The original method for bypass surgery of the tympanic cavity to treat chronic dysfunction of the Eustachian tube

✓Spontaneous tension pneumocephalus (TPC) related to shunt surgery has sometimes been reported with reference to the Valsalva maneuver and osseous defects of the tegmen tympani. Here, the authors report on a case of TPC complicated by eustachian tube (ET) insufflation and a ventriculoperitoneal (VP) shunt. This 78-year-old man had undergone VP shunt insertion 3 weeks before readmission to the hospital with a diagnosis of TPC, a left temporal porencephalic cyst, and air accumulation and late leakage of cerebrospinal fluid (CSF) into the left tympanic cavity. The TPC was controlled successfully by ligation of the shunt tube. The authors discuss the pathophysiology of this complicated TPC case, which illustrates the risk of ET insufflation in patients undergoing CSF shunt surgery.

The objective of the current study was to determine the anatomical features of the tympanic cavity in cattle and buffalo and to be recognize all parts of the tympanic cavity for its clinical purposes. There are general anatomical explanation about the middle ear in anatomy text book, however there are no studies in the literature on the morphology of the tympanic cavity in the buffalo, the region is important clinically as a frequent point of attachment for prostheses. As a recent studies have focused on the reconstruction of defects occurring in these tympanic cavity to aid in the development of new surgical technique. Twelve temporal bones from six heads of adult cattle and buffalo were used, the cavity had been investigated on both sides after dissection them, the features of the cavity were assessed with a measurement done by using digital veirenear calipers and measurement tap and photograph by a stereomicroscope. The result show that the tympanic cavity can be divided into three parts, dorsal (epitympanic recess) middle (proper tympanic cavity) and ventral (tympanic bulla), size communicating freely with each other. Epitympanic recess has handle the head of the malleus ,which embedded in the medial surface of tympanic membrane , the proper tympanic cavity has three ossicles are connected to each other , in buffalo being the most developed and the ossicles of the cattle are relatively small , but the incus is more pronounced. Malleus is intimately fused with the incus, it was therefore not possible to separate the malleus and incus. The proper tympanic cavity has tympanic membrane the membrane can be divided into pars flaccids and pars tensa, in buffalo was more development, large in size and oval in shape, with a darker color and thick, but in cattle was rectangle in shape, with a lighter color and thin comparative with buffalo. The tympanic cavity has two skeletal muscles (stapedius and tensor tympanic muscles), the stapedius muscle is ill developed and the greater part of the tensor tympanic muscle was tendinous in buffalo. The proper tympanic cavity has four opening, the external acoustic meatus, the fenestra ovals, the fenestra rotundum and the Eustachian tube. The first three opening are closed by membrane partitions, the Eustachian tube or the auditory tube is short, and (4-5) cm in length and this can clearly why the tympanic cavity of the animal is easily susptable for infections. The ventral of the tympanic cavity was sieve - like present large number of formation which continues with the air cell of the tympanic bulla, the cell which lie directly ventral to the proper tympanic cavity was communicate with those around the external acoustic meatus and facial canal .

Mean Time

Eustachian tube dysfunction is one of the well-known factors leading to development of chronic suppurative otitis media. Tube mucociliary transport is important for elimination of the inflammation products from the middle ear enabling recovery of the affected mucosa of the middle ear, local circulation and restoration of normal air pressure in the middle ear. The study was aimed at determining: 1. whether perforation site on the tympanic membrane influences tube mucociliary transport time in individuals with traumatic rupture of the eardrum; 2. possible time difference of tube mucociliary transport between group of patients with chronic suppurative otitis media and group of patients with traumatic rupture of the tympanic membrane; 3. possible time difference of tube mucociliary transport between chronic tubotympanic type of suppurative otitis media, so called tubotympanic otitis media and atticoantral type of chronic suppurative otitis media, the so called atticoantral otitis; 4. the association between the degree of defect of the tympanic membrane mucosa and time of tube mucociliary transport in each individual type of chronic suppurative inflammation of the middle ear. Eustachian tube mucociliary transport was studied in 16 patients with tubotympanic otitis, in 13 patients with atticoantral otitis and in 9 patients with traumatic rupture of the eardrum (control group of patients). All patients were treated at the Institute of Otorhinolaryngology and Maxillofacial Surgery, Clinical Centre of Serbia in Belgrade during 2002. Tube mucociliary transport was studied upon instillation of 10 ?l 5% sterile saccharine solution through the existing eardrum perforation in the course of preoperative preparation of the patient for surgical intervention. The time interval from the moment of sterile saccharine solution application till perception of the sweet taste in the mouth and pharynx was measured in studied patients. The obtained results were analyzed using the methods of descriptive and analytical statistics (t-test for small independent samples). The mean time of tube mucociliary transport in patients with traumatic rupture of the tympanic membrane was 7.6 minutes. The mean time of tube mucociliary transport in tubotympanic otitis with normal mucosa of the tympanic cavity promontorium was 15 minutes, while mean time of tube mucociliary transport in tubotympanic otitis with polypoid changes of the promontory mucosa was 24 minutes (t=5.218; p<0.01). Mean time of tube mucociliary transport in atticoantral otitis with normal promontory mucosa of the tympanic cavity was 35.5 minutes, while mean time of mucociliary tube transport in atticoantral otitis with polypoid changes of promontory mucosa was 48 minutes (t=6.99; p<0.01). In the irreversibly changed tympanic cavity mucosa, tube clearance saccharine test was negative even after one hour. The results of our study indicate the possibility that prolonged mucociliary tube transport has greater influence to development of atticoantral otitis rather than to development of tubotympanic otitis. The association between the degree of mucosal defect and time of mucociliary transport was evidenced in both types of chronic suppurative inflammation of the middle ear.

