A single center retrospective comparison of post-tonsillectomy hemorrhage between BiZact and Coblator.

INTRODUCTION: Over 550,000 tonsillectomies are performed every year. While post-tonsillectomy hemorrhage (PTH) has been studied in the coblator, bovie, and cold steel technique, there is a dearth of studies examining the post-tonsillectomy outcome using BiZact. This study examines the rate of BiZact PTH requiring control of hemorrhage in the OR and assess resident comfort using the device. METHODS: Retrospective chart review for all tonsillectomies performed between January 2018 and December 2020 were performed. Rates of PTH were analyzed. In addition, a 7-question BiZact resident experience survey was administered to 25 otolaryngology residents. RESULTS: 1384 patients were included in this study; 444 (32%) Bizact and 940 (68%) Coblation. 11 (2.48%) BiZact patients had PTH requiring OR for control of hemorrhage, compared to 44 (4.68%) Coblation patients. There were no patient deaths because of PTH. The mean age of patients with PTH was 7.44 (SD 4.07) years old. 22 (88%) residents responded to the survey. 17 (77.27%) felt more confident with Coblator while performing tonsillectomy most commonly reported for ease of use, followed by BiZact 4 (18.18%), most commonly reported for improved surgical plane. CONCLUSION: BiZact is a safe and effective addition. At our institution, the rate of secondary PTH requiring OR intervention for BiZact is comparable to the national average for other tonsillectomy devices. The rate of BiZact PTH requiring OR intervention in our experience was nearly half of those done with Coblator. Overall residents at SCHC preferred Coblator over BiZact mainly attributed to Coblator's versatility and ability to control intraoperative tonsil bleeding without additional instruments despite BiZact's shorter operative time.

A follicular regulatory Innate Lymphoid Cell population impairs interactions between germinal center Tfh and B cells.

Innate Lymphoid Cells (ILCs) are immune cells typically found on mucosal surfaces and in secondary lymphoid organs where they regulate the immune response to pathogens. Despite their key role in the immune response, there are still fundamental gaps in our understanding of ILCs. Here we report a human ILC population present in the follicles of tonsils and lymph nodes termed follicular regulatory ILCs (ILCFR) that to our knowledge has not been previously identified. ILCFR have a distinct phenotype and transcriptional program when compared to other defined ILCs. Surprisingly, ILCFR inhibit the ability of follicular helper T (Tfh) cells to provide B cell help. The localization of ILCFR to the germinal centers suggests these cells may interfere with germinal center B cell (GC-B) and germinal center Tfh cell (GC-Tfh) interactions through the production of transforming growth factor beta (TGF-ß. Intriguingly, under conditions of impaired GC-Tfh-GC-B cell interactions, such as human immunodeficiency virus (HIV) infection, the frequency of these cells is increased. Overall, we predict a role for ILCFR in regulating GC-Tfh-GC-B cell interactions and propose they expand in chronic inflammatory conditions.

Speech and Language Outcomes in Patients with Ankyloglossia Undergoing Frenulectomy: A Retrospective Pilot Study.

Ankyloglossia is a controversial topic with no standardized treatment guidelines. A retrospective chart review was conducted to identify children who underwent lingual frenulectomy for speech and language impairment. Impairment severity was recorded pre- and postoperatively as mild, mild to moderate, moderate, moderate to severe, or severe. Variables were tested with chi-square analysis for their statistical relationship to improvements in speech and language. Children with preoperative moderate and moderate-to-severe speech and language impairment attained better speech and language outcomes after frenulectomy as compared with children with mild and mild-to-moderate impairment (100% vs 82%, P = .015). Sutured closure after frenulectomy was associated with better speech and language improvements (100% vs 83%, P = .033). One could consider observation of patients with mild and mild-to-moderate speech and language impairments. Sutured closure might result in better improvements in speech and language impairments. This pilot study sheds light on the potential impact of a larger study currently underway.

Caregiver perception of speech quality in patients with ankyloglossia: Comparison between surgery and non-treatment.

