Introduction Autologous reshaped Incus and Teflon partial ossicular replacement prosthesis (PORP) are commonly used for ossicular chain reconstruction. The present study attempts to assess the post-operative outcome with these two prostheses. Materials and Methods  A Randomized prospective study was conducted in Tertiary referral care hospital to determine which material, among autologous reshaped Incus and Teflon partial ossicular replacement prosthesis (PORP) gives better postoperative hearing result in Ossiculoplasty. Patients presenting at outpatients’ department with the clinical diagnosis of chronic otitis media with perforation or retraction. The study population consisted of a total of 50 patients. Ossiculoplasty with reshaped Incus or PORP was performed after Canal Wall Up mastoidectomy. Hearing results were measured by Air-Bone gap in PTA after 6 months of surgery. Results  Selecting the criteria <20 dB ABG as success when Stapes superstructure is present, Incus has 64.29% success rate, whereas PORP has 31.81% success. Extrusion rate of different prosthesis shows PORP has 18.18% extrusion whereas autologous Incus has lower (7.14%) extrusion rate. Conclusion  Among these two ossiculoplasty materials, autologous Incus gives better postoperative hearing gain and lower extrusion rate.

AbstractObjectives:After tympanoplasty using a total ossicular replacement prosthesis, many unsatisfactory hearing results are due to dislocation of the prosthesis.Material and methods:We developed a cartilage guide for stabilising the total ossicular replacement prosthesis in the oval window niche. An oval-shaped piece of cartilage measuring 2.5 × 3.5 mm with a central hole was precisely punched out of a thin cartilage plate. The cartilage was placed in the oval niche, and its hole centred the prosthesis on the stapes footplate.Results:Hearing results in 52 patients confirmed acoustically the effectiveness of this method of total ossicular replacement prosthesis stabilisation on the stapes footplate. Subsequent ‘second-look’ surgery revealed stable ingrowth of the cartilage ‘shoe’ into the oval niche.Conclusion:Such a cartilage shoe might address one of the causes of unsatisfactory hearing following ossicular chain reconstruction with a total ossicular replacement prosthesis.

Introduction Ossicular chain reconstruction is the surgical procedure used to correct the hearing problems in patients with chronic otitis media (COM). In this era, where a large variety of innovative artificial prosthetic materials are being used to replace and reconstruct the ossicular chain, autografts still play a significant role. Materials and Methods The present study included 40 patients. Study population was selected based on inclusion and exclusion criteria. The ossicular reconstructive procedure was done under anesthesia and according to the status of the ossicular chain. Temporalis fascia was used to close the perforation. Mainly two procedures were performed: one is intact canal wall and the other is canal wall down.  Results Most of the study population was middle aged and males were more compared to females. Thirty five patients had air bone gap above 30dB. In 38 patients, the incus had undergone necrosis. Most of the patients underwent short columella reconstruction. A closure of air bone gap with in 20 dB was achieved in 72.2% in patients with malleus stapes assembly. In short columella 22.2% of patients had closure of air bone gap within 20 dB. Incus remnant grafts gave better hearing gain. Discussion The published literature on the result of use of sculptured ossicle and cartilage in tympanoplasty have been reviewed Conclusion In the present study, cases with COM showed good hearing results patients implanted with autogenous cartilage and bone.

Background: No studies have investigated the results of ossicular chain reconstruction using mastoid cortical bone ossiculoplasty (MCBO) and titanium total ossicular replacement prosthesis (TiTORP) in Austin-Kartush Group D cholesteatoma patients with severe middle ear risk index (MERI). Objectives: The present study aimed to compare the hearing results of MCBO and TiTORP in Austin-Kartush Group D cholesteatoma patients with severe MERI who underwent ossicular chain reconstruction during primary surgery. Methods: The hearing results of 28 adult cholesteatoma patients who underwent tympanomastoidectomy and ossicular chain reconstruction with MCBO (n=15) or TiTORP (n=13) were analyzed in the current study. The postoperative hearing was tested 12 months after the surgery. The hearing-related functional success rate was determined in accordance with the American Academy of Otolaryngology-Head and Neck Surgery Foundation criteria. Results: When all patients were taken into account, the mean preoperative and postoperative air-bone gaps (ABG) were reported as 32.2 decibel (dB) and 17.6 dB, respectively, (P<0.001). In 57.1% of the patients, the mean postoperative ABG was ≤ 20 dB. The mean preoperative and postoperative ABGs of the MCBO group were obtained at 29.9 and 16.2 dB, while these values were reported as 35.0 and 19.3 dB in the TiTORP group (P=0.001 and P<0.001, respectively). Hearing-related functional success rates were calculated at 60.0% and 53.8% in MCBO and TiTORP groups, respectively, without any significant difference between the groups (P= 0.743). Conclusion: As evidenced by the obtained results, MCBO and TiTORP can provide similar and successful hearing results in Austin-Kartush Group D patients with cholesteatoma; nonetheless, MCBO is a more cost-effective option in this regard.

