Brief Summary:
The aim of the study is to evaluate adenoidectomy with bilateral partial tonsillectomy compared with adenoidectomy with classical unilateral complete tonsillectomy for management of pediatric Obstructive Sleep-Disordered Breathing (OSDB) in terms of efficacy of the technique and reducing postoperative complications.

Condition or disease Intervention/treatment
Obstructive Sleep Disordered Breathing Other: adenotonsillectomy

Detailed Description:

Tonsillectomy is one of commonly performed pediatric otorhinolaryngology surgeries.

The two main indications of tonsillectomy in children include recurrent tonsillitis and Obstructive Sleep-Disordered Breathing (OSDB); including obstructive sleep apnea and upper airway resistance syndrome.

Total tonsillectomy means total removal of the tonsillar tissue with the tonsillar capsule. The main drawbacks of tonsillectomy are the potential for serious postoperative bleeding, postoperative pain, eating and drinking difficulties, and reduced immune function in the early stages after the operation. Partial tonsillectomy (intracapsular tonsillectomy, subtotal tonsillectomy) means subtotal removal of tonsillar tissue, leaving a margin of tissue on the tonsillar capsule . In contrast to complete tonsil removal, Partial tonsillectomy does not violate the capsule, and leaves lymphoid tissue as a protective tissue on the pharyngeal muscle layer thus preserving of the connective tissue capsule and pharyngeal muscles. This diminishes the direct and indirect trauma during an intraoperative procedure and the inflammation due to secondary infection during the postoperative period. Recently, children with OSDB have benefited from the less invasive partial tonsillectomy with less pain, equivalent or easier recovery, better food intake, and maintain the immunological function of the tonsils, while being as effective as tonsillectomy for resolving upper-airway obstructive symptoms.

Many studies have evaluated the outcomes of the two techniques, but uncertainty remains with regard to the efficacy, complications and long term outcomes. Some studies have reported the recurrence of obstructive symptoms due to regrowth of the remaining tonsillar tissue. Thus, it is important to evaluate Partial tonsillectomy comprehensively, especially paying attention to short-term and long-term results.

Over the last years, unilateral complete tonsillectomy (usually combined with adenoidectomy) was the most commonly utilized procedure for treatment of pediatric obstructive sleep-disordered breathing below the age of four years old in Otorhinolaryngology Department, Assiut University

Primary Outcome Measures :
  1. postoperative pain assessed by cries scale [ Time Frame: two weeks ]
    The CRIES scale is used for infants > than or = 38 weeks of gestation. Characteristics of crying, oxygen requirement, changes in vital signs, facial expression, and sleep state are scored. A maximal score of 10 is possible. If the CRIES score is > 4, further pain assessment should be undertaken, and analgesic administration is indicated for a score of 6 or higher.
