Otologic opioid usage and pain control in the postoperative period: An observational prospective study.

PURPOSE: Evaluate opioid prescribing patterns, opioid consumption, and patient pain patterns following otologic surgery. MATERIALS AND METHODS: Patients were included if they were ≥18 years old and received otologic surgery between November 2019 and August 2020. Patients were provided a survey which included a visual analog scale for recording their pain postoperatively and the amount of opioid they had remaining. Patients who did not complete all portions of the survey were excluded. RESULTS: Ninety-one patients completed the post-operative questionnaire. Collectively, patients were prescribed 5797 morphine milligram equivalents and used 3092: approximately 47% went unused. Of patients receiving a transcanal incision (n = 28/91, 31%), 70% went unused, whereas patients receiving a postauricular incision (n = 57/91, 63%), 38% went unutilized. The utilization difference between transcanal and postauricular cohorts was significant (p = 0.002). On multivariate analysis, patients who received a postauricular incision had 60% more opioid usage (p < 0.001), whereas those with a transcanal incision had an average reduction of 40% in opioid usage (p < 0.001). CONCLUSIONS: A significant amount of opioid medication went unused in this study. Patients with postauricular incisions had significantly increased opioid utilization as compared to those with transcanal incisions. Otologists may be able to successfully manage pain in the postoperative period with a reduced opioid prescription multimodal analgesia and increased patient education. Further study is needed to support this suggestion.

3D printed temporal bone as a tool for otologic surgery simulation.

PURPOSE: In this face validity study, we discuss the fabrication and utility of an affordable, computed tomography (CT)-based, anatomy-accurate, 3-dimensional (3D) printed temporal bone models for junior otolaryngology resident training. MATERIALS AND METHODS: After IRB exemption, patient CT scans were anonymized and downloaded as Digital Imaging and Communications in Medicine (DICOM) files to prepare for conversion. These files were converted to stereolithography format for 3D printing. Important soft tissue structures were identified and labeled to be printed in a separate color than bone. Models were printed using a desktop 3D printer (Ultimaker 3 Extended, Ultimaker BV, Netherlands) and polylactic acid (PLA) filament. 10 junior residents with no previous drilling experience participated in the study. Each resident was asked to drill a simple mastoidectomy on both a cadaveric and 3D printed temporal bone. Following their experience, they were asked to complete a Likert questionnaire. RESULTS: The final result was an anatomically accurate (XYZ accuracy = 12.5, 12.5, 5 µm) 3D model of a temporal bone that was deemed to be appropriate in tactile feedback using the surgical drill. The total cost of the material required to fabricate the model was approximately $1.50. Participants found the 3D models overall to be similar to cadaveric temporal bones, particularly in overall value and safety. CONCLUSIONS: 3D printed temporal bone models can be used as an affordable and inexhaustible alternative, or supplement, to traditional cadaveric surgical simulation.

Rate of tympanic membrane perforation after intratympanic steroid injection.

PURPOSE: To determine the rate of persistent tympanic membrane perforation after intratympanic steroid injection. To determine which comorbid conditions and risk factors are associated with prolonged time to perforation closure following intratympanic steroid injection. MATERIALS AND METHODS: Clinical data were gathered for patients who had undergone intratympanic steroid injection to treat sudden sensorineural hearing loss or Ménière's disease. Primary outcomes analysis included rate of persistent tympanic membrane perforation, defined as perforation at least 90days following last injection, and time to perforation healing. Age, sex, number of injections, smoking status, diabetes mellitus, previous head and neck irradiation, and concurrent oral steroids, were analyzed as potential predictors of persistent perforation. RESULTS: One hundred ninety two patients were included in this study. Three patients (1.6%) had persistent tympanic membrane perforations. All three patients received multiple injections. One patient underwent tympanoplasty for repair of persistent perforation. The median time to perforation healing was 18days. There was no statistically significant variable associated with time to perforation healing. However, patients with prior history of head and neck radiation averaged 36.5days for perforation healing compared to 17.5days with no prior history of radiation and this approached statistical significance (p=0.078). CONCLUSIONS: The rate of persistent tympanic membrane perforation following intratympanic steroid injection is low. Patients with a history of radiation to the head and neck may be at increased risk for prolonged time for closure of perforation.

