Tuberculous mastoiditis - a case series.

SUMMARY: Tuberculous mastoiditis (TBM) is a rare form of extrapulmonary tuberculosis (TB), which may result in catastrophic complications, including mastoid and ossicle destruction, hearing loss and intracranial spread if untreated. Diagnosis is challenging due to the paucibacillary nature of extrapulmonary TB, compounded by limited theatre access for specimen retrieval, resulting in delayed diagnosis and treatment initiation. In this case series, we discuss three cases of TBM (one paediatric and two adults) who presented to the public and private healthcare sectors in the Eastern Cape in 2022, underscoring that TB does not respect socioeconomic status.

Spatial Release From Masking With Bilateral Bone Conduction Stimulation at Mastoid for Normal Hearing Subjects.

This study investigates the effect of spatial release from masking (SRM) in bilateral bone conduction (BC) stimulation at the mastoid. Nine adults with normal hearing were tested to determine SRM based on speech recognition thresholds (SRTs) in simulated spatial configurations ranging from 0 to 180 degrees. These configurations were based on nonindividualized head-related transfer functions. The participants were subjected to sound stimulation through either air conduction (AC) via headphones or BC. The results indicated that both the angular separation between the target and the masker, and the modality of sound stimulation, significantly influenced speech recognition performance. As the angular separation between the target and the masker increased up to 150°, both BC and AC SRTs decreased, indicating improved performance. However, performance slightly deteriorated when the angular separation exceeded 150°. For spatial separations less than 75°, BC stimulation provided greater spatial benefits than AC, although this difference was not statistically significant. For separations greater than 75°, AC stimulation offered significantly more spatial benefits than BC. When speech and noise originated from the same side of the head, the "better ear effect" did not significantly contribute to SRM. However, when speech and noise were located on opposite sides of the head, this effect became dominant in SRM.

Comparison of the 3D-Exoscope and Operating Microscope in Mastoidectomy.

OBJECTIVES: The operating microscope (OM) commonly used in ear surgeries has several disadvantages, including a low depth of field, a narrow field of view, and unfavorable ergonomic characteristics. The exoscope (EX) was developed to overcome these disadvantages. Herein, we compared OM and EX during mastoidectomy and found out the feasibility of the EX. STUDY DESIGN: Prospective randomized comparative study. SETTING: Tertiary academic medical center. PATIENTS: Patients who had mastoidectomy for chronic otitis media with or without cholesteatoma between January 2022 and April 2022. INTERVENTION: Canal wall-up mastoidectomy (CWUM) or canal wall-down mastoidectomy (CWDM) using OM or EX without endoscope. MAIN OUTCOME MEASURES: Operative setting time (the time between the end of general anesthesia and incision), operative time (from incision to suture), postoperative audiologic outcomes, perioperative complications, and the decision to switch from EX to OM. RESULTS: Of 24 patients who were diagnosed with chronic otitis media or cholesteatoma, 12 each were randomly assigned to the OM or EX group. The mean operation time was 175 ± 26.5 minutes and 172 ± 34.6 minutes in the EX and OM group, respectively, which was not significantly different ( p = 0.843). The procedures in the EX group were successfully completed using a three-dimensional (3D)-EX without conversion to OM. All surgeries were completed without any complications. The postoperative difference in the air and bone conduction was 11.2 and 12.4 dB in the EX and OM groups, respectively, which was not significantly different ( p = 0.551). CONCLUSIONS: EX is comparable to OM in terms of surgical time, complications, and audiologic outcomes following mastoidectomy. The EX system is a potential alternative to OM. However, further improvements are required to overcome some drawbacks (deterioration of image resolution at high magnification, requirement of an additional controller for refocusing).

Diagnostic and Imaging Findings in Inflammatory Opacifications of the Middle Ear: A Review of the Literature.

Opacification in the middle ear and mastoid region can stem from a wide range of factors. In terms of diagnostic imaging, CT is the primary tool due to its exceptional spatial resolution, particularly for examining the temporal bone and ossicles. MRI complements this by offering detailed soft tissue lesion characterization and assessing involvement in the inner ear and cranial nerves. This study focuses on inflammatory causes of opacification in the middle ear and mastoid, with an emphasis on the utility of CT and MRI. This comprehensive review aimed to provide a practical framework for considering potential differential diagnoses.

