Women Surgeons Who Contributed to the Development of Pediatric Otolaryngology in the United States.

OBJECTIVE: Our goal was to identify the early pioneering women surgeons in the United States who devoted their career or the majority of their practice to the care of otolaryngologic disorders in children. We sought to share their stories, recognize their contributions to the surgical subspecialty now known as pediatric otolaryngology, and acknowledge their vision and leadership. DATA SOURCES: Primary sources include books, published articles in the medical literature, newspaper articles, memorials/obituaries in both the medical literature and lay press, web logs, the John Q Adams Center for the History of Otolaryngology to include the Women in Otolaryngology, a number of otolaryngology departments, and children's hospitals nationwide. Interviews were conducted with former colleagues and senior pediatric otolaryngologists. REVIEW METHODS: Following review of all available information, women surgeons were included in this study if there was documentation of a clinical practice involving the otolaryngologic care of children in the United States before 1985 with demonstration of the education of others in this discipline. RESULTS: Six women surgeons were identified: Drs. Alice G Bryant, Margaret F. Butler, Ellen James Patterson, Emily Lois Van Loon, LaVonne Bernadene Bergstrom, and Joyce A. Schild. CONCLUSION: Six pioneering women surgeons in the United States have been identified who devoted their practice to the care of otolaryngologic disorders in children and mentored or trained other health care providers. The stories of their lives, their contributions to the care of otolaryngologic disorders in children, and their work as mentors or educators have been described. Laryngoscope, 134:40-46, 2024.

Endoscopic pediatric endonasal retrieval of transorbital projectile: An illustrative multimedia report.

Air guns, particularly BB (ball-bearing or bullet ball) guns, have gained significant power and velocity over the last few decades. More than 145,000 pediatric patients suffered injuries attributed to air guns in the United States between 2001 and 2011, and approximately 22,000 pediatric emergency department visits are attributed to air gun-related injuries annually (Hyak et al., 2020 [1]). This study aims to describe an effective surgical technique in addressing maxillofacial injuries caused by BB gun projectiles in the pediatric population. We present a detailed surgical approach for endoscopic endonasal retrieval of a transorbital projectile in a 13-year-old male who sustained a maxillofacial BB gun injury, with the goal of restoring sinonasal function in a minimally invasive fashion.

Adolescent subdural empyema in setting of COVID-19 infection: illustrative case.

BACKGROUND: Coronavirus disease 2019 (COVID-19) is an ongoing viral pandemic that has affected modern medical practice and can complicate known pathology. The novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) causes symptoms that may mimic a viral pneumonia, with potential for serious sequelae, including acute respiratory distress syndrome, coagulopathy, multiorgan dysfunction, systemic vascular abnormalities, and secondary infection. OBSERVATIONS: The authors describe a case of a 15-year-old boy who presented with a right subdural empyema and sinusitis while having active COVID-19 infection. The patient initially presented with left-sided weakness, frontal sinusitis, and subdural empyema. Emergent surgery was performed for evacuation of empyema and sinus debridement. Samples of purulent material within the subdural space were tested for SARS-CoV-2 by reverse transcriptase polymerase chain reaction. The patient had a successful recovery and regained the use of his right side after combined treatment. To our knowledge, this is the first reported case of a bacterial subdural empyema associated with frontal sinusitis in a coinfected patient with COVID-19 without evidence of COVID-19 intracranial infection. LESSONS: A subdural empyema, which is a surgical emergency, was likely a superinfection caused by COVID-19. This, along with the coagulopathy caused by the virus, introduced unique challenges to the treatment of a known pathology.

The Relevance of and Surgical Approach to the Suprahyoid Region in Thyroglossal Duct Surgery.