Evaluation of Subjective Tinnitus Severity and Distortion Product Otoacoustic Emissions and Extended High-Frequency Audiometry.

OBJECTIVE: Tinnitus is a multifactorial phenomenon with quality-of-life detriments for those affected by it. We aim to establish a relationship between subjective tinnitus severity with objective audiometric data in the extended high frequency (EHF) from 9 to 16 khz and with distortion product otoacoustic emissions (DPOAE). We hypothesize that severe subjective tinnitus as measured by the Tinnitus Handicap Inventory (THI) does not correlate with increased hearing thresholds in the EHF range. STUDY DESIGN: Prospective. SETTING: Single Tertiary Care Center. METHODS: Patients identified with tinnitus and normal hearing thresholds within standard frequency range (250-8000 Hz) were consented for participation. Those with underlying otologic disease, trauma, radiotherapy, or ototoxic drug use were excluded. The THI questionnaire was given to eligible patients and audiometric test results were collected. THI scores were categorized by severity groups. An n = 20 to 30 was determined to have an effect size of 0.7 with a significance level of P = .05. RESULTS: THI and audiometric data were collected for 38 patients and categorized into mild (n = 18, 47.4%), moderate (n = 8, 21.1%), slight (n = 7, 18.4%), and severe (n = 5, 13.2%) tinnitus severity groups. Mean THI score was 32.3 ± 19.6 with a statistically significant difference in scores by assigned THI severity group (P < .01). There were no significant differences or linear relationship among hearing thresholds in EHF range or DPOAE stratified by subjective tinnitus group (P = .49, r2 = 0.10) CONCLUSION: Subjective tinnitus severity is not predictive of audiometric outcomes. This finding can be used as a counseling tool to help tinnitus patients manage symptoms, expectations, and overall treatment outcomes.

Cognitive and language outcomes for pediatric hearing loss with otologic surgery.

OBJECTIVES: To test the hypothesis that surgical otologic intervention for any type of pediatric hearing loss decreases the odds for incident adverse cognitive and linguistic developmental outcomes. STUDY DESIGN: Retrospective cohort database study. METHODS: Electronic medical record data from the TriNetX Research Network were queried for children with congenital, sensorineural, conductive, and mixed hearing loss (HL) between ages 0 and 5 years. Patients were further stratified by presence (HL + surgery) or absence (HL-surgery) of surgical intervention at any point following diagnosis, including cochlear implantation, tympanoplasty with or without mastoidectomy, and tympanostomy. Primary outcomes were defined as odds for new adverse cognitive or linguistic outcomes at any point given HL treatment status [odds ratio with 95% confidence interval, (OR; 95%CI, p-value)]. Cohorts were balanced using propensity-score matching (PSM) based on US census-defined demographics and clinically relevant congenital conditions. RESULTS: Of 457,636 total patients included in the study, 118,576 underwent surgery (HL + surgery cohort) and 339,060 did not (HL-surgery). In matched cohorts, surgical otologic intervention significantly decreased the odds of developing cognitive disorders including scholastic, motor, psychological developmental disorders, and pervasive developmental delays (p < 0.01). CONCLUSIONS: Surgical interventions for treatment of pediatric HL including cochlear implantation, tympanoplasty with or without mastoidectomy, and tympanostomy should be considered as they may prevent delays in development.

Multimodal Analgesia and Patient Education Reduce Postoperative Opioid Consumption in Otology.