The Role of Lumbar Drains in the Perioperative Management of Primary Spontaneous Temporal Lobe Encephaloceles and Cerebrospinal Fluid Leaks.

OBJECTIVE: To examine the role of lumbar drains (LDs) in the success of spontaneous temporal cerebrospinal fluid (CSF) leak and encephalocele repair. STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary academic health system. PATIENTS: Patients undergoing repair of spontaneous temporal lobe encephaloceles or middle fossa CSF leaks during years 2017 to 2023. INTERVENTIONS: Transmastoid, middle fossa craniotomy, or combination approaches to CSF leak repair. OUTCOME MEASURES: Failure rate, complication rate, length of stay (LOS), readmission. RESULTS: Sixty-nine patients were included, with a combination approach performed in 78.3%, transmastoid in 17.4%, and isolated middle fossa craniotomy in 4.3%. Mean body mass index was 33.2, mean bony defect size width was 6.51 mm, and defect locations included the epitympanum, antrum, mastoid, and petrous apex. Multilayer closure with three or more layers was performed in 87.0%. LD was used in 73.9% of cases for a mean duration 2.27 days and was associated with longer LOS (3.27 vs. 1.56 d, p = 0.006) but not with failure rate, complications, discharge destination, or readmission. Only one major complication occurred as a result of the drain, but low-pressure headache was anecdotally common. CONCLUSIONS: Use of LD in the repair of spontaneous CSF leaks and temporal lobe encephaloceles is associated with longer LOS but not failure rates or other admission-level outcomes.

Risk factors for recurrent acute mastoiditis in pediatric patients: a registry-based cohort study.

OBJECTIVE: To describe characteristics of pediatric patients with recurrent acute mastoiditis, and to identify risk factors for this condition. STUDY DESIGN: A retrospective cohort study. SETTING: Data based on electronic medical records of the largest Health Maintenance Organization in Israel. METHODS: Children hospitalized due to acute mastoiditis during the years 2008-2018 were identified, and their diagnosis was verified. Patients with recurrent acute mastoiditis were identified and grouped, and their characteristics were outlined and compared to those of the original group to identify risk factors for recurrence. RESULTS: During the 11-year period, a total of 1115 cases of children hospitalized due to acute mastoiditis were identified with a weighted incidence rate of 7.8/100,000. Of this group, 57 patients were diagnosed with recurrence following a full clinical recovery. The incidence proportion of recurrent acute mastoiditis was 5.1% (57/1115), male-to-female ratio was 27:30, 73.4% were younger than 24 months, the median period from the first episode was 3.4 months (IQR 2.0;10.0), and 82.5% of the patients (n = 47) had a single recurrence, whereas 18.5% (n = 10) had two recurrences or more. Mastoidectomy and swelling over the mastoid area during the first episode were identified as the main risk factors for recurrent mastoiditis HR = 4.7 [(2.7-8.2), p < 0.001] and HR = 2.55 [(1.4-4.8), p = 0.003], respectively. Mastoidectomy was the only independent significant risk factor for recurrence in a multivariate analysis. CONCLUSIONS: Mastoidectomy and swelling over the mastoid area during the first episode of acute mastoiditis were found strongly related independent risk factor for future recurrent episodes of acute mastoiditis.

Experiences of Percutaneous Endoscopic Approach for the Mastoid Lesions: A Novel Minimally Invasive Ear Surgery.

OBJECTIVES: We developed a novel keyhole surgery, named "percutaneous endoscopic ear surgery" (PEES), with the aim of further reducing the invasiveness of otologic surgery. We reported the cases we encountered and retrospectively analyzed the invasiveness of PEES. METHODS: We analyzed the ears of eight patients who underwent PEES for mastoid lesions that could not be manipulated with transcanal endoscopic ear surgery (TEES) at our hospital between July 2021 and November 2022. We performed PEES alone in three patients, including one case of type A (preauricular incision) and two cases of type B (retroauricular incision). The last five patients underwent combined endoscopic ear surgery, which is simultaneous PEES and TEES. In these cases, one patient underwent type A PEES, and four patients underwent type B PEES. RESULTS: PEES was performed in all patients without converting to conventional microscopic mastoidectomy. The mean length of skin incisions was 19.1 ± 4.5 mm, which was smaller than that in conventional mastoidectomy. In all cases, the average length of the major axis of the keyhole was <10 mm, indicating that sufficient minimally invasive surgery was achieved. The average depth from the keyhole to the deepest site was 21.6 ± 8.9 mm. There was no change in the mean hearing level before and after the surgery. CONCLUSION: PEES is a minimally invasive procedure for manipulating lesions in the mastoid. In addition, the combination of PEES and TEES is an ideal, minimally invasive procedure that can be used to treat all regions of the temporal bone.