OBJECTIVES: Persistent or recurrent disease following excision of a thyroglossal duct cyst/sinus (TGDC) is often found in the suprahyoid region. Cadaver dissections were performed to identify and name important surgical landmarks in the suprahyoid area; a histopathologic analysis of surgical specimens was completed to determine the incidence and extent of microscopic disease; and clinical outcomes were compared to determine the efficacy of a specific anatomic dissection. STUDY DESIGN: Retrospective case series. METHODS: Standardized dissections of four adult cadavers were performed. Consecutive surgical specimens were examined for evidence of microscopic TDGC disease in the suprahyoid region, measuring the greatest width and length of disease. A retrospective review of all consecutive TGDC procedures was completed. RESULTS: The important surgical landmarks in the suprahyoid area were identified in all cadavers. Microscopic disease in the suprahyoid area was found in 79% (37 of 47) of surgical specimens. The mean greatest length and width of microscopic disease was 12.4 mm and 1.4 mm, respectively. Following identification of these landmarks, the incidence of recurrent or persistent disease decreased (P = .02) from 5% (8 of 159) to 0% (0 of 112). CONCLUSION: The majority of pediatric patients with a TGDC will have microscopic disease in the suprahyoid area. The surgical landmark of the fascial plane between the geniohyoid and genioglossus muscles demarcates the anterior and lateral borders of resection in the suprahyoid area. This approach can be used as a reliable and easily reproducible technique in TGDC surgery to increase confidence of achieving complete removal of disease in the suprahyoid area, avoiding persistent or recurrent disease and a revision procedure.

Prospective Evaluation of a Smartphone Otoscope for Home Tympanostomy Tube Surveillance: A Pilot Study.

OBJECTIVES: Recent technological advances have led to the capability of performing high resolution imaging of the tympanic membrane. Smartphone technologies and applications have provided the opportunity to capture digital images and easily share them. The smartphone otoscope device was developed as a simple system that can convert a smartphone into a digital otoscope. This device has the prospective ability to improve physician-patient communication and assist with the diagnosis and management of ear disease. Our objective was to evaluate the feasibility and physician/parental satisfaction using the Cellscope® smartphone attachment for at home tympanostomy tube monitoring. METHODS: Children between 6 months and 15 years of age at an urban tertiary children's hospital that were scheduled for bilateral tympanostomy tube insertion or underwent bilateral tympanostomy tube surgery were prospectively enrolled in the study. Comparisons were made between parental home-recorded videos and findings during in-office otoscopy. Two independent otolaryngologists reviewed the videos and concordance between inter-rater agreements was calculated. Acceptability and use questionnaires were administered to physicians and parents. RESULTS: There was good intra-rater agreement between traditional otoscopy and video-otoscopy for tube extruding, tube blocked and tube extruded with at least 80% agreement (P < .05) and excellent inter-rater agreement between physicians for nearly all tube variables (P < .0001) There was a high degree of satisfaction with this mode of surveillance. Parents and physicians agreed that the CellScope® smartphone was easy to use, helpful with the occurrence of acute events, and appeared to improve quality of care. CONCLUSIONS: The CellScope® smartphone is feasible for use in tympanostomy tube surveillance. Use of the device may allow otolaryngologists to easily follow a child's tympanostomy tube remotely over time and offer greater parental satisfaction.

The Generalizability of the Clinical Assessment Score-15 for Pediatric Sleep-Disordered Breathing.

OBJECTIVE: The Clinical Assessment Score-15 (CAS-15) has been validated as an office-based assessment for pediatric sleep-disordered breathing in otherwise healthy children. Our objective was to determine the generalizability of the CAS-15 in a multi-institutional fashion. METHODS: Five hundred and thirty children from 13 sites with suspected sleep-disordered breathing were recruited, and the investigators completed the CAS-15. Based on decisions made in the course of clinical care, investigators recommended overnight polysomnography, observation, medical therapy, and/or surgery. Two hundred and forty-seven subjects had a follow-up CAS-15. RESULTS: Mean age was 5.1 (2.6) years; 54.2% were male; 39.1% were white; and 37.0% were African American. Initial mean (standard deviation [SD]) CAS-15 was 37.3 (12.7), n = 508. Spearman correlation between the initial CAS-15 and the initial apnea-hypopnea index (AHI) was 0.41 (95% confidence interval [CI], 0.29, 0.51), n = 212, P < .001. A receiver-operating characteristic curve predicting positive polysomnography (AHI > 2) had an area under the curve of 0.71 (95% CI, 0.63, 0.80). A score ≥ 32 had a sensitivity of 69.0% (95% CI, 61.7, 75.5), a specificity of 63.4% (95% CI, 47.9, 76.6), a positive predictive value of 88.7% (95% CI, 82.1, 93.1), and a negative predictive value of 32.9% (95% CI, 23.5, 44.0) in predicting positive polysomnography. Among children who underwent surgery, the mean change (SD) score was 30.5 (12.6), n = 201, t = 36.85, P < .001, effect size = 3.1. CONCLUSION: This study establishes the generalizability of the CAS-15 as a useful office tool for the evaluation of pediatric sleep-disordered breathing.

