1) Introduction: Ventilation disorders of the middle ear play a major role in everyday clinical ENT-practice and sometimes represent a major therapeutic challenge. In addition to the conventional therapy of tympanostomy tube insertion, tuboplasty (TP) offers a less invasive option for treating this problem. The study should examine whether TP can be performed in a rural setting. 2) Material and methods: This is a prospective, monocentric study of patients scheduled for TP because of tubal ventilation disorder (TVD) in a rural region of Germany. The diagnosis was established after a thorough clinical examination and by assessing the possibility of performing the Valsalva maneuver, the tympanogram type, recording the middle ear pressure and air-bone gap. The subjective impairment caused by the TVD was evaluated using the EDTQ-7 questionnaire pre- and approximately 3 months postoperatively. 3) Results: Sixty-two patients with 92 TP were included with a mean age of 44.1 years. The EDTQ-7 score decreased highly significantly from 3.6 to 1.7 (p king. Middle ear pressure fell in average by −87 daPa, resulting in an improvement of the tympanogram type. The preoperative air-bone gap of 10.2 dB also was reduced significantly in most patients to 8.0 dB after the procedure. No notable complications occurred beside a sore throat due to the use of a laryngeal mask for ventilation during anesthesia in two cases. 4) Conclusion: In our experience, TP represents a less invasive and, in many cases, successful alternative to the established tympanostomy tube insertion with the advantage of an intact eardrum. It can also be offered and successfully performed in a rural setting.
