[Ab] Resumo:To investigate the effects of surgery type [intact canal wall (ICW) or canal wall down (CWD) mastoidectomy] and different ossiculoplasty materials on hearing outcome in single-staged cholesteatoma surgery. A retrospective case-control study. A total of 116 cases (97 adults, 29 children) underwent surgery, including ossiculoplasty, between 2012 and 2015 for cholesteatoma. Patients who had undergone surgery for the first time, and whose grafts were successful, were included in the study. Patients with adhesive otitis media, unsuccessful grafts, revision and recurrent cases, radical mastoidectomy, and craniofacial anomalies were excluded. Audiogram examinations of the enrolled patients were performed 3-6 months after surgery, and the audiometric results were analyzed according to the criteria of the American Academy of Otolaryngology, Head and Neck Surgery. All ossiculoplasties were performed during the first operation. The preoperative average air-bone gap (ABG) of the patients was decreased from 31.37 ± 10.1 to 27.42 ± 10.4 dB; this decrease was found to be highly significant (p = 0.0001). Concerning the ICW technique, statistical evaluation of the hearing gain at frequencies of 500, 1000, and 2000 Hz, as well as the mean frequency, showed a high level of significance. Improvement at 4000 Hz was not found to be statistically significant. When the ABGs at 500, 1000, 2000, and 4000 Hz, and the mean frequency in patients with an hydroxyapatite-partial ossicular replacement prosthesis (HA-PORP) or autograft-partial ossicular replacement prosthesis (APORP), were evaluated, it was found that, at 4000 Hz, the APORP significantly reduced the ABG (p = 0.02). No significant difference was determined between patients with the hydroxyapatite-total ossicular replacement prosthesis (HA-TORP) and those with the autograft-total ossicular replacement prosthesis (ATORP) (p = 0.565). Although the use of the malleus as an APORP was found to be less effective than other autografts, the degree of advantage of using the incus, malleus, cortical bone, and cartilage did not significantly differ between materials (p = 0.152). Despite the effects of the incus, malleus, and cortical bone not differing in terms of the postoperative ABG (p = 0.160), incus usage was highly beneficial for hearing gain (p = 0.009). Despite CWD tympanoplasty affecting all frequencies, it has a particularly negative effect on the hearing threshold at 1000 Hz. In patients with partial ossicular replacement, autogenous grafts are more successful in restoring hearing at high frequencies, particularly at 4000 Hz. Although autogenous materials do not differ in terms of partial replacement effectiveness, the incus has been shown to be most effective for total replacement.

[Ab] Resumo:OBJECTIVE: Acoustic evaluation of reconstruction of the lateral epitympanic wall with bone or cartilage in a temporal bone study, and evaluation of audiometric data of patients who underwent cholesteatoma surgery with reconstruction of the lateral epitympanic wall with horseshoe-shaped cartilage. STUDY DESIGN: Temporal bone study and retrospective chart review. METHODS: Preparation of temporal bones included reconstruction of the epitympanic wall with fixated and loose cartilage and bone. The volume velocities of the stapes footplate were measured from the inner-ear side of the footplate by laser scanning doppler vibrometry following sound stimulation in the outer ear canal. Additionally, the audiometric data of 13 consecutive patients who underwent epitympanic cholesteatoma surgery, with an intact ossicular chain and reconstruction of the scutum with a horseshoe-shaped cartilage in contact with the malleus' neck, were evaluated retrospectively. RESULTS: The experimental results showed similar volume velocities at the stapes footplate for the fixated and unfixated cartilage as well as for the unfixated bone. However, the fixated bone yielded significantly reduced volume velocities. Clinical data confirmed that the cartilaginous horseshoe- technique allowed for a stable reconstruction of the scutum with satisfying audiometric outcome. CONCLUSION: In case of cholesteatoma surgery and the need for the reconstruction of the scutum, no adverse effects on hearing outcome are to be expected by using the malleus' neck as an anchoring point for cartilaginous scutum reconstruction. LEVEL OF EVIDENCE: NA. Laryngoscope, 127:1427-1434, 2017.

[Ti] Título:Early development of the malleus and incus in humans.

