Objective: Branchial apparatus anomalies of the fourth cleft are the rarest subtype of anomaly and occasionally present with suppurative thyroiditis or thyroid abscess due to their relationship with the thyroid gland. Surgical approaches vary and some surgeons favor cauterization of associated pyriform sinus tracts alone versus complete surgical excision. Currently, the literature is scarce and there is limited data on surgical outcomes and procedural steps. Here we describe a combination surgical technique for fourth branchial anomalies including: (1) surgical excision of the cyst and any external pit, (2) hemithyroidectomy, and (3) direct laryngoscopy with cauterization of pyriform apex tract, if present. Methods: A retrospective review was performed on all patients who underwent surgical excision of fourth branchial apparatus lesions (including fistulae, cysts, and sinus tracts) at an urban pediatric university hospital from 2000 to 2019. Data regarding demographics, medical history, surgical methods, complications, and surgical cure rates were collected. Results: A total of 16 patients (9 female, 7 male) underwent a combination surgical procedure for fourth branchial apparatus lesions. Success rate after primary surgery was 94%. One patient had residual disease requiring re-operation. Two patients had post-operative complications: 1 transient vocal fold paresis and 1 seroma, both managed conservatively. A consensus surgical algorithm was created based on operative steps present in the majority of cases. Conclusion: A combination approach to fourth branchial apparatus lesions—including endoscopic cauterization, external excision, and hemithyroidectomy—is safe and provides a high rate of primary cure. Although less invasive options exist, remnants of the branchial lesion, especially in the thyroid, may remain and cause recurrent issues. Therefore, we advocate for complete surgical excision of this rare developmental anomaly, especially when obvious thyroid involvement exists.

Traditionally, data regarding thyroidectomy were extracted from billing databases, but information may be missed. In this study, a multi-institutional pediatric thyroidectomy database was used to evaluate recurrent laryngeal nerve (RLN) injury and hypoparathyroidism.Retrospective multi-institutional cohort study.Tertiary care pediatric hospital systems throughout North America.Data were individually collected for thyroidectomies, then entered into a centralized database and analyzed using univariate and multivariable regression models.In total, 1025 thyroidectomies from 10 institutions were included. Average age was 13.9 years, and 77.8% were female. Average hospital stay was 1.9 nights and 13.5% of patients spent at least 1 night in the pediatric intensive care unit. The most frequent pathology was papillary thyroid carcinoma (42%), followed by Graves' disease (20.1%) and follicular adenoma (18.2%). Overall, 1.1% of patients experienced RLN injury (0.8% permanent), and 7.2% experienced hypoparathyroidism (3.3% permanent). Lower institutional volume (odds ratio [OR], 3.57; 95% CI, 1.72-7.14) and concurrent hypoparathyroidism (OR, 3.51; 95% CI, 1.64-7.53) correlated with RLN injury on multivariable analysis. Graves' disease (OR, 2.27; 95% CI, 1.35-3.80), Hashimoto's thyroiditis (OR, 4.67; 95% CI, 2.39-9.09), central neck dissection (OR, 3.60; 95% CI, 2.36-5.49), and total vs partial thyroidectomy (OR, 7.14; 95% CI, 4.55-11.11) correlated with hypoparathyroidism.These data present thyroidectomy information and complications pertinent to surgeons, along with preoperative risk factor assessment. Multivariable analysis showed institutional volume and hypoparathyroidism associated with RLN injury, while hypoparathyroidism associated with surgical indication, central neck dissection, and extent of surgery. Low complication rates support the safety of thyroidectomy in pediatric tertiary care centers.

Background Previous literature has reported on the incidence of short-term complications following resection of cervical lymphatic malformations (LMs) in children, however no research has yet investigated the long-term symptomatic course in these patients. This study aims to provide families and providers with an understanding of expectations for long-term symptom control, specifically in association with subsequent upper respiratory infections (URIs). Methods A retrospective chart review produced a case series of patients who underwent resection of cervical LM at a pediatric tertiary care center between 2007 and 2016. Demographic data, disease characteristics, operative details, and postoperative care were evaluated. Telephone surveys were conducted to ascertain the course of postoperative symptoms at the surgical site. Results Forty-three patients responded to the telephone survey. Thirty-seven (86.0%) had at least one postoperative surgical site symptom during subsequent URIs, with 28 (65.1%) reporting redness, 34 (79.1%) reporting swelling, and 18 (41.9%) reporting pain. Patients who experienced any of these symptoms universally indicated that they developed soon after the surgical resection, and over half reported that they improved over time. Postoperative seroma was associated with swelling during subsequent URIs (p = 0.04). Patients age 7 or were greater were more likely than those under 7 to report pain with URIs (p = 0.006). All 8 patients with drain placement for at least 2 days reported swelling during subsequent URIs. The incidence of the queried symptoms did not vary significantly based on sex, stage, histology, surgical subsite, or presence of residual disease. Conclusion While preoperative symptoms associated with cervical LMs are also frequently encountered postoperatively, particularly in some patient subgroups, improvement over time should be expected.

