Brief Summary

Background: To compare the efficacy of tonsillectomy and expansion sphincter pharyngoplasty (ESP) in the surgical treatment of obstructive sleep apnea (OSA). Methods: Patients with Friedman grade III-IV tonsil hypertrophy and OSA diagnosed with polysomnography were separated into two groups according to the surgery performed, as the classic tonsillectomy group (Group 1) and the ESP group (Group 2). The primary endpoint of the study was to determine the Apnea-Hypopnea Index (AHI) value. The preoperative and postoperative AHI scores and the decreases in these scores were noted. The change in AHI was calculated as a percentage (preoperative AHI - postoperative AHI/ preoperative AHI x 100) and the two groups were compared. An AHI value of \<10 events/hour was accepted as cure.

Outcome Measures

Primary Outcomes (1)

  • Apnea-Hypopnea Index (AHI)

    The patients were separated into 3 subgroups according to the severity of OSA determined in the PSG recording: mild (AHI ≥ 10 and \<15 events/hr), moderate (AHI ≥15 and \<30 events/hr), and severe (AHI ≥ 30 events/hr). The preoperative and postoperative AHI scores and the decreases in these scores were noted. The change in AHI was calculated as a percentage (preoperative AHI - postoperative AHI/ preoperative AHI x 100) and the two groups were compared. An AHI value of \<10 events/hr was accepted as cure. Success was considered as postoperative AHI \<20 events/hr or a 50% reduction in the preoperative AHI.

Study Arms (2)

Tonsillectomy

EXPERIMENTAL

Tonsillectomy was performed with cold dissection including the whole tonsil and capsule, and bleeding was controlled with bipolar cauterisation.

Procedure: Tonsillectomy

Expansion sphincter pharyngoplasty

EXPERIMENTAL

In the ESP technique, following bilateral tonsillectomy with cold dissection and bleeding control with bipolar cauterisation, the palatopharyngeus muscle was identified and a superior-based muscle flap was formed by cutting the upper two-thirds of the muscle on both sides from the lower third attachment site. By opening tunnels to the anterior plica mucosa, the dissected palatopharyngeus muscle was placed in these tunnels, and was sutured to the pterygomandibular raphe with vicryl 2-0 sutures. The mucosal cuts were closed with vicryl 3-0 sutures