150 years ago: Schwartze's 1873 mastoidectomy and its implementation over the following 2 years.

BACKGROUND: In 1873, Hermann Schwartze and Adolf Eysell described a new surgical technique for treating mastoid disease using a mallet, chisels, and gouges of various sizes instead of trephines or drill instruments also called "modern mastoidectomy." On the 150th jubilee of this landmark article, we pay tribute by studying the reception and implementation of mastoidectomy in the 2 years following its publication. METHODS: The commentaries published in the otological and medical literature between the second part of 1873 to the end of 1875 were studied with an emphasis on the three specialized otological journals and the otological textbooks that existed during this period. RESULTS AND CONCLUSION: The princeps paper Ueber die künstliche Eröffnung des Warzenfortsatzes ("On the artificial opening of the mastoid process") by Hermann Schwartze and Adolf Eysell published in 1873 was rapidly disseminated in the medical literature for nearly 1 year, and then entered a phase of evaluation followed by a phase of extension and implementation, before finding its definitive place in the history of mastoid process surgery.

A Novel Technique of Reduction Meatoplasty for Correction of Very Large Meatus from a Previous Canal Wall-Down Mastoidectomy.

OBJECTIVE: To evaluate the efficacy of reduction meatoplasty, a novel technique aiming to improve the usage of molded hearing aids and ear plugs in patients undergoing mastoid obliteration of a previous canal wall-down (CWD) mastoidectomy, complicated with a very large meatus. PATIENTS: Twenty-six patients from a tertiary care neurotology clinic with a very large meatus from a previous CWD mastoidectomy, who were unable to use molded hearing aids or ear plugs for water protection. INTERVENTION: Reduction meatoplasty after mastoid obliteration (cartilage strips and bone pate) of the CWD mastoidectomy. The procedure involves removing a wedge of skin and underlying soft tissue superiorly in the meatus. MAIN OUTCOME MEASURES: Reduction in meatus size, enabling usage of hearing aids and ear plugs. RESULTS: Twenty-six patients underwent mastoid obliteration and reduction meatoplasty to reduce meatus size. Patients were followed up for an average of 22 months postoperation. After operation, the meatus size was significantly reduced in all patients, enabling usage of over-the-counter ear plugs. In addition, all six patients with hearing aids could use standard occlusive hearing aid domes without requiring molded hearing aids. No patients showed symptoms of chronic infection in the mastoid cavity during the follow-up period. CONCLUSIONS: Results of reduction meatoplasty showed significant improvements in functionality of the external auditory meatus, indicating that this technique is effective in reducing meatus size and improving the normal meatal anatomy after mastoid obliteration.

Surgical Treatment for Troublesome Mastoid Cavities: Canal Wall Reconstruction With Bony Obliteration Versus Subtotal Petrosectomy.