Objective To describe a case of a complex neck mass with final pathology significant for two synchronous lesions, a type 1 branchial cleft cyst and an enteric duplication cyst, and to discuss its management given the unique presentation.

Objective First branchial cleft anomalies (FBCAs) are rare and often misdiagnosed, which can delay proper management and increase surgical risks. Complete excision often requires parotidectomy with facial nerve dissection. The literature reports that younger patients more often have lesions deep to the nerve with higher rates of nerve injury. We hypothesized that the rate of nerve injury and complications in children with FBCAs was not different in those ≤2 years of age compared to those >2 years of age. Methods Retrospective review of pediatric patients who underwent resection of histopathologically confirmed FBCAs between 2007 and 2017 at a tertiary care, pediatric hospital. Presenting symptoms, lesion classification, prior procedures, imaging techniques, extent of surgery performed, facial nerve position, and complications were reviewed and compared between patients ≤2 years of age and >2 years of age at time of surgery. Results 43 cases of FBCAs were included in the study: 12 in the younger group and 31 in the older group. There was no difference between groups regarding the presenting symptoms, gender breakdown, lesion classification, prior procedures performed, or extent of surgery. Lesions were more commonly deep to or running between branches of the facial nerve in the younger group (33.3% vs 9.7%, p = .0496). Rates of postoperative complications and facial nerve weakness were comparable between the younger and older groups (8.3% vs 25.8%, p = .206; 25.0% vs 16.1%, p = .503). In combining the age groups, FBCAs located deep to the facial nerve had increased risk of nerve weakness postoperatively (RR 7.2) and those with a history of prior incision and drainage or resection had increased risk of postoperative complications (RR 2.36). Imaging was obtained on all subjects with accuracy rates of 80–100%. Conclusion Presenting characteristics of FBCAs in patients ≤2 years of age and >2 years of age are comparable, but lesions in younger subjects had a greater likelihood of being deep to or coursing between branches of the facial nerve. However, the rates of facial nerve injury and postoperative complications are comparable in younger and older children, owing likely to accurate preoperative imaging and appropriate surgical planning.

Introduction Successful pediatric revision thyroid surgery depends primarily on effective localization of recurrent or persistent lesions. Secondary to fibrosis and scarring, blind regional dissection can fail to retrieve the tissues of concern. Conventionally, high resolution CT or ultrasound of the neck has been used to map lesions within the thyroid bed. The success rate of excising recurrent lesions using these mapping techniques is at best 80%. We present a small series of patients in which hook wire localization was used to help localize and excise recurrent and/or persistent neck disease during secondary operations. Methods The wire-localization technique was utilized for a prospective case series of four pediatric patients with history of previous thyroidectomy and recurrent or persistent malignant thyroid disease. Results All four patients had recurrence or persistence of their disease process in the central or lateral neck. Patients successfully underwent preoperative hook wire localization of their persistent or recurrent neck lesions with successful subsequent neck dissection. Each case involved a single wire localization for a unique mass, equally a total of 4 lesions accessed by the technique over the four cases. The ultrasound-guided wire-localization technique assisted in the localization and excision of non-palpable lesions. No complications were seen in our small series as a result of this technique. Conclusion Hook wire localization may be a useful tool to help the surgeon more efficiently localize and excise recurrent or persistent disease in a scarred/previously operated field.

Introduction Limited information exists regarding short-term morbidity in the resection of lymphatic malformations. In order to make informed collaborative medical decisions, clinicians and families would benefit from information on 30-day outcomes and the expected course associated with surgical excision of lymphatic malformations. Methods A retrospective chart review was conducted to develop a case series of patients who underwent resection of lymphatic malformation at a pediatric tertiary care center between June 1, 2007 and September 30, 2016. Demographic data, disease characteristics, operative details, post-operative care, and adverse events in the 30-day post-operative period were analyzed. Primary outcomes included facial nerve dysfunction, seroma formation, re-admission, and overall rate of any complications. Secondary outcomes included operative time, duration of stay, and duration of drain placement. Results Forty-nine excisions were performed in 46 patients (21 male, 25 female). Median age was 5 years. All but 7 cases were performed as the initial primary intervention. Median operative time was 96 min (range 22–224). Higher stage lesions (3-5) were associated with a longer operative time (p = .03). Median length of stay was 2 days (range 0–35). Higher stage lesions were associated with an increased length of stay (p = .0004). Median duration of drain placement was 2 days (range 0–14), and was longer in higher stage lesions (p = .0002). Higher stage lesions (p = .002) and cases ultimately found to have residual disease (p = .019) were associated with an increased overall rate of complications; there was no association between cyst type and rate of complications. Seroma formation (31%) and transient facial nerve weakness (26%) were the two most common complications observed. There was no association between stage or cyst type and likelihood of seroma formation. Seromas resolved after a median duration of 3 months and transient facial nerve weakness resolved after a median duration of 2 months. 3 patients required return to the OR and 1 patient was readmitted. Conclusion The overall rate of adverse events after surgical excision of cervical lymphatic malformations is relatively low. Increased rates of complications can be expected with higher stage. Similarly, for these higher stage lesions, a longer operative time, hospital stay, and duration of drain placement can be expected.