OBJECTIVE: This study sought to validate alternative pain management strategies that can reduce reliance on opioids for postoperative pain management in otology. STUDY DESIGN: Prospective cohort study. SETTING: Single tertiary-care facility. METHODS: Adult patients who underwent outpatient otologic surgery from September 2021 to July 2022 were randomized into treatment cohorts. The opioid monotherapy cohort received a standard opioid prescription. The multimodal analgesia cohort received the same opioid prescription, prescriptions for acetaminophen and naproxen, and additional pain management education with a flyer on discharge. All patients completed a questionnaire 1 week after surgery to evaluate opioid usage and pain scores. RESULTS: Eighty-six patients completed the study. The opioid monotherapy cohort (n = 42) and multimodal analgesia cohort (n = 44) were prescribed an average of 42.1 ± 20.4 morphine milligram equivalents (MME) and 38.4 ± 5.7 MME, respectively (p = 0.373). Four patients (9.52%) in the opioid monotherapy cohort required opioid refills compared to 1 patient (2.27%) in the multimodal analgesia cohort (p = 0.156). Multivariate analysis demonstrated that the multimodal analgesia cohort consumed significantly fewer opioids on average than the opioid monotherapy cohort (11.9 ± 15.9 MME vs 22.8 ± 28.0 MME, respectively). There were no significant differences in postoperative rehospitalizations (p = 0.317) or Emergency Department visits (p = 0.150). Pain scores on the day of surgery, postoperative day (POD) 1, POD3, and POD7 were not significantly different between cohorts (p = 0.395, 0.896, 0.844, 0.765, respectively). CONCLUSION: The addition of patient education, acetaminophen, and naproxen to postoperative opioid prescriptions significantly reduced opioid consumption without affecting pain scores, refill rates, or complication rates after otologic surgery.

A Comparison of Outcomes Using Combined Intra- and Extradural versus Extradural-Only Repair of Tegmen Defects.

Objective Tegmen tympani or tegmen mastoideum defects involve dehiscence of the temporal bone that can be a source of cerebrospinal fluid (CSF) otorrhea. Herein, we compare a combined intra-/extradural repair strategy with an extradural-only repair as it pertains to surgical and clinical outcomes. Design A retrospective review from our institution was performed of patients with tegmen defects requiring surgical intervention. Participants Patients with tegmen defects who underwent surgery (combined transmastoid and middle fossa craniotomy) for repair of tegmen defects between 2010 and 2020 were inclined in this study. Results A total of 60 patients with 40 intra-/extradural (mean follow-up time: 1,060 ± 1,103 days) and 20 extradural-only (mean follow-up time: 519 ± 369 days) repairs were identified. No major differences in demographic factors or presenting symptoms were identified between the two cohorts. There was no difference in hospital length of stay between the two patient cohorts (mean: 4.15 vs. 4.35 days, p = 0.8). In the extradural-only repair technique, synthetic bone cement was more frequently used (100 vs. 7.5%, p < 0.01), whereas in the combined intra-/extradural repair, synthetic dural substitute was used more often (80 vs. 35%, p < 0.01), with similar successful surgical outcomes achieved. Despite disparities in the techniques and materials used for repair, there were no differences in complication rates (wound infection, seizures, and ossicular fixation), 30-day readmission rates, or persistent CSF leak between the two treatment cohorts. Conclusion The results of this study suggest no difference in clinical outcomes between combined intra-/extradural versus extradural-only repair of tegmen defects. A simplified extradural-only repair strategy can be effective, and may reduce the morbidity of intradural reconstruction (seizures, stroke, and intraparenchymal hemorrhage).

Association of Smoke and Nicotine Product Consumption With Sensorineural Hearing Loss: A Population-Level Analysis.

OBJECTIVE: To test the hypothesis that use of cigarettes or other products with either cigarette-like smoke profile or high nicotine content by young populations increases the odds of developing sensorineural hearing loss (SNHL). STUDY DESIGN: Retrospective cohort study. SETTING: TriNetX US Collaborative Network (2003-2022). PATIENTS: Approximately 3.6 million patients at least 18 years old. INTERVENTION: None. MAIN OUTCOME MEASURES: The primary outcome of interest was diagnosis of SNHL, defined using medical billing codes ( International Classification of Diseases, Tenth Revision , Current Procedural Terminology , etc.). Cohort inclusion criteria included electronic health record entry after 2003, age 18 to 54 or 55+ years at index, and status of cigarette, noncigarette nicotine, or cannabis use. Covariates were controlled via 1:1 propensity score matching for SNHL-related conditions, including diabetes mellitus and ischemic diseases. Odds for developing SNHL were calculated against control subjects aged 18 to 54 years who have no record of nicotine/cannabis use. RESULTS: Odds for developing SNHL are higher for people 18 to 54 years old who use any nicotine product (odds ratio [95% confidence interval], 5.91 [5.71-6.13]), cigarettes only (4.00 [3.69-4.33]), chewing tobacco only (9.04 [7.09-11.63]), or cannabis only (3.99 [3.60-4.44]) compared with control. People 55+ years old who use no products also showed increased odds for SNHL (4.73 [4.63-4.85]). CONCLUSIONS: Both nicotine and smoke exposure seem to be strongly associated with increased odds for developing SNHL, with chewing tobacco having the strongest association.