AbstractObjective:We report the first case in the English literature of a patulous eustachian tube occurring after laparoscopic Roux-en-Y gastric bypass surgery for obesity.Method:Case report of a 44-year-old woman who was referred to our ENT clinic complaining of autophonia and bilateral aural fullness. The patient had noticed these symptoms after she had undergone a laparoscopic Roux-en-Y gastric bypass surgery to aid weight loss.Result:On the basis of the medical history, clinical examination and immittance measurement (revealing a change in acoustic immittance synchronous with normal breathing in the right ear), a diagnosis of patulous eustachian tube was made, more severe in the right ear than the left.Conclusion:We report a case of patulous eustachian tube occurring after laparoscopic gastric bypass surgery for weight loss, which could be considered as one of the possible complications of this surgery. Our patient began to notice the symptoms of patulous eustachian tube after a 20 kg weight loss.

Direct Relation

This study was undertaken to clarify the relation between nasal allergy and otitis media with effusion and to observe histologically the allergic changes in the eustachian tube itself in animals. Allergic changes in the eustachian tube and tympanic cavity were clearly observed histologically when the antigen had been introduced into the tympanic cavity of sensitized guinea pigs. On the other hand, administration of the antigen into the nose produced marked allergic changes in the nose and pharynx but no change in the eustachian tube or tympanic cavity. In view of these findings, it is suggested that allergy of the nose bears little direct relation to that of the middle ear and the eustachian tube.

Serous Otitis Media

Serous otitis media is a serosal inflammation of the mucous membrane of the auditory tube and the tympanic cavity which develops on the background of Eustachian tube dysfunction. It is characterized by the presence of seromucous exudate in the tympanic cavity. The disease occurs more often in children than adults.The objective of the research was to compare the effectiveness of different methods of treating serous otitis media.Materials and methods. The study included 46 patients with serous otitis media at the age of 22-55 years. There were 26 females and 20 males who were treated as inpatients and outpatients in the department of microsurgery of ENT-organs in Ivano-Frankivsk Central City Clinical Hospital during 2012-2016. Disease duration ranged from 10-15 days to 1 month. In all the patients, serous otitis media developed on the background of persistent allergic rhinitis. All the patients underwent comprehensive examination: their complaints as well as anamnestic data were analyzed, ENT examination including the endoscopic examination of the nasal cavity and the nasopharynx, otoscopy, audiometry, impedancemetry and laboratory investigations was performed. All patients were divided into 2 groups: Group I included 21 patients receiving conservative therapy for allergic rhinitis and serous otitis media; Group II comprised 25 patients receiving conservative therapy for allergic rhinitis and treatment of serous otitis media applying myringotomy and bypass surgery of the tympanic cavity.Results. The analysis of the study revealed that in 9 patients of Group I, an improvement in hearing occurred on the third-fourth days after treatment. In 12 patients, treatment was ineffective. 14 patients of Group II who underwent myringotomy with the evacuation of the fluid from the tympanic cavity and subsequent injection of glucocorticoids into the tympanic cavity noted an improvement in hearing immediately after the procedure or the day after. In 11 patients of Group II, a thick mucous exudate was obtained during myringotomy. These patients underwent bypass surgery. The shunt was removed after a thorough cleaning of the tympanic cavity as well as the restoration of the auditory tube function.Conclusions. Myringotomy is more effective and rational method of treating serous otitis media. Myringotomy with subsequent bypass surgery is recommended for patients with a thick mucous exudate in the tympanic cavity in order to prevent chronic adhesive otitis as well as to perform a complete sanation of the tympanic cavity and to restore the auditory tube function.