Importance Limited information exists about the short-term morbidity of parotidectomy in children. This information is important when counseling parents and planning treatment for children with parotid masses. Objective To examine 30-day perioperative outcomes after parotidectomy in the pediatric population. Design, Setting, and Participants A prospective case series of 87 pediatric patients who underwent parotidectomy from January 1, 2008, to June 30, 2015, performed by 2 pediatric head and neck specialists in a tertiary care pediatric hospital. Main Outcomes and Measures Thirty-day perioperative complications, postoperative facial nerve function, reoperation rates, and readmission rates were the main outcome measures. Secondary outcome measures were operative time and length of stay. Results Ninety parotidectomies (71 superficial and 19 total) were performed in 87 patients (48 male and 39 female). Mean age at operation was 8.3 years. Eighty-five of the cases (94%) were performed for benign disease. Mean operative time was 4.09 hours (range, 1.58-10.43 hours) and mean length of stay was 2.24 days (range, 0.97-4.33 days). Immediate postoperative facial weakness was observed in 32 cases (36%); 10 of these cases (31%) involved the upper branch and 29 (90%) involved the lower branch. Immediate postoperative paresis occurred more often after total parotidectomy vs superficial parotidectomy (11 of 19 [58%] vs 21 of 71 [30%];P = .03) but was unrelated to the etiologic cause of the patients’ parotid disease. Thirty of 32 cases (94%) of facial nerve weakness were transient, and the mean time to resolution was 61 days. Eleven complications (12%) other than facial nerve weakness occurred during the 30-day postoperative period. Three patients (3%) required a return to the operating room for hematoma or wound dehiscence. One patient (1%) required readmission in the 30-day postoperative period for contralateral parotitis. Conclusions and Relevance We observed a low rate of 30-day perioperative complications as a result of superficial or total parotidectomy for pediatric parotid disease. Major adverse events included return to the operating room and 1 wound infection. Only 1 patient required readmission. Transient weakness of the facial nerve is relatively common, observed more often in the lower division, and can be expected to resolve in most patients by an average of 2 months.

Objectives/Hypothesis: The anatomy of the anterior neck in the area of the hyoid, thyrohyoid membrane, and epiglottis is herein redescribed and compared to its classical depiction. The concept of the posterior hyoid space (PHS) is defined and substantiated through review of archived tissue and cadaver larynx dissection as well as by observation at many surgical dissections. The true anatomy of these relationships provides an insight into the effectiveness of the Sistrunk procedure. The author believes that recurrence of thyroglossal duct cysts (TGDC) occurs as a consequence of incomplete resection of: 1) microscopic suprahyoid ductules and/or 2) infra- and perihyoid tissue. Study Design: The senior author has been using the concept of the posterior hyoid space as applied to the Sistrunk procedure for more than 20 years. A retrospective study was done on cases from April 2003 to August 2008, and outcome was reviewed and compared to historical controls to determine the impact of applying this anatomic concept. Methods: A retrospective chart review was undertaken on 60 surgical cases performed for a 5-year period with clinical follow-up extended to an additional 7 months. Data collected included age at surgery, presenting symptoms, imaging characteristics, thyroid status, pathology results, and postoperative complications. All 60 were under the age of 18 who underwent a modified Sistrunk procedure and had a postoperative diagnosis of TGDC. Each patient had a minimum follow-up period of 4 months to check for recurrences. No revision was included in this study. Results: Sixty patients met criteria for the study. There was one recurrence (1.67%); a complication rate of 6.67%. Complications were minor and wound related. Mean follow-up was 17 months. Conclusions: The technique of applying the concept of a PHS to ensure the complete resection of the middle third of the hyoid bone and offending tissues is believed to decrease recurrence of TGDC secondary to incomplete resection in the perihyoid area.