Surgical management of temporal meningoencephaloceles, cerebrospinal fluid leaks, and intracranial hypertension: treatment paradigm and outcomes.

OBJECT: Thinning of the tegmen tympani and mastoideum components of the temporal bone may predispose to the development of meningoencephaloceles and spontaneous CSF leaks. Surgical repair of these bony defects and associated meningoencephaloceles aids in the prevention of progression and meningitis. Intracranial hypertension may be a contributing factor to this disorder and must be fully evaluated and treated when present. The purpose of this study was to establish a treatment paradigm for tegmen defects and elucidate causative factors. METHODS: The authors conducted a retrospective review of 23 patients undergoing a combined mastoidectomy and middle cranial fossa craniotomy for the treatment of a tegmen defect. RESULTS: The average body mass index (BMI) among all patients was 33.2 ± 7.2 kg/m(2). Sixty-five percent of the patients (15 of 23) were obese (BMI > 30 kg/m(2)). Preoperative intracranial pressures (ICPs) averaged 21.8 ± 6.0 cm H(2)O, with 10 patients (43%) demonstrating an ICP > 20 cm H(2)O. Twenty-two patients (96%) had associated encephaloceles. Five patients underwent postoperative ventriculoperitoneal shunting. Twenty-two CSF leaks (96%) were successfully repaired at the first attempt (average follow-up 10.4 months). CONCLUSIONS: Among all etiologies for CSF leaks, those occurring spontaneously have the highest rate of recurrence. The surgical treatment of temporal bone defects, as well as the recognition and treatment of accompanying intracranial hypertension, provides the greatest success rate in preventing recurrence. After tegmen dehiscence repair, ventriculoperitoneal shunting should be considered for patients with any combination of the following high-risk factors for recurrence: spontaneous CSF leak not caused by another predisposing condition (that is, trauma, chronic infections, or prior surgery), high-volume leaks, CSF opening pressure > 20 cm H(2)O, BMI > 30 kg/m(2), preoperative imaging demonstrating additional cranial base cortical defects (that is, contralateral tegmen or anterior cranial base) and/or an empty sella turcica, and any history of an event that leads to inflammation of the arachnoid granulations and impairment of CSF absorption (that is, meningitis, intracranial hemorrhage, significant closed head injury, and so forth).

Adenomatous Neuroendocrine Tumors of the Middle Ear: A Multi-institutional Investigation of 32 Cases and Development of a Staging System.

OBJECTIVE: To date, less than 150 cases of middle ear adenomatous neuroendocrine tumors (MEANTs) have been reported in the English literature. The objective of this study was to provide a contemporary analysis of these rare lesions and develop a consensus-driven staging system. STUDY DESIGN: Multi-institutional retrospective histopathologic, radiologic, and clinical review. SETTING: Six tertiary referral centers. PATIENTS: Thirty-two patients with pathologically confirmed MEANT. INTERVENTION: Surgical resection, adjuvant therapy. MAIN OUTCOME MEASURES: Clinical manifestations, outcomes, staging system. RESULTS: Patients commonly presented with progressive conductive or mixed hearing loss (90%), aural fullness (50%), and tonal tinnitus (46%). Pulsatile tinnitus (16%), carcinoid syndrome (4%), and facial nerve paresis (4%) were less commonly observed. MEANTs frequently mimicked temporal bone paraganglioma (31%) and cholesteatoma (15%) at presentation. According to a novel T/N/M/S staging system (S = secretory tumor) proposed herein, there were 6 (19%) T1, 19 (59%) T2, and 7 (22%) T3 MEANTs. T3 tumors were significantly more likely to undergo subtotal or near total resection compared with lower staged tumors secondary to adherence to critical neurovascular structures such as the petrous internal carotid artery and facial nerve (p = 0.027). Patients with T3 MEANTs were more likely to experience multiple recurrences, require adjuvant therapy with a somatostatin analogue, or develop permanent facial nerve paresis compared with lower staged tumors. At last follow up, no patients with T1 MEANTs had developed recurrence, whereas 37% (7/19) of patients with T2 MEANT and 57% (4/7) of patients with T3 MEANT experienced either disease recurrence after gross total resection (GTR) or regrowth of known residual tumor requiring additional surgery at a median duration of 72 months (95% CI, 24-84). CONCLUSIONS: Patients with MEANTs can present with nonspecific symptomatology that overlaps with more commonly encountered middle ear lesions. MEANT exhibits a proclivity for recurrence according to T-stage and long-term clinical follow up is necessary, particularly for advanced stage tumors.

