Six-week postoperative opioid use and pain following a randomized controlled trial evaluating multimodal analgesia for head and neck free flap patients.

Introduction: Head and neck malignancy treatment often involves invasive surgeries, necessitating effective postoperative pain control. However, chronic reliance on opioid medications remains a challenge for many patients after surgery. Multimodal analgesia (MMA) within enhanced recovery after surgery protocols has shown success in limiting narcotic pain medications for other cancer types. In a prior study, MMA comprising acetaminophen, ketorolac, gabapentin, and a neurogenic block reduced opioid use in the 7-day postoperative period for major head and neck reconstructive surgery. This study investigates the impact of multimodal analgesia on opioid prescription and pain during the 6-week postoperative period for patients undergoing major head and neck oncologic surgeries, aiming to understand the longer-term effects of narcotic use. Methods: The study retrospectively examined participants in a [hybrid type 1 effectiveness-implementation pragmatic trial to assess multimodal analgesia's long-term effectiveness in head and neck free flap surgery. Arm A received scheduled acetaminophen and as-needed opioids, while Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the donor site, scheduled acetaminophen, and as-needed opioids. Retrospective data collection included opioid prescription use and pain scores up to 6 weeks after surgery, gathered from the Kansas prescription drug monitoring program, K-TRACS. Results: Thirty patients participated, 14 in Arm A and 16 in Arm B. The average morphine milligram equivalents per day of filled prescriptions were not significantly different between Arm A and Arm B (7.23 vs. 7.88, p = .845). Additionally, average pain scores at 6 weeks showed no significant difference between the two groups (1.4 vs. 1.9, p = .612). Conclusion: Patients with head and neck cancer treated with multimodal analgesia during the perioperative period did not exhibit significant differences in opioid use and pain within 6 weeks after discharge. To confirm these findings, a re-examination with strict measures of opioid use and scheduled pain assessments in a prospective manner is warranted. Level of Evidence: 4.

The Use of Dissemination and Implementation to Improve Multimodal Analgesia in Head and Neck Surgery.

OBJECTIVES: To optimize the delivery of multimodal analgesia to patients undergoing major head and neck oncologic surgeries. METHODS: Pilot study included patients enrolled to receive either scheduled acetaminophen and as-needed opioids (control group) or scheduled acetaminophen, gabapentin, ketorolac, and as-needed opioids (experimental group). RCT, a hybrid type 1 effectiveness-implementation pragmatic trial, was designed to test the effectiveness of the intervention. Arm A received scheduled acetaminophen and as-needed opioids. Arm B received scheduled gabapentin, ketorolac, a regional nerve block at the free tissue donor site, scheduled acetaminophen and as-needed opioids. RESULTS: Pilot: Thirty-one patients undergoing major head and neck surgery were enrolled. Mean MMEs administered in control group (n = 15) was 251.60 mg (SD = 224.57 mg); mean MMEs in Experimental group (n = 16) was 195.78 mg (SD = 131.08 mg), p = 0.401. LOS was 8.0 days in control versus 7.0 days in experimental group (p = 0.054). RCT: Interim analysis for safety and futility was planned during trial's design after 30 patients (n = 14 Arm A, and n = 16 Arm B). Mean MMEs administered were 135.1 mg in Arm A, (SD = 86.0 mg) versus mean MME of 51.3 mg in Arm B (SD = 43.3 mg, (p < 0.05)). Given clear superiority results, the trial was prematurely terminated. Functional pain scores, LOS, and complications were similar between the arms (p > 0.05). Variability of mean MME was compared before and after implementation of the management protocols: SD in RCT#1 was 181.46 mg versus 124.6 mg in RCT#2. CONCLUSION: Multimodal analgesia significantly reduced the need for opioids in patients undergoing major head and neck surgery.

Resident Education in Laryngeal Stroboscopy: Part II-Evaluation of a Multimedia Training Module.