OBJECTIVES: Our objective was to determine if there are differences in caregiver perception of speech for patients that undergo frenulectomy compared to patients that were not surgically treated. INTRODUCTION: Ankyloglossia is a controversial topic without standardized treatment guidelines. Although there have been several studies suggesting that breastfeeding does improve after frenulectomy, there is a paucity of literature that investigates the relationship between ankyloglossia and speech. METHODS: A retrospective chart review was conducted to identify patients with ankyloglossia. Patients were categorized into surgical treatment (frenulectomy) and non-treatment groups. Caregivers of both groups were contacted by phone and surveyed on speech quality and tongue mobility using Likert scores. Mann Whitney-U testing was used to determine if there were significant differences in perceived speech quality between the surgical and non-surgical groups. RESULTS: The caregivers of seventy-seven patients participated in the phone survey: 46 (60%) children in the surgical group and 31 (40%) children in the non-surgical group who participated in the phone survey. There were no differences in difficulty with speech (p = 0.484) and tongue mobility (p = 0.064) between the two groups. However, patients that underwent surgical intervention for ankyloglossia reported less difficulty with tongue tasks (p < 0.001) compared to those who were not surgically treated. Additionally, 50% of patients that underwent surgery had a documented family history of ankyloglossia which was significantly higher than 16.1% in the non-surgical group (p = 0.002). CONCLUSIONS: It appears that children with ankyloglossia might have similar speech quality following frenulectomy in comparison to speech quality without treatment. Children who undergo frenulectomy may experience improvements in tongue tasks. This data should encourage further research on the management of speech concerns in children with ankyloglossia.

Hyoid bone and laryngeal movement dependent upon presence of a tracheotomy tube.

The aim of this prospective, consecutive study was to investigate the biomechanical effects, if any, of the presence of a tracheotomy tube and tube cuff status, tube capping status, and aspiration status on movement of the hyoid bone and larynx during normal swallowing. Seven adult patients (5 male, 2 female) with an age range of 46-82 years (mean = 63 years) participated. Criteria for inclusion were no history of cancer of or surgery to the head and neck (except tracheotomy), normal cognition, normal swallowing, and ability to tolerate decannulation. Digital videofluoroscopic swallowing studies were performed at 30 frames/s and with each patient seated upright in the lateral plane. Variables evaluated included maximum hyoid bone displacement and larynx-to-hyoid bone approximation under three randomized conditions: tracheotomy tube in and open with a 5-cc air-inflated cuff; tracheotomy tube in and capped with deflated cuff; and tracheotomy tube out (decannulated). Differences between maximum hyoid bone displacement and larynx-to-hyoid approximation (cm) based on presence/absence of a tracheotomy tube, tube cuff status, and tube capping status were analyzed with the Student's t test. Reliability testing with a Pearson product moment correlation was performed on 21% of the data. No significant differences (p > 0.05) were found for both maximum hyoid bone displacement and larynx-to-hyoid bone approximation during normal swallowing based on tracheotomy tube presence, tube cuff status, or tube capping status. Intraobserver reliability for combined measurements of maximum hyoid displacement and larynx-to-hyoid approximation was r = 0.97 and interobserver reliability for the absence of aspiration was 100%. For the first time with objective data it was shown that the presence of a tracheotomy tube did not significantly alter two important components of normal pharyngeal swallow biomechanics, i.e., hyoid bone movement and laryngeal excursion. The hypothesis that a tracheotomy tube tethers the larynx thereby preventing hyoid bone and laryngeal movement during normal swallowing is not supported.

Contralateral platysma suspension: an adjunct to rhytidectomy.

As we age, a number of factors distort the contour of the cervicomental angle. Submental adipose deposits, anterior laxity of the platysma muscle, and relaxation of cervical skin contribute to this undesirable result. Comprehensive rhytidectomy will frequently involve enhancement of the cervicomental angle as an adjunctive procedure. Facial aesthetic surgeons have devised numerous techniques to deal with the aging neck. Commonly, the approach combines submental adipose tissue excision with posterosuperior-based support, either by preauricular or postauricular incision. Herein, we describe a technique incorporating standard submental suction lipectomy with a novel method of contralateral midline platysma suspension that creates a dynamic support system involving both rigid suture-based and flexible muscle-based components. This technique delivers quality aesthetic results and superior postoperative patient satisfaction.

Radiofrequency volume tissue reduction of the tonsils: case report and histopathologic findings.

Innovative new techniques to resect tonsillar tissue have been described in the recent literature. We report the case of a patient who underwent volume reduction of tonsillar tissue by radiofrequency energy under local anesthesia in an office setting. Treatment resulted in a reduction of tonsillar size with minimal pain, which can be attributed to the avoidance of mucosal interruption. The patient subsequently underwent standard tonsillectomy, which allowed us to examine the histopathology of the tissue that was treated with radiofrequency. In doing so, we noted an absence of fibrosis and preservation of normal histologic architecture. We conclude that performing volume reduction of tonsillar tissue by applying radiofrequency energy to the stroma of the tonsils without temperature control results in objective improvement in airway size with minimal effects on the histopathology of the tonsillar stroma. Mucosa-sparing tonsillar reduction may be a preferable alternative to other techniques of tonsillar reduction, especially for young children, who would experience a nearly pain-free procedure.