Retropharyngeal pseudomeningocele presenting as dysphagia after atlantooccipital dislocation.

EDUCATIONAL OBJECTIVE: At the conclusion of this paper, the readers should be able to recognize a retropharyngeal pseudomeningocele as a potential complication of atlanto occipital dislocation. OBJECTIVES: To demonstrate how a retropharyngeal pseudomeningocele may present as dysphagia in a patient who is recovering from atlanto occipital dislocation as well as to discuss the treatment options in this situation. STUDY DESIGN: Case report and literature review. METHODS: Analysis of a case through medical record and literature review. RESULTS: A retropharyngeal pseudomeningocele is a very rare complication of atlanto occipital dislocation. It may develop weeks after the initial injury and can present with respiratory or swallowing difficulties. Decompression via a ventriculoperitoneal or lumboperitoneal shunt facilitates resolution of the cerebral spinal fluid collection. CONCLUSIONS: A retropharyngeal pseudomeningocele should be considered in all patients status post-atlanto occipital dislocation who are experiencing respiratory distress or dysphagia.

Penetrating middle ear trauma: a report of 2 cases.

Penetrating middle ear injury can result in hearing loss, vertigo, and facial nerve injury. We describe the cases of 2 children with penetrating trauma to the right ear that resulted in ossicular chain disruption; one injury was caused by cotton-tipped swabs and the other by a wooden matchstick. Symptoms in both children included hearing loss and otalgia; in addition, one child experienced ataxia and the other vertigo. Physical examination in both cases revealed a perforation in the posterosuperior quadrant of the tympanic membrane and visible ossicles. Audiometry identified a moderate conductive hearing loss in one child and a mild sensorineural hearing loss in the other. Both children underwent middle ear exploration and reduction of a subluxed stapes. We discuss the diagnosis, causes, and management of penetrating middle ear trauma. To reduce the morbidity associated with these traumas, otologic surgeons should act promptly and be versatile in choosing methods of repairing ossicular chain injuries.

Intralabyrinthine schwannomas.

OBJECTIVE: To describe the patient presentation, radiographic findings, and treatment results in a series of eight patients with a diagnosis of intralabyrinthine schwannoma, and to review the presentation of other cases of intralabyrinthine schwannoma in the English otolaryngologic literature. METHODS: Retrospective review of patient records, operative reports, and radiologic studies, and review of the literature. RESULTS: Eight patients with a variety of otologic symptoms including progressive hearing loss, episodic vertigo, and tinnitus were found to have a schwannoma involving the vestibule or cochlea. Surgery was performed to remove the tumors from four patients with nonserviceable hearing. The patients experienced significant improvement in their vertigo and tinnitus after surgery. Observation and serial magnetic resonance imaging were adequate treatment of the four patients with serviceable hearing. In the literature review, 447 cases of intralabyrinthine schwannoma were identified, and the presentations were similar to those in the cases described here. CONCLUSION: Intralabyrinthine schwannomas are rare tumors that arise from the distal portion of either the vestibular nerve or the cochlear nerve. Consequently, the cochlea, the semicircular canals, the vestibule, or a combination of these structures may become involved with these lesions. Transmastoid labyrinthectomy or a transotic approach can be used to remove intralabyrinthine tumors from patients with nonserviceable hearing and severe vertigo or tinnitus. In addition, these surgical approaches should be used if the tumor grows to involve the internal auditory canal. Observation is an appropriate option for patients who have serviceable hearing.

Temporal bone hemangiomas involving the facial nerve.