OBJECTIVE: To evaluate the efficacy of a web-based training module for teaching interpretation of laryngeal stroboscopy in a cohort of otolaryngology residents. STUDY DESIGN: Randomized controlled trial. SETTING: Academic tertiary center. SUBJECTS AND METHODS: Residents from three training programs were invited to complete an assessment consisting of a survey and five stroboscopic exams. Subsequently, participants were randomized to receive teaching materials in the form of (1) a handout (HO) or (2) a multimedia module (MM) and asked to complete a post-training assessment. Responses were compared to responses provided by three fellowship-trained laryngologists. RESULTS: Thirty-five of 47 invited residents (74.4%) completed both assessments. Overall mean postassessment scores were 64.3% ± 7.0, with the MM group (67.0% ± 7.6, n = 17) scoring higher (P = 0.03) than the HO (61.6% ± 5.4, n = 18) cohort. Postassessment scores did not differ by postgraduate year (P = 0.75) or institution (P = 0.17). Paired analysis demonstrated an overall mean improvement of 7.4% in the handout (HO) cohort (P = 0.03) and 10.3% in the MM cohort (P = 0.0006). Subset analysis demonstrated higher scores for the MM cohort for perceptual voice evaluation (HO = 68.8% ± 11.0; MM = 77.3% ± 10.6, P = 0.03) and stroboscopy-specific items (HO = 55.5% ± 8.2; MM = 61.9% ± 10.8, P = 0.06). On a five-point Likert scale, residents reported improved confidence in stroboscopy interpretation (P < 0.0001), irrespective of cohort (P = 0.62). Residents rated the MM (median = 5) more favorably as a teaching tool compared to the HO (median = 4, P = 0.001). CONCLUSION: Use of both the written HO and MM module improved scores and confidence in interpreting laryngeal stroboscopy. The MM was more effective in perceptual voice evaluation and stroboscopy-specific items. The MM was also rated more favorably by residents and may be an ideal adjunct modality for teaching stroboscopy.

Resident Education in Laryngeal Stroboscopy and Perceptual Voice Evaluation: An Assessment.

OBJECTIVES: To evaluate otolaryngology residents' level of confidence and understanding in interpreting laryngeal stroboscopy. METHODS: Otolaryngology residents from three residency programs with fellowship-trained laryngologists on faculty were invited to participate. An assessment consisting of a survey and five stroboscopic exams was administered. Each exam consisted of questions on perceptual voice evaluation, laryngoscopic findings, and stroboscopic findings. Scores were compared to answers provided by three fellowship-trained laryngologists. RESULTS: Thirty-eight of 47 invited residents (80.8%) enrolled in the study. On a five-point likert scale, residents reported low confidence (median = 2, range = 1-4) in interpreting stroboscopy, regardless of training program (P = 0.81). Mean assessment scores were 56.5% ± 11.9, with scores in perceptual voice evaluation = 68.5% ± 10.6; laryngoscopy = 70.2% ± 12.8; and stroboscopy = 45.3% ± 17.8. Residents performed worse on stroboscopy questions compared to laryngoscopy questions (P < 0.0001). There was a significant difference in scores by postgraduate year (P = 0.03), but not by institution (P = 0.34). A moderately positive correlation between reported level of confidence and overall scores (ρ = .47, P = 0.003) was demonstrated. CONCLUSIONS: Despite didactic and clinical exposure, residents report low confidence in interpreting stroboscopy and scored lower on stroboscopy-specific questions compared to other assessment items. Additional resources and learning opportunities are needed to improve resident confidence and comprehension of stroboscopy.

Comparative Anatomy of the Mammalian Corneal Subbasal Nerve Plexus.