[Ab] Resumo:It is widely accepted by developmental biologists that the malleus and incus of the mammalian middle ear are first pharyngeal arch derivatives, a contention based originally on classical embryology that has now been backed up by molecular evidence from rodent models. However, it has been claimed in several studies of human ossicular development that the manubrium of the malleus and long process of the incus are actually derived from the second arch. This 'dual-arch' interpretation is commonly presented in otolaryngology textbooks, and it has been used by clinicians to explain the aetiology of certain congenital abnormalities of the human middle ear. In order to re-examine the origins of the human malleus and incus, we made three-dimensional reconstructions of the pharyngeal region of human embryos from 7 to 28 mm crown-rump length, based on serial histological sections from the Boyd Collection. We considered the positions of the developing ossicles relative to the pharyngeal pouches and clefts, and the facial and chorda tympani nerves. Confirming observations from previous studies, the primary union between first pharyngeal pouch and first cleft found in our youngest specimens was later lost, the external meatus developing rostroventral to this position. The mesenchyme of the first and second arches in these early embryos seemed to be continuous, but the boundaries of the developing ossicles proved to be very hard to determine at this stage. When first distinguishable, the indications were that both the manubrium of the malleus and the long process of the incus were emerging within the first pharyngeal arch. We therefore conclude that the histological evidence, on balance, favours the 'classical' notion that the human malleus and incus are first-arch structures. The embryological basis of congenital ossicular abnormalities should be reconsidered in this light.

[Ab] Resumo:HYPOTHESIS: In the literature several surgical methods have been reported that aim to improve hearing in patients with isolated malleus fractures; however, it is still not clear which method gives the best results. BACKGROUND: In this study, laser Doppler vibrometry (LDV) was used to compare the outcome of different surgical methods on malleus fractures in fresh frozen human temporal bones. METHODS: Fractured malleus shafts of defrosted human temporal bones were repaired with bone cement, with a malleus prosthesis from cortical bone, or with a partial ossicular replacement prosthesis (PORP) from cortical bone, and LDV measurements were obtained for analysis. RESULTS: The best result was achieved with the bone cement only, applied directly at the site of the fracture. The malleus prosthesis and the PORP gave similar results. CONCLUSION: All three surgical methods gave good results, but when the distal end of the fractured malleus can be attached close to the proximal end, the technique using only cement tends to be the best option. If the parts are too far apart, a malleus prosthesis or a PORP would be good options.

[Ab] Resumo:OBJECTIVE: To evaluate the effectiveness of malleus to stapes bone cement rebridging (MS-BCR) for Austin Kartush group A ossicular defects and compare the audiological results with incus interposition (IP) and incus to stapes bone cement rebridging (IS-BCR). METHODS: Patients for whom type 2 tympanoplasty had been performed in a tertiary referral center were examined. Revision cases and those with graft failure were excluded. Three treatment groups were IS-BCR, IP, and MS-BCR. Preoperative and postoperative audiological results were compared. RESULTS: A total of 92 patients were enrolled. The IS-BCR was performed in 42 (45.65%), IP in 18 (19.56%), and MS-BCR in 32 (34.78%) patients. Postoperative mean air bone gap was 20.1 ± 9.8 dB HL and did not differ significantly between the groups (P = .271). Postoperative mean air bone gap less than 20 dB HL was achieved in 23 (54.7%) patients in IS-BCR, 10 (55.5%) patients in IP group, and 24 (75%) patients in MS-BCR group (P = .06). Mean closure in air bone gap was 14.0 ± 11.6 dB HL. The changes in mean and frequency-specific air bone gap were not significantly different between treatment groups (P > .05). CONCLUSION: Malleus to stapes bone cement rebridging may provide hearing results comparable to IS-BCR and IP.

[Ti] Título:The anterior process of the malleus in Cetartiodactyla.