Objectives: We undertook to identify data that facilitate determination of an accurate diagnosis of the cause of stridor in infants and to develop a framework to conceptualize the problem. Methods: We reviewed medical records of patients less than 1 year of age with the presenting symptom of stridor who were initially evaluated in the outpatient setting of a tertiary children's hospital. Infants with obvious congenital syndromes, cerebral palsy, or hypotonia were excluded. All infants underwent history-taking, physical examination, and when symptoms were mild, office flexible laryngoscopy. With moderate or severe stridor, a more complete endoscopic evaluation was undertaken in the operating room. Results: Of 202 patients, 119 (59%) were boys and 83 (41%) were girls. Their ages ranged from 3 days to 11 months; 175 (87%) were 6 months of age or younger. Congenital anomalies were diagnosed as the cause of stridor in 170 (84%). Congenital laryngeal anomalies caused stridor in 157 (78%); congenital tracheal abnormalities were the cause in 13 (6%). The most common congenital laryngeal anomaly was laryngomalacia (94%). Forty-two (21%) of the 202 patients had at least 1 other anomaly that contributed to airway compromise. Half of all patients had laryngopharyngeal reflux, the most common associated condition. Of patients referred with a presumptive diagnosis by non-otolaryngologists, 28 of 94 (30%) were referred with erroneous presumptive diagnoses for which they were being treated, the most common of which was tracheomalacia. Conclusions: A standard, rational approach to the evaluation of stridor in infants facilitates management. A framework for evaluation is presented.

Otolaryngologists are frequently consulted for the evaluation and treatment of pediatric epistaxis. There is a lack of consensus as to the optimal approach to this problem. This study evaluated an approach used to evaluate and treat patients referred on an outpatient basis.Retrospective study.Charts from 90 patients referred for the treatment of epistaxis were reviewed.Anemia was identified in 22% of patients. An abnormal coagulation study was identified in 7.8% of patients. Computed tomography (CT) imaging of the sinuses was obtained in nearly 90% of patients and revealed no suspicious masses. Opacification of the sinuses consistent with sinusitis was commonly seen. The majority of cases were resolved by the first follow-up visit with a topical nasal emollient.The outpatient evaluation of epistaxis should include a screen for anemia and coagulopathy. Routine CT imaging of the sinuses is unhelpful and is not recommended. The majority of cases are easily treated with rehydration of the nasal mucosa. Consideration should be given to rhinosinusitis as a co-existing factor in patients with epistaxis.

The embryology, presentation, imaging, and treatment of the thyroglossal duct cyst will be reviewed. Anatomic features and surgical technique to prevent complications and recurrence will be discussed. Included in the discussion will be the management of thyroglossal duct cyst malignancy and ectopic thyroid.

Defects of embryologic development give rise to a variety of congenital lesions arising from the epithelium and are among the most common congenital lesions of the head and neck in the pediatric population. This article presents several congenital lesions of epithelial origin, including congenital midline cervical cleft, pilomatrixoma, dermoid, foregut duplication cysts, and preauricular sinuses and pits. In addition, the management of these lesions is reviewed.

Malignant tumors are extremely uncommon in infants, specifically in the head and neck region. We present a three-day-old infant with a large, polypoid, soft tissue mass arising from the floor of the mouth. Histologically, this neoplasm consisted of hypercellular and myxoid areas. A mixture of poorly oriented, small, undifferentiated, hyperchromatic, and round to elongate spindle cells was seen. A high degree of striated muscle differentiation was present, along with areas marked by a herringbone pattern, as well as hemangiopericytic vessels and rare mitosis. Immunohistochemical examinations revealed strong nuclear staining for myogenin and diffuse cytoplasmic staining for desmin and muscle-specific actin (HHF-35). The tumor did not stain for S-100. Based on histologic results and immunostains, this lesion was diagnosed as spindle cell rhabdomyosarcoma. This type of lesion involving the tongue is rarely seen in females, neither in association with a herringbone pattern nor with hemangiopericytic vessels. Furthermore, rare benign and malignant spindle lesions, such as cellular fibromatosis, fetal rhabdomyoma, infantile hemangiopericytoma, infantile rhabdomyofibrosarcoma, and infantile fibrosarcoma, should be in the differential diagnosis and excluded.