Advanced practice providers and children's hospital-based pediatric otolarynology practices.

INTRODUCTION: Advanced practice providers (APPs), including nurse practitioners and physician assistants, have been deployed in children's hospital-based academic pediatric otolaryngology practices for many years. However, this relationship in terms of prevalence, roles, financial consequences and satisfaction has not been examined. The objective of this study is to explore how APPs impact healthcare delivery in this setting. METHODS: Pediatric otolaryngology chiefs of all academic children's hospitals in the US were electronically surveyed about the ways APPs intersected clinically and financially in their respective practice. RESULTS: A total of 29 of 36 children's hospital-based pediatric otolaryngology practices completed the survey, of which 26 practices (90%) utilized APP. There were large variances within the APP practice cohort in faculty size (mean/median/range = 9.4/8.5/3-29); annual patient visits (mean/median = 18,373/17,600); number of practice site (mean/median/range = 4.3/4/2-9) and number of outpatient APP (mean/median/range = 6.3/5/1-30). No factors (faculty size, annual visits and number of practice sites) differentiated between the APP and non-APP practices. Among APP practices, significant correlation (p<.00001) was observed between size of APP cohort to faculty size and annual visits. 69% of the practices did not differentiate job functions of nurse practitioners and physician assistants. 85% of the practices utilized APPs in all practice sites and 19% utilized APPs in the operating room. 77% of APPs billed independently and 46% had on-site supervision. The most prevalent APP salary bracket based on 0-5, 6-10 and > 11 years of tenure were $76-100K (65%), $100-150K (77%) and $100-150K (86%), respectively. In 46% of the practices, APPs were able to generate enough revenue to cover more than 75% of their salary and 23% of practices generated a profit. 81% of the chiefs ranked the effectiveness of APPs as high (4 and 5) on a 5-point Likert scale. DISCUSSION: The majority of academic pediatric otolaryngology practices employed APPs. Despite the diversity seen in practice complexity, APP functionality and financial impact, most found the APP model to be beneficial in improving patient care, patient access and faculty productivity.

To drain or not to drain following a Sistrunk procedure: A dual institutional experience.

INTRODUCTION: A Sistrunk procedure is the standard operative management of patients with thyroglossal duct cysts. Drain placement is commonly employed with the goal of reducing postoperative complications. This study investigates the association between drain use and relevant postoperative complications following pediatric Sistrunk procedures. METHODS: Retrospective cohort study evaluating 295 pediatric patients treated between 2007 and 2016 at two tertiary care children's hospitals. RESULTS: The mean age of the study population was 5.6 years (SD 4.0). A drain was utilized in 234 cases (79.3%). The mean procedural duration was 108 min (SD 48), and significantly longer in patients receiving a drain. Early postoperative complications included seroma (5.8%), secondary infection (3.4%), wound breakdown (2.0%) and hematoma (0.3%). The risk of such complications did not significantly differ between patients without drain placement (9.8%) versus those who underwent surgical drain placement (12.0%) after accounting for age and history of preoperative infection (adjusted RR = 0.86; 95% CI: 0.37, 1.98; p = 0.72). In the subgroup analysis, findings were consistent across institutions, age category, history of infection, and primary versus secondary procedure. CONCLUSION: This dual institutional study found drain placement during a Sistrunk procedure may not reduce rates of common postoperative complications, even in longer duration cases in which a drain is more frequently placed. This data suggests a Sistrunk procedure may be safely performed without drain placement in select cases.