Purpose: The subbasal nerve plexus (SNP) is the densest and most recognizable component of the mammalian corneal innervation; however, the anatomical configuration of the SNP in most animal models remains incompletely described. The purpose of the current study is to describe in detail the SNP architecture in eight different mammals, including several popular animal models used in cornea research. Methods: Corneal nerves in mouse, rat, guinea pig, rabbit, dog, macaque, domestic pig, and cow eyes were stained immunohistochemically with antiserum directed against neurotubulin. SNP architecture was documented by digital photomicrography and large-scale reconstructions, that is, corneal nerve maps, using a drawing tube attached to a light microscope. Results: Subbasal nerve fibers (SNFs) in mice, rats, guinea pigs, dogs, and macaques radiated centrally from the corneoscleral limbus toward the corneal apex in a whorl-like or spiraling pattern. SNFs in rabbit and bovine corneas swept horizontally across the ocular surface in a temporal-to-nasal direction and converged on the inferonasal limbus without forming a spiral. SNFs in the pig cornea radiated centrifugally in all directions, like a starburst, from a focal point located equidistant between the corneal apex and the superior pole. Conclusions: The results of the present study have demonstrated for the first time substantial interspecies differences in the architectural organization of the mammalian SNP. The physiological significance of these different patterns and the mechanisms that regulate SNP pattern formation in the mammalian cornea remain incompletely understood and warrant additional investigation.

Extra-ocular movement restriction and diplopia following orbital fracture repair.

PURPOSE: To report a series of patients with extra-ocular movement restriction and diplopia after orbital fracture repair, and determine the effect of timing of repair and the type of implant used. METHODS: A chart review was conducted identifying all patients >18years of age at our institution between June 2005 and June 2008 who underwent orbital fracture repair, and presented with clinically significant diplopia and extra-ocular movement restriction persisting longer than one month after repair. Data collected included timing of repair, implant used within the orbit, and need for revision. RESULTS: Ten patients were identified with a mean time to primary orbital fracture repair at 9days (range 1-48). Seven patients underwent revision of their orbital fracture repair with removal of the previously placed implant and replacement with non-porous 0.4mm Supramid Foil, whereas one patient underwent lateral and inferior rectus recessions without revision of primary fracture repair. Titanium mesh was the intra-orbital implant found in all patients requiring revision of orbital fracture repair. All revisions resulted in resolution of clinically significant diplopia. CONCLUSIONS: Clinically significant diplopia and extra-ocular movement restriction is not an uncommon complication after orbital fracture repair. In our series, there was a strong association between these complications and the use of porous titanium mesh implants. Revision of fractures significantly improved diplopia in all but one patient. This suggests that meticulous fracture repair and the use of non-porous implants primarily or secondarily may preclude the need for strabismus surgery after orbital trauma.

Surgical repair of spontaneous cerebrospinal fluid (CSF) leaks: A systematic review.

Objectives: To review the safety and efficacy of surgical management for spontaneous cerebrospinal fluid (CSF) leaks of the anterior and lateral skull base. Data Sources: A systematic review of English articles using MEDLINE. Review Methods: Search terms included spontaneous, CSF, cerebrospinal fluid, endoscopic, middle fossa, transmastoid, leak, rhinorrhea. Independent extraction of articles by 3 authors. Results: Patients with spontaneous CSF leaks are often obese (average BMI of 38 kg/m2) and female (72%). Many patients also have obstructive sleep apnea (∼45%) and many have elevated intracranial pressure when measured by lumbar puncture. In addition to thinning of the skull base, radiographic studies also demonstrate cortical bone thinning. Endoscopic surgical repair of anterior skull base leaks and middle cranial fossa (MCF) approach for repair of lateral skull base leaks are safe and effective with an average short-term failure rate of 9% and 6.5%, respectively. Long-term failure rates are low. One randomized trial failed to show improved success of anterior leak repairs with the use of a lumbar drain (LD) (95% with vs. 92% without; P = 0.2). In a large retrospective cohort of MCF lateral skull base repairs, perioperative LD use was not necessary in >94% of patients. Conclusions: Spontaneous CSF leaks are associated with female gender, obesity, increased intracranial hypertension, and obstructive sleep apnea. Endoscopic repair of anterior skull base leaks and MCF or transmastoid approaches for lateral skull base leaks have a high success rate of repair. In most cases, intraoperative placement of lumbar drain did not appear to result in improved success rates for either anterior or lateral skull base leaks. Level of Evidence: 2a, Systematic Review.