OBJECTIVE: Hemangiomas of the facial nerve are rare tumors that can mimic more common temporal bone tumors such as vestibular schwannomas and facial nerve schwannomas. This article reviews the diagnostic challenges in the surgical treatment of facial nerve hemangiomas. STUDY DESIGN: Two case reports and literature review. RESULTS: Early diagnosis and surgical excision of facial nerve hemangiomas can sometimes allow tumor removal with facial nerve preservation. In patients in whom the facial nerve needs to be resected to remove the hemangioma, primary anastomosis or cable nerve grafting can yield House-Brackmann Grade III/VI postoperative facial nerve function. CONCLUSION: Complete surgical excision of facial nerve hemangiomas with primary facial nerve repair (when necessary) is the treatment of choice for these lesions.

Current results of the surgical management of acoustic neuroma.

A retrospective analysis of 162 consecutive cases in 160 patients who underwent microsurgical resection of vestibular schwannomas between October 1995 and June 2001 was undertaken to compare the results with those of other treatment modalities. Patient hospital records, operative video pictures, neuroimaging studies, audiograms, and follow-up data were reviewed. The mean follow-up period was 24 months.There were 34 small (<1.5 cm), 92 medium (1.5-3 cm), and 36 (>3 cm) large tumors. Six were recurrent tumors. Gross total resection was accomplished in all 34 small tumors and 92 medium tumors but only in 50% of the large tumors. Among the 126 small and medium tumors, the facial nerve was saved anatomically in 124 patients. On long-term follow up, facial function was preserved in 94.4% of all patients. Anatomically, the cochlear nerve was preserved in 55.9% of the small and 20.7% of the medium tumors. Function was preserved (Gardner-Robertson class 1 and 2) in 25% of the small and in 19.4% of the medium tumors. Cerebrospinal leakage was present in 10.5%, meningitis in 9.9%, wound infection in 3.7%, and hematoma or contusion in 2.5%. Only one patient died (mortality rate 0.6%). Our data reflect that surgical removal should be the standard management for acoustic tumors, particularly for large and medium tumors, and can be accomplished with acceptable complication rates.

Hepatocellular cancer metastatic to the zygoma: primary resection and immediate reconstruction.

Hepatocellular carcinoma is common worldwide but relatively rare in the United States, where only 13,000 new cases are diagnosed each year. Metastasis to osseous structures in the head and neck are extremely rare; when they do occur, most appear as oral cavity masses secondary to mandibular and maxillary involvement. We report the case of an isolated zygomatic metastasis in a patient who had been previously treated for hepatocellular carcinoma with orthotopic liver transplantation. The patient underwent a complete excision of the mass followed by immediate reconstruction of the zygomaxillary buttress and the orbital rim and floor. To our knowledge, only one other case similar to ours has been previously reported; in that instance, the metastatic tumor was not resectable.

Atypical presentation of geniculate ganglion venous malformation in a child: conductive hearing loss without facial weakness.

We describe an unusual presentation of geniculate ganglion venous malformation, a rare facial nerve lesion, emphasizing the importance of the differential diagnosis, imaging characteristics, and controversies in management. A child presented with moderate right-sided conductive hearing loss and a House-Brackmann grade I facial nerve function bilaterally. Computed tomography and magnetic resonance imaging showed a mass demonstrating features consistent with a geniculate ganglion venous malformation. To our knowledge, this is the first pediatric case of geniculate ganglion venous malformation presenting solely with conductive hearing loss. Proper management requires differentiating this condition from other geniculate and temporal bone lesions.

Bilateral skull base osteomyelitis in an immunocompetent patient.

A 75-year-old immunocompetent man presented to our office with right otalgia. After a comprehensive workup, he was found to have right temporal bone osteomyelitis and was treated with intravenous antibiotics. He then began to experience left-sided otalgia and was diagnosed with and treated for left temporal bone osteomyelitis. Subsequently, he began to exhibit myelopathic symptoms, and imaging revealed a C2 inflammatory process. The patient underwent endoscopic transoral odontoidectomy with resection of a large C1 to C2 pannus and recovered with no neurologic deficit. Skull base osteomyelitis is an uncommon condition that usually occurs in immunocompromised patients. Prompt diagnosis and appropriate treatment are of utmost importance in managing this condition.