The incidence of revision adenoidectomy: A comparison of four surgical techniques over a 10-year period.

Approximately 130,000 adenoidectomies are performed each year in the United States. Few studies have examined adenoid regrowth and the incidence of revision surgery or have compared four different surgical instruments commonly used for adenoid surgery within the same institution. This study aimed to determine the incidence of revision adenoidectomy after the use of microdebrider, Coblation, suction cautery, and curette instruments over a 10-year period at a single major tertiary children's center in the United States. A retrospective chart review was performed for all patients who underwent primary and/or revision adenoidectomy at the Children's Hospital Los Angeles (CHLA) between August 2004 and August 2014. During the 10-year study period, a microdebrider was used in 212 cases, Coblation in 382, suction cautery in 1,926, and curette in 3,139 adenoidectomies. The percentages of revision adenoidectomy were 1.42% (3 patients) for microdebrider, 0.79% (3 patients) for Coblation, 0.36% (7 patients) for suction cautery, and 0.03% (1 patient) for curette. The cumulative incidence of revision adenoidectomy for initial surgeries performed at CHLA was 0.2% for the 10-year study period. Pearson chi-square analysis showed statistically significant differences between the surgical techniques (p < 0.0001). In conclusion, regrowth of adenoid tissue requiring revision surgery occurs very infrequently irrespective of the instrument used for the primary procedure, and the most common indication for revision adenoidectomy is to improve eustachian tube dysfunction rather than nasal obstruction due to adenoid hypertrophy.

Paranasal Rosai-Dorfman Disease with Osseous Destruction.

Rosai-Dorfman disease is a rare histiocytic proliferative disorder of unknown etiology typically characterized by cervical lymphadenopathy. Extranodal involvement often manifests in the head and neck region. We present a 10-year-old male who presented to our hospital with left epiphora from an aggressive paranasal mass invading the left orbit with osseous destruction. The mass was surgically biopsied and debulked with histopathological examination revealing Rosai-Dorfman disease. Although rarely found in the sinuses, Rosai-Dorfman disease should be considered when evaluating sinonasal masses.

Histopathologic Finding of Both Gastric and Respiratory Epithelia in a Lingual Foregut Cyst.

Foregut cysts are uncommon, mucosa-lined congenital lesions that may occur anywhere along the gastrointestinal or respiratory tract and typically present within the first year of life. Although infrequent, these cysts may generate feeding or respiratory difficulties depending on the size and location of the lesion. Foregut cysts of the oral cavity are rarely seen and of those cases localized to the tongue are even more uncommon. We describe a 4-month-old girl with a foregut cyst involving the floor of mouth and anterior tongue. Subsequent histologic analysis demonstrated a cyst lined with both gastric and respiratory epithelia. This case represents an extremely rare finding of both gastric and respiratory epithelia lined within a single cystic structure in the tongue. Although a very rare finding, a foregut cyst should be on the differential diagnosis of any lesion involving the floor of mouth or tongue in an infant or child.

Thyroglossal duct remnant surgery: a reliable, reproducible approach to the suprahyoid region.

BACKGROUND: Recurrence of thyroglossal duct remnants remains a clinical problem despite the success of the Sistrunk procedure. Inadequate excision of disease in the suprahyoid region significantly impacts disease recurrence. The primary aim of this study is to describe and present the author's experience with a simple, reliable, and reproducible approach to the suprahyoid area in a Sistrunk procedure. METHODS: A retrospective review of the surgical management of thyroglossal duct remnants by a single surgeon at the Children's Hospital Los Angeles over a 16-year period was performed. Demographic and clinical data including disease recurrence and other complications were collected. Recurrence rates before and after the consistent application of a modified Sistrunk procedure were compared. RESULTS: 94 patients (54% female and 46% male; mean age 5.2 years) met the inclusion criteria for this study. Overall recurrence rate following a Sistrunk procedure was 2.2%; 11.1% prior to 2004 and 0% after 2004, following consistent implementation of the surgical approach to the suprahyoid region as detailed in this study. Complications were minor and mean follow-up was 5.4 months. CONCLUSIONS: The author has described a simple, reproducible, and reliable approach to the suprahyoid area in a Sistrunk procedure that limits incomplete excision with minimal risk for complications. This approach to the suprahyoid region should be considered for routine use in the management of both primary and revision thyroglossal duct remnants.