Objective To evaluate the work-up and treatment of pediatric epistaxis in an outpatient clinical setting, with a focus on the diagnostic utility and associated costs of nasal endoscopy and adjunctive laboratory data. Study design Retrospective, case series. Methods Children under 18 years of age seen in an outpatient clinical setting at a tertiary care hospital between 2004 and 2012 for the primary diagnosis of epistaxis were identified. Patient characteristics were analyzed from a statistical and cost perspective. Results A total of 175 patients with epistaxis were included. One hundred twenty-two (69.7%) were male, with a mean overall age of 9.1 years (range 5 months to 17.9 years). The duration of bleeding ranged from 0.25 to 84 months (mean 11.5 months). Nasal endoscopy was performed in 123 (70.2%) patients. Three (2.4%) had nasal polyps, and 1 (0.8%) a juvenile nasopharyngeal angiofibroma. The average age of patients with nasal masses was significantly older (16.2 years versus 10.4 years, p = 0.008). Of 131 patients with available blood work, laboratory values demonstrated anemia in 27 (20.6%) patients, elevated partial thromboplastin time in 5 (3.8%), and an abnormal platelet function analysis in 1 (0.8%) patient. Those with anemia were statistically younger (p = 0.001), than those with either normal labs or abnormal coagulation studies. Epistaxis resolved in 88/135 (65.2%) who had follow-up visits. Conclusion The majority of pediatric epistaxis cases resolved with nasal mucosa hydration. Nasal endoscopy can be reserved for teenaged patients with epistaxis, and routine laboratory screening may be useful in select cases based on the clinical judgment.

Objective To assess the type and rate of complications in the postoperative period of pediatric patients undergoing the Sistrunk procedure. Study Design A retrospective review of patients with a diagnosis of thyroglossal duct cyst who had not had corrective surgery previously. An attempt to standardize the study was made as follows: all patients had surgery under the direction of one surgeon, using the Sistrunk procedure with minor modifications from its original description. Complications were divided into major and minor categories. Methods Charts were reviewed for age, se-, preoperative assessment, and postoperative follow-up. Complications were recorded. A postoperative telephone survey was conducted. Results A minor complication rate of 29% was observed. There were no recurrences or major complications. Conclusions The Sistrunk procedure remains the operation of choice for removal of the thyroglossal duct cyst. When the surgery is properly performed, with attention to key surgical landmarks, the risk of major complication is minimal. Complications that do occur are minor and wound related.

There is always concern for a malignancy or other serious disease when a child presents with a chief complaint of a neck mass. However, a neck mass in child is commonly inflammatory or congenital rather than neoplastic. A complete history and physical exam will often provide enough information to guide management and reassure the concerned parents. In some cases, laboratory tests, radiologic studies or a surgical procedure may be necessary to determine a specific diagnosis and treatment plan. An organized and systematic approach is recommended and detailed in this review.

Early posttransplant lymphoproliferative disorders (EPTLDs) represent the first changes in posttransplant lymphoproliferative disorders (PTLDs) morphologic spectrum. EPTLD data are available mostly from case reports and series that include other types of PTLD. Fifteen EPTLDs were reviewed retrospectively. Clinical data, histopathology, clonality, and Epstein- Barr virus (EBV) status were correlated with staining intensity to an antibody for phosphorylated S6 (pS6) ribosomal protein, a downstream effector of mammalian target of rapamycin (mTOR). Median time from transplantation to EPTLD was 50 months (range, 7-135 mo). EPTLDs involved tonsil and/or adenoids (n = 11) and lymph nodes (n = 4), all of which were nonclonal and EBV-encoded RNA-positive. Most (n = 11) were plasmacytic hyperplasia and florid follicular hyperplasia (n = 4). All regressed with reduced immunosuppression, and had increased pS6 staining compared with normal tonsil (P = .002, F test). EPTLDs developed later than previously reported, involved mostly tonsils/adenoids, were EBV-encoded RNA (EBER) positive, showed increased pS6, and had excellent clinical outcome with reduction of immunosuppression.

Objective To review the surgical anatomy and histopathology of second branchial cleft fistulae. Study design Retrospective study of patients treated for second branchial cleft fistulae at a tertiary care pediatric hospital. The senior author noted anatomic and histologic features of second branchial cleft fistulae, not previously described. Setting Tertiary care children's hospital. Patients and methods Retrospective examination of 28 patients was conducted who were operated upon for second branchial cleft fistula. Data collected included age at surgery, initial presentation, imaging characteristics prior to surgery, laterality of the fistula tract, pathology results and follow-up data. Results Twenty-eight patients met the criteria for inclusion. Three patients (11%) had bilateral fistulae. 11 (39%) were male and 17 (61%) were female. 23 (74.2%) tracts were lined with ciliated columnar epithelium, 3 (9.7%) had cuboidal epithelium, and 5 (16.7%) had squamous epithelium. Nineteen (61.3%) tracts contained salivary tissue. Of the unilateral fistula tracts, 25 (100%) were on the right side. Of the 3 patients with bilateral lesions, 2 (66%) had associated branchio-oto-renal syndrome (BORS). Conclusions Second branchial cleft fistulae are rare. They are usually right-sided. If bilateral fistulae are present, one should consider an underlying genetic disorder. The histology of the fistulae mostly demonstrates ciliated columnar epithelium with the majority of specimens showing salivary tissue. There is a clear association with the internal jugular vein (IJV). Dissection should continue until superior to the hyoid bone, ensuring near complete surgical dissection and less risk of recurrence.

