AbstractObjectiveTo develop a convolutional neural network‐based computer vision model to recognize and track 2 mastoidectomy surgical instruments—the drill and the suction‐irrigator—from intraoperative video recordings of mastoidectomies.Study DesignTechnological development and model validation.SettingAcademic center.MethodsTen 1‐minute videos of mastoidectomies done for cochlear implantation by varying levels of resident surgeons were collected. For each video, containing 900 frames, an open‐access computer vision annotation tool was used to annotate the drill and suction‐irrigator class images with bounding boxes. A mastoidectomy instrument tracking module, which extracts the center coordinates of bounding boxes, was developed using a feature pyramid network and layered with DETECTRON, an open‐access faster—region‐based convolutional neural network. Eight videos were used to train the model, and 2 videos were used for testing. Outcome measures included Intersection over Union (IoU) ratio, accuracy, and average precision.ResultsFor an IoU of 0.5, the mean average precision for the drill was 99% and 86% for the suction‐irrigator. The model proved capable of generating maps of drill and suction‐irrigator stroke direction and distance for the entirety of each video.ConclusionsThis computer vision model can identify and track the drill and suction‐irrigator from videos of intraoperative mastoidectomies performed by residents with excellent precision. It can now be employed to retrospectively study objective mastoidectomy measures of expert and resident surgeons, such as drill and suction‐irrigator stroke concentration, economy of motion, speed, and coordination, setting the stage for characterization of objective expectations for safe and efficient mastoidectomies.

Objective To characterize the opioid prescribing patterns for and requirements of patients undergoing repair of spontaneous cerebrospinal fluid (sCSF) leaks of the lateral skull base. Study Design Retrospective chart review. Setting Tertiary referral center. Patients Adults with lateral skull base sCSF leaks who underwent repairs between September 1, 2014, and December 31, 2020. Main Outcome Measure Mean morphine milligram equivalents (MMEs) of opioids dispensed to inpatients and prescribed at discharge, additional pain control medications dispensed, and outpatient additional opioid requests were compared between groups. Results Of 78 patients included, 46 (59%) underwent repair via a transmastoid (TM), 6 (7.7%) via a middle cranial fossa (MCF), and 26 (33.3%) via a combined TM–MCF approach. Inpatients received a mean of 21.3, 31.4, and 37.6 MMEs per day during admission for the TM, MCF, and combined TM–MCF approaches, respectively (p = 0.019, ηp2 = 0.101). Upon discharge, nearly all patients (n = 74, 94.9%) received opioids; 27.3, 32.5, and 37.6 MMEs per day were prescribed after the TM, MCF, and TM–MCF approaches, respectively (p = 0.015, ηp2 = 0.093). Five (6.4%) patients requested additional outpatient pain medication, after which three were prescribed 36.7 MMEs per day. Patients with idiopathic intracranial hypertension required significantly more inpatient MMEs than those without (41.5 versus 25.2, p = 0.02, d = 0.689), as did patients with a history of headaches (39.6 versus 23.6, p = 0.042, d = 0.684). Conclusions Patients undergoing sCSF leak repair via the MCF or TM–MCF approaches are prescribed more opioids postoperatively than patients undergoing the TM approach. Patients with a history of headaches or idiopathic intracranial hypertension might require more opioids postoperatively.

AbstractObjectiveTo determine if simultaneous administration of acoustic vibration and oscillating expiratory pressure affects the severity of facial pain among patients with complaint of “sinus headache”.MethodsThis is a prospective single‐arm observational study performed at a tertiary care medical center. Subjects with complaint of sinus headache without evidence of chronic rhinosinusitis on exam or computed tomography participated in a clinical study applying simultaneous acoustic vibrations and positive expiratory pressure to the nasal cavity twice daily over 4 weeks. Efficacy was assessed using three validated pain metrics—pain visual analog scale (VAS), brief pain inventory‐short form (BPI‐SF), and McGill pain questionnaire‐short form (MPQ‐SF). Device safety and patient satisfaction were also assessed using questionnaires.ResultsTwenty‐nine patients (mean age 49 years, 55% female) completed the study without any major adverse events. At the 4 week follow‐up, facial pain VAS improved from mean ± SD of 59.6 ± 15.7 to 34.6 ± 21.7 (p < .001), BPI mean pain (mean ± standard deviation) improved from 4.4 ± 2.0 to 2.9 ± 1.9 (p = .007), and MPQ‐SF total improved from 12.2 ± 6.5 to 6.5 ± 5.2 (p < .001) with approximately 70% of patients achieving a minimal clinically important difference (MCID) across all metrics. Additionally, pain VAS was assessed 5 min after a single use at baseline with significant improvement (p < .001). Eighty‐six percent of subjects would both use device again and recommend it to others.ConclusionsSimultaneous administration of acoustic vibration and oscillating expiratory pressure appears to be a safe treatment for sinus headaches in patients without objective evidence of chronic sinusitis. Results from this initial study are promising with regard to efficacy in treatment of sinus headaches but will require further study.Level of evidence2c.

Abstract Background Cystic fibrosis (CF) is a multisystem disease that often requires otolaryngology care. Individuals with CF commonly have chronic rhinosinusitis but also present with hearing loss and dysphonia. Given these manifestations of CF, otolaryngologists are frequently involved in the care of patients with CF; however, there is limited consensus on optimal management of sinonasal, otologic, and laryngologic symptoms. Methods The Cystic Fibrosis Foundation convened a multidisciplinary team of otolaryngologists, pulmonologists, audiologists, pharmacists, a social worker, a nurse coordinator, a respiratory therapist, two adults with CF, and a caregiver of a child with CF to develop consensus recommendations. Workgroups developed draft recommendation statements based on a systematic literature review, and a ≥80% consensus was required for acceptance of each recommendation statement. Results The committee voted on 25 statements. Eleven statements were adopted recommending a treatment or intervention, while five statements were formulated recommending against a specific treatment or intervention. The committee recommended eight statements as an option for select patients in certain circumstances, and one statement did not reach consensus. Conclusion These multidisciplinary consensus recommendations will help providers navigate decisions related to otolaryngology consultation, medical and surgical management of CF‐CRS, hearing, and voice in individuals with CF. A collaborative and multidisciplinary approach is advocated to best care for our patients with CF. Future clinical research is needed utilizing standardized, validated outcomes with comprehensive reporting of patient outcome, effects of modulator therapies, and genetic characteristics to help continue to advance care, decrease morbidity, and improve the quality of life for individuals with CF.
