciliation Boards submitted expert opinions concerning cases TT (1), AE (4), LN (3), SP (16) and TE (25). Cases with lethal outcome were not registered. Only 3 of the 49 cases were assessed as surgical malpractice (6.1%) including lesion of the spinal accessory nerve, wrong indication for TE and dental lesion after insertion of the mouth gag. The review of the medico legal literature yielded 71 published verdicts after AE and TE (29), LN (28) and SP (14) of which 37 resulted in compensation of malpractice after LN (16; 57%), TE (11; 41%), SP (8; 57%) and AE (2; 100%). There were 16 cases of PTH amongst 27 trials after TE resulting either in death (5) or apallic syndrome (5). Bleeding complications had occurred on the day of surgery in only 2 patients. 16 trials were based on malpractice claims following SP encompassing lack of informed consent (6), anosmia (4), septal perforation (2), frontobasal injury (2) and dry nose (2). Trials based on LN were associated exclusively with a lesion of the spinal accessory nerve (28), including lack of informed consent in 19 cases. 49 cases (69%) were decided for the defendant, 22 (31%) were decided for the plaintiff with monetary compensation in 7 of 29 AE/TE-trials, 9 of 28 LN-trials and 6 of 14 SP-trials. Lack of informed consent was not registered for AE/TE but LN (11) and SP (2).Complicated cases following TE, TT, ATE, SP and LN are not systematically collected in Germany. It can be assumed, that not every complicated case is published in the medical literature or law journals and therefore not obtainable for scientific research. Alleged medical malpracice is proven for less than 6% before trial stage. Approximately half of all cases result in a plaintiff verdict or settlement at court. Proper documentation of a thorough counselling, examination, indication, informed consent and follow-up assists the surgeon in litigation. An adequate complication management of PTH is essential, including instructions for the patients/parents, instructions for the medical staff, readily available surgical instruments and appropriate airway management in an interdisciplinary approach. Electrosurgical tonsillectomy techniques were repeatedly labeled as a risk factor for bleeding complications following TE. Institutions should analyse the individual PTH rate on a yearly basis. Contradictory expert opinions and verdicts of the courts concerning spinal accesory nerve lesions following LN are due to a lack of a surgical standard.
