AHI Scoring and OSA Severity
The Apnoea-Hypopnoea Index (AHI) defines the number of apnoeas and hypopnoeas per hour of sleep and is graded as mild (5–14.9), moderate (15–29.9) and severe (≥30) per the AASM/AAO-HNS classification.
AHI Scoring and OSA Severity is a concept in general ENT whose meaning becomes clear only when it is linked to examination findings. The Apnoea-Hypopnoea Index (AHI) defines the number of apnoeas and hypopnoeas per hour of sleep and is graded as mild (5–14.9), moderate (15–29.9) and severe (≥30) per the AASM/AAO-HNS classification. Age, symptom duration, comorbidities, earlier treatment and daily limitation can all change the interpretation. the clinical point assessment brings nasal-sinus symptoms, the dictionary entry throat-tonsil context, this topic upper-airway impact and this term sleep links into one ENT frame. In this the finding practice approach, the term explains which finding is being assessed and why it matters. The first clinical frame for this entry is to separate functional impact from safety concerns: Apnoea: ≥90% airflow cessation, ≥10 s. This distinction prevents rushed treatment decisions.
In the first visit for the clinical point, the patient's goal and safety boundary are clarified. Duration, side, daily impact, response to medication or surgery and current reports are read together. the dictionary entry review may combine ENT examination, this entry endoscopic assessment, the clinical point oral cavity-oropharynx inspection and the dictionary entry audiological testing when useful. this topic decisions record fever, this term pain-bleeding pattern, the finding hearing or nasal blockage, this entry sleep impact and the clinical point infection recurrence separately. Assessment of the dictionary entry looks for consistency between history and examination: Untreated severe OSA carries 3× cardiovascular mortality and 2× motor vehicle accident risk. If findings do not match, staged reassessment or a second opinion may be clearer than moving directly to a procedure. Laboratory work, audiology, endoscopy, ultrasound, CT, MRI or biopsy is requested only when it improves decision quality.
A this topic plan aims to reduce symptoms without adding unnecessary procedural burden. Mild stable findings are discussed as lower-urgency observation points, while progressive or structural changes are handled with more caution. the clinical point planning discusses medical treatment, the dictionary entry allergy control, this topic endoscopic procedures, this term adenoid-tonsil strategy or the finding airway surgery by indication. The goal in this entry is not to choose the most aggressive option, but to find the right step between safe observation and effective intervention. Options are ordered by comparing short-term relief with preservation of long-term function.
Monitoring for the clinical point compares previous examination, imaging, tests or operation notes with the current picture. the dictionary entry follow-up compares pain, this topic nasal openness, this term sleep quality, the dictionary entry hearing impact and this topic infection recurrence over time. When this term is explained, patient goals, medical necessity and realistic expectations meet on the same ground. Follow-up advice separates warning signs without creating panic; the finding assessment with respiratory difficulty, one-sided worsening, bleeding or child growth impact deserves reassessment.
This this entry entry prepares patients and relatives but does not diagnose. Safer conclusions come from combining the complaint with examination findings, test results when needed, risk profile and a review plan.
Before the visit patient expectations shortens the patient story; For terminology clarity, scoring history, severity assessment, scoring review, severity report language, scoring definition, severity history clarify the patient question.

Diagnosis
Polysomnography (PSG) is the gold standard: simultaneously records AHI, oxygen saturation curve, EEG sleep stages, and respiratory effort. Home sleep apnoea testing (HSAT/type 3) provides ambulatory AHI but lacks EEG, so it is not preferred for mild-moderate cases. The Epworth Sleepiness Scale (≥10 pathological) and STOP-BANG questionnaire (≥3 high risk) are screening tools.
Treatment
CPAP is first-line therapy for moderate-severe OSA. Mandibular advancement devices (MAD) are used for mild-moderate cases and CPAP-intolerant patients. Upper airway surgery (UPPP, tonsillectomy, septoplasty, genioglossus advancement) corrects anatomy but is not curative as monotherapy. Hypopharyngeal surgical options (TORS tongue base reduction, epiglottopexy) are applicable in selected cases.
When to Seek Care
Any patient with witnessed apnoeas, nocturnal choking awakenings, morning headache, or excessive daytime sleepiness (ESS ≥10) should be referred for polysomnography. If AHI >10 or symptoms persist despite CPAP, ENT assessment for positional OSA, mouth opening, and craniofacial anomalies is recommended.