INTRODUCTION: A chronically discharging modified radical mastoid cavity may require surgical intervention. We aim to explore two techniques. OBJECTIVE: To compare outcomes of subtotal petrosectomy (STP) and canal wall reconstruction with bony obliteration technique (CWR-BOT). STUDY DESIGN: Retrospective cohort study. SETTING: A tertiary referral center. PATIENTS: All patients with a chronically discharging mastoid cavity surgically treated at the Radboud University Medical Center by STP or CWR-BOT in 2015 to 2020, excluding patients with preoperative cholesteatoma. MAIN OUTCOME MEASURES: Dry ear rate, audiometry, and rehabilitation. SECONDARY OUTCOME MEASURES: Healing time, number of postoperative visits, complications, cholesteatoma, and need for revision surgeries. RESULTS: Thirty-four (58%) patients underwent STP, and 25 (42%) CWR-BOT. A dry ear was established in 100% of patients (STP) and 87% (CWR-BOT). The air-bone gap (ABG) increased by 12 dB in STP, and decreased by 11 dB in CWR-BOT. Postoperative ABG of CWR-BOT patients was better when preoperative computed tomography imaging showed aerated middle ear aeration. ABG improvement was higher when ossicular chain reconstruction took place. Mean follow-up time was 32.5 months (STP) versus 40.5 months (CWR-BOT). Healing time was 1.2 months (STP) versus 4.1 months (CWR-BOT). The number of postoperative visits was 2.5 (STP) versus 5 (CWR-BOT). Cholesteatoma was found in 15% (STP) versus 4% (CWR-BOT) of patients. Complication rate was 18% (STP) and 24% (CWR-BOT) with a need for revision in 21% (STP) and 8% (CWR-BOT), including revisions for cholesteatoma. CONCLUSION: STP and CWR-BOT are excellent treatment options for obtaining a dry ear in patients with a chronically discharging mastoid cavity. This article outlines essential contributing factors in counseling patients when opting for one or the other. Magnetic resonance imaging with diffusion-weighted imaging follow-up should be conducted at 3 and 5 years postoperatively.

Evaluation of inner ear damage by mastoid drilling with measurement of serum prestin (SLC26A5) levels.

OBJECTIVE: The objective of this study is to demonstrate any inner ear injury caused by drilling in mastoid surgery with prestin, outer hair cell motor protein specific to the cochlea. METHODS: The patients with chronic otitis media requiring mastoidectomy (n = 21) and myringoplasty (n = 21) were included. Serum prestin level obtained from blood samples was measured before surgery and on postoperative days 0, 3, and 7 using Human Prestin (SLC26A5) ELISA Kit. All patients underwent the Pure Tone Audiometry (PTA) test before surgery and on the postoperative 7th day. The drilling time was also recorded for all patients who underwent mastoidectomy. RESULTS: In both mastoidectomy and myringoplasty groups, the postoperative serum prestin levels increased on days 0 and 7 (pday-0 = 0.002, pday-7 = 0.001 and pday-0 = 0.005, pday-7 = 0.001, respectively). There was no significant difference in the serum prestin levels between the two groups, postoperatively. The PTA thresholds at day 7 did not change in either group. A significant decline at 2000 Hz of bone conduction hearing threshold in both groups and a decline at 4000 Hz in the myringoplasty group were found. There was no correlation between the drilling time and the increase of prestin levels in the postoperative day 0, 3, and 7. CONCLUSION: Our results showed that mastoid drilling is not related to a significant inner ear injury. Although the myringoplasty group was not exposed to drill trauma, there was a similar increase in serum prestin levels as the mastoidectomy group. Also, a significant decline at 2000 Hz of bone conduction hearing threshold in both groups and a decline at 4000 Hz in the myringoplasty group were found. These findings suggest that suction and ossicular manipulation trauma can lead to an increase in serum prestin levels and postoperative temporary or permanent SNHL at 2000 and 4000 Hz. LEVEL OF EVIDENCE: Level-4.

Trans-mastoid plugging of superior semicircular canal dehiscence: long-term follow-up.

OBJECTIVE: To evaluate the long-term outcomes of trans-mastoid plugging of superior semicircular canal dehiscence (SSCD), focusing on complicated cases. METHODS: In this cohort study, we included all patients who underwent trans-mastoid plugging of SSCD between 2009 and 2019. We evaluated the symptoms (autophony, sound-/pressure-induced vertigo, disequilibrium, aural fullness and pulsatile tinnitus) before and 1 year after surgery in the medical records. We systematically assessed the current symptoms 6.2 ± 3 years postoperative (range 2.2-12.3 years) using questionnaires sent by post and validated by telephone interviews. We also documented any complications and the need for further procedures. We compared pure tone and speech audiometry before and 1 year after surgery. Finally, the degree of mastoid pneumatisation and mastoid tegmen anatomy were reviewed on preoperative CT scans. RESULTS: We included 24 ears in 23 patients. No complications were recorded, and none required a second procedure for SSCD. Following surgery, oscillopsia and Tullio phenomena resolved in all patients. Hyperacusis, autophony, and aural fullness were also settled in all patients except one. Balance impairment persisted to some degree in 35% of patients. No deterioration over the years was reported regarding the above symptoms. On average, bone conduction pure tone average pre- and 1 year postoperative were 13.7 ± 17 and 20.5 ± 18 dB, respectively (P = 0.002). Air bone gaps were reduced from 12.7 ± 8 to 5.9 ± 6 (P = 0.001). Two patients had a significant sclerotic mastoid, three had a prominent low-lying mastoid tegmen, and two had both. Anatomy had no effect on outcome. CONCLUSION: Trans-mastoid plugging of SSCD is a reliable and effective technique which achieves long-lasting symptom control, even in cases with sclerotic mastoid or low-lying mastoid tegmen.