Thyroglossal duct cyst and sinuses: a 20-year Los Angeles experience and lessons learned.

BACKGROUND: First described in 1920 and later modified in 1928, the Sistrunk procedure substantially reduced the incidence of recurrence of midline neck cysts compared with a local excision or cystectomy. The purpose of this study was to determine if the rate of recurrence was influenced by performing either a 'classic' or a 'modified' Sistrunk procedure, if the recurrence rate was influenced by the physician's training, how successful we have been in managing patients with a recurrence? Finally, is outpatient surgery safe for Sistrunk procedures? METHODS: We performed a retrospective review of all patients with a thyroglossal duct remnant (TGDR) who were seen at the Children's Hospital Los Angeles (CHLA) from 1990 to 2010. The following data were collected: patient age, gender, presence or absence of a pre-operative infection, imaging studies, type of procedure performed, the attending surgeon's training background, inpatient or outpatient status, and complications. RESULTS: A total of 128 patients (61% male, 39% female) met the inclusion criteria. The age ranged from 2 months to 14 years (mean of 5.1 years). A total of 137 procedures were performed; 114 (83.2%) for primary and 23 (16.8%) for secondary disease. Complications included post-operative infection (10.9%), recurrence of disease (6.6%), undesirable scar (5.8%), and fistula (2.9%). Surgeons with fellowship-training in pediatric otolaryngology had a recurrence rate of 4.0% and surgeons with fellowship-training in pediatric surgery or pediatric plastic surgery had a recurrence rate of 30.1%. Twenty patients had a 'classic' Sistrunk (14.6%) and 117 (85%) had a 'modified' procedure. Patients were admitted after surgery in 78 cases (56.9%) and 59 patients (43.1%) had an outpatient (OPD) procedure. CONCLUSIONS: There is no place for cystectomy in the treatment of TGDR. A 'modified' Sistrunk procedure is the procedure of choice in both primary and revision cases. Wide local excision of recurrences is required and a 'classic' Sistrunk should be considered. Specific training to gain an intimate knowledge of the anatomy in and around the larynx and experience with multiple cases reduces the incidence of recurrence. Outpatient surgery is safe and effective for selected patients who undergo a Sistrunk procedure.

Histologic assessment of thermal injury to tonsillectomy specimens: a comparison of electrocautery, coblation, harmonic scalpel, and tonsillotome.

OBJECTIVES/HYPOTHESIS: To determine the extent of thermal injury to the tonsillar tissue following the use of various types of instrumentation. To determine if tonsillectomy specimens routinely contain tissue other than lymphoid tissue. STUDY DESIGN: Retrospective histologic analysis. METHODS: A histologic analysis performed on 228 tonsillectomy specimens removed by use of an electrocautery in 132 specimens, harmonic scalpel in 46, coblation device in 24, and a tonsillotome in 26. The specimens were evaluated for presence and percentage of skeletal muscle and depth of thermal tissue injury. RESULTS: The mean percentage of skeletal muscle present in the specimens was 0.79% for electrocautery, 1.74% for harmonic scalpel, 0.97% for coblation device, and 1.66% for the tonsillotome. Skeletal muscle was absent in only 8 of 228 specimens (3.5%). Electrocautery has a statistically significant (P < .05) lower percentage of muscle tissue compared to harmonic scalpel and the tonsillotome. There was no statistically significant difference in the mean depth of thermal injury among the harmonic scalpel (0.68 mm), electrocautery (0.58 mm), and coblation device (0.71 mm) specimens. The tonsillotome specimens had no thermal injury. CONCLUSIONS: Attempts to remove the entire tonsil results in a similar depth of thermal injury to tonsillectomy specimens when using the harmonic scalpel, electrocautery, and coblation device. Skeletal muscle is a nearly ubiquitous finding in routine tonsillectomy specimens. The use of an electrocautery with a needle point may allow for a more precise dissection as it results in tonsillectomy specimens with a smaller percentage of muscle present.