Abstract Objective To compare the results of endoscopic and microscopic ossicular chain reconstruction surgery. Methods Patients undergoing ossicular chain reconstruction surgery via an endoscopic (n = 31) or microscopic (n = 34) technique were analysed for age, gender, Middle Ear Risk Index, ossicular chain defect, incision type, ossicular chain reconstruction surgery material, mean air conduction threshold, air–bone gap, air–bone gap gain, word recognition score, mean operation duration and mean post-operative follow up. Results Post-operative air conduction, air–bone gap and word recognition score improved significantly in both groups (within-subject p < 0.001 for air conduction and air–bone gap, and 0.026 for word recognition score); differences between groups were not significant (between-subject p = 0.192 for air conduction, 0.102 for air–bone gap, and 0.709 for word recognition score). Other parameters were similar between groups, except for incision type. However, endoscopic ossicular chain reconstruction surgery was associated with a significantly shorter operation duration (p < 0.001). Conclusion Endoscopic ossicular chain reconstruction surgery can achieve comparable surgical and audiological outcomes to those of microscopic ossicular chain reconstruction surgery in a shorter time.

Conductive Hearing

Proteus syndrome (PS) is a rare hamartomatous disorder characterized by mosaic overgrowth of multiple tissues that manifests early in life and is progressive. The presence of unilateral external auditory canal exostoses in a patient who is not a swimmer or surfer is suggestive of PS. However, hearing loss is not a typical feature. Here, we describe exostoses and ossicular discontinuity with conductive hearing loss in a patient with PS. The treatment consisted of canalplasty and ossicular chain reconstruction. A postoperative reduction was demonstrated in the patient's air-bone gap, from 21 dB to 13 dB for the pure tone average (four frequencies) and from 41 dB to 15 dB in the high-frequency range (6,000 to 8,000 Hz). Causes of ossicular discontinuity are discussed. Routine annual audiometric and otolaryngological evaluation should be considered in all patients with temporal bone inyolvement of PS.

Ossicular Chain Reconstruction

Objectives: In Ethiopia, 2-stage operations with middle ear prostheses are economically unfavorable. We hypothesized that single-stage autologous ossiculoplasty results in acceptable tympanic membrane (TM) and hearing improvements in a setting of limited resources. Methods: One hundred eighty-eight patients (197 ears) who underwent 1-stage autologous ossiculoplasty for ossicular dysfunction are presented. All but 14 of these ears also had perforations of the TM. Conditions of the middle ear were granulation tissue, ossicular disruption only, tympanosclerosis, and cholesteatoma. Reconstructions of the ossicular chain were performed with autologous ossicles only. Results: The closure rate of TM perforations was 95%. Preoperative air bone gaps were 27 to 60 dB (mean [SD] = 44 [7] dB); postoperative air bone gaps were 0 to 50 dB (average [SD] = 23 [10] dB), for an average improvement of 21 dB across all reconstruction types ( P < .001). The largest favorable changes in air bone gaps were with incus and malleus columellas from the footplate to the TM (33 and 23 dB, respectively) ( P < .001). No patient had worsening of sensorineural hearing levels or extrusion of the reconstructed ossicles. Conclusion: Autologous ossiculoplasty performed well in this setting. Acceptable TM closure rates and improvement of air bone gaps were seen in 1-stage operations without the use of prostheses.
