A study of 15 patients with 17 tympanic membrane perforations resulting from water sports was carried out. Most small perforations healed spontaneously. Perforations that persisted after 8 weeks were treated surgically, usually with the office paper patch procedure. A frequent history of middle ear problems in these patients suggests that middle ear dysfunction may play a role in the occurrence and delayed healing of traumatic perforations.

Abstract Introduction The effects of tympanic membrane perforations on middle ear sound transmission are not well characterized, largely because ears with perforations typically have additional pathological changes. It has been established that the larger the perforation, the greater is the hearing loss (HL). Aim This study aimed to correlate the location and size of tympanic membrane perforation and middle ear air space volume with the magnitude of HL in patients with tubotympanic or inactive mucosal type of chronic otitis media (COM). Materials and Methods A prospective clinical study of patients with tympanic membrane perforations due to COM and without any other ear disease and who attended the Otolaryngology services at our institute between July 2010 and December 2011 was conducted. A total of 300 ears were evaluated by performing otoendoscopy, followed by photo documentation and audiological investigations (pure-tone audiometry and tympanometry). Tympanic membrane perforations were categorized based on their size and location, and the mean air-bone (AB) gap between the various types of perforations was compared and statistically analyzed with significance level of p < 0.05. Results Out of 300 ears, maximum number of ears (n = 124, 41.3%) had large-sized perforations (> 30 mm2) that had a maximum mean AB gap of 26.43 dB, and minimum number of ears (n = 60, 20%) had small-sized perforations (0–9 mm2) that had minimum mean AB gap of 9.12 dB. The remaining were medium-sized perforations that had mean AB gap of 16.13 dB. Depending on the location, maximum were central perforations (n = 198, 66%) and minimum were anterosuperior (AS) perforations (n = 9, 3%). Based on the middle ear volume on tympanometry, maximum ears were of low-volume group (n = 246, 92%) that had larger mean AB gap of 19.96 dB HL when compared with the high-volume group (n = 24, 8%) with 11.80 dB HL. AB gap was maximum at lower frequencies and decreased with increase in frequencies except at 4,000 Hz, that is, 56.9 dB HL at 250 Hz, 42.6 at 500 Hz, 41.5 at 1,000 Hz, 32.4 at 2,000 Hz, and 49.5 at 4,000 Hz. Conclusion HL increases as the area of tympanic membrane perforation increases. There is an inverse relationship between HL and middle ear air space volume. Comparing the small-sized perforations at different sites with the middle ear volume being low, it was found that posterosuperior (PS) perforations had 4 to 7 dB greater HL than AS and anteroinferior (AI). However, the relationship was statistically insignificant. The phase cancellation effect of round window causing greater HL in posteroinferior (PI) perforations does not exist in small- and medium-sized perforations. HL is greater at lower frequencies and less at higher frequencies.

In order to establish a simple stimulus-response characteristic of Eustachian tube physiology in children, the tubal ventilatory function was studied. The parameters of active and passive opening of the tube were measured for three groups of patients with non-intact tympanic membranes. The group with traumatic perforations of the tympanic membrane without any history of middle ear disease had better active equilibration function than the group with chronic otitis media and perforations of the tympanic membrane and the group with tympanostomy tubes in the tympanic membrane. Quantitatively, this could be expressed in terms of residual positive pressures. In the study of repeated inflation of the middle ear, all groups had lower second opening pressures which are attributed to the effect of surface forces.

Cholesteatoma in children may be a sequel to chronic exudative otitis media with tympanic membrane retraction but he the role of grommets in the possible facilitation of squamous epithelial invasion into the middle ear is not yet clear. A retrospective study was made of the history and prior treatment in 25 children who underwent mastoidectomy for cholesteatoma at St. Mary's Hospital between 1975 and 1986. Thirteen patients had undergone previous middle ear aeration procedures which included myringotomy, cortical mastoidectomy and grommets. There was no difference in the site or severity of cholesteatoma in the operated and non-operated cases. Of the seven patients with a history of multiple grommets three had primarily attic, and three had primarily mesotympanic disease. The latter had greater ossicular erosion. One patient with an intact tympanic membrane had grommet insertion subsequently developed a cholesteatoma. While cholesteatoma due directly to the presence of grommets is rare, it appears that children who require multiple grommet insertions constitute a high risk group and should be very closely monitored.

Introduction: Cleft lip and palate is one of the most common congenital anomaly, which contributes to eustachian tube dysfunction leading to impaired middle ear ventilation and middle ear pathology. It has been stated that the timely repair of cleft palate reduces the incidence of otitis media with effusion. Objective: To describe the ear findings in cleft palate patients who have undergone repair of cleft palate. Methodology: A total of 36 (20 male and 16 female) post cleft repair patients underwent Otoscopy and Tympanometry between January to December 2018. Cases with isolated cleft lip, ears with perforation of tympanic membrane and attico-antral disease were excluded. Results: The age range was from 4 years to 24 years, with a mean of 11.34 years. Maximum patients were of the age group of 10- 20 years (18, 50%) followed by that of 5-10 years range (15, 41.66%). Total number of ears examined were 72. Out of a total of 72 ears, 70 (97.2%) had abnormal otoscopic finding with dull tympanic membrane in 37 (51.39%) ears, retracted in 31 (43.05%) and bulging tympanic membrane in 2 (2.78%) cases. Type B curve was the commonest (36, 50%), followed by Type As (24, 33.3%). Type C curve was found in 11(15.3%) ears. Type A curve was found only in one ear. The duration of post-repair of cleft palate ranged from 6 months to up to 16 years with a mean of 8.52; 11 cases(30.56%) had history of repair of cleft palate of more than 10 years duration.16 cases (44.44%) had that of more than 5 years and 9 cases (25%) had less than 5 years history of duration of repair. When correlation was done statistically, the tympanometry findings and duration of repair had a very low correlation (Table 5). The time period of repair had no significant effect on tympanometric ear findings. Conclusion Abnormal otoscopic findings and tympanometric findings were common in post cleft palate repaired patients. The duration of cleft palate repair had low correlation to the tympanometric ear findings.