Rapidly enlarging low-grade fibromyxoid sarcoma with intracranial extension in a 5-year-old girl: case report.

Low-grade fibromyxoid sarcoma (LGFMS) is a rare mesenchymal tumor that is characterized by a benign histology but potentially aggressive clinical behavior, with a high rate of recurrence and metastasis. It primarily occurs in young adults in the extremities, inguinal area, neck, or chest wall. There are rare reports of intracranial LGFMS in adults. In this report, the authors present the case of a 5-year-old girl who presented with a rapidly enlarging frontal scalp mass. Pathological examination of the resected mass demonstrated LGFMS. To the authors' knowledge, this is the only reported case of intracranial LGFMS in a child.

Analysis of long-term (median 10.5 years) outcomes in children presenting with traumatic brain injury and an initial Glasgow Coma Scale score of 3 or 4.

OBJECT: Patients with traumatic brain injury (TBI) with low presenting Glasgow Coma Scale (GCS) scores have very high morbidity and mortality rates. Neurosurgeons may be faced with difficult decisions in managing the most severely injured (GCS scores of 3 or 4) patients. The situation may be considered hopeless, with little chance of a functional recovery. Long-term data are limited regarding the clinical outcome of children with severe head injury. The authors evaluate predictor variables and the clinical outcomes at discharge, 1 year, and long term (median 10.5 years) in a cohort of children with TBI presenting with postresuscitation GCS scores of 3 and 4. METHODS: A review of a prospectively collected trauma database was performed. Patients treated at Riley Hospital for Children (Indianapolis, Indiana) from 1988 to 2004 were reviewed. All children with initial GCS (modified for pediatric patients) scores of 3 or 4 were identified. Patients with a GCS score of 3 were compared with those with a GCS score of 4. The outcomes of all patients at the time of death or discharge and at 1-year and long-term follow-up were measured with a modified Glasgow Outcome Scale (GOS) that included a "normal" outcome. Long-term outcomes were evaluated by contacting surviving patients. Statistical "classification trees" were formed for survival and outcome, based on predictor variables. RESULTS: Sixty-seven patients with a GCS score of 3 or 4 were identified in a database of 1636 patients (4.1%). Three of the presenting factors differed between the GCS 3 patients (n = 44) and the GCS 4 patients (n = 23): presence of hypoxia, single seizure, and open basilar cisterns on CT scan. The clinical outcomes were statistically similar between the 2 groups. In total, 48 (71.6%) of 67 patients died, remained vegetative, or were severely disabled by 1 year. Eight patients (11.9%) were normal at 1 year. Ten of the 22 patients with long-term follow-up were either normal or had a GOS score of 5. Multiple clinical, historical, and radiological factors were analyzed for correlation with survival and clinical outcome. Classification trees were formed to stratify predictive factors. The pupillary response was the factor most predictive of both survival and outcome. Other factors that either positively or negatively correlated with survival included hypothermia, mechanism of injury (abuse), hypotension, major concurrent symptoms, and midline shift on CT scan. Other factors that either positively or negatively predicted long-term outcome included hypothermia, mechanism of injury, and the assessment of the fontanelle. CONCLUSIONS: In this cohort of 67 TBI patients with a presenting GCS score of 3 or 4, 56.6% died within 1 year. However, approximately 15% of patients had a good outcome at 10 or more years. Factors that correlated with survival and outcome included the pupillary response, hypothermia, and mechanism. The authors discuss factors that may help surgeons make critical decisions regarding their most serious pediatric trauma patients.