Aggressive juvenile fibromatosis, though allegedly a benign process, is as frustrating to manage as it is perplexing to comprehend. The treatment is primarily surgical, with chemotherapy and radiation therapy recently finding support as adjuncts in selected circumstances. Though there is no agreement regarding the etiology of fibromatosis, many have suspected hormonal or traumatic influences. There has been historical, clinical and experimental data demonstrating that fibromatosis seems to be under the influence of estrogen. There have also been anecdotal reports that this tumor has regressed with the use of tamoxifen. To our knowledge, no one has tested these tissues for the presence of estrogen/progesterone receptors. Recently, over a short period of time, we at Children's Memorial Hospital, Chicago, have treated four youngsters with this disorder. All operative specimens were submitted for estrogen and progesterone assays. Although these cases were indistinguishable on histologic examination, two of the four exhibited the presence of estrogen/progesterone receptors. We propose, that from these observations, there potentially may be derived a histochemical classification based upon the presence or absence of estrogen/progesterone receptors. This would serve as an added reference in the definition and treatment of this disease. Should hormonal receptors be present, agents such as tamoxifen conceivably could be employed as part of a post-operative maintenance regimen similar to those protocols applied in the management of hormonally responsive breast cancer.

Tonsillectomy is associated with postoperative nausea and vomiting (PONV) if no prophylaxis is administered. Previous studies have shown that a single dose of dexamethasone decreases the incidence of PONV. The most effective dose of dexamethasone to affect clinical outcome is yet to be defined.One-hundred-twenty-five children were enrolled in a double-blind, prospective, randomized, dose-escalating study of dexamethasone: 0.0625, 0.125, 0.25, 0.5, or 1 mg/kg, maximum dose 24 mg. Nonparametric ANOVA was used to analyze the incidence of vomiting by treatment group for 0 toor =5 h,5 to 24 h. The Cox Proportional Likelihood Ratio Test was used to compare the time of first vomit and time to first pain medication across treatment groups.There was no difference in the incidence of vomiting for the five escalating doses of dexamethasone in the time period. There were no differences in secondary outcomes (analgesic requirements, time to first liquid, and change in voice) across treatment groups.We conclude that the lowest dose of dexamethasone (0.0625 mg/kg) was as effective as the highest dose of dexamethasone (1.0 mg/kg) for preventing PONV or reducing the incidence of other secondary outcomes following tonsillectomy or adenotonsillectomy. There is no justification for the use of high-dose dexamethasone for the prevention of PONV in this cohort of children.

Objective We sought to review the presentation, evaluation, and treatment of branchial anomalies in the pediatric population and to relate these findings to recurrences and complications. Study Design and Setting We conducted a retrospective study at a tertiary care pediatric hospital. Patients Ninety-seven pediatric patients who were treated for branchial anomalies over a 10-year period were reviewed. Patients were studied if they underwent surgical treatment for the branchial anomaly and had 1 year of postoperative follow-up; 67 children met criteria, and 74 anomalies were studied. Results Patients with cysts presented at a later age than did those with branchial anomaly fistulas or sinus branchial anomalies. 32% of branchial anomalies were previously infected. Of these, 71% had more than one preoperative infection. 18% of the BA were first arch derivatives, 69% were second arch derivatives and 7% were third arch derivatives. There were 22 branchial cysts, 31 branchial sinusies and 16 branchial fistulas. The preoperative and postoperative diagnoses differed in 17 cases. None of the excised specimens that contained a cystic lining recurred; all five recurrences had multiple preoperative infections. Conclusions Recurrence rates are increased when there are multiple preoperative infections and when there is no epithelial lining identified in the specimen.