Association of the superior semicircular canal and tegmen tympani dehiscences and its relationship with the pneumatisation of the temporal bone.

PURPOSE: To analyse the degree of pneumatisation of the temporal bone when there is an association between dehiscence of the superior semicircular canal and dehiscence of the tegmen tympani. MATERIALS AND METHODS: We analysed a retrospective CT study of 124 selected cases. A single inclusion criterion was applied: the presence of a dehiscence of the tegmen tympani. On the other hand, the degree of temporal pneumatisation was assessed by axial and coronal planes, and has been divided into the following grades O, I, II and III, according to the status and relationship of the mastoid, the bony labyrinth, the petrous segment of the carotid canal and sigmoid sinus. RESULTS: Of the 124 cases studied, 35 (28.2%) presented both dehiscences. In 26 of the 35 (47.3%), grade II pneumatisation, 4 (14,8%), grade I, and 5 (11,9%) grade III was observed, with a statistically significant relationship (p < 0.001). On the other hand, we did not find a significant relationship when relating both dehiscences in any age or sex group. However, when relating the degree of pneumatisation to sex, among those with grade III pneumatisation, the proportion of men (52.4%) was significantly higher than that of women (47.6%) (p = 0.017). CONCLUSION: We have detected a statistically significant relationship between the coexistence of grade II pneumatisation and the presence of both dehiscences in the temporal bone.

Sex Estimation From Measurements of the Mastoid Triangle and Volume of the Mastoid Air Cell System Using Classical and Machine Learning Methods: A Comparative Analysis.

ABSTRACT: Previous studies on the sexual dimorphism of the mastoid triangle have typically focused on linear and area measurements. No studies in the literature have used mastoid air cell system volume measurements for direct anthropological or forensic sex determination. The aims of this study were to investigate the applicability of mastoid air cell system volume measurements and mastoid triangle measurements separately and combined for sex estimation, and to determine the accuracy of sex estimation rates using machine learning algorithms and discriminant function analysis of these data. On 200 computed tomography images, the distances constituting the edges of the mastoid triangle were measured, and the area was calculated using these measurements. A region-growing algorithm was used to determine the volume of the mastoid air cell system. The univariate sex determination accuracy was calculated for all parameters. Stepwise discriminant function analysis was performed for sex estimation. Multiple machine learning methods have also been used. All measurements of the mastoid triangle and volumes of the mastoid air cell system were higher in males than in females. The accurate sex estimation rate was determined to be 79.5% using stepwise discriminant function analysis and 88.5% using machine learning methods.

Quantification of Mastoid Air Cells and Opacification of the Middle Ear in Primary Ciliary Dyskinesia.

OBJECTIVE: To evaluate pneumatization and opacification of the temporal bone on computed tomography (CT) images in patients with primary ciliary dyskinesia (PCD). STUDY DESIGN: Retrospective case-control study. SETTING: Tertiary referral center. PATIENTS: Fifteen patients with PCD (30 ears) and 45 age-matched individuals without PCD (90 ears) as controls. INTERVENTION: Diagnostic only. MAIN OUTCOME MEASURES: Quantification of mastoid air cells in the PCD and control groups and comparison between them. Degree of middle ear opacification on CT images of the temporal bone in the PCD group. RESULTS: The volume of the mastoid air cells was 30% smaller in the PCD group than in the control group ( p < 0.05). The suppression ratio, which is defined to indicate how much the average volume of mastoid air cells in the PCD group is suppressed relative to the control group, was 64% lower in the PCD group ( p < 0.05). Opacification was noted in 47% of the mastoid air cells and 63% of the tympanic cavity on CT images of the temporal bone in the PCD group, which were significantly higher frequencies than in the control group (1.1% and 1.1%, respectively). CONCLUSIONS: Compared with individuals without PCD, those with PCD showed a significantly smaller volume of mastoid air cells and a significantly higher frequency of opacification of mastoid air cells and tympanic cavity on temporal bone CT. Otitis media raises suspicion for PCD, and the otological manifestations of PCD reported here could help to narrow the differential diagnosis and facilitate early treatment.

