The skin on the outer part of the EAM contains hair follicles and wax-producing glands. These are absent on the inner part. The ear is a self-cleansing organ. Cotton buds should not be used—all they do is impact wax within the canal....

AbstractThis article investigates an effective method with which to reconstruct the tragus and external auditory meatus for microtia reconstruction. The external ear was reconstructed using a delayed postauricular skin flap in patients with congenital microtia. After the first stage of delaying the postauricular skin flap and the second stage of otoplasty with ear framework fabricated from autogenous rib cartilage draping with the delayed skin flap, the third stage involved tragus and external auditory meatus canaloplasty. After designing the remnant auricle flap, the lower part was trimmed and the tragus was reconstructed. The upper part was trimmed into a thin skin flap, which was rotated and used to cover the hollowed wound posterosuperior to the tragus so as to mimic the external auditory meatus. If remnant wounds were present, skin grafting was conducted. In total, 121 patients with congenital microtia were treated from March 2010 to March 2016. The reconstructed tragus and external auditory meatus were well formed, and all wounds healed well. No severe complications such as flap necrosis occurred. Six months postoperatively, the morphology of the reconstructed tragus and external auditory meatus was good. Overall, the patients and their families were satisfied. The use of remnant auricle to reconstruct the tragus and external auditory meatus is an effective auricular reconstruction technique.

AbstractBackground:Temporomandibular joint fistula into the external auditory canal is a very rare condition. We report a case of spontaneous fistula which presented with repeated episodes of clear fluid otorrhoea and ear infection.Case report:A 53-year-old woman complained of occasional episodes of clear fluid otorrhoea from the right ear followed by infection. Otoscopic examination showed a normal tympanic membrane and normal skin in the external auditory meatus. Otomicroscopy showed a small punctum on the anteroinferior part of the meatus. Computed tomography identified a foramen of Huschke. Surgery revealed a fistula between the meatus and the temporomandibular joint, which was successfully resolved.Conclusion:This report presents a rare case of a fistula between the temporomandibular joint and the external auditory meatus, associated with Huschke's foramen. Such a defect can be quite difficult to detect. It should be suspected in cases of chronic otorrhoea when neither middle nor external ear disease is apparent. Surgery is usually successful, and is advised in cases with repeated complications.

AbstractConventional external ear swab cultures were compared with cultures obtained from the middle ear, in 25 cases of tubotympanic type (‘safe’), chronic suppurative otitis media. These cultures were identical in 22 of the 25 cases.Anaerobic organisms were isolated in only one case. Mixed infections of both gram-positive and gramnegative organisms were seen in nine cases (36 per cent).Staphylococcus aureus was the commonest single agent isolated (16 cases). Multidrug resistance was seen in 12 of these isolates.

AbstactThe possibility of a noise-induced hearing loss occurring as a result of a high level of sucker-tip noise in myringtomy for seromucinous otitis media is discussed, A group of twenty-four ears is investigated and the noise levels generated by the suction tube are mearsured at operation by means of a probe microphone lowered into the external auditory meatus The conclusions reached are that, although the sound levels attained are at times quite high, they are not of suffcient amplitude, nor are they present for a suffcient length of time, to produce a sencori-neural hearing loss.

Objective: The aim of this study was to analyze the culture antibiogram results of samples obtained directly from the middle ear and/or mastoid cells in the operating room, and from the external auditory canal in the outpatient. Methods: This study was conducted between 2016-2018 in Microbiology and Otorhinolaryngology Department. Swab cultures were obtained through the external ear canal preoperatively in outpatients. Middle ear swabs and mastoid granulation tissue were collected intraoperatively, respectively. Demographic datas, bacterial identifications and antibiotic susceptibilities were compared in both groups. Results: Two hundred thirty eight patients with chronic otitis media were enrolled in the study. Out of the 238 cases, 86 patients had negative culture results. P. aeruginosa (n=44), Coagulase Negative Staphylococcus (n=33), S. aureus (n=27), Proteus mirabilis (n=16) and E. coli (n=10) were the most common grown bacteria in both groups. Most common identified groups were Gram-positive bacteria (n=92), non-fermenter Gram-negative bacteria (n=55) and Enterobactericeae (n=42). Gram-positive cocci were higher in outpatient group, whereas Enterobactericeae were higher in intraoperative group (p<0.05). Antibiotic susceptibilities of P. aeruginosa and S. aureus were found to be lower especially in the preoperative group (p <0.05). Conclusion: P. aeruginosa was the most common bacteria in both preoperative and intraoperative cultures and high ciprofloxacin resistance of the isolates were remarkable. Although contamination is an issue in samples collected from the external ear canal of outpatients using cotton swabs, similar microorganisms grew in outpatient and intraoperative cultures

Introduction: Bacterial and/ or fungal infection of the middle or external ear can be painful and sometimes the infection can be of mixed nature i.e. caused due to both bacteria and fungi. The combination of antibiotics and antifungals can be used for the treatment of mixed ear infections, along with it, anti-inflammatory agent and anaesthetics can be combined to relieve the discomfort caused by the infection. This study was conducted to test the efficacy and safety for the combination of Neomycin, Beclomethasone, Clotrimazole and Lignocaine for the treatment of middle or external ear infection. Method: Of enrolled 200, 177 patients completed the study. Efficacy was evaluated by symptom score (SS) scale which was an eleven-point scale ranging from 0 to 10 where 0 was no symptom to 10 was the maximum tolerated symptoms. All patients were asked to report SS on SS scale for ear pain, ear discharge and ear itching on day 1, 3 and 5. Safety assessment was made by analysing the adverse events reported by the patient. Results: SS of ear pain was reduced from 6.158 at baseline visit to 3.050 at day 3 to 0.468 at day 5. SS of ear discharge reduced from 6.175 at baseline to 2.768 at day 3 to 0.491 at day 5. SS of ear itching reduced from 4.694 at baseline to 1.604 at day 3 to 0.299 at day 5. Conclusion: The investigational product was found to be efficacious and safe for the treatment of otitis media and externa.