[Ab] Resumo:The anterior fixation of the anterior process of the malleus has been studied in a number of Cetartiodactyla. This anterior process, also known as processus gracilis, is provided by the prearticular (gonial), a dermal bone, whereas the cartilage of Meckel becomes resorbed in perinatal ontogenetic stages. Posteriorly, the prearticular fuses with the cartilaginous caput of the malleus; rostrally, the prearticular (= processus gracilis) is always fixed to the anterior crus of the ectotympanic by an extremely thin splint (thickness < 50 µm). From the rostral part of the processus gracilis all studied cetartiodactyls develop a processus internus of considerable size. This process was known as 'ossiculum accessorium mallei' in former times, and its homology has been disputed; from our microscopic-anatomical study we can definitely state that it is always a 'processus internus praearticularis'. This process contacts the fascia of the tensor tympani muscle. In non-ruminants, it articulates dorsally with the tegmen tympani and dorsolaterally with the ectotympanic; whereas the processus gracilis becomes more and more slender, the processus internus may grow to considerable size and normally is fused to the adjacent bones already in juveniles. However, in ruminants, the tegmen tympani tends to disappear and the processus internus praearticularis appears as relatively small bony knob at the floor of the medial cranial cavity, and it seems not to be fused to the surrounding bones; in later age stages, it may become secondarily overgrown by the petrosal. This dorsally exposed processus internus praearticularis seems to be a synapomorphy of the Ruminantia. The functional meaning of this internal process of the prearticular, which is also developed to a minor degree in Carnivora, remains unclear at the moment - but we present some speculations about this.

[Ab] Resumo:Knowledge of the vascularization of the malleus may help to better understand some unwanted effects occurred in those surgical techniques using the handle as an attachment site of ossicle-replacement prostheses. Our hypothesis is that vascular damage occurred in the long process of the malleus during tympanic membrane detachment before fastening a malleovestibulopexy (MVP) prosthesis promotes the lysis of this ossicle at the attachment site. To confirm this premise, we carried out an evolutive and descriptive study of ten MVP procedures as well as a morphological analysis of ten cadaveric mallei using both light and scanning electron microscopies. The arterial supply of the manubrium comes from two main sources: vascular branches that reach this ossicle from the site of insertion of the tensor tympani tendon and small perforating branches which penetrate the bone from arteries of the tympanic membrane that, following the periosteum/perichondrium, they arrange parallel to the bone. The detachment of the tympanic membrane to fasten a MVP prosthesis causes a damage in the periosteal/perichondral vascular supply of the handle as well as micro-trauma on it, which can promote bone resorption at the point of anchorage by osteoclast stimulation. Respect periosteal vascularization of the manubrium may be important to prevent damage in this ossicle caused by some middle ear reconstruction prostheses.

[Ab] Resumo:BACKGROUND: In the cholesteatoma surgery ossicles can be replaced to reconstruct middle ear function. It is important that these ossicles are free of squamous epithelium, to prevent residual disease. This study focuses on the histological findings of the malleus and incus harvested during cholesteatoma surgery. MATERIALS AND METHODS: Eighty middle ears ossicles were examined in vivo and histologically to consider the relationship of cholesteatoma to ossicles, grade of bone destruction and invasion of cholesteatoma to deeper layers of bone. RESULTS: Serious ossicular destruction was observed more frequently in incus compared to malleus (p=0.0065). Difference of ossicles destruction between children and adults was not significant (p=0.3032). Deep invasion of cholesteatoma into the vascular spaces or inner core of the bone was not observed. CONCLUSIONS: Autograft ossicles from cholesteatomatous ears should not necessarily be rejected for reconstruction of the ossicular chain. Regarding the histological finding, the authors suggest mechanical cleaning of the ossicle surface to eliminate residual disease.

[Ab] Resumo:OBJECTIVE: To explore the clinical characteristics, diagnosis and surgical management of tympanosclerosis. METHOD: The data of 73 patients who underwent surgery for tympanosclerosis were retrospectively analyzed with respects to the clinical characteristics, diagnosis and management. RESULT: Seventy-three patients with tympanosclerosis (involving 73 ears) , including 17 patients with sclerosis of tympanic membrane (type I), 23 patients with fixed Malleus-incus complex (type II), 8 (type III) with fixed stapes, and 25 (type IV) with extensive typannosclerosis. Sclerosis was seen most frequently in the malleus, incus and attic, followed by the tympanic membrane, incudomalleolar joint and other regions. Audiometry was performed for all the patients 1 weeks before and 1 year( the least) after operation, which were (51.70 ± 14.93)dB HL and (36.24 ± 11.58) dB HL respectively, with success rate 83% (61/73). CONCLUSION: Most of the patients suffer from conductive hearing loss. Teatment of the sclerosis around stapes is a key point. Acording to the sites of lesion and hearing level, hearing structures should be reconstructed by the rules of tympanoplasty and stapes surgery.