Age specific differences in pediatric obstructive sleep apnea.

BACKGROUND: Some have suggested that younger children have a more severe form of obstructive sleep apnea than older children and therefore are at a higher risk for respiratory compromise after tonsillectomy and adenoidectomy. However, at present there are few studies that have identified any significant correlation between age and severity of obstructive sleep apnea. OBJECTIVE: To determine if age specific differences in obstructive sleep apnea are present in children. DESIGN: Retrospective chart review. SETTING: Tertiary care children's hospital. PATIENTS: The records of children (1-18 years of age) with obstructive sleep apnea diagnosed by overnight polysomnography between January 1998 and January 2001 were reviewed. Children included in the study also had evidence of adenotonsillar hypertrophy and had no other co-existing medical problems. MAIN OUTCOME MEASURES: Overnight polysomnography was performed in all children. Apnea-hypopnea index (AHI), baseline and lowest O(2) saturation, baseline and peak end tidal CO(2), and total number of obstructive apneas, hypopneas, central apneas and mixed apneas were measured during each polysomnogram. Children were subdivided into the following age groups: 1-2, 3-5, 6-11 and 12-18 years. Polysomnograms were classified into normal, mild, moderate and severe categories. RESULTS: Three hundred and sixty-three children were studied; 45 children were ages 1-2 years, 159 children were ages 3-5 years, 137 children were 6-11 years and 22 children were 12-18 years. Although there appears to be a trend towards a greater mean number of obstructive apneas, hypopneas, central apneas, mixed apneas, a higher mean AHI, lower mean SaO(2) nadir, and a higher mean PETCO(2) in the younger age groups when compared to the older groups, a Student's t-test demonstrates that there is no statistical significance for most OSA parameters. An analysis of variance using the F-test reveals statistical significance (p<0.01) when children ages 1-2 were compared to those 3-5, 6-11 or 12-18 years of age for the variables AHI, mean number of central apneas, hypopneas and mixed apneas. When comparing patients in the various severity categories, children ages 1-2 years show a distinct distribution with a larger percentage in the moderate to severe categories. Chi square analysis reveals a significant difference between the frequency distribution of children in age group 1-2 years and that of the other age groups (p<0.01). CONCLUSION: There is a predilection for children less than 3 years of age to have more severe obstructive sleep apnea as documented by polysomnography. Central apnea also appears to be more common in this age group. These findings may be explained by anatomic and physiologic differences related to age and support a period of observation following adenotonsillectomy in younger children.

Histologic analysis of pediatric tonsil and adenoid specimens: is it really necessary?

OBJECTIVE: To evaluate the incidence of unexpected histologic findings in routine tonsillectomy and adenoidectomy specimens. METHODS: A retrospective medical record review was performed at a tertiary care children's hospital. The pathology records of 2062 children who underwent tonsil or adenoid surgery were analyzed and the final histologic diagnosis was recorded. RESULTS: Four unexpected histologic findings were found on routine tonsil and adenoid specimens. None were clinically significant. A review of the literature shows a very low rate (0.015%) of unexpected clinically significant diagnoses in pediatric adenotonsillectomy specimens. CONCLUSIONS: Given rarity of unexpected clinically significant diagnoses in pediatric adenotonsillectomy specimens, the cost and effort of analyzing each specimen histologically is difficult to justify.

History of pediatric laryngotracheal reconstruction.

In the early twentieth century, John Winslow wrote that there was no more difficulty in laryngology than treating chronic stenosis of the larynx and trachea. Winslow described cases as "excessively rebellious to treatment" and treatment requiring "patience, persistence, self-sacrifice and skill on the part of the surgeon" and "discomfort or even suffering by the patient." Three decades later, Chevalier Jackson wrote that curing patients required perseverance over a period of time rarely as short as 3 months and as long as 7 years. Significant strides in surgical technique have been made; this article chronicles the development of laryngotracheal reconstruction in children.