The Mastoid Crevasse and 3-Dimensional Considerations in Deep Plane Neck Lifting.

BACKGROUND: Advances in face and neck lifting involve release of tethering points along the superficial musculoaponeurotic system-platysma complex to freely manipulate the deep natural glide plane in the face and neck. OBJECTIVES: The aim of this article was to determine a combination of deep plane techniques for addressing the face and neck and to elucidate, for the first time, a measurable endpoint for the gonial angle. Analysis of deep plane tethering and decussation zones was also undertaken. METHODS: Extended deep plane surgery performed in 79 patients (158 hemifaces; age, 30-75 years; 95% female), over a 3-month period, was reviewed. Patients were followed for 1 year. Measurements were performed systematically during deep plane face and neck lifting. RESULTS: Before intervention, the mean [standard deviation] gonial depth was 9.4 [3.6] mm on the left and 8.3 [2.7] mm on the right. The mean depth created below the gonial angle when measuring the traditional suspension to the anterior mastoid was 15.8 [3.3] mm on the left and 13.7 [2.5] mm on the right. The distance postoperatively when measuring the gonial depth after performing the crevasse technique was 23.2 [2.2] mm on the left and 22.5 [2.5] mm on the right. This represents a mean increase in the advancement of 7.4 mm on the left and 8.8 mm on the right (average, 8.1 mm) which was demonstrated to be statistically significant bilaterally (P < .0001). CONCLUSIONS: The deep plane techniques described here aid manipulation of the deep plane and deep neck space, while also providing measurable endpoints and more effective modes of fixation by utilizing the mastoid crevasse. The use of techniques that release tension and allow redrape produce the most natural and well-balanced results.

Comparison between classic 'Fisch' and 'corner-tag' meatoplasty techniques after canal wall down tympanomastoidectomy.

PURPOSE: To compare outcomes of two different methods of meatoplasty following Canal Wall-Down tympanomastoidectomy. METHODS: A retrospective case review study of 48 patients with non-complicated unsafe chronic suppurative otitis media candidate for post-auricular canal wall-down tympanomastoidectomy via a post-auricular approach at Otolaryngology department, Benha university hospitals from January 2021 to January 2023, all were operated for the first time, and divided into 2 groups each of 24 patients. Group A submitted for classic 'Fisch', and group B 'Corner-Tag' meatoplasty. RESULTS: The mean age was 28.88 ± 13.26 years in group A and 33.33 ± 16.04 years in group B. Only one patient (4.2 %) in each group developed wound infection and none in both groups developed perichondritis. Two patients (8.3 %) in group B compared to only one patient (4.2 %) in group A had granulations on the meatal incision. One patient (4.2 % of group A) needed revision meatoplasty. Group B needed more time for epithelization (mean 7.33 ± 0.96 weeks) than group A (mean 6.5 ± 0.88 weeks; P = 0.003*) also resulted in wider mean new meatus in group B (mean 10.50 ± 1.02 mm) than in group A (mean 9.63 ± 1.41 mm; P = 0.02*). CONCLUSION: Both techniques had comparable post-operative complications. 'Corner-Tag' technique needed more time for healing and epithelization but gave a wider new meatal diameter than 'Fisch' meatoplasty after one year of follow-up.

Intratemporal facial nerve neurofibroma causing facial paralysis in an infant: Case report and review of the literature.

This article describes the first recorded case of intratemporal neurofibroma in an infant. A literature review of all other existing cases of intratemporal neurofibroma is performed, finding that the majority of cases involve multiple segments and can be found in the mastoid segment most often. Most common symptoms described included facial paralysis, otalgia, and conductive hearing loss, respectively.
