**Core Concept**
Vocal nodules are benign lesions that develop on the vocal cords due to vocal abuse or misuse, leading to voice strain and hoarseness. The treatment of early cases aims to prevent further damage and promote healing.

**Why the Correct Answer is Right**
The correct treatment for early cases of vocal nodules involves voice therapy, which is a non-invasive approach that focuses on modifying vocal technique and reducing voice strain. Voice therapy can help to break the cycle of vocal abuse and promote vocal cord healing. This approach is often recommended as a first-line treatment for early cases of vocal nodules, as it is less invasive and has fewer risks compared to surgical options.

**Why Each Wrong Option is Incorrect**
**Option A:** Surgical removal of vocal nodules is generally reserved for cases where voice therapy has failed or is not feasible. It is not the recommended initial treatment for early cases of vocal nodules.
**Option B:** Steroid injections into the vocal cord can be used to reduce inflammation and swelling, but they are not a primary treatment for vocal nodules and may not address the underlying cause of vocal strain.
**Option C:** Resting the voice is an important aspect of vocal care, but it is not a specific treatment for vocal nodules and may not be sufficient to promote healing in early cases.

**Clinical Pearl / High-Yield Fact**
Voice therapy should be initiated promptly in early cases of vocal nodules to prevent further damage and promote vocal cord healing. A multidisciplinary approach involving an otolaryngologist, speech-language pathologist, and vocal coach may be necessary to optimize treatment outcomes.

**Correct Answer:** A. Voice therapy.
