In obstructive sleep apnea, lingual tonsillar hypertrophy (LTH) has been suggested as a contributing factor to airway blockage. Objectives: The aim of this work is to demonstrate the polysomnographic indices and their values in OSA patients with LTH before and after the surgical intervention. Materials and Methods: The study was conducted on eighteen patients endoscopically diagnosed as having LTH, with the main complaints being snoring, sleep apnea, and\/or sleep disturbance. Clinical examination, grading of LTH, body mass index (BMI), endoscopic assessment using Muller\u2019s maneuver, and sleep endoscopy were recorded for all patients. The Epworth Sleepiness Scale (ESS) and overnight sleep polysomnography (PSG) were conducted before and after the surgical removal of LTH. All data were submitted for statistical analysis. Results: The mean \u00b1 SD of the AHI decreased from 33.89 \u00b1 26.8 to 20.9 \u00b1 19.14 postoperatively, and this decrease was of insignificant statistical value. The average SpO2 (%) mean \u00b1 SD was 91.14 \u00b1 5.96, while the mean \u00b1 SD of the desaturation index was 34.64 \u00b1 34.2. Following surgery, these indices changed to 96.5 \u00b1 1.47 and 9.36 \u00b1 7.58, respectively. The mean \u00b1 SD of the ESS was changed after the surgery, from 17.27 \u00b1 6.48 to 7.16 \u00b1 3.56. The mean \u00b1 SD of sleep efficacy was 71.2 \u00b1 16.8 and the snoring index mean \u00b1 SD was 277.6 \u00b1 192.37, and both improved postoperatively, to become 88.17 \u00b1 9.1 and 62.167 \u00b1 40.01, respectively. Conclusions: The AHI after lingual tonsillectomy showed no statistically significant change. The changes in the average SpO2 (%), desaturation index, sleep efficiency, snoring index, and Epworth Sleepiness Scale following the surgery were statistically significant.<\/jats:p>","DOI":"10.3390\/medicina58050573","type":"journal-article","created":{"date-parts":[[2022,4,23]],"date-time":"2022-04-23T21:39:45Z","timestamp":1650749985000},"page":"573","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Variations in Polysomnographic Indices of Obstructive Sleep Apnea following Lingual Tonsil Hypertrophy Excision: Is the Difference Significant?"],"prefix":"10.3390","volume":"58","author":[{"given":"Ashraf","family":"Wahba","sequence":"first","affiliation":[{"name":"Department of Otorhinolaryngology, Faculty of Medicine\u2014Damietta, Al-Azhar University, Damietta 34517, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7295-6560","authenticated-orcid":false,"given":"Khaled","family":"Abdelaal","sequence":"additional","affiliation":[{"name":"EPCRS Excellence Center, Plant Pathology and Biotechnology Lab., Faculty of Agriculture, Kafrelsheikh University, Kafrelsheikh 33516, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ayman","family":"Yehia","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Faculty of Medicine, Al-Azhar University, Cairo 11675, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmed","family":"Alsheikh","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Faculty of Medicine, Al-Azhar University, Cairo 11675, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Randa","family":"Abdallah","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Faculty of Medicine-Girls, Al-Azhar University, Cairo 11651, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zakaria","family":"Ahmed","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine, Al-Azhar University, Cairo 11675, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alaa","family":"Elmazny","sequence":"additional","affiliation":[{"name":"Department of Neurology, Faculty of Medicine, Cairo University, Cairo 11956, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1447-8841","authenticated-orcid":false,"given":"Mohamed","family":"Shams Eldin","sequence":"additional","affiliation":[{"name":"Department of Otorhinolaryngology, Faculty of Medicine, Al-Azhar University, Cairo 11675, Egypt"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,4,22]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"391","DOI":"10.1177\/0194599817740333","article-title":"Incidence of lingual tonsil hypertrophy in adults with and without obstructive sleep apnea","volume":"158","author":"Tang","year":"2018","journal-title":"Otolaryngol.