Objective To determine the role of angiogenesis in the clinical behavior and pathogenesis of lymphangioma tumors. Design A retrospective study. Median follow-up period was 44.5 months. Setting Children's Memorial Hospital, Chicago, Ill. Patients Tumor specimens from 12 pediatric patients who underwent surgical excision of cervicofacial lymphangioma were examined for expression of angiogenic inducer vascular endothelial growth factor (VEGF) and angiogenic inhibitor pigment epithelium–derived factor (PEDF) using immunohistochemical analysis. Specimens were divided into recurrent and nonrecurrent tumors based on clinical information. Main Outcome Measures Staining patterns of VEGF and PEDF were evaluated in lymphangioma specimens. Staining patterns were then compared in both recurrent and nonrecurrent groups and graded in a blinded fashion. Histological evidence of increased angiogenesis including microvascular density, stromal fibrosis, and inflammation were graded in each group and correlated with recurrence. Results Lymphangioma specimens demonstrated histological evidence of increased angiogenic activity including multiple areas of increased VEGF staining combined with little PEDF staining. Sex, age at onset, or tumor location did not correlate with recurrence. Furthermore, recurrent specimens had increased histological evidence of angiogenesis as well as increased VEGF and decreased PEDF activity compared with nonrecurrent lesions. Conclusions Lymphangiomas exhibit tumorlike pathogenesis owing to the high expression of angiogenic inducers compared with the low expression of inhibitors. Recurrence may be influenced by this imbalance of angiogenic mediators. Further research with antiangiogenic therapy using agents such as PEDF analogues or anti-VEGF receptor antibodies is indicated because they may stabilize or suppress the growth of these neoplasms.

Background Noninflammatory masses of the salivary gland region in children are extremely rare. Therefore, very few published individual and institution-based experiences exist. Design Retrospective chart review from 1990 through 1997. Setting University-based children's hospital. Design Patients 18 years of age or younger with a tumor in the salivary gland region. Masses of infectious origin were excluded. Hemangiomas and lymphangiomas were tallied for relative incidences only. Results Three hundred twenty-four consecutive cases of salivary gland masses were found: 192 hemangiomas (59.2%), 89 lymphangiomas (27.5%), and 43 (13.3%) solid masses. No significant difference was found between the age at presentation of the patients with benign solid tumors and the patients with malignant solid tumors (mean + SEM age, 7.2 + 0.7 years). Sixty-one percent of the masses were found in the parotid region; 18% were localized to the submandibular gland region; and the remaining 21% were located in a minor salivary gland site. The most common benign perisalivary masses were pilomatrixomas (20.9%), followed by pleomorphic adenomas (11.6%). The most common malignant masses were mucoepidermoid carcinomas (9.3%), followed by rhabdomyosarcomas (7.0%). Treatment was individualized to the disease. Twenty-two patients had adequate data for follow-up analysis (mean + SEM follow-up, 30.0 + 8.4 months). Four patients (18.2%) experienced recurrent or residual disease and were alive with disease at last follow-up, and 100% of our population demonstrated disease-specific survival at last follow-up. Conclusions Vascular lesions outnumber solid tumors of the salivary gland region. The most common salivary tumors were pleomorphic adenomas, followed by mucoepidermoid carcinomas. Although certain solid salivary masses may demonstrate locally aggressive behavior, the overall prognosis is favorable.

We describe a case of enteric duplication arising from the floor of the mouth and base of the tongue of a 7-year-old child. This mass was asymptomatic and was detected on routine dental examination. The unusual location, possible etiology, and a brief review of the literature are discussed.

We assessed the safety and efficacy of oral transmucosal fentanyl citrate (Fentanyl Oralet@; Abbott Laboratories, Abbott Park, IL), administered preoperatively to provide both preoperative sedation and postoperative analgesia, in a randomized, double-blind, placebocontrolled study in 40 children, 2-10 yr of age, scheduled for tonsillectomy. In the preoperative holdin H area, one group (Group 0) received Fentanyl Oralet (fentanyl lo-15 pg/kg), and the other (Group IV) received only the candy matrix. Patients in Group 0 received an IV injection of saline, and those in Group IV received an IV injection of fentanyl(2 pg/kg) after removal of the first tonsil. Except for the opioid, patients received a standard anesthetic. Preoperative sedation and cooperation were assessed. Postoperative pain was evaluated using an objective pain scale. Patients in Group 0 were more sedated but no more cooperative at the induction of anesthesia compared with those in Group IV. No patient vomited preoperatively or experienced preoperative or postoperative desaturation. Time to postanesthesia care unit (PACU) discharge was not different between groups. There was no significant difference in the number of patients requiring morphine in the PACU (6 of 21 in Group 0 versus 10 of 19 in Group IV). Plasma fentanyl concentrations were not a reliable indicator of the need for postoperative morphine. Among the patients who required morphine postoperatively, there was an ll-fold variation in plasma fentanyl concentrations at the time of morphine administration. Derived pharmacokinetic parameters were similar to those previously reported in children; bioavailability of the fentanyl in Fentanyl Oralet@ was 0.33. We conclude that premeditation with Fentanyl Oralet@ did not differ with IV fentanyl in regard to the induction of anesthesia and postoperative analgesia. Implications: In this double-blind, randomized study, we studied the efficacy of Fentanyl Oralet@ (lo-15 pg/ kg) preoperatively for providing postoperative analgesia in children undergoing tonsillectomy. We found no incidence of preoperative desaturation or vomiting in any patient. This is in contrast to other studies, in which there was a longer time interval between Fentanyl Oralet@ completion and induction of anesthesia. The bioavailability of the fentanyl in Fentanyl Oralet@ was estimated to be 33%, which is less than that reported in adults (approximately 50%). There was no difference in postoperative opioid requirements between patients who received 2 Fg/kg of fentanyl IV and those who received Fentanyl Oralet@. (Anesth Analg 1998;86:66-70)

Objective To assess the effectiveness of ultrasonography for determining which pediatric midline neck masses should be treated surgically. Design Retrospective study. Setting Tertiary care pediatric hospital. Patients Pediatric patients with a midline neck mass who underwent ultrasonography from 2003 to 2011. Main Outcome Measures Demographics, ultrasonography, and surgical and pathology reports were studied. The ultrasonography findings and pathological analyses were compared. Results One hundred twenty-two patients met the inclusion criteria. The most common diagnosis obtained by ultrasonography was thyroglossal duct cyst (48.4%), followed by reactive lymph node (27.9%). Ninety-five of 122 patients (77.9%) underwent surgery. Twenty-seven patients (22.1%) were treated nonsurgically. The diagnosis and characteristics obtained from ultrasonography were confirmed by surgical pathologic analysis in 84.2% of the surgical cases. Of the 95 patients who underwent surgery, 85 (89.5%) had a non–lymph node lesion diagnosed by ultrasonography and confirmed by pathologic analysis. Ultrasonography was only 66.1% accurate in specifically diagnosing thyroglossal duct cyst and 30.0% accurate in specifically diagnosing reactive lymph node when compared with surgical specimens. Conclusions Ultrasonography is helpful in determining the pediatric midline neck masses that need to be removed surgically. It is less helpful in determining the exact pathologic characteristics of the lesion.

Objective To provide a review of the current information on the etiology, clinical presentation, management, and outcome of pilomatrixoma of the head and neck in children. Design Retrospective review. Setting A tertiary care pediatric center. Patients Fifty-one pediatric patients with a diagnosis of pilomatrixoma of the head and neck. Intervention All patients underwent excision of pilomatrixoma from January 1997 to March 1999. A total of 55 tumors were studied. Results A preponderance of girls (n = 36; 71%) presented with this condition. The average age at diagnosis was 5.7 years, and the average size of the lesion was 1 cm. The skin of the cheek and the periorbital area were the most commonly involved sites. Only 27 lesions (49%) had a correct preoperative diagnosis. Two (4%) of 55 tumors recurred after complete surgical excision. Main Outcome Measures The age and sex of the patient, preoperative diagnosis, time elapsed before diagnosis, site and size of the tumor, length of follow-up, presence of multiple or previous pilomatrixomas, and recurrence. Conclusions Preoperative diagnosis may be improved with increased awareness of pilomatrixoma, a common, benign skin tumor in children. Clinical findings will aid in an accurate diagnosis. Recurrence after complete local excision is rare.

The experience with laryngotracheal reconstruction in 20 children in Chicago is reviewed. Nine of the 20 children (45%) operated upon had congenital subglottic stenosis. Ten (50%) had acquired stenosis. One child was classified as having combined types. All patients underwent laryngotracheal reconstruction with autogenous costal cartilage grafts. Eight patients had both anterior and posterior costal cartilage grafts with stent insertion. One had a posterior costal cartilage graft only. Sixteen of the 20 children (80%) have been decannulated. Midtracheal or lower tracheal disease concomitant with laryngotracheal stenosis is an indication that endoscopic management of severe subglottic stenosis is likely to fail. Early laryngotracheal reconstruction is indicated for patients with a high likelihood of failure of endoscopic management and for those with severe cricoid cartilage deformities. Our results support the use of laryngotracheal reconstruction as an alternative to conservative (endoscopic) management of severe subglottic stenosis in carefully selected patients.

A previously undescribed deficiency of the posterior cricoid at the midline, wherein the mucosa overlying this deficiency is intact, is described. Clinically this presents as a variety of subglottic stenoses wherein the narrowing is primarily in the transverse subglottic diameter; the symptoms are, therefore, those of airway obstruction not laryngeal incompetence. It is suggested that this deformity has been previously overlooked by laryngologists and pathologists by virtue of a postmortem routine in which the larynx is routinely split in the posterior midline. Demonstration in these cases was by serial horizontal section of the intact, unsplit, whole larynx.
